Factors Associated with Hand Hygiene Adherence Among Healthcare Workers in Guatemala during the COVID-19 Pandemic

BACKGROUND

Healthcare-associated infections are prevalent in low- and middle-income countries and may be reduced through proper hand hygiene (HH) adherence during patient care.

AIM

We produced and distributed alcohol-based hand rub (ABHR) to 19 public primary and secondary-level public healthcare facilities in Quetzaltenango, Guatemala, and carried out HH observations to assess healthcare workers' (HCWs) HH adherence, and to identify factors associated with this practice. HH adherence was defined as washing hands with soap and water or using ABHR.

METHODS

Observations were conducted before (2021, baseline) and after (2022, follow-up) ABHR distribution to evaluate the evolution of HH practices over time. Bivariate comparisons and mixed-effects logistic regression models were used to explore associations between HH adherence and the following independent variables: healthcare facility level, type of contact performed, timing of HH performance, occupational category of HCW and materials present (e.g. water, soap, ABHR) FINDINGS: We observed 243 and 300 patient interactions among 67 and 82 HCWs at each time point respectively. HH adherence was low for both observation periods (40% at baseline and 35% at follow-up). HCWs were more likely to adhere to HH during invasive contacts, after patient contact, and if HCW was a physician.

CONCLUSION

HH adherence varied by scenario, which underscores the importance of addressing multiple determinants of behaviour change to improve adherence. This requires interventions implemented with a multimodal approach that includes both increasing access to HH materials and infrastructure, as well as HH education and training, monitoring and feedback, reminders, and promoting a HH safety culture.

Water, sanitation and hygiene at sex work venues to support menstrual needs

Introduction

Adequate menstrual health and hygiene (MHH) is necessary for women's health and equity of all menstruators. Female sex workers (FSW) require good MHH to prevent discomfort and exposure to pathogens. No studies have evaluated water, sanitation, and hygiene (WASH) conditions of FSW. We report on a cross-sectional WASH assessment at FSW venues in Kisumu, western Kenya.

Methods

Stakeholders identified 77 FSW venues in Kisumu, of which 47 were randomly sampled and visited between April-May 2023. A standardized structured survey of WASH conditions was deployed by trained research staff using Android tablets after proprietor's consent. WASH scores ranging 0-3 were computed based on point each for direct observation of water available, soap available, and acceptable latrine. MHH scores ranging between 0-4 were computed (one point each) for direct observation of: currently available soap and water, locking door on a usable latrine, functional lighting, and a private area for changing clothes or menstrual materials, separate from the latrine(s). WASH and MHH scores were compared by venue type using non-parametric Kruskal-Wallis tests, and non-parametric Spearman rank tests.

Results

Full WASH criteria was met by 29.8% of venues; 34.0% had no adequate WASH facilities; 46.8% had no female latrine; and 25.5% provided soap and water in private spaces for women. While 76.6% had menstrual waste disposal only 14 (29.8%) had covered bins. One in 10 venues provided adequate MHM facilities. Poorest WASH facilities were in brothels and in bars, and three-quarters of bars with accommodation had no MHH facilities.

Discussion

WASH and MHH services were sub-optimal in the majority of FSW venues, preventing menstrual management safely, effectively, with dignity and privacy. This study highlights the unmet need for MHH support for this population. Poor MHH can deleteriously impact FSW health and wellbeing and compound the stigma and shame associated with their work and ability to stay clean. Acceptable and cost-effective solutions to sustainably improve WASH facilities for these populations are needed.

Migrants' living conditions, perceived health needs and implications for the use of antibiotics and antimicrobial resistance in the United Kingdom: A qualitative study

Background and Aims

Antimicrobial resistance (AMR) is among the top public health concerns around the globe. Migrants, especially forced migrants, could be at higher risk of acquiring and transmitting AMR during their journeys or in host countries. There is limited understanding regarding migrants' living conditions and the wider factors contributing to their risk of acquiring infections, and behaviors around antimicrobial use, and AMR development. In this study, we aimed to explore transit experiences, living conditions, and antibiotic use of migrants living in the United Kingdom.

Methods

We conducted semistructured qualitative interviews with 27 participants and identified five themes regarding migrants' journey and their living conditions during transit and after arriving in the United Kingdom, their access to water, sanitation and hygiene (WASH), and their use of antibiotics.

Results

Migrants, particularly forced migrants, experienced unfavorable living conditions, poor access to WASH, and challenges in accessing healthcare, which further contributed to health conditions like urinary and skin problems. Isolation and difficulty in accessing healthcare played significant roles in migrants' perceived need for storing and using antibiotics as a safety net.

Conclusion

The findings highlight the need for coordinated and multilevel interventions to address these challenges and contribute toward tackling AMR and improving the health of this population group.

Antimicrobial Resistance and Environmental Health: A Water Stewardship Framework for Global and National Action

Antimicrobial resistance (AMR) is a global health crisis that affects all life on Earth. In 2015, the World Health Organization developed guidance to combat AMR in accordance with a One Health framework considering human, animal, and environment sectors of planetary health. This study reviewed global guidance and 25 National Action Plans to evaluate thematic priorities in One Health AMR approaches using a novel framework that additionally facilitated the identification of water-related stewardship gaps, as water resources are recognized as the primary environmental AMR reservoir and dissemination pathway. This review found that global and national stewardship primarily focuses on mitigating antibiotic use in the human and animal sectors, overlooking environmental drivers, particularly diverse environmental waters. The findings of this study highlight the need to broaden the scope of water-related AMR concerns beyond water, sanitation, and hygiene (WASH) infrastructure for water supply and wastewater treatment, and account for environmental waters in AMR development and dissemination, particularly in low-income countries where half a billion people rely on environmental waters to meet daily needs. Equitably accounting for water environments, supplies, and waste in AMR prevention, mitigation, surveillance, and innovation can significantly enhance the integration of environmental objectives in One Health AMR stewardship.

Characteristics of persistent hotspots of Schistosoma mansoni in western Côte d'Ivoire

BACKGROUND

Preventive chemotherapy with praziquantel is the cornerstone of schistosomiasis control. However, in some social-ecological settings, the prevalence and/or intensity of Schistosoma infection does not lower meaningfully despite multiple rounds of preventive chemotherapy, a phenomenon termed persistent hotspot (PHS). We assessed the characteristics of PHS in a Schistosoma mansoni-endemic area of Côte d'Ivoire.

METHODS

In October 2016, a cross-sectional survey was conducted in 14 schools in the western part of Côte d'Ivoire, one year after multiple rounds of preventive chemotherapy. In each school, 50 children aged 9-12 years provided two stool samples and one urine sample. Stool samples were subjected to triplicate Kato-Katz thick smears for S. mansoni diagnosis. Urine samples were examined by a filtration method for S. haematobium eggs. PHS was defined as failure to achieve a reduction in the prevalence of S. mansoni infection of at least 35% and/or a reduction of infection intensity of at least 50%. Six schools underwent more detailed investigations, including a questionnaire survey for demographic characteristics and a malacological survey.

RESULTS

In the six schools subjected to detailed investigations, the overall prevalence of S. mansoni and S. haematobium was 9.5% and 2.6%, respectively. Four schools were classified as PHS. The S. mansoni prevalence in the four PHS was 10.9% compared to 6.6% in the remaining two schools. The S. mansoni infection intensity, expressed as arithmetic mean eggs per gram of stool (EPG) among infected children, was 123.8 EPG in PHS and 18.7 EPG in the other two schools. Children bathing in open freshwater bodies were at higher odds of S. mansoni infection (odds ratio: 4.5, 95% confidence interval: 1.6-12.6). A total of 76 human-water contact sites (53 in PHS and 23 in the other schools) were examined and 688 snails were collected, including potential intermediate host snails of Schistosoma (Biomphalaria pfeifferi, Bulinus forskalii, Bu. globosus and Bu. truncatus).

CONCLUSION

Children in PHS schools bathed more frequently in open freshwater bodies, and hence, they are more exposed to Schistosoma transmission. Our findings call for an integrated control approach, complementing preventive chemotherapy with other interventions, particularly in PHS settings.

Impact of the "BALatrine" Intervention on Soil-Transmitted Helminth Infections in Central Java, Indonesia: A Pilot Study

Many latrine campaigns in developing countries fail to be sustained because the introduced latrine is not appropriate to local socio-economic, cultural and environmental conditions, and there is an inadequate community health education component. We tested a low-cost, locally designed and constructed all-weather latrine (the “BALatrine”), together with community education promoting appropriate hygiene-related behaviour, to determine whether this integrated intervention effectively controlled soil-transmitted helminth (STH) infections. We undertook a pilot intervention study in two villages in Central Java, Indonesia. The villages were randomly allocated to either control or intervention with the intervention village receiving the BALatrine program and the control village receiving no program. STH-infection status was measured using the faecal flotation diagnostic method, before and eight months after the intervention. Over 8 months, the cumulative incidence of STH infection was significantly lower in the intervention village than in the control village: 13.4% vs. 27.5% (67/244 vs. 38/283, p < 0.001). The intervention was particularly effective among children: cumulative incidence 3.8% (2/53) for the intervention vs. 24.1% (13/54) for the control village (p < 0.001). The integrated BALatrine intervention was associated with a reduced incidence of STH infection. Following on from this pilot study, a large cluster-randomised controlled trial was commenced (ACTRN12613000523707).

Biosocial Determinants of Persistent Schistosomiasis among Schoolchildren in Tanzania despite Repeated Treatment

Schistosomiasis is a parasitic disease endemic to Tanzania and other countries of the global south, which is currently being addressed through preventive chemotherapy campaigns. However, there is growing recognition that chemotherapy strategies will need to be supplemented to sustainably control and eventually eliminate the disease. There remains a need to understand the factors contributing to continued transmission in order to ensure the effective configuration and implementation of supplemented programs. We conducted a cross-sectional questionnaire, to evaluate the biosocial determinants facilitating the persistence of schistosomiasis, among 1704 Tanzanian schoolchildren residing in two districts undergoing a preventive chemotherapeutic program: Rufiji and Mkuranga. A meta-analysis was carried out to select the diagnostic questions that provided a likelihood for predicting infection status. We found that self-reported schistosomiasis continues to persist among the schoolchildren, despite multiple rounds of drug administration.Using mixed effects logistic regression modeling, we found biosocial factors, including gender, socio-economic status, and water, sanitation, and hygiene (WASH)-related variables, were associated with this continued schistosomiasis presence. These findings highlight the significant role that social factors may play in the persistence of disease transmission despite multiple treatments, and support the need not only for including integrated technical measures, such as WASH, but also addressing issues of poverty and gender when designing effective and sustainable schistosomiasis control programs.
