Changes in hospital admissions for urgent conditions during COVID-19 pandemic

To determine whether patients are deferring necessary care for urgent conditions during the coronavirus disease 2019 (COVID-19) pandemic and, if so, to what extent.

Cross-sectional study.

Using billing data from 8 acute care hospitals, we identified 9 principal medical diagnoses from International Classification of Diseases, Tenth Revision codes across 4 medical specialties (cardiology, gastroenterology, neurology, and urology). In addition, we defined a combined obstetrical falsification end point. We compared daily admission rates during the pandemic period (3/1/2020-4/30/2020) with the same dates in 2019 (3/1/2019-4/30/2019). As a reference, we also compared a prepandemic period in the same years (1/1/2019-2/28/2019 and 1/1/2020-2/29/2020). We compared admission rates between years using t tests.

There were 3219 admissions for the conditions of interest during the study period in 2019 and 2661 in 2020. There was no difference in prepandemic daily admission rates in 2020 compared with 2019 (29.04 vs 27.63 admissions per day; -4.9%; P = .50). During the pandemic period, there was a 33.7% decrease in admission rates for all conditions combined in 2020 compared with 2019 (24.68 vs 16.37; -33.7%; P = .03). By specialty, the combined gastroenterology (10.22 vs 7.20; -29.6%; P = .02) and cardiovascular (2.34 vs 1.29; -44.7%; P = .05) end points demonstrated reduction in daily admission rates.

Daily admission rates during the COVID-19 pandemic were lower for these acute medical conditions. Public awareness campaigns are urgently needed to reassure the public about the safety of presenting for care.
