School-aged children are vulnerable to infectious diseases due to their developing immune systems and frequent social interactions. The COVID-19 pandemic underscored the importance of non-pharmaceutical interventions, like hand hygiene (HH). This study evaluated the changes achieved through a school-based intervention to Guatemalan primary school students’ HH knowledge, attitudes, and self-reported practices while collecting teacher feedback to inform future efforts. The intervention included handwashing festivals, environmental nudges, and the regular delivery of soap and alcohol-based hand rub (ABHR). Knowledge, attitudes, and practices (KAP) surveys were conducted pre- and post-intervention with 109 and 144 students, respectively. Six teachers participated in interviews to provide perspectives. Significant improvements were observed in students’ knowledge of HH’s role in preventing disease (pre: 84.4%; post: 96.5; p < 0.01) and recognition of critical moments (pre: 84.4%; post: 92.4%; p < 0.05). Self-reported practices also improved, with more students reporting washing their hands for 20 s or more (pre: 68.8%; post: 79.9%; p < 0.05). Fewer students reported liking ABHR after the intervention (pre: 89%; post: 78.5%; p < 0.05). Teachers reported increased HH practices and provided feedback to enhance interventions. These findings highlight the effectiveness of school-based interventions and emphasize the importance of addressing knowledge gaps and incorporating teacher insights for sustained public health benefits.

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 primaryand secondary-level 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, followup) 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 the 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 multi-modal 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 (WASH) services in schools are essential to reduce infectious disease transmission, including that of COVID-19. This study aimed to establish a baseline of WASH services in six public elementary schools in Guatemala, with a focus on hand hygiene. We used the WHO/UNICEF Joint Monitoring Programme (JMP) report indicators to assess the WASH infrastructure at each school. We collected water samples from easily accessible water points (pilas, or bathroom sinks) at each school to test for the presence of total coliforms and E. coli. In-depth interviews were carried out with teachers to understand hand hygiene practices and systems at school. Results indicate that all schools had water available at the time of the survey. All water samples at four schools tested positive for total coliforms and at one school, positive for E. coli. All schools had sanitation facilities, but services were limited. Only 43% of handwashing stations at schools had soap available. No school had disability-inclusive WASH services. Financial constraints and a lack of appropriate WASH infrastructure were the main barriers reported by teachers to meet hand hygiene needs at school. Appropriate access to WASH infrastructure and supplies could increase hand hygiene practices and improve learning conditions for students.

Access to safe drinking water remains a major public health challenge in low- and middle-income countries (LMICs), with 4.4 billion people lacking safely managed sources. Contaminated water contributes to infectious diseases and antimicrobial resistance, increasing morbidity and mortality. While interventions guided by the WHO/UNICEF Joint Monitoring Programme (JMP) aim to improve water access, sociocultural factors influencing water use are likely to play a critical role in developing effective interventions. To assess how sociocultural factors can inform water safety interventions, this study combines cultural consensus analysis of drinking water quality with microbiological assessments of water quality in 30 urban and 30 rural households in Quetzaltenango. Water samples were tested for coliforms, Escherichia coli, and antimicrobial-resistant Enterobacterales. Participants ranked bottled water as the safest source, yet laboratory analysis revealed bottled water had the highest coliform contamination (83.3%). Piped household water, another highly ranked source, exhibited high E. coli contamination (27.8%), presence of extended-spectrum beta-lactamase (ESBL) Enterobacterales (11.1%), and presence of carbapenem-resistant Enterobacterales (11.1%). While JMP guidelines are essential for water safety assessments, sociocultural perceptions play a crucial role in shaping water consumption behaviors. Integrating ethnographic methods with water quality assessments can lead to the design of more nuanced water safety interventions.

Hand hygiene (HH) is essential for preventing disease transmission, particularly in schools where children are in close contact with other children. This study evaluated a school-based intervention on observed HH practices and hand cleanliness in six primary schools in Guatemala. Hand cleanliness was measured using the Quantitative Personal Hygiene Assessment Tool. The intervention included (1) HH behavior change promotion through Handwashing Festivals, and (2) increased access to HH materials at HH stations. Handwashing Festivals were day-long events featuring creative student presentations on HH topics. Schools were provided with soap and alcohol-based hand rub throughout the project to support HH practices. Appropriate HH practices declined from 51.2% pre-intervention to 33.1% post-intervention, despite an improvement in median Quantitative Personal Hygiene Assessment Tool scores from 6 to 8, indicating cleaner hands. Logistic regression showed higher odds of proper HH when an assistant was present. The decline in HH adherence was likely influenced by fewer assistants and changes in COVID-19 policies, while improvements in hand cleanliness may reflect observational bias. These findings emphasize the importance of sustained behavior change strategies, reliable HH material access, and targeted interventions to address gaps in HH practices, guiding school health policy and resource allocation.

Objective. Patient safety is challenging for health systems around the world, particularly in low- and middle-income countries such as Guatemala. The goal of this report is to summarize a strategic planning process for a national patient safety plan in Guatemala. Methods. This strategic planning process involved multiple stakeholders, including representatives of the Guatemala Ministry of Health and Social Assistance, medical leadership from across the public health system, and academic experts from Guatemala and the United States of America. We used mixed methods (quantitative and qualitative surveys) and a nominal group technique at a national symposium to prioritize patient safety challenges across Guatemala, and subsequent meetings to develop a national patient safety plan. Results. This national patient safety plan outlines four domains to advance patient safety across the public hospital system over a five-year period in Guatemala: leadership and governance, training and awareness, safety culture, and outcome metrics. For each domain, we developed a set of goals, activities, outputs, and benchmarks to be overseen by the Ministry of Health. Conclusions. With this national patient safety plan, Guatemala has made a long-term commitment to improving patient safety across the public hospital system of Guatemala. Future efforts will require its extension to all levels of the Guatemalan health system.
