SummaryBackgroundHistorically, health facilities in sub-Saharan Africa have mainly managed acute, infectious diseases. Few data exist for the preparedness of African health facilities to handle the growing epidemic of chronic, non-communicable diseases (NCDs). We assessed the burden of NCDs in health facilities in northwestern Tanzania and investigated the strengths of the health system and areas for improvement with regard to primary care management of selected NCDs.MethodsBetween November, 2012, and May, 2013, we undertook a cross-sectional survey of a representative sample of 24 public and not-for-profit health facilities in urban and rural Tanzania (four hospitals, eight health centres, and 12 dispensaries). We did structured interviews of facility managers, inspected resources, and administered self-completed questionnaires to 335 health-care workers. We focused on hypertension, diabetes, and HIV (for comparison). Our key study outcomes related to service provision, availability of guidelines and supplies, management and training systems, and preparedness of human resources.FindingsOf adult outpatient visits to hospitals, 58% were for chronic diseases compared with 20% at health centres, and 13% at dispensaries. In many facilities, guidelines, diagnostic equipment, and first-line drug therapy for the primary care of NCDs were inadequate, and management, training, and reporting systems were weak. Services for HIV accounted for most chronic disease visits and seemed stronger than did services for NCDs. Ten (42%) facilities had guidelines for HIV whereas three (13%) facilities did for NCDs. 261 (78%) health workers showed fair knowledge of HIV, whereas 198 (59%) did for hypertension and 187 (56%) did for diabetes. Generally, health systems were weaker in lower-level facilities. Front-line health-care workers (such as non-medical-doctor clinicians and nurses) did not have knowledge and experience of NCDs. For example, only 74 (49%) of 150 nurses had at least fair knowledge of diabetes care compared with 85 (57%) of 150 for hyptertension and 119 (79%) of 150 for HIV, and only 31 (21%) of 150 had seen more than five patients with diabetes in the past 3 months compared with 50 (33%) of 150 for hypertension and 111 (74%) of 150 for HIV.InterpretationMost outpatient services for NCDs in Tanzania are provided at hospitals, despite present policies stating that health centres and dispensaries should provide such services. We identified crucial weaknesses (and strengths) in health systems that should be considered to improve primary care for NCDs in Africa and identified ways that HIV programmes could serve as a model and structural platform for these improvements.FundingUK Medical Research Council.

BackgroundThe burden of non-communicable diseases (NCDs) is increasing in sub-Saharan Africa, but data available for intervention planning are inadequate. We determined the prevalence of selected NCDs and HIV infection, and NCD risk factors in northwestern Tanzania and southern Uganda.MethodsA population-based cross-sectional survey was conducted, enrolling households using multistage sampling with five strata per country (one municipality, two towns, two rural areas). Consenting adults (≥18 years) were interviewed using the WHO STEPS survey instrument, examined, and tested for HIV and diabetes mellitus (DM). Adjusting for survey design, we estimated population prevalences of hypertension, DM, obstructive pulmonary disease, cardiac failure, epilepsy and HIV, and investigated factors associated with hypertension using logistic regression.ResultsAcross strata, hypertension prevalence ranged from 16 % (95 % confidence interval (CI): 12 % to 22 %) to 17 % (CI: 14 % to 22 %) in Tanzania, and from 19 % (CI: 14 % to 26 %) to 26 % (CI: 23 % to 30 %) in Uganda. It was high in both urban and rural areas, affecting many young participants. The prevalence of DM (1 % to 4 %) and other NCDs was generally low. HIV prevalence ranged from 6 % to 10 % in Tanzania, and 6 % to 12 % in Uganda. Current smoking was reported by 12 % to 23 % of men in different strata, and 1 % to 3 % of women. Problem drinking (defined by Alcohol Use Disorder Identification Test criteria) affected 6 % to 15 % men and 1 % to 6 % women. Up to 46 % of participants were overweight, affecting women more than men and urban more than rural areas. Most patients with hypertension and other NCDs were unaware of their condition, and hypertension in treated patients was mostly uncontrolled. Hypertension was associated with older age, male sex, being divorced/widowed, lower education, higher BMI and, inversely, with smoking.ConclusionsThe high prevalence of NCD risk factors and unrecognized and untreated hypertension represent major problems. The low prevalence of DM and other preventable NCDs provides an opportunity for prevention. HIV prevalence was in line with national data. In Tanzania, Uganda and probably elsewhere in Africa, major efforts are needed to strengthen health services for the PREVENTION, early detection and treatment of chronic diseases.Electronic supplementary materialThe online version of this article (doi:10.1186/s12916-015-0357-9) contains supplementary material, which is available to authorized users.

Background:The Thinking Healthy Programme (THP) is a psychological intervention recommended for the treatment of perinatal depression. We assessed the effectiveness and cost-effectiveness of THP delivered by peers (THPP) in Goa, India. Methods:In this single-blind, individually-randomised controlled trial, we recruited pregnant women aged ≥18 years attending antenatal clinics, who scored ≥10 on the Patient Health Questionnaire (PHQ-9). Participants were randomly allocated (1:1) to THPP plus enhanced usual care (EUC), or to EUC alone in randomly-sized blocks, stratified by area of residence. Allocation was concealed using sequentiallynumbered opaque envelopes. Primary outcomes were severity of depressive symptoms (PHQ-9 score) and remission (PHQ-9 score <5) 6 months post-birth assessed by researchers masked to the treatment allocation. Analyses were by intention to treat, adjusting for covariates defined a priori or that showed imbalance at baseline. The trial is registered with ClinicalTrials.gov (NCT02104232).Findings: 280 women were enrolled between 24th October 2014 and 22nd June 2016 (140 per group). At 6 months, 122 (87%) and 129 (92%) women in the THPP plus EUC, and EUC alone groups, respectively, contributed primary outcome data. There was evidence of higher prevalence of remission at 6 months in the THPP plus EUC versus EUC alone group (n=89 (73%) versus n=77 (60%), respectively; prevalence ratio (PR)=1·21; 95% confidence interval (CI) 1·01 to 1·45, p=0·04), but weaker evidence for lower symptom severity (mean 3·47, standard deviation (SD) 4·49 versus 4·48 (SD=5·11), respectively; standardised mean difference (SMD)=-0·18; 95% CI -0·43 to 0·07, p=0·16).Repeated measures analyses over the duration of the trial (measured at 3 and 6 months post-birth) showed beneficial effects on symptom severity (SMD -0·37, 95% CI -0·88 to -0·24, p=0·01), remission (PR=1·21, 95% CI 1·01 to 1·41, p=0·02), WHO-Disability Assessment Schedule (WHO-DAS) scores (SMD=-0·32, 95% CI -0·76 to -0·21, p=0·02) and Multidimensional Scale of Perceived Social Support (MSPSS) scores (SMD=0·51, 95% CI 0·43 to 1·20, p=0·02). . The incremental societal cost per unit improvement on PHQ-9 was -US$ 29·64 (95% CI-32·88 to -26·41) at 3 months, and -US$93·53 (95% CI -180·21 to -6·84) for the whole duration of the trial, with a 87% likelihood of being costsaving in the study setting. The mean cost of providing THPP was US$ 1·36 per beneficiary (95% CI 1·32 to 1·39). There was no evidence of differences in serious adverse events by group, except stigmatisation was more often reported in the EUC alone (9%) versus the THPP plus EUC group (4%; p=0·08).Interpretation: THPP had a moderate effect on symptom severity and remission from perinatal depression over the 6 month post-natal period. THPP is relatively cheap to deliver and pays for itself through reduced health care, time and productivity costs. Funding: NIMH

Introduction For HIV-positive individuals on antiretroviral therapy (ART), the World Health Organization (WHO) recommends routine viral load (VL) monitoring. We report on the cascade of care in individuals with unsuppressed VL after introduction of routine VL monitoring in a district in Lesotho. Materials and methods In Butha-Buthe district 12 clinics (11 rural, 1 hospital) send samples for VL testing to the district laboratory. We included data from patients aged ≥15 years from Dec 1, 2015 to November 1, 2018. As per WHO guidelines VL <1000 copies/mL are considered suppressed, those ≥1000copies/mL unsuppressed. Patients with unsuppressed VL receive adherence counseling and follow-up VL within 8–12 weeks. Two consecutively unsuppressed VLs should trigger switch to second-line ART. For analysis of the VL monitoring cascade we defined care to be “according to guidelines” if patients with unsuppressed VL received a follow-up VL within <180 days and follow-up VL was either re-suppressed, or again unsuppressed and the individual was switched to second-line within 90 days. Results For 9,949 individuals 24,948 VL tests were available. The majority were female (73%), median age 41 years (interquartile range 33–52), and 58% seen at rural clinics. Overall, 25% (260/1028) of individuals were managed according to guidelines: 40% (410/1028) had a follow-up VL within 180 days of their initial unsuppressed VL and 25% (260/1028) of those either re-suppressed or switched to second-line within 90 days. Female patients were more likely to have a follow-up VL done, (p = 0.015). In rural clinics rates of two consecutively unsuppressed VLs were higher than in the hospital (64% vs. 44%, p<0.001), and rural clinics were less likely to switch these patients to second-line (35% vs. 66%, p<0001). Conclusions Our data show that in a real-life setting availability of routine VL monitoring may not be exploited to its potential. A lack of timely follow-up after a first unsuppressed VL and reluctance to switch patients with confirmed virological failure, reduce the benefit of VL monitoring, i.e. in the rural clinics. Future studies will have to assess models of care which ensure that VL results are met with an action and make use of scalable innovative approaches.

BackgroundCurable, non-viral pathogens account for a significant burden of sexually transmitted infections (STIs), and there is established evidence that STIs increase both HIV acquisition and transmission. We investigated the prevalence, trends, and factors associated with Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and Treponema pallidum, and the performance of syndromic management, among a cohort of women working in bars, hotels, and other food and recreational facilities near large-scale mines in northwestern Tanzania.MethodsHIV-negative women aged 18–44 years (N = 966) were enrolled and followed for 12 months in a microbicides feasibility study. We collected sociodemographic and behavioural data, performed clinical examinations, and tested for STIs, at enrolment and 3-monthly. Risk factors for STIs were investigated using logistic regression models with random effects. Sensitivity, specificity and predictive values of syndromic management were calculated.ResultsAt enrolment, the prevalences of C. trachomatis, N. gonorrhoeae, T. vaginalis, and high-titre active syphilis were 111/956 (12%), 42/955 (4%), 184/945 (19%) and 46/965 (5%), respectively. There were significant decreases over time for C. trachomatis and T. vaginalis (OR trend per month: 0.94 [95% CI 0.91, 0.97]; and 0.95 [0.93, 0.98], respectively; both p<0.001). The majority of these infections were not diagnosed by the corresponding syndrome; therefore, most participants were not treated at the diagnosis visit. Syndromic management was poorly predictive of laboratory-diagnosed infections. We identified a number of risk factors for STIs, including low educational level, some sexual behaviours, and ever having been pregnant.ConclusionsThis analysis demonstrates that the prevalences of curable STIs are high among women who work in food and recreational facilities in northwestern Tanzania. Most of these infections are missed by syndromic management. Accurate and affordable rapid-point-of-care tests and innovative interventions are needed to reduce the burden of STIs in this population which is at increased risk for HIV.
