Implementation of World Health Organization Guidelines in the Prevention of Surgical Site Infection in Low- and Middle-Income Countries:What We Know and Do Not Know

Scalability and Sustainability of a Surgical Infection Prevention Program in Low-Income Environments

Importance

Surgical infections are a major cause of perioperative morbidity and mortality, particularly in low-resource settings. Clean Cut, a 6-month quality improvement program developed by the global nonprofit organization Lifebox, has demonstrated improvements in postoperative infectious complications. However, the pilot program required intense external programmatic and resource support.

Objective

To examine the improvement in adherence to infection prevention and control standards and rates of postoperative infections in hospitals in the Clean Cut program after implementation strategies were updated and program execution was refined.

Design, Setting, and Participants

This cohort study evaluated and refined the Clean Cut implementation strategy to enhance scalability based on a qualitative study of its pilot phase, including formalizing programmatic and educational materials, building an automated data entry and analysis platform, and reorganizing hospital-based team composition. Clean Cut was introduced from January 1, 2019, to February 28, 2022, in 7 Ethiopian hospitals that had not previously participated in the program. Prospective data initiated on arrival in the operating room were collected, and patients were followed up through hospital discharge and with 30-day follow-up telephone calls.

Exposure

Implementation of the refined Clean Cut program.

Main Outcomes and Measures

The primary outcome was surgical site infection (SSI); secondary outcomes were adherence to 6 infection prevention standards, mortality, hospital length of stay, and other infectious complications.

Results

A total of 3364 patients (mean [SD] age, 26.5 [38.0] years; 2196 [65.3%] female) from 7 Ethiopian hospitals were studied (1575 at baseline and 1789 after intervention). After controlling for confounders, the relative risk of SSIs was reduced by 34.0% after program implementation (relative risk, 0.66; 95% CI, 0.54-0.81; P < .001). Appropriate Surgical Safety Checklist use increased from 16.3% to 43.0% (P < .001), surgeon hand and patient skin antisepsis improved from 46.0% to 66.0% (P < .001), and timely antibiotic administration improved from 17.8% to 39.0% (P < .001). Surgical instrument (38.7% vs 10.2%), linen sterility (35.5% vs 12.8%), and gauze counting (89.2% vs 82.5%; P < .001 for all comparisons) also improved significantly.

Conclusions and Relevance

A modified implementation strategy for the Clean Cut program focusing on reduced external resource and programmatic input from Lifebox, structured education and training materials, and wider hospital engagement resulted in outcomes that matched our pilot study, with improved adherence to recognized infection prevention standards resulting in a reduction in SSIs. The demonstration of scalability reinforces the value of this SSI prevention program.

Incidence, Bacterial Profile and Predictors of Surgical Site Infection After Cesarean Section in Ethiopia, A Prospective Cohort Study

Background

Surgical site infections (SSI) after cesarean section are common in Ethiopia and result in maternal morbidity, mortality, hospitalization, and medical costs. This study aimed to determine the incidence, bacterial profile, and associated factors of surgical site infection after cesarean section (CS) in public and private referral hospitals.

Methods

A prospective observational cohort study was conducted on 741 pregnant women who underwent CS from July to September 2022. Women who had CS were followed up for at least 30 days. Infected wound specimens from those who had SSIs were collected and bacteriologically analyzed. The data were analyzed with SPSS version 25. The logistic regression model assessed the relationship between the independent variable and the outcome with 95% confidence interval.

Results

The incidence of post-cesarean surgical site infection was 11.6% (95% Cl: 9.4, 13.6). Staphylococcus aureus was the most common bacteria in CS wounds 10 (21.2%). Two to three antenatal care visits (ANC) (AOR: 3.11, 95% CI: 1.69, 5.75), delayed antenatal booking (AOR: 6.99, 95% CI: 2.09, 23.32), membrane rupture (AOR: 2.10, 95% CI: 1.04, 4.24), multiple vaginal examinations (AOR = 4.21, 95% CI: 1.35, 6.92) and public hospitals (AOR: 11.1, 95% CI: 1.48, 45, 14) were associated with increased risk of SSI after CS, in contrary shorter hospital stays (AOR = 0.37, 95% CI: 0.15, 0.91) and transversal incisions (AOR = 0.38, 95% CI: 0.15, 0.91) were associated with lower risk SSI after CS.

Conclusion

The incidence of SSI after CS was high. Delayed antenatal booking, two to three antenatal visits, multiple vaginal exams, membrane rupture, vertical incision, longer postoperative hospital stays, and procedures in public hospitals were associated with increased risk of SSI after CS. Therefore, intervention programs should focus on post-discharge surveillance and identification of risk to reduce and prevent SSI after CS rate.

Components of Existing National Surgical Site Infection Surveillance Programs Based on a Case Series of Low- and Middle-Income Countries: Building Blocks for Success and Opportunities for Improvement

Background: Surgical site infection (SSI) surveillance programs are recommended to be included in national infection prevention and control (IPC) programs, yet few exist in low- or middle-income countries (LMICs). Our goal was to identify components of surveillance in existing programs that could be replicated elsewhere and note opportunities for improvement to build awareness for other countries in the process of developing their own national surgical site infection surveillance (nSSIS) programs. Methods: We administered a survey built upon the U.S. Centers for Disease Control and Prevention's framework for surveillance system evaluation to systematically deconstruct logistical infrastructure of existing nSSIS programs in LMICs. Qualitative analyses of survey responses by thematic elements were used to identify successful surveillance system components and recognize opportunities for improvement. Results: Three respondents representing countries in Europe and Central Asia, sub-Saharan Africa, and South Asia designated as upper middle-income, lower middle-income, and low-income responded. Notable strengths described by respondents included use of local paper documentation, staggered data entry, and limited data entry fields. Opportunities for improvement included outpatient data capture, broader coverage of healthcare centers within a nation, improved audit processes, defining the denominator of number of surgical procedures, and presence of an easily accessible, free SSI surveillance training program for healthcare workers. Conclusions: Outpatient post-surgery surveillance, national coverage of healthcare facilities, and training on how to take local SSI surveillance data and integrate it within a broader nSSIS program at the national level remain areas of opportunities for countries looking to implement a nSSIS program.

Impact of an educational intervention on WHO surgical safety checklist and pre-operative antibiotic use at a referral hospital in southwestern Uganda

INTRODUCTION

The World Health Organization (WHO) recommends adherence to its surgical safety checklist (SSC) to optimize patient safety and reduce cesarean surgical site infection (SSI). Educational interventions combined with audit and feedback mechanisms on the checklist use by clinicians have the potential to improve adherence and clinical outcomes. Despite the increase in cesarean delivery rates, there is a paucity of data on how such interventions can improve adherence in resource-limited settings.

OBJECTIVE

We performed a quality improvement project to measure the impact of an educational intervention with daily audit and feedback procedures on rates of WHO SSC adherence, including pre-operative antibiotic administration and SSI at Mbarara Regional Referral Hospital maternity ward in Uganda.

METHODS

The study involved chart abstraction of WHO SSC and pre-operative antibiotic use during cesarean deliveries and signs of subsequent SSI in three phases. First, we conducted a retrospective review of all charts from May to June 2018 (pre-intervention phase). Second, we instituted an educational intervention on the WHO SSC and pre-operative antibiotics use, followed by a daily audit of charts and feedback to clinicians from July to August 2018 (the intervention phase). Third, we reviewed charts from September to October 2018 (the post-intervention phase). The WHO SSC adherence, pre-operative antibiotic administration and SSI rates were measured as the proportion of the total cesarean deliveries per study phase and then compared across the three phases.

RESULTS

We reviewed 678 patients' charts (200 in the pre-intervention phase, 230 in the intervention phase and 248 in the post-intervention phase). The mean patient age was 25 years. The use of the WHO SSC was 7% in the pre-intervention phase compared to 92% in the intervention phase (P < 0.001), and 77% in the post-intervention phase (P < 0.001). Pre-intervention antibiotic receipt was 18% compared to 90% in the intervention phase (P < 0.001) and 84% in the post-intervention phase (P < 0.001). The documented SSI rate in the pre-intervention phase was 15% compared to 7% in the intervention phase (P = 0.02) and 11% in the post-intervention phase (P = 0.20).

CONCLUSIONS

An educational intervention, daily audit and feedback to clinicians increased the use of the WHO SSC and prophylactic antibiotics for cesarean delivery-although the rates waned with time. Research to understand factors influencing the checklist use and antibiotic prophylaxis including prescriber knowledge, motivation and clinical process is required. Implementation interventions to sustain usage and impact on clinical outcomes need to be explored.

Current practices and evaluation of barriers and facilitators to surgical site infection prevention measures in Jimma, Ethiopia

Objective:

Surgical site infections (SSIs) greatly burden healthcare systems around the world, particularly in low- and middle-income countries. We sought to employ the Systems Engineering Initiative for Patient Safety (SEIPS) model to better characterize SSI prevention practices and factors affecting adherence to prevention guidelines at Jimma University Medical Center (JUMC).

Design:

Our cross-sectional study consisted of semistructured interviews designed to elicit perceptions of and barriers and facilitators to SSI prevention among surgical staff and observations of current preoperative, perioperative, and postoperative SSI prevention practices in surgical cases. Interviews were recorded, manually transcribed, and thematically coded within the SEIPS framework. Trained observers recorded compliance with the World Health Organization’s SSI prevention recommendations.

Setting:

A tertiary-care hospital in Jimma, Ethiopia.

Participants:

Surgical nurses, surgeons, and anesthetists at JUMC.

Results:

Within 16 individual and group interviews, participants cited multiple barriers to SSI prevention including shortages of water and antiseptic materials, lack of clear SSI guidelines and training, minimal Infection Prevention Control (IPC) interaction with surgical staff, and poor SSI tracking. Observations from nineteen surgical cases revealed high compliance with antibiotic prophylaxis (94.7%), hand scrubbing (100%), sterile gloves and instrument use (100%), incision site sterilization (100%), and use of surgical safety checklist (94.7%) but lower compliance with preoperative bathing (26.3%), MRSA screening (0%), and pre- and postoperative glucose (0%, 10.5%) and temperature (57.9%, 47.3%) monitoring.

Conclusions:

Utilizing the SEIPS model helped identify institution-specific barriers and facilitators that can inform targeted interventions to increase compliance with currently underperformed SSI prevention practices at JUMC.

Improving sterile processing practices in Cambodian healthcare facilities

Background

Sterile processing practices in low-resource countries contribute to greater post-operative infection rates compared to high-resource countries. Provision of a sterile processing training program in Tanzania and Ethiopia demonstrated statistically significant improvements in sterile processing practice, a key requisite for safe surgical care.

Aim

To determine if a sterile processing program in a South East Asia country would result in improved conditions and practice in urban and rural healthcare facilities.

Methods

In 2019, a mixed-methods study was conducted with two cohorts in Cambodia, involving a total of eight healthcare facilities and 43 healthcare workers. Quantitative data were collected using a sterile processing assessment tool and a multiple-choice test pre- and post-training. Qualitative data in the form of interviews were obtained several months post-training.

Findings

Test results showed statistically significant and sustained effect of training over a four-six month period, as well as a large positive effect on SP knowledge in both cohorts. Analysis of hospital assessment data revealed an aggregate improvement of 36% in sterile processing benchmarks. While all participants reported increased knowledge and confidence (quantitative), rural participants conveyed a lack of support (qualitative) to implement practice changes.

Conclusion

The training course produced improvements in both rural and urban facilities. Findings highlight the importance of informing administrators of the rationale for needed improvements, ensuring funding is available to implement recommendations, and for governments to hold administrators accountable for improvements aligning with universally recommended sterile processing standards.
