Dixon Chibanda: grandmothers help to scale up mental health care.

Dixon Chibanda developed the Friendship Bench approach to mental health care in Zimbabwe. He tells Fiona Fleck how he is taking the innovative approach to other countries

Mental health in Zimbabwe.

Zimbabwe is a landlocked country which has recently emerged from some marked political and socioeconomic challenges. Against this background, mental health has fallen down the priority list, as matters such as food shortages and the AIDS scourge have taken precedence. Zimbabwe is in southern Africa; Zambia and Botswana lie to the north, Namibia to the west, South Africa to the south and Mozambique to the east. Its population is 11.4 million. The capital city is Harare, which has a population of 1.6 million

Validation of the posttraumatic stress disorder checklist - 5 (PCL-5) in a primary care population with high HIV prevalence in Zimbabwe.

BACKGROUND: There is a dearth of validated tools measuring posttraumatic stress disorder (PTSD) in low and middle-income countries in sub-Saharan Africa. We validated the Shona version of the PTSD Checklist for DSM-5 (PCL-5) in a primary health care clinic in Harare, Zimbabwe. METHOD: Adults aged 18 and above attending the clinic were enrolled over a two-week period in June 2016. After obtaining written consent, trained research assistants administered the tool to eligible participants. Study participants were then interviewed independently using the Clinician Administered PTSD Scale (CAPS-5) as the gold standard by one of five doctors with training in mental health. RESULT: A total of 204 participants were assessed. Of these, 91 (44.6%) were HIV positive, 100 (49%) were HIV negative, while 13 (6.4%) did not know their HIV status. PTSD was diagnosed in 40 (19.6%) participants using the gold standard procedure. Using the PCL-5 cut-off of ≥33, sensitivity and specificity were 74.5% (95%CI: 60.4-85.7); 70.6% (95%CI: 62.7-77.7), respectively. The area under the ROC curve was 0.78 (95%CI: 0.72-0.83). The Shona version of the PCL-5 demonstrated good internal consistency (Cronbach's alpha = 0.92). CONCLUSION: The PCL-5 performed well in this population with a high prevalence of HIV. There is need to explore ways of integrating screening tools for PTSD in interventions delivered by lay health workers in low and middle-income countries (LMIC)

Neurocognitive impairment in treatment-experienced adults living with HIV attending primary care clinics in Zimbabwe

Background HIV affects the central nervous system resulting in HIV associated neurocognitive impairment (NCI) in approximately 50% of people living with HIV. It typically affects memory, learning, working memory, fine motor skills, speed of information processing, verbal fluency and executive functioning cognitive domains. NCI can affect adherence to antiretroviral therapy (ART), employability, driving ability and activities of daily living. NCI is not routinely screened for in Zimbabwe, and the burden is not known in this setting. The objectives of this study were: 1) To determine NCI prevalence using a comprehensive neuropsychological battery at two primary health care clinics in Harare; 2) To assess the pattern of cognitive impairment across cognitive domains using a gold standard neuropsychological (NP) battery in HIV-positive patients compared to HIV-negative controls. Methods Inclusion criteria: 18 years or older; minimum 7 years education; no neurological or psychiatric disorders. HIV-positive participants were on ART for ≥3 months; HIV-negative participants had a confirmed HIV negative status in the past month. A comprehensive NP battery, functional assessments, demographic and medical history questionnaires were administered. The NP battery consisted of tests assessing memory, learning, working memory, fine motor skills, speed of information processing, verbal fluency and executive functioning. Results Two-hundred-and-thirty-one participants were recruited. Of those, 155 were HIV-positive (Female = 70%, Age M = 37.8; SD 11.2) and 76 HIV-negative (Female = 63%, Age M = 31.2; SD 9.9). HIV-positive participants were on ART for an average of 6 years. NCI was present in 49.7% HIV positive participants. Compared to HIV-negative participants, the HIV-positive group had significantly poorer scores in 5 out of 7 cognitive domains. A good level of education is negatively correlated with NCI. Conclusions NCI prevalence in HIV-positive population Zimbabwe is consistent with global estimates. NCI persists in adults who are on ART. Routine assessment of NCI in adults attending primary care clinics using this adapted battery is therefore important so that they are identified early and are provided the necessary interventions

Prevalence and correlates of probable common mental disorders in a population with high prevalence of HIV in Zimbabwe

BackgroundIn 2014 close to 10 million people living with HIV (PLWH) in sub-Saharan Africa were on highly active anti-retroviral therapy (HAART). The incidence of non-communicable diseases has increased markedly in PLWH as mortality is reduced due to use of HAART. Common mental disorders (CMD) are highly prevalent in PLWH. We aimed to determine factors associated with probable CMD and depression, assessed by 2 locally validated screening tools in a population with high prevalence of HIV in Harare, Zimbabwe.MethodsWe carried out a cross-sectional survey of a systematic random sample of patients utilizing the largest primary health care facility in Harare. Adults aged ≥18years attending over a 2-week period were eligible, excluding those who were critically ill or unable to give written informed consent. Two locally validated screening tools the Shona symptom questionnaire (SSQ-14) and the Patient Health Questionnaire (PHQ-9) were administered by trained research assistants to identify probable CMD and depression.ResultsOf the 264 participants, 165 (62.5%) were PLWH, and 92% of these were on HAART. The prevalence of probable CMD (SSQ14 > = 9) and depression (PHQ9 > = 11) were higher among people living with HIV than among those without HIV (67.9 and 68.5% vs 51.4 and 47.2% respectively). Multivariable analysis showed female gender and recent negative life events to be associated with probable CMD and depression among PLWH (gender: OR = 2.32 95 % CI:1.07–5.05; negative life events: OR = 4.14; 95 % CI 1.17–14.49) and with depression (gender: OR = 1.84 95 % CI:0.85–4.02; negative life events: OR = 4.93.; 95 % CI 1.31–18.50)ConclusionElevated scores on self-report measures for CMD and depression are highly prevalent in this high HIV prevalence population. There is need to integrate packages of care for CMD and depression in existing primary health care programs for HIV/AIDS

Impact of Friendship Bench problem-solving therapy on adherence to ART in young people living with HIV in Zimbabwe: A qualitative study.

BACKGROUND: Adolescents and young people globally are highly vulnerable to poor mental health especially depression, and they account for 36% of new HIV infections in Eastern and Southern Africa. HIV services remain inadequate for this population and their adherence to ART is low. The Friendship Bench (FB), an evidence-based model developed in Zimbabwe to bridge the mental health gap, is a brief psychological intervention delivered on benches in primary care facilities by lay health workers ("grandmothers") trained in problem-solving therapy. This study explored the experience of young people living with HIV attending FB, and their perception of how problem-solving therapy impacted their adherence to ART. METHODS: Semi-structured interviews were conducted in July 2019 with 10 young people living with HIV aged 18-24 years, who had recently completed FB counselling in Harare. Participants were purposively sampled and recruited from three primary care facilities. Interviews were conducted in Shona, audio-recorded, transcribed verbatim and translated into English. Transcripts were analysed in NVivo12 using inductive thematic analysis. RESULTS: Study findings revealed a clear emotional denial towards HIV, particularly for young people infected perinatally, and a resulting low adherence to ART. The study also unpacked the issues of internal stigma and how young people living with perinatally acquired HIV are informed of their HIV status. Participants reported that FB had a critical role in helping them accept their HIV status. Grandmothers' empathic attitude was key during counselling on adherence to ART, to demystify the disease and treatment, normalize the reality of living with HIV, encourage young people to socialize with peers and free them of guilt. Interviewees unanimously reported improved ART adherence following FB counselling, and many described enhanced health and wellbeing. CONCLUSION: Participants saw FB as a strong contributor to their general well-being, evident in decreased symptoms of depression and improved adherence to ART. FB problem-solving therapy should be rolled out to further support young people after post-test counselling or HIV serostatus disclosure for perinatally acquired HIV, for acceptance of HIV status and adherence to ART

The Friendship Bench programme: a cluster randomised controlled trial of a brief psychological intervention for common mental disorders delivered by lay health workers in Zimbabwe.

BACKGROUND: Common mental disorders (CMD) are a leading cause of disability globally. Emerging evidence indicates that in low and middle income countries the treatment gap for CMD can be addressed through the use of trained and supervised lay health workers (LHWs). Few clinical trials have evaluated the use of such task-shifting approaches in sub-Saharan Africa. In Zimbabwe, we have successfully piloted a task-shifting intervention delivered by LHWs. This protocol describes a cluster randomised controlled trial to assess the effectiveness of this intervention. METHODS: Each of 24 randomly selected clinics from a pool of 42 in Harare will recruit 24 participants (N = 576). The clinics are randomised in a 1:1 ratio to receive either the intervention package [a problem solving therapy package delivered over a 4-6 week period by LHWs (N = 24) followed by a 6-week group support programme which focuses mainly on teaching a craft skill] or enhanced usual care, which includes usual care and psycho-education. Primary care attenders aged 18 years and above who score positive on a locally validated CMD screening questionnaire (Shona Symptom Questionnaire, SSQ-14) will be eligible for recruitment and asked for informed consent to participate in the trial. The primary measure is the SSQ score at 6 months. CONCLUSION: This effectiveness trial using LHWs to address the treatment gap for CMD will contribute to the body of knowledge on the feasibility and ability for scale-up of interventions for CMD.

An Interesting Case of Carbamazepine-Induced Stevens-Johnson Syndrome.

A 29-year-old Black female patient was admitted to a psychiatric ward with symptoms of major depressive disorder with psychosis. The patient was started on amitriptyline 50 mg/day and haloperidol 10 mg/day. On day 4 post-admission, the preferred first-line antidepressant, fluoxetine, became available and the patient was switched from amitriptyline to fluoxetine 20 mg/day. On the same day, the dose of haloperidol was reduced to 5 mg/day. Thirteen days post-initiation of these medications the patient became talkative, associated with emotional lability, an expansive mood, irritability and restlessness. The working diagnosis was changed to bipolar affective disorder in the manic phase. Fluoxetine was discontinued and carbamazepine 600 mg/day was added to the patient's treatment regimen. Her manic symptoms started to resolve; however, 14 days post-initiation of carbamazepine, the patient had a fever; itchy, discharging eyes; respiratory distress; generalised symmetrical erythematosus rash; buccal ulceration; and conjunctival injection with difficulty opening her eyes. Carbamazepine was immediately discontinued and the patient received intravenous fluid resuscitation. The patient recovered considerably after 12 days of symptomatic and supportive management, and was transferred back to the psychiatric ward for the continuation of bipolar disorder management. Lithium therapy was instituted and the patient was subsequently discharged. Using the Algorithm of Drug causality for Epidermal Necrolysis (ALDEN) Stevens-Johnson Syndrome/toxic epidermal necrolysis (SJS/TEN) drug causality scoring system, carbamazepine and fluoxetine were evaluated as 'very probable' and 'possible' causes of SJS, respectively, in this patient. Fluoxetine-induced SJS was considered on account of previous case reports, however no evidence of causality was found in this patient. Consecutive administration with a potential increase in carbamazepine due to inhibition of cytochrome P450 (CYP) 3A4 metabolism by fluoxetine was also not ruled out. A diagnosis of carbamazepine-induced SJS was made and was considered an idiosyncratic adverse drug reaction

Depression among HIV positive pregnant women in Zimbabwe: a primary health care based cross-sectional study.

BACKGROUND: Depression is a common psychiatric disorder that is highly prevalent among people living with HIV (PLWH). Depression is linked to poor adherence to anti-retroviral medication while in the peri-natal period may affect birth outcomes. Intimate partner violence (IPV) has been linked to depression. Little is known about the factors associated with depression in HIV positive pregnant women in Zimbabwe. METHODS: We carried out a cross-sectional study in 4 busy primary care clinics offering antenatal services during the months of June through to September in 2016. Simple random sampling was used to screen HIV positive pregnant women while they waited to be attended to at each clinic. Eligible women who gave written informed consent were screened using a locally validated screening tool-the Edinburgh Postnatal Depression Scale (EPDS). RESULTS: A total of 198(85%) participants were recruited out of 234 that were approached. The mean age of participants was 26.6(SD 4.5), of these, 176 (88.9%) had secondary education or more. A total of 78 (39.4%) (95% CI 32.5-46.3) met criteria for antenatal depression according to the local version of the EPDS. Factors associated with antenatal depression after multivariate analysis were intimate partner violence (IPV) [OR 3.2 (95% CI 1.5-6.7)] and previous history of depression OR 4.1 (95% CI 2.0-8.0)]. CONCLUSION: The prevalence of antenatal depression among HIV positive pregnant women in primary care clinics is high. Factors associated with antenatal depression in pregnant HIV positive women are IPV and previous history of depression. There is need for routine screening for depression during the antenatal period and interventions targeting depression in this population should include components to address IPV

Friendship Bench trial: lay worker training in problem-solving therapy to reduce symptoms of common mental disorders

The Friendship Bench trial is a cluster-randomised trial of the effect of problem-solving therapy training for lay workers on symptoms of common mental disorders among clinic attenders in Harare, Zimbabwe. This dataset enables replication of analysis for a paper on suicidal ideation, but has undergone anonymisation process to protect study participants. 12 primary care clinics in Harare were randomised 1:1 to intervention or control. In each clinic, 24 participants were enrolled who were: visiting the clinic (either for their own health needs or accompanying someone else); aged 18 or over; living locally; and screened positive for common mental disorder symptoms. Outcomes were measured after 6 months. 86% of participants were women, 42% were HIV positive and 91% completed follow-up
