Objectives: To determine the frequency of poor patient participation during inpatient physical (PT) and occupational therapy (OT) sessions and to examine the influence of poor participation on functional outcome and length of stay (LOS).
Design: Prospective observational study.
Setting: University-based, freestanding acute rehabilitation hospital.
Participants: Two hundred forty-two inpatients, primarily elderly (age range, 20-96y), with a variety of impairment diagnoses (eg, stroke), who were admitted for inpatient rehabilitation.
Interventions: Not applicable.
Main outcome measures: The Pittsburgh Rehabilitation Participation Scale, the 13 motor items from the FIM instrument (FIM motor), LOS, and discharge disposition.
Results: We categorized the sample into 3 groups: "good" participators were those for whom all inpatient PT and OT sessions were rated 4 or greater (n=139), "occasional poor" participators were those with less than 25% of scores rated below 4 (n=53), and "frequent poor" participators were those with 25% or more of scores rated below 4 (n=50). Change in FIM motor scores during the inpatient rehabilitation stay was significantly better for good and occasional poor participators, compared with frequent poor participators (mean FIM improvement: 23.2, 22.8, and 17.6, respectively; repeated-measures analysis of variance group by time interaction, P <.002). LOS was significantly longer for occasional poor participators, compared with good and frequent poor participators controlling for admission FIM differences (adjusted means: 13.9d, 11.0d, and 10.9d, respectively; analysis of covariance, P <.001).
Conclusions: Poor participation in therapy is common during inpatient rehabilitation and has important clinical implications, in terms of lower improvement in FIM scores and longer LOS. These results suggest that poor inpatient rehabilitation participation and its antecedents deserve further attention.
