Abstract
Background
The goal of this work was to compare the incidence and characteristics of medically-attended acute gastroenteritis (MAAGE) prior to and since the SARS-CoV-2 pandemic within a US-based integrated health care delivery system.
Methods
We identified all-age MAAGE encounters from 7/1/17-6/30/24, using diagnostic codes in the electronic health record and included clinical gastrointestinal (GI) pathogen testing and results performed ±3 days of encounter. We compared MAAGE incidence rate ratios (IRRs) and health care utilization metrics between early (7/1/17-6/30/19) and late (7/1/23-6/30/24) study periods through Poisson regression modeling and chi-square testing, respectively.
Results
MAAGE incidence was similar in the late compared to early study periods (IRR 1.01 [CI 1.00, 1.03]). Compared to the early period, the late period saw a higher proportion of remote (27.1% vs 14.0%) and lower proportion of outpatient (43.0% vs 54.8%) encounters; a lower proportion of encounters with GI testing (7.2% vs 8.7%); and lower norovirus positivity (4.7% vs 5.3%); all p
