Impact on the incidence of gastrointestinal perforation during the COVID-19 pandemic in the Costa del Sol healthcare system area.

Introduction and aims: Gastrointestinal perforation is a surgical emergency that is associated with a high mortality rate and requires special care. During the pandemic, there has been competition with COVID-19 patients for health resources, especially ICU bed availability. The primary aim of our study was to compare the incidence of gastrointestinal perforation during the COVID-19 pandemic, with cases registered before the pandemic.

Materials and methods: A retrospective, observational, single center, cohort study was conducted that included patients that underwent emergency surgery for gastrointestinal perforation in the periods during the pandemic (6 months) and before the pandemic (12 months). Sociodemographic characteristics, comorbidities, duration of hospital and ICU stay, status at discharge, and perforation site were compared.

Results: The study included 67 subjects (33 in the pre-pandemic period and 34 in the pandemic period). There were no significant differences regarding sex, age, or comorbidity. The perforation rate per emergency intervention was 4-times higher during the pandemic. There was an increase in the number of patients that were foreigners (4 [11%]) and nonresidents (6 [17%]). ICU admissions decreased (6 [19%]) but ICU stay increased to 137 h. Hospital stay increased by 5 days and delay in care increased 4.5 h. The number of deaths was higher (from 5 [15.2%] to 10 [29.4%]). Four patients with perforations were positive for COVID-19, were admitted to the ICU, and died.

Conclusions: During the COVID-19 pandemic there was an increase in the incidence of gastrointestinal perforations at our healthcare system area; symptoms were more advanced, and mortality was higher.
