Background: Excessive use of ceftriaxone contributes to the emergence and spread of antimicrobial resistance (AMR). In low and middle-income countries, antibiotics are overused but data on consumption are scarcely available. We aimed to determine the prevalence and factors influencing ceftriaxone prescription in a tertiary care private not-for-profit hospital in Uganda. Methods: A cross-sectional study was carried out from October 2019 through May 2020 at Mengo Hospital in Uganda. Patients admitted to the medical ward and who had been prescribed antibiotics were enrolled. Sociodemographic and clinical data were recorded in a structured questionnaire. Bivariate and adjusted logistic regression analyses were performed to determine factors associated with ceftriaxone prescription. Results: Study participants were mostly female (54.7%). The mean age was 56.2 years (SD: 21.42). The majority (187, 73.3%) presented with fever. Out of the 255 participants included in this study, 129 (50.6%) participants were prescribed ceftriaxone. Sixty-five (25.5%) and forty-one (16.0%) participants had a prescription of levofloxacin and metronidazole, respectively. Seven participants (2.7%) had a prescription of meropenem. Out of 129 ceftriaxone prescriptions, 31 (24.0%) were in combination with other antibiotics. Overall, broad-spectrum antibiotic prescriptions accounted for 216 (84.7%) of all prescriptions. Ceftriaxone was commonly prescribed for pneumonia (40/129, 31%) and sepsis (38/129, 29.5%). Dysuria [OR = 0.233, 95% CI (0.07–0.77), p = 0.017] and prophylactic indication [OR = 7.171, 95% CI (1.36–37.83), p = 0.020] were significantly associated with ceftriaxone prescription. Conclusions: Overall, we observed a high prevalence of prescriptions of ceftriaxone at the medical ward of Mengo Hospital. We recommend an antibiotic stewardship program (ASP) to monitor antibiotic prescription and sensitivity patterns in a bid to curb AMR.

Introduction: Effective antimicrobial stewardship programs require data on antimicrobial consumption (AMC) and utilization (AMU) to guide interventions. However, such data is often scarce in low-resource settings. We describe the consumption and utilization of antibiotics at a large tertiary-level hospital in Uganda. Methods: In this cross-sectional study at Kiruddu National Referral Hospital, we analyzed medicine delivery records for the period July 2021 to June 2022, accessed on 12/08/2022, to extract AMC data expressed as defined daily doses (DDDs) per 1000 inhabitants per day (DID). We used the WHO point prevalence survey (PPS) to analyze AMU data with a systematic sampling of outpatient department (OPD) for a period between June and August 2022 and selected all inpatient department (IPD) patients admitted before 8:00 AM on 27/11/2022. AMU data was analyzed as the proportion of individual antibiotic prescriptions, indications for prescriptions, and compliance with the national treatment guidelines. Both AMC and AMU data were categorized by the WHO AWaRe (access, watch, and reserve) criteria. Results: In the year 2021–2022, a total of 6.05 DID of antibiotics were consumed comprising 3.61 DID (59.6%) access, 2.44 DID (40.3%) watch, and 0.003 (0.1%) reserve antibiotics. The most consumed antibiotics comprised penicillin (1.61 DID, 26.7%), cephalosporins (1.51, 25%), and imidazole (1.10 DID, 18.1%). A total of 119/211 (56%) patients in the OPD and 99/172 (57.5%) patients in the IPD were prescribed antibiotics. Of the 158 OPD antibiotic prescriptions, 73 (46.2%) were access, 72 (45.6%) were watch, 0 (0%) were reserve, and 13 (8.2%) were unclassified antibiotics. Of the 162 IPD antibiotic prescriptions, 62 (38.3%) were access, 88 (54.3%) were watch, 01 (0.6%) was reserve, and 11 (6.8%) were unclassified antibiotics. Indications for antibiotic prescriptions in the OPD comprised respiratory tract infections (53, 38.1%), urinary tract infections (34, 26.6%), gastrointestinal infections (20, 14.4%), sepsis (17, 12.2%), and medical prophylaxis (12, 8.7%). The indications for antibiotic prescriptions in the IPD comprised sepsis (28.2%), respiratory tract infections (18.3%), burn wounds (14.1%), and gastrointestinal infections (14.1%). Conclusion: Prescription of watch antibiotics in both OPD and IPD hospital settings was high. Establishment of robust antimicrobial stewardship measures could help improve the rational prescription of antibiotics.

Background: Antimicrobial misuse and overuse propagate antimicrobial resistance, yet data on factors influencing antibiotic prescription decisions in low-resource settings are limited. We describe factors influencing antimicrobial prescription at a large tertiary care private not-for-profit hospital in Uganda. Methods: We conducted a descriptive phenomenology qualitative study involving face-to-face in-depth interviews of 12 purposively selected prescribers (four intern doctors, six medical officers and two Internal Medicine physicians) in a private not-for-profit hospital in Kampala, Uganda. Audio recordings and filed notes were transcribed verbatim and analysed manually by content analysis. Emerging themes and sub-themes were recorded and reported. Results: Three broad themes emerged: experience with antimicrobial use in Uganda, barriers and facilitators to rational antimicrobial prescription and measures to address irrational antimicrobial use. Participants recognized that antibiotics are often used irrationally, prescribed even when there is uncertainty regarding clinical evidence for infection, and influenced by drug promoters, and noted high levels of antibiotic resistance. Patients’ symptoms and clinical signs, previous experience using antibiotics, fear of bad outcomes, patient demand and expectations, influence from senior colleagues, the turnaround time of clinical investigations and drug marketers were the barriers and facilitators to antimicrobial prescription. Prescribers also acknowledged the need to update clinical guidelines, set up hospital antibiograms, and provide continuous medical education on rational antimicrobial use. Conclusions: A complex interplay of intrinsic and extrinsic factors influences antibiotic prescribing decisions in this hospital. Targeted interventions through continuous education and training for prescribers, providing local prescription guidelines and antibiograms and implementing regulations on over-the-counter antibiotic sales are needed to implement robust antimicrobial stewardship programmes to curb antimicrobial resistance successfully.

Context: Neuroleptic malignant syndrome (NMS) is an uncommon but serious adverse event to antipsychotic medications. Case Details: A 14-year-old Ugandan lady presented with high grade fevers, multiple convulsions, altered mentation and lead-pipe rigidity following an intramuscular injection of zuclopenthixol acetate (as Clopixol-Acuphase®). Her labs were significant for elevated aminotransferases and leucocytosis. She had a normal brain CT scan, renal function and cerebrospinal fluid analysis. Discontinuation of Clopixol, administration of bromocriptine 5mg once daily and dantrolene 25mg three times a day and supportive treatment resulted in a complete neurological recovery within 4 weeks of the onset of symptoms. Discussion: Early diagnosis and prompt supportive therapy are required to reduce mortality and morbidity. Early recognition of symptoms and discontinuation of offending agent by health care providers are needed to have recovery even in settings with limited resources.
