Telehealth in Australian cardiology: insight into factors predicting the use of telephone versus video during the COVID-19 pandemic.

backgroundThe use of telehealth has increased dramatically in Australia in 2020 as a pragmatic response to the COVID-19 pandemic; however, differences between telehealth modalities have not been established.

aimTo identify characteristics contributing to choosing telephone (TP) versus video consultation (VC) and assess patient outcomes between telehealth modalities.

methodsWe conducted an observational study of cardiology outpatients at a tertiary hospital with appointments from 17 March 2020 to 12 August 2020. Demographic variables and appointment modality were compared between each group. Outcomes assessed were mortality, emergency department (ED) presentations and cross over between appointment modalities.

resultsThere were 1754 telemedicine encounters with 1188 patients seen by TP and 327 patients by VC. Consulting volume increased from previous years. Cardiac mortality was low (0.3%). There were no differences in mortality or ED presentations between telehealth modalities. Patients choosing TP over VC were older (P < 0.001), more likely to be female (P = 0.005), non-English-speaking (P = 0.041), living in metropolitan Melbourne (P < 0.0001), undertaking a first appointment (P = 0.002) and seeing particular cardiologists (P < 0.001). VC patients were more likely to have early review (P = 0.015), and this was likely to be TP (P < 0.0001). TP patients were more likely to follow up in person (P < 0.0001).

conclusionDuring COVID-19, we increased consultation volumes without adverse patient outcomes. We identified factors influencing the choice of telemedicine modality which did not translate into differences in mortality or ED presentations. Telemedicine is a growing platform with an important role of facilitating access to healthcare for diverse patient groups.
