Magnitude of standard precautions practices among healthcare workers in health facilities of Low and Middle Income Countries: A systematic review and meta-analysis

BACKGROUND

Standard precautions are the minimum standard of infection control to prevent transmission of infectious agents, protect healthcare workers, patients, and visitors regardless of infection status. The consistent implementation of standard precautions is highly effective in reducing transmission of pathogens that cause HAIs. Despite their effectiveness, compliance, resources, patient behavior, and time constraints are some of the challenges that can arise when implementing standard precautions. The main objective of this meta-analysis was to show the pooled prevalence of safe standard precaution practices among healthcare workers in Low and Middle Income Countries (LMICs).

METHODS

A systematic review and meta-analysis was conducted for this study. We systematically searched observational study articles from PubMed Central and Google Scholar. We included articles published any year and involving healthcare workers. We used Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). The random effect model was used to estimate the pooled prevalence. The meta-analysis, sensitivity analysis, subgroup analysis, and publication bias (funnel plot, and Egger's tests) were conducted.

RESULTS

A total of 46 articles were included in this study. The pooled prevalence of standard precautions practices among healthcare workers in LMICs was 53%, with a 95% CI of (47, 59). These studies had a total sample size of 14061 with a minimum sample size of 17 and a maximum sample size of 2086. The majority of the studies (82.6%) were conducted in hospitals only (all kinds), and the remaining 17.4% were conducted in all health facilities, including hospitals.

CONCLUSIONS

The pooled prevalence of standard precautions practices among healthcare workers in LMICs was suboptimal. The findings of this study can have substantial implication for healthcare practice and policy making by providing robust evidence with synthesized and pooled evidence from multiple studies.

Silver-Polymethylhydrosiloxane-Quaternary Ammonium Coating on Anodized Aluminum with Excellent Antibacterial Property

Multidrug-resistant bacteria are known to survive on high-touch surfaces for days, weeks, and months, contributing to the rise in nosocomial infections. Inducing antibacterial property in such surfaces can presumably reduce the overall microbial burden and subsequent nosocomial infections in hygiene critical environments. In the present study, a one-pot sol-gel process has been deployed to incorporate silver (Ag) and quaternary ammonium salt (QUAT) bactericides in a polymethylhydrosiloxane (PMHS) matrix. The Ag-PMHS-QUAT nanocomposite was coated on anodized aluminum (AAO/Al) by a simple ultrasound-assisted deposition process. The morphological features and chemical composition of the Ag-PMHS-QUAT nanocomposite have been characterized using SEM, XRD spectroscopy, and attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) to confirm the formation of Ag-QUAT nanocomposites within the polymeric network of PMHS. The Ag-PMHS-QUAT nanocomposite coating on anodized aluminum oxide (AAO/Al) coupon exhibited superior antibacterial property with a 6-log bacterial reduction compared to the 5-log reduction for the commercially available antimicrobial copper coupon.

Infection Prevention and Control in Three Tertiary Healthcare Facilities in Freetown, Sierra Leone during the COVID-19 Pandemic: More Needs to Be Done!

Infection Prevention and Control (IPC) measures are critical to the reduction in healthcare-associated infections, especially during pandemics, such as that of COVID-19. We conducted a hospital-based cross-sectional study in August 2021 at Connaught Hospital, Princess Christian Maternity Hospital and Ola During Children's Hospital located in Freetown, Sierra Leone. We used the World Health Organization's Infection Prevention and Control Assessment Framework Tool to assess the level of IPC compliance at these healthcare facilities. The overall IPC compliance score at Connaught Hospital was 323.5 of 800 points, 313.5 of 800 at Ola During Children's Hospital, 281 of 800 at Princess Christian Maternity Hospital, implying a 'Basic' IPC compliance grade. These facilities had an IPC program, IPC committees and dedicated IPC focal persons. However, there were several challenges, including access to safe and clean water and insufficient quantities of face masks, examination gloves and aprons. Furthermore, there was no dedicated budget or no healthcare-associated infection (HAI) surveillance, and monitoring/audit of IPC practices were weak. These findings are of concern during the COVID-19 era, and there is an urgent need for both financial and technical support to address the gaps and challenges identified.
