Abstract
Objective
The purpose of this study was to examine the impact of increasing allied health staffing levels on patient and health service outcomes across 1) all Geriatric Evaluation and Management patients, and 2) Geriatric Evaluation and Management patients discharged to home in the community.
Design
Quasi-experimental, pre-post intervention study.
Setting
Two sub-acute hospital units in an Australian, tertiary health service.
Subjects
Data related to patients admitted to the study units, who were classified as Geriatric Evaluation and Management patients.
Interventions
Comparison of therapy time across two units with a differential in staffing allocation over a six-month trial period.
Main measures
Primary outcomes: length of stay, readmission rate, and improvement on the Functional Independence Measure. Secondary outcomes: total cost of admission per patient and number of allied health sessions.
Results
Data were analysed for 214 patients (mean age = 79.9, standard deviation (SD) = 9.4 years, mean Functional Independence Measure (FIM = 64.9, SD = 21.2) admitted to the intervention unit, and 199 patients (mean age = 81.3, SD = 8.5, mean FIM = 64.2, SD = 24.0) admitted to the control unit. The overall difference in staffing allocation between the control and intervention units for the trial period was 21%. There was no statistically significant difference between units in subacute length of stay (Adj Coef = -0.10 days, 95%CI = -0.39 to 0.19), rate of readmission (OR = 1.0, 95%CI = 0.5 to 2.0) or change in function (Coef = 1.42 FIM change score, 95%CI = -2.4 to 5.3).
Conclusions
Increasing allied health staffing allocation to a unit over six-months did not impact change in function or length of stay for patients admitted for Geriatric Evaluation and Management.
