Virtual COVID Ward: The Use Of Telehealth In The Emergency Response To COVID-19

ABSTRACT

IntroductionWith unprecedented times, comes accelerated change. Hospitals in our region have begun to facilitate safe discharge for COVID-19 patients in the form of “The virtual COVID ward”. This has enabled patients to be monitored safely in the community using pulse oximetry, Florence (a telehealth mobile app) and remote consultations. Our objective is to expand upon this model by providing home oxygen therapy for these patients facilitated by telemedicine.MethodsPatients were discharged with an oxygen concentrator if they had an oxygen requirement equal to or less than four litres/minute. Fraction of inspired oxygen needed to be stable and an early warning score of less than four was also required. Once admitted, the Florence app and daily remote consultations were crucial to closely monitor the patient's clinical status. The patient was instructed to enter oxygen saturations and heart rate into the app four times daily. The app would then alert our team if any patients observations deteriorate, triggering immediate assessment.ResultsWe have discharged ninety patients to the virtual ward, fifty-six of these with home oxygen. The average age was fifty-seven and the Clinical Frailty Score ranged between one and six. At present, ten patients have been re-admitted, four with increasing oxygen requirements, and six with unrelated symptoms. Two patients had oxygen concentrators installed at home after we were alerted to their desaturation by the Florence App. The re-admission rate is eleven percent, which mirrors that of other virtual wards (who do not provide home oxygen). In total, the ward has saved the trust 627 hospital inpatient ‘days’. Patients report increased satisfaction at playing a meaningful role in monitoring their own healthcare using the app.ConclusionsOur novel model of supported discharge with oxygen therapy using telehealth demonstrates that it is possible to manage such patients, safely, in the community. Other trusts could utilise this model to reduce inpatient bed occupancy. Looking to the future, could telehealth be utilised further to facilitate other “Virtual wards” in the community?
