    Background/aim: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics. Materials and methods: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician. Results: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had ≤5 years of occupational experience (junior specialists = JSs) and 942 (49.4%) of them were physicians. Specialists having >5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05). Conclusion: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did.

    Increased antimicrobial consumption following reimbursement reform in Turkey
    (Oxford Univ Press, 2008) Karabay, Oğuz; Hoşoğlu, Salih
    Objectives: This study examined antibiotic utilization patterns in Turkey between 2001 and 2006. Methods: A comprehensive collection and analysis of Turkish antibiotic data from 2001 to 2006 was conducted. The anatomical therapeutic chemical (ATC) classification and the defined daily dose (DDD) methodology were used to calculate antibiotic consumption. Data were presented as DDD/1000 inhabitant-days, and the relation between antimicrobial consumption and governmental reimbursement policy was evaluated. Results: Total utilization of antibiotics increased from 14.62 to 31.36 DDD/1000 inhabitant-days between 2001 and 2006. The largest increase took place after the implementation of social insurance reform (SIR) in 2005, as evidenced by the DDD ratio increasing 1.87-fold after SIR went into effect. The largest increase occurred in the prescription of penicillins, from 7.13 in 2001 to 14.09 in 2006. Conclusions: In Turkey, antibiotic consumption increased markedly in recent years, in a close relationship, to a new reimbursement policy following the implementation of the SIR, which facilitated the prescription and consumption of drugs compared with the earlier SIR conditions.

    Risk factors for multi-drug-resistant pseudomonas aeruginosa ınfections in a university hospital-a case control study
    (2016) Üstün, Cemal; Hoşoğlu, Salih; Geyik, Mehmet Faruk
    rpose: This study aims to determine the risk factors associated with multi-drug-resistant Pseudomonas aeruginosa (MDR-Pa) infections. Methods: A case control study was conducted at the Dicle University Hospital which is 1150-bed tertiary care teaching hospital in Diyarbakir, Turkey. The study cases were recruited from patients with nosocomial MDR-Pa infections. Two control cases were arranged to compare risk factors of MDR-Pa infections. One of the control groups was composed of patients with non-MDR-Pa infections and the other group with non-MDR Gram-negative bacterial infections except P. aeruginosa. Results: Overall, 225 patients were included in the study, 75 with MDR-Pa infections, 150 control cases (75 non-MDR-Pa and 75 MDR Gram-negative non P. aeruginosa infections). The incidence of MDR-Pa infections was found as 3.1/1,000 admissions. Multivariate analysis showed that multiple invasive procedures (Relative Risk 24.57 (95% Confidence Interval 4.45135.73) p<0.001), burn (RR 13.66 (CI 407-45.80) p<0.001), malignity (RR 12.50 (CI 2.64-59.20) p=0.001), pneumonia (RR 11.91 (CI 2.44-58.16) p=0.002), carbapenem use (RR 4.92 (CI 1.60-15.09) p=0.005) and long hospitalization (> 10 days) (RR 4.68 (CI=2.09-10.49) p<0.001), were found to be risk factors for MDR-Pa. Conclusions: This study revealed that severity of clinical course and carbapenem use are significant risk factors for MDR-Pa infections
