Abstract

OBJECTIVES:

To study the effects of augmentation of continuous positive airway pressure (CPAP) education and support on compliance and outcome in patients with obstructive sleep apnea (OSA).

DESIGN:

A randomized, controlled, parallel study of basic vs augmented CPAP education and support.

SETTING:

A university teaching hospital.

PATIENTS:

A total of 108 OSA patients randomized into basic-support (BS) and augmented-support (AS) groups.

INTERVENTIONS:

Patients in the BS group (n = 54) were given educational brochures on OSA and CPAP, CPAP education by nurses, CPAP acclimatization, and were reviewed by physicians and nurses at weeks 4 and 12. Patients in the AS group (n = 54) received more education, including a videotape, telephone support by nurses, and early review at weeks 1 and 2.

MEASUREMENTS:

Objective CPAP compliance, Calgary sleep apnea quality of life index (SAQLI), and cognitive function after 1 month and 3 months; and Epworth sleepiness scale (ESS) after 3 months of CPAP treatment.

RESULTS:

At 4 weeks, CPAP usage was 5.3 +/- 0.2 h/night (mean +/- SEM) vs 5.5 +/- 0.2 h/night in the BS and AS groups, respectively (p = 0.4). At 12 weeks, CPAP usage was 5.3 +/- 0.3 h/night vs 5.3 +/- 0.2 h/night in the two groups, respectively (p = 0.98). There was greater improvement of SAQLI at 4 weeks (p = 0.008) and at 12 weeks (p = 0.047) in the AS group. There was no significant difference between BS and AS groups in terms of improvement of ESS and cognitive function.

CONCLUSION:

Augmentation of CPAP education and support does not increase CPAP compliance, but leads to a greater improvement of quality of life during the reinforced period.
