Analysis of impact of nosocomial infections on cost of patient hospitalisation.

Objectives: The scale of the economic problem of the occurrence of nosocomial infections and the resulting high additional costs of treatment can only be assessed using economic analyses. The aim of the study was to analyse the impact of a nosocomial infection in a patient in the treatment process and the direct costs of patient hospitalisation. The article contributes to a cost analysis, which is a relevant basis for adopting effective solutions and decisions on the introduction of new programmes and measures to reduce nosocomial infections and associated costs.

Methods: In the first phase of the micro-economic analysis, we analysed the course of hospitalisation of a non-colonised patient treated in an ordinary hospital room. In the second phase, we analysed the process of hospitalisation of a patient who developed a nosocomial infection and was transferred to an isolation room. The difference in cost of both types of treatment allowed us to carry out an economic analysis to estimate the direct costs of nosocomial infection, which are not related to the initial diagnosis of the patient but only to the patient hospitalisation. To calculate the individual types of direct costs of both alternative treatments, we first used the process flow diagram method, which then enabled us to analyse the impact of the occurrence of nosocomial infection on the efficiency and costs of the hospital.

Results: The results showed that the total direct cost of hospitalisation of a non-colonised patient was 1,317.58 euro per day, and the direct cost of hospitalisation of a patient with a nosocomial infection was 2,268.14 euro per day of hospitalisation.

Conclusions: We found that reducing nosocomial infections would have a significant impact on the savings or reduction in healthcare costs associated with a different work process for patients in isolation. It would save 950.56 euro per patient for each day of hospitalisation for individual treatment of a patient hospitalised in an isolation room as consequence of a nosocomial infection.
