The Correlation of Instrumental Activity Daily Living (IADL) Score with Functional Outcome Status and Long-Term Rehospitalization amongst Geriatric Patients

Abstract

: Rehospitalizations amongst geriatric patients are increasing the health care burden. Nonetheless, we have limited information on unplanned long-term rehospitalization. IADL is the more complex functional capacity that usually decreasing before deficits in basic ADL. The aim of this study is to correlate the IADL score before the first admission with functional outcome status and long-term rehospitalization amongst geriatric patients. It is a cross-sectional study. Twenty-one database of geriatric patients with a history of rehospitalization within one-year was included, which set in the geriatric inpatient ward in Cipto Mangunkusumo Hospital. The decline of IADL was measured with Lawton’s score before first hospital admission, the number of rehospitalizations was recorded during history taking, and functional outcome status was assessed with modified Barthel Index (mBI) at discharge. Lower IADL decline before first hospital admission was significantly correlated with higher mBI at rehospitalization discharge (r= -0.647; p= 0.002), but poor correlated with the number of long-term rehospitalization (r = -0.09, p > 0.05). This finding suggests that the independence of ADL at hospital discharge will be achieved if patients have a higher IADL score before admission. Further study needs to be constructed about factors contributing to long-term rehospitalization amongst geriatric patients.
