Impact of COVID-19 on Heart Failure Hospitalizations.

ABSTRACT

The Novel Coronavirus Disease 2019 (COVID-19) pandemic has transformed individual lives and societal framework on a global scale, and in no other sector is this more evident than healthcare. Herein, we aim to describe the impact of the current COVID-19 pandemic and its associated restrictions on heart failure (HF) admissions. In this retrospective cohort study, we obtained administrative data for patients with a primary discharge diagnosis of HF (identified by ICD-10 code) with discharge dates ranging from January 2019 to November 2020. The study is comprised of 2 distinct sub-cohorts HF admissions during the COVID-19 pandemic (case) period from March 2020 to October 2020 and corresponding control period during the previous year (March 2019 to December 2019). Primary outcome analysis involved comparison of total and daily HF admissions and secondary outcomes included hospital Length of Stay (LOS) and 30-day readmissions. The number of total HF admissions and average daily admissions were significantly lower in 2020 compared to 2019 (774 vs. 864; p < 0.001 and 3.17 vs. 3.53 days; p < 0.001), respectively. Average length of stay was significantly higher between March and October 2020 relative to the same months in 2019 (6.05 vs. 5.25 days; p < 0.001). Thirty-day readmission rates were also significantly higher in March-October 2020 compared to the same months in 2019 (20.6% vs. 19.1%; p < 0.001). During the pandemic, both readmission rates and length of stay for HF-related admissions were significantly impacted. The COVID-19 pandemic significantly impacted HF-related admissions as well as associated LOS and 30-day readmissions. High-risk patients should be identified carefully, and timely and appropriate treatment should be provided.
