BackgroundIncreased length of stay after total joint arthroplasty has been shown to be a risk factor for peri-operative complications. The purpose of this study was to determine if Medicaid insurance would be a risk factor for increased length of stay after total joint arthroplasty.MethodsWe retrospectively reviewed a single surgeon's practice of 428 total hip and total knee arthroplasties who had insurance status of Medicaid, Medicare, Private or none. After exclusion criteria there were 400 patients. Patients with insurance status of Medicaid, Medicare or Private were then compared based on length of stay ≤ 2 days and length of stay > 2 days and then further analyzed using demographic, operative data, and total length of stay.ResultsMedicaid patients had an increased length of stay compared to patients with Medicare or Private insurance [1.98 days versus 1.73 days, p = .037, 95% confidence intervals (1.78-2.18) and (1.61-1.85), respectively]. The greatest predictor of a less than two-night stay post-operatively was private insurance status (p = 0.001). Medicaid patients had a higher incidence of prescribed narcotic use pre-operatively (p = 0.013). Although not significant, a trend was noted in the Medicaid population with higher incidence of smoking (p = 0.094) and illicit drug abuse (p = 0.099) pre-operatively in this sample subset.ConclusionsPatients with Medicaid insurance undergoing total joint arthroplasty have increased length of stay compared to patients with Medicare or Private insurance and have higher incidence of pre-operative narcotic use.© 2022.
