Prognostic Flashcards
Prognosis is
the process of predicting the future of a patients condition
Prognosis in PT is used to
identify risk of developing a problem
predict ultimate outcome of impairments
predict results of PT interventions
T/F
Identification of risk factors to avoid a future event are part of prognosis
True
Its formulate a prognosis based on ultimate outcome of:
movement-related impairments
functional limitations
participation restrictions
Ultimate outcomes provide a context for the therapist to
formulate plan of care
determine treatment related prognosis
Prognoses about treatment responses are subsets of
the prediction of ultimate outcomes
Prognostic factors vs. Risk factors
Prognostic - patient characteristics that may predict future outcome
Risk - predictors of future adverse effects
What does prognostic research use to identify prognostic factors
descriptive stats and tests of relationships
Tests of relationships related to prognosis - simple relationship
Pearsons r
Spearmans p
chi square
Simple use to determine if further investigation is needed
Tests of relationship related to prognosis - complicated rellationship
Regression analysis - can be used to predict
Odds ratio - the odds that an individual with a prognostic factor had an outcome od interest as compared to the odds for an individual without the prognostic factor
Statistical importance of study results
Meaningfulness or potential importance of the study results are conveyed using p values and confidence intervals
P value
indicated the probability that the result obtained occurred due to chance
The smaller, the more significant
True or False: Evidence about prognostic factors relevant to PT are limited
True
Use of available prognostic factor must be considered with
verification of validity
importance
Relevance of the available evidence
Was the defined sample of patients assembled at a common point in the course of their disease
