The 17th International Congress on Infectious Diseases workshop on developing infection prevention and control resources for low- and middle-income countries

Long-Term Sustainability of Peri-Operative Infection Control Practices: Implementation of "Clean Cut," a Checklist-Based Quality Improvement Program in India

Introduction: Surgical site infections (SSIs) are a substantial healthcare burden in low- and middle- income countries. "Clean Cut" is a checklist-based infection prevention and control (IPC) program intended to improve compliance to peri-operative IPC standards. We aim to study the short-term and long-term impact of its implementation in a tertiary care cancer referral center. Methods: This was a single institute, prospective interventional study. Patients undergoing elective head-neck surgical procedures were included. The "Clean Cut" program consisting of surveillance, audits, and IPC training was implemented for 6 months, after which there was no active oversight. Post-intervention (T2) and 1-year follow-up (T3) data regarding compliance to core IPC practices and SSI rates were compared with baseline (T1). Results: One hundred eighty six patients were included with 50 (26.9%), 86 (46.2%), and 50 (26.9%) patients at T1, T2, and T3, respectively. At baseline, teams complied with a mean of 3.56 of the six critical components of infection control processes which rose to 4.66 (p < 0.001) at T2, but decreased to 4.02 at T3 (p = 0.053). The SSI rate at baseline decreased significantly after Clean Cut implementation [16 (32%) vs. 12 (13.95%), p = 0.012], but returned to baseline levels after 1 year [17 (34%), p = 0.006]. Conclusion: Implementation of the "Clean Cut" program increases compliance to infection control processes and reduces SSI rates in the short term. Without continuing oversight, these rates return to baseline values after 1 year.

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.

Molecular characterization of carbapenem-resistance in Gram-negative isolates obtained from clinical samples at Jimma Medical Center, Ethiopia

Background

In resource-constrained settings, limited antibiotic options make treating carbapenem-resistant bacterial infections difficult for healthcare providers. This study aimed to assess carbapenemase expression in Gram-negative bacteria isolated from clinical samples in Jimma, Ethiopia.

Methods

A cross-sectional study was conducted to assess carbapenemase expression in Gram-negative bacteria isolated from patients attending Jimma Medical Center. Totally, 846 Gram-negative bacteria were isolated and identified using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Phenotypic antibiotic resistance patterns were determined using the Kirby-Bauer disk diffusion method and Etest strips. Extended-spectrum β-lactamase phenotype was determined using MAST disks, and carbapenemases were characterized using multiplex polymerase chain reactions (PCR).

Results

Among the isolates, 19% (157/846) showed phenotypic resistance to carbapenem antibiotics. PCR analysis revealed that at least one carbapenemase gene was detected in 69% (107/155) of these strains. The most frequently detected acquired genes were blaNDM in 35% (37/107), blaVIM in 24% (26/107), and blaKPC42 in 13% (14/107) of the isolates. Coexistence of two or more acquired genes was observed in 31% (33/107) of the isolates. The most common coexisting acquired genes were blaNDM + blaOXA-23, detected in 24% (8/33) of these isolates. No carbapenemase-encoding genes could be detected in 31% (48/155) of carbapenem-resistant isolates, with P. aeruginosa accounting for 85% (41/48) thereof.

Conclusion

This study revealed high and incremental rates of carbapenem-resistant bacteria in clinical samples with various carbapenemase-encoding genes. This imposes a severe challenge to effective patient care in the context of already limited treatment options against Gram-negative bacterial infections in resource-constrained settings.

Implementation fidelity of infection prevention practices at Debre Tabor comprehensive specialized hospital, Northwest Ethiopia

BACKGROUND

Healthcare-Acquired Infections are a major problem in the world and within the healthcare delivery system. An estimated 5-10% and around 25% of hospitalized patients have healthcare-acquired infections in developed and developing countries, respectively. Infection prevention and control programs have proven to be successful in lowering the incidence and spread of infections. Thus, this evaluation aims to evaluate the implementation fidelity of infection prevention practices at Debre Tabor comprehensive specialized hospital in Northwest Ethiopia.

METHODS

A facility-based cross-sectional design with a concurrent mixed method was used to evaluate the implementation fidelity of infection prevention practices. A total of 36 indicators were used to measure adherence, participant responsiveness, and facilitation strategy dimensions. A total of 423 clients were administered for an interview, an inventory checklist, a document review, 35 non-participatory observations, and 11 key informant interviews were conducted. A multivariable logistic regression analysis was used to identify factors significantly associated with the satisfaction of clients. The findings were presented using descriptions, tables, and graphs.

RESULT

The overall implementation fidelity of the infection prevention practices was 61.8%. The dimensions of adherence to infection prevention and control guidelines were 71.4%, participant responsiveness was 60.6%, and facilitation strategy was 48%. In multivariable analysis, ward admission and educational level had a p-value of below 0.05 and were significantly associated with the satisfaction of clients with infection prevention practices at the hospital. The major themes that emerged in qualitative data analysis were healthcare worker-related factors, management-related factors, and patient- and visitor-related factors.

CONCLUSION

The evaluation result of this study concluded that the overall implementation fidelity of infection prevention practice was judged to be medium and needed improvement. It included dimensions of adherence and participant responsiveness that were rated as medium, as well as a facilitation strategy that was rated as low. Enablers and barriers were thematized into factors related to healthcare providers, management, institutions, and patient and visitor relations.

Moving from assessments to implementation: promising practices for strengthening multisectoral antimicrobial resistance containment capacity

BACKGROUND

Antimicrobial resistance (AMR) poses a global threat to human, animal, and environmental health. AMR is a technical area in the Global Health Security Agenda initiative which uses the Joint External Evaluation tool to evaluate national AMR containment capacity. This paper describes four promising practices for strengthening national antimicrobial resistance containment capacity based on the experiences of the US Agency for International Development's Medicines, Technologies, and Pharmaceutical Services Program work with 13 countries to implement their national action plans on AMR in the areas of multisectoral coordination, infection prevention and control, and antimicrobial stewardship.

METHODS

We use the World Health Organization (WHO) Benchmarks on International Health Regulations Capacities (2019) to guide national, subnational, and facility actions that advance Joint External Evaluation capacity levels from 1 (no capacity) to 5 (sustainable capacity). Our technical approach is based on scoping visits, baseline Joint External Evaluation scores, benchmarks tool guidance, and country resources and priorities.

RESULTS

We gleaned four promising practices to achieve AMR containment objectives: (1) implement appropriate actions using the WHO benchmarks tool, which prioritizes actions, making it easier for countries to incrementally increase their Joint External Evaluation capacity from level 1 to 5; (2) integrate AMR into national and global agendas. Ongoing agendas and programs at international, regional, and national levels provide opportunities to mainstream and interlink AMR containment efforts; (3) improve governance through multisectoral coordination on AMR. Strengthening multisectoral bodies' and their technical working groups' governance improved functioning, which led to better engagement with animal/agricultural sectors and a more coordinated COVID-19 pandemic response; and (4) mobilize and diversify funding for AMR containment. Long-term funding from diversified funding streams is vital for advancing and sustaining countries' Joint External Evaluation capacities.

CONCLUSIONS

The Global Health Security Agenda work has provided practical support to countries to frame and conduct AMR containment actions in terms of pandemic preparedness and health security. The WHO benchmarks tool that Global Health Security Agenda uses serves as a standardized organizing framework to prioritize capacity-appropriate AMR containment actions and transfer skills to help operationalize national action plans on AMR.

An outbreak of Burkholderia cepacia bloodstream infections in a tertiary-care facility in northern India detected by a healthcare-associated infection surveillance network

OBJECTIVE

The burden of healthcare-associated infections (HAIs) is higher in low- and middle-income countries, but HAIs are often missed because surveillance is not conducted. Here, we describe the identification of and response to a cluster of Burkholderia cepacia complex (BCC) bloodstream infections (BSIs) associated with high mortality in a surgical ICU (SICU) that joined an HAI surveillance network.

SETTING

A 780-bed, tertiary-level, public teaching hospital in northern India.

METHODS

After detecting a cluster of BCC in the SICU, cases were identified by reviewing laboratory registers and automated identification and susceptibility testing outputs. Sociodemographic details, clinical records, and potential exposure histories were collected, and a self-appraisal of infection prevention and control (IPC) practices using assessment tools from the World Health Organization and the US Centers for Disease Control and Prevention was conducted. Training and feedback were provided to hospital staff. Environmental samples were collected from high-touch surfaces, intravenous medications, saline, and mouthwash.

RESULTS

Between October 2017 and October 2018, 183 BCC BSI cases were identified. Case records were available for 121 case patients. Of these 121 cases, 91 (75%) were male, the median age was 35 years, and 57 (47%) died. IPC scores were low in the areas of technical guidelines, human resources, and monitoring and evaluation. Of the 30 environmental samples, 4 grew BCC. A single source of the outbreak was not identified.

CONCLUSIONS

Implementing standardized HAI surveillance in a low-resource setting detected an ongoing Burkholderia cepacia outbreak. The outbreak investigation and use of a multimodal approach reduced incident cases and informed changes in IPC practices.

The mediating role of incentives in association between leadership attention and self-perceived continuous improvement in infection prevention and control among medical staff: A cross-sectional survey

Objectives

Promoting improvement in Infection Prevention and Control (IPC) is an important part of improving the quality of care. The influence of leadership attention and incentives on the self-perceived continuous improvement in IPC has drawn a lot of attention, but relevant academic research is still lacking. The objective of this study is to explore the effect of leadership attention on self-perceived continuous improvement in IPC among medical staff and its underlying mechanisms.

Method

The 3,512 medical staff from 239 health facilities in Hubei, China, were surveyed online during September 2020. Data on leadership attention, incentives, and improvement in Infection Prevention and Control were collected using self-administered questionnaires. Correlation analysis was used to analyze the relationship between leadership attention, incentives, and improvement in Infection Prevention and Control. Amos 24.0 was used to analyze the mediating role.

Results

The scores of leadership attention, incentives and self-perceived continuous improvement in Infection Prevention and Control were all high. The score of leadership attention was the highest (4.67 ± 0.59), followed by self-perceived continuous improvement (4.62 ± 0.59) and incentives in Infection Prevention and Control (4.12 ± 0.83). Leadership attention positively affected self-perceived continuous improvement in Infection Prevention and Control (β = 0.85, 95% CI = [0.83, 0.87]). Moreover, incentives partially mediated the effect of leadership attention on self-perceived continuous improvement in Infection Prevention and Control among medical staff (β = 0.13, 95% CI = [0.12, 0.15]).

Conclusion

Leadership attention positively affects self-perceived continuous improvement in Infection Prevention and Control among medical staff, and incentives mediates this relationship. The present study has valuable implications for self-perceived continuous improvement in Infection Prevention and Control from the perspective of leadership attention and incentives.

Pre-COVID-19 knowledge, attitude and practice among nurses towards infection prevention and control in Bangladesh: A hospital-based cross-sectional survey

INTRODUCTION

Hospital-acquired infections endanger millions of lives around the world, and nurses play a vital role in the prevention of these infections. Knowledge of infection prevention and control (IPC) best practices among nurses is a prerequisite to maintaining standard precautions for the safety of patients.

AIM

The study aims to assess knowledge, attitudes, and practices (KAP) towards IPC including associated factors among the nurses of a tertiary care hospital in Bangladesh.

METHODS

We conducted this hospital-based cross-sectional study from October 2017 to June 2018 at Dhaka Medical College Hospital among 300 nurses working in all departments. We calculated three KAP scores for each participant reflecting their current state of knowledge and compliance towards IPC measures. Descriptive, bivariate and multivariable analyses were conducted to determine KAP scores among nurses and their associated factors.

RESULTS

Average scores for knowledge, attitudes, and practices were 18.6, 5.4, and 15.5 (out of 26, 7, and 24), respectively. The study revealed that the majority (85.2%) of the nurses had a good to moderate level of knowledge, half (51%) of them showed positive attitudes, and only one fifth (17.1%) of the nurses displayed good practices in IPC. The respondents' age, education, monthly income and years of experience were found to have statistical associations with having moderate to adequate level of KAP scores. Aged and experienced nurses were found more likely to have poor knowledge and unfavorable attitude toward IPC practices.

CONCLUSION

The majority of nurses had good IPC knowledge, but their practices did not reflect that knowledge. In particular, nurses needed to improve the proper IPC practice for better patient care and to protect themselves. Regular IPC training and practice monitoring can enhance the IPC practice among nurses.

Epidemiology and Risk Factors of Healthcare-Associated Infections in Critically Ill Patients in a Tertiary Care Teaching Hospital in Nepal: A Prospective Cohort Study

Background:

Healthcare-associated infection (HAI) is an important public health problem, particularly in intensive care units (ICUs). We aimed to examine the epidemiology and risk factors of HAIs in our ICUs and study their microbiological profile.

Methods:

We evaluated 100 consecutive patients in 3 medical and surgical ICUs of a tertiary care teaching hospital daily starting in January 2016 using the Centers for Disease Control and Prevention definitions and methods. We determined the incidence and sites of HAIs, identified the causative microorganism, and studied their antibiotic sensitivity profiles. We investigated risk factors for the development of an HAI using a multiple logistic regression model.

Results:

Of 300 patients, 129 patients (43%) developed HAIs (55.96 HAI events per 1000 ICU-days). Pneumonia was the most common type of HAI (57, 41%). Escherichia coli was the most frequently isolated microorganism (20, 29%) and 74% of the pathogens isolated were multi-drug resistant. The presence of an invasive device (Odds Ratio, 4.29; 95% Confidence Interval, 2.52-7.51) and use of sedation (Odds Ratio, 2.24; 95% Confidence Interval, 1.31-3.87) were the statistically significant risk factors for HAIs.

Conclusions:

We found a high incidence of HAIs in our ICUs and a high burden of multidrug-resistant microorganisms highlighting the importance of infection control and antibiotic stewardship.

Molecular Surveillance and Dissemination of Klebsiella pneumoniae on Frequently Encountered Surfaces in South African Public Hospitals

Bacteria that cause life-threatening illnesses in humans are also capable of contaminating hospital surfaces, thus pose as a potential source of infection. This study aimed to investigate the prevalence, genetic diversity, virulence, and antibiotic resistance profile of Klebsiella pneumoniae in South Africa. In a nonoutbreak setting involving four public hospitals, 777 samples were collected in three different wards from 11 different sites. Phenotypic and genotypic methods were used for isolation and identification. The Kirby-Bauer disk-diffusion method was used to examine antibiotic resistance followed by the combination disk method to characterize extended-spectrum β-lactamases (ESBLs). Antibiotic resistance and virulence genes were screened using PCR and clonality was investigated using enterobacterial repetitive intergenic consensus (ERIC)-PCR. Seventy-five (10%) K. pneumoniae isolates were recovered. These isolates were obtained from all four hospitals and all three wards involved. However, only six frequently touched surfaces were contaminated. Thirty (40%) isolates were characterized as ESBLs showing high resistance to antibiotics and mostly harboring the bla_CTX-M group one gene. Virulence genes were highly prevalent among all the isolates. ERIC-PCR showed that the isolates recovered from different sites within the same hospital were genetically similar. The study highlighted that K. pneumoniae can contaminate various surfaces and this persistence allows for the dissemination of bacteria within the hospital environment. The information from this study can assist hospitals to evaluate and improve current infection prevention and control interventions in place.

Safer primary healthcare facilities are needed to protect healthcare workers and maintain essential services: lessons learned from a multicountry COVID-19 emergency response initiative

Healthcare workers (HCWs) are at increased risk of infection from SARS-CoV-2 and other disease pathogens, which take a disproportionate toll on HCWs, with substantial cost to health systems. Improved infection prevention and control (IPC) programmes can protect HCWs, especially in resource-limited settings where the health workforce is scarcest, and ensure patient safety and continuity of essential health services. In response to the COVID-19 pandemic, we collaborated with ministries of health and development partners to implement an emergency initiative for HCWs at the primary health facility level in 22 African countries. Between April 2020 and January 2021, the initiative trained 42 058 front-line HCWs from 8444 health facilities, supported longitudinal supervision and monitoring visits guided by a standardised monitoring tool, and provided resources including personal protective equipment (PPE). We documented significant short-term improvements in IPC performance, but gaps remain. Suspected HCW infections peaked at 41.5% among HCWs screened at monitored facilities in July 2020 during the first wave of the pandemic in Africa. Disease-specific emergency responses are not the optimal approach. Comprehensive, sustainable IPC programmes are needed. IPC needs to be incorporated into all HCW training programmes and combined with supportive supervision and mentorship. Strengthened data systems on IPC are needed to guide improvements at the health facility level and to inform policy development at the national level, along with investments in infrastructure and sustainable supplies of PPE. Multimodal strategies to improve IPC are critical to make health facilities safer and to protect HCWs and the communities they serve.

Antimicrobial Resistance in Enterobacterales and Its Contribution to Sepsis in Sub-saharan Africa

Antibiotic resistant Enterobacterales (formerly Enterobactereaceae) are a growing threat to Sub-Saharan Africa. Genes causing antibiotic resistance are easily spread between the environment and humans and infections due to drug resistant organisms contribute to sepsis mortality via delayed time to appropriate antimicrobial therapy. Additionally, second or third-line antibiotics are often not available or are prohibitively expensive in resource-constrained settings leading to limited treatment options. Lack of access to water and sanitation facilities, unregulated use of antibiotics, and malnutrition are contributors to high rates of antibiotic resistance in the region. Improvements in the monitoring of drug resistant infections and antibiotic stewardship are needed to preserve the efficacy of antibiotics for the future.

Use of "Social Media"-an Option for Spreading Awareness in Infection Prevention

Purpose of review

There is a need for enhanced adoption of infection prevention and control (IPC) practices in both healthcare settings and the entire community, more so during pandemics. The exponential increase in the use of social media (SM) has made it a powerful tool for creating awareness, education, training and community engagement on IPC. Here, we review how social media can be used effectively to implement strategies to combat public health issues especially vis-à-vis infection prevention and control.

Recent findings

According to the World Health Organization, 10% of patients get an infection whilst receiving care in healthcare institutions. Effective infection prevention and control measures can reduce healthcare-associated infections by at least 30%. Education and awareness play a vital role in implementation of infection prevention and control (IPC) strategies. Various studies show how social media has been used successfully in education and training activities, for awareness campaigns, community engagement, risk communications during outbreaks, disease surveillance and pharmacovigilance.

Summary

Infection prevention and control (IPC) is the need of the hour to mitigate transmission of disease in healthcare settings as well as in the community. SM is the fastest and most efficient way of communicating with the general population as well as health professionals. SM can help people take the right decisions and enable change in their behaviour patterns to introduce infection control practices.

Microbiological Contamination of Mobile Phones and Mobile Phone Hygiene of Final-Year Medical Students in Uganda: A Need for Educational Intervention

INTRODUCTION

Contaminated mobile phones act as reservoirs for organisms causing hospital-acquired infections (HAI). Little is known about medical school students' awareness of infection prevention and control (IPC) regarding mobile phone use among medical students. We demonstrated the presence of organisms on mobile phones of final-year medical students at Makerere University College of Health Sciences and evaluated their awareness of IPC regarding mobile phone hygiene and use in a hospital setting.

METHODS

In this cross-sectional study, organisms from swabs obtained from 79 medical students' mobile phones were identified and antimicrobial susceptibility test carried out using standard biochemical tests and the automated BD Phoenix instrument. Data were collected using a self-administered questionnaire to assess the students' awareness. The analysis was carried out using STATA software version 16.

RESULTS

Seventy (88.6%) mobile phones were contaminated with at least one organism. One hundred forty-eight bacteria were isolated, of which 123 (83.1%) were Gram-positive, 24 (16.2%) were Gram-negative, and 1 (0.7%) was yeast (Candida spp). Coagulase negative staphylococci were the most frequently isolated among Gram-positive bacteria. Acinetobacter baumannii were the most frequently isolated among Gram-negative bacteria. The average IPC practical score regarding mobile phone hygiene (34%) was significantly lower than the average IPC awareness score (77%) (p ≤ 0.0001). Seventy-four (93.7%) students use their phones while rotating in the various wards. Forty (50.6%) of the students cleaned their phones with alcohol-based sanitizer after rotations in the ward. Thirty-five (44.3%) students were aware of IPC programs in the hospital they rotated in.

CONCLUSION

There is a high prevalence of bacterial contamination from mobile phones of medical students. The students had lower IPC practical scores compared to IPC awareness scores regarding mobile phone hygiene irrespective of the ward of rotation. Curriculum of final-year medical students should include IPC-related topics, which incorporate practical skills.

Advantages and Limitations of 16S rRNA Next-Generation Sequencing for Pathogen Identification in the Diagnostic Microbiology Laboratory: Perspectives from a Middle-Income Country

Bacterial culture and biochemical testing (CBtest) have been the cornerstone of pathogen identification in the diagnostic microbiology laboratory. With the advent of Sanger sequencing and later, next-generation sequencing, 16S rRNA next-generation sequencing (16SNGS) has been proposed to be a plausible platform for this purpose. Nevertheless, usage of the 16SNGS platform has both advantages and limitations. In addition, transition from the traditional methods of CBtest to 16SNGS requires procurement of costly equipment, timely and sustainable maintenance of these platforms, specific facility infrastructure and technical expertise. All these factors pose a challenge for middle-income countries, more so for countries in the lower middle-income range. In this review, we describe the basis for CBtest and 16SNGS, and discuss the limitations, challenges, advantages and future potential of using 16SNGS for bacterial pathogen identification in diagnostic microbiology laboratories of middle-income countries.

Antimicrobial Resistance Surveillance in Low- and Middle-Income Countries: Progress and Challenges in Eight South Asian and Southeast Asian Countries

Antimicrobial resistance (AMR) is a serious global health threat and is predicted to cause significant health and economic impacts, particularly in low- and middle-income countries (LMICs). AMR surveillance is critical in LMICs due to high burden of bacterial infections; however, conducting AMR surveillance in resource-limited settings is constrained by poorly functioning health systems, scarce financial resources, and lack of skilled personnel. In 2015, the United Nations World Health Assembly endorsed the World Health Organization's Global Action Plan to tackle AMR; thus, several countries are striving to improve their AMR surveillance capacity, including making significant investments and establishing and expanding surveillance networks. Initial data generated from AMR surveillance networks in LMICs suggest the high prevalence of resistance, but these data exhibit several shortcomings, such as a lack of representativeness, lack of standardized laboratory practices, and underutilization of microbiology services. Despite significant progress, AMR surveillance networks in LMICs face several challenges in expansion and sustainability due to limited financial resources and technical capacity. This review summarizes the existing health infrastructure affecting the establishment of AMR surveillance programs, the burden of bacterial infections demonstrating the need for AMR surveillance, and current progress and challenges in AMR surveillance efforts in eight South and Southeast Asian countries.

Implementation of surgical site infection surveillance in low- and middle-income countries: A position statement for the International Society for Infectious Diseases

Surgical site infection (SSI) rates in low- and middle-income countries (LMICs) range from 8 to 30% of procedures, making them the most frequent healthcare-acquired infection (HAI) with substantial morbidity, mortality, and economic impacts. Presented here is an approach to surgical site infection prevention based on surveillance and focused on five critical areas identified by international experts. These five areas include

1. Collecting valid, high-quality data;

2. Linking HAIs to economic incapacity, underscoring the need to prioritize infection prevention activities;

3. Implementing SSI surveillance within infection prevention and control (IPC) programs to enact structural changes, develop procedural skills, and alter healthcare worker behaviors;

4. Prioritizing IPC training for healthcare workers in LMICs to conduct broad-based surveillance and to develop and implement locally applicable IPC programs; and

5. Developing a highly accurate and objective international system for defining SSIs, which can be translated globally in a straightforward manner.

Finally, we present a clear, unambiguous framework for successful SSI guideline implementation that supports developing sustainable IPC programs in LMICs. This entails

1. Identifying index operations for targeted surveillance;

2. Identifying IPC “champions” and empowering healthcare workers;

3. Using multimodal improvement measures;

4. Positioning hand hygiene programs as the basis for IPC initiatives;

5. Use of telecommunication devices for surveillance and healthcare outcome follow-ups.

Additionally, special considerations for pediatric SSIs, antimicrobial resistance development, and antibiotic stewardship programs are addressed.

Point-prevalence survey of hospital acquired infections in three acute care hospitals in Northern Nigeria

Background

Effective infection prevention and control strategies require reliable data describing the epidemiology of hospital acquired infections (HAIs), and this is currently lacking in Nigeria. The objective of this study was to evaluate the prevalence, types and risk factors associated with HAIs in acute care hospitals in Northern Nigeria.

Methods

A pilot point-prevalence survey was conducted in three acute care hospitals in Northern Nigeria between April and May 2019 using a protocol developed by the European Centre for Disease Prevention and Control. Patients admitted into the wards at or before 8.00 am on the survey date were included. Patients’ medical records were reviewed by a clinical pharmacist with the support of the attending physician and nurse to identify HAIs.

Results

Of the 321 patients surveyed, 50 HAIs were identified among 46 patients translating into a point-prevalence of 14.3%. The most common HAIs were bloodstream infection (38.0%), surgical site infections (32.0%) and pneumonia (12.0%). Neonatal (53.0%), pediatric surgical (26.7%) and surgical (10.1%) specialties had the highest prevalence. Device associated infections represented 16% of all HAIs including bloodstream infections and pneumonia. Of all the HAIs, 15 (30.0%) were present at the time of admission while 75.5% originated from the current hospitals. Univariate analysis showed that newborn (less than 1 month old) (OR: 4.687 95% CI: 1.298–16.927), intubation (OR: 3.966, 95% CI: 1.698–9.261), and neonatal (OR: 41.538 95% CI: 4.980–346.5) and pediatric surgical (OR: 13.091 95% CI: 1.532–111.874) specialties were significantly associated with HAI.

Conclusion

The prevalence of HAI was relatively high compared to other developing countries and was significantly associated with neonatal and pediatric surgical specialties. Hospital infection control strategies should be strengthened to reduce the burden of HAIs.

Antimicrobial resistance in the Pacific Island countries and territories

Antimicrobial resistance (AMR) is a critical global health threat with a disproportionate impact on low-income and middle-income countries (LMICs) due to their higher burden of infections, reduced laboratory surveillance infrastructure and fewer regulations governing antimicrobial use among humans or animals. While there have been increasing descriptions of AMR within many LMICs in WHO's Western Pacific and South East Asian regions, there remains a paucity of data from Pacific Island countries and territories (PICTs). The PICTs represent 22 predominantly middle-income countries and territories with a combined population of 12 million people and 20 official languages, spread over hundreds of separate islands spanning an area corresponding to more than 15% of the earth's surface. Our paper outlines the present state of the evidence regarding AMR in PICTs-discussing the present estimates of AMR and their accompanying limitations, important drivers of AMR, as well as outlining key priorities and potential solutions for tackling AMR in this region. Significant areas for action include developing National Action Plans, strengthening laboratory surveillance systems and educational activities targeted at both healthcare workers and the wider community. Ensuring adequate funding for AMR activities in PICTs is challenging given competing health and environmental priorities, in this context global or regional funding initiatives such as the Fleming Fund can play a key role.

The Global call for action on infection prevention and control

PURPOSE

Healthcare-associated infections (HAIs) constitute a major threat to patient safety and affect hundreds of millions of people worldwide. The World Health Organization in 2016 published guidelines on the core components for infection prevention and control (IPC) programme. This was in response to a global call for focused action. The purpose of this paper is to examine and promote understanding of the tenets of the IPC guidelines and highlight their implications for implementation in low-income countries.

DESIGN/METHODOLOGY/APPROACH

Drawing from personal experiences in leading the implementation of health programmes as well as a review of published and grey literature on IPC, authors discussed and proposed practical approaches to implement IPC priorities in low-income setting.

FINDINGS

Availability of locally generated evidence is paramount to guide strengthening leadership and institutionalisation of IPC programmes. Preventing infections is everybody's responsibility and should be viewed as such and accorded the required attention.

ORIGINALITY/VALUE

Drawing from recent experiences from disease outbreaks and given the heavy burden of HAIs especially in low-income settings, this paper highlights practical approaches to guide implementation of the major components of IPC.

Addressing Hand Hygiene Compliance in a Low-Resource Neonatal Intensive Care Unit: a Quality Improvement Project

OBJECTIVE

Our goal for this study was to quantify healthcare provider compliance with hand hygiene protocols and develop a conceptual framework for increasing hand hygiene compliance in a low-resource neonatal intensive care unit.

MATERIALS AND METHODS

We developed a 3-phase intervention that involved departmental discussion, audit, and follow-up action. A 4-month unobtrusive audit during night and day shifts was performed. The audit results were presented, and a conceptual framework of barriers to and solutions for increasing hand hygiene compliance was developed collectively.

RESULTS

A total of 1308 hand hygiene opportunities were observed. Among 1227 planned patient contacts, hand-washing events (707 [58.6%]), hand rub events (442 [36%]), and missed hand hygiene (78 [6.4%]) events were observed. The missed hand hygiene rate was 20% during resuscitation. Missed hand hygiene opportunities occurred 3.2 times (95% confidence interval, 1.9-5.3 times) more often during resuscitation procedures than during planned contact and 6.14 times (95% confidence interval, 2.36-16.01 times) more often when providers moved between patients. Structural and process determinants of hand hygiene noncompliance were identified through a root-cause analysis in which all members of the neonatal intensive care unit team participated. The mean hand-washing duration was 40 seconds. In 83% of cases, drying hands after washing was neglected. Hand recontamination after hand-washing was seen in 77% of the cases. Washing up to elbow level was observed in 27% of hand-wash events. After departmental review of the study results, hand rubs were placed at each bassinet to address these missed opportunities.

CONCLUSIONS

Hand hygiene was suboptimal during resuscitation procedures and between patient contacts. We developed a conceptual framework for improving hand hygiene through a root-cause analysis.

Participatory approach to quality development in infection prevention and control (IPC) in Nigerian health facilities

The development of an educational concept of a training programme for infection prevention and control (IPC) was seen as a key issue to successfully address the complexity of change processes of professional IPC routines in clinical procedures. Therefore, the Nigeria Centre for Disease Control (NCDC), Nigeria, and the Robert Koch Institute (RKI), Germany established an interdisciplinary project framework, involving knowledge and competences from different disciplines and professions like health professionals, epidemiologists and educators (MAURICE project). A multi-module training programme for health care workers to improve IPC standards was developed and implemented based on the participatory approach and a systemic view for organizational change.

Global infection prevention gaps, needs, and utilization of educational resources: A cross-sectional assessment by the International Society for Infectious Diseases

OBJECTIVE

The Guide to Infection Control in the Hospital (Guide) is an open access resource produced by the International Society for Infectious Diseases (ISID) to assist in the prevention of infection acquisition and transmission worldwide. A survey was distributed to 8055 current Guide users to understand their needs.

METHODS

The survey consisted of 48-questions regarding infection prevention and control (IPC) availability and needs. Dichotomous questions, Likert scale-type questions, and open-and closed-ended questions were used.

RESULTS

Respondents (n=1121) from 194 countries and six WHO regions participated in the survey. 43% (488) identified as physicians. Personal protective equipment (PPE) availability, training, and antimicrobial susceptibility testing varied between regions. Only 11% of respondents from low-income countries reported consistent access to respiratory equipment, 12% to isolation gowns, 4% to negative pressure rooms or personnel trained in IPC, and 20% to antimicrobial resistance testing. This differed significantly to high and upper middle-income resource settings (p<0.05). 80% of all respondents used smartphones or tablets at the workplace.

CONCLUSIONS

This survey demonstrates varied access to IPC equipment and training between high and low-income settings worldwide. Our results demonstrated many respondents across all regions utilize mobile technology, providing opportunities for rapid distribution of resource specific, up-to-date IPC content.

Compliance of Nurses and Hospitals With Ventilator-Associated Pneumonia Prevention Guidelines: A Middle Eastern Survey

This study was a self-reported cross-sectional survey that investigated nurses' and hospitals' compliance with ventilator-associated pneumonia prevention guidelines and the barriers and factors that affect their level of compliance. A questionnaire was completed by 471 intensive care unit nurses from 16 medical centers in 3 Middle Eastern countries: Jordan, Egypt, and Saudi Arabia. The results show that both nurses and hospitals have insufficient compliance. Previous education, experience, and academic degree were all found to affect nurses' compliance.

Vertical transmission of positive-sense single-stranded RNA viruses in plants as a model for arboviral induced teratogenesis

Teratogenic viruses have increased public health importance with the emergence of Zika virus and a recent decline in rubella virus vaccination. Of the seven viruses known to cause birth defects in humans, three are mosquito-borne pathogens. Ethical oversight, compliance, rising costs, and the need for specialized training slow the pace of study of these human pathogens compared to study of similar teratogenic viruses in plants. Plant viruses have served as models for human viruses which can be applied to animal systems. This review describes the similar features of plant and animal teratogenic arboviruses and the common systems and barriers that are encountered during vertical transmission in the host.
