Abstract

STUDY OBJECTIVES:

To explore the relationship between specific factors such as sex and early continuous positive airway pressure (CPAP) use, and 30-day adherence to CPAP therapy.

DESIGN AND SETTING:

Retrospective study conducted at a single center in southeast Michigan.

PATIENTS:

One hundred patients with obstructive sleep apnea who were recently initiated on CPAP therapy with electronic adherence information relayed from the CPAP device to a laboratory-based computer through telephone modem.

INTERVENTIONS:

N/A.

MEASUREMENTS AND RESULTS:

An empiric threshold value of objective CPAP use of greater than 4 hours per night measured 3 days following CPAP initiation was predictive of level of CPAP adherence measured 30 days later. Furthermore, CPAP adherence was directly proportional to age (R = 0.25, P = .018). There were no sex-related differences in adherence to CPAP therapy.

CONCLUSIONS:

Long-term adherence to CPAP therapy can be predicted as early as 3 days following CPAP initiation. The study also demonstrates that younger age and African-American race are independently associated with lower CPAP adherence.
