Effect of a Digital Precision Public Health Intervention for Care Coordination During Covid-19 Pandemic in Australia: A Real World Study
Abstract Background: Emergencies disproportionally affect vulnerable populations. The COVID-19 pandemic affected older patients with co-morbidities both directly due to more severe infection and indirectly by affecting care provision. To promote continuity of care, public health professionals require tools to quickly and precisely coordinate with primary care providers. This study evaluated whether digital interventions powered by current existing infrastructure are more effective than conventional interventions in promoting primary care appointments during the COVID-19 pandemic. Methods: We developed a digital intervention delivered by secure messaging and compared it to a post delivered intervention to promote continuity of care for vulnerable veterans during COVID-19 in a real world, non-randomised, interventional study. The study was implemented as part of the Veterans’ MATES program, an Australian Government Department of Veterans’ Affairs program to promote improvements in health care for veterans. The intervention provided patient specific information to general practitioners (GPs) to support continuity of care, alongside mailed education to veterans. The intervention key messages were to maintain regular contact with care providers and to continue to adhere to health plans. The intervention took place in April 2020, during the first weeks of COVID-19 social distancing rules in Australia. The main outcome was time to first appointment with the primary general practitioner (GP) measured using a Cox proportional hazards model.Results: GPs received digital messaging for 51,052 veterans and post messaging for 26,859 veterans. The proportion of patients seeing their primary GP during the three months following intervention was higher in the digital group (77.8%) than the post group (61.5%) (p<0.01). Being in the digital group was associated with earlier appointments. Conclusion: Current infrastructure coupled with innovative solutions is effective in promoting care coordination at scale during national emergencies, opening up new perspectives for precision public health initiatives.
