  1. How do physical therapists make clinical decisions? Tami Struessel PT, DPT, OCS, MTC

  2. What is Clinical Reasoning?

  3. Expert practice • What does it mean to be an “expert?” • What does it mean to be an “experienced non-expert?” • What makes the expert stand out? • Does anyone here want to be an “experienced non-expert?”

  4. 4 themes that unify philosophy of practice by expert PT’s (Jensen-from commentary by Laurita Hack) • Knowledge-similar to other health professions • Virtue-similar to other health professions • Clinical reasoning • different-PT’s use a more collaborative mode of reasoning that involves patients/families and relies less on a diagnosis of pathology and more on identifying patient goals and function. • Movement • different-PT’s show an exquisite sense of movement, both their own movement as an instrument of patient care and the patient’s movement as a source of information and communication

  6. For you…What does the thought process of an expert look like? • And what DOESN’T is look like?

  7. What is Critical Thinking? • Critical Thinking “typically involves the individual’s ability to do some or all of the following: • Identify central issues and assumptions in an argument • Recognize important relationships • Make correct inferences from data • Deduce conclusions from information or data provided • Interpret whether conclusions are warranted on the basis of the data given • Evaluate evidence or authority “ • (Pascarella and Terenzini, 1991)

  8. What is Critical Thinking? • The thought processes used to evaluate information and the practice of using such conclusions to guide behavior. • The process of critical thinking is associated with accuracy, logic, depth, fairness, credibility, and intellectual clarity. • Critical thinking merely means that one must not automatically accept the validity of the information he or she is given.

  9. What does NOT thinking critically look like? • Blindly thinking that everything you hear is true • Blindly believing everything you read without criticism • Blindly reproducing old learned reactions • Blindly doing the same thing over and over • Can you see these in an “experienced, non-expert”?

  10. What is Critical Thinking? • “Some scholars and educators erroneously assume critical thinking to be higher order thinking or cognitive processing.” (Paul) • “Critical thinking is best understood as the ability of thinkers to take charge of their own thinking. This requires that they develop sound criteria and standards for analyzing and assessing their own thinking and routinely use those criteria and standards to improve its quality.” • Elder and Paul (1994)

  11. Questions for you • How would you rate yourself on your critical thinking skills? • Poor, Fair, Good, Very Good, Excellent? • How would you rate your Critical Thinking skills as you progress through your Physical Therapy education, and practice? • In CEI, did you feel your CI’s demonstrated critical thinking skills? When you asked, were they able to explain why they made the decisions they made?

  12. What is Clinical Reasoning? • Application of Critical Thinking in a clinical context. • The process in which the therapist, interacting with the pt, structures meaning, goals and health management strategies based on clinical data, client choices, professional judgment and knowledge. • Higgs/Jones • What is Wise Action? • Goal of Clinical Reasoning=Wise Action • Davies

  13. Reasoning outside a clinical context(van der Vleuten) • Some times more simple application of knowledge, rules and principles. • For some problems, all data necessary to solve them are present, goals are clear, and solutions are known. Solution is found by technical rationality. • Multiple choice questions assess the ability to solve this sort of problem.

  14. What is Clinical Reasoning? • “Clinical Reasoning is the foundation of professional clinical practice. In the absence of sound clinical reasoning, clinical practice becomes a technical operation requiring direction from a decision maker.” Higgs,Jones • Independent thinking

  15. What is Clinical Reasoning? • In clinical encounters, rarely is all information available. More data must be gathered, and the clinician must deal with contradictory, confusing, imperfect and even inaccurate information. • “The capacity to reason in the context of uncertainty and to solve ill-defined problems is the hallmark of professional competence“ (Johnson, 1988)

  16. Clinical Reasoning by Team? • TEAM: In some contexts, “Clinical Reasoning occurs within a system comprising numerous participants (client/pt, care givers, clinicians, larger healthcare team) all contributing to an understanding of the clinical problem and seeking to implement collaboratively sound, high quality strategies to achieve problem resolution.”

  17. Clinical Reasoning? • Clinicians often face ill-defined problems, goals that are complex and outcomes that are difficult to predict clearly. • Professional judgment and decision-making within the ambiguous or uncertain situations of health care is an inexact science which requires reflective practice and excellent skills in clinical reasoning. Higgs,Jones

  18. The challenge of assessing Clinical Reasoning… • A difficulty with assessment of ill-defined problems as in case situations, is that in similar situations, professionals do not collect exactly the same data and do not follow the same paths of thoughts. • What are the issues with assessing/testing this?

  19. Multiple systems of describing Clinical Reasoning • We’ll use one

  20. Dual Process Theory • Dual process theory based on the interconnectedness of 2 ways the brain reasons: • Croskerry “Overconfidence in Clinical Decision Making.” • System 1 (intuitive) • System 2 (analytical/rational)

  21. “The effortless pattern recognition that characterizes the clinical acumen of the expert physician is made possible by accretion of a vast experience (the repetitive use of a System 2 analytic approach) that eventually allows the process to devolve to an automatic level.” Norman • System 1 (intuition) is the default • Repetitive operations of System 2 (analytical) leads to better System 1 decisions

  22. Dual Process • System 1: Intuitive • Mostly at the subconscious level/ automatic • Pattern recognition • Intuition • More developed in experienced practitioners • Difficult to put into words • Low Scientific Rigor • System 2: Analytical/Rationale • Exhaustive method • Hypothetico-deductive method • Requires knowledge • Easy to put into words • Repetitive use of System 2 leads to better understanding and development of System 1 • Largely forms the basis of the Patient Care Seminar process

  23. Dual Process (Croskerry) • System 1: • Similar to driving a car-no conscious recollection of exactly what you did to get there, but you got there nonetheless.

  24. Dual System Characteristics (Croskerry)

  25. Dual System Characteristics (Croskerry)

  26. Dueling Books that give us thought…

  27. To Think or to Blink? (Malloy, Monash Univ.) • “Decisions made very quickly can be every bit as good as decisions made cautiously and deliberately.” Malcolm Gladwell (Blink) • “That’s all very well if we’re talking about choosing wall paper.” Croskerry 2008 in “Overconfidence in Clinical Decision Making” • Implications of decision making in the health care context

  28. Which system is best? (Croskerry) • It is natural to think that System 2 thinking, coldly logical and analytical, likely is superior to System 1 • but much depends on context. • A series of studies have shown that “pure” System 1 or System 2 thinking (either alone) are error prone; a combination of the 2 is optimal.

  29. Certain contexts do not allow System 1…

  30. In contrast, adopting an analytical approach in an emergent/immediate situation, where rapid decision making is called for, may be paradoxically irrational.

  31. Croskerry • Mark of good decision-maker: • ability to match 2 systems to their respective optimal contexts • consciously blend them into overall decision making.

  32. Holding onto System 1 too tightly • Sometimes people automatically override System 2 and automatically revert to System 1, despite good evidence derived from System 2 that would be preferable.

  33. “Gandhi spoke often of how, at important moments, his “inner voice” would pipe up, with its decisive counsel. His strategy was to make that inner voice “hold its breath” for awhile, to give him time to study the facts. More often than not, the facts bore out what the intuition knew all along.” U-Turn by Grierson

  34. When might bias creep into our decision-making? • Bias-higher risk for error when stakes are high • Affective • Cognitive

  35. Affective biases • Emotions • High stress • Financial stresses • Gender/age biases

  36. Cognitive biases-examples • Confirmation bias – the tendency to search for or interpret information in a way that confirms one's preconceptions • Irrational escalation – the phenomenon where people justify increased investment in a decision, based on the cumulative prior investment, despite new evidence suggesting that the decision was probably wrong.

  37. PT’s are different, and it’s OK • Much of clinical reasoning literature is based on the “diagnosis model” based on physicians. • While we can learn a lot, as PT’s, we think differently…

  38. Specific blended examples of PT decision making using dual approach • Analytical: Hypothetico-deductive approach • Look for “Initial Hypothesis” • Intuitive: • Look for “Pattern Recognition”

  39. What we know about how students use these methods • Analytical (Hypothetico-deducto) and Intuitive (Pattern recognition) have equally poor diagnostic accuracy in novices • Combined strategies improve the accuracy (Eva 2004)

  40. Teaching/learning tips for you • Maximize exposure to a variety of patient conditions in context • You are encouraged to ask: • What is the most likely diagnosis? • What is for and against this diagnosis? • What else could this be? • What is for and against the alternatives? • Recognize distracting stimuli (noise) • Understand and recognize cognitive and affective bias

  41. Teaching/learning tips for you • Identify and analyze and challenge assumptions in arguments • Assess credibility of information (evidence quality) • Understand how to systematically work through a problem • Overtly work on capacity for making effective decisions using both System 1 and 2 • Modeling-Experienced clinicians-see patients, and have them “Unpack” their reasoning

  42. Methods of teaching clinical reasoning • Problem/Case based learning • Compare/contrast decision-making in patients with similar diagnoses • “Consider the opposite” strategies can be an effective de-biasing strategies (avoids over confidence) • The biased fashion in which evidence is generated during the development of a particular belief or hypothesis that leads to overconfidence.

  43. Your goal as you learn to care for patients… • Overtly work on getting better • At the Analytical Process • At Pattern Recognition

  44. PCS • PCS is VERY analytical System 2 • But as you’ve learned, this will help you with the snap/intuitive decisions that are more likely to occur in the clinic
