Compliance with CPAP treatment in patients with obstructive sleep apneas during the COVID-19 pandemic in two hospitals in the Federal Capital ; Cumplimiento del tratamiento con CPAP en pacientes con apneas obstructivas del sueño durante la pandemia COVID-19 en dos hospitales de Capital Federal ; Adesao ao tratamento CPAP em pacientes com apneia obstrutiva do sono durante a pandemia COVID-19 em dois hospitais da Capital Federal

Introduction: CPAP therapy is the first line treatment for sleep apnea and its effectiveness depends on adherence. Face to face control and follow-up was limited due to the fact that our country was immersed in social isolation due to the COVID-19 pandemic as of March 2020. In order to assess whether CPAP adherence was maintained in patients with obstructive sleep apnea (OSA), in two hospitals during the COVID-19 pandemic and compare it with the pre-pandemic situation on a historical control basis in the city of Buenos Aires. Methods: Observational and retrospective study based on systematic data collection of adherence to CPAP and residual apnea-hypopnea index (AHI). For comparison, a historical control corresponding to the specular period (May to December of each year between 2016 and 2019) was used as a reference. Patients over 18 years ago with OSA on CPAP therapy more than 30 days of treatment were included. Patients with other chronic respiratory diseases requiring ventilation therapy (Bi-level, servo ventilation, volume-assured ventilation) were excluded. Results: 151 pre-pandemic patients and 127 from the pandemic period, respectively, were evaluated. Men 98 (65%) vs. 50 (60.3%) p: 0.9, age: 65.4 ± 11.9 vs. 63.6 ± 12.6 p: 0.22, body mass index 31.5 ± 5.0 vs. 31.2 ± 5.3 kg/m2 p: 0.6, respectively. In both centers, the most used treatment was fixed CPAP; 90 (59.6%) vs. 96 (75.6%) p: 0.005. There was an increase in compliance with it compared to the pre-pandemic period in minutes/night [341.4 95% CI 292.4 - 340.6 vs. 274.3 95% CI 208.5 - 267.4, p: 0.001] and residual AHI reduction [3.3 IC 95% 2.0 - 3.05 vs. 6.3 IC 95% 2.6 - 4.3 p: 0.006]. Conclusions: In the period of the COVID-19 pandemic, greater adherence to CPAP treatment was observed in patients with sleep apnea. ; Introducción: La terapia con CPAP es el tratamiento de primera línea para la apnea del sueño y su eficacia depende de la adherencia.
