In a latest research posted to the medRxiv* preprint server, researchers in Australia characterised hospitalization volumes, affected person epidemiological and scientific final result information of sufferers admitted to digital wards throughout the predominance of the extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant of concern (VOC) BA.1 sub-VOC and the Omicron BA.2 sub-VOC.
The Metro North COVID-19 Virtual Ward was designed to offer care at dwelling for folks with COVID-19 in South-East Queensland, Central West, and Norfolk Island. This space covers an estimated 900,000 folks and 4157 sq. kilometers. There are 22 public hospitals inside these catchments, together with one quaternary, one tertiary, and two secondary hospitals.

About the research
In the current retrospective research, researchers evaluated hospitalization necessities amongst digital ward sufferers throughout Omicron BA.1 and Omicron BA.2 predominance.
The research comprised care people admitted to digital wards aged above 16 years and hospitalized between January 1, 2022, and March 25, 2022. Clinical, laboratory, and epidemiological information of sufferers requiring hospitalization had been analyzed. The crew excluded short-term admissions in emergency departments (ED) and people hospitalized to obtain intravenously delivered anti-SARS-CoV-2 therapeutics.
Data had been obtained from a number of on-line scientific word methods such because the Power BI (Ward dashboard), Virtual Care Stream, The Viewer, and iEMR. Virtual ward admissions of the people had been based mostly on opt-in modeling, and SARS-CoV-2-positive RAT (fast antigen check) or PCR (polymerase chain response) stories.
In addition, different practitioners (comparable to ED or basic practitioners) referred sufferers or the care people had been admitted based mostly on self-referrals from telephonic calls or digital platforms. The ward comprised nursing, administration, pharmacy, social, and medical work workers. During preliminary consultations, sufferers had been categorized based mostly on their dangers of potential COVID-19 development into very-high, excessive, reasonable, and low/very-low-risk teams.
Participants had been contacted every day by way of phone, and their signs had been evaluated based mostly on standardized standards for affected person escalation. In addition, a pulse oximeter was distributed to high-risk COVID-19 sufferers. The ward allowed affected person escalation to MO (Medical Officers) for reviewing and ED transfers if wanted, with informing the Senior MO (SMO) of the corresponding ED of the affected person’s arrival.
Analgesics, antibiotics, antivirals, and antiemetics had been prescribed based mostly on the nationwide tips of Australia and had been obtainable for dwelling supply when required. The people obtained ward discharge every week after assembly the nationwide tips regarding symptom enchancment. Immunocompromised people, comparable to these with liver or lung transplants, had been adopted up for 2 weeks within the digital ward in case of ongoing COVID-19 signs.
Data had been obtained on the entire rely of digital ward sufferers, consultations, ED-attended sufferers, and hospitalized sufferers. Details of hospitalized sufferers, together with demographics, comorbidities, the standing of vaccination, SARS-CoV-2 testing stories, causes for affected person escalation, hospital assessments and coverings, pathology stories, digital ward tendencies, and therapy outcomes, had been obtained. In addition, information on in-hospital mortality or deaths inside 30 days post-discharge and re-hospitalizations had been additionally obtained.
Results
In whole, 7,021 COVID-19 sufferers had been taken care of within the digital ward, and 473 had been referred to hospitals for evaluation. Of the ward sufferers, 26 sufferers had been hospitalized throughout their care interval, of which 85% (n=22) had been related to SARS-CoV-2 infections. Of the hospital-admitted sufferers, 53%, 31%, and 15% had obtained full vaccinations, partial vaccinations, and no vaccinations, respectively, and 11 sufferers had been handled by COVID-19 therapeutics.
The median age of the hospitalized sufferers was 62 years, and most (65%) of them had been females. 50%, 42%, eight p.c, and 0 p.c of hospitalized sufferers belonged to the very excessive, excessive, reasonable, and low/very low-risk classes, respectively. One affected person was admitted to the intensive care unit (ICU), and one affected person died within the hospital.
Breathlessness (50%) and ache within the chest of non-cardiac origin (39%) had been probably the most generally noticed causes for hospitalization. Among ward-treated sufferers, 27%, eight p.c, 4 p.c, 4 p.c and 58% had been handled with budesonide, elevated inhalational corticosteroids, sotrovimab, molnupiravir, and not one of the medicine, respectively. Within 30 days of discharge, one affected person was re-hospitalized.
The median size of keep amongst hospitalized sufferers was three days. 23% of instances had been gentle, 39% reasonable, 27% extreme, and eight% crucial COVID-19. Among the sufferers hospitalized, 19% got budesonide or different inhaled corticosteroids, 42% used dexamethasone, 38% used oral steroids, 4% used remdesivir, 8% baricitinib, whereas 38% obtained oxygen remedy.
Overall, the research findings confirmed that only some COVID-19 sufferers cared for within the digital ward required hospitalizations throughout Omicron BA.1 and Omicron BA.2 sub-VOC predominance as a direct impact of SARS-CoV-2 infections. The findings might support hospital-need planning and optimizing care in digital ward settings.
