Excessive and inappropriate use of antibiotics in hospitalised patients contributes to the development and spread of antibiotic resistance. Implementing a stewardship programme to curb the problem requires information on antibiotic use. This study describes a multicentre point prevalence of antibiotic use among paediatric inpatients in Ghana. Data were extracted from a multicentre point prevalence survey of hospital acquired infections in Ghana. Data were collected between September 2016 and December 2016 from ten hospitals through inpatient folder and chart reviews using European Centre for Disease Control (ECDC) adapted data collection instrument. From each site, data were collected within a 12-h period (8 am to 8 pm) by a primary team of research investigators and a select group of health professionals from each participating hospital. Among 716 paediatric inpatients, 506 (70.6%; 95% confidence interval (CI): 67.2 to 74.0%) were on antibiotics. A significant proportion of antibiotics (82.9%) was prescribed for infants compared to neonates (63.9%) and adolescents (60.0%). The majority of patients (n = 251, 49.6%) were prescribed two antibiotics at the time of the survey. The top five classes of antibiotics prescribed were third generation cephalosporins (n = 154, 18.5%) aminoglycosides (n = 149, 17.9%), second generation cephalosporins (n = 103,12.4%), beta lactam resistant penicillins (n = 83, 10.0%) and nitroimidazoles (n = 82, 9.9%). The majority of antibiotics (n = 508, 61.0%) were prescribed for community acquired infections. The top three agents for managing community acquired infections were ceftriaxone (n = 97, 19.1%), gentamicin (n = 85, 16.7%) and cefuroxime (n = 73, 14.4%). This study points to high use of antibiotics among paediatric inpatients in Ghana. Cephalosporin use may offer an important target for reduction through antibiotic stewardship programmes.

Improper use of antibiotics leads to the emergence of resistant microorganisms as well as drug toxicity, increased healthcare costs, morbidity and mortality. Globally, an estimated 25–68% of hospitalized patients receive suboptimal antibiotic regimes. Information on the extent of this problem in Ghana is currently limited, particularly in surgical units. To strategize for interventions, we estimated the antibiotic use prevalence in surgical departments in a country-wide point prevalence survey (PPS) in Ghana. Between October 2016 and December 2016, we conducted a cross-sectional multi-center country-wide PPS. This involved an audit of in-patients’ records from all units/departments of ten systematically selected hospitals in Ghana. Data were collected with a standardized questionnaire, adopted from the European Centre for Disease Prevention and Control. In this report, we present data on antibiotic use from the surgical units. Of 2107 eligible patients included in the PPS, 540 patients were identified in surgical units, of which 70.7% (382/540) received antibiotic therapy. A total of 636 antibiotic prescriptions were issued to these surgical patients; 224 (58.6%) for treatment, including 50 for treatment of hospital-acquired infections, and 144 (37.7%) for prophylaxis (medical and surgical). Median duration of antibiotic therapy prior to the survey was 5 days (interquartile range (IQR): 3-8 days). Surgical prophylaxis was administered for longer than the recommended one day in 107 of 144 (88.4%) patients. The choice of antibiotics was largely similar for community- and hospital-acquired infections as well as for prophylaxis. Only 3.7% of patients had microbiological analysis done on clinical samples. We found a high prevalence of antibiotic use, with the choice of antibiotics, in some cases, inconsistent with the country’s treatment guidelines. Antibiotics were administered for long duration including antibiotics for prophylactic purposes and the majority was started without supporting microbiological analysis. Prescription practices that encourage rational use of antibiotics guided by microbiology and enforcement of antibiotic policy guidelines should be the target for future interventions.

Background: There is limited data to guide the prevention and management of surgical site infections (SSI) in low- and middle-income countries. We prospectively studied aetiological agents associated with SSI and their corresponding antibiotic susceptibility patterns in a tertiary hospital in Ghana. Methods: As part of a cohort study carried out at the surgical department of the Korle Bu Teaching Hospital (KBTH) from July 2017 to April 2019, wound swabs were collected from patients diagnosed with SSI. Isolates cultured from the wound swabs were identified by MALDI TOF and susceptibility testing was conducted according to EUCAST 2020 guidelines. Clinical data were monitored prospectively. Results: Of 4577 patients, 438 developed an SSI and 352 microbial isolates were cultured. Isolates were predominantly Gram negative (286, 81%), a pattern seen for all kinds of surgery and all wound classes. The most common species included Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus and Acinetobacter baumannii. The majority of organisms were multi-drug resistant including 86% of E. coli, 52% of A. baumannii and 86% of K. pneumoniae; and 65% (17/26) of the cefotaxime-resistant K. pneumoniae were extended spectrum β-lactamase producing. One of 139 E. coli, 15 of 49 P. aeruginosa, and 6 of 23 A. baumannii were meropenem resistant, but no clonal pattern was found. There was a 1% (5/428) prevalence of methicillin-resistant S. aureus. Conclusions: The predominance of Gram-negative organisms and the high level of multi-drug resistance indicate a need to re-evaluate antibiotic prophylaxis and treatment protocols in surgical practice in low- and middle-income countries.

Surgical instruments, be they disposable or reusable, are essential in any surgical procedure. Reusable surgical instruments should be properly sterilized or disinfected before use. However, the protocols are not always followed accordingly. This results in sterilization and disinfection failures, leading to a possible increase in the incidence of surgical site infections. This observational study report on bacterial contaminants identified instruments used for surgical procedures in a major teaching hospital in a resource-limited country. In total, 207 pre-sterilized surgical instruments and instrument parts used at three units—the general surgical theater, and the gastrointestinal (GI) endoscopy and urology endoscopy (uro-endoscopy) units—within the surgical department were randomly sampled and examined for bacterial contamination. Bacteria isolates were identified, and their antimicrobial susceptibility patterns were determined. Bacteria isolates that were identified included Citrobacter spp., Citrobacter freundii, Bacillus cereus, Staphylococcus hominis, and Staphylococcus aureus. Bacillus cereus was the most predominant bacteria isolated (30/61, 49.1%), and Staphylococcus hominis the least (1/61, 1.6%). In terms of the number of isolates from the three units examined, the uro-endoscopy unit recorded the highest followed by the general surgical theater and the GI endoscopy. However, there was no association between the various units and bacteria isolated, and no significant difference between the number of isolates among the various units (p = 0.9467, χ2 = 0.1095). In this study, even though CFU per device or device part counted was less than 20, bacteria isolated from the instruments used for a surgical procedure is of great concern considering that the setting of the study is a major teaching hospital. Multi-drug resistance was observed in almost all the isolated bacteria. Sterilization processes should be strictly adhered to, taking into consideration the length and temperature in order to reduce the risk of using contaminated instruments in these environments. It is therefore recommended that similar studies should be carried out in surgical departments at different levels of hospitals to ascertain the extent of this problem.

Major surgery carried out in low- and middle-income countries is associated with a high risk of surgical site infections (SSI), but knowledge is limited regarding contributory factors to such infections. This study explores factors related to patients developing an SSI in a teaching hospital in Ghana. A prospective cohort study of patients undergoing abdominal surgical procedures was conducted at Korle Bu Teaching Hospital. Patient characteristics, procedures and environmental characteristics were recorded. A 30-day daily surveillance was used to diagnose SSI, and Poisson regression analysis was used to test for association of SSI and risk factors; survival was determined by proportional hazard regression methods. We included 358 patients of which 58 (16.2%; 95% CI 12.7–20.4%) developed an SSI. The median number of door openings during an operation was 79, with 81% being unnecessary. Door openings greater than 100 during an operation (P = 0.028) significantly increased a patient's risk of developing an SSI. Such patients tended to have an elevated mortality risk (hazard ratio 2.67; 95% CI 0.75–9.45, P = 0.128). We conclude that changing behaviour and practices in operating rooms is a key strategy to reduce SSI risk.
