This study aimed to investigate the presence of Gram-negative and Gram-positive bacteria on handheld shopping trolleys and baskets and their antimicrobial susceptibility status against commonly used antibiotics in Zambia. Methods: A cross-sectional study was conducted. Trolleys and basket handles were swabbed and standard microbiological methods were used to identify the bacteria and disc diffusion to determine their antimicrobial susceptibility status. Data was collected from December 2021 to April 2022. Data was analysed using IBM Statistical Package for Social Sciences (SPSS) Version 22. Results: Twenty-eight percent of the 200 total samples were found to be culture-positive and predominant isolates were Staphylococcus aureus (17.3%), Pseudomonas species (4.5%), Escherichia coli (2%), Corynebacterium species (2%), Staphylococcus species (1.5%) and Enterobacter aerogenes (0.5%). Staphylococcus aureus showed the most resistance to azithromycin (17%) followed by ciprofloxacin (2.8%), nitrofurantoin (2.8%) and chloramphenicol (2.8%). Escherichia coli showed 100% resistance to amoxicillin, cloxacillin and ampicillin, 75% resistance to ciprofloxacin and the least resistance to azithromycin (25%) while it was susceptible to nitrofurantoin. Staphylococcus species, Corynebacterium species, Enterobacter aerogenes and Pseudomonas species showed no resistance to any antibiotics. Conclusion: The study showed the presence of microorganisms with considerable antimicrobial resistance to antibiotics in Zambia on trolley and basket handles indicating the need for more initiatives to address proper hygiene in public environmental sites for better infection prevention and control.展开更多

A quantitative and descriptive research design was used for the study to investigate emergency equipment, essential drugs and emergency trolleys. A convenient sample of 10 emergency trolleys in the Windhoek Central Hospital (Hospital A) and Katutura Intermediate Hospital (Hospital B) in Windhoek, Namibia were used. Data was collected using a checklist adapted and edited from the EMSSA. Data were analysed using Microsoft excel 2013. Essential paediatric equipment including bag valve mask devices, Magill’s forceps, oxygen masks were absent in many of the units and wards. Data described that checking of defibrillators, monitors and suction devices still remained a major problem in the units/wards that were fortunate enough to have the aforementioned equipment. A conclusion was that generally the units/wards performed well during the assessments and evaluations. There were still units without emergency trolleys, trolleys that were poorly assessed, and those that were obstructed and registered nurses that had a negative perception to the audit of the emergency trolley. Specialized units such as NICU and Hi-Care Hospital A and Prem Unit Hospital B performed very well in their assessments. Development of policy with regards to assessing, restocking and maintenance of emergency supplies can be used to guide the nurses on what to do. Resuscitation morbidity and mortality meetings in order to identify issues and outcomes surround resuscitation incidences within the unit or ward.展开更多
