Critical thinking is just one skill crucial to evidence based practice in healthcare and education, write Jonathan Sharples and colleagues , who see exciting opportunities for cross sector collaboration

Imagine you are a primary care doctor. A patient comes into your office with acute, atypical chest pain. Immediately you consider the patient’s sex and age, and you begin to think about what questions to ask and what diagnoses and diagnostic tests to consider. You will also need to think about what treatments to consider and how to communicate with the patient and potentially with the patient’s family and other healthcare providers. Some of what you do will be done reflexively, with little explicit thought, but caring for most patients also requires you to think critically about what you are going to do.

Critical thinking, the ability to think clearly and rationally about what to do or what to believe, is essential for the practice of medicine. Few doctors are likely to argue with this. Yet, until recently, the UK regulator the General Medical Council and similar bodies in North America did not mention “critical thinking” anywhere in their standards for licensing and accreditation, 1 and critical thinking is not explicitly taught or assessed in most education programmes for health professionals. 2

Moreover, although more than 2800 articles indexed by PubMed have “critical thinking” in the title or abstract, most are about nursing. We argue that it is important for clinicians and patients to learn to think critically and that the teaching and learning of these skills should be considered explicitly. Given the shared interest in critical thinking with broader education, we also highlight why healthcare and education professionals and researchers need to work together to enable people to think critically about the health choices they make throughout life.

Essential skills for doctors and patients

Critical thinking is not a new concept in education: at the beginning of the last century the US educational reformer John Dewey identified the need to help students “to think well.” 3 Critical thinking encompasses a broad set of skills and dispositions, including cognitive skills (such as analysis, inference, and self regulation); approaches to specific questions or problems (orderliness, diligence, and reasonableness); and approaches to life in general (inquisitiveness, concern with being well informed, and open mindedness). 4

An increasing body of evidence highlights that developing critical thinking skills can benefit academic outcomes as well as wider reasoning and problem solving capabilities. 5 For example, the Thinking, Doing, Talking Science programme trains teachers in a repertoire of strategies that encourage pupils to use critical thinking skills in primary school science lessons. An independently conducted randomised trial of this approach found that it had a positive impact on pupils’ science attainment, with signs that it was particularly beneficial for pupils from poorer families. 6

In medicine, increasing attention has been paid to “critical appraisal” in the past 40 years. Critical appraisal is a subset of critical thinking that focuses on how to use research evidence to inform health decisions. 7 8 9 The need for critical appraisal in medicine was recognised at least 75 years ago, 10 and critical appraisal has been recognised for some decades as an essential competency for healthcare professionals. 11 The General Medical Council’s Good Medical Practice guidance includes the need for doctors to be able to “provide effective treatments based on the best available evidence.” 12

If patients and the public are to make well informed health choices, they must also be able to assess the reliability of health claims and information. This is something that most people struggle to do, and it is becoming increasingly important because patients are taking on a bigger role in managing their health and making healthcare decisions, 13 while needing to cope with more and more health information, much of which is not reliable. 14 15 16 17

Teaching critical thinking

Although critical thinking skills are given limited explicit attention in standards for medical education, they are included as a key competency in most frameworks for national curriculums for primary and secondary schools in many countries. 18 Nonetheless, much health and science education, and education generally, still tends towards rote learning rather than the promotion of critical thinking. 19 20 This matters because the ability to think critically is an essential life skill relevant to decision making in many circumstances. The capacity to think critically is, like a lot of learning, developed in school and the home: parental influence creates advantage for pupils who live in homes where they are encouraged to think and talk about what they are doing. This, importantly, goes beyond simply completing tasks to creating deeper understanding of learning processes. As such, the “critical thinking gap” between children from disadvantaged communities and their more advantaged peers requires attention as early as possible.

Although it is possible to teach critical thinking to adults, it is likely to be more productive if the grounds for this have been laid down in an educational environment early in life, starting in primary school. Erroneous beliefs, attitudes, and behaviours developed during childhood may be difficult to change later. 21 22 This also applies to medical education and to health professionals. It becomes increasingly difficult to teach these skills without a foundation to build on and adequate time to learn them.

Strategies for teaching students to think critically have been evaluated in health and medical education; in science, technology, engineering, and maths; and in other subjects. 23 These studies suggest that critical thinking skills can be taught and that in the absence of explicit teaching of critical thinking, important deficiencies emerge in the abilities of students to make sound judgments. In healthcare studies, many medical students score poorly on tests that measure the ability to think critically , and the ability to think critically is correlated with academic success. 24 25

Evaluations of strategies for teaching critical thinking in medicine have focused primarily on critical appraisal skills as part of evidence based healthcare. An overview of systematic reviews of these studies suggests that improving evidence based healthcare competencies is likely to require multifaceted, clinically integrated approaches that include assessment. 26

Cross sector collaboration

Informed Health Choices, an international project aiming to improve decision making, shows the opportunities and benefits of cross sector collaboration between education and health. 27 This project has brought together people working in education and healthcare to develop a curriculum and learning resources for critical thinking about any action that is claimed to improve health. It aims to develop, identify, and promote the use of effective learning resources, beginning at primary school, to help people to make well informed choices as patients and health professionals, and well informed decisions as citizens and policy makers.

The project has drawn on several approaches used in education, including the development of a “spiral curriculum,” measurement tools, and the design of learning resources. A spiral curriculum begins with determining what people should know and be able to do, and outlines where they should begin and how they should progress to reach these goals. The basic ideas are revisited repeatedly, building on them until the student has grasped a deep understanding of the concepts. 28 29 The project has also drawn on educational research and methods to develop reliable and valid tools for measuring the extent to which those goals have been achieved. 30 31 32 The development of learning resources to teach these skills has been informed by educational research, including educational psychology, motivational psychology, and research and methods for developing learning games. 33 34 35 It has also built on the traditions of clinical epidemiology and evidence based medicine to identify the key concepts required to assess health claims. 29

It is difficult to teach critical thinking abstractly, so focusing on health may have advantages beyond the public health benefits of increasing health literacy. 36 Nearly everyone is interested in health, including children, making it easy to engage learners. It is also immediately relevant to students. As reported by one 10 year old in a school that piloted primary school resources, this is about “things we might actually use instead of things we might use when we are all grown up and by then we’ll forget.” Although the current evaluation of the project is focusing on outcomes relating to appraisal of treatment claims, if the intervention shows promise the next step could be to explore how these skills translate to wider educational contexts and outcomes.

Beyond critical thinking

Exciting opportunities for cross sector collaboration are emerging between healthcare and education. Although critical thinking is a useful example of this, other themes cross the education and healthcare domains, including nutrition, exercise, educational neuroscience, learning disabilities and special education needs, and mental health.

In addition to shared topics, several common methodological and conceptual issues also provide opportunities for sharing ideas and innovations and learning from mistakes and successes. For example, the Education Endowment Foundation is the UK government’s What Works Centre for education, aiming to improve evidence based decision making. Discussions hosted by the foundation are exploring how methods to develop guidelines in healthcare can be adapted and applied in education and other sectors.

Similarly, the foundation’s universal use of independent evaluation for teaching and learning interventions is an approach that should be explored, adapted, and applied in healthcare. Since the development and evaluation of educational interventions are separated, evaluators have no vested interested in the results of the assessment, all results are published, and bias and spin in how results are analysed and presented are reduced. By contrast, industry sponsorship of drug and device studies consistently produces results that favour the manufacturer. 37

Another example of joint working between educators and health is the Best Evidence Medical Education Collaboration, an international collaboration focused on improving education of health professionals. 38 And in the UK, the Centre for Evidence Based Medicine coordinates Evidence in School Teaching (Einstein), a project that supports introducing evidence based medicine as part of wider science activities in schools. 39 It aims to engage students, teachers, and the public in evidence based medicine and develop critical thinking to assess health claims and make better choices.

Collaboration has also been important in the development of the Critical Thinking and Appraisal Resource Library (CARL), 40 a set of resources designed to help people understand fair comparisons of treatments. An important aim of CARL is to promote evaluation of these critical thinking resources and interventions, some of which are currently under way at the Education Endowment Foundation. On 22 May 2017, the foundation is also cohosting an event with the Royal College of Paediatrics and Child Health that will focus on their shared interest in critical thinking and appraisal skills.

Education and healthcare have overlapping interests. Doctors, teachers, researchers, patients, learners, and the public can all benefit from working together to help people to think critically about the choices they make. Events such as the global evidence summit in September 2017 ( https://globalevidencesummit.org ) can help bring people together and build on current international experience.

The Value of Critical Thinking in Nursing

• How Nurses Use Critical Thinking
• How to Improve Critical Thinking
• Common Mistakes

Some experts describe a person’s ability to question belief systems, test previously held assumptions, and recognize ambiguity as evidence of critical thinking. Others identify specific skills that demonstrate critical thinking, such as the ability to identify problems and biases, infer and draw conclusions, and determine the relevance of information to a situation.

Nicholas McGowan, BSN, RN, CCRN, has been a critical care nurse for 10 years in neurological trauma nursing and cardiovascular and surgical intensive care. He defines critical thinking as “necessary for problem-solving and decision-making by healthcare providers. It is a process where people use a logical process to gather information and take purposeful action based on their evaluation.”

“This cognitive process is vital for excellent patient outcomes because it requires that nurses make clinical decisions utilizing a variety of different lenses, such as fairness, ethics, and evidence-based practice,” he says.

How Do Nurses Use Critical Thinking?

Successful nurses think beyond their assigned tasks to deliver excellent care for their patients. For example, a nurse might be tasked with changing a wound dressing, delivering medications, and monitoring vital signs during a shift. However, it requires critical thinking skills to understand how a difference in the wound may affect blood pressure and temperature and when those changes may require immediate medical intervention.

Nurses care for many patients during their shifts. Strong critical thinking skills are crucial when juggling various tasks so patient safety and care are not compromised.

Jenna Liphart Rhoads, Ph.D., RN, is a nurse educator with a clinical background in surgical-trauma adult critical care, where critical thinking and action were essential to the safety of her patients. She talks about examples of critical thinking in a healthcare environment, saying:

“Nurses must also critically think to determine which patient to see first, which medications to pass first, and the order in which to organize their day caring for patients. Patient conditions and environments are continually in flux, therefore nurses must constantly be evaluating and re-evaluating information they gather (assess) to keep their patients safe.”

The COVID-19 pandemic created hospital care situations where critical thinking was essential. It was expected of the nurses on the general floor and in intensive care units. Crystal Slaughter is an advanced practice nurse in the intensive care unit (ICU) and a nurse educator. She observed critical thinking throughout the pandemic as she watched intensive care nurses test the boundaries of previously held beliefs and master providing excellent care while preserving resources.

“Nurses are at the patient’s bedside and are often the first ones to detect issues. Then, the nurse needs to gather the appropriate subjective and objective data from the patient in order to frame a concise problem statement or question for the physician or advanced practice provider,” she explains.

Top 5 Ways Nurses Can Improve Critical Thinking Skills

We asked our experts for the top five strategies nurses can use to purposefully improve their critical thinking skills.

Case-Based Approach

Slaughter is a fan of the case-based approach to learning critical thinking skills.

In much the same way a detective would approach a mystery, she mentors her students to ask questions about the situation that help determine the information they have and the information they need. “What is going on? What information am I missing? Can I get that information? What does that information mean for the patient? How quickly do I need to act?”

Consider forming a group and working with a mentor who can guide you through case studies. This provides you with a learner-centered environment in which you can analyze data to reach conclusions and develop communication, analytical, and collaborative skills with your colleagues.

Practice Self-Reflection

Rhoads is an advocate for self-reflection. “Nurses should reflect upon what went well or did not go well in their workday and identify areas of improvement or situations in which they should have reached out for help.” Self-reflection is a form of personal analysis to observe and evaluate situations and how you responded.

This gives you the opportunity to discover mistakes you may have made and to establish new behavior patterns that may help you make better decisions. You likely already do this. For example, after a disagreement or contentious meeting, you may go over the conversation in your head and think about ways you could have responded.

It’s important to go through the decisions you made during your day and determine if you should have gotten more information before acting or if you could have asked better questions.

During self-reflection, you may try thinking about the problem in reverse. This may not give you an immediate answer, but can help you see the situation with fresh eyes and a new perspective. How would the outcome of the day be different if you planned the dressing change in reverse with the assumption you would find a wound infection? How does this information change your plan for the next dressing change?

Develop a Questioning Mind

McGowan has learned that “critical thinking is a self-driven process. It isn’t something that can simply be taught. Rather, it is something that you practice and cultivate with experience. To develop critical thinking skills, you have to be curious and inquisitive.”

To gain critical thinking skills, you must undergo a purposeful process of learning strategies and using them consistently so they become a habit. One of those strategies is developing a questioning mind. Meaningful questions lead to useful answers and are at the core of critical thinking .

However, learning to ask insightful questions is a skill you must develop. Faced with staff and nursing shortages , declining patient conditions, and a rising number of tasks to be completed, it may be difficult to do more than finish the task in front of you. Yet, questions drive active learning and train your brain to see the world differently and take nothing for granted.

It is easier to practice questioning in a non-stressful, quiet environment until it becomes a habit. Then, in the moment when your patient’s care depends on your ability to ask the right questions, you can be ready to rise to the occasion.

Practice Self-Awareness in the Moment

Critical thinking in nursing requires self-awareness and being present in the moment. During a hectic shift, it is easy to lose focus as you struggle to finish every task needed for your patients. Passing medication, changing dressings, and hanging intravenous lines all while trying to assess your patient’s mental and emotional status can affect your focus and how you manage stress as a nurse .

Staying present helps you to be proactive in your thinking and anticipate what might happen, such as bringing extra lubricant for a catheterization or extra gloves for a dressing change.

By staying present, you are also better able to practice active listening. This raises your assessment skills and gives you more information as a basis for your interventions and decisions.

Use a Process

As you are developing critical thinking skills, it can be helpful to use a process. For example:

• Ask questions.
• Gather information.
• Implement a strategy.
• Evaluate the results.
• Consider another point of view.

These are the fundamental steps of the nursing process (assess, diagnose, plan, implement, evaluate). The last step will help you overcome one of the common problems of critical thinking in nursing — personal bias.

Common Critical Thinking Pitfalls in Nursing

Your brain uses a set of processes to make inferences about what’s happening around you. In some cases, your unreliable biases can lead you down the wrong path. McGowan places personal biases at the top of his list of common pitfalls to critical thinking in nursing.

“We all form biases based on our own experiences. However, nurses have to learn to separate their own biases from each patient encounter to avoid making false assumptions that may interfere with their care,” he says. Successful critical thinkers accept they have personal biases and learn to look out for them. Awareness of your biases is the first step to understanding if your personal bias is contributing to the wrong decision.

New nurses may be overwhelmed by the transition from academics to clinical practice, leading to a task-oriented mindset and a common new nurse mistake ; this conflicts with critical thinking skills.

“Consider a patient whose blood pressure is low but who also needs to take a blood pressure medication at a scheduled time. A task-oriented nurse may provide the medication without regard for the patient’s blood pressure because medication administration is a task that must be completed,” Slaughter says. “A nurse employing critical thinking skills would address the low blood pressure, review the patient’s blood pressure history and trends, and potentially call the physician to discuss whether medication should be withheld.”

Fear and pride may also stand in the way of developing critical thinking skills. Your belief system and worldview provide comfort and guidance, but this can impede your judgment when you are faced with an individual whose belief system or cultural practices are not the same as yours. Fear or pride may prevent you from pursuing a line of questioning that would benefit the patient. Nurses with strong critical thinking skills exhibit:

• Learn from their mistakes and the mistakes of other nurses
• Look forward to integrating changes that improve patient care
• Treat each patient interaction as a part of a whole
• Evaluate new events based on past knowledge and adjust decision-making as needed
• Solve problems with their colleagues
• Are self-confident
• Acknowledge biases and seek to ensure these do not impact patient care

An Essential Skill for All Nurses

Critical thinking in nursing protects patient health and contributes to professional development and career advancement. Administrative and clinical nursing leaders are required to have strong critical thinking skills to be successful in their positions.

By using the strategies in this guide during your daily life and in your nursing role, you can intentionally improve your critical thinking abilities and be rewarded with better patient outcomes and potential career advancement.

Frequently Asked Questions About Critical Thinking in Nursing

How are critical thinking skills utilized in nursing practice.

Nursing practice utilizes critical thinking skills to provide the best care for patients. Often, the patient’s cause of pain or health issue is not immediately clear. Nursing professionals need to use their knowledge to determine what might be causing distress, collect vital information, and make quick decisions on how best to handle the situation.

How does nursing school develop critical thinking skills?

Nursing school gives students the knowledge professional nurses use to make important healthcare decisions for their patients. Students learn about diseases, anatomy, and physiology, and how to improve the patient’s overall well-being. Learners also participate in supervised clinical experiences, where they practice using their critical thinking skills to make decisions in professional settings.

Do only nurse managers use critical thinking?

Nurse managers certainly use critical thinking skills in their daily duties. But when working in a health setting, anyone giving care to patients uses their critical thinking skills. Everyone — including licensed practical nurses, registered nurses, and advanced nurse practitioners —needs to flex their critical thinking skills to make potentially life-saving decisions.

Cultivating Critical Thinking in Healthcare

Published: 06 January 2019

Critical thinking skills have been linked to improved patient outcomes, better quality patient care and improved safety outcomes in healthcare (Jacob et al. 2017).

Given this, it's necessary for educators in healthcare to stimulate and lead further dialogue about how these skills are taught , assessed and integrated into the design and development of staff and nurse education and training programs (Papp et al. 2014).

So, what exactly is critical thinking and how can healthcare educators cultivate it amongst their staff?

What is Critical Thinking?

In general terms, ‘ critical thinking ’ is often used, and perhaps confused, with problem-solving and clinical decision-making skills .

In practice, however, problem-solving tends to focus on the identification and resolution of a problem, whilst critical thinking goes beyond this to incorporate asking skilled questions and critiquing solutions .

Several formal definitions of critical thinking can be found in literature, but in the view of Kahlke and Eva (2018), most of these definitions have limitations. That said, Papp et al. (2014) offer a useful starting point, suggesting that critical thinking is:

‘The ability to apply higher order cognitive skills and the disposition to be deliberate about thinking that leads to action that is logical and appropriate.’

The Foundation for Critical Thinking (2017) expands on this and suggests that:

‘Critical thinking is that mode of thinking, about any subject, content, or problem, in which the thinker improves the quality of his or her thinking by skillfully analysing, assessing, and reconstructing it.’

They go on to suggest that critical thinking is:

• Self-directed
• Self-disciplined
• Self-monitored
• Self-corrective.

Key Qualities and Characteristics of a Critical Thinker

Given that critical thinking is a process that encompasses conceptualisation , application , analysis , synthesis , evaluation and reflection , what qualities should be expected from a critical thinker?

In answering this question, Fortepiani (2018) suggests that critical thinkers should be able to:

• Formulate clear and precise questions
• Gather, assess and interpret relevant information
• Reach relevant well-reasoned conclusions and solutions
• Think open-mindedly, recognising their own assumptions
• Communicate effectively with others on solutions to complex problems.

All of these qualities are important, however, good communication skills are generally considered to be the bedrock of critical thinking. Why? Because they help to create a dialogue that invites questions, reflections and an open-minded approach, as well as generating a positive learning environment needed to support all forms of communication.

Lippincott Solutions (2018) outlines a broad spectrum of characteristics attributed to strong critical thinkers. They include:

• Inquisitiveness with regard to a wide range of issues
• A concern to become and remain well-informed
• Alertness to opportunities to use critical thinking
• Self-confidence in one’s own abilities to reason
• Open mindedness regarding divergent world views
• Flexibility in considering alternatives and opinions
• Understanding the opinions of other people
• Fair-mindedness in appraising reasoning
• Honesty in facing one’s own biases, prejudices, stereotypes or egocentric tendencies
• A willingness to reconsider and revise views where honest reflection suggests that change is warranted.

Papp et al. (2014) also helpfully suggest that the following five milestones can be used as a guide to help develop competency in critical thinking:

Stage 1: Unreflective Thinker

At this stage, the unreflective thinker can’t examine their own actions and cognitive processes and is unaware of different approaches to thinking.

Stage 2: Beginning Critical Thinker

Here, the learner begins to think critically and starts to recognise cognitive differences in other people. However, external motivation  is needed to sustain reflection on the learners’ own thought processes.

Stage 3: Practicing Critical Thinker

By now, the learner is familiar with their own thinking processes and makes a conscious effort to practice critical thinking.

Stage 4: Advanced Critical Thinker

As an advanced critical thinker, the learner is able to identify different cognitive processes and consciously uses critical thinking skills.

Stage 5: Accomplished Critical Thinker

At this stage, the skilled critical thinker can take charge of their thinking and habitually monitors, revises and rethinks approaches for continual improvement of their cognitive strategies.

Facilitating Critical Thinking in Healthcare

A common challenge for many educators and facilitators in healthcare is encouraging students to move away from passive learning towards active learning situations that require critical thinking skills.

Just as there are similarities among the definitions of critical thinking across subject areas and levels, there are also several generally recognised hallmarks of teaching for critical thinking . These include:

• Promoting interaction among students as they learn
• Asking open ended questions that do not assume one right answer
• Allowing sufficient time to reflect on the questions asked or problems posed
• Teaching for transfer - helping learners to see how a newly acquired skill can apply to other situations and experiences.

(Lippincott Solutions 2018)

Snyder and Snyder (2008) also make the point that it’s helpful for educators and facilitators to be aware of any initial resistance that learners may have and try to guide them through the process. They should aim to create a learning environment where learners can feel comfortable thinking through an answer rather than simply having an answer given to them.

Examples include using peer coaching techniques , mentoring or preceptorship to engage students in active learning and critical thinking skills, or integrating project-based learning activities that require students to apply their knowledge in a realistic healthcare environment.

Carvalhoa et al. (2017) also advocate problem-based learning as a widely used and successful way of stimulating critical thinking skills in the learner. This view is echoed by Tsui-Mei (2015), who notes that critical thinking, systematic analysis and curiosity significantly improve after practice-based learning .

Integrating Critical Thinking Skills Into Curriculum Design

Most educators agree that critical thinking can’t easily be developed if the program curriculum is not designed to support it. This means that a deep understanding of the nature and value of critical thinking skills needs to be present from the outset of the curriculum design process , and not just bolted on as an afterthought.

In the view of Fortepiani (2018), critical thinking skills can be summarised by the statement that 'thinking is driven by questions', which means that teaching materials need to be designed in such a way as to encourage students to expand their learning by asking questions that generate further questions and stimulate the thinking process. Ideal questions are those that:

• Embrace complexity
• Challenge assumptions and points of view
• Question the source of information
• Explore variable interpretations and potential implications of information.

To put it another way, asking questions with limiting, thought-stopping answers inhibits the development of critical thinking. This means that educators must ideally be critical thinkers themselves .

Drawing these threads together, The Foundation for Critical Thinking (2017) offers us a simple reminder that even though it’s human nature to be ‘thinking’ most of the time, most thoughts, if not guided and structured, tend to be biased, distorted, partial, uninformed or even prejudiced.

They also note that the quality of work depends precisely on the quality of the practitioners’ thought processes. Given that practitioners are being asked to meet the challenge of ever more complex care, the importance of cultivating critical thinking skills, alongside advanced problem-solving skills , seems to be taking on new importance.

Background: The epidemiology, clinical course, and outcomes of patients with coronavirus disease 2019 (COVID-19) in the Russian population are unknown. Information on the differences between laboratory-confirmed and clinically diagnosed COVID-19 in real-life settings is lacking.

Methods: We extracted data from the medical records of adult patients who were consecutively admitted for suspected COVID-19 infection in Moscow between 8 April and 28 May 2020.

Results: Of the 4261 patients hospitalized for suspected COVID-19, outcomes were available for 3480 patients (median age, 56 years; interquartile range, 45-66). The most common comorbidities were hypertension, obesity, chronic cardiovascular disease, and diabetes. Half of the patients (n = 1728) had a positive reverse transcriptase-polymerase chain reaction (RT-PCR), while 1748 had a negative RT-PCR but had clinical symptoms and characteristic computed tomography signs suggestive of COVID-19. No significant differences in frequency of symptoms, laboratory test results, and risk factors for in-hospital mortality were found between those exclusively clinically diagnosed or with positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR. In a multivariable logistic regression model the following were associated with in-hospital mortality: older age (per 1-year increase; odds ratio, 1.05; 95% confidence interval, 1.03-1.06), male sex (1.71; 1.24-2.37), chronic kidney disease (2.99; 1.89-4.64), diabetes (2.1; 1.46-2.99), chronic cardiovascular disease (1.78; 1.24-2.57), and dementia (2.73; 1.34-5.47).

Conclusions: Age, male sex, and chronic comorbidities were risk factors for in-hospital mortality. The combination of clinical features was sufficient to diagnose COVID-19 infection, indicating that laboratory testing is not critical in real-life clinical practice.

Keywords: COVID-19; Russia; SARS-CoV-2; cohort; mortality risk factors.

Obtaining and critically appraising evidence is clearly not enough to make better decisions in clinical care. The evidence should be linked to the clinician’s expertise, the patient’s individual circumstances (including values and preferences), and clinical context and settings. We propose critical thinking and decision-making as the tools for making that link.

Critical thinking is also called for in medical research and medical writing, especially where pre-canned methodologies are not enough. It is also involved in our exchanges of ideas at floor rounds, grand rounds and case discussions; our communications with patients and lay stakeholders in health care; and our writing of research papers, grant applications and grant reviews.

Critical thinking is a learned process which benefits from teaching and guided practice like any discipline in health sciences. Training in critical thinking should be a part or a pre-requisite of the medical curriculum.

Sackett et al. originally defined evidence based medicine (EBM) as ‘… the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients’, and its integration with individual clinical expertise [ 1 ].’ In the nearly two decades that have intervened, there has been significant uptake of the idea that clinical care should be based upon sound, systematically researched evidence. There has been less emphasis on how clinical expertise itself might be improved, perhaps because the concept is more amorphous and difficult to define.

Clinical expertise is an amalgam of several things: there must be a solid knowledge base, some considerable clinical experience, and an ability to think, reason, and decide in a competent and well-calibrated fashion. Our focus here is on this last component: the faculties of thinking, reasoning and decision making. Clinicians must be able to integrate the best available critically appraised evidence with insights into their patients, the clinical context, and themselves [ 2 ]. To accomplish this integration, physicians need to develop their critical thinking skills. Yet historically this need has not received explicit attention in medical training. We believe that it should.

As an illustration of the use of critical thinking in clinical care, consider the following clinical scenario from emergency medicine : A 52-year-old male presents to the emergency department of a community centre with a complaint of constipation and is triaged with a low level acuity score to a ‘minors’ area. The department is extremely busy and several hours elapse before he is seen by the emergency physician. His principal complaint is constipation; he hasn’t had a bowel movement for 4 days. His abdomen is soft and non-tender. A large amount of firm stool is evident on rectal examination. He recalls a minor back strain a few days earlier. The physician orders a soapsuds enema and continues seeing other patients. After about 30 minutes he finds the nurse who administered the enema; she reports that it was ineffective. He orders a fleet enema which again proves ineffective. The nurse expresses her opinion that the patient is taking up too much time and suggests he be given an oral laxative and another fleet enema to take home with him. She is clearly unwilling to continue investing her effort in a patient with a trivial complaint. Nevertheless, the physician decides to administer a third enema himself. The third enema is only marginally effective and he then decides to disimpact the patient. The physician notes poor rectal tone and enquires further about the patient’s urination. He says he has been unable to urinate that day. On catheterisation he is found to have 1200cc. Neurological findings are equivocal: reflexes are present in both legs and there is some subjective diminished sensation.

A diagnosis of cauda equina syndrome is made and the emergency physician calls the neurosurgery service at a tertiary care hospital. It is now late in the evening. The neurosurgeon is reluctant to accept the working diagnosis. He suggests that the loss of sphincter tone might be due to the disimpaction, and argues that there was no significant history of back injury or convincing neurological findings. When the ED physician persists, the neurosurgeon suggests transferring the patient to the tertiary hospital ED for further evaluation and asks for a CT investigation of the patient’s lower spine before seeing him. The CT reveals only some minor abnormalities and the patient is kept overnight. An MRI is done in the morning. It shows extensive disc herniation with compression of nerve roots. The patient subsequently undergoes prolonged back surgery.

This case had a good outcome, although things might have been dramatically different. The patient might have suffered permanent neurological injury requiring lifelong catheterisation for urination.

Our scenario illustrates some key points about clinical decision making. At the outset, the patient presents with an apparently benign condition – constipation. The impression of a benign condition is incorporated at triage and results in a low-level acuity score and prolonged wait. The patient’s nurse also incorporates this diagnosis and exerts coercive pressure on the physician to discharge the patient. The neurosurgeon is dismissive of a physician’s assessment in a community centre ED, creating considerable inertia against referral. Thus the ED physician faces a variety of obstacles to ensure optimal patient care. These have little to do with EBM. He must resist and overcome a variety of cognitive, affective and systemic biases, his own as well as others’, and various contextual constraints. He must continue to think critically and persist in a course that has become increasingly challenging.

Our scenario also illustrates some key points about critical thinking. The initial impression of a benign condition of constipation is not the only diagnosis compatible with the patient’s symptoms. A health care professional reaching a preliminary diagnosis must be aware of the danger of fixing prematurely on this diagnosis and ignoring (or failing to look for) subsequent evidence that tells against it, as the nurse in our scenario was inclined to do. Observational and textual studies both indicate that the most common source of errors in reasoning is to close prematurely on a favoured conclusion and then ignore evidence that argues against that conclusion [ 3 ]. It is also important to keep in mind that a patient’s signs or symptoms may have more than one cause. Data that may confirm one of the causes does not necessarily rule out all the others. Attentive listening to the patient and careful looking in the data-gathering stage are essential to good medical practice, as Groopman has recently pointed out [ 4 ]. From a logical point of view, the physician’s diagnostic task is to gather data that will determine which one (or ones) of the possible causes is (or are) responsible for the patient’s problem. This goal will guide the selection of data and of additional tests. ‘Parallel’ or ‘lateral’ thinking [ 5 ] will help with the differential diagnosis.

Critical Thinking

Dewey’s original conceptualization [ 6 ] of what he called “reflective thinking” has spawned in the intervening century a variety of definitions of critical thinking, most notably that of Ennis as “ reasonable reflective thinking that is focused on deciding what to believe or what to do” [ 7 ] . Scriven and Paul have elaborated this definition as “… the intellectually disciplined process of actively and skilfully conceptualizing, applying, synthesizing or evaluating information gathered from, or generated by observation, experience, reflection, reasoning, or communication as a guide to belief or action ” [ 8 ].

The consensus of 48 specialists in critical thinking from the fields of education, philosophy and psychology was that it should be defined as ‘ purposeful self-regulatory judgment which results in interpretation, analysis, evaluation and inference, as well as explanation of the evidential, conceptual, methodological, criteriological, or contextual considerations upon which that judgement is based ’ [ 9 ]. The list of additional definitions remains impressive [ 10 , 11 ].

Even more useful than these definitions are various lists of dispositions and skills characteristic of a “critical thinker” [ 7 , 9 , 12 ]. More useful still are criteria and standards for measuring possession of those skills and dispositions [ 13 ], criteria that have been used to develop standardized tests of critical thinking skills and dispositions [ 14 – 17 ] including some with specific reference to health sciences [ 18 ].

The elements of critical thinking subsume what has variously been described as clinical judgment [ 19 ] , logic of medicine [ 20 , 21 ] , logic in medicine [ 22 ] , philosophy of medicine [ 23 ] , causal inference [ 24 ] , medical decision making [ 25 ], clinical decision making [ 26 ], clinical decision analysis [ 27 ], and clinical reasoning [ 28 ]. An increasing number of monographs on logic and critical thinking in general have appeared [ 29 – 34 ] and their content is being adapted for medicine [ 35 – 37 ].

Everyday medical practice, whether in physicians’ offices or emergency departments or hospital wards, clearly involves “ reasonable reflective thinking that is focused on deciding what to believe (meaning the understanding of the problem) and/or what to do (i.e. deciding what to do to solve the problem)” [ 7 , 38 ]. Table 1 lists specific abilities underlying critical thinking in medical practice.

Specific abilities underlying critical thinking in medical practice.

Critical thinking is also called for in medical research and medical writing. Editors of leading medical journals have called for it. Edward Huth [ 39 , 40 ], former editor of Annals of Internal Medicine, has urged that medical articles reflect better and more organized ways of reasoning. Richard Horton [ 41 , 42 ], former editor of The Lancet , has proposed the use in medical writing of a contemporary approach to argument along the lines used by the philosopher Toulmin [ 40 , 41 ]. Subsequently, two of us have developed this approach in detail for medicine [ 43 , 44 ]. Dickinson [ 45 ] has called for an argumentative approach in medical problem solving and brought it to the attention to the world of medical informatics and beyond.

Dual Process Theory

An important component of critical thinking is being aware of one’s own thinking processes. In recent years, two general modes of thinking have been described under an approach described as dual process theory. The model is universal and has been directly applied to medicine [ 46 – 48 ] and nursing [ 49 ]. One mode is fast, reflexive, autonomous, and generally referred to as intuitive or System 1 thinking. The other is slow, deliberate, rule-based, and referred to as analytical or System 2 thinking. The mechanisms that underlie System 1 thinking are based on associative learning and innate dispositions: the latter are hard-wired, as a result of the evolutionary history of our species, to respond reflexively to certain cues in the environment. We have discrete, functionally-specialized mental programs that were selected when the brain was undergoing significant development especially spanning the last 6 million years of hominid evolution [ 50 ]. Although these programs may have served us well in our ancestral past, they may not be appropriate in some aspects of modern living. Some of this System 1 substrate also underlies various heuristics and biases in our thinking – the tendency to take mental short-cuts, or demonstrate reflexive responses in certain situations, often on the basis of past experience. Not surprisingly, most error occurs in System 1 thinking.

Contemplative , or fully reflective thinking, is System 2 thinking. It suits any practice of medicine or medical research activity where there is time to utilise the best critically appraised evidence in a step-by-step process of reasoning and argument. Contemplative, fully reflective thinking is appropriate, for example, in internal medicine, psychiatry, public health, and other specialties, in etiological research and clinical trials, and in writing up the results of such research [ 35 ].

In contrast, a shortcut or heuristic approach [ 51 ] with somehow truncated thinking is often dictated by the realities of emergency medicine, surgery, obstetrics or any situation where there is incomplete information, bounded rationality, and insufficient time to be fully reflective. The extant findings and the decision maker’s experience are all that is available. The quintessential challenge for well-calibrated decision making is to optimise performance in System 1. Hogarth [ 52 ] sees this challenge as educating our intuitive processes and has delineated a variety of strategies through which this might be accomplished.

No responsible physician would engage in reflective thinking on every occasion when a decision has to be made. Such acute emergencies as sudden complications of labour and delivery, ruptured aneurysms, multiple trauma victims and other immediately life-threatening situations generally leave no time for fully reflective thinking. A shortcut or heuristic approach is required [ 51 ], involving pattern recognition, steepest ascent reasoning, or algorithmic paths [ 21 , 53 ]. There is of course a place for reflective thinking before and after such time-constrained emergency decisions. More generally, reflective thinking is called for in any aspect of medical practice where there is time and reason for it.

The distinction should be made between the involuntary autonomous nature of System 1 thinking and a deliberate decision to use a shortcut for expediency, which is System 2 thinking. There is normally an override function of System 2 over System 1 but this may be deliberately lifted under extreme conditions.

Future Direction

Critical thinking is a learned process which benefits from teaching and guided practice like any other discipline in health sciences. It was already proposed as part of an early medical curriculum [ 54 ]. If we are to train future generations of health professionals as critical thinkers, we should do so in the spirit of critical thinking as it stands today. Clinical teachers should know how to run a Socratic discourse, and in which situations it is appropriate. They should be aware of contemporary models of argument. Clinical teachers should be trained and experienced in engaging with their interns and residents in meaningful discourse while presenting and discussing morning reports, at floor and other rounds, in morbidity and mortality conferences, or at less informal ‘hallway’, ‘elevator’ or ‘coffee-maker/drinking fountain’ teaching sites for busy clinicians. Such discourse is better than so-called “pimping”, i.e. quizzing of juniors with objectives ranging from knowledge acquisition to embarrassment and humiliation [ 37 , 55 ].

Also, somebody should point out to trainees the relevance to the health context of some basics of informal logic, critical thinking and argumentation, if those basics have been acquired as the result of studying for their first undergraduate degree.

Unquestionably, the appropriate critically appraised best evidence should be used as a foundation for reasoning and argument about how to care for patients. But, if we want to link the best available evidence to a patient’s biology, the patient’s values and preferences, the clinical or community setting, and other circumstances, we should take all these factors into account in using the best available evidence to get to the beliefs and decisions that have the best possible support.

Such a reflective integration cannot be mastered by mere exposure. A learning experience is required. Trainees in medicine need to learn how to think critically [ 56 ], just as they need to learn contemporary approaches to ‘rational’ medical decision making: how to use Bayes’ theorem in the diagnostic process, how to determine the sample size in a clinical trial, how to analyze survival curves in prognosis and outcomes studies, and how to calculate odds ratios in case control research. To understand each other, the teacher and the learner should both know the fundamentals of reasoning and argument in medicine. To achieve this understanding, we can either offer separate and distinct courses on critical thinking and decision making in medicine; or spread learning, practice and experience in critical thinking and decision making across various specialties; or do both. Only the future will show which of the alternatives is better. The integrated approach seems more promising, but harder to implement. Given the limitations on the current medical undergraduate curriculum, we might be hard-pressed to persuade a curriculum committee that precious space and time should be allocated to such concepts. The overriding rationale, however, should be that the knowledge of critical and reflective thinking is declarative knowledge (knowing how) and not simply an addition of procedural knowledge (know-how) or explicit knowledge. The old adage about it being preferable to teach someone how to fish rather than giving them fish applies. Any new additions will need to be streamlined and practical. A teaching module on critical thinking might for example include attention to how we reason and make decisions, factors that may impair decision making, the concept of critical thinking, situations where critical thinking is appropriate, some basic principles of logic and some logical fallacies. However the teaching, learning and practice of critical thinking is incorporated in the medical curriculum, it will need to include not only the contemplative, fully reflective thinking on hospital floors and in clinics but also the shortcut thinking [ 57 ] in such heuristic environments as operating theatres or emergency departments [ 46 , 48 , 58 – 60 ].

Similar education is required as a basis for framing grant applications and research reports as reasoned arguments, especially in the discussion section [ 61 , 62 ]. We may see a day when most medical journals are what Paton [ 63 ] terms “reflective journals”. If an application for a research grant, a research proposal, or a group of research findings (systematically reviewed or not) presented in a medical article are all exercises in argumentation and critical thinking, their authors, readers, and editors should find a common language for all these types of scientific and professional communication.

Almost four decades ago Feinstein [ 64 ] asked what kind of basic science clinical medicine needs. At that time, he had mostly clinical biostatistics and epidemiology in mind. Recently, Redelmeier et al. [ 65 ] proposed to add cognitive psychology as one more basic science. It is time, we think, to add critical thinking to that list.
