RESUMEN
Taking leftover prescribed antibiotics without consulting a healthcare professional is problematic for the efficacy, safety, and antibiotic stewardship. We conducted a cross-sectional survey of adult patients in English and Spanish between January 2020 and June 2021 in six safety-net primary care clinics and two private emergency departments. We assessed the reasons for stopping prescribed antibiotics early and what was done with the leftover antibiotics. Additionally, we determined 1) prior leftover antibiotic use, 2) intention for future use of leftover antibiotics, and 3) sociodemographic factors. Of 564 survey respondents (median age of 51), 45% (251/564) reported a history of stopping antibiotics early, with 171/409 (42%) from safety net and 80/155 (52%) from the private clinics. The most common reason for stopping prescribed antibiotics early was "because you felt better" (194/251, 77%). Among survey participants, prior use of leftover antibiotics was reported by 149/564 (26%) and intention for future use of leftover antibiotics was reported by 284/564 (51%). In addition, higher education was associated with a higher likelihood of prior leftover use. Intention for future use of leftover antibiotics was more likely for those with transportation or language barriers to medical care and less likely for respondents with private insurance. Stopping prescribed antibiotics early was mostly ascribed to feeling better, and saving remaining antibiotics for future use was commonly reported. To curb nonprescription antibiotic use, all facets of the leftover antibiotic use continuum, from overprescribing to hoarding, need to be addressed.

BACKGROUND: Using antibiotics without a prescription is potentially unsafe and may increase the risk of antimicrobial resistance. We evaluated the effect of patient, health system, and clinical encounter factors on intention to use antibiotics without a prescription that were (1) purchased in the United States, (2) obtained from friends or relatives, (3) purchased abroad, or (4) from any of these sources. METHODS: The survey was performed January 2020-June 2021 in 6 publicly funded primary care clinics and 2 private emergency departments in Texas, United States. Participants included adult patients visiting 1 of the clinical settings. Nonprescription use was defined as use of antibiotics without a prescription; intended use was professed intention for future nonprescription antibiotic use. RESULTS: Of 564 survey respondents (33% Black and 47% Hispanic or Latino), 246 (43.6%) reported prior use of antibiotics without a prescription, and 177 (31.4%) reported intent to use antibiotics without a prescription. If feeling sick, respondents endorsed that they would take antibiotics obtained from friends/relatives (22.3% of 564), purchased in the United States without a prescription (19.1%), or purchased abroad without a prescription (17.9%). Younger age, lack of health insurance, and a perceived high cost of doctor visits were predictors of intended use of nonprescription antibiotics from any of the sources. Other predictors of intended use were lack of transportation for medical appointments, language barrier to medical care, Hispanic or Latino ethnicity, and being interviewed in Spanish. CONCLUSIONS: Patients without health insurance who report a financial barrier to care are likely to pursue more dangerous nonprescription antimicrobials. This is a harm of the US fragmented, expensive healthcare system that may drive increasing antimicrobial resistance and patient harm.

Non-prescription antibiotic use (using antibiotics without clinical guidance) increases the risk of the development of antibiotic resistance, adverse drug reactions, and other potential patient harm. Few studies have explored non-prescription use in children in the U.S. From January 2021 to April 2022, a diverse sample of caregivers of children under 18 years were surveyed in English and Spanish at two safety net clinics in Texas. We assessed the prevalence of antibiotic use in children in the previous 12 months, storage of antimicrobials, and intended use of non-prescription antibiotics (professed intention for future non-prescription antibiotic use). We also measured sociodemographic factors, types of antibiotics used, and symptoms that trigger non-prescription use. The response rate was 82%, and 17% were surveyed in Spanish. Of 322 participants surveyed, three Spanish-speaking caregivers reported giving non-prescription antibiotics to their child in the previous 12 months. Approximately 21% (n = 69) reported storing antimicrobials at home, specifically amoxicillin (n = 52), clindamycin (n = 10), cephalexin (n = 5), penicillin (n = 3), and trimethoprim/sulfamethoxazole (n = 3). Nearly 15% (n = 46) reported intention to give non-prescription antibiotics to their children. Younger caregiver age was associated with storage and intended use of non-prescription antibiotics. Our findings will guide the development of an educational intervention to decrease non-prescription antibiotic use.
RESUMEN
BACKGROUND: Non-prescription antibiotic use includes taking an antibiotic without medical guidance (e.g., leftovers, from friends/relatives, or purchased without a prescription). Non-prescription use contributes to antimicrobial resistance, adverse drug reactions, interactions, superinfection, and microbiome imbalance. Qualitative studies exploring perspectives regarding non-prescription use among Hispanic patients are lacking. We used the Kilbourne Framework for Advancing Health Disparities Research to identify factors influencing patients' non-prescription use and organize our findings. METHODS: Our study includes Hispanic primary care clinic patients with different types of health insurance coverage in the Houston metroplex who endorsed non-prescription use in a previous survey. Semistructured interviews explored the factors promoting non-prescription use in Hispanic adults. Interviews were conducted remotely, in English or Spanish, between May 2020 and October 2021. Inductive coding and thematic analysis identified motives for non-prescription use. RESULTS: Participants (n = 35) were primarily female (68.6%) and aged 27 to 66. Participants reported obtaining antibiotics through trusted persons, sold under-the-counter in US markets, and purchased without a prescription abroad. Factors contributing to non-prescription use included beliefs that the doctor visit was unnecessary, limited access to healthcare (due to insurance constraints, costs, and clinic wait times), and communication difficulties (e.g., language barriers with clinicians and perceived staff rudeness). Participants expressed confidence in medical recommendations from pharmacists and trusted community members. CONCLUSIONS: Patient, healthcare system, and clinical encounter factors contribute to non-prescription use in Hispanic communities. Antibiotic stewardship interventions that involve pharmacists and trusted persons, improve access to care, and address communication barriers and cultural competency in the clinic may help reduce non-prescription use in these communities.

Using antibiotics without medical guidance (non-prescription antibiotic use) may contribute to antimicrobial resistance. Hispanic individuals are a growing demographic group in the United States (US) with a high prevalence of non-prescription antibiotic use. We investigated the effects of acculturation and subjective norms on Hispanic individuals' intentions to use antibiotics without a prescription from the following sources: (1) markets in the United States (not legal), (2) other countries (abroad), (3) leftovers from previous prescriptions, and (4) friends/relatives. We surveyed self-identified Hispanic outpatients in eight clinics from January 2020 to June 2021 using the previously validated Short Acculturation Scale for Hispanics (SASH). Of the 263 patients surveyed, 47% reported previous non-prescription use, and 54% expressed intention to use non-prescription antibiotics if feeling sick. Individuals with lower acculturation (Spanish-speaking preferences) expressed greater intentions to use antibiotics from abroad and from any source. Individuals with more friends/relatives who obtain antibiotics abroad were over 2.5 times more likely to intend to use non-prescription antibiotics from friends/relatives (p = 0.034). Other predictors of intention to use non-prescription antibiotics included high costs of doctor visits and perceived language barriers in the clinic. Antibiotic stewardship interventions in Hispanic communities in the United States should consider the sociocultural and healthcare barriers influencing non-prescription use and promote language-concordant healthcare.
RESUMEN
Few studies have harnessed social media to explore patients' experiences with urinary tract infection (UTI); therefore, we captured UTI experiences and future research suggestions through a Twitter-disseminated survey. The survey posed three qualitative questions inquiring about the impact of UTIs, greatest UTI management hurdle, and research suggestions. We also asked participants to rate how seriously others perceive UTIs and the importance of UTIs in their life (scale: 1-100 (highest)). The study period spanned from January to June 2021. Coding was performed in duplicate, followed by thematic analysis. Of 466 participants from 22 countries, 128 considered their UTIs recurrent (n = 43) or chronic (n = 85). Six major themes emerged: UTIs drastically impact (1) physical and (2) mental health and (3) cause severe limitations in life activities. Patients reported (4) negative clinician interactions and perceived inadequate care, (5) a lack of knowledge and awareness surrounding UTIs, and (6) research gaps in UTI diagnostics and treatment. The participants considered UTIs extremely important (median: 100, IQR: 90-100), but characterized others' perceptions of them as less serious (median: 20, IQR: 10-30). Our survey revealed a patient population struggling with UTIs, particularly chronic UTIs. Our findings highlight perceived shortcomings in current UTI treatment and diagnostics.

RESUMEN
BACKGROUND: Diarrhoea, a global cause of child mortality and morbidity, is linked to adverse consequences including childhood stunting and death from other diseases. Few studies explore how diarrhoeal mortality varies subnationally, especially by cause, which is important for targeting investments. Even fewer examine indirect effects of diarrhoeal morbidity on child mortality. We estimated the subnational distribution of mortality, morbidity, and childhood stunting attributable to enterotoxigenic Escherichia coli (ETEC) and shigella infection in children younger than 5 years from 11 eastern and central African countries. These pathogens are leading causes of diarrhoea in young children and have been linked to increased childhood stunting. METHODS: We combined proxy indicators of morbidity and mortality risk from the most recent Demographic and Health Surveys with published relative risks to estimate the potential distribution of diarrhoeal disease risk. To estimate subnational burden, we used country-specific or WHO region-specific morbidity and mortality estimates and distributed them subnationally by three indices that integrate relevant individual characteristics (ie, underweight, probability of receiving oral rehydration treatment of diarrhoea, and receiving vitamin A supplementation) and household characteristics (ie, type of drinking water and sanitation facilities). FINDINGS: Characterising ETEC and shigella subnational estimates of indirect morbidity (infection-attributable stunting) and indirect mortality (stunting-related deaths from other infectious diseases) identified high-risk areas that could be missed by traditional metrics. Burundi and Democratic Republic of the Congo had the highest ETEC-associated and shigella-associated mortality and stunting rates. Mozambique, Democratic Republic of the Congo, and Zimbabwe had the greatest subnational heterogeneity in most ETEC and shigella mortality measures. Inclusion of indirect ETEC and shigella mortality in burden estimates resulted in a 20-30% increase in total ETEC and shigella mortality rates in some subnational areas. INTERPRETATION: Understanding the indirect mortality and morbidity of diarrhoeal pathogens on a subnational level will strengthen disease control strategies and could have important implications for the relative impact and cost-effectiveness of new enteric vaccines. Because our methods rely on publicly available data, they could be employed for national planning. FUNDING: Bill & Melinda Gates Foundation.

BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) and shigella are two major pathogens that cause moderate-to-severe diarrhoea in children younger than 5 years. Diarrhoea is associated with an increased risk of stunting, which puts children at risk of death due to other infectious diseases. METHODS: We modelled ETEC-related and shigella-related mortality and the effect of moderate-to-severe diarrhoea episodes to determine the number of children with stunting due to these infections in 79 low-income and lower middle-income countries. We applied population attributable risk for increased number of deaths due to other infectious diseases in children who are stunted. We calculated 95% uncertainty intervals (UIs) for the point estimates. FINDINGS: In children younger than 5 years, we estimate 196 million (95% UI 135-269) episodes of ETEC and shigella diarrhoea occur annually, resulting in 3·5 million (0·8-5·4) cases of moderate-to-severe stunting and 44â400 (29â400-59â800) total ETEC deaths and 63â100 (44â000-81â900) total shigella deaths in 2015. Additional infectious disease mortality due to stunting resulted in increases of 24% (8-34; for ETEC) and 28% (10-39; for shigella) over direct deaths due to diarrhoeal episodes. The distribution of mortality and morbidity varied geographically, with African Region and Eastern Mediterranean Region countries bearing the greatest burden. INTERPRETATION: The expanded effects of non-fatal ETEC and shigella-related diarrhoeal episodes can have lasting consequences. Prevention of these infections could reduce the risk of direct death and stunting and deaths due to other infectious diseases. Understanding the countries and populations with the highest disease risk helps to target interventions for the most vulnerable populations. FUNDING: The Bill & Melinda Gates Foundation.

While diarrhea mortality in children has declined over the last two decades, there has been a slower decline in diarrheal episodes. Repeated diarrheal episodes are associated with childhood stunting, which leads to increased mortality risk from infectious diseases. Vaccine candidates are under development for enterotoxigenic Escherichia coli [ETEC] and Shigella, important enteric pathogens in children in low income countries. These future vaccines could significantly reduce diarrheal burden, prevent ETEC- and Shigella-induced stunting, and stunting-associated mortality. We developed a cost-effectiveness model for two putative standalone ETEC and Shigella vaccine candidates to evaluate vaccine impact on mortality, morbidity, stunting, and stunting-associated deaths from other infectious diseases. We modeled impact over the first ten years after vaccine introduction in children under five years old living in 79 low and low-middle income countries. ETEC and Shigella diarrhea would cause an estimated 239,300 [95% UL: 179,700-309,800] and 340,300 [256,500-440,800] child deaths, respectively, from years 2025 to 2034. Most of these deaths would occur in AFRO countries. ETEC and Shigella moderate-to-severe diarrheal episodes would result in over 13.7 [8.4-19.0] and 21.4 [13.1-29.8] million stunted children, respectively. Introducing ETEC or Shigella vaccine each with 60% efficacy could prevent 92,000 [61,000-129,000] ETEC and 126,600 [84,000-179,000] Shigella direct deaths and 21,400 [11,300-34,800] ETEC- and 34,200 [18,000-56,000] Shigella-induced stunting deaths. ETEC ICERs ranged from $2172/DALY [1457-4369] in AFRO to $19,172/DALY [12,665-39,503] in EURO. Shigella ICERs ranged from $952/DALY [632-2001] in EMRO to $640,316/DALY [434,311-1,297,192] in EURO. Limitations of this analysis include uncertainty of vaccine efficacy, duration of protection, and vaccine price. Inclusion of other infectious disease mortality due to stunting provides a more accurate assessment of total ETEC and Shigella disease burden and increased the projected impact and cost-effectiveness of vaccination. Introducing vaccines only in high burden countries and regions could substantially reduce cost without substantially reducing impact.
RESUMEN
Globally, rotavirus is a leading cause of childhood diarrhea and related mortality. Although rotavirus vaccination has been introduced in many countries worldwide, there are numerous low- to middle-income countries that have not yet introduced. Pakistan is one of the countries with the highest number of rotavirus deaths in children under five years. Although rotavirus infection is almost universal among children, mortality is often a result of poor nutrition and lack of access to health care and other aspects of poverty. We assess the impact and cost-effectiveness of introducing childhood rotavirus vaccination in Pakistan. We use household data from the 2012-2013 Demographic Health survey in Pakistan to estimate heterogeneity in rotavirus mortality risk, vaccination benefits, and cost-effectiveness across geographic and economic groups. We estimate two-dose rotavirus vaccination coverage that would be distributed through a routine vaccination program. In addition, we estimate rotavirus mortality (burden), and other measures of vaccine cost-effectiveness and impact by subpopulations of children aggregated by region and economic status. Results indicate that the highest estimated regional rotavirus burden is in Sindh (3.3 rotavirus deaths/1000 births) and Balochistan (3.1 rotavirus deaths/1000 births), which also have the lowest estimated vaccination coverage, particularly for children living in the poorest households. In Pakistan, introduction could prevent 3061 deaths per year with current routine immunization patterns at an estimated $279/DALY averted. Increases in coverage to match the region with highest coverage (Islamabad) could prevent an additional 1648 deaths per year. Vaccination of children in the highest risk regions could result in a fourfold mortality reduction as compared to low risk children, and children in the poorest households have a three to four times greater mortality reduction benefit than the richest. Based on the analysis presented here, the benefits and cost-effectiveness of rotavirus vaccination can be maximized by reaching economically and geographically vulnerable children.

Malaria is an important health burden in Zambia with proper diagnosis remaining as one of the biggest challenges. The need for reliable diagnostics is being addressed through the introduction of rapid diagnostic tests (RDTs). However, without sufficient laboratory amenities in many parts of the country, diagnosis often still relies on non-specific, clinical symptoms. In this study, geographical information systems were used to both visualize and analyze the spatial distribution and the risk factors related to the diagnosis of malaria. The monthly reported, district-level number of malaria cases from January 2009 to December 2014 were collected from the National Malaria Control Center (NMCC). Spatial statistics were used to reveal cluster tendencies that were subsequently linked to possible risk factors, using a non-spatial regression model. Significant, spatio-temporal clusters of malaria were spotted while the introduction of RDTs made the number of clinically diagnosed malaria cases decrease by 33% from 2009 to 2014. The limited access to road network(s) was found to be associated with higher levels of malaria, which can be traced by the expansion of health promotion interventions by the NMCC, indicating enhanced diagnostic capability. The capacity of health facilities has been strengthened with the increased availability of proper diagnostic tools and through retraining of community health workers. To further enhance spatial decision support systems, a multifaceted approach is required to ensure mobilization and availability of human, infrastructural and technological resources. Surveillance based on standardized geospatial or other analytical methods should be used by program managers to design, target, monitor and assess the spatio-temporal dynamics of malaria diagnostic resources country-wide.
