![]() 7 In this context, pulse oximetry is a convenient tool for monitoring patients’ SpO 2 remotely and establishing whether they require hospital care or can be safely managed at home, 8 and different RPM models have included pulse oximeters as part of their monitoring packages for patients with COVID-19. 6Įvidence shows that peripheral blood oxygen saturation (SpO 2) is a critical indicator of deterioration in patients with COVID-19. 5 Digitally enabled health-care models that incorporate RPM could offer a more personalised approach to responding to patients’ needs. 4 However, the COVID-19 pandemic and the resulting changes in health-care delivery have encouraged the adoption of remote patient monitoring (RPM) models, and represented an opportunity to use RPM as a crucial part of health-care delivery. The unprecedented increase of COVID-19 cases globally has overwhelmed health systems and challenged their capacities, 2, 3 leading to extensive risks to patient health and wellbeing. 1 Part of this innovation includes the possibility of monitoring patients in their home environment. Technological innovation has reshaped the modern world such that health care has become a continuous process rather than service points. Based on our findings, we make 11 recommendations across the three Donabedian model domains and highlight three specific measurements for setting up an RPM system with pulse oximetry. The use of pulse oximetry can potentially save hospital resources for patients who might benefit the most from care escalation however, we could not identify explicit evidence for the effect of RPM with pulse oximetry on health outcomes compared with other monitoring models such as virtual wards, regular monitoring consultations, and online or paper diaries to monitor changes in symptoms and vital signs. Our systematic review substantiates the safety and potential of pulse oximetry for monitoring patients at home with COVID-19, identifying the risk of deterioration and the need for advanced care. A meta-analysis was not feasible owing to the heterogeneity of the outcomes reported in the included studies. These 13 studies were all observational cohorts and involved a total of 2908 participants. We found 561 studies, of which 13 were included in our narrative synthesis. We searched five databases (MEDLINE, Embase, Global Health, medRxiv, and bioRxiv) from database inception to April 15, 2021, and included feasibility studies, clinical trials, and observational studies, including preprints. In this systematic review, we aim to assess the effectiveness and safety of pulse oximetry in remote patient monitoring (RPM) of patients at home with COVID-19. The COVID-19 pandemic has led health systems to increase the use of tools for monitoring and triaging patients remotely.
