Effects of a community health worker delivered intervention on maternal depressive symptoms in rural Tanzania

Community-based models of care for adolescent and adult depression, suicidal behavior, anxiety, trauma, and substance use in Africa: a scoping review

Background

Community-based care (CBC), where care is delivered outside of the traditional health facility setting, has been proposed to narrow the mental health (MH) and substance use (SU) treatment gap in Africa.

Objective

This scoping review aims to comprehensively summarize CBC models addressing adolescent and adult MH (depression, anxiety, trauma, suicidal behavior) and (non-tobacco) SU problems in Africa.

Methods

We searched PsycINFO, Embase, Scopus, CINAHL, and Medline Ovid. Studies and protocols were included if they reported on CBC intervention's effects on MH or SU symptoms/ diagnoses, acceptability, feasibility, or patient engagement in care, regardless of whether the intervention itself was designed specifically for MH or SU.

Results

Among 11,477 screened publications, 217 were eligible. Of the unique intervention studies (n = 206), CBC models were classified into the following approaches (non-mutually exclusive): psychotherapeutic (n = 144), social (n = 81), lifestyle/physical health (n = 55), economic (n = 26), and psychopharmacological (n = 2). While quantitative results suggest possible efficacy of CBC models, description of CBC location was often poor. Fewer interventions addressed suicidal behavior (n = 12), the needs of adolescents (n = 49), or used traditional healers or religious figures as providers (n = 3).

Conclusion

Many CBC models have been tested on MH and SU in Africa and should be critically appraised and meta-analyzed in subsequent reviews, where possible.

Perspectives of Pediatric Community Health Workers: Roles, Successes, and Challenges

This multicenter qualitative study described the roles of 10 pediatric community health workers (CHWs) in their own words through exploration of the role features, successes, and challenges in pediatric health care settings across three urban U.S. cities (Philadelphia, New York City, and Cincinnati). Individual, semi-structured telephone interviews were conducted. Interviews described prominent features of the pediatric CHW role, which included taking a family-centered approach to goal setting and determining support needed, ensuring family goals stayed at the center of the work, and acting as a trusted figure for families to talk openly with. CHWs described their role as rewarding, believing in the work, and feeling a sense of fulfillment, and felt successful when families had positive outcomes, including when barriers were eliminated, resources were obtained, or independence was demonstrated by families. Challenges CHWs faced in their roles included establishing trust with families, managing the ever-changing family circumstances many families experience due to socioeconomic barriers, and managing limitations of protocol and restrictions within their roles. This study demonstrated numerous considerations for CHW practice in pediatric health care settings, in addition to considerations for pediatric-specific CHW program development and management. The primary policy implication of this study included a basis for increased funding for CHW programs in pediatric health care settings. This study also demonstrated a need for further research on the change CHWs effect within child and family systems outside of health care, such as schools and child welfare agencies.

Primary-level and community worker interventions for the prevention of mental disorders and the promotion of well-being in low- and middle-income countries

BACKGROUND

There is a significant research gap in the field of universal, selective, and indicated prevention interventions for mental health promotion and the prevention of mental disorders. Barriers to closing the research gap include scarcity of skilled human resources, large inequities in resource distribution and utilization, and stigma.

OBJECTIVES

To assess the effectiveness of delivery by primary workers of interventions for the promotion of mental health and universal prevention, and for the selective and indicated prevention of mental disorders or symptoms of mental illness in low- and middle-income countries (LMICs). To examine the impact of intervention delivery by primary workers on resource use and costs.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, Global Index Medicus, PsycInfo, WHO ICTRP, and ClinicalTrials.gov from inception to 29 November 2021.

SELECTION CRITERIA

Randomized controlled trials (RCTs) of primary-level and/or community health worker interventions for promoting mental health and/or preventing mental disorders versus any control conditions in adults and children in LMICs.

DATA COLLECTION AND ANALYSIS

Standardized mean differences (SMD) or mean differences (MD) were used for continuous outcomes, and risk ratios (RR) for dichotomous data, using a random-effects model. We analyzed data at 0 to 1, 1 to 6, and 7 to 24 months post-intervention. For SMDs, 0.20 to 0.49 represented small, 0.50 to 0.79 moderate, and ≥ 0.80 large clinical effects. We evaluated the risk of bias (RoB) using Cochrane RoB2.

MAIN RESULTS

Description of studies We identified 113 studies with 32,992 participants (97 RCTs, 19,570 participants in meta-analyses) for inclusion. Nineteen RCTs were conducted in low-income countries, 27 in low-middle-income countries, 2 in middle-income countries, 58 in upper-middle-income countries and 7 in mixed settings. Eighty-three RCTs included adults and 30 RCTs included children. Cadres of primary-level workers employed primary care health workers (38 studies), community workers (71 studies), both (2 studies), and not reported (2 studies). Interventions were universal prevention/promotion in 22 studies, selective in 36, and indicated prevention in 55 RCTs. Risk of bias The most common concerns over risk of bias were performance bias, attrition bias, and reporting bias. Intervention effects 'Probably', 'may', or 'uncertain' indicates 'moderate-', 'low-', or 'very low-'certainty evidence. *Certainty of the evidence (using GRADE) was assessed at 0 to 1 month post-intervention as specified in the review protocol. In the abstract, we did not report results for outcomes for which evidence was missing or very uncertain. Adults Promotion/universal prevention, compared to usual care: - probably slightly reduced anxiety symptoms (MD -0.14, 95% confidence interval (CI) -0.27 to -0.01; 1 trial, 158 participants) - may slightly reduce distress/PTSD symptoms (SMD -0.24, 95% CI -0.41 to -0.08; 4 trials, 722 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD -0.69, 95% CI -1.08 to -0.30; 4 trials, 223 participants) Indicated prevention, compared to usual care: - may reduce adverse events (1 trial, 547 participants) - probably slightly reduced functional impairment (SMD -0.12, 95% CI -0.39 to -0.15; 4 trials, 663 participants) Children Promotion/universal prevention, compared to usual care: - may improve the quality of life (SMD -0.25, 95% CI -0.39 to -0.11; 2 trials, 803 participants) - may reduce adverse events (1 trial, 694 participants) - may slightly reduce depressive symptoms (MD -3.04, 95% CI -6 to -0.08; 1 trial, 160 participants) - may slightly reduce anxiety symptoms (MD -2.27, 95% CI -3.13 to -1.41; 1 trial, 183 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD 0, 95% CI -0.16 to -0.15; 2 trials, 638 participants) - may slightly reduce anxiety symptoms (MD 4.50, 95% CI -12.05 to 21.05; 1 trial, 28 participants) - probably slightly reduced distress/PTSD symptoms (MD -2.14, 95% CI -3.77 to -0.51; 1 trial, 159 participants) Indicated prevention, compared to usual care: - decreased slightly functional impairment (SMD -0.29, 95% CI -0.47 to -0.10; 2 trials, 448 participants) - decreased slightly depressive symptoms (SMD -0.18, 95% CI -0.32 to -0.04; 4 trials, 771 participants) - may slightly reduce distress/PTSD symptoms (SMD 0.24, 95% CI -1.28 to 1.76; 2 trials, 448 participants).

AUTHORS' CONCLUSIONS

The evidence indicated that prevention interventions delivered through primary workers - a form of task-shifting - may improve mental health outcomes. Certainty in the evidence was influenced by the risk of bias and by substantial levels of heterogeneity. A supportive network of infrastructure and research would enhance and reinforce this delivery modality across LMICs.

Pathways to scale up early childhood programs: A scoping review of Reach Up and Care for Child Development

Evidence-based early childhood development (ECD) programs that strengthen nurturing parenting skills and promote early stimulation, such as Reach Up (RU) and Care for Child Development (CCD), are critical investments for interrupting cycles of intergenerational poverty; however, the implementation impact of these programs varies greatly globally. Analyzing systematically the evidence on the implementation pathways based on contexts (i.e., external and internal influences on intervention implementation), implementation strategies (i.e., mechanisms used to promote program initiation, design, and delivery with existing systems), and implementation outcomes (i.e., related to the implementation goals) can increase the likelihood of implementation success. Our scoping review aimed to identify implementation pathways of RU and CCD programs in low- and middle-income countries. A search in English, Spanish, and Portuguese of grey literature and five databases of peer reviewed literature; from inception through July 16, 2022, yielded 2,267 publications. Using predetermined eligibility criteria, 75 records yielded implementation details for 33 programs across 23 low- and middle-income countries. Two reviewers independently extracted program data on context, implementation strategies, and implementation outcomes following a program theory. A thematic analysis identified 37 implementation strategies across six "building blocks of implementation": program emergence, intersectoriality, intervention characteristics, workforce, training, and monitoring systems. Implementation pathways across building blocks are highly influenced by contextual factors, such as infrastructure, social norms, and the target population's demand and interest, which may shape different implementation outcomes. Six 'building blocks' shaping implementation pathways of CCD and RU in LMICs were identified. The careful consideration of context and use of intentional evidence-based planning can enable the successful implementation of ECD nurturing care interventions. We recommend the use of the ECD Implementation Checklist for Enabling Program Scale Up to guide decision-making regarding context and implementation strategies to support implementation outcomes and subsequent ECD program success.

Community health workers' perspectives on integrating into school settings to support student health

Introduction

While schools represent key venues for supporting health, they continue to experience gaps in health resources. The integration of community health workers (CHWs) into schools has the potential to supplement these resources but has been underexplored. This study is the first to examine perspectives of experienced CHWs about how CHWs can be applied in school settings to support student health.

Methods

This qualitative study involved conducting semi-structured interviews focused on implementation of CHWs in schools with individuals who held positions aligned with the CHW scope of work. De-identified transcripts were analyzed, and codes were organized into domains and themes.

Results

Among 14 participants, seven domains emerged about the implementation of CHWs in schools: roles and responsibilities, collaborations, steps for integration, characteristics of successful CHWs, training, assessment, and potential challenges. Participants shared various potential responsibilities of school-based CHWs, including educating on health topics, addressing social determinants of health, and supporting chronic disease management. Participants emphasized the importance of CHWs building trusting relationships with the school community and identified internal and external collaborations integral to the success of CHWs. Specifically, participants indicated CHWs and schools should together determine CHWs' responsibilities, familiarize CHWs with the school population, introduce CHWs to the school community, and establish support systems for CHWs. Participants identified key characteristics of school-based CHWs, including having familiarity with the broader community, relevant work experience, essential professional skills, and specific personal qualities. Participants highlighted trainings relevant to school-based CHWs, including CHW core skills and health topics. To assess CHWs' impact, participants proposed utilizing evaluation tools, documenting interactions with students, and observing indicators of success within schools. Participants also identified challenges for school-based CHWs to overcome, including pushback from the school community and difficulties related to the scope of work.

Discussion

This study identified how CHWs can have a valuable role in supporting student health and the findings can help inform models to integrate CHWs to ensure healthy school environments.

Conditional cash transfers to improve health-focused outcomes: a global scoping review

This scoping review assesses the use of conditional cash transfer (CCT) interventions - direct distribution of money to individuals conditional on their compliance to certain requirements - in randomised controlled trials, quasi-experimental studies and large community-based randomised trials with health-focused outcomes. Five databases were searched to identify 68 records published 2004-2021 from 25 countries (8 low- (32%), 5 lower middle- (20%), 6 upper middle- (24%) and 6 high-income (24%), according to the World Bank Categorisation (2017). Forty-six studies were unique (after excluding multiple publications on a single study). The most common outcomes assessed were infectious diseases (30%); maternal health (24%); vaccination rates (17%); and childhood developmental measures (17%). The number of participants receiving CCT in each study ranged from 47 to 5,788, with a median of 487 individuals. The number of total participants ranged from 72 to 14,000, with a median of 1,289 individuals. Fifteen percent of studies involved mobile CCT disbursement. More than a quarter of payments were greater than 50 USD (29%), and most payments were 20 USD or less (58%). Seventy-eight percent of unique full-length studies reported statistically significant CCT effects. Although CCTs remain controversial, a growing evidence base is emerging for their potential impact in specific health conditions.

Patterns and predictors of fear of childbirth and depressive symptoms over time in a cohort of women in the Pwani region, Tanzania

BACKGROUND

Fear of childbirth (FoB) and depressive symptoms (DS) are experienced by many women and can negatively affect women during and after pregnancy. This study assessed patterns of FoB and DS over time and associations of postpartum FoB and DS with sociodemographic and obstetric characteristics.

METHODS

We conducted a longitudinal study at six health facilities in Tanzania in 2018-2019. Pregnant women were consecutively assessed for FoB and DS before and after childbirth using the Wijma Delivery Expectancy/Experience Questionnaire versions A & B and the Edinburgh antenatal and postnatal depressive scale. This paper is based on 625 women who completed participation.

RESULTS

The prevalence rates of FoB and DS during pregnancy were 16% and 18.2%, respectively, and after childbirth, 13.9% and 8.5%. Some had FoB (6.4%) and DS (4.3%) at both timepoints. FoB was strongly associated with DS at both timepoints (p < 0.001). Both FoB (p = 0.246) and DS (p < 0.001) decreased after childbirth. Never having experienced obstetric complications decreased the odds of postpartum and persisting FoB (adjusted odds ratio (aOR) 0.44, 95% confidence interval (CI) 0.23-0.83). Giving birth by caesarean section (aOR 2.01, 95% CI 1.11-3.65) and having more than 12 hours pass between admission and childbirth increased the odds of postpartum FoB (aOR 2.07, 95% CI 1.03-4.16). Postpartum DS was more common in women with an ill child/stillbirth/early neonatal death (aOR 4.78, 95% CI 2.29-9.95). Persisting DS was more common in single (aOR 2.59, 95% CI 1.02-6.59) and women without social support from parents (aOR 0.28, 95% 0.11-0.69).

CONCLUSIONS

FoB and DS coexist and decrease over time. Identifying predictors of both conditions will aid in recognising women at risk and planning for prevention and treatment. Screening for FoB and DS before and after childbirth and offering psychological support should be considered part of routine antenatal and postnatal care. Furthermore, supporting women with previous obstetric complications is crucial. Using interviews instead of a self-administered approach might have contributed to social desirability. Also, excluding women with previous caesarean sections could underestimate FoB and DS prevalence rates.

Stigma of postpartum depression: The role of lady health workers in health care-A qualitative study

The researchers explore the stigma of postpartum depression and role of lady health workers in bringing the women to the health facility and following up on their treatment. In-depth interviews were conducted from the registered patients (n = 22), Lady Health Visitors (n = 2) and Lady Health Workers (LHWs) (n = 2) in a public primary and tertiary healthcare facility in peri-urban areas of district Rawalpindi, Pakistan. Stigma of depression and lack of awareness was perceived as one of the major reasons for women to struggle with the label of postpartum depression and seeking medical treatment. Lady health workers played a significant role in health education and bringing them to the health facility. The services rendered by LHWs can be enhanced through comprehensive training as they can play an effective role in spreading awareness and educating the patients of postpartum depression in peri-urban areas and their families, consequently, ensuring their treatment and its follow-up.
