Identifying Adverse Events in Patients Hospitalized in Isolation or Quarantine Due to COVID-19.

Abstract

This study evaluated the adverse events of COVID-19 isolation or quarantine in patients with nosocomial SARS-CoV-2 infection admitted to the Hospital Universitario Insular de Gran Canaria. This is a retrospective cohort study with 30-day follow-up of 126 patients diagnosed with nosocomial COVID-19 through polymerase chain reaction test, between May 1 and June 30, 2022, in a 500-bed university hospital in the island of Gran Canaria. Between May 1 and July 30, 2022, a total of 2250 patients were admitted to the Hospital Universitario Insular de Gran Canaria; 126 of them were diagnosed with nosocomial COVID-19 through a polymerase chain reaction test. The rate of nosocomial COVID-19 infection was 5.6%. From the 126 patients of the study population, 27 experienced an adverse event (21.4%) and 2 experienced 2 adverse events (1.6%) due to COVID-19 isolation or quarantine. Thus, a total of 31 adverse events occurred in 29 patients. These events included the following: delay in transfer to other centers of 11 patients who were pending of receiving a negative COVID-19 test result (35.5%), delay or cancellation of diagnostic tests in 9 patients (29%), delay or cancellation of doctor visit in 7 patients (22.6%), and delay or cancellation of surgical or other interventions in 4 patients (12.9%). Because of the adverse consequences of nosocomial COVID-19 infection in hospitalized patients, measures should be observed for the prevention and control of nosocomial infection transmission, and adverse events related to patient safety issues in health care in isolated or quarantined COVID-19 patients should be prevented.
