Abstract

Purpose of Study: Surgical readmissions are a concern to the integrity of the Medicare Trust Fund and gaining attention from policymakers concerned about solvency. This study explores factors associated with variation in surgical readmission rates across the states and provides implications for Medicare Case Management.

 

Primary Practice Setting(s): Acute inpatient hospital settings.

 

Methodology and Sample: Fifty state-level data and multivariate regression analysis are used. The dependent variable Surgical Discharge 30-day Readmission Rate is based on the Medicare Fee-For-Service beneficiary population with Medicare Part A and B insurance coverage and age 65 years or older, rehospitalized subsequent to an inpatient surgical procedure, occurring within 30 days of their last discharge.

 

Results: Our 2 key explanatory variables-emergency room visit rate and total days of care-are each positively associated with 30-day surgical readmission rate. Age group 65-69 years, native language, physician density, and health care expenditures per capita also influence surgical readmission rate across the states.

 

Implications for Case Management Practice: Surgical readmission has an association with many different categories of variables-demographic, clinical process, hospital capacity, and patient need. This strongly suggests that Medicare case managers consider the wide range of elements contributing to surgical readmission and take a multifactorial approach to reducing the rehospitalization rate.
