Barriers to positive airway pressure adherence among veterans with sleep apnea: a mixed methods study
TRANSLATIONAL BEHAVIORAL MEDICINE(2022)
摘要
Lay Summary Positive airway pressure (PAP) is an effective treatment for sleep apnea, but many patients have trouble tolerating it. We interviewed 30 veterans at a Department of Veterans Affairs Medical Center who do not use their PAP every day. We interviewed them to identify the most common barriers to use. We also reviewed their medical records to investigate whether other factors, such as the severity of their apnea or their daytime sleepiness, were associated with number of hours of PAP use. In addition, we asked patients what their providers recommended to improve their PAP adherence. We categorized all reported barriers to PAP use into four main groups: physical, psychological, situational, and knowledge. Physical problems and psychological barriers were most commonly reported and were endorsed at approximately equal rates. None of the factors reviewed during chart review were associated with the number of hours PAP was used. The most common solution providers recommended was trying a different mask. Providers rarely suggested solutions to psychological barriers, such as insomnia or claustrophobia. We recommend that sleep medicine clinics involve behavioral health providers in sleep apnea care to help address psychological barriers to PAP use. Rates of adherence to positive airway pressure (PAP) for sleep apnea are suboptimal. Though previous studies have identified individual factors associated with PAP nonadherence, few projects have investigated a wide range of possible barriers directly from the patient perspective. We examined the range of factors that patients identify as barriers to optimal use of PAP as well as the solutions most commonly offered by providers. We employed a mixed methods design including semistructured interviews and medical record review at a US Department of Veterans Affairs Medical Center. Thirty patients identified as nonadherent to PAP participated. Patients were asked to report on current sleep problems, reasons for nonadherence, and solutions proposed by providers. Chart review was used to identify untreated apnea severity, Epworth Sleepiness Scale score, therapy hours, and residual apnea severity. Patients described physical and psychological barriers to adherent use at approximately equal rates: Mask leaks and dry throat/nose were common physical barriers, and anxiety/claustrophobia and worsening insomnia were common psychological barriers. Untreated apnea severity, residual apnea severity, and daytime sleepiness were not associated with therapy hours. Solutions offered by providers most frequently addressed physical barriers, and solutions to psychological barriers were rarely proposed. The most common solution offered by providers was trying different masks. We recommend individualized assessment of each patient's barriers to use as well as increased involvement of behavioral health providers in sleep medicine clinics.
