Prospective evaluation of Ceftriaxone use in medical and emergency wards of Gondar university referral hospital, Ethiopia

Ceftriaxone is among the most commonly utilized antibiotics owing to its high potency, wide spectrum of activity, and low risk of toxicity. It is used to treat different types of bacterial infections including pneumonia, bone infections, abdominal infections, Skin and soft tissue infections, urinary tract infections. However, evidence around the globe shows the misuse of Ceftriaxone. This study aimed at evaluating the appropriateness of ceftriaxone use in medical and emergency wards of Gondar university referral hospital (GURH), Northwest Ethiopia. A prospective, cross-sectional study design was employed to evaluate the use of ceftriaxone. The medical records of patients who received ceftriaxone were reviewed prospectively between January 1 and March 30, 2017. Appropriateness of ceftriaxone use was evaluated as per the protocol developed from current treatment guidelines. A total of 390 patients' medical records were reviewed. The utilization rate of ceftriaxone was found to be high with a point prevalence of 59%. Ceftriaxone was empirically used in 79.5% of cases. The most common indications of Ceftriaxone were respiratory tract infections (29.3%), central nervous system infections (24.1%), and prophylactic indications (16.4%). The mean duration of ceftriaxone therapy in our study was 11.47 days, with a range of 1-52 days. More than two-thirds (80.2%) of ceftriaxone use were found to be inappropriate and majority of unjustified ceftriaxone use emanated from inappropriate frequency of administration (78.3%), absence of culture and sensitivity test (68.7%), and duration of therapy (47%). Empiric treatment with ceftriaxone and the presence of coadministered drugs was significantly associated with its inappropriate use. The present study revealed a very high rate of inappropriate use of ceftriaxone which may potentially lead to emergence of drug-resistant microorganisms and ultimately exposes the patient to treatment failure and increased cost of therapy.
