PURPOSE: To utilize a nationwide administrative database (PearlDiver) to investigate if patients with general anxiety disorder (GAD) undergoing primary hip arthroscopy for femoral acetabular impingement syndrome (FAIS) have higher rates of: 1) medical complications
2) readmission rates
and 3) costs of care, as compared to patients without GAD. METHODS: Using the PearlDiver database, a retrospective query from January 1 RESULTS: The query yielded 7,631 patients with GAD undergoing hip arthroscopy for FAIS. These patients were compared to 38,145 matched controls without GAD. Patients with anxiety were at significantly higher risk for post-surgical complications, with the highest risks observed for pneumonia (1.0% vs 0.4%
OR 2.57, 95% CI: 1.97 - 3.35, p = 0.004) and deep vein thrombosis (DVT) (0.36% vs 0.15%
OR 2.42, 95% CI: 1.52 - 3.76, p = 0.002). Other significant risks included acute renal failure (0.46% vs 0.21%
OR 2.13 95%CI: 1.42 - 3.15, p = 0.002) and pulmonary embolism (0.21% vs 0.13%
OR 1.66, 95%CI: 0.92 - 2.87, p = 0.001). There was no statistical difference in readmission within 90-days (1.46% vs 1.24%
OR 2.38, 95% CI: 2.13 - 2.67, p = 0.02) or 90 day total cost of care between the two groups (,812 +/- 1,292 vs 4,076 +/- 1,179, p = 0.73). CONCLUSION: After adjusting for age, sex, and medical comorbidities
this study found GAD was associated with a significantly higher rate of pneumonia, DVT, acute renal failure, and PE following hip arthroscopy for FAIS. There were no significant differences in 90-day readmissions rates or 90-day total cost of care. Considering the relatively high prevalence of anxiety and the increasing rate of hip arthroscopy, preoperative screening for anxiety may help surgeons identify and protect patients at increased risk of complications after hip arthroscopy LEVEL OF EVIDENCE: III
