Medicaid is associated with increased readmission and resource utilization after primary total knee arthroplasty: a propensity score-matched analysis.

ABSTRACT:

Background

Medicaid payer status has been shown to affect resource utilization across multiple medical specialties. There is no large database assessment of Medicaid and resource utilization in primary total knee arthroplasty (TKA), which this study sets out to achieve.

Methods

The Nationwide Readmissions Database was used to identify patients who underwent TKA in 2013 and corresponding "Medicaid" or "non-Medicaid" payer statuses. Demographics, 15 individual comorbidities, readmission rates, length of stay, and direct cost were evaluated.

A chi-square test for paired proportions was used to compare readmission rates between the 2 groups. Length of stay an
