Background:
The screening of critically ill patients at high risk of vancomycin resistant enterococci (VRE) colonization, to detect and isolate colonized patients, is recommended to prevent and control the transmission of VRE. Screening asymptomatic carriers brings financial burden for institutions. In this study, we performed risk analysis for VRE colonization and determined the financial burden of screening in a middle-income country, Turkey.
Methods:
We retrospectively analyzed the VRE surveillance data from a pediatric hospital between 2010 and 2014. A case-control study was conducted to identify the risk factors of colonization. Total cost of VRE screening and additional costs for a VRE colonized patient (including active surveillance cultures and contact isolation) were calculated.
Results:
During the 4-year period, 6,372 patients were screened for perirectal VRE colonization. The rate of culture-positive specimens among all patients screened was 239 (3.75%). The rate of VRE infection was 0.04% (n = 3) among all patients screened. Length of hospital stay, malignancy, and being transferred from another institution were independently associated risk factors for colonization. Annual estimated costs for the laboratory were projected as $19,074 (76,295/4) for all patients screened. Cost of contact isolation for each patient colonized in a ward and an intensive care unit was $270 and $718, respectively.
Conclusions:
In developing countries, institutions should identify their own high-risk patients; screening priorities should be based on prevalence of infection and hospital financial resources.
