Özet:

The Turkish Ministry of Health has released a regulation in February 2003 in order to decrease, first the antibiotic expenses and second, inappropriate use of antimicrobial agents. The aim of this study is to assess the impact of this nationwide antibiotic restriction (NAR) in the most active stem cell transplantation unit (SCTU) in Turkey. All patients followed up in SCTU and had received antimicrobial therapy in the period of four months before and after NAR were evaluated retrospectively. The appropriateness of antimicrobial treatments was assessed by two ID specialists and one ID professor. Disagreements between investigators were solved by discussion and review of published guidelines. There were 10 and 25 patients who were on antimicrobial therapy in the 1st (before NAR) and 2nd (after NAR) group, respectively. Seventeen of the patients had undergone allogeneic stem cell transplantation, while 6 were allogeneic bone marrow recipients and 12 were autologous peripheral stem cell recipients. The antibiotic days per patient was 33.4 and 19.4 in the first and second groups respectively (p=0.036). Although it was not significant, the appropriateness of antibiotic regimens used in the second group was higher than the first group (OR: 5, CI: 0.9-26.4, p= 0.059). The significantly lower antibiotic day per patient in the 2nd group may be the result of collaboration between infectious diseases and hematology physicians settled after NAR in our hospital. NAR had reduced the antimicrobial use in our unit mainly by providing collaboration between infectious diseases and hematology departments.
