Costs of inpatient care and out-of-pocket payments for COVID-19 patients: A systematic review.

The results show that the COVID-19 disease imposed a high cost of hospitalization, mainly the cost of hospital beds/day of routine services. Studies have used different methods for calculating the costs, and this has negatively impacted the comparability costs across studies. Therefore, it would be beneficial for researchers to use a similar cost calculation model to increase the compatibility of different studies. Systematic review registration: PROSPERO CRD42022334337.
