The Use of Continuous Positive Airway Ventilation for Patients With Obstructive Sleep Apnea is Associated With Early Medical and Surgery-related Complications Following Total Hip Arthroplasty: A National Database Study.

BACKGROUND

The objective of this study was to determine the effect size of the use of continuous positive airway pressure (CPAP), as a surrogate in cases of active and more severe diseases, on early medical and surgery-related complications following total hip arthroplasty (THA) within an obstructive sleep apnea (OSA) patient population.

METHODS

Patients with OSA who underwent primary THA between 2010 and 2019 were identified using a large national insurance database. Ninety-day incidence of various medical and surgery-related complications and hospital utilization were evaluated for OSA patients who had used CPAP prior to THA and those who did not. Propensity score matching was used to control for patient demographic factors and comorbidities as covariates.

RESULTS

Propensity score matching resulted in 7351 OSA patients who had used CPAP within 6 months of primary THA and 7351 OSA patients who had not. Patients who had used CPAP were at increased 90-day risk of medical complications, as well as 1-year risk of periprosthetic fracture (OR 1.5429; P = .0356), osteolysis (OR 2.4488; P = .0237), aseptic loosening (OR 2.4057; P < .001), and dislocation (OR 1.283; P = .016).

CONCLUSIONS

Our findings suggest that OSA patients on CPAP are at increased risk of several 90-day medical complications, 1-year surgical complications, and health-care utilization compared to OSA patients not recently using CPAP.

LEVEL OF EVIDENCE: III, Retrospective review.
