ABSTRACT
Background: Healthcare-associated infections (HAIs) are increasing in health facilities in Mali, due to health disparities and growing costs. Twenty to fifty percent of HAIs in the surgery department can be prevented with appropriate measures. Objectives: This study aimed to determine the burden of HAI and its risk factors. Materials and Methods: This was a prospective cohort study from January to June 2021 at the CHU Gabriel TOURE, Bamako, Mali. The sample size was determined based on the CDC Atlanta criteria, used to confirm HAI in surgical settings. Demographic, clinical, and biological parameters were determined. For the confirmed case of infection, the incriminated bacteria were isolated and tests were performed for the choice of drugs. Results: Of the total 1001 patients included in this study, 195 patients (19.48%) have HAIs. The types of infections were as follows: 70 cases of surgical site infections, 54 infections on burns victims, 40 urinary tract infections, and 31 cases of bacteraemia. Germs such as Escherichia Coli, Klebsiella pneumoniae, and Acinetobacter were often isolated. We found increasing hospital stays as well as some postoperative mortality related to infections. At the end of this study, corrective efforts were implemented to prevent HAI. Among them are improvements in sterilisation techniques as far as surgical materials were concerned. In addition to a surgical checklist, locally used drapes were replaced with single-use surgical supplies. Advanced training of the surgical team on things such as bladder catheterisation was also conducted in the department. It is important to put in place a committee, to prevent nosocomial infection in our hospital. The selected committee will be responsible for planning and implementing diverse strategies to prevent infections. Conclusions: The prevention of HAIs will reduce health costs and improve the quality of surgical care.
ABSTRACT
An infection is said to be nosocomial or hospital if it is absent when the patient enters the hospital and it appears and develops at least 48 h late. The objective of this study was to determine the resistance phenotypes of bacteria isolated from nosocomial infections at the University Teaching Hospital of Point G. Urine, blood, pus, skin and bronchoalveolar fluid samples were taken in different units, and bacteria isolations were performed on usual selective media such as Drigalski Colombia agar supplemented with nalidixic acid and colistin and 5% sheep blood and chocolate agar. Identifications of bacteria such as Enterobacteriaceae, Pseudomonas and acinetobacter, and Staphylococci were done using API20E gallery, API20NE gallery and catalase/oxidase tests, and the Pastorex Staph kit respectively. The antimicrobial susceptibility testing was performed on Mueller-Hinton agar using the diffusion method. A total of 463 patients were inpatients for at least 48 h in the different units, and a nosocomial infection was notified in at least 57 patients (12.3%). A total of 65 episodes of nosocomial infections were observed in these 57 patients. Of the bacteria isolated, multidrug-resistant bacteria (MDR) represented 63.7% (n=36). These were extended-spectrum beta-lactamase (ESBL)-secreting Enterobacteriaceae (n=21), high-level cephalosporinase (n=13) and methicillin-resistant coagulase-negative Staphylococci (n=2). Despite this high number of multi-resistant bacteria isolated in this study; colistin and amikacin had very good activity on enterobacteriaceae. The results show the need to strengthen hygiene in the intensive care units in order to fight against nosocomial infections at the UTH of Point G.
