| Background: Due to the critical role of antibiotics and increasing trend of resistance in developing
countries, comprehensive methods of antibiotic use is necessary to limit the threat of resistant
microorganisms. In this study we compare antibiotics consumption by Defned Daily Dose (DDD) per
100 bed-days in Shahid Ghazi hospitals during three months in Tabriz, Iran.
Methods: This is a retrospective study, which enrolled patients with malignancy who admitted
to Shahid Ghazi hospital from January till March 2016. From all, 58 patients diagnosed with
malignancy and received antibiotics for prophylaxis and/or treatment. For the purpose of Drug
Utilization Evaluation (DUE) all antibiotics, antifungals and antiviruses consumption for any reason
(prophylaxis, empiric therapy, targeted therapy) were recorded. Data on administered medications
such as indication, duration, and dose were compared according to the guidelines of the NCCN
2.2016. The accuracy of antibiotics consumption was assessing by NCCN (2.2016) guideline.
Anatomical Therapeutic Chemical (ATC) code J01 was explained as defned daily doses per 100 beddays (DDD/100) according to the ATC/DDD classifcation. The amount of consumption was assessed
with DDD per 100 bed-days in three months.
Results: from 56 patients, 46 of them had hematologic malignancy and 10 of them had solid tumors.
The indication of antibiotics and antifungal prophylaxis were wrong in 19.6% of indications. The
prophylaxis dosage of antibiotics, antifungal, antiviral and PCP were wrong in 8.8%, 41.7%, 80%
and 50%, respectively. The prophylaxis duration of antibiotics, antifungal, antiviral and PCP were
wrong in 69.4%, 61.2%, 80% and 100% respectively. The dose adjustment of antibiotics with GFR
and renal status of patients, in 8 of 9 patients (88.88%) who received meropenem, and in 9 of 23
patients (39.13%) who received imipenem, were not applicable according standard guidelines. The
total consumption of systemic antibiotics in Ghazi Hospital during 3 months was 5091 (Table 7(.
From all patients 75% of them received antibiotics according to the ATC/DDD classifcation System.
Conclusion: Specifc strategies should be employed in infection control development and engage
rational antibiotic utilization in order to reduce future resistant strains and increase anti-microbial
effcacy. |
