The study examines the direct effects of Covid-19 on the delivery of inpatient care in Croatia. Materials and Methods: The research is a comparative analysis of the hospital admission rate across all DRG classes before and during the Covid-19 pandemic. It used DRG data from all non-specialized acute hospitals in Croatia, which account for 96% of the national in patient activity. It also uses data from the Croatian Public Health Institute’s (PHI) Covid-19 database. Results: It was found that in 2020, there was a 21% decrease in the total number of admissions across the hospital network, with the greatest drop occurring in April 2020, when admissions plunged by 50%. The decrease in activity occurred in cancers (14%), as well as in non-elective DRG classes such as: Stroke; Major Chest Procedures; Heart Failure & Shock; and Renal Failure. Coinciding with this reduction however, there was a 37% increase in case activity across six Covid-19 related DRG classes. Conclusions: The reduction in hospital inpatient activity during the Covid-19 period in Croatia, was due to a mix of factors such as lock-down and associated quarantining, reorganizations of hospital operations, and medical workforce rationing. Further research is needed to examine the aftermath of the disruption to hospital care in Croatia. Also, a review of response procedures to emergencies such as Covid-19 should be undertaken with the aim of minimizing their adverse effect on other, and equally important community health care needs.
