Abstract

Background: Positive airway pressure therapy is mainstay of treatment of obstructive sleep apnea (OSA). But long-term compliance with is poor with such therapy. A proactive and vigilant management may improve the PAP therapy usage. Cloud-based telemonitoring PAP devices offer an opportunity for proactive monitoring and prompt interventions related to PAP troubleshooting. This technology is also used in India for adult OSA patients. But we lack our own data on behavior of Indian patients as a cohort on PAP therapy. The present study is an attempt to look at the behavior a cohort of PAP users in OSA.

Methodology: This study was planned as a retrospective analysis of data of OSA patients who were using a cloud-based PAP devices. First 100 patients were chosen for data retrieval that who was on this therapy. The data was obtained for those patients who were on PAP for at least 7 days and maximum follow-up was available up to 390 days. Descriptive statistical analysis has been carried out in the present study.

Results: The number of male and female patients was 75 and 25, respectively. Overall good compliance was present in 66% of patients. 34% of patients were not compliant with PAP during follow-up. The compliance was statistically same in both the sexes (P = 0.8088). Incomplete data recovery was present in 17 patients and 11 (64.70%) were non-compliant among them. In the initial, 60 days non-compliant patients were more than compliant patients. The difference was lost in 60 to 90 days of use. The air leak was present more in the compliant group than non-compliant group (P = 0.0239). 75.75% of compliant patients had achieved AHI control, whereas 35.29% of non-compliant patients also achieved AHI control. But overall, AHI control was poor in non-compliant patients and 61.76% of non-compliant patients had an AHI uncontrolled.

Conclusions: We conclude that 3/4th of the compliant patients achieve AHI control while 1/4th didn't. This 1/4th population needs further exploration to determine the causes of poor AHI control. Cloud-based PAP devices give an easy opportunity to monitor patients of OSA. It gives an instant panoramic view of behavior of OSA patients on PAP therapy. The compliant patients can be tracked, and non-compliant patients can be segregated quickly.
