Abstract

PURPOSE: To explore affects of behavioral/psychological variables on compliance with CPAP therapy.

METHODS: Patients suspected of having OSA had polysomnogram (PSG) or split-night PSG. Some returned for CPAP prescription study. They completed questionnaires addressing behavioral variables hypothesized related to future compliance with CPAP before and after PSGs. Those with OSA prescribed CPAP completed questionnaire addressing CPAP usage and problems encountered at first follow-up visit. Compliance was determined using meter in CPAP unit which calculated hours use per night mask on. Average of 4hrs/night defined compliance with CPAP.

RESULTS: Groups 1 and 2: CPAP compliant (n=19). Non-compliant including those who discontinued CPAP (n=19). Univariate logistic regression: noncompliant were more likely to have had a recent death in family (p=0.044). Mann-Whitney U-test: compliant group more likely reported feeling better after using CPAP for first time during sleep study (p=0.019). Fischer's exact test: non-compliant group more likely reported CPAP uncomfortable because mask was tight (p=0.018) and compliant group more likely reported CPAP easy to use first time during sleep study (p=0.036). There was no statistically significant difference among 2 groups regarding history of medication non-compliance, marital status, recent hospitalization, recent life-changing events, punctuality at work or medical appointments, importance placed on yearly medical check-ups, exercise and diet habits. There was no significant difference among the 2 groups regarding level of alertness, willingness to use CPAP daily or recommend CPAP to others, awareness of physical benefits of CPAP, or knowing other people who have used CPAP and have struggled with it.

CONCLUSION: There is a positive correlation between compliance with CPAP therapy and the level of comfort and ease of use on first night using CPAP and feeling better the next day. A recent death in the family appears to have an adverse affect on compliance.

CLINICAL IMPLICATIONS: Identifying patients at higher risk of being non-compliant with CPAP is feasible and important so that they can be followed more closely and interventions to improve compliance can be offered at an earlier stage.
