Experiences of conditional and unconditional cash transfers intended for improving health outcomes and health service use: a qualitative evidence synthesis.

BACKGROUND: It is well known that poverty is associated with ill health and that ill health can result in direct and indirect costs that can perpetuate poverty. Social protection, which includes policies and programmes intended to prevent and reduce poverty in times of ill health, could be one way to break this vicious cycle. Social protection, particularly cash transfers, also has the potential to promote healthier behaviours, including healthcare seeking. Although social protection, particularly conditional and unconditional cash transfers, has been widely studied, it is not well known how recipients experience social protection interventions, and what unintended effects such interventions can cause.   OBJECTIVES: The aim of this review was to explore how conditional and unconditional cash transfer social protection interventions with a health outcome are experienced and perceived by their recipients.  SEARCH METHODS: We searched Epistemonikos, MEDLINE, CINAHL, Social Services Abstracts, Global Index Medicus, Scopus, AnthroSource and EconLit from the start of the database to 5 June 2020. We combined this with reference checking, citation searching, grey literature and contact with authors to identify additional studies. We reran all strategies in July 2022, and the new studies are awaiting classification. SELECTION CRITERIA: We included primary studies, using qualitative methods or mixed-methods studies with qualitative research reporting on recipients' experiences of cash transfer interventions where health outcomes were evaluated. Recipients could be adult patients of healthcare services, the general adult population as recipients of cash targeted at themselves or directed at children. Studies could be evaluated on any mental or physical health condition or cash transfer mechanism. Studies could come from any country and be in any language. Two authors independently selected studies.  DATA COLLECTION AND ANALYSIS: We used a multi-step purposive sampling framework for selecting studies, starting with geographical representation, followed by health condition, and richness of data. Key data were extracted by the authors into Excel. Methodological limitations were assessed independently using the Critical Appraisal Skills Programme (CASP) criteria by two authors. Data were synthesised using meta-ethnography, and confidence in findings was assessed using the Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) approach.  MAIN RESULTS: We included 127 studies in the review and sampled 41 of these studies for our analysis. Thirty-two further studies were found after the updated search on 5 July 2022 and are awaiting classification. The sampled studies were from 24 different countries: 17 studies were from the African region, seven were from the region of the Americas, seven were from the European region, six were from the South-East Asian region, three from the Western Pacific region and one study was multiregional, covering both the African and the Eastern Mediterranean regions. These studies primarily explored the views and experiences of cash transfer recipients with different health conditions, such as infectious diseases, disabilities and long-term illnesses, sexual and reproductive health, and maternal and child health. Our GRADE-CERQual assessment indicated we had mainly moderate- and high-confidence findings. We found that recipients perceived the cash transfers as necessary and helpful for immediate needs and, in some cases, helpful for longer-term benefits. However, across conditional and unconditional programmes, recipients often felt that the amount given was too little in relation to their total needs. They also felt that the cash alone was not enough to change their behaviour and, to change behaviour, additional types of support would be required. The cash transfer was reported to have important effects on empowerment, autonomy and agency, but also in some settings, recipients experienced pressure from family or programme staff on cash usage. The cash transfer was reported to improve social cohesion and reduce intrahousehold tension. However, in settings where some received the cash and others did not, the lack of an equal approach caused tension, suspicion and conflict. Recipients also reported stigma in terms of cash transfer programme assessment processes and eligibility, as well as inappropriate eligibility processes. Across settings, recipients experienced barriers in accessing the cash transfer programme, and some refused or were hesitant to receive the cash. Some recipients found cash transfer programmes more acceptable when they agreed with the programme's goals and processes.   AUTHORS' CONCLUSIONS: Our findings highlight the impact of the sociocultural context on the functioning and interaction between the individual, family and cash transfer programmes. Even where the goals of a cash transfer programme are explicitly health-related, the outcomes may be far broader than health alone and may include, for example, reduced stigma, empowerment and increased agency of the individual. When measuring programme outcomes, therefore, these broader impacts could be considered for understanding the health and well-being benefits of cash transfers.

A screening tool for psychological difficulties in children aged 6 to 36 months: cross-cultural validation in Kenya, Cambodia and Uganda.

BACKGROUND: In low-resource settings, the lack of mental health professionals and cross-culturally validated screening instruments complicates mental health care delivery. This is especially the case for very young children. Here, we aimed to develop and cross-culturally validate a simple and rapid tool, the PSYCa 6-36, that can be administered by non-professionals to screen for psychological difficulties among children aged six to 36 months. METHODS: A primary validation of the PSYCa 6-36 was conducted in Kenya (n = 319 children aged 6 to 36 months; 2014), followed by additional validations in Kenya (n = 215; 2014) Cambodia (n = 189; 2015) and Uganda (n = 182; 2016). After informed consent, trained interviewers administered the PSYCa 6-36 to caregivers participating in the study. We assessed the psychometric properties of the PSYCa 6-36 and external validity was assessed by comparing the results of the PSYCa 6-36 against a clinical global impression severity [CGIS] score rated by an independent psychologist after a structured clinical interview with each participant. RESULTS: The PSYCa 6-36 showed satisfactory psychometric properties (Cronbach's alpha > 0.60 in Uganda and > 0.70 in Kenya and Cambodia), temporal stability (intra-class correlation coefficient [ICC] > 0.8), and inter-rater reliability (ICC from 0.6 in Uganda to 0.8 in Kenya). Psychologists identified psychological difficulties (CGIS score > 1) in 11 children (5.1%) in Kenya, 13 children (8.7%) in Cambodia and 15 (10.5%) in Uganda, with an area under the receiver operating characteristic curve of 0.65 in Uganda and 0.80 in Kenya and Cambodia. CONCLUSIONS: The PSYCa 6-36 allowed for rapid screening of psychological difficulties among children aged 6 to 36 months among the populations studied. Use of the tool also increased awareness of children's psychological difficulties and the importance of early recognition to prevent long-term consequences. The PSYCa 6-36 would benefit from further use and validation studies in popula`tions with higher prevalence of psychological difficulties.

High Proportions of Patients With Advanced HIV Are Antiretroviral Therapy Experienced: Hospitalization Outcomes From 2 Sub-Saharan African Sites.

Background: Human immunodeficiency virus (HIV) remains an important cause of hospitalization and death in low- and middle- income countries. Yet morbidity and in-hospital mortality patterns remain poorly characterized, with prior antiretroviral therapy (ART) exposure and treatment failure status largely unknown. Methods: We studied HIV-infected inpatients aged ≥13 years from cohorts in Kenya and the Democratic Republic of Congo (DRC), assessing clinical and demographic characteristics and hospitalization outcomes. Kenyan inpatients were prospectively enrolled during hospitalization; identical retrospective data were extracted for Congolese patients meeting the study criteria using routine medical information. Results: Among 338 HIV-infected patients in Kenya and 411 in DRC, 83.7% (95% confidence interval [CI], 79.4%-87.3%) and 97.3% (95% CI, 95.2%-98.5%), were admitted with advanced disease (defined as CD4 <200 cells/µL or World Health Organization stage 3/4 illness). Among inpatients with advanced HIV, 35.4% and 21.7% were ART-naive at admission. Patients under care had a median time of 44.1 (interquartile range [IQR], 18.4-90.5) months and 55.9 (IQR, 28.1-99.6) months on treatment; 17.2% (95% CI, 13.5%-21.6%) and 29.6% (95% CI, 25.4%-34.3%) died, 25.9% (95% CI, 16.0%-39.0%) and 22.5% (95% CI, 15.8%-31.0%) of these within 48 hours. Conclusions: Across 2 diverse clinical contexts in sub-Saharan Africa, advanced HIV inpatients were frequently admitted with low CD4 counts, often failing first-line ART. Earlier identification of treatment failure and rapid switching to second-line ART are needed.

Potential impact of multiple interventions on HIV incidence in a hyperendemic region in Western Kenya: a modelling study.

BACKGROUND: Multiple prevention interventions, including early antiretroviral therapy initiation, may reduce HIV incidence in hyperendemic settings. Our aim was to predict the short-term impact of various single and combined interventions on HIV spreading in the adult population of Ndhiwa subcounty (Nyanza Province, Kenya). METHODS: A mathematical model was used with data on adults (15-59 years) from the Ndhiwa HIV Impact in Population Survey to compare the impacts on HIV prevalence, HIV incidence rate, and population viral load suppression of various interventions. These interventions included: improving the cascade of care (use of three guidelines), increasing voluntary medical male circumcision (VMMC), and implementing pre-exposure prophylaxis (PrEP) use among HIV-uninfected women. RESULTS: After four years, improving separately the cascade of care under the WHO 2013 guidelines and under the treat-all strategy would reduce the overall HIV incidence rate by 46 and 58 %, respectively, vs. the baseline rate, and by 35 and 49 %, respectively, vs. the implementation of the current Kenyan guidelines. With conservative and optimistic scenarios, VMMC and PrEP would reduce the HIV incidence rate by 15-25 % and 22-28 % vs. the baseline, respectively. Combining the WHO 2013 guidelines with VMMC would reduce the HIV incidence rate by 35-56 % and combining the treat-all strategy with VMMC would reduce it by 49-65 %. Combining the WHO 2013 guidelines, VMMC, and PrEP would reduce the HIV incidence rate by 46-67 %. CONCLUSIONS: The impacts of the WHO 2013 guidelines and the treat-all strategy were relatively close; their implementation is desirable to reduce HIV spread. Combining several strategies is promising in adult populations of hyperendemic areas but requires regular, reliable, and costly monitoring.

Comparing Catastrophic Costs: Active vs. Passive Tuberculosis Case Finding in Urban Vietnam.

Active case finding (ACF) is a strategy that aims to identify people with tuberculosis (TB) earlier in their disease. This outreach approach may lead to a reduction in catastrophic cost incurrence (costs exceeding 20% of annual household income), a main target of WHO's End TB Strategy. Our study assessed the socio-economic impact of ACF by comparing patient costs in actively and passively detected people with TB. Longitudinal patient cost surveys were prospectively fielded for people with drug-sensitive pulmonary TB, with 105 detected through ACF and 107 passively detected. Data were collected in four Vietnamese cities between October 2020 and March 2022. ACF reduced pre-treatment (USD 10 vs. 101, p < 0.001) and treatment costs (USD 888 vs. 1213, p < 0.001) in TB-affected individuals. Furthermore, it reduced the occurrence of job loss (15.2% vs. 35.5%, p = 0.001) and use of coping strategies (28.6% vs. 45.7%, p = 0.004). However, catastrophic cost incurrence was high at 52.8% and did not differ between cohorts. ACF did not significantly decrease indirect costs, the largest contributor to catastrophic costs. ACF reduces costs but cannot sufficiently reduce the risk of catastrophic costs. As income loss is the largest driver of costs during TB treatment, social protection schemes need to be expanded.

Assessing access barriers to tuberculosis care with the tool to Estimate Patients' Costs: pilot results from two districts in Kenya.

BACKGROUND: The poor face geographical, socio-cultural and health system barriers in accessing tuberculosis care. These may cause delays to timely diagnosis and treatment resulting in more advanced disease and continued transmission of TB. By addressing barriers and reasons for delay, costs incurred by TB patients can be effectively reduced. A Tool to Estimate Patients' Costs has been developed. It can assist TB control programs in assessing such barriers. This study presents the Tool and results of its pilot in Kenya. METHODS: The Tool was adapted to the local setting, translated into Kiswahili and pretested. Nine public health facilities in two districts in Eastern Province were purposively sampled. Responses gathered from TB patients above 15 years of age with at least one month of treatment completed and signed informed consent were double entered and analyzed. Follow-up interviews with key informants on district and national level were conducted to assess the impact of the pilot and to explore potential interventions. RESULTS: A total of 208 patients were interviewed in September 2008. TB patients in both districts have a substantial burden of direct (out of pocket; USD 55.8) and indirect (opportunity; USD 294.2) costs due to TB. Inability to work is a major cause of increased poverty. Results confirm a 'medical poverty trap' situation in the two districts: expenditures increased while incomes decreased. Subsequently, TB treatment services were decentralized to fifteen more facilities and other health programs were approached for nutritional support of TB patients and sputum sample transport. On the national level, a TB and poverty sub-committee was convened to develop a comprehensive pro-poor approach. CONCLUSIONS: The Tool to Estimate Patients' Costs proved to be a valuable instrument to assess the costs incurred by TB patients, socioeconomic situations, health-seeking behavior patterns, concurrent illnesses such as HIV, and social and gender-related impacts. The Tool helps to identify and tackle bottlenecks in access to TB care, especially for the poor. Reducing delays in diagnosis, decentralization of services, fully integrated TB/HIV care and expansion of health insurance coverage would alleviate patients' economic constraints due to TB.

Determinants of household catastrophic costs for drug sensitive tuberculosis patients in Kenya.

BACKGROUND: Despite free diagnosis and treatment for tuberculosis (TB), the costs during treatment impose a significant financial burden on patients and their households. The study sought to identify the determinants for catastrophic costs among patients with drug-sensitive TB (DSTB) and their households in Kenya. METHODS: The data was collected during the 2017 Kenya national patient cost survey from a nationally representative sample (n = 1071). Treatment related costs and productivity losses were estimated. Total costs exceeding 20% of household income were defined as catastrophic and used as the outcome. Multivariable Poisson regression analysis was performed to measure the association between selected individual, household and disease characteristics and occurrence of catastrophic costs. A deterministic sensitivity analysis was carried using different thresholds and the significant predictors were explored. RESULTS: The proportion of catastrophic costs among DSTB patients was 27% (n = 294). Patients with catastrophic costs had higher median productivity losses, 39 h [interquartile range (IQR): 20-104], and total median costs of USD 567 (IQR: 299-1144). The incidence of catastrophic costs had a dose response with household expenditure. The poorest quintile was 6.2 times [95% confidence intervals (CI): 4.0-9.7] more likely to incur catastrophic costs compared to the richest. The prevalence of catastrophic costs decreased with increasing household expenditure quintiles (proportion of catastrophic costs: 59.7%, 32.9%, 23.6%, 15.9%, and 9.5%) from the lowest quintile (Q1) to the highest quintile (Q5). Other determinants included hospitalization: prevalence ratio (PR) = 2.8 (95% CI: 1.8-4.5) and delayed treatment: PR = 1.5 (95% CI: 1.3-1.7). Protective factors included receiving care at a public health facility: PR = 0.8 (95% CI: 0.6-1.0), and a higher body mass index (BMI): PR = 0.97 (95% CI: 0.96-0.98). Pre TB expenditure, hospitalization and BMI were significant predictors in all sensitivity analysis scenarios. CONCLUSIONS: There are significant inequities in the occurrence of catastrophic costs. Social protection interventions in addition to existing medical and public health interventions are important to implement for patients most at risk of incurring catastrophic costs.

Incremental Yield of Including Determine-TB LAM Assay in Diagnostic Algorithms for Hospitalized and Ambulatory HIV-Positive Patients in Kenya.

BACKGROUND: Determine-TB LAM assay is a urine point-of-care test useful for TB diagnosis in HIV-positive patients. We assessed the incremental diagnostic yield of adding LAM to algorithms based on clinical signs, sputum smear-microscopy, chest X-ray and Xpert MTB/RIF in HIV-positive patients with symptoms of pulmonary TB (PTB). METHODS: Prospective observational cohort of ambulatory (either severely ill or CD4<200cells/µl or with Body Mass Index<17Kg/m2) and hospitalized symptomatic HIV-positive adults in Kenya. Incremental diagnostic yield of adding LAM was the difference in the proportion of confirmed TB patients (positive Xpert or MTB culture) diagnosed by the algorithm with LAM compared to the algorithm without LAM. The multivariable mortality model was adjusted for age, sex, clinical severity, BMI, CD4, ART initiation, LAM result and TB confirmation. RESULTS: Among 474 patients included, 44.1% were severely ill, 69.6% had CD4<200cells/µl, 59.9% had initiated ART, 23.2% could not produce sputum. LAM, smear-microscopy, Xpert and culture in sputum were positive in 39.0% (185/474), 21.6% (76/352), 29.1% (102/350) and 39.7% (92/232) of the patients tested, respectively. Of 156 patients with confirmed TB, 65.4% were LAM positive. Of those classified as non-TB, 84.0% were LAM negative. Adding LAM increased the diagnostic yield of the algorithms by 36.6%, from 47.4% (95%CI:39.4-55.6) to 84.0% (95%CI:77.3-89.4%), when using clinical signs and X-ray; by 19.9%, from 62.2% (95%CI:54.1-69.8) to 82.1% (95%CI:75.1-87.7), when using clinical signs and microscopy; and by 13.4%, from 74.4% (95%CI:66.8-81.0) to 87.8% (95%CI:81.6-92.5), when using clinical signs and Xpert. LAM positive patients had an increased risk of 2-months mortality (aOR:2.7; 95%CI:1.5-4.9). CONCLUSION: LAM should be included in TB diagnostic algorithms in parallel to microscopy or Xpert request for HIV-positive patients either ambulatory (severely ill or CD4<200cells/µl) or hospitalized. LAM allows same day treatment initiation in patients at higher risk of death and in those not able to produce sputum.

Estimation and Short-Term Prediction of the Course of the HIV Epidemic Using Demographic and Health Survey Methodology-Like Data.

BACKGROUND: Mathematical models have played important roles in the understanding of epidemics and in the study of the impacts of various behavioral or medical measures. However, modeling accurately the future spread of an epidemic requires context-specific parameters that are difficult to estimate because of lack of data. Our objective is to propose a methodology to estimate context-specific parameters using Demographic and Health Survey (DHS)-like data that can be used in mathematical modeling of short-term HIV spreading. METHODS AND FINDINGS: The model splits the population according to sex, age, HIV status, and antiretroviral treatment status. To estimate context-specific parameters, we used individuals' histories included in DHS-like data and a statistical analysis that used decomposition of the Poisson likelihood. To predict the course of the HIV epidemic, sex- and age-specific differential equations were used. This approach was applied to recent data from Kenya. The approach allowed the estimation of several key epidemiological parameters. Women had a higher infection rate than men and the highest infection rate in the youngest age groups (15-24 and 25-34 years) whereas men had the highest infection rate in age group 25-34 years. The immunosuppression rates were similar between age groups. The treatment rate was the highest in age group 35-59 years in both sexes. The results showed that, within the 15-24 year age group, increasing male circumcision coverage and antiretroviral therapy coverage at CD4 ≤ 350/mm3 over the current 70% could have short-term impacts. CONCLUSIONS: The study succeeded in estimating the model parameters using DHS-like data rather than literature data. The analysis provides a framework for using the same data for estimation and prediction, which can improve the validity of context-specific predictions and help designing HIV prevention campaigns.

Cascade of HIV care and population viral suppression in a high-burden region of Kenya.

INTRODUCTION: Direct measurement of antiretroviral treatment (ART) program indicators essential for evidence-based planning and evaluation - especially HIV incidence, population viral load, and ART eligibility - is rare in sub-Saharan Africa. DESIGN/METHODS: To measure key indicators in rural western Kenya, an area with high HIV burden, we conducted a population survey in September to November 2012 via multistage cluster sampling, recruiting everyone aged 15-59 years living in 3330 randomly selected households. Consenting individuals were interviewed and tested for HIV at home. Participants testing positive were assessed for CD4 cell count and viral load, and their infections classified as either recent or long term based on Limiting Antigen Avidity assays. HIV-negative participants were tested by nucleic acid amplification to detect acute infections. RESULTS: Of 6833 household members eligible for the study, 6076 (94.7% of all women and 81.0% of men) agreed to participate. HIV prevalence and incidence were 24.1% [95% confidence interval [CI] 23.0-25.2] and 1.9 new cases/100 person-years (95% CI 1.1-2.7), respectively. Among HIV-positive participants, 59.4% (95% CI 56.8-61.9) were previously diagnosed, 53.1% (95% CI 50.5-55.7) were receiving care, and 39.7% (95% CI 37.1-42.4) had viral load less than 1000 copies/ml. Applying 2013 WHO recommendations for ART initiation increased the proportion of ART-eligible people from 60.0% (based on national guidelines in place during the survey; 95% CI 57.3-62.7) to 82.0% (95% CI 79.5-84.5). Among HIV-positive people not receiving ART, viral load increased with decreasing CD4 cell count (500-749 vs. ≥750 cells/µl, adjusted mean difference, 0.40 log10 copies/ml, 95% CI 0.20-0.60, P < 0.01). CONCLUSION: This study demonstrates how population-level data can help optimize HIV programs. Based on these results, new regional programs are prioritizing diagnosis and expanding ART eligibility, key steps to reach undetectable viral load.

Screening for psychological difficulties in young children in crisis: complementary cross-cultural validation.

BACKGROUND: Detection of children's psychological difficulties in crises and low resource settings is challenged by the lack of a validated, rapid and simple tool. We present the results of two confirmatory validations of the Psychological Screening for Young Children aged 3 to 6 years (PSYCa 3-6) scale. METHODS: We performed cross-cultural validations, assessing the performance of the scale in different contexts. These were conducted in Mathare, Nairobi, Kenya and Buenaventura, Colombia between December 2009 and February 2012. External validity was assessed comparing the PSYCa 3-6 against a clinical interview and the Clinical Global Impression Severity scale (CGI). RESULTS: A total of 160 mothers or caregivers of children 3 to 6 years old in Mathare and 148 in Buenaventura were included in the study. Both demonstrated good concurrent validity (Buenaventura ρ=0.49, p<0.0001; Mathare ρ=0.41, p<0.0001). Inter-rater reliability was found to be acceptable in Buenaventura (intraclass correlation [ICC]=0.69 [0.4-0.84]) and high in Mathare (0.87 [0.75-0.94]). CONCLUSIONS: As shown by its validation in diverse contexts, use in other populations may help improve the delivery of mental health care to children in crises and low-resource settings. Additional research on the design and delivery of intervention models for crises remains essential.
