Outcomes
The primary outcome was feasibility of a trial of home monitoring by pulse oximetry defined as successful inclusion of approximately 50 participants within 6 months who were willing to a) be randomised; and b) adhere to study procedures.Secondary outcomes included quantitative data about the use of pulse oximetry in practice (see process evaluation below), patient-reported feeling of safety over the first 2 weeks, and disability-free survival after 45 days as determined by percentage change in 12-item WHODAS 2.0 sum score from baseline to 45 days: number of GP consultations, number of emergency department (ED) visits, hospital and/or intensive care unit (ICU) admissions, number of days alive at home, and all-cause mortality.
