Actionable data on antimicrobial use is important when planning strategic interventions such as antimicrobial stewardship to address the challenge of drug resistance, particularly in resource-constrained settings. To assess the prevalence of antibiotic use, the pattern of commonly used antibiotics and patient factors that may be associated with the increased use of antibiotics in the study hospitals. This was a cross-sectional study conducted using the WHO Methodology for Point Prevalence Surveys in hospitals. Chi-squared analysis, Fisher’s exact test and logistic regression were employed to analyse statistically the data obtained. The overall prevalence of antibiotic use in the hospitals was 60.5%. The commonest indications for antibiotic recommendations were community-acquired infections (36.5%), surgical prophylaxis (26.1%) and hospital-acquired infections (15.7%), among others. Very few (2.7%) of the patients had their samples taken for culture and susceptibility testing to guide therapy. Penicillins (48.7%), cephalosporins (23.5%) and fluoroquinolones (17.4%) were the most commonly prescribed antibiotics. Concurrent malaria infection [adjusted OR (AOR) 0.33, 95% CI 0.11–0.94, P = 0.04] and increasing age (AOR 0.98, 95% CI 0.96–1.00, P = 0.02) were associated with lower risk of antibiotic use. The prevalence of antibiotic consumption in the hospitals was lower than that reported in similar studies in Ghana, but high relative to some reports from high-income countries. Most antibiotic therapy was empirical and not guided by culture and susceptibility testing. There is the need for application of the WHO AWaRe classification for the selection of antibiotics and increased use of culture and susceptibility data to guide infectious disease therapy.

Background: Monitoring of antibiotic prescription practices in hospitals is essential to assess and facilitate appropriate use. This is relevant to halt the progression of antimicrobial resistance. Methods: Assessment of antibiotic prescribing patterns and completeness of antibiotic prescriptions among out-patients in 2021 was conducted at the University Hospital of Kwame Nkrumah University of Science and Technology in the Ashanti region of Ghana. We reviewed electronic medical records (EMR) of 49,660 patients who had 110,280 encounters in the year. Results: The patient encounters yielded 350,149 prescriptions. Every month, 33–36% of patient encounters resulted in antibiotic prescription, higher than the World Health Organization’s (WHO) recommended optimum of 27%. Almost half of the antibiotics prescribed belonged to WHO’s Watch group. Amoxicillin–clavulanic acid (50%), azithromycin (29%), ciprofloxacin (28%), metronidazole (21%), and cefuroxime (20%) were the most prescribed antibiotics. Antibiotic prescribing parameters (indication, name of drug, duration, dose, route, and frequency) were documented in almost all prescriptions. Conclusions: Extending antimicrobial stewardship to the out-patient settings by developing standard treatment guidelines, an out-patient specific drug formulary, and antibiograms can promote rational antibiotic use at the hospital. The EMR system of the hospital is a valuable tool for monitoring prescriptions that can be leveraged for future audits.

Background: Antimicrobial stewardship (AMS) is imperative in addressing the menace of antimicrobial resistance (AMR) in health systems. Commonwealth Partnerships for Antimicrobial Stewardship uses a health partnership model to establish AMS in Commonwealth countries. The Hospital of Kwame Nkrumah University of Science and Technology in partnership with Ulster University, Northern Ireland, undertook an AMS project from November 2021 to May 2022. We report on implementation of the AMS, its impact on antibiotic use and infections management at the University Hospital; Kumasi, Ghana. Methods: The Global-Point Prevalence Survey (PPS) protocol was used to assess antibiotics use at the hospital at baseline, midpoint and end of the project. Feedback on each PPS was given to the hospital to inform practice, behavioural change and improve antibiotic use. Results: Antibiotic use reduced from 65% at baseline to 59.7% at the end of the project. The rate of healthcare-associated infections also reduced from 17.5% at baseline to 6.5%. Use of antibiotics from the WHO Access group was 40% at baseline but increased to 50% at the endpoint. Watch antibiotics reduced from 60% to 50% from baseline. Culture and susceptibility requests increased from baseline of 111 total requests to 330 requests in the intervention period to inform antimicrobial therapy Conclusion: The model AMS instituted improved antibiotic use and quality of antimicrobial therapy within the study period. Continuous staff education and training in AMS, and use of standard tools for assessment and application of local data to inform infections management will ensure sustenance and improvement in the gains made.

(1) Background: Rational use of medicines (RUM) and their assessment are important to ensure optimal use of resources and patient care in hospitals. These assessments are essential to identifying practice gaps for quality improvement. (2) Methods: Assessment of adherence to WHO/International Network for Rational Use of Drugs core prescribing indicators among outpatients in 2021 was conducted at the University Hospital of the Kwame Nkrumah University of Science and Technology in the Ashanti Region of Ghana. We reviewed electronic medical records (EMR) of 110,280 patient encounters in the year which resulted in 336,087 medicines prescribed. (3) Results: The average number of medicines prescribed per encounter was three, with generics being prescribed in 76% of prescriptions. Injections were prescribed in 7% of encounters while 90% of medicines were from Ghana’s Essential Medicines List, 2017. (4) Conclusions: With the exception of patient encounters with injections, none of the prescribing indicators assessed in this study met WHO optimum levels, providing targets for quality improvement in RUM. Implementing prescribing guides and policies, regular audits and feedback as well as continuous professional development training may help to improve prescribing practices in the hospital.

Introduction. Rendering quality childbirth services that lead to higher levels of maternal satisfaction is an important goal of every health institution. Despite efforts at enhanced client satisfaction over the years, there are still some quality concerns for health policymakers and managers to address. This study sought to assess maternal satisfaction with childbirth services at a university hospital in Kumasi, Ghana. Methods. We conducted a facility‐based cross‐sectional study among women in postnatal wards after delivery at the University Hospital, Kwame Nkrumah University of Science and Technology. They were recruited using a systematic sampling method, and their perspective about the quality of childbirth services was assessed using a service quality (SERVQUAL) tool. Linear regression analysis was performed to identify the relationship between SERVQUAL attributes and maternal satisfaction. Statistical significance was set at p value < 0.05 at a 95% confidence interval. Results. Of the 277 participants interviewed, 79.8% (221) were satisfied with the childbirth services. Delays (49.5%), unprofessional conduct from health workers (7.2%), poor facilities (10.8%), and an inadequate number of skilled staff (15.5%) were identified as the challenges mothers encountered at the facility. After adjusting for all the components of the SERVQUAL model, reliability (adjusted β = −3.28, p = 0.001) and empathy (adjusted β = 2.21, p = 0.028) were the most significant predictors of maternal satisfaction with childbirth services. Conclusion. Majority of postnatal women were generally satisfied with the overall childbirth services they received at the University Hospital. The service quality components that significantly predicted maternal satisfaction with childbirth services were “reliability” and “empathy.”

Background: Addressing antimicrobial resistance (AMR) requires the rational use and optimization of available resources for prevention and management of infections. Structures in health facilities to support optimal antimicrobial therapy and AMR containment therefore need assessment and strengthening. Objectives: To assess antimicrobial stewardship (AMS) capacity and conformance to National and WHO Infection Prevention and Control (IPC) guidelines in three hospitals in Ashanti region of Ghana. Methods: A cross-sectional study using WHO’s hospital questionnaire for AMS capacity assessment, and Infection Prevention and Control Framework (IPCAF) to assess IPC practices in the three hospitals. Results: All the facilities had Drug and Therapeutics and IPC Committees with microbiology laboratory services. H3 and H1 did not have a formal AMS programme or an organizational structure for AMS. However, both institutions had a formal procedure to review antibiotics on prescriptions for quality assessment and relevance. H2 and H1 did not participate in any surveillance of antibiotic resistance patterns or consumption. H1 had basic, while H2 and H3 had intermediate-level IPC systems scoring 385, 487.5 and 435.8 out of 800 respectively. Conclusions: All the facilities assessed had AMS capacity and IPC conformity gaps that require strengthening to optimize antimicrobial use (AMU) and successful implementation of IPC protocols. Regular surveillance of antimicrobial consumption and microbial resistance patterns should be an integral part of activities in health institutions to generate evidence for impactful actions to contain AMR and improve AMU.
