Abstract

Abstract : Rationale: Due to the nature and sensation of CPAP, not all patients comply with the treatment. Factors such as age, degree of sleepiness, health status, BMI and sleep apnoea severity may influence CPAP adherence. We sought to determine if these and other factors, particularly socioeconomic status, influence CPAP compliance of our patients. Methods: Demographic data (including age, sex, race and BMI), Epworth Sleepiness Score, Oxygen Desaturation Index (ODI; Desaturations/hour >4% SpO2 ) and prescribed CPAP were retrospectively collected from all patients who had been issued CPAP between 2009 and 2013. In addition, the Index of Multiple Deprivation (IMD) Score and Rank were retrieved from the www.neighbourhood.statistics.gov.uk website. These parameters were then compared between CPAP "compliers" (≥4 hrs/night and ≥4 nights/week) and "non-compliers" (<4 hrs/night or <4 nights/week). Results: We obtained complete data from 407 patients over the four years period. Compliance was achieved in 70.5% of patients. CPAP compliers had significantly worse sleep apnoea (ODI), degree of sleepiness (Epworth) and a higher BMI (Table 1 ); Conclusions: Our data show a good level of compliance compared to previous reports (Shapiro et al . Sleep Breath 2010; 14: 323–25) and patient adherence at 12 months is better than previously reported (Bollig. Respir Care 2010; 55: 1230–9). Although ODI, Epworth and BMI were significantly higher in the CPAP compliers, the differences were only modest. Among the demographics tested, none seem to have a major influence on CPAP compliance in our cohort of patients.
