      Abstract

      Objective

      To investigate whether a direct measure of need for PT, mobility status, was associated with acute care PT utilization and whether this relationship differs across sociodemographic factors and insurance type.

      Design

      In a secondary analysis of electronic health records data, we estimated logistic regression models to determine whether mobility status was associated with acute care PT utilization. Interactions between mobility and both sociodemographic factors (sex; age; significant other; minority status) and insurance type were included to investigate whether the relationship between mobility and PT utilization varied across patient characteristics.

      Setting

      Five regional hospitals from one health system.

      Participants

      60,459 adults admitted between 2014 and 2018 who received a PT evaluation.

      Interventions

      None.

      Main Outcome Measure(s)

      Received acute care PT; Activity Measure for Post-Acute Care (AM-PAC) “6-Clicks” measure of mobility.

      Results

      Half of patients who received a PT evaluation received subsequent treatment. Patients with mobility limitations were more likely to receive PT. Interaction terms indicated that among patients with mobility limitations, those who 1) were younger; 2) had significant others; and 3) had private insurance (vs. public) were more likely to receive PT. Among patients with greater mobility status, older patients and those without a significant other were more likely to receive PT.

      Conclusions

      The relationship between acute care PT need and utilization differed across sociodemographic factors and insurance type. We offer potential explanations for these findings to guide studies targeting equitable distribution of beneficial PT services.
