RESUMEN

HIV stigma is comprised of several beliefs, including transmission fears and moral judgments against affected communities. We examined the relationships among HIV-related stigma beliefs, endorsement of coercive measures for people living with HIV (PLWH), and intentions to discriminate. We sought to understand to what degree the different stigma beliefs shape support for restrictive policies and discriminatory intentions. Data were drawn from the baseline assessment of DriSti, a cluster randomized controlled trial of an HIV stigma reduction intervention in Indian healthcare settings (NCT02101697). Participants completed measures assessing transmission fears and moral judgments of HIV, endorsement of coercive measures against PLWH (public disclosure of HIV status, refusal of healthcare services, marriage and family restrictions, required testing, and sharing of HIV information in a clinic), and intentions to discriminate against PLWH in professional and personal settings. We utilized multivariate regression modeling with backward elimination to identify the coercive measures and behavioral intentions most strongly associated with moral judgments. 1540 ward staff members completed the assessment. Participants had relatively high perceptions of transmission fears (M = 1.92, SD = 0.79) and moral judgments (M = 1.69, SD = 0.83); endorsed more intentions to discriminate in professional (M = 6.54, SD = 2.28) than personal settings (M = 2.07, SD = 1.49), and endorsed approximately half of all coercive measures (M = 9.47, SD = 2.68). After controlling for transmission fears, perceptions of stronger moral judgments against PLWH were significantly associated with higher endorsement of coercive measures related to refusing services (ß = 0.10, t = 4.14, p < 0.001) and sharing patients' HIV status in clinics (ß = 0.07, t = 3.04, p = 0.002), as well as with stronger behavioral intentions to discriminate in professional settings (ß = 0.05, t = 2.20, p = 0.022). HIV stigma interventions for hospital-based ward staff in India need to focus on both transmission fears and moral judgments that underlie prejudicial beliefs. While the moral judgments are not technically related to risk in a hospital setting, our findings suggest that personnel will continue to discriminate in their professional work so long as these beliefs bear on their decisions and actions.

RESUMEN

The study aims to define the sex-based reference data for muscle mass and strength among healthy young Indians and to compare the data from the present study with available literature. Healthy Indian adults (n = 100) aged between 18 and 40 years were recruited. The assessment of muscle mass and strength was performed. The body cell mass (BCM), fat-free mass, and muscle strength parameters were significantly higher among males compared to females (P < 0.001). A comparison of the current study data with the available literature showed that though BCM was comparable, Indians demonstrated a significantly lower isometric peak torque (P < 0.001 for both sexes). These findings suggest that Indians tend to have a lower muscle strength compared to the Western population, despite having a comparable BCM content.

RESUMEN

Health facility stigma impedes HIV care and treatment. Worry of contracting HIV while caring for people living with HIV is a key driver of health facility stigma, however evidence for this relationship is largely cross-sectional. This study evaluates this relationship longitudinally amongst nursing students and ward staff in India. Worry of contracting HIV and other known predictors of intent to discriminate were collected at baseline and 6 months in 916 nursing students and 747 ward staff. Using fixed effects regression models, we assessed the effect of key predictors on intent to discriminate over a 6-month period. Worry of contracting HIV predicted intent to discriminate for nursing students and ward staff in care situations with low and high-risk for bodily fluid exposure, confirming prior cross-sectional study results and underscoring the importance of addressing worry of contracting HIV as part of health facility HIV stigma-reduction interventions.

RESUMEN

HIV stigma has long been recognized as a significant barrier in the worldwide fight against HIV. Across cultures, stigma has been shown to cause psychological distress and act as a barrier to engagement in care. Health professionals can serve as a crucial source of HIV stigma, with drivers that include fears and transmission misconceptions and pre-existing negative attitudes towards marginalized groups. To increase their impact, stigma reduction interventions need to be scalable and sustainable as well as adaptable to different cultural contexts. The DriSti intervention was designed to meet these needs through an easily adaptable, mostly tablet-administered, interactive intervention delivered to ward staff (n = 1,557) and nursing students (n = 1,625) in 62 Indian institutions, using a cRCT design, with wait-list controls. Six-month outcome analyses, showed significant reductions in misconceptions (p < .001) and worry about acquiring HIV at work (p < .001). Intervention participants also reported significantly greater reductions in endorsement of coercive policies (p < .001) and in the number of situations in which they intended to discriminate against PLWH (p < .001) than control participants. This brief, scaleable intervention could be adapted for similar populations in the region, using different mHealth platforms and thus has important implications for current global stigma reduction initiatives and training curricula.

RESUMEN

BACKGROUND: There is a need to identify and test low-cost approaches for cardiovascular disease (CVD) risk reduction that can enable health systems to achieve such a strategy. OBJECTIVE: Community health workers (CHWs) are an integral part of health-care delivery system in lower income countries. Our aim was to assess impact of CHW based interventions in reducing CVD risk factors in rural households in India. METHODS: We performed an open-label cluster-randomized trial in 28 villages in 3 states of India with the household as a unit of randomization. Households with individuals at intermediate to high CVD risk were randomized to intervention and control groups. In the intervention group, trained CHWs delivered risk-reduction advice and monitored risk factors during 6 household visits over 12 months. Households in the non-intervention group received usual care. Primary outcomes were a reduction in systolic BP (SBP) and adherence to prescribed BP lowering drugs. RESULTS: We randomized 2312 households (3261 participants at intermediate or high risk) to intervention (1172 households) and control (1140 households). At baseline prevalence of tobacco use (48.5%) and hypertension (34.7%) were high. At 12 months, there was significant decline in SBP (mmHg) from baseline in both groups- controls 130.3 ±â€¯21 to 128.3 ±â€¯15; intervention 130.3 ±â€¯21 to 127.6 ±â€¯15 (P < .01 for before and after comparison) but there was no difference between the 2 groups at 12 months (P = .18). Adherence to antihypertensive drugs was greater in intervention vs control households (74.9% vs 61.4%, P = .001). CONCLUSION: A 12-month CHW-led intervention at household level improved adherence to prescribed drugs, but did not impact SBP. To be more impactful, a more comprehensive solution that addresses escalation and access to useful therapies is needed.

RESUMEN

Electronic Health Record (EHR) use in India is generally poor, and structured clinical information is mostly lacking. This work is the first attempt aimed at evaluating unstructured text mining for extracting relevant clinical information from Indian clinical records. We annotated a corpus of 250 discharge summaries from an Intensive Care Unit (ICU) in India, with markups for diseases, procedures, and lab parameters, their attributes, as well as key demographic information and administrative variables such as patient outcomes. In this process, we have constructed guidelines for an annotation scheme useful to clinicians in the Indian context. We evaluated the performance of an NLP engine, Cocoa, on a cohort of these Indian clinical records. We have produced an annotated corpus of roughly 90 thousand words, which to our knowledge is the first tagged clinical corpus from India. Cocoa was evaluated on a test corpus of 50 documents. The overlap F-scores across the major categories, namely disease/symptoms, procedures, laboratory parameters and outcomes, are 0.856, 0.834, 0.961 and 0.872 respectively. These results are competitive with results from recent shared tasks based on US records. The annotated corpus and associated results from the Cocoa engine indicate that unstructured text mining is a viable method for cohort analysis in the Indian clinical context, where structured EHR records are largely absent.

RESUMEN

The aim of this study is to increase hand sanitizer usage among healthcare workers by developing and implementing a low-cost intervention using RFID and wireless mesh networks to provide real-time alarms for increasing hand hygiene compliance during opportune moments in an open layout Intensive Care Unit (ICU). A wireless, RFID based system was developed and implemented in the ICU. The ICU beds were divded into an intervention arm (n = 10) and a control arm (n = 14). Passive RFID tags were issued to the doctors, nurses and support staff of the ICU. Long range RFID readers were positioned strategically. Sensors were placed beneath the hand sanitizers to record sanitizer usage. The system would alert the HCWs by flashing a light if an opportune moment for hand sanitization was detected. A significant increase in hand sanitizer use was noted in the intervention arm. Usage was highest during the early part of the workday and decreased as the day progressed. Hand wash events per person hour was highest among the ancilliary staff followed by the doctors and nurses. Real-time feedback has potential to increase hand hygiene compliance among HCWs. The system demonstrates the possibility of automating compliance monitoring in an ICU with an open layout.

RESUMEN

BACKGROUND: India has a wide range of nutrition and health problems which require professionals with appropriate skills, knowledge and trans-disciplinary collaborative abilities to influence policy making at the national and global level. METHODS: The Bangalore Boston Nutrition Collaborative (BBNC) was established as collaboration between St. John's Research Institute (SJRI), Harvard School of Public Health and Tufts University, with a focus on nutrition research and training. The goals of the BBNC were to conduct an interdisciplinary course, develop web-based courses and identify promising Indian students and junior faculty for graduate training in Boston. RESULTS: From 2010, an annual two-week short course in nutrition research methods was conducted on the SJRI campus taught by international faculty from Indian and US universities. More than 100 students applied yearly for approximately 30 positions. The course had didactic lectures in the morning and practical hands-on sessions in the afternoon. Student rating of the course was excellent and consistent across the years. The ratings on the design and conduct of the course significantly improved (p <0.001) from 2010 to 2012. Through open-ended questions, students reported the main strengths of the course to be the excellent faculty and practical "hands-on" sessions. A web based learning system TYRO, was developed, which can be used for distance learning. Four faculty members/graduate students from SJRI have visited Boston for collaborative research efforts. CONCLUSION: The BBNC has become a well-established capacity building and research training program for young professionals in nutrition and global health. Efforts are ongoing to secure long term funding to sustain and expand this collaboration to deliver high quality nutrition and global health education enabled by information and communication technologies.

RESUMEN

BACKGROUND: mHealth (mobile health) systems have been deployed widely in low- and middle-income countries (LMICs) for health system strengthening, requiring considerable resource allocation. However, most solutions have not achieved scale or sustainability. Poor usability and failure to address perceived needs are among the principal reasons mHealth systems fail to achieve acceptance and adoption by health care workers. A human-centered design approach to improving mHealth system use requires an exploration of users' perceptions of mHealth systems, including the environmental, user-related, and technological aspects of a system. At present, there is a dearth of contextually intelligent tools available to mHealth developers that can guide such exploration before full-scale development and deployment. OBJECTIVE: To develop a tool to aid optimization of mHealth solutions in LMICs to facilitate human-centered design and, consequently, successful adoption. METHODS: We collated findings and themes from key qualitative studies on mHealth deployment in LMICs. We then used the Informatics Stack framework by Lehmann to label, sort, and collate findings and themes into a list of questions that explore the environment, users, artifacts, information governance, and interoperability of mHealth systems deployed in LMICs. RESULTS: We developed the Vinyasa Tool to aid qualitative research about the need and usability of mHealth solutions in LMICs. The tool is a guide for focus group discussions and key informant interviews with community-based health care workers and primary care medical personnel who use or are expected to use proposed mHealth solutions. The tool consists of 71 questions organized in 11 sections that unpack and explore multiple aspects of mHealth systems from the perspectives of their users. These include the wider world and organization in which an mHealth solution is deployed; the roles, functions, workflow, and adoption behavior of a system's users; the security, privacy, and interoperability afforded by a system; and the artifacts of an information system-the data, information, knowledge, algorithms, and technology that constitute the system. The tool can be deployed in whole or in part, depending on the context of the study. CONCLUSIONS: The Vinyasa Tool is the first such comprehensive qualitative research instrument incorporating questions contextualized to the LMIC setting. We expect it to find wide application among mHealth developers, health system administrators, and researchers developing and deploying mHealth tools for use by patients, providers, and administrators. The tool is expected to guide users toward human-centered design with the goal of improving relevance, usability, and, therefore, adoption.

RESUMEN

BACKGROUND: Of every 10 women in rural India, 1 suffers from a common mental disorder such as depression, and untreated depression is associated with significant morbidity and mortality. Several factors lead to a large treatment gap, specifically for women in rural India, including stigma, lack of provider mental health workforce, and travel times. There is an urgent need to improve the rates of detection and treatment of depression among women in rural India without overburdening the scarce mental health resources. OBJECTIVE: We propose to develop, test, and deploy a mental health app, MITHRA (Multiuser Interactive Health Response Application), for depression screening and brief intervention, designed for use in women's self-help groups (SHGs) in rural India. METHODS: We will use focus groups with SHG members and community health workers to guide the initial development of the app, followed by iterative modification based on input from a participatory design group consisting of proposed end users of the app (SHG members). The final version of the app will then be deployed for testing in a pilot cluster randomized trial, with 3 SHGs randomized to receive the app and 3 to receive enhanced care as usual. RESULTS: This study was funded in June 2021. As of September 2022, we have completed both focus groups, 1 participatory design group, and app development. CONCLUSIONS: Delivering app-based depression screening and treatment in community settings such as SHGs can address stigma and transportation-related barriers to access to depression care and overcome cultural and contextual barriers to mobile health use. It can also address the mental health workforce shortage. If we find that the MITHRA approach is feasible, we will test the implementation and effectiveness of MITHRA in multiple SHGs across India in a larger randomized controlled trial. This approach of leveraging community-based organizations to improve the reach of depression screening and treatment is applicable in rural and underserved areas across the globe.

RESUMEN

Context: Standard precautions (SP) are infection prevention practices universally used during patient care to lower infection transmission. Aims: The aim of the study was to (1) assess Indian ward attendants' (WAs) knowledge, perceived efficacy, and self-efficacy regarding SP and (2) examine correlates of SP self-efficacy and intent to use unnecessary precautions during care of people living with HIV. Subjects and Methods: Data are sourced from a face-to-face baseline survey of a stigma-reduction trial among 1859 WAs from Indian hospitals. Percentages were used to describe categorical variables means and standard deviations for continuous variables. Multiple regressions examined associations between measures. Results: WAs who had heard of SP had 44% higher odds of confidently using SP than those who had not heard of them. Those aware of universal SP use were 43% more likely to feel confident in using SP but also reported greater intent to use unnecessary precautions. Conclusions: Hospitals could implement SP training for WAs, as their knowledge of universal use was lacking.

RESUMEN

Background and objective: Standard Precautions (SP) are infection control procedures universally applicable to every patient. Though SP reduces disease transmission, their implementation is dependent on the knowledge and skills of healthcare workers (HCWs). Poor knowledge regarding the appropriate use of SP can cause fear among HCWs, leading to stigma and discrimination while treating people living with HIV (PLWH). Stigma and discrimination are known barriers for PLWH to access HIV care services. The aim of the study was to assess nursing student knowledge of SP, SP self-efficacy and SP perceived efficacy of nursing students, and (2) to assess the association between SP knowledge, perceived efficacy, and intention to utilize unwarranted precautions, like using double gloves while treating PLWH. Methods: This paper analyzes baseline (non-randomized) data of a cluster randomized controlled trial amongst 1868 Indian nursing students. Data was collected using computer-administered structured questionnaire. The associations between the measures were done using multiple, logistic and poisson regression models. Results: Although 97% nursing students could identify SP, only 35.5% understood that they need to be used with all patients. Awareness of the importance of using SP with all patients was positively associated with self-efficacy. Students performing high-risk tasks frequently were significantly more likely to be confident in their ability to correctly use SP, but also had higher intention to use unwarranted precautions. Conclusions: Existing teaching and training programs for HCWs need to provide clear guidelines and emphasize on the correct use of SP with all patients. This will increase both skills and confidence in their abilities (self-efficacy).

RESUMEN

BACKGROUND: HIV stigma in health care settings acts as a significant barrier to health care. Stigma drivers among health professionals include transmission fears and misconceptions and pre-existing negative attitudes toward marginalized groups vulnerable to HIV. The DriSti intervention, consisted of 2 sessions with videos and interactive exercises on a computer tablet and one interactive face-to-face group session, mostly tablet administered, was designed to target key stigma drivers that included instrumental stigma, symbolic stigma, transmission misconceptions and blame to reduce HIV stigma, and discrimination among nursing students (NS) and ward staff and tested in a cluster randomized trial. SETTING: This report focuses on second and third year NS recruited from a range of nursing schools that included private, nonprofit, and government-run nursing schools in south India. RESULTS: Six hundred seventy-nine NS received intervention and 813 NS were in the wait-list control group. Twelve months outcome analyses showed significant reduction among intervention participants in endorsement of coercive policies (P < 0.001) and in the number of situations in which NS intended to discriminate against PLWH (P < 0.001). Mediation analysis revealed that the effects of intervention on endorsement of coercive policies and intent to discriminate against PLWH were partially mediated by reductions in key stigma drivers. CONCLUSIONS: This brief scalable stigma reduction intervention targeting key stigma drivers fills a critical gap in identifying the mechanistic pathways that aid in stigma reduction among health professionals.

RESUMEN

Integration of mobile phone technology into HIV care holds potential, particularly in resource-constrained settings. Clinic attendees in urban and rural South India were surveyed to ascertain usage of mobile phones and perceptions of their use as an adherence aid. Mobile phone ownership was high at 73%; 26% reported shared ownership. A high proportion (66%) reported using phones to call their healthcare provider. There was interest in weekly telephonic automated voice reminders to facilitate adherence. Loss of privacy was not considered a deterrent. The study presents important considerations in the design of a mobile phone-based adherence intervention in India.

RESUMEN

Antimicrobial resistance (AMR) is a fundamental global concern analogous to climate change threatening both public health and global development progress. Infections caused by antimicrobial-resistant pathogens pose serious threats to healthcare and human capital. If the increasing rate of AMR is left uncontrolled, it is estimated that it will lead to 10 million deaths annually by 2050. This global epidemic of AMR necessitates radical interdisciplinary solutions to better detect antimicrobial susceptibility and manage infections. Rapid diagnostics that can identify antimicrobial-resistant pathogens to assist clinicians and health workers in initiating appropriate treatment are critical for antimicrobial stewardship. In this review, we summarize different technologies applied for the development of rapid diagnostics for AMR and antimicrobial susceptibility testing (AST). We briefly describe the single-cell technologies that were developed to hasten the AST of infectious pathogens. Then, the different types of genotypic and phenotypic techniques and the commercially available rapid diagnostics for AMR are discussed in detail. We conclude by addressing the potential of current rapid diagnostic systems being developed as point-of-care (POC) diagnostic tools and the challenges to adapt them at the POC level. Overall, this review provides an insight into the current status of rapid and POC diagnostic systems for AMR.

RESUMEN

BACKGROUND & OBJECTIVE: Indians have decreased insulin sensitivity (IS) and a greater adiposity at a lower body mass index (BMI) when compared with other ethnic groups. Despite this, IS has not been studied in Indians of low BMI. This study thus used the hyperinsulinaemic euglycaemic clamp (HEC) technique to compare IS in young normal weight (NW) and low BMI (LBMI) Indian males. Clamp IS was also compared with convenient indices of insulin sensitivity such as the homeostatic model assessment (HOMA). In the NW group, clamp IS was compared with published data of similarly measured IS in other studies and ethnic groups. METHODS: Ten NW [body mass index (BMI): 18.5-25 kg/m(2)] and ten LBMI (BMI < 18.5 kg/m(2)) young healthy Indian males aged between 19-32 yr were recruited through advertisements from Bangalore slums. Fasting plasma glucose and insulin, glucose disposal rates (GDR) and IS were the parameters measured during the HEC technique. RESULTS: The NW group had a Clamp IS of 4.5 (3.8, 5.3) (median, lower, upper quartile, mg/(kg x min)/microU/ml) that was close to half that of the LBMI group; 9.9 (7.1, 13.4: P<0.001). Clamp IS in the NW group was significantly lower than that observed in published studies involving other ethnic groups (P<0.05). Clamp IS and per cent body fat (% BF), were significantly and negatively correlated (n = 20, rho = -0.7, P<0.001). Correlations between Clamp IS and other IS indices ranged from rho = -0.5 for HOMA2-%B to rho = 0.5 for HOMA2-%S (P<0.05); however, the correlation with HOMA1-IR was not significant (rho = 0.4). INTERPRETATION & CONCLUSION: The significantly lower Clamp IS of the NW group compared with the LBMI group and other ethnic groups indicated that IS was impaired in Indians at relatively low BMIs. Most of the convenient indices of IS were significantly correlated with Clamp IS, however, the Clamp IS was more sensitive method with greater discriminatory power, since IS differences between LBMI and NW groups were only apparent with Clamp IS.

RESUMEN

BACKGROUND: Inflammation is a key component of immune response to infections and pathogenesis of metabolic and cardiovascular diseases. Inflammatory biomarkers, including alpha-1-acid glycoprotein (AGP), are considered prognostic tools for predicting risk, monitoring response to therapy, and adjusting nutritional biomarkers for accurate interpretation. Serum is considered a primary source of biomarkers; urine and saliva are increasingly being explored and utilized as rapidly accessible, noninvasive biofluids requiring minimal sample processing and posing fewer biohazard risks. METHODS: A lateral flow immunoassay was developed for an established mobile-based platform to quantify AGP in human serum, urine, and saliva. Assay performance was assessed with purified AGP in buffer, diluted human serum samples (n = 16) banked from a trial in people living with HIV, and saliva and urine (n = 15 each) from healthy participants. Reference methods were conventional clinical chemistry analyzer or commercial ELISA. Bootstrap analysis was used to train and validate sample calibration. FINDINGS: The correlation between the assay and reference method for serum was 0.97 (P < 0.001). Mean (95% CI) best fit line slope was 1.0 (0.88, 1.15) and intercept was -0.003 (-0.08, 0.09). The correlation for urine was 0.93, and for saliva was 0.97 (both P < 0.001). The median CV for the LFIA for AGP in buffer was 13.2% and for all samples was 28.7%. INTERPRETATION: The performance of the assay indicated potential use as a rapid, low sample volume input, and easy method to quantify AGP that can be licensed and adopted by commercial manufacturers for regulatory approvals and production. This has future applications for determining inflammatory status either alone or in conjunction with other inflammatory proteins such as C-reactive protein for prognostic, monitoring, or nutritional status applications, including large-scale country level surveys conducted by the DHS and those recommended by the WHO.

RESUMEN

Following the Fogarty International Center-supported "Mentoring the Mentors" workshops in South America, Africa, and Asia, approaches and guidelines for mentorship at institutions within these low- and middle-income country (LMIC) contexts, appropriate for the respective regional resources and culture, were implemented. Through the presentation of case studies from these three geographic regions, this article illustrates the institutional mentorship infrastructure before the workshop and the identified gaps used to implement strategies to build mentorship capacity at the Universidad Peruana Cayetano Heredia (Peru), Kenya Medical Research Institute (Kenya), Saint John's Research Institute (India), and Eduardo Mondlane University (Mozambique). These case studies illustrate three findings: first, that mentorship programs in LMICs have made uneven progress, and institutions with existing programs have exhibited greater advancement to their mentoring capacity than institutions without formal programs before the workshops. Second, mentoring needs assessments help garner the support of institutional leadership and create local ownership. Third, developing a culture of mentorship that includes group mentoring activities at LMIC institutions can help overcome the shortage of trained mentors. Regardless of the stage of mentoring programs, LMIC institutions can work toward developing sustainable, culturally effective mentorship models that further the partnership of early career scientists and global health.

RESUMEN

A growing body of evidence highlights the importance of competent mentoring in academic research. We describe the development, implementation, and evaluation of four regional 2-day intensive workshops to train mid- and senior-level investigators conducting public health, clinical, and basic science research across multiple academic institutions in low- and middle-income countries (LMICs) on tools and techniques of effective mentoring. Sponsored by the Fogarty International Center, workshops included didactic presentations, interactive discussions, and small-group problem-based learning and were conducted in Lima, Peru; Mombasa, Kenya; Bangalore, India; and Johannesburg, South Africa, from 2013 to 2016. Mid- or senior-level faculty from multiple academic institutions within each region applied and were selected. Thirty faculty from 12 South America-based institutions, 29 faculty from eight East Africa-based institutions, 37 faculty from 14 South Asia-based institutions, and 36 faculty from 13 Africa-based institutions participated, with diverse representation across disciplines, gender, and academic rank. Discussions and evaluations revealed important comparisons and contrasts in the practice of mentoring, and specific barriers and facilitators to mentoring within each cultural and regional context. Specific regional issues related to hierarchy, the post-colonial legacy, and diversity arose as challenges to mentoring in different parts of the world. Common barriers included a lack of a culture of mentoring, time constraints, lack of formal training, and a lack of recognition for mentoring. These workshops provided valuable training, were among the first of their kind, were well-attended, rated highly, and provided concepts and a structure for the development and strengthening of formal mentoring programs across LMIC institutions.

RESUMEN

A growing number of low- and middle-income country (LMIC) institutions have developed and implemented formal programs to support mentorship. Although the individual-level benefits of mentorship are well established, such activities can also sustainably build institutional capacity, bridge inequities in health care, and catalyze scientific advancement. To date, however, evaluation of these programs remains limited, representing an important gap in our understanding about the impact of mentoring. Without rigorous and ongoing evaluation, there may be missed opportunities for identifying best practices, iteratively improving program activities, and demonstrating the returns on investment in mentorship. In this report, we propose a framework for evaluating mentorship programs in LMIC settings where resources may be constrained. We identify six domains: 1) mentor-mentee relationship, 2) career guidance, 3) academic productivity, 4) networking, 5) wellness, and 6) organizational capacity. Within each, we describe specific metrics and how they may be considered as part of evaluation plans. We emphasize the role of measurement and evaluation at the institutional level, so that programs may enhance their mentoring capacity and optimize the management of their resources. Although we advocate for a comprehensive approach to evaluation, we recognize that-depending on stage and relative maturity-some domains may be prioritized to address short- and medium-term program goals.
