Contested notions of challenges affecting Community Health Workers in low- and middle-income countries informed by the Silences Framework.

Despite increasing evidence of the challenges affecting Community Health Workers (CHWs) such as those related to training, supportive supervision and remuneration, there is a need to explore concerns and challenges from the perspective of CHWs themselves. This commentary highlights some of the contested and unexplored notions of challenges affecting CHWs in low- and middle-income countries (LMICs) informed by the Silences Framework. This framework defines experiences that are under-explored, misunderstood or difficult to share because of the often invisible power relations within communities, but also in setting the research agenda. These challenges include the heavy workload imposed by several stakeholders, dealing with religious and cultural practices, and gendered barriers of care. The workload of CHWs is a major source of stress and anxiety as they have to balance both government and other stakeholders' agendas to deliver interventions with their own need to provide for their families for those whose work is unpaid. The tensions of CHWs carrying out their work among members of the community whose religious or cultural beliefs are different from theirs also needs to be considered. Gender issues are an impediment to the work of CHWs, particularly with community members of the opposite sex around sensitive health issues. Lastly, CHWs have found themselves victims of domestic suspicion while fulfilling their duties in communities, such as when seen having conversations with spouses of other individuals in the community. Solutions to these challenges need to be co-produced with CHWs to both to strengthen their relationship with the communities they serve and shape more sustainable interventions for delivery of healthcare in LMICs.

Analysing 3429 digital supervisory interactions between Community Health Workers in Uganda and Kenya: the development, testing and validation of an open access predictive machine learning web app.

BACKGROUND: Despite the growth in mobile technologies (mHealth) to support Community Health Worker (CHW) supervision, the nature of mHealth-facilitated supervision remains underexplored. One strategy to support supervision at scale could be artificial intelligence (AI) modalities, including machine learning. We developed an open access, machine learning web application (CHWsupervisor) to predictively code instant messages exchanged between CHWs based on supervisory interaction codes. We document the development and validation of the web app and report its predictive accuracy. METHODS: CHWsupervisor was developed using 2187 instant messages exchanged between CHWs and their supervisors in Uganda. The app was then validated on 1242 instant messages from a separate digital CHW supervisory network in Kenya. All messages from the training and validation data sets were manually coded by two independent human coders. The predictive performance of CHWsupervisor was determined by comparing the primary supervisory codes assigned by the web app, against those assigned by the human coders and calculating observed percentage agreement and Cohen's kappa coefficients. RESULTS: Human inter-coder reliability for the primary supervisory category of messages across the training and validation datasets was 'substantial' to 'almost perfect', as suggested by observed percentage agreements of 88-95% and Cohen's kappa values of 0.7-0.91. In comparison to the human coders, the predictive accuracy of the CHWsupervisor web app was 'moderate', suggested by observed percentage agreements of 73-78% and Cohen's kappa values of 0.51-0.56. CONCLUSIONS: Augmenting human coding is challenging because of the complexity of supervisory exchanges, which often require nuanced interpretation. A realistic understanding of the potential of machine learning approaches should be kept in mind by practitioners, as although they hold promise, supportive supervision still requires a level of human expertise. Scaling-up digital CHW supervision may therefore prove challenging. TRIAL REGISTRATION: This was not a clinical trial and was therefore not registered as such.

Hip and groin pain prevalence and prediction in Elite Gaelic Games: 2703 male athletes across two seasons.

OBJECTIVE: Hip and groin pain is highly prevalent in sub-elite Gaelic Athletic Association (GAA) athletes, but its prevalence at the elite level is unknown. The aims of this study were to report hip and groin pain prevalence in elite male athletes, to report changes in Copenhagen Hip and Groin Outcome Score (HAGOS) across two seasons and to assess if previous hip and groin pain or pre-season HAGOS could predict future hip and groin pain. METHODS: During the 2017 and 2018 pre-season male Gaelic Players Association (GPA) playing members were invited to complete two questionnaires. The first questionnaire collected demographic information including age, GAA code played (Gaelic football or Hurling) and prevalence of hip and groin pain in the previous season. The second questionnaire was the HAGOS. Step-wise logistic regression models were fitted to HAGOS subscales, to examine if pre-season HAGOS subscale scores could predict future hip and groin pain. RESULTS: The prevalence of hip and groin pain across the elite GAA cohort was 38%. Hip and groin pain in the previous season was the strongest predictor of future hip and groin pain (r2 =0.19, AUC=0.73, 95% CI 1.76-2.27) whereas pre-season HAGOS subscale scores had limited and no additional predictive ability (AUC 0.05-0.18). CONCLUSIONS: Hip and groin pain prevalence is high in elite male GAA, with one in three athletes reporting pain. Previous season hip and groin pain is the strongest predictor of future hip and groin pain, while pre-season HAGOS scores have limited ability to predict future hip and groin pain.

Training, supervision and performance of Community Health Workers in the delivery of ear and hearing care to 321 community members in rural Uganda.

OBJECTIVES: Community Health Workers are one way to address the shortage of ear and hearing care specialists in low-resource settings. However, there are few reports evaluating training and service delivery by Community Health Workers. DESIGN, SETTING AND PARTICIPANTS: We trained 13 Community Health Workers in primary ear and hearing care in Mukono District, Uganda. Community Health Workers attended a two-day training workshop and received remote supervision thereafter during service delivery in the community. An ear camp was held at the local health centre every two months, where a local ENT specialist could assess referred cases. MAIN OUTCOME MEASURES: Clinical and diagnostic skills and decision-making were assessed using an Objective Structured Clinical Examination, with scores recorded at baseline and six months. Service delivery was evaluated by analysing the following: (i) number of individuals evaluated; (ii) treatments delivered; (iii) cases referred for specialist opinion; (iv) proportion of appropriately referred cases; and (v) agreement between Community Health Worker and specialist diagnosis. RESULTS: Observed Structured Clinical Examination scores were high and stable for six months. 312 individuals were screened in the community by the Community Health Workers, with 298 classified as having an abnormality. Care was delivered in the community to 167 of these, and the remaining 131 referred to the ear camp. Diagnostic agreement was 39%, but 98% of referrals were deemed "appropriate" by the ENT specialist. 27 individuals self-presented to the ear camp without prior assessment by a Community Health Worker, and 97% of these were deemed appropriate. CONCLUSION: Trained Community Health Workers can play an important role in delivering ear and hearing services. Future work should look to explore this model in other contexts and/or compare it to other models of service delivery.

Exploring perceptions, barriers, and enablers for delivery of primary ear and hearing care by community health workers: a photovoice study in Mukono District, Uganda.

BACKGROUND: Hearing loss is a prevalent but neglected disease, especially in low- or middle-income countries. The role of Community Health Workers (CHWs) to deliver primary ear and hearing care has been explored in several studies from a technical standpoint, but understanding perceptions, barriers, and enablers of such an approach from the perspective of CHWs themselves through a health equity lens has been less well documented. METHODS: This qualitative study used photovoice to explore the views and experiences of CHWs in the Seeta Nazigo Parish of Mukono District in the delivery of ear and hearing care in the community. CHWs were trained in ear and hearing care, and provided with digital cameras to capture photographs related to their work in the community over the following 3 months. Individual interviews regarding the photographs were held at the end of each month, in addition to one focus group discussion. A community workshop was convened at the end of the study to display the photos. Thematic analysis of photographs was conducted using Braune and Clarkes six-step framework. We also used the data to explore potential roles for key stakeholders in primary ear and hearing care, and how photovoice may facilitate their engagement. RESULTS: 13 CHWs participated in the study. Several themes were generated from analysis. CHWs perceived a high burden of ear and hearing disorders in their community and recognised the role they could play in tackling that burden. Potential barriers identified included a lack of equipment, training, and supervision of CHWs; logistical, financial, or psychological barriers to community participation; and the widespread use of traditional medicine. CHWs identified roles for the government and NGO bodies to enable and support delivery of ear and hearing care in the community. The community workshop was a useful method to engage key stakeholders in this topic. CONCLUSIONS: Photovoice is a powerful method to capture issues affecting CHWs. Here it was used to identify a number of perceptions, barriers and enablers to the delivery of ear and hearing care. Our results may inform future strategy in the field of ear and hearing care, and the potential use of photovoice to enact sociocultural change.

Participatory approaches, local stakeholders and cultural relevance facilitate an impactful community-based project in Uganda.

Sanitation is a major global challenge that is often addressed at national and international levels, while community opinions and beliefs are neglected. To promote water, sanitation and hygiene (WASH) we organized a cross-cultural knowledge exchange workshop to assess participatory methods for engaging local stakeholders. The workshop included 22 participants from all sectors of society. Practical solutions to sanitation challenges were identified and later shared with a local community. Qualitative and quantitative analyses were used to assess impact and showed participatory methods were highly valued to encourage information sharing among widely varied stakeholders, and that video was a particularly successful approach when engaging with local communities. An 8-month follow-up survey of village members revealed excellent information recall, positive behaviour changes and a desire for future visits. Our evidence suggests that community-based participation helped identify solutions to WASH issues affecting rural communities in resource-poor settings. Engaging in a multicultural knowledge-share was particularly valuable as it enabled participants to recognize they have common challenges and allowed them to share low-cost solutions from their different communities. Our use of video was widely viewed as an ideal means of circulating findings, as it communicated information to people with a wide variety of community roles and to all age groups. Its relevance was increased by adopting a culturally appropriate context by involving local communities in workshop activities. We recommend that research in low- and middle-income countries should be mindful of the environmental context in which WASH is implemented, and encourage acceptance by engaging with communities through the use of varied participatory methods.

The use of low-cost Android tablets to train community health workers in Mukono, Uganda, in the recognition, treatment and prevention of pneumonia in children under five: a pilot randomised controlled trial.

BACKGROUND: Since 2012, The World Health Organization and UNICEF have advocated for community health workers (CHWs) to be trained in Integrated Community Case Management (iCCM) of common childhood illnesses, such as pneumonia. Despite the effectiveness of iCCM, CHWs face many barriers to accessing training. This pilot study compares traditional training with using locally made videos loaded onto low-cost Android tablets to train CHWs on the pneumonia component of iCCM. METHODS: We conducted a pilot randomised controlled trial with CHWs in the Mukono District of Uganda. The unit of randomisation was the sub-county level, and the unit of analysis was at the level of the individual CHW. Eligible CHWs had completed basic iCCM training but had not received any refresher training on the pneumonia component of iCCM in the preceding 2 years. CHWs in the control group received training in the recognition, treatment, and prevention of pneumonia as it is currently delivered, through a 1-day, in-person workshop. CHWs allocated to the intervention group received training via locally made educational videos hosted on low-cost Android tablets. The primary outcome was change in knowledge acquisition, assessed through a multiple choice questionnaire before and after training, and a post-training clinical assessment. The secondary outcome was a qualitative evaluation of CHW experiences of using the tablet platform. RESULTS: In the study, 129 CHWs were enrolled, 66 and 63 in the control and intervention groups respectively. CHWs in both groups demonstrated an improvement in multiple choice question test scores before and after training; however, there was no statistically significant difference in the improvement between groups (t = 1.15, p = 0.254). There was a statistically significant positive correlation (Pearson's r = 0.26, p = 0.03) linking years of education to improvement in test scores in the control group, which was not present in the intervention group. The majority of CHWs expressed satisfaction with the use of tablets as a training tool; however, some reported technical issues (n = 9). CONCLUSION: Tablet-based training is comparable to traditional training in terms of knowledge acquisition. It also proved to be feasible and a satisfactory means of delivering training to CHWs. Further research is required to understand the impacts of scaling such an intervention. TRIAL REGISTRATION: Registered on 23/11/2016 at clinicaltrials.gov ( NCT02971449 ).

Why do women request an elective cesarean delivery for non-medical reasons? A systematic review of the qualitative literature.

BACKGROUND: Cesarean rates have increased significantly over the past decade. The reasons for this are both complex and context specific, and have significant consequences for health resources. The aim of this systematic review was to assess published, peer-reviewed, and gray qualitative literature on the reasons behind cesarean delivery on maternal request (CDMR). METHODS: A systematic search of MEDLINE, EMBASE, CINAHL, LILACS, and PsycINFO databases was performed for all relevant articles published between January 2006 and June 2016. Reference lists of all included studies were also searched in addition to select web-based sources. Studies were included if they qualitatively evaluated women's preferences for CDMR, with no geographic restriction. Findings from the studies were narratively and thematically synthesized. RESULTS: Sixteen studies were included in this review. Three themes were identified as to why women choose CDMR, which were: social norms, emotional experiences, and personal experiences. A woman's decision was often shaped by various influences including family, friends, and the media. In addition, previous experience of childbirth and interactions with health care professionals contributed to a strong preference for CDMR. CDMR provided women with a sense of control over the birth and diminished feelings of fear. CONCLUSIONS: The reasons behind CDMR are multifactorial and complex. Situation-specific cultural factors, fear of pain during childbirth, previous experience, and interactions with health care professionals are likely to have led to the increase in CDMR. Multifaceted, context-specific approaches are required if there is to be a reduction in CDMR rates.
