Utility of the Identification of Seniors at Risk score to predict short-term adverse outcomes in elderly patients discharged from a short-stay unit

Objective.

To determine whether the Identification of Seniors at Risk (ISAR) score predicts short-term adverse outcomes in elderly patients discharged from a short-stay unit.

Methods.

Prospective, observational analysis of outcomes in a cohort of all patients 75 years or older who were discharged home from a short-stay unit during a 2-month period. The ISAR score was calculated for each patient. The variable of interest was the development of any adverse outcome (acute severe functional deterioration, death, or

any-cause readmission) within 30 days of discharge.

Results.

One hundred twenty patients (64.2%) with a mean (SD) age of 81.5 (5.4) years were enrolled. An adverse outcome within 30 days of the index event was observed in 36 patients (30%). The ISAR score cut point of 3 had the strongest predictive ability for the composite outcome and for individual components of the composite at 30 days.

Conclusions.

An ISAR score of 3 or higher is able to identify elderly individuals at high risk of an adverse outcome within 30 days of discharge from a short-stay unit.
