RESUMEN
We present a detailed argument for how to integrate, or bridge, systems science thinking and methods with implementation science. We start by showing how fundamental systems science principles of structure, dynamics, information, and utility are relevant for implementation science. Then we examine the need for implementation science to develop and apply richer theories of complex systems. This can be accomplished by emphasizing a causal mechanisms approach. Identifying causal mechanisms focuses on the "cogs and gears" of public health, clinical, and organizational interventions. A mechanisms approach focuses on how a specific strategy will produce the implementation outcome. We show how connecting systems science to implementation science opens new opportunities for examining and addressing social determinants of health and conducting equitable and ethical implementation research. Finally, we present case studies illustrating successful applications of systems science within implementation science in community health policy, tobacco control, health care access, and breast cancer screening.

Orphans and vulnerable children (OVC) in sub-Saharan Africa are at high risk for HIV infection and transmission. HIV prevention and treatment efforts with OVC are hindered by mental health and substance use problems. This randomized controlled trial compared a mental health intervention, Trauma Focused Cognitive Behavioral Therapy (TF-CBT), to an enhanced version of an existing HIV Psychosocial Counseling (PC+) program among 610 adolescents who met PEPFAR criteria for OVC and had HIV risk behaviors in Lusaka, Zambia. Outcomes included HIV risk behaviors (e.g., risky sexual behaviors), mental health (internalizing symptoms, externalizing behaviors, PTSD) and substance use. At 12-month follow-up, there were significant within group reductions in both groups for all outcomes, with the only significant between group difference being for substance use, in which OVC who received TF-CBT had significantly greater reductions than OVC who received PC+. In a subgroup analysis of OVC with high levels of PTSD symptoms, TF-CBT was superior to PC + in reducing internalizing symptoms, functional impairment, and substance use. Findings support TF-CBT for reducing substance use among OVC. Subgroup analysis results suggest that a robust intervention such as TF-CBT is warranted for OVC with significant mental and behavioral health comorbidities. The similar performance of TF-CBT and PC + in the overall sample for risky sexual behavior and mild mental health problems indicates that enhancing existing psychosocial programs, such as PC, with standard implementation factors like having a defined training and supervision schedule (as was done to create PC+) may improve the efficacy of HIV risk reduction efforts.Clinical Trials Number: NCT02054780.

The field of epidemiology's current focus on causal inference follows a quantitative approach and limits research questions to those that are strictly quantifiable. How can epidemiologists study biosociocultural public health problems that they cannot easily quantify? The mixed-methods approach offers a possible solution by incorporating qualitative sociocultural factors as well as the perspective and context from the population under study into quantitative studies. After a pluralist perspective of causal inference, this article provides a guide for epidemiologists interested in applying mixed methods to their observational studies of causal identification and explanation. We begin by reviewing the current paradigms guiding quantitative, qualitative, and mixed methodologies. We then describe applications of convergent and sequential mixed-methods designs to epidemiologic concepts including confounding, mediation, effect modification, measurement, and selection bias. We provide concrete examples of how epidemiologists can use mixed methods to answer research questions of complex bio-socio-cultural health outcomes. We also include a case study of using mixed methods in an observational study design. We describe how mixed methods can enhance how epidemiologists define underlying causal structures. Our alignment of mixed-methods study designs with epidemiologic concepts addresses a major gap in current epidemiology education- how do epidemiologists systematically determine what goes into causal structures?

Alcohol use among persons living with HIV (PWH) can lead to poor disease outcomes. Disclosure of alcohol consumption to physicians is critical to inform HIV care. HIV stigma is associated with poor care engagement, and this relationship is partially mediated by depression. However, less is known about how HIV stigma and depression affect reporting of alcohol use to care providers. We used baseline data from an HIV intervention trial of 330 adult PWH in Baltimore, MD. We fit a path model to examine whether HIV stigma was associated with increased depression symptoms and whether higher levels of depression were, in turn, associated with underreporting of alcohol use to physicians. Among PWH reporting past 6-month alcohol use (n = 182, 55%), 64% met symptom criteria for probable depression, 58% met criteria for hazardous drinking, and 10% reported not disclosing alcohol use to their physician. HIV stigma was associated with higher levels of depression (ß = 0.99, p < .0001); depression was associated with a lower likelihood of alcohol disclosure (ß = -0.04, p < .0001); and depression mediated the indirect pathway from stigma to alcohol disclosure (ß = -0.04, p < .01). Methods to augment or strengthen alcohol self-report may be useful in HIV care, particularly among PWH experiencing HIV stigma and depression.

PURPOSE: In the United States, Hispanic-Latino children reach puberty earlier on average than non-Hispanic white children. Yet among U.S. Hispanic/Latino children, pubertal timing comparisons between immigrant generations have not been made, hence we examined whether pubertal timing differs by immigrant generational status, independent of BMI and acculturation measures. METHODS: Cross-sectional data on 724 boys and 735 girls, aged 10-15 years, from the Hispanic Community Children's Health Study/Study of Latino (SOL) Youth, were used to predict the median ages of thelarche, pubarche, and menarche in girls, and pubarche and voice change in boys, using Weibull survival models, while adjusting for SOL center, BMI, and acculturation. RESULTS: In girls, the first generation began thelarche earlier than second and third generations (median age [years] [95% confidence interval]: 7.4 [6.1, 8.8] vs. 8.5 [7.3, 9.7] and 9.1 [7.6, 10.7], respectively), but began menarche later (12.9 [12.0,137] vs. 11.8 [11.0, 12.5] and 11.6 [10.6, 12.6], respectively). Pubertal timing and tempo for boys did not differ by generational status. CONCLUSIONS: First-generation U.S. Hispanic/Latino girls had the earliest thelarche, latest menarche and longest pubertal tempo, compared to second and third generations. Factors beyond BMI and acculturation may account for the differences in pubertal timing by generational status of U.S. Hispanic/Latino girls.

Objectives. To assess the baseline prevalence of mental health conditions and associated exposures in a cohort of health care workers (HCWs) in Guatemala. Methods. We analyzed baseline information from the 2020 Web-based COVID-19 Health Care Workers Study (HEROES)-Guatemala. Outcomes included mental distress and depressive symptoms. Exposures included COVID-19 experiences, sociodemographic characteristics, and job characteristics. We used crude and adjusted Poisson regression models in our analyses. Results. Of the 1801 HCWs who accepted to participate, 1522 (84.5%) completed the questionnaire; 1014 (66.8%) were women. Among the participants, 59.1% (95% confidence interval [CI] = 56.6, 61.5) screened positive for mental distress and 23% (95% CI = 20.9, 25.2) for moderate to severe depressive symptoms. COVID-19 experiences, sociodemographic characteristics, and job characteristics were associated with the study outcomes. Participants who were worried about COVID-19 infection were at higher risk of mental distress (relative risk [RR] = 1.47; 95% CI = 1.30, 1.66) and depressive symptoms (RR = 1.51; 95% CI = 1.17, 1.96). Similarly, the youngest participants were at elevated risk of mental distress (RR = 1.80; 95% CI = 1.24, 2.63) and depressive symptoms (OR = 4.58; 95% CI = 1.51, 13.87). Conclusions. Mental health conditions are highly prevalent among Guatemalan HCWs. (Am J Public Health. 2022;112(S6):S602-S614. https://doi.org/10.2105/AJPH.2021.306648).

BACKGROUND: Uncontrolled hypertension is a major public health burden and the most common preventable risk factor for cardiovascular diseases in Guatemala and other low- and middle-income countries. Prior to an initial trial that evaluated a hypertension intervention in rural Guatemala, we collected qualitative information on the needs and knowledge gaps of hypertension care within Guatemala's public healthcare system. This analysis applied Kleinman's Explanatory Models of Illness to capture how patients, family members, community-, district-, and provincial-level health care providers and administrators, and national-level health system stakeholders understand hypertension. METHODS: We conducted in-depth interviews with three types of participants: 1) national-level health system stakeholders (n = 17), 2) local health providers and administrators from district, and health post levels (25), and 3) patients and family members (19) in the departments of Sololá and Zacapa in Guatemala. All interviews were conducted in Spanish except for 6 Maya-Kaqchikel interviews. We also conducted focus group discussions with auxiliary nurses (3) and patients (3), one in Maya-Tz'utujil and the rest in Spanish. Through framework and matrix analysis, we compared understandings of hypertension by participant type using the Explanatory Model of Illness domains -etiology, symptoms, pathophysiology, course of illness, and treatment. RESULTS: Health providers and administrators, and patients described hypertension as an illness that spurs from emotional states like sadness, anger, and worry; is inherited and related to advanced age; and produces symptoms that include a weakened body, nerves, pain, and headaches. Patients expressed concerns about hypertension treatment's long-term consequences, despite trying to comply with treatment. Patients stated that they combine biomedical treatment (when available) with natural remedies (teas and plants). Health providers and administrators and family members stated that once patients feel better, they often disengage from treatment. National-level health system stakeholders referred to lifestyle factors as important causes, considered patients to typically be non-compliant, and identified budget limitations as a key barrier to hypertension care. The three groups of participants identified structural barriers to limited hypertension care (e.g., limited access to healthy food and unaffordability of medications). CONCLUSION: As understandings of hypertension vary between types of participants, it is important to describe their similarities and differences considering the role each has in the health system. Considering different perceptions of hypertension will enable better informed program planning and implementation efforts.

Objetivos: Avaliar a prevalência basal de condições de saúde mental e exposições associadas em uma coorte de trabalhadores da saúde (TS) na Guatemala. Métodos: Analisamos as informações da linha de base do estudo on-line sobre trabalhadores da saúde e a COVID-19 (HEROES), realizado em 2020 na Guatemala. Os desfechos incluíram angústia debilitante e sintomas de depressão. As exposições incluíram experiências com a COVID-19, características sociodemográficas e características do trabalho. Usamos em nossas análises modelos de regressão bruta e ajustada de Poisson. Resultados: Dos 1801 TS que concordaram em participar, 1522 (84,5%) preencheram o questionário, sendo que 1014 (66,8%) eram mulheres. Dentre esses participantes, 59,1% (intervalo de confiança [IC] de 95%=56,6; 61,5) apresentaram resultado positivo na triagem de angústia debilitante e 23% (IC 95%=20,9, 25,2) apresentaram resultado positivo para sintomas de depressão moderados a graves. Experiências com COVID-19, e características sociodemográficas e de trabalho apresentaram associação com os resultados do estudo. Os participantes que estavam preocupados com infecção por COVID-19 apresentaram maior risco de angústia debilitante (risco relativo [RR]=1,47; IC95%=1,30; 1,66) e sintomas de depressão (RR=1,51; IC 95% =1,17; 1,96). Da mesma maneira, os participantes mais jovens apresentaram alto risco de apresentarem angústia debilitante (RR=1,80; IC 95%=1,24; 2,63) e sintomas de depressão (OR=4,58; IC 95%=1,51; 13,87). Conclusões: Condições de saúde mental são altamente prevalentes entre os guatemaltecos.
RESUMEN
Objectives. To describe excess mortality during the COVID-19 pandemic in Guatemala during 2020 by week, age, sex, and place of death. Methods. We used mortality data from 2015 to 2020, gathered through the vital registration system of Guatemala. We calculated weekly mortality rates, overall and stratified by age, sex, and place of death. We fitted a generalized additive model to calculate excess deaths, adjusting for seasonality and secular trends and compared excess deaths to the official COVID-19 mortality count. Results. We found an initial decline of 26% in mortality rates during the first weeks of the pandemic in 2020, compared with 2015 to 2019. These declines were sustained through October 2020 for the population younger than 20 years and for deaths in public spaces and returned to normal from July onward in the population aged 20 to 39 years. We found a peak of 73% excess mortality in mid-July, especially in the population aged 40 years or older. We estimated a total of 8036 excess deaths (95% confidence interval = 7935, 8137) in 2020, 46% higher than the official COVID-19 mortality count. Conclusions. The extent of this health crisis is underestimated when COVID-19 confirmed death counts are used. (Am J Public Health. 2021;111(10): 1839-1846. https://doi.org/10.2105/AJPH.2021.306452).

BACKGROUND: Uncontrolled hypertension represents a substantial and growing burden in Guatemala and other low and middle-income countries. As a part of the formative phase of an implementation research study, we conducted a needs assessment to define short- and long-term needs and opportunities for hypertension services within the public health system. METHODS: We conducted a multi-method, multi-level assessment of needs related to hypertension within Guatemala's public system using the World Health Organization's health system building blocks framework. We conducted semi-structured interviews with stakeholders at national (n = 17), departmental (n = 7), district (n = 25), and community (n = 30) levels and focus groups with patients (3) and frontline auxiliary nurses (3). We visited and captured data about infrastructure, accessibility, human resources, reporting, medications and supplies at 124 health posts and 53 health centers in five departments of Guatemala. We conducted a thematic analysis of transcribed interviews and focus group discussions supported by matrix analysis. We summarized quantitative data observed during visits to health posts and centers. RESULTS: Major challenges for hypertension service delivery included: gaps in infrastructure, insufficient staffing and high turnover, limited training, inconsistent supply of medications, lack of reporting, low prioritization of hypertension, and a low level of funding in the public health system overall. Key opportunities included: prior experience caring for patients with chronic conditions, eagerness from providers to learn, and interest from patients to be involved in managing their health. The 5 departments differ in population served per health facility, accessibility, and staffing. All but 7 health posts had basic infrastructure in place. Enalapril was available in 74% of health posts whereas hydrochlorothiazide was available in only 1 of the 124 health posts. With the exception of one department, over 90% of health posts had a blood pressure monitor. CONCLUSIONS: This multi-level multi-method needs assessment using the building blocks framework highlights contextual factors in Guatemala's public health system that have been important in informing the implementation of a hypertension control trial. Long-term needs that are not addressed within the scope of this study will be important to address to enable sustained implementation and scale-up of the hypertension control approach.

BACKGROUND: A growing literature base supports the use of tests developed in high-income countries to assess children in low resource settings when carefully translated, adapted, and applied. Evaluation of psychometric properties of adapted and translated measures within populations is necessary. The current project sought to evaluate the reliability and validity of an adapted and translated version of the Mullen Scales of Early Learning (AT-MSEL) in rural Guatelama. METHODS: The reliability and validity of the AT-MSEL in rural Guatemala were analyzed for children ages 0-5 years. RESULTS: Interrater reliability coefficients (ICC = 0.99-1.0) and internal consistency (Cronbach's alpha = 0.91-0.93) were excellent for all subscales. General linear models utilizing paired data showed consistency between standard scores (p < 0.0001). Mean raw scores increased with chronological age, as expected. Across age groups, subscales were significantly, positively correlated with one another (p < 0.05 - < 0.001) with one exception, visual reception and expressive language at the 0-10 month age range (p = 0.43). CONCLUSIONS: The AT- MSEL showed strong psychometric properties in a sample of young children in rural Guatemala. Findings demonstrate that the AT-MSEL can be used validly and reliably within this specific population of children. This work supports the concept that tests developed in high-income countries can be used to assess children in low resource settings when carefully translated, adapted and applied.

BACKGROUND: Children in low- and lower middle income countries (LMICs) often have poorer language skills compared with children from high-income countries. Limited availability of culturally and linguistically appropriate assessment measures in LMICs, especially for young children, can hinder early identification and prevention efforts. Here, we describe receptive language (RL) skills among young children in rural Guatemala and report on the validity of a translated and culturally adapted developmental measure of RL. METHODS: Children (n = 157; m = 53.6 months, range = 42-68 months) enrolled in a prospective cohort study of postnatally acquired Zika virus infection were administered the Test de Vocabulario en Imagenes Peabody (TVIP) and the RL scale from a translated and adapted version of the Mullen Scales of Early Learning (MSEL). Performance on the TVIP was compared with the Latin American normative sample. Correlational analysis examined the relationship between performance on the TVIP and the MSEL-RL. RESULTS: Mean scores were significantly below the normative sample mean on the TVIP, t(126) = -11.04, p < .001; d = 1.00. Performance on the TVIP among children who passed the practice items (n = 127) was significantly positively associated with performance on the MSEL-RL (r = .50, p < .001), but not significantly associated with age or gender. Older age (p < .0001) and female gender (p = .018) were associated with passing the TVIP practice items. CONCLUSIONS: Delays in RL vocabulary were identified among young children in rural Guatemala on the TVIP. The association between scores on the TVIP and the RL scale of the MSEL provides preliminary support for the construct validity of this translated and adapted version of the MSEL.

BACKGROUND: With their increasing availability in resource-limited settings, mobile phones may provide an important tool for participatory syndromic surveillance, in which users provide symptom data directly into a centralized database. OBJECTIVE: We studied the performance of a mobile phone app-based participatory syndromic surveillance system for collecting syndromic data (acute febrile illness and acute gastroenteritis) to detect dengue virus and norovirus on a cohort of children living in a low-resource and rural area of Guatemala. METHODS: Randomized households were provided with a mobile phone and asked to submit weekly reports using a symptom diary app (Vigilant-e). Participants reporting acute febrile illness or acute gastroenteritis answered additional questions using a decision-tree algorithm and were subsequently visited at home by a study nurse who performed a second interview and collected samples for dengue virus if confirmed acute febrile illness and norovirus if acute gastroenteritis. We analyzed risk factors associated with decreased self-reporting of syndromic data using the Vigilant-e app and evaluated strategies to improve self-reporting. We also assessed agreement between self-report and nurse-collected data obtained during home visits. RESULTS: From April 2015 to June 2016, 469 children in 207 households provided 471 person-years of observation. Mean weekly symptom reporting rate was 78% (range 58%-89%). Households with a poor (<70%) weekly reporting rate using the Vigilant-e app during the first 25 weeks of observation (n=57) had a greater number of children (mean 2.8, SD 1.5 vs mean 2.5, SD 1.3; risk ratio [RR] 1.2, 95% CI 1.1-1.4), were less likely to have used mobile phones for text messaging at study enrollment (61%, 35/57 vs 76.7%, 115/150; RR 0.6, 95% CI 0.4-0.9), and were less likely to access care at the local public clinic (35%, 20/57 vs 67.3%, 101/150; RR 0.4, 95% CI 0.2-0.6). Parents of female enrolled participants were more likely to have low response rate (57.1%, 84/147 vs 43.8%, 141/322; RR 1.4, 95% CI 1.1-1.9). Several external factors (cellular tower collapse, contentious elections) were associated with periods of decreased reporting. Poor response rate (<70%) was associated with lower case reporting of acute gastroenteritis, norovirus-associated acute gastroenteritis, acute febrile illness, and dengue virus-associated acute febrile illness (P<.001). Parent-reported syndromic data on the Vigilant-e app demonstrated agreement with nurse-collected data for fever (kappa=.57, P<.001), vomiting (kappa=.63, P<.001), and diarrhea (kappa=.61, P<.001), with decreased agreement as the time interval between parental report and nurse home visit increased (<1 day: kappa=.65-.70; ≥2 days: kappa=.08-.29). CONCLUSIONS: In a resource-limited area of rural Guatemala, a mobile phone app-based participatory syndromic surveillance system demonstrated a high reporting rate and good agreement between parental reported data and nurse-reported data during home visits. Several household-level and external factors were associated with decreased syndromic reporting. Poor reporting rate was associated with decreased syndromic and pathogen-specific case ascertainment.

BACKGROUND: Most implementation science resources (e.g., taxonomies) are published in English. Linguistic inaccessibility creates a barrier to the conduct of implementation research among non-English-speaking populations, so translation of resources is needed. Translation into Spanish can facilitate widespread reach, given the large proportion of Spanish speakers around the world. This research aimed to systematically translate the Expert Recommendations for Implementation Change (ERIC) compilation into Spanish as an exemplar for the linguistic translation process. METHODS: Using the World Health Organization guidelines, this work translated the ERIC compilation strategy names, short definitions, and thematic clusters through a three-step process: 1) forward translation into Spanish by a native Spanish-speaking implementation scientist, 2) back-translation into English by a bilingual global health researcher, and 3) piloting via virtual focus group discussions with bilingual researchers not conducting implementation research. To achieve a generalizable translation, recruitment targeted a multicultural group of Spanish-speaking researchers. At the conclusion of each step, the transdisciplinary research team (N = 7) met to discuss discrepancies and refine translations. The Spanish version of the ERIC compilation was finalized through group consensus. Reflections from research team meetings and focus group discussions were synthesized qualitatively. RESULTS: Given that dialectical nuances exist between Spanish-speaking regions, efforts prioritized universally accepted terminology. Team discussions focused on difficult translations, word choice, and clarity of concepts. Seven researchers participated in two focus groups, where discussion surrounded clarity of concepts, alternative word choice for Spanish translations, linguistic formality, grammar, and conciseness. Translation difficulties highlighted lack of precision in implementation science terminology, and the lack of conceptual clarity of words underscored limitations in the application of the compilation. CONCLUSIONS: The work demonstrated the feasibility of translating implementation science resources. As one of the first systematic efforts to translate implementation resources, this study can serve as a model for additional efforts, including translation into other languages and the expansion to conceptual modifications. Further, this work yielded insights into the need to provide conceptual clarity in implementation science terminology. Importantly, the development of Spanish resources will increase access to conduct implementation research among Spanish-speaking populations.
RESUMEN
Refugees and migrants experience an elevated risk for mental health problems and face significant barriers to receiving services. Interpersonal counseling (IPC-3) is a three-session intervention that can be delivered by non-specialists to provide psychological support and facilitate referrals for individuals in need of specialized care. We piloted IPC-3 delivered remotely by eight Venezuelan refugee and migrant women living in Peru. These counselors provided IPC-3 to Venezuelan refugee and migrant clients in Peru (n = 32) who reported psychological distress. Clients completed assessments of mental health symptoms at baseline and one-month post-intervention. A subset of clients (n = 15) and providers (n = 8) completed post-implementation qualitative interviews. Results showed that IPC-3 filled a gap in the system of mental health care for refugees and migrants in Peru. Some adaptations were made to IPC-3 to promote its relevance to the population and context. Non-specialist providers developed the skills and confidence to provide IPC-3 competently. Clients displayed large reductions in symptoms of depression (d = 1.1), anxiety (d = 1.4), post-traumatic stress (d = 1.0), and functional impairment (d = 0.8). Remote delivery of IPC-3 by non-specialists appears to be a feasible, acceptable, and appropriate strategy to address gaps and improve efficiency within the mental health system and warrants testing in a fully powered effectiveness study.

BACKGROUND: The COVID-19 pandemic necessitated rapid changes in healthcare delivery in Guatemala's public primary care settings. A new hypertension program, implemented as part of a type 2 hybrid trial since 2019, exemplifies an implementation effort amidst a changing context in an under-resourced setting. We assessed the implementation of an evidence-based intervention (EBI; protocol-based hypertension treatment) and one of its main implementation strategies (team-based collaborative care), raising implications for health equity and sustainability. We present innovative application of systems thinking visuals. METHODS: Conducting a convergent mixed methods analysis, we assessed implementation in response to contextual changes across five Ministry of Health (MoH) districts at the pandemic's onset. Utilizing quantitative programmatic data and qualitative interviews with stakeholders (n=18; health providers, administrators, study staff), we evaluated dimensions of "Reach, Effectiveness, Adoption, Implementation and Maintenance," RE-AIM (Reach, Implementation delivery + adaptations), and "Practical Robust Implementation and Sustainability Model," PRISM (Organizational perspective on the EBI, Fit, Implementation and sustainability infrastructure) frameworks. We assessed representativeness by comparing participants to census data. To assess implementation delivery, we built behavior-over-time (BOT) graphs with quantitative programmatic data (July 2019-July 2021). To assess adaptations and contextual changes, we performed matrix-based thematic qualitative analysis. We converged quantitative implementation delivery data + qualitative adaptations data in joint displays. Finally, we analyzed qualitative and quantitative results across RE-AIM/PRISM and health districts to identify equity and sustainability considerations. RESULTS: Contextual factors that facilitated program delivery included the perception that the EBI was beneficial, program champions, and staff communication. Key barriers to implementation delivery included competition with other primary care activities and limited implementation infrastructure (e.g., equipment, medications). Contextual changes related to COVID-19 hindered implementation delivery, threatened sustainability, and may have exacerbated inequities. However, adaptations that were planned enhanced implementation delivery and may have supported improved equity and sustainability. CONCLUSIONS: Recognition of an EBI's benefits and program champions are important for supporting initial uptake. The ability to plan adaptations amid rapid contextual changes has potential advantages for sustainability and equitable delivery. Systems thinking tools and mixed methods approaches may shed light on the relations between context, adaptations, and equitable and sustainable implementation. TRIAL REGISTRATION: NCT03504124.
RESUMEN
Stunting (<-2 SD of length- or height-for-age on WHO growth curves) is the most used predictor of child neurodevelopmental (ND) risk. Occipitofrontal head circumference (OFC) may be an equally feasible, but more direct and robust predictor. We explored association of the two measurements with ND outcome, separately and combined, and examined if cutoffs are more efficacious than continuous measures in predicting ND risk. Infants and young children in rural Guatemala (n = 642; age range = 0.1-35.9 months) were enrolled in a prospective natural history study, and their ND was tested using the Mullen Scales of Early Learning (MSEL) longitudinally. Length- or height-for-age and OFC-for-age were calculated. We performed age-adjusted multivariable regression analyses to explore the association between 1) length or height and ND, 2) OFC and ND, and 3) both length or height and OFC combined, with ND; concurrently, predictively, and longitudinally, as continuous variables and using WHO z-score cutoffs. Continuous length- or height-for-age and OFC z-scores were more strongly associated with MSEL than the traditional -2 SD WHO cutoff. The combination of height-for-age z-score and OFC z-score was consistently, strongly associated with the MSEL Early Learning Composite concurrently (p-values 0.0004-0.11), predictively (p-value 0.001-0.07), with the exception of the 18-24 months age group which had very few records, and in the longitudinal model (p-value <0.0001-0.004). The combination of continuous length- or height-for-age and OFC shows additional utility in estimating ND risk in infants and young children. Measurement of OFC may improve precision of prediction of ND risk in infants and young children.

Background: The COVID-19 pandemic necessitated rapid changes in the delivery of care across public primary care settings in rural Guatemala in 2020. In response, a hypertension program implemented within the public primary care system required multiple adaptations, providing an illustrative example of dynamic implementation amidst changing context in an under-resourced setting. This study describes the evolvability of an evidence-based intervention (EBI; protocol-based hypertension treatment) and one of its main implementation strategies (team-based collaborative care) during the COVID-19 pandemic and discusses implications for health equity and sustainability. Methods: This convergent mixed methods analysis assessed implementation across five Ministry of Health districts during the initial phase of the pandemic. Qualitative and quantitative data were collected, analyzed, and integrated, informed by the RE-AIM (Reach, Effectiveness, Adoption, Implementation Maintenance) Framework's extension for sustainability, and its contextual enhancement, PRISM (Pragmatic, Robust, Implementation and Sustainability Model). For RE-AIM, we focused on the "Implementation" domain, operationalizing it qualitatively as continued delivery and adaptations to the EBI and implementation strategy, and quantitatively as the extent of delivery over time. We conducted 18 in-depth interviews with health providers / administrators (n=8) and study staff (n=10) and performed a matrix-based thematic-analysis. Qualitative results informed the selection of quantitative implementation summarized as behavior over time graphs. Quantitative implementation data and illustrative quotes are presented as joint displays. Results: In relation to implementation, several organic adaptations hindered delivery, threatened sustainability, and may have exacerbated health inequities. Planned adaptations enhanced program delivery and may have supported improved equity and sustainability. Salient PRISM factors that influenced implementation included "Organizational perspective of the EBI", "Fit" and "Implementation and sustainability infrastructure". Facilitators to continued delivery included the perception that the EBI is beneficial, program champions, and healthcare team organization. Barriers included the perception that the EBI is complicated, competition with other primary care activities, and temporary suspension of services due to COVID-19. Conclusions: Multi-level contextual changes led to numerous adaptations of the EBI and implementation strategy. Systems thinking approaches may shed light on how a program's sustainability and its equitable delivery are influenced by adaptations over time in response to dynamic, multi-level contextual factors. Trial registration: NCT03504124.
RESUMEN
BACKGROUND: Few real-world examples exist of how best to select and adapt implementation strategies that promote sustainability. We used a collaborative care (CC) use case to describe a novel, theory-informed, stakeholder engaged process for operationalizing strategies for sustainability using a behavioral lens. METHODS: Informed by the Dynamic Sustainability Framework, we applied the Behaviour Change Wheel to our prior mixed methods to identify key sustainability behaviors and determinants of sustainability before specifying corresponding intervention functions, behavior change techniques, and implementation strategies that would be acceptable, equitable and promote key tenets of sustainability (i.e., continued improvement, education). Drawing on user-centered design principles, we enlisted 22 national and local stakeholders to operationalize and adapt (e.g., content, functionality, workflow) a multi-level, multi-component implementation strategy to maximally target behavioral and contextual determinants of sustainability. RESULTS: After reviewing the long-term impact of early implementation strategies (i.e., external technical support, quality monitoring, and reimbursement), we identified ongoing care manager CC delivery, provider treatment optimization, and patient enrollment as key sustainability behaviors. The most acceptable, equitable, and feasible intervention functions that would facilitate ongoing improvement included environmental restructuring, education, training, modeling, persuasion, and enablement. We determined that a waiting room delivered shared decision-making and psychoeducation patient tool (DepCare), the results of which are delivered to providers, as well as ongoing problem-solving meetings/local technical assistance with care managers would be the most acceptable and equitable multi-level strategy in diverse settings seeking to sustain CC programs. Key adaptations in response to dynamic contextual factors included expanding the DepCare tool to incorporate anxiety/suicide screening, triage support, multi-modal delivery, and patient activation (vs. shared decision making) (patient); pairing summary reports with decisional support and yearly onboarding/motivational educational videos (provider); incorporating behavioral health providers into problem-solving meetings and shifting from billing support to quality improvement and triage (system). CONCLUSION: We provide a roadmap for designing behavioral theory-informed, implementation strategies that promote sustainability and employing user-centered design principles to adapt strategies to changing mental health landscapes.
