Surgical site infections (SSIs) are common postoperative complications. Surgical antibiotic prophylaxis (SAP) can prevent the occurrence of SSIs if administered appropriately. We carried out a retrospective cohort study to determine the incidence of SSIs and assess whether SAP were administered according to WHO guidelines for Caesarean section (CS) and herniorrhaphy patients in Bo regional government hospital from November 2019 to October 2020. The analysis included 681 patients (599 CSs and 82 herniorrhaphies). Overall, the SSI rate was 6.7% among all patients, and 7.5% and 1.2% among CS patients and herniorrhaphy patients, respectively. SAP was administered preoperatively in 85% of CS and 70% of herniorrhaphy patients. Postoperative antibiotics were prescribed to 85% of CS and 100% of herniorrhaphy patients. Ampicillin, metronidazole, and amoxicillin were the most commonly used antibiotics. The relatively low rate of SSIs observed in this study is probably due to improved infection prevention and control (IPC) measures following the Ebola outbreak and the current COVID-19 pandemic. A good compliance rate with WHO guidelines for preoperative SAP was observed. However, there was a high use of postoperative antibiotics, which is not in line with WHO guidelines. Recommendations were made to ensure the appropriate administration of SAP and reduce unnecessary use of antibiotics.

Nasopharyngeal carriage of aerobic Gram-negative bacilli (GNB) may precede the development of invasive respiratory infections. We assessed the prevalence of nasopharyngeal carriage of aerobic GNB and their antimicrobial resistance patterns among healthy under-five children attending seven selected day-care centres in the Accra metropolis of the Greater Accra region of Ghana from September to December 2016. This cross-sectional study analysed a total of 410 frozen nasopharyngeal samples for GNB and antimicrobial drug resistance. The GNB prevalence was 13.9% (95% CI: 10.8–17.6%). The most common GNB were Escherichia coli (26.3%), Klebsiella pneumoniae (24.6%), and Enterobacter cloacae (17.5%). Resistance was most frequent for cefuroxime (73.7%), ampicillin (64.9%), and amoxicillin/clavulanic acid (59.6%). The organisms were least resistant to gentamicin (7.0%), amikacin (8.8%), and meropenem (8.8%). Multidrug resistance (MDR, being resistant to ≥3 classes of antibiotics) was observed in 66.7% (95% CI: 53.3–77.8%). Extended-spectrum beta-lactamase (ESBL)-producing bacteria constituted 17.5% (95% CI: 9.5–29.9%), AmpC-producing bacteria constituted 42.1% (95% CI: 29.8–55.5%), and carbapenemase-producing bacteria constituted 10.5% (95% CI: 4.7–21.8%) of isolates. The high levels of MDR are of great concern. These findings are useful in informing the choice of antibiotics in empiric treatment of GNB infections and call for improved infection control in day-care centres to prevent further transmission.

Background: Four partner notification approaches were introduced in health facilities in Côte d'Ivoire to increase human immunodeficiency virus (HIV) testing uptake among the type of contacts (sex partners and biological children younger than 15 years). The study assessed the 4 approaches: client referral (index cases refer the contacts for HIV testing), provider referral (health care providers refer the contacts), contract referral (index case-provider hybrid approach), and dual referral (both the index and their partner are tested simultaneously). Methods: Program data were collected at 4 facilities from October 2018 to March 2019 from index case files and HIV testing register. We compared uptake of the approaches, uptake of HIV testing, and HIV positivity percentages, stratified by contact type and gender. Results: There were 1089 sex partners and 469 children from 1089 newly diagnosed index cases. About 90% of children were contacted through client referral: 85.2% of those were tested and 1.4% was positive. Ninety percent of the children came from female index cases. The provider referral brought in 56.3% of sex partners, of whom 97.2% were HIV-tested. The client referral brought in 30% of sex partners, of whom only 81.5% were HIV-tested. The HIV positivity percentages were 75.5% and 72.7%, respectively, for the 2 approaches. Male index cases helped to reach twice as many HIV-positive sexual contacts outside the household (115) than female index cases (53). The contract and dual referrals were not preferred by index cases. Conclusions: Provider referral is a successful and acceptable strategy for bringing in sex partners for testing. Client referral is preferred for children.

Hand hygiene is the most important intervention for preventing healthcare-associated infections and can reduce preventable morbidity and mortality. We described the changes in hand hygiene practices and promotion in 13 public hospitals (six secondary and seven tertiary) in the Western Area of Sierra Leone following the implementation of recommendations from an operational research study. This was a “before and after” observational study involving two routine cross-sectional assessments using the WHO hand hygiene self-assessment framework (HHSAF) tool. The overall mean HHSAF score changed from 273 in May 2021 to 278 in April 2023; it decreased from 278 to 250 for secondary hospitals but increased from 263 to 303 for tertiary hospitals. The overall mean HHSAF score and that of the tertiary hospitals remained at the “intermediate” level, while secondary hospitals declined from “intermediate” to “basic” level. The mean score increased for the “system change” and “institutional safety climate” domains, decreased for “training and education” and “reminders in the workplace” domains, and remained the same for the “evaluation and feedback” domain. Limited resources for hand hygiene promotion, lack of budgetary support, and formalized patient engagement programs are the persistent gaps that should be addressed to improve hand hygiene practices and promotion.

Surgical site infections (SSIs) are a major public health threat to the success of surgery. This study assessed changes in SSIs and use of antibiotics among caesarean section (CS) and herniorrhaphy patients at a regional hospital in Sierra Leone following operational research. This was a comparative before and after study using routine hospital data. The study included all the CS and herniorrhaphy patients who underwent surgery between two time periods. Of the seven recommendations made in the first study, only one concerning improving the hospital’s records and information system was fully implemented. Three were partially implemented and three were not implemented. The study population in both studies showed similar socio-demographic characteristics. The use of postoperative antibiotics for herniorrhaphy in both studies remained the same, although a significant increase was found for both pre- and postoperative antibiotic use in the CS patients, 589/596 (98.8%) in 2023 and 417/599 (69.6%) in 2021 (p < 0.001). However, a significant decrease was observed in the overall incidence of SSIs, 22/777 (2.8%) in 2023 and 46/681 (6.7%) in 2021 (p < 0.001), and the incidence of SSIs among the CS patients, 15/596 (2.5%) in 2023 and 45/599 (7.5%) in 2021 (p < 0.001). The second study highlights the potential value of timely assessment of the implementation of recommendations following operational research.

Setting: The Democratic Republic of Congo suffers from an amalgam of disease outbreaks and other medical emergencies. An efficient response to these relies strongly on the national surveillance system. The Pool d'Urgence Congo (PUC, Congo Emergency Team) of Médecins Sans Frontières is a project that responds to emergencies in highly remote areas through short-term vertical interventions, during which it uses the opportunity of its presence to reinforce the local surveillance system. Objective: To investigate whether the ancillary strengthening of the peripheral surveillance system during short-term interventions leads to improved disease notification. Design: A descriptive paired study measuring disease notification before and after 12 PUC interventions in 2013–2014. Results: A significant increase in disease notification was observed after seven mass-vaccination campaigns and was sustained over 6 months. For the remaining five smaller-scaled interventions, no significant effects were observed. Conclusion: The observed improvements after even short-term interventions underline, on the one hand, how external emergency actors can positively affect the system through their punctuated actions, and, on the other hand, the dire need for investment in surveillance at peripheral level.
