actice (e.g. Assessment , Examination Evaluation, & outcome measurements ). Physical Therapist Patient/Client Management Model The physical therapist int egrates the five elements of patient/client manage ment in a manner design ed to optimize outcomes. Examinatio n, Outcome Evaluation,

Interventio n Diagnosis, (The Interactive Guide to Physical Therapist P ractice with Catalog of Tests and Measures (20 02) Prognosis, Assessment Assessment is the overall process of selecting and using multiple data-collection tools and various sources of information Outcome measurements It involves interpreting information

collected to make clinical decisions (analysis and synthesis) related to the needs of the person and the appropriateness & nature of their therapy. Evaluation Examinati on Assessme nt Examination Comprehensive screening and specific testing process leading to identifying potential and existing movement-related disorders, diagnostic classification and/or, as appropriate, to a referral to another practitioner Component of examination

History Systems review Tests & measures Evaluation Evaluation is a component of assessment process Evaluation is based on the data gathered from the examination(e.g. history, systems review, and tests and measures) and synthesizes all of these findings to establish the diagnosis, prognosis, and plan of care. Evaluation involves the collection of data to enable the therapist to make a judgment about the amount of a specific construct of interest Measurement measurement

A measurement is the data obtained by measuring. A measurement is obtained by applying a standard scale/tools/equipment to variables, thus translating direct observations or client/proxy reports to a numerical scoring system. Health Outcome Measurements A health outcome is a chan ge in the health of an indivi dual, or a group of people o r population, which is wholl y or partially attributable to an intervention or series of i nterventions. (AHMAC Febr uary 1993; Modified by NHI MG 1996) Health Outcomes Framework

Outcome measurement Outcome measurement is a process undertaken to establish the effect s of an intervention on an individual or the effectiveness of a service on a defined aspect of the health or well-being of a specified population OUTCOMES Outcomes Assessment Collection and recording of information rel ative to health processes Outcomes Management Using information in a way that enhances patient care Primary versus Secondary OM Outcomes

Primary Variable providing the most relevant and convincing evidence related to the main objective of the research. Secondar y Supportive measurements of the primary objective or

measurements of effects related to other secondary objectives. Generic versus Specific OMs Generic Diseases-specific Purpose Assess overall health status across a broad spectrum of norms /and or diseases Gather information about the impact of a specific health condition Population

General population (healthy and non-healthy) Applicable across individuals with differing condition health conditions Used for patients with a specific health Benefit Allow comparison to normative populations More sensitive & provides insight into the relationships among body function/structure impairments, activity limitations, and participation

Limitation Ceiling and floor effects more likely Does not allow comparisons across different groups of patients Example Functional Independence Measure Clinical indicators and physiological measures Patient-reported disease specific measures Performance-Based Measures versus Self-report OMs Self report

Performance based Purpose Assess actual performance in a particular environment at a specific point in time Collect information on patients opinions/ perceptions of the impact of the health condition Determine current level of function Data collection Methods Timing, distance, force , power , strength, Observation of performance

Rating level of independence/difficulty Interview Questionnaire Benefit Allows observation of task performance Less likely to have missing data Can assess constructs not observed during performance (e.g., fear of falling) Can assess activities not observed clinically Limitation Equipment required, environmental factors, fatigue, motivation, and learning effects,

measure inaccuracy Cognitive and communication ability Language and educational level Patient may miss or misinterpret items or over-/underestimate ability Example Functional Independence Measure , Gross motor function measure 10-meter walking test, Time up and go test 36-short form health questionnaire Seattle Angina Questionnaire (SAQ) Child Health Questionnaire (CHQ)

Patient-reported outcomes (PROs) A PRO is any report of the status of a patients health condition that comes directly from the patient, without interpretation of the patients response by a clinician or anyone else.
