Feasibility of screening for cognitive impairment among older persons and referral by community health workers in Wakiso district, Uganda.

BACKGROUND: In Uganda, cognitive impairment in older persons aged ≥ 60 years is often undiagnosed due to inadequate appreciation of the condition compounded with limitations of trained human resource able to conduct appropriate cognitive evaluations. Use of Community Health Workers (CHWs) especially in hard-to-reach communities can be an important link for older persons to the health facilities where they can receive adequate evaluations and interventions for cognitive challenges. The aim of the study was to assess the feasibility of screening for cognitive impairment among older persons and referral by CHWs in Wakiso district, Uganda. METHODS: This was a sequential explanatory mixed methods study. The CHWs received a one-day training on causes, signs and symptoms, and management of cognitive impairment and screened older persons ≥ 60 years for cognitive impairment using the Alzheimer's Disease scale 8 (AD8). Psychiatric clinical officers (PCOs) administered the AD8 and the Mini Mental State Examination to the older persons after assessment by the CHWs who then referred them for appropriate clinical care. We conducted Kappa statistic for agreement between the CHWs and PCOs and compared raw scores of the CHWs to Experts scores using Bland Altman and pair plots and corresponding analyses. We also conducted focus group discussions for the older persons, caregivers and CHWs. RESULTS: We collected data from 385 older persons. We involved 12 CHWs and 75% were females, majority were married (58.3%) with at least a secondary education (66.7%). There was 96.4% (CI 94.5-98.2%) agreement between PCOs and CHWs in identifying cognitive impairment with the PCOs identifying 54/385 (14.0: 95%CI 10.7-17.9%) older persons compared to 58/385 (15.1: 95%CI 11.6-19.0%) identified by CHWs. Of the 58 identified to have cognitive impairment by the CHWs, 93.1% were referred for care. The average difference between the score of the expert and that of the CHW was - 0.042 with a 95% CI of -1.335 to 1.252. Corresponding Bland Altman and pair plots showed high agreement between the measurements although CHWs scored higher values with increasing scores. CONCLUSION: CHWs can be trained to identify and refer older persons with cognitive impairment in the communities.

Mapping services at two Nairobi County primary health facilities: identifying challenges and opportunities in integrated mental health care as a Universal Health Coverage (UHC) priority.

INTRODUCTION: There is a need to scale-up mental health service provision in primary health care. The current extent of integration of mental health in primary care is pertinent to promoting and augmenting mental health at this level. We describe a facility mapping exercise conducted in two low-income/primary health facilities in Kenya to identify existing barriers and facilitators in the delivery of mental health services in general and specifically for peripartum adolescents in primary health care as well as available service resources, cadres, and developmental partners on the ground. METHOD AND MEASURES: This study utilized a qualitative evidence synthesis through mapping facility-level services and key-stakeholder interviews. Services-related data were collected from two facility in-charges using the Nairobi City County Human Resource Health Strategy record forms. Additionally, we conducted 10 key informant interviews (KIIs) with clinical officers (Clinicians at diploma level), Nurses, Community Health Assistants (CHAs), Prevention of Mother-to-child Transmission of HIV Mentor Mothers (PMTCTMs), around both general and adolescent mental health as well as psychosocial services they offered. Using the World Health Organization Assessments Instrument for Mental Health Systems (WHO-AIMS) as a guideline for the interview, all KII questions were structured to identify the extent of mental health integration in primary health care services. Interview transcripts were then systematically analyzed for common themes and discussed by the first three authors to eliminate discrepancies. RESULTS: Our findings show that health care services centered around physical health were offered daily while the mental health services were still vertical, offered weekly through specialist services by the Ministry of Health directly or non-governmental partners. Despite health care workers being aware of the urgent need to integrate mental health services into routine care, they expressed limited knowledge about mental disorders and reported paucity of trained mental health personnel in these sites. Significantly, more funding and resources are needed to provide mental health services, as well as the need for training of general health care providers in the identification and treatment of mental disorders. Our stakeholders underscored the urgency of integrating mental health treatment, prevention, and well-being promotive activities targeting adolescents especially peripartum adolescent girls. CONCLUSION: There is a need for further refining of the integrated care model in mental health services and targeted capacity-building for health care providers to deliver quality services.

The Role of Communities in Mental Health Care in Low- and Middle-Income Countries: A Meta-Review of Components and Competencies.

Community-based mental health services are emphasized in the World Health Organization’s Mental Health Action Plan, the World Bank’s Disease Control Priorities, and the Action Plan of the World Psychiatric Association. There is increasing evidence for effectiveness of mental health interventions delivered by non-specialists in community platforms in low- and middle-income countries (LMIC). However, the role of community components has yet to be summarized. Our objective was to map community interventions in LMIC, identify competencies for community-based providers, and highlight research gaps. Using a review-of-reviews strategy, we identified 23 reviews for the narrative synthesis. Motivations to employ community components included greater accessibility and acceptability compared to healthcare facilities, greater clinical effectiveness through ongoing contact and use of trusted local providers, family involvement, and economic benefits. Locations included homes, schools, and refugee camps, as well as technology-aided delivery. Activities included awareness raising, psychoeducation, skills training, rehabilitation, and psychological treatments. There was substantial variation in the degree to which community components were integrated with primary care services. Addressing gaps in current practice will require assuring collaboration with service users, utilizing implementation science methods, creating tools to facilitate community services and evaluate competencies of providers, and developing standardized reporting for community-based programs.

Contextualization of psychological treatments for government health systems in low-resource settings: group interpersonal psychotherapy for caregivers of children with nodding syndrome in Uganda.

BACKGROUND: Evidence for the effectiveness of psychological treatments in low- and middle-income countries is increasing. However, there is a lack of systematic approaches to guide implementation in government health systems. The objective of this study was to address this gap by employing the Replicating Effective Programs (REP) framework to guide contextualization of a psychological treatment in the Uganda public health system for caregivers of children affected by nodding syndrome, a neuropsychiatric disorder endemic to Sub-Saharan Africa associated with high morbidity and disability. METHODS: To contextualize a psychological treatment, we followed the four components of the REP framework: pre-conditions, pre-implementation, implementation, and maintenance and evolution. A three-step process involved reviewing health services available for nodding syndrome-affected families and current evidence for psychological treatments, qualitative formative research, and analysis and documentation of implementation activities. Stakeholders included members of affected communities, health care workers, therapists, local government leaders, and Ministry of Health officials. Detailed written, audio, and video documentation of the implementation activities was used for content analysis. RESULTS: During the pre-condition component of REP, we selected group interpersonal therapy (IPT-G) because of its feasibility, acceptability, effectiveness in the local setting, and availability of locally developed training materials. During the pre-implementation component, we adapted the training, logistics, and technical assistance strategies in conjunction with government and stakeholder working groups. Adaptations included content modification based on qualitative research with caregivers of children with nodding syndrome. During the implementation component, training was shortened for feasibility with government health workers. Peer-to-peer supervision was selected as a sustainable quality assurance method. IPT-G delivered by community health workers was evaluated for fidelity, patient outcomes, and other process-level variables. More than 90% of beneficiaries completed the treatment program, which was effective in reducing caregiver and child mental health problems. With the Ministry of Health, we conducted preparatory activities for the maintenance and evolution component for scale-up throughout the country. CONCLUSIONS: The REP framework provides a systematic approach to guide contextualization of psychological treatments for delivery in low-resource public health systems. Specific recommendations are provided for REP's application in global mental health. TRIAL REGISTRATION: ISRCTN11382067 ; 08/06/2016; retrospectively registered.

Psychological treatments delivered by community health workers in low-resource government health systems: effectiveness of group interpersonal psychotherapy for caregivers of children affected by nodding syndrome in Uganda.

BACKGROUND: Despite increasing evidence for the benefits of psychological treatments (PTs) in low- and middle-income countries, few national health systems have adopted PTs as standard care. We aimed to evaluate the effectiveness of a group interpersonal psychotherapy (IPT-G) intervention, when delivered by lay community health workers (LCHWs) in a low-resource government health system in Uganda. The intended outcome was reduction of depression among caregivers of children with nodding syndrome, a neuropsychiatric condition with high morbidity, mortality and social stigma. METHODS: A non-randomized trial design was used. Caregivers in six villages (n = 69) received treatment as usual (TAU), according to government guidelines. Caregivers in seven villages (n = 73) received TAU as well as 12 sessions of IPT-G delivered by LCHWs. Primary outcomes were caregiver and child depression assessed at 1 and 6 months post-intervention. RESULTS: Caregivers who received IPT-G had a significantly greater reduction in the risk of depression from baseline to 1 month [risk ratio (RR) 0.25, 95% confidence interval (CI) 0.10-0.62] and 6 months (RR 0.33, 95% CI 0.11-0.95) post-intervention compared with caregivers who received TAU. Children of caregivers who received IPT-G had significantly greater reduction in depression scores than children of TAU caregivers at 1 month (Cohen's d = 0.57, p = 0.01) and 6 months (Cohen's d = 0.54, p = 0.03). Significant effects were also observed for psychological distress, stigma and social support among caregivers. CONCLUSION: IPT-G delivered within a low-resource health system is an effective PT for common mental health problems in caregivers of children with a severe neuropsychiatric condition and has psychological benefits for the children as well. This supports national health policy initiatives to integrate PTs into primary health care services in Uganda.

How competent are non-specialists trained to integrate mental health services in primary care? Global health perspectives from Uganda, Liberia, and Nepal.

Evaluations to objectively assess minimum competency are not routinely implemented for training and supervision in global mental health. Addressing this gap in competency assessment is crucial for safe and effective mental health service integration in primary care. To explore competency, this study describes a training and supervision program for 206 health workers in Uganda, Liberia, and Nepal in humanitarian settings impacted by political violence, Ebola, and natural disasters. Health workers were trained in the World Health Organization's mental health Gap Action Programme (mhGAP). Health workers demonstrated changes in knowledge (mhGAP knowledge, effect size, d = 1.14), stigma (Mental Illness: Clinicians' Attitudes, d = -0.64; Social Distance Scale, d = -0.31), and competence (ENhancing Assessment of Common Therapeutic factors, ENACT, d = 1.68). However, health workers were only competent in 65% of skills. Although the majority were competent in communication skills and empathy, they were not competent in assessing physical and mental health, addressing confidentiality, involving family members in care, and assessing suicide risk. Higher competency was associated with lower stigma (social distance), but competency was not associated with knowledge. To promote competency, this study recommends (1) structured role-plays as a standard evaluation practice; (2) standardized reporting of competency, knowledge, attitudes, and clinical outcomes; and (3) shifting the field toward competency-based approaches to training and supervision.

A Cost-effectiveness Analysis of Antipsychotics for Treatment of Schizophrenia in Uganda.

BACKGROUND: Reductions in prices following the expiry of patents on second-generation antipsychotics means that they could be made available to patients with schizophrenia in low-income countries. In this study we examine the cost effectiveness of antipsychotics for schizophrenia in Uganda. METHODS: We developed a decision-analytic 10-state Markov model to represent the clinical and treatment course of schizophrenia and the experience of the average patient within the Uganda healthcare system. The model was run for a base population of 25-years-old patients attending Butabika National Referral Mental Hospital, in annual cycles over a lifetime horizon. Parameters were derived from a primary chart abstraction study, a local community pharmacy survey, published literature, and expert opinion where necessary. We computed mean disability-adjusted life-years (DALYs) and costs (in US$ 2012) for each antipsychotic, incremental cost, and DALYs averted as well as incremental cost-effectiveness ratios (ICERs). RESULTS: In the base-case analysis, mean DALYs were highest with chlorpromazine (27.608), followed by haloperidol (27.563), while olanzapine (27.552) and risperidone had the lowest DALYs (27.557). Expected costs were highest with quetiapine (US$4943), and lowest with risperidone (US$4424). Compared to chlorpromazine, haloperidol was a dominant option (i.e. it was less costly and more effective); and risperidone was dominant over both haloperidol and quetiapine. The ICER comparing olanzapine to risperidone was US$5868 per DALY averted. CONCLUSION: When choosing between first-generation antipsychotics, clinicians should consider haloperidol as the first-line agent for schizophrenia. However, overall, risperidone is a cost-saving strategy; policymakers should consider its addition to essential medicines lists for treatment of schizophrenia in Uganda.

Patients with nodding syndrome in Uganda improve with symptomatic treatment: a cross-sectional study.

OBJECTIVES: Nodding syndrome (NS) is a poorly understood neurological disorder affecting thousands of children in Africa. In March 2012, we introduced a treatment intervention that aimed to provide symptomatic relief. This intervention included sodium valproate for seizures, management of behaviour and emotional difficulties, nutritional therapy and physical rehabilitation. We assessed the clinical and functional outcomes of this intervention after 12 months of implementation. DESIGN: This was a cross-sectional study of a cohort of patients with NS receiving the specified intervention. We abstracted preintervention features from records and compared these with the current clinical status. We performed similar assessments on a cohort of patients with other convulsive epilepsies (OCE) and compared the outcomes of the two groups. PARTICIPANTS: Participants were patients with WHO-defined NS and patients with OCE attending the same centres. OUTCOME MEASURES: The primary outcome was the proportion of patients with seizure freedom (≥1 month without seizures). Secondary outcome measures included a reduction in seizure frequency, resolution of behaviour and emotional difficulties, and independence in basic self-care. RESULTS: Patients with NS had had a longer duration of symptoms (median 5 (IQR 3, 6) years) compared with those with OCE (4 (IQR 2, 6) years), p<0.001. The intervention resulted in marked improvements in both groups; compared to the preintervention state, 121/484 (25%) patients with NS achieved seizure freedom and there was a >70% reduction in seizure frequency; behaviour and emotional difficulties resolved in 194/327 (59%) patients; 193/484 (40%) patients had enrolled in school including 17.7% who had earlier withdrawn due to severe seizures, and over 80% had achieved independence in basic self-care. These improvements were, however, less than that in patients with OCE of whom 243/476 (51.1%) patients were seizure free and in whom the seizure frequency had reduced by 86%. CONCLUSIONS: Ugandan children with NS show substantial clinical and functional improvements with symptomatic treatments suggesting that NS is probably a reversible encephalopathy.

Cultural concepts of distress and psychiatric disorders: literature review and research recommendations for global mental health epidemiology.

BACKGROUND: Burgeoning global mental health endeavors have renewed debates about cultural applicability of psychiatric categories. This study's goal is to review strengths and limitations of literature comparing psychiatric categories with cultural concepts of distress (CCD) such as cultural syndromes, culture-bound syndromes, and idioms of distress. METHODS: The Systematic Assessment of Quality in Observational Research (SAQOR) was adapted based on cultural psychiatry principles to develop a Cultural Psychiatry Epidemiology version (SAQOR-CPE), which was used to rate quality of quantitative studies comparing CCD and psychiatric categories. A meta-analysis was performed for each psychiatric category. RESULTS: Forty-five studies met inclusion criteria, with 18 782 unique participants. Primary objectives of the studies included comparing CCD and psychiatric disorders (51%), assessing risk factors for CCD (18%) and instrument validation (16%). Only 27% of studies met SAQOR-CPE criteria for medium quality, with the remainder low or very low quality. Only 29% of studies employed representative samples, 53% used validated outcome measures, 44% included function assessments and 44% controlled for confounding. Meta-analyses for anxiety, depression, PTSD and somatization revealed high heterogeneity (I(2) > 75%). Only general psychological distress had low heterogeneity (I(2) = 8%) with a summary effect odds ratio of 5.39 (95% CI 4.71-6.17). Associations between CCD and psychiatric disorders were influenced by methodological issues, such as validation designs (ß = 16.27, 95%CI 12.75-19.79) and use of CCD multi-item checklists (ß = 6.10, 95%CI 1.89-10.31). Higher quality studies demonstrated weaker associations of CCD and psychiatric disorders. CONCLUSIONS: Cultural concepts of distress are not inherently unamenable to epidemiological study. However, poor study quality impedes conceptual advancement and service application. With improved study design and reporting using guidelines such as the SAQOR-CPE, CCD research can enhance detection of mental health problems, reduce cultural biases in diagnostic criteria and increase cultural salience of intervention trial outcomes.
