Abstract
Introduction: A strategy for healthcare surge control in the Covid-19 pandemic is forward triage by on-demand telemedicine (TM), implemented by several providers. We aimed to evaluate the impact of a large-scale Covid-19 TM system on visits to emergency medical services (EMS) and all-cause and cardiovascular (CV) hospital admissions during the pandemic in Brazil. Methods: From March 18 - May 18, 2020 we evaluated the database of UNIMED-BH, a cooperative Brazilian private health insurance, with over 1.25 million clients. The Covid-19 TM system consisted of: a) online mobile app with questions about Covid-19 symptoms, which redirects to teleconsultations in case of moderate/severe manifestations; b) telemonitoring system, with regular phone calls to all clients with reported flu-like symptoms or Covid-19 diagnosis, to monitor disease progression; c) 24/7 emergency call and ambulance system (GMOV), with VOIP triage and counselling by 2 physicians: calls with suspected Covid-19 or respiratory abnormalities were computed. EMS visits and admissions in all accredited hospitals were recorded, with diagnoses assessed by the Diagnosis Related Groups (DRG) method. Covid-19 lab diagnosis and deaths were identified from the patients’ registries, and outcomes assessed until June 1 st . Results: In 60 days, 24,351 patients (1.9% of clients) accessed one of the TM systems, 59% women, median age was 35±18 years. The most frequently utilized system was telemonitoring (16,717, 69%), followed by teleconsultation (13,350, 55%) and GMOV (683, 3%); 6,330 patients accessed multiple systems. The rates of EMS and hospital admissions for each system were: telemonitoring 19.7% (3,296) and 4.6% (774); teleconsultation 17.3% (2,312) and 2.3% (311) and GMOV: 55.9% (382) and 56.2% (384) patients. At total 4.1% (996) had at least 1 hospital admission, 32% (321) with respiratory diseases (41 requiring mechanical ventilation) and 5.6% (56) with CV diagnoses (12 acute coronary syndromes). Overall, 277 (1.1%) patients had confirmed Covid-19 diagnosis, and 160 (0.7%) died, 9 with Covid-19. Conclusion: The TM system resulted in low rates of EMS visits and hospital admissions, suggesting a positive impact on healthcare utilization. The percent of admissions due to CV causes was low.
