An analysis of the relationship between the utilization of physical therapy services and outcomes of care for patients after total hip arthroplasty.
OBJECTIVE
The effect of physical therapy intervention on the outcomes of care for patients treated in acute care hospitals has not been widely studied. This study examined the relationship between physical therapy utilization and outcomes of care for patients following total hip arthroplasty.


METHODS
The sample consisted of 7,495 patients treated in US academic health center hospitals in 1996 who survived their inpatient stay and received physical therapy interventions.


METHODS
The primary data source was the University HealthSystem Consortium Clinical Data Base. Physical therapy use was assessed by examining physical therapy charges. Outcomes of care were assessed in terms of the total cost of care (ie, whether the care was more costly or less costly than expected, taking into account patient characteristics) and in terms of discharge destination (ie, whether the patient was discharged home or elsewhere). Regression analyses were conducted to examine the relationship between physical therapy use and outcomes.


RESULTS
Physical therapy intervention was directly related to a total cost of care that was less than expected and to an increased probability of discharge home.


CONCLUSIONS
The results of this study provide preliminary evidence to support the use of physical therapy intervention in the acute care of patients following total hip arthroplasty and indicate the need for further study of this topic.
