Evaluation of ceftriaxone use in the medical ward of Halibet National Referral and teaching hospital in 2017 in Asmara, Eritrea: a cross sectional retrospective study.

Background: Antibiotic resistance due to overuse of antimicrobials is an issue that has been of concern to many health institutions and society in general. Resistant infections have high impact in low income countries since they can't afford more recent and expensive antibiotics. Studies that evaluate antibiotic use in hospitals are scarce in Eritrea. Ceftriaxone is commonly available in Halibet National Referral and teaching hospital (HNRTH). Resistance to this antibiotic would have a great impact on the hospital since there is no other available third generation cephalosporin or higher classes of antibiotics.

Method: A retrospective cross sectional design was used to evaluate the use of ceftriaxone in patients admitted to the medical ward in 2017. Clinical card number of inpatients who took ceftriaxone was extracted from the database of the Satellite Pharmacy Department of HNRTH and collected using a standardized data collection form. A descriptive analysis was employed and the Statistical package for social sciences (SPSS), version 20 was used for analysis.

Results: A total of 120 patients were taking ceftriaxone for various indications. There were 55 (50.5%) males and 54 (49.5%) females. 59.8% of the patients were treated in the range of 0-7 days. The mean age was 56 (SD: 20.7). On average patients were under treatment for 6 days. The proportion of patients taking ceftriaxone was 11.43% out of all admissions in the medical ward. One, two or three antibiotics were co-prescribed with ceftriaxone in 39.4%. The most commonly co-prescribed antibiotic was gentamycin, accounting for 16.4% of the co-administered antibiotics. The most common indications for ceftriaxone were pneumonia, sepsis, TB, and CHF. Ceftriaxone therapy was appropriate in 30 (27.5%) cases and 68 (62.4%) cases were inappropriate in any of the four parameters of assessment used.

Conclusion: Inappropriate use of ceftriaxone was found to be high in the hospital. This calls for establishment of hospital and national guidelines of antimicrobial treatment. Moreover drug restriction and antibiotic stewardship implementation in the hospital should be sought to prolong the lives of important drugs like ceftriaxone.
