Abstract
To evaluate the Siebens Domain Management Model (SDMM) for geriatric inpatient rehabilitation (IR) to increase functional independence and dispositions to home.
Before and after study.
IR facility.
During 2010 (preintervention), 429 patients aged ≥75 years who were on average admitted to IR 8.2 days postacute care, and during 2012 (postintervention), 524 patients aged ≥75 years who were on average admitted to IR 5.5 days postacute care. Case-mix group (CMG) comorbidity tier severity, preadmission living setting, and living support were similar in both groups.
The SDMM involving weekly adjustments of IR care focused on potential barriers to discharge home.
FIM efficiency, length of stay (LOS), and disposition rates to community/home, acute care, and long-term care (LTC) to compare pre-/postintervention facility data and comparison of facility to national CMG-adjusted data from the Uniform Data System for Medical Rehabilitation for both years (2010/2012).
Pre-/postintervention group admission FIM scores were similar (t=2.96, P<.003), but the preintervention group had on average 2.6 days greater LOS during IR and greater time to onset of IR (8.2 vs 5.5d) from acute care. Preintervention FIM efficiency was 2.1, whereas postintervention FIM efficiency was 2.76, a significant difference (t=4.1, P<.0001). There were significantly more discharges to the community in the postintervention group (74.4%) than the preintervention group (58.5%, χ(2)=26.2, P<.0001). There were significantly fewer patients discharged to LTC in the postintervention group (χ(2)=30.47, P<.0001). The preintervention group did not significantly differ from the 2010 national data, but the postintervention group significantly differed from the 2012 national data for both greater FIM efficiency (t=-5.5, P<.0001) and greater discharge to community (χ(2)=34, P<.0001). LOS decreased by 2.6 days in the postintervention group compared with the preintervention group, whereas LOS decreased by only 0.6 days nationally from 2010 to 2012, a significant difference with postintervention LOS lower than the national data (t=31.1, P<.0001).
Use of the SDMM during IR in geriatric patients is associated with increased functional independence and discharges to home/community and reduced institutionalization.
