Health Care Personnel Workdays Lost and Direct Health Care Salary Costs Incurred due to COVID-19 Infection in the Age of Widespread Vaccine Availability.

BACKGROUND

Vaccination against coronavirus disease 2019 (COVID-19) can mitigate the burden of health care worker (HCW) infection. We investigate the burden of HCW illness and its associated direct health care personnel costs in the setting of widespread vaccine availability and explore factors influencing these outcomes.

METHODS

This multicenter prospective study followed HCWs over an 8-month period from January to August 2023. Data recorded included incident COVID-19 infection, symptom burden, workdays missed, and vaccine history. Workdays lost due to illness were used to calculate direct health care personnel costs due to COVID-19 infection. Univariate analysis and multivariable regression investigated the factors associated with workdays lost and direct health care personnel.

RESULTS

In total, 1218 participants were enrolled and followed for 8 months, with 266 incidents of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, 1191 workdays lost, and health care personnel costs of €397 974. Multivariable regression revealed that workdays lost were associated with incomplete primary COVID-19 vaccination course. Being unvaccinated, older age, and male were associated with increased health care personnel costs.

CONCLUSIONS

Health care workdays lost remain a significant issue and are associated with health care system burden despite vaccine availability. These can be mitigated via targeted implementation of vaccine programs. Seasonal variation in health care workdays lost should inform workforce planning to accommodate surge periods.
