Authors' conclusion

Heart failure with reduced ejection fraction medication rates for Veterans were generally sustained or improved during the study period, but care gaps remain. Telehealth replaced some in-person primary and specialty care early in the pandemic, and in-person primary care has sustained at lower rates than before the pandemic. The rate of hospitalization sustained at lower levels while mortality has increased.
