ABSTRACT
STUDY OBJECTIVES: Chronic noncancer pain (CP) commonly co-occurs with obstructive sleep apnea (OSA) and may contribute to greater symptom burden. The study aims were to (1) characterize CP among veterans with OSA; and (2) examine differences in sleepiness (Epworth Sleepiness Scale, ESS), insomnia symptoms (Insomnia Severity Index [ISI]), and quality of life (Short Form Health Survey 20, SF-20) in veterans with OSA with or without pre-existing CP.
METHODS: An observational, cross-sectional, study of 111 veterans with newly diagnosed, untreated OSA was conducted. Descriptive statistics characterized the sample and comorbid CP outcomes. Regression analyses were performed to investigate associations between self-reported CP and sleep-related symptoms or quality of life while controlling for potential confounders.
RESULTS: CP was reported by 69.5% (95% CI: 61.8, 76.2) of participants. Having CP was associated with increased ESS (12.7 ± 5.5 vs 10.2 ± 5.2; p = 0.021) and ISI scores (18.1 ± 6.2 vs. 13.7 ± 7.4; p = 0.002), and worse quality of life across all SF-20 domains.
CONCLUSIONS: There is a high prevalence of CP among veterans with OSA and symptom burden is higher in patients with OSA and CP. Future investigations should address symptom response and burden to OSA treatment in comorbid OSA and CP to guide outcome expectancies and residual OSA symptom treatment plans.
