ABSTRACT
Hospitalizations are costly, potentially hazardous for older patients, and sometimes preventable. With Medicare's implementation of hospital penalties for 30-day readmissions on certain index conditions, health care organizations have prioritized addressing those issues that lead to avoidable hospitalizations. Little is known about the utility and feasibility of using standardized tools to identify adults at risk for hospitalizations in primary care. In this study, the goal was to determine, from a sample of 60 adults aged 65 and older, whether the Probability of Repeat Admission (PRA), the Vulnerable Elders Survey (VES-13), or a provider estimate of likelihood of hospitalization could identify patients at high risk for emergency department (ED) visits or hospitalization at 6 and 12 months, while being feasible to administer in a primary care setting. PRA, VES-13, and provider estimate were administered in an outpatient practice. Number of ED visits and hospitalizations at 6 and 12 months were assessed through follow-up phone calls and chart review. PRA and provider estimate were not significant predictors of hospitalizations at 6 months (PRA odds ratio [OR] 1.95; P = 0.39; physician estimate OR 4.33, P = 0.08), but were at 12 months (PRA OR 6.00; P < 0.001; physician estimate OR 2.3; P < 0.05). Additionally, a hospitalization during the prior year was not a significant predictor of hospitalization at 6 months (OR 2.97; P = 0.15) but was at 12 months (OR 3.89, P < 0.05). No tool was a significant predictor of ED visits at either time. PRA and the physician estimate were easy to administer and feasible to implement in a primary care setting.
