Abstract
Introduction
Previous studies have reported an increased risk for postoperative complications in the Medicaid population undergoing total hip arthroplasty (THA). These studies have focused on payer type and have not controlled for the surgeon's practice or patient care setting. This study aims to evaluate whether patient point of entry plays a role in quality outcomes and discharge disposition following THA.
Methods
The electronic medical record at our institution was retrospectively reviewed for all primary, elective, unilateral THA between January 2016 and June 2018. THA recipients were categorized as either Hospital Ambulatory Clinic Centers (HACC) with Medicaid as the primary payer or private office patients with a non-Medicaid primary payer based on a previous visit to our institution's HACC within the 6-months prior to surgery. Only patients who had been operated on by a surgeon with at least 10 HACC and 10 private office patients were included.
Results
A total of 426 patients were included in this study, with 114 HACC and 312 private office patients. HACC patients were significantly younger (p<0.01), more likely to be black or “other” race (p<0.01), and more likely to be a current smoker (p<0.01). In the unadjusted model, length of stay (p=0.15) and surgical time (p=0.03) were greater in HACC patients. There was no difference in discharge disposition (p=1). After adjusting for patient risk factors, LOS was greater for HACC patients, whereas surgical time and facility discharge were lower.
Conclusion
There was a significant difference in surgical time between HACC and private clinic patients. After controlling for patient risk factors, LOS, surgical time, and facility discharge were similar between the two groups. These results indicate that similar outcomes can be achieved for Medicaid patients as compared to non-Medicaid patients as long as the surgeon and patient care setting are similar.
