0530 A Study of Pediatric PAP Compliance in Longitudinal and Single-Visit Patients

Abstract

Abstract Introduction PAP compliance is difficult to attain and maintain, but important for treatment efficacy in obstructive sleep apnea. This study sought to identify patterns of compliance by age, stratified by gender and device type in patients who followed up only once after treatment initiation (single-visit patients) and those who were seen more than once (longitudinal patients). Methods Charts for approximately 10 months from 10/2018 to 7/2019 were retrospectively reviewed for 1177 patient visits, representing 521 patients with 246 single-visit and 275 longitudinal patients. Some longitudinal patients had visits dating back to 2002. Data analyzed included: age at visit versus compliance measured by percentage of days used and percentage of days used over 4 hours during their compliance period. Data was analyzed for single visit and longitudinal patients stratified by gender and device type. Age was categorized as 0 to 24 months, then years 3.0 to 5.9, 6.0 to 12.9, 13.0 to 18.9 and 19.0 to 21.9. Results Patient demographics: 47.2% single-visit, 52.8% longitudinal; 60% male; Approximately 80% between 6 and 18.9-years-old; 80.8% used CPAP. Statistically significant results:Seen for different age groups among females (p=0.012): Females 19 to 21.9-years-old had 45.8% lower compliance for percentage of days used over 4 hours compared to 3 to 18.9-years-old.Longitudinal patients showed 7.5% and 2.4% better compliance for percentage of days used (p=0.0006) and for days used over 4 hours (p=0.002), respectively, compared to single-visit patients after adjusting for sex and age group. Using a BPAP device was associated with 8.9% better compliance for use over 4 hours (p=0.002) compared to CPAP after adjusting for sex, age and visit groups. Longitudinal patients had 7.7% higher compliance for % days used over 4 hours compared to single visit patients (p=0.0016) after adjusting for sex, age group and device. Conclusion Statistically significant positive factors for compliance were longitudinal patients versus single-visit patients and those using BPAP.Among females, 19 to 21.9-year-olds were least compliant, otherwise no differences between age or gender were identified.
