1. Be able to define clinical reasoning 2. Understand the complementary roles of deductive and inductive clinical reasoning strategy models 3. Understand and be able to explain the clinical reasoning of expert clinicians compared to novice clinicians 4. Understand and identify errors in clinical reasoning strategies
Who needs treatment and why? What are you treating? How do you know where the pain is coming from? What interventions should be used? What are the expected outcomes of treatment? How should outcomes be measured and documented? What intervention, instructions, services, and number of visits are necessary to meet these outcomes? How should the patient and caregivers be included in the decision-making process? How should the success of the intervention and cost- effectiveness be evaluated? Are referrals needed for other health care services and screenings?
Definitions: Application of relevant knowledge and clinical skills to the evaluation, diagnosis and management of a patient problem - Barrows HS, Feltovich PJ. Med Ed 1987 Cognitive process or thinking used in the evaluation and management of a patient. - Jones, MA Phys Ther 1992 -
A process of reflective inquiry in collaboration with a patient or family seeks to promote a deep and contextually relevant understanding of the clinical problem to provide a sound basis for clinical interventions
Involves the interaction of individuals in a collaborative exchange to achieve mutual understanding of the problem and to negotiate an agreed-upon plan for addressing that problem Is patient centered and situated within a biopsychosocial model of health Involves both deductive and inductive reasoning Is complex, nonlinear, and cyclical in nature Plays a critical role in reflective learning from practice experiences and in the development of clinical expertise
Hypothesis Generation Hypothesis are generated from patient history, signs and symptoms and tested in the examination process Utilizes Pattern Recognition Can be the greatest source of error in thinking-jump to conclusion, ignore needed tests to confirm/counter-dict. Narrative Reasoning Hypothesis regarding patients’ interpretation of their experiences are validated through consensus between therapist and patient Not so much what happens to people but how they interpret it
Dependent upon experience Clinical Personal Didactic Hypothesis formation and testing Confirm or refute hypothesis
Hypothesis Oriented Algorithm for Clinicians HOAC method provides a good algorithm to use for reflection of clinical practice.
Guide for evaluation and interventions, and modification of interventions Logical sequence of activities Independent of treatment philosophies Assists therapists in seeking consultations Means of using evidence in decision making Means to document nature and extent of evidence used
Ideally not linked to an intervention scheme Intervention Schemes: Lack ability to be generalized Deal only with information important to that scheme Contain inherent assumptions of cause based on those schemes but not mechanism for testing outside the scheme
Dynamic relationship between the diagnostic or deductive reasoning process and the narrative inductive reasoning. Using both processes provides a more complete understanding than either alone Using both of these processes together should help to collect and analyze the patient data and tests and measures.
PT must determine the patient goals PT must generate hypotheses concerning cause of dysfunctions PT must determine if the goals have been met PT must determine modifications if goals haven’t been achieved
Interview History Chart review Subjective information What are the patient’s reasons for seeking physical therapy?
51 year old male employed as an electrician Work is mainly installing ceiling light fixtures for several stores in his area Has difficulty working at present Pain in in the right anterior shoulder especially with movement into elevation and depression of GH joint PMH: shoulder impingement and ? Tear of right supraspinatus several years ago; generalized arthritis, bouts of gout since age 28, no exacerbation at present PSH: right rotator cuff surgery one year ago Medications: None
Before doing the actual examination, you would already be establishing goals for the patient Must be functional and measurable Guides the development of goals, put into the problem oriented format What can your patient not do? What would your goals be for this patient? How would you make them functional and measurable?
Not for diagnostic terms and clinical impressions Anticipated problems could be listed here (NPIP) Problems Identified by the Patient (PIP) Functional limitations and disabilities What would be some anticipated problems if this patient didn’t undergo treatment successfully?
PIP’s: patient identified problems Functional limitations Disabilities Therapist needs to generate hypotheses as to problem cause and establish testing criteria NPIP’s: non patient identified problems Problems not identified by the patient May be seen by therapist or reported by family member
Testing criteria established before exam begins Critical values for measurements What will your testing criteria be? Can you list three working hypothesis for this patient?
Independent from treatment goals Collection of objective data Why would you test this? What do you need to know more about?
Mechanisms for testing Has the patient met the goals set? What modifications are needed? Schedule for reexamination should occur When will you see this patient again? How often will you re- evaluate the patient?
Overall approach that will be adopted Only established by the therapist What overall treatment philosophy will you use to treat this patient?
Specific interventions that will be used to meet the strategies Prescribed for a finite period of time What are the specific techniques that will apply to the goals? How much time will you spend on interventions?
Implementation of program May be implemented by a number of different people, not just the PT Who will do what when?
Goals met Criteria for discharge Modification of interventions Did your treatment interventions allow this patient to achieve her goals?
Strategy correct? Hypothesis viable? New hypothesis and strategy necessary? Will you have to change your strategy? Your hypothesis? How will you know change is necessary?
Conceptual scheme Generate hypothesis prior to seeing the patient Generate testing criteria Develop rational for physical therapy intervention Develop goals, outcomes, prognosis Set Criteria for re-evaluation
The cognitive processes used in the evaluation and management of a patient Application of relevant knowledge and clinical skills to the evaluation, diagnosis and management of a patient problem (Barrows and Feltovich, 1987)
Steps taken by a clinician to reach physical therapy diagnosis and management (intervention) decisions HOAC method may be utilized here ? How does the physical therapy diagnosis used in clinical reasoning differ from the hypothesis development in the HOAC method?
Stage One: accumulation of biomedical, basic scientific knowledge Knowledge is linked in a network presented through formal education Clinical reasoning is based on biomedical concepts Students have difficulty differentiating between relevant and irrelevant patient findings – excessive hypothesis develop
Integration of biomedical knowledge into clinical knowledge Occurs with increase experience with patients Links are formed between patient findings and clinical concepts Hypothesis formation is more refined
“illness scripts” begin to develop Clinical patterns plus the information on predisposing factors, medical hereditary conditions, patho-physiological process that occurs, presenting signs and symptoms Increases efficiency of knowledge network, search less for information
Content and structure involved in the storage of clinical encounters as “instant scripts” in memory Stored separately from the clinical knowledge Recognize variations of the “instant scripts” of basic clinical patterns seen in practice Jones M (1994) Clinical Reasoning in Orthopedic Manual Therapy in Physical Therapy of the Cervical and Thoracic Spine, 2nd ed.

Hypothesis Oriented HOAC method provides a good algorithm to use for reflection of clinical practice.
Framing Errors: Forming a wrong initial concept of the problem Failure to generate plausible hypothesis Inadequate testing of hypothesis Premature acceptance of the hypothesis Failure to attend to features that are missing Over-emphasis on features which support the “favorite” hypothesis
Tendency to look for, notice, and remember information that fits with our pre-existing expectations. Competing hypothesis aren’t tested
Overreliance on outcome information to indicate the accuracy or quality of the clinical reasoning that occurred when the interventions were chosen Good outcome = good clinical reasoning Poor outcome = ?, situation outside PT control
Develop an awareness of cognitive processer or reasoning used to come to clinical decisions Understand common clinical reasoning errors Try to understand why your reasoning might be wrong Always include in the exam questions, physical screening and tests and measures that would disprove your hypothesis Develop a knowledge of prevalence and incidence of various conditions, make sure you don’t jump to pattern recognition too soon.
