Characteristics and outcomes of COVID-19 home monitoring in Saudi Arabia during the second and third waves

Abstract

Introduction: As severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spread around the world, patient care was shifted to outpatient care and home monitoring. This paper describes the characteristics and outcomes of patients with coronavirus disease 2019 (COVID-19) treated at home during the second and third waves in Saudi Arabia. Materials and methods: Descriptive evaluation of the characteristics and outcome of COVID-19-positive cases enrolled in the home monitoring programme. Results: This study included 14,970 SARS-CoV-2-positive patients (52.6% male). The mean age was 30.8 [standard deviation (SD) 19.9] years. Among the confirmed cases, 14,234 had documented vaccination status; of these, 3943 (27.7%) had not received any doses of COVID-19 vaccine, 1452 (10.2%) had received one dose, 4882 (34.3%) had received two doses, and 3957 (27.8%) had received three doses. The mean number of days in the home monitoring programme was 8.3 (SD 3.5) days. The mean interval from the last vaccine dose until SARS-CoV-2 infection was 116.6 (SD 75.5) days in 7975 patients. The presence of comorbidities was as follows: chronic kidney disease, 340 (2.3%); hypertension, 2569 (17.2%); chronic pulmonary disease, 2539 (17%); smoking, 1711 (11.4%) of 9269 with documented smoking histroy; coronary artery disease, 854 (5.7%); and diabetes mellitus, 1531 (10.3%). The hospitalization rate was 1.8%, and the case fatality rate was 5% of admitted patients, accounting for 0.11% of all cases. The mean age of patients who died was 76.6 (SD 17.7) years, which was higher compared with the mean age of those who survived [30.8 (SD 19.9) years] (P<0.001). Conclusion: Utilization of a home monitoring programme was effective and safe for patients with COVID-19 who were either asymptomatic or had mild symptoms.
