Cost of nosocomial infection in Turkey: an estimate based on the university hospital data

Abstract

Nosocomial infections significantly affect the resource needs of hospitalized patients. They increase the mortality and morbidity of affected individuals and expose hospital staff to increased risk of infection. To estimate the additional resources needed in the hospital sector to deal with such infections, a sample of infection cases was selected from the Hacettepe University Hospital in Ankara, Turkey. Each case of nosocomial infection was matched with a noninfected case after controlling for age, sex, clinical diagnosis etc. of the patients. The empirical results indicate that hospital infection increases the average hospital stay by about four days. Total cost of an infected case, on average, was found to be $442 higher than that for a matched noninfected case. Using this incremental cost estimate, projections for Turkey implies that the hospital sector had to spend an additional $48 million in 1995 for medical management of nosocomial infections. The benefit:cost ratio for a hospital-based infection control programme is found to be about 4.6. Clearly, a programme for preventing nosocomial infections will not only pay for itself but also will generate other direct and indirect benefits to patients and society as a whole.
