Key result
A mailed questionnaire successfully identified older Medicaid recipients at high risk for hospitalization, who used hospitals at approximately twice the rate of low-risk subjects (4.5 vs 2.4 days/person-year, P=.009).

Does a mailed questionnaire predicting probability of repeated admission accurately identify older Medicaid recipients at high risk for hospital use?
Absolute Event Rate: 4.5% vs 2.4%
p-value: p=.009
A brief, mailed questionnaire can prospectively identify older Medicaid beneficiaries at high risk for heavy hospital use, allowing for targeted preventive interventions.
Pacala et al. (1995) conducted a cohort in Risk of repeated hospitalization. High-risk classification (Pra ≥ 0.5) via mailed questionnaire vs. Low-risk classification (Pra < 0.5) was evaluated on Actual use of hospitals (days/person-year) (p=.009). A mailed questionnaire successfully identified older Medicaid recipients at high risk for hospitalization, who used hospitals at approximately twice the rate of low-risk subjects (4.5 vs 2.4 days/person-year, P=.009).
