For the first time, a group based cognitive behavioural therapy (CBT) intervention has been demonstrated to markedly increase acceptance and adherence to CPAP treatment for sufferers of obstructive sleep apnea (OSA).
The results of the Australian based study, published this month in the international publication Sleep, found at one month 77% of participants exposed to the intervention used CPAP for a least four hours a night, compared with 31% in the treatment as usual group.
The findings present major positive health implications for sufferers of OSA, with CPAP recognised as a highly efficient treatment for sleep apnea yet low in effectiveness due to reluctance by sufferers to use the device.
The Woolcock Institute of Medical Research successfully conducted the trial in Sydney. One hundred participants were randomly assigned to either a treatment as usual (TAU) group or to the CBT group.
The intervention required participants to attend two one-hour sessions in addition to the usual treatment. It included a 15-minute video presentation featuring real-life CPAP users who described their personal experiences of learning to manage CPAP. The key message was the need to persevere with the treatment and ask for help from the sleep unit staff because of the long-term health benefits. A booklet featuring the same role models accompanied this.
Dr Delwyn Bartlett, Sleep Psychologist at the Woolcock Institute of Medical Research, explains the intervention was designed to help individuals not only understand the risks of OSA but more importantly to see the future benefits of CPAP treatment.
