Rapid implementation of home oxygen treatment and remote monitoring for COVID-19 patients at the verge of the Omicron wave in Turku, Finland

Abstract

Abstract Background In Turku, Finland, we introduced a home oxygen treatment and app-based monitoring program for hospitalized COVID-19 patients to facilitate an early discharge during the Omicron wave. In this case series we explore the clinical parameters of patients enrolled in the program and evaluate the cost–benefit and safety issues of the program. Methods Hospitalized COVID-19 patients with marked hypoxemia but otherwise in stable condition were screened from Turku City Hospital and Turku University Hospital by treating doctors for eligibility in the program. Peripheral oxygen saturation of > 92% and breathing frequency < 30/min in rest with oxygen supplementation were among the criteria. All patients actively participating in the program between 10th of January 2022 and 30th of September 2022 were included in this case series. Clinical data of hospitalization and monitoring were analysed, and cost–benefit evaluation was based on the number of saved hospitalization days. Results Nineteen COVID-19 patients were included in this case series and recruited from three different hospital departments in the Turku city region, South-West Finland. All patients were male, the median age was 59 years and the median duration of hospitalization before enrolment in the program was 6 days (range 3—20 days). The median duration of home oxygen treatment was 13 days (range 3—72 days) and the median duration of home monitoring was 18 days (range 7—41 days). A total of 210,5 hospital days were prevented, resulting in savings of €144,490 of healthcare expenditure (on average 9 days and €7,605 per patient). No major safety issues were reported during the program. Conclusions In our case series, home oxygen treatment combined with home monitoring was safe and economically beneficial. Application based monitoring could be considered in other post-acute pulmonary conditions to reduce hospitalization and healthcare costs.
