Do you know when to do CPR?

This is mostly for the PT’s and PT students.  It has been a while since I posted anything, and for that I apologize.  Not an excuse, but our daughter is sick and I don’t have the time to walk away from family for even 20 minutes to read.  This is an old paper that I wrote years ago, while still in the DPT program.  Enjoy and if there are any questions, don’t hesitate to ask.

1.”Historically clinicians have relied on expert opinion, experience, and intuition to determine which evaluative procedures and what interventions to choose.”

2. “Clinical prediction rules may be thought of as the combining of relevant clnical findings to calcularte a numberic probability of the presence of a specific disorder or likelihood of an outcome, ie, they act as adjuncts to the evaluative process”

 

PURPOSE:

1. To describe the potential role of CPR’s in PT practice and to suggest strategies for us to dtermine the appropriateness of using the CPR in daily practice.

 

When are CPR’s needed:

See the other citations as this article would only provide a secondary source for the information. More to come later on the works of McGinn et al and Dellito et al.

 

Proposed use	Type of validity	Method of testing
Screening: prediction the likelihood of the presence of a specific medical or psychobehavioural condition	Criterion-referenced	Prospective, cross-sectional comparison of findings from clinical prediction rule to a “gold standard” that indicates the presence or absence of the condition
Prognosis: predicting the likelihood of a specific outcome	Predictive	Prospective, longitudinal comparison findings from clinical prediction rule to measures of change in patient status over time
Classification into treatment-based groups: predicting the likelihood of outcome when a specific intervention is administered	Prescriptive	Prospective, longitudinal, randomized, controlled design that compares outcomes following different interventions on subjects with the same score on the clinical prediction rule

 

Before using a CPR, the clinician should be aware of the derivation method, the means for internal validity, the statistics (Sn, Sp, +LR) and the population for whom it is expected (external validity)
