Abstract
BACKGROUND: Preoperative antibiotic prophylaxis is one of the preventive measures for surgical site infections (SSIs). Very little data about the cost effectiveness of the appropriate duration of antibiotic prophylaxis in low- and middle-income countries are available. We aim to assess the cost effectiveness of the use of antibiotic prophylaxis for <24 hours to prevent neurosurgical infections in a middle-income country, Turkey. METHODS: A 1-year prospective study was performed between June 2012 and June 2013. During this study period patients were followed-up on for the development of SSI by means of hospital and postdischarge surveillance. Patients included in the study group received appropriate duration of antibiotic prophylaxis (<24 hours), and the duration of prophylaxis was longer in the control group. The antibiotic costs per patient, including prophylaxis and treatment, were calculated. RESULTS: A total of 822 operations consisting of craniotomy (n = 558), spinal fusion (n = 220), and ventricular shunt (n = 44) were included in the study. The study group included 488 (59.4%) patients who underwent operations with appropriate duration (<24 hours) of antibiotic prophylaxis. Prophylactic antibiotic cost per patient was significantly lower in the study group ($3.35 and $20.41, respectively). The SSI rates did not differ between the 2 groups: 3.5% (17/488) in the study group and 3.6 (12/822) in the control group (P > .05). CONCLUSION: This cost-analysis study demonstrates that prolonged antibiotic prophylaxis correlates with increased burden of cost, but it is not preventive for SSI.
