A mixed method evaluation of a group-based educational programme for CPAP use in patients with obstructive sleep...

Continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) has a low long-term adherence. Educational interventions are few and sparsely described regarding content, pedagogical approach and participants' perceptions. The aim was to describe adherence to CPAP treatment, knowledge about OSA/CPAP, as well as OSA patients' perceptions of participating in a group-based programme using problem-based learning (PBL) for CPAP initiation. EDUCATIONAL PROGRAMME: The PBL programme incorporated elements from theories and models concerning motivation and habits. Tutorial groups consisting of four to eight patients met at six sessions during 6 months.

A sequential explanatory mixed method design was used on 25 strategically selected patients. Quantitative data regarding, clinical variables, OSA severity, CPAP use, and knowledge were collected at baseline, after 2 weeks and 6 months. Qualitative data regarding patients' perceptions of participation were collected after 6 months by semi-structured interviews using a phenomenographic approach.

72% of the patients were adherent to CPAP treatment after 2 weeks and 6 months. All patients improved their baseline knowledge about OSA and CPAP after 2 weeks and sustained it after 6 months. Anxiety and fear, as well as difficulties and needs were motivational factors for participation. Patients described the difficulties of behavioural change, an awareness that improvements do not occur immediately, a realization of the importance of both technical and emotional support and the need for a healthier lifestyle.

A group-based programme using PBL seems to facilitate adaptive and developmental learning and result in acceptable CPAP adherence levels.
