Abstract

OBJECTIVE/BACKGROUND

Home blood pressure monitoring (HBPM) has become the standard of care for diagnosing hypertension - the most prevalent comorbidity of obstructive sleep apnea (OSA) - and for monitoring blood pressure response to treatment. Connected devices have been used in recent studies to monitor blood pressure in patients with OSA initiated on continuous positive airway pressure (CPAP). We compared the respective evolution of HBPM completion rate and CPAP adherence rate in the first six months of treatment.

PATIENTS/METHODS

98 patients were prospectively included, and were asked to record 6 daily HBPM measurements. CPAP adherence was obtained using telemonitoring. HBPM completion rates and CPAP adherence rates were monthly calculated. A Mann- Kendall test was performed to describe the changes in rates and adjusted linear mixed models were used to assess the association between these two rates.

RESULTS

HBPM completion rate significantly decreased from 44% during the 1st month to 19% at six months. CPAP adherence rate significantly increased from 35% the 1st month to 41% at six months. A similar decrease of HBPM completion rate was shown among different patients' profiles. Linear mixed models showed that an increase in CPAP adherence rates of 1% was associated with an increase in HBPM completion rates of 0.17% [0.08; 0.25].

CONCLUSION

The use of HBPM device decreased regardless the patients' clinical phenotype, whereas adherence to CPAP increased slightly. The positive association between the two rates was modest and non-clinically significant suggesting a limited interaction between the use of the two connected devices.
