Association of Insurance Status With Treatment Delays for Pediatric and Adolescent Patients Undergoing Surgery for Patellar Instability

Abstract

Background: Health care disparities have been highlighted in pediatric sports medicine, but the association between insurance status and delayed care for patients undergoing surgery for patellar instability has not been defined. Purpose: To determine whether there is an association between insurance status and delays in care in pediatric and adolescent patients undergoing surgery for patellar instability. Study Design: Cohort study; Level of evidence, 3. Methods: This was a retrospective case series at a safety-net tertiary referral center of pediatric and adolescent patients undergoing surgical treatment for patellar instability. Insurance status was classified as public or private. We calculated the times from injury to clinical evaluation, injury to magnetic resonance imaging (MRI), injury to surgery, clinical evaluation to MRI, and clinical evaluation to surgery. Comparisons were made between insurance groups. Results: Included were 78 patients (38 public, 40 private insurance) who underwent surgery for patellar instability. The public insurance group was older ( P = .019), with a lower proportion of White patients (15.8% vs 52.5%; P = .0005), higher proportion with Hispanic ethnicity (55.3% vs 15.0%; P = .0001), and higher proportion of Spanish-speaking patients (21.1% vs 2.5%; P = .007). Publicly insured patients had longer times from initial injury to clinical evaluation (466 vs 77 days; P = .002), MRI (466 vs 82 days; P = .003), and surgery (695 vs 153 days; P = .0003), as well as a longer time from clinical evaluation to surgery (226 vs 73 days; P = .002). Multivariable models confirmed insurance status as an independent predictor in each of the identified delays. Conclusion: Significant delays were seen for pediatric and adolescent patients with patellar instability and public insurance (approximately 6 times longer to clinical evaluation, more than 5.5 times longer to obtain MRI, and 4.5 times longer to surgery) relative to injured patients with private insurance. Even after adjusting for delays to clinical evaluation, publicly insured patients had a delay from clinic to surgery that was triple that of privately insured patients.
