Opioids increase the risk for sleep disordered breathing (SDB), but there are few studies examining the prevalence and risk factors for SDB, specifically central sleep apnea (CSA), and obstructive sleep apnea (OSA) in chronic pain patients on opioids as well as methadone maintained patients (MMPs). ⋯ CSA and OSA are common in MMPs and chronic pain patients on opioids. Among chronic pain patients, higher opioid doses appear to be a risk factor for CSA, and to a lesser extent OSA. Therefore, it is important for providers to screen these patient populations for SDB.
