Sensitivity analysis of hazard rates of 90-day heart failure emergency department visits, hospitalization, and mortality after outpatient visit for heart failure.. Multivariable adjustment adjusted for age, sex, race, insurance status, calendar date, visit length, and visit diagnoses (coronary artery disease, hypertension, atrial fibrillation/flutter, diabetes mellitus, valvular disease, and chronic kidney disease).

Propensity weighting was calculated based on propensity for being seen by remote visit according to above patient characteristics.

Non-Covid-19-surge months excluded outpatient visits during peak months of the Covid-19 pandemic in Los Angeles (June, December)

Abbreviations: HF = heart failure, ED = emergency department, HR = hazard ratio, CI = confidence interval
