MedicalResearch.com: What are the main findings of the study?
Prof. Kaestner: Gaining prescription drug insurance through Medicare Part D was associated with a 8% reduction in the probability of a hospital admission, a 7% reduction in Medicare payments for inpatient services per person (who obtained insurance), and a 12% reduction in hospital resource use per person.
MedicalResearch.com: What should clinicians and patients take away from your report?
Prof. Kaestner: Prescription drugs are, on average, a substitute for inpatient care.
The greater use of prescription drugs that comes with insurance prevents hospitalizations.
MedicalResearch.com What recommendations do you have for future research as a result of this study?
Prof. Kaestner: Future research should try to identify the specific biological and clinical mechanisms underlying the finding that prescription drug use decreased hospitalization.
