Association between antimicrobial resistance among Enterobacteriaceae and burden of environmental bacteria in hospital acquired infections: analysis of clinical studies and national reports

The impact of enhanced cleaning on bacterial contamination of the hospital environmental surfaces: a clinical trial in critical care unit in an Egyptian hospital

BACKGROUND

Contaminated environmental surfaces play an important role in the transmission of pathogens that cause healthcare acquired infection (HAI). The present study aimed to assess the effect of enhanced cleaning techniques on bacterial contamination in high-touch areas compared to routine cleaning at the intensive care units (ICU) of the neurosurgery department of Alexandria Main University Hospital, Egypt.

METHODS

The assessment of the knowledge and practices of healthcare cleaning workers and nurses was conducted through a questionnaire and an observational checklist. An educational program about enhanced cleaning was carried out for healthcare cleaning workers and nurses in one room of the ICU unit. Environmental surface swabs were taken from the two rooms of the ICU before and after cleaning (room A and room B). Room A was selected to apply the enhanced cleaning, and room B was selected for routine cleaning.

RESULTS

A significant decrease in bacterial counts in the high-touch areas around the patients after the application of enhanced cleaning compared to routine cleaning (p < 0.001) was observed. Gram-negative bacteria isolated from high-touch areas accounted for 45.6% of the samples collected before enhanced cleaning, and they became 16.3% after enhanced cleaning (p < 0.001), while they accounted for 40% after routine cleaning. The enhanced cleaning intervention in Room A resulted in a significant reduction in total infections, decreasing from 18 cases in the six months prior to the intervention to 11 cases in the six months following its implementation. (p < 0.05).

CONCLUSION

The effect of enhanced cleaning was evident in decreasing bacterial counts in the high-touch areas around the patient and consequently in the records of the HAI rate inside the ICU.

Striving for Improved Infection Prevention and Control Practice: A Grounded Theory of Healthcare Workers' Struggles in Implementing Infection Prevention and Control Guidance in Uganda

There is a scarcity of qualitative research focusing on the implementation of infection prevention and control (IPC) guidance in low-income countries. This study aimed to address this gap by exploring the perspectives of healthcare workers (HCWs) regarding the implementation of IPC guidance at the healthcare facility level in Uganda. The study also sought to generate a theoretical understanding of the processes involved in implementing IPC guidance in these settings. This robust qualitative research employed a design based on constructivist grounded theory methodology, conducting individual interviews with 13 frontline health workers such as doctors, nurses, nurse interns, and laboratory staff. The key findings of the study revealed that HCWs undergo a process of 'striving for improved practice' in their efforts to implement IPC guidance. This process involved four phases: recognising the importance of IPC, playing a role, encountering challenges, and overcoming challenges. However, achieving full implementation proved difficult due to various individual and organisational barriers presented by the low-income setting. HCWs employed improvisation as a means to overcome these obstacles. Additionally, the study identified enabling factors that facilitated the implementation of IPC guidance within these settings. This study is significant as it applies robust qualitative research methods to provide valuable evidence of HCWs' perspectives on an important topic in an under-researched context, with findings transferable to similar settings.

National Surveillance of Antimicrobial Susceptibility of Bacteremic Gram-Negative Bacteria with Emphasis on Community-Acquired Resistant Isolates: Report from the 2019 Surveillance of Multicenter Antimicrobial Resistance in Taiwan (SMART)

A multicenter collection of bacteremic isolates of Escherichia coli (n = 423), Klebsiella pneumoniae (n = 372), Pseudomonas aeruginosa (n = 300), and Acinetobacter baumannii complex (n = 199) was analyzed for susceptibility. Xpert Carba-R assay and sequencing for mcr genes were performed for carbapenem- or colistin-resistant isolates. Nineteen (67.8%) carbapenem-resistant K. pneumoniae (n = 28) and one (20%) carbapenem-resistant E. coli (n = 5) isolate harbored bla _KPC (n = 17), bla _OXA-48 (n = 2), and bla _VIM (n = 1) genes.
