ABSTRACT
Introduction and Objectives Traditionally at this unit, patients diagnosed with OSA have been initiated on CPAP at a face to face (F2F) appointment. Patients are followed up via telephone consultation at 4 weeks Abstract P23 Figure 1 with a virtual review of CPAP usage. During the Covid-19 pandemic this department adapted their practices to reduce F2F interactions. Patients were sent a CPAP machine via the post and a YouTube video link of how to use the CPAP. The aim of this study is to compare outcomes in symptoms and compliance between the patient groups to evaluate the effectiveness of a postal CPAP service. Methods Patients initiated on CPAP between September and November 2019 (F2F CPAP) were compared to patients initiated on CPAP between April and June 2020 (Postal CPAP). Data was obtained from the electronic records. Patients were only included in the study if all data regarding symptoms, Epworth score and compliance was complete. Results 346 patients were initiated on F2F CPAP between and 185 were sent postal CPAP during the said period. Of these, 191 (55%) and 59 (32%) respectively had full data recorded. Table 1 compares outcomes in symptom improvement and compliance between both groups. Common causes of missing data were unable to contact patient or extended trial. The majority of patients felt their symptoms were better on CPAP. There was no significant difference between the groups in terms of ESS improvement, hours used per night and percentage of nights used. Conclusions Overall, symptom improvement and compliance were similar in both groups. While it is possible that the outcomes were exaggerated as patients who did not respond well or were non-compliant were excluded as they were not contactable, however that is applicable to both groups & hence comparable. This study has huge implications for how the OSA CPAP service is run in future and supports a case that the initiation of CPAP can be done remotely via postal CPAP without impacting on patient outcomes, with fewer hospital visits, PPE use & clinic room utilization. Future studies should look at long term compliance in this group.
