The Relative Importance and Performance of Key Life Domains on Global Life Satisfaction in Early Adolescents.

OBJECTIVE: This study aimed to investigate the relative importance of key life domains of early adolescents and to explore the heterogeneities across age cohorts and countries at different levels of economic development. METHODS: The repeated cross-sectional survey data for 10 countries (England, Israel, Romania, Norway, Malta, Nepal, Estonia, Ethiopia, South Korea, and Germany) from the second (2013-2014) and third (2016-2019) waves of the International Survey of Children's Well-Being study were used. Early adolescents from the 10- and 12-year age groups were included. A total of 14 key life domains were investigated on their influence to the global life satisfaction. Partial least squares structural equation modeling was used and an importance-performance map analysis was conducted. RESULTS: A total of 23 732 respondents in wave 2 (49% from 10-year-old group) and 22 265 respondents in wave 3 (50% from 10-year-old group) were studied. On average, possessions and safety are the top 2 most important domains within the second wave for 10-year-olds. However, when split based on country-income groups, health comes out on top for low-to-middle-income countries followed by possessions, with safety domain ranking much lower at seventh. For the 12-year-old group, possessions and safety rank highest on average irrespective of the country's level of income. Although areas of priority varied across countries, future came out as one of the most important areas adolescents considered needing improvement across age groups and over time. CONCLUSION: Findings from this study revealed substantial heterogeneity across nations and provide important information for prioritizing policy implementation to improve subjective well-being among early adolescents.

Effectiveness of a telehealth-delivered clinician-supported exercise and weight loss program for hip osteoarthritis - protocol for the Better Hip randomised controlled trial.

BACKGROUND: Hip osteoarthritis (OA) is a leading cause of chronic pain and disability worldwide. Self-management is vital with education, exercise and weight loss core recommended treatments. However, evidence-practice gaps exist, and service models that increase patient accessibility to clinicians who can support lifestyle management are needed. The primary aim of this study is to determine the effectiveness of a telehealth-delivered clinician-supported exercise and weight loss program (Better Hip) on the primary outcomes of hip pain on walking and physical function at 6 months, compared with an information-only control for people with hip OA. METHODS: A two-arm, parallel-design, superiority pragmatic randomised controlled trial. 212 members from a health insurance fund aged 45 years and over, with painful hip OA will be recruited. Participants will be randomly allocated to receive: i) Better Hip; or ii) web-based information only (control). Participants randomised to the Better Hip program will have six videoconferencing physiotherapist consultations for education about OA, prescription of individualised home-based strengthening and physical activity programs, behaviour change support, and facilitation of other self-management strategies. Those with a body mass index > 27 kg/m2, aged < 80 years and no specific health conditions, will also be offered six videoconferencing dietitian consultations to undertake a weight loss program. Participants in the control group will be provided with similar educational information about managing hip OA via a custom website. All participants will be reassessed at 6 and 12 months. Primary outcomes are hip pain on walking and physical function. Secondary outcomes include measures of pain; hip function; weight; health-related quality of life; physical activity levels; global change in hip problem; willingness to undergo hip replacement surgery; rates of hip replacement; and use of oral pain medications. A health economic evaluation at 12 months will be conducted and reported separately. DISCUSSION: Findings will determine whether a telehealth-delivered clinician-supported lifestyle management program including education, exercise/physical activity and, for those with overweight or obesity, weight loss, is more effective than information only in people with hip OA. Results will inform the implementation of such programs to increase access to core recommended treatments. TRIAL REGISTRATION: Australia New Zealand Clinical Trials Registry (ACTRN12622000461796).

Cost-utility analysis of four WHO-recommended sofosbuvir-based regimens for the treatment of chronic hepatitis C in sub-Saharan Africa.

BACKGROUND: Although direct-acting antivirals (DAA) have become standard care for patients with chronic hepatitis C worldwide, there is no evidence for their value for money in sub-Saharan Africa. We assessed the cost-effectiveness of four sofosbuvir-based regimens recommended by the World Health Organization (WHO) in Cameroon, Côte d'Ivoire and Senegal. METHODS: Using modelling, we simulated chronic hepatitis C progression with and without treatment in hypothetical cohorts of patients infected with the country's predominant genotypes (1, 2 and 4) and without other viral coinfections, history of liver complication or hepatocellular carcinoma. Using the status-quo 'no DAA treatment' as a comparator, we assessed four regimens: sofosbuvir-ribavirin, sofosbuvir-ledipasvir (both recommended in WHO 2016 guidelines and assessed in the TAC pilot trial conducted in Cameroon, Côte d'Ivoire and Senegal), sofosbuvir-daclatasvir and sofosbuvir-ledipasvir (two pangenotypic regimens recommended in WHO 2018 guidelines). DAA effectiveness, costs and utilities were mainly estimated using data from the TAC pilot trial. Secondary data from the literature was used to estimate disease progression probabilities with and without treatment. We considered two DAA pricing scenarios: S1) originator prices; S2) generic prices. Uncertainty was addressed using probabilistic and deterministic sensitivity analyses and cost-effectiveness acceptability curves. RESULTS: With slightly higher effectiveness and significantly lower costs, sofosbuvir/velpatasvir was the preferred DAA regimen in S1 with incremental cost-effectiveness ratios (ICERs) ranging from US$526 to US$632/QALY. At the cost-effectiveness threshold (CET) of 0.5 times the 2017 country's per-capita gross domestic product (GDP), sofosbuvir/velpatasvir was only cost-effective in Senegal (probability > 95%). In S2 at generic prices, sofosbuvir/daclatasvir was the preferred regimen due to significantly lower costs. ICERs ranged from US$139 to US$216/QALY according to country i.e. a 95% probability of being cost-effective. Furthermore, this regimen was cost-effective (probability> 95%) for all CET higher than US$281/QALY, US$223/QALY and US$195/QALY in Cameroon, Côte d'Ivoire and Senegal, respectively, corresponding to 0.14 (Côte d'Ivoire and Senegal) and 0.2 (Cameroon) times the country's per-capita GDP. CONCLUSIONS: Generic sofosbuvir/daclatasvir is very cost-effective for treating chronic hepatitis C in sub-Saharan Africa. Large-scale use of generics and an increase in national and international funding for hepatitis C treatment must be priorities for the HCV elimination agenda.

Youth wellbeing through the lens of the Senian capability approach: insights from the occupied Palestinian territory: a cross-sectional study.

BACKGROUND: Interest in the Senian capability framework as an alternative approach to wellbeing measurement has increased in recent decades. The aim of this study was to look at the extent to which an individual's capability to achieve wellbeing in one dimension is associated with his or her attempt to achieve wellbeing in another dimension in a fragile setting affected by conflict. METHODS: Capability is defined as the ability to achieve health, knowledge, and wealth and is measured as latent variables using a structural equation model. Health capability is identified by self-assessed health, mental health, lifestyle, and knowledge of sexually transmitted diseases. Knowledge capability is captured using school attendance, completion of compulsory education, and media access. Wealth capability is identified using indicators on utilities, asset ownership, and housing conditions. Estimation results are used to derive normalised capability scores with values close to 1 indicating high capabilities. A nationally representative sample of 4329 youth aged 15-29 years was drawn from the 2010 Palestinian Family Survey. FINDINGS: Interpretations are made in terms of standardised units, which measure the change in the explained variable due to a standard deviation's change in the explanatory variable. Achieving good health is associated with knowledge capability (0·125; p=0·098) and vice versa (0·462; p=0·004). Health capability is positively associated with wealth capability (0·109; p=0·021); however, the reverse is not the case (-0·753; p=0·021). Men are more likely than women to have higher health knowledge and living conditions capabilities but lower knowledge capabilities. Results suggest the importance of some exogenous factors in the conversion of capabilities into achievements (eg, location of residence). With the exception of health, the data show higher capabilities in Areas A and B of the West Bank than in Area C and the Gaza Strip (mean 0·71 and 0·69 vs 0·60 and 0·61 vs 0·57 and 0·68 for wealth and knowledge, respectively). INTERPRETATION: Although achieving good health appears to entail knowledge capabilities, the wealth-health association is blurred by the effect of exogenous factors (eg, health-care access). Capability deprivation in the local context seems to derive from geographical barriers, as is captured by the contribution of location of residence. This reflects the effect of geopolitical segregation that restricts the movement of people.

HIP fracture Supplemental Therapy to Enhance Recovery (HIPSTER): a protocol for a randomised controlled trial.

INTRODUCTION: Hip fractures result in substantial health impacts for patients and costs to health systems. Many patients require prolonged hospital stays and up to 60% do not regain their prefracture level of mobility within 1 year. Physical rehabilitation plays a key role in regaining physical function and independence; however, there are no recommendations regarding the optimal intensity. This study aims to compare the clinical efficacy and cost-effectiveness of early intensive in-hospital physiotherapy compared with usual care in patients who have had surgery following a hip fracture. METHODS AND ANALYSIS: This two-arm randomised, controlled, assessor-blinded trial will recruit 620 participants who have had surgery following a hip fracture from eight hospitals. Participants will be randomised 1:1 to receive usual care (physiotherapy according to usual practice at the site) or intensive physiotherapy in the hospital over the first 7 days following surgery (two additional sessions per day, one delivered by a physiotherapist and the other by an allied health assistant). The primary outcome is the total hospital length of stay, measured from the date of hospital admission to the date of hospital discharge, including both acute and subacute hospital days. Secondary outcomes are functional mobility, health-related quality of life, concerns about falling, discharge destination, proportion of patients remaining in hospital at 30 days, return to preadmission mobility and residence at 120 days and adverse events. Twelve months of follow-up will capture data on healthcare utilisation. A cost-effectiveness evaluation will be undertaken, and a process evaluation will document barriers and facilitators to implementation. ETHICS AND DISSEMINATION: The Alfred Hospital Ethics Committee has approved this protocol. The trial findings will be published in peer-reviewed journals, submitted for presentation at conferences and disseminated to patients and carers. TRIAL REGISTRATION NUMBER: ACTRN12622001442796.

Implementation of supplemental physiotherapy following hip fracture surgery: a protocol for the process evaluation of a randomised controlled trial.

BACKGROUND: Patient outcomes following low-trauma hip fracture are suboptimal resulting in increased healthcare costs and poor functional outcomes at 1 year. Providing early and intensive in-hospital physiotherapy could help improve patient outcomes and reduce costs following hip fracture surgery. The HIP fracture Supplemental Therapy to Enhance Recovery (HIPSTER) trial will compare usual care physiotherapy to intensive in-hospital physiotherapy for patients following hip fracture surgery. The complex environments in which the intervention is implemented present unique contextual challenges that may impact intervention effectiveness. This study aims to complete a process evaluation to identify barriers and facilitators to implementation and explore the patient, carer and clinician experience of intensive therapy following hip fracture surgery. METHODS AND ANALYSIS: The process evaluation is embedded within a two-arm randomised, controlled, assessor-blinded trial recruiting 620 participants from eight Australian hospitals who have had surgery for a hip fracture sustained via a low-trauma injury. A theory-based mixed method process evaluation will be completed in tandem with the HIPSTER trial. Patient and carer semi-structured interviews will be completed at 6 weeks following hip fracture surgery. The clinician experience will be explored through online surveys completed pre- and post-implementation of intensive therapy and mapped to domains of the Theoretical Domains Framework (TDF). Translation and behaviour change success will be assessed using the Reach Effectiveness-Adoption Implementation Maintenance (RE-AIM) framework and a combination of qualitative and quantitative data collection methods. These data will assist with the development of an Implementation Toolkit aiding future translation into practice. DISCUSSION: The embedded process evaluation will help understand the interplay between the implementation context and the intensive therapy intervention following surgery for low-trauma hip fracture. Understanding these mechanisms, if effective, will assist with transferability into other contexts and wider translation into practice. TRIAL REGISTRATION: ACTRN 12622001442796.

Donor versus recipient preferences for aid allocation: A systematic review of stated-preference studies.

As Official Development Assistance (ODA) tops 180 billion USD per year, there is a need to understand the mechanisms underlying aid effectiveness. Over the past decade we have seen some low- and middle-income countries become developed nations with record economic growth. Others remain in development purgatory, unable to provide their citizens with access to essential services. In an effort to improve aid effectiveness, the prescriptive nature of aid, where (typically) Western countries allocate funds based on perceived need or the strategic priorities of donors is being reconsidered in favour of locally-led development, whereby recipient governments and sometimes citizens are involved in the allocation and delivery of development aid. Meeting the preferences of donors (both governments and citizens) has been a longstanding priority for international development organisations and democratically governed societies. Understanding how these donor preferences relate to recipient preferences is a more recent consideration. This systematic review analysed 58 stated preference studies to summarise the evidence around donor and recipient preferences for aid and, to the extent possible, draw conclusions on where donor and recipient preferences diverge. While the different approaches, methods, and attributes specified by included studies led to difficulties drawing comparisons, we found that donors had a stronger preference than recipients for aid to the health sector, and that aid effectiveness could be more important to donors than recipients when deciding how to allocate aid. Importantly, our review identifies a paucity of literature assessing recipient perspectives for aid using stated preference methods. The dearth of studies conducted from the recipient perspective is perplexing after more than 30 years of 'alignment with recipient preferences', 'local ownership of aid', 'locally-led development' and 'decolonisation of aid'. Our work points to a need for further research describing preferences for aid across a consistent set of attributes in both donor and recipient populations.

A global measure of patient-reported outcomes after injury - life back on track.

PURPOSE: Assess the psychometric properties of the Life Back on Track (LBoT) measure, a novel self-reported single-item global measure of the trajectory of wellbeing after a transport accident. MATERIALS AND METHODS: Evaluated the validity, reliability, sensitivity, and responsiveness using four survey waves (n = 1556 in wave 1), and two repeated cross-sectional surveys (n = 5238) and (n = 1964), of individuals injured in a transport accident in Victoria. RESULTS: There were statistically significant differences in the distribution of the LBoT scores by the respondent depression or pain scores, return to work status, financial ability to get by, ability to cope, and ability to bounce back (all p < 0.001). The LBoT measure was a statistically significant (p < 0.001) and reasonable predictor of future work status, and was moderately correlated (>0.67) with the EQ-5D-3L (concurrent validity). Retest reliability (ICC ≥0.76) and sensitivity (effect sizes >1.52) were supported, and it was moderately responsive to change (standard response mean statistics 0.4-0.8). CONCLUSIONS: LBoT is a valid measure to track the individual's trajectory of subjective wellbeing in the context of recovery after a trauma, and is potentially useful as an indicator to track the performance of commissioned providers, and to monitor or evaluate the value of service outcomes.Implications for RehabilitationThere is a demand to develop a simple metric to measure the impact of injury, the effectiveness of rehabilitation and the degree of recovery from trauma.Life Back on Track (LBoT) is a valid single-item measure to track an individual's trajectory of subjective wellbeing after trauma.It has the potential to complement clinical measures where a routine collection of a simple measure is desirable.It is suitable as an indicator of service outcomes for organisations that commission services.

Cost-effectiveness of screening for primary aldosteronism in hypertensive patients in Australia: a Markov modelling analysis.

BACKGROUND: Primary aldosteronism affects 3-14% of hypertensive patients in the primary care setting and up to 30% in the hypertensive referral units. Although primary aldosteronism screening is recommended in patients with treatment-resistant hypertension, diagnosis at an earlier stage of disease may prevent end-organ damage and optimize patient outcomes. METHODS: A Markov model was used to estimate the cost-effectiveness of screening for primary aldosteronism in treatment and disease (cardiovascular disease and stroke) naive hypertensive patients. Within the model, a 40-year-old patient with hypertension went through either the screened or the unscreened arm of the model. They were followed until age 80 or death. In the screening arm, the patient underwent standard diagnostic testing for primary aldosteronism if the screening test, aldosterone-to-renin ratio, was elevated above 70 pmol/l : mU/l. Diagnostic accuracies, transition probabilities and costs were derived from published literature and expert advice. The main outcome of interest was the incremental cost effectiveness ratio (ICER). RESULTS: Screening hypertensive patients for primary aldosteronism compared with not screening attained an ICER of AU$35 950.44 per quality-adjusted life year (QALY) gained. The results were robust to different sensitivity analyses. Probabilistic sensitivity analysis demonstrated that in 73% of the cases, it was cost-effective to screen at the commonly adopted willingness-to-pay (WTP) threshold of AU$50 000. CONCLUSION: The results from this study demonstrated that screening all hypertensive patients for primary aldosteronism from age 40 is cost-effective. The findings argue in favour of screening for primary aldosteronism before the development of severe hypertension in the Australian healthcare setting.

Multi-stakeholder preferences for the use of artificial intelligence in healthcare: A systematic review and thematic analysis.

INTRODUCTION: Despite the proliferation of Artificial Intelligence (AI) technology over the last decade, clinician, patient, and public perceptions of its use in healthcare raise a number of ethical, legal and social questions. We systematically review the literature on attitudes towards the use of AI in healthcare from patients, the general public and health professionals' perspectives to understand these issues from multiple perspectives. METHODOLOGY: A search for original research articles using qualitative, quantitative, and mixed methods published between 1 Jan 2001 to 24 Aug 2021 was conducted on six bibliographic databases. Data were extracted and classified into different themes representing views on: (i) knowledge and familiarity of AI, (ii) AI benefits, risks, and challenges, (iii) AI acceptability, (iv) AI development, (v) AI implementation, (vi) AI regulations, and (vii) Human - AI relationship. RESULTS: The final search identified 7,490 different records of which 105 publications were selected based on predefined inclusion/exclusion criteria. While the majority of patients, the general public and health professionals generally had a positive attitude towards the use of AI in healthcare, all groups indicated some perceived risks and challenges. Commonly perceived risks included data privacy; reduced professional autonomy; algorithmic bias; healthcare inequities; and greater burnout to acquire AI-related skills. While patients had mixed opinions on whether healthcare workers suffer from job loss due to the use of AI, health professionals strongly indicated that AI would not be able to completely replace them in their professions. Both groups shared similar doubts about AI's ability to deliver empathic care. The need for AI validation, transparency, explainability, and patient and clinical involvement in the development of AI was emphasised. To help successfully implement AI in health care, most participants envisioned that an investment in training and education campaigns was necessary, especially for health professionals. Lack of familiarity, lack of trust, and regulatory uncertainties were identified as factors hindering AI implementation. Regarding AI regulations, key themes included data access and data privacy. While the general public and patients exhibited a willingness to share anonymised data for AI development, there remained concerns about sharing data with insurance or technology companies. One key domain under this theme was the question of who should be held accountable in the case of adverse events arising from using AI. CONCLUSIONS: While overall positivity persists in attitudes and preferences toward AI use in healthcare, some prevalent problems require more attention. There is a need to go beyond addressing algorithm-related issues to look at the translation of legislation and guidelines into practice to ensure fairness, accountability, transparency, and ethics in AI.

Job satisfaction among community drug distributors in the Mass Drug Administration programme in Nigeria: a cross-sectional study.

BACKGROUND: Despite having one of the largest human resources for health in Africa, the delivery of neglected tropical disease (NTD) health interventions in Nigeria has been hampered by health worker shortages. This study assessed factors associated with job satisfaction among community drug distributors (CDDs) supporting the Nigerian NTD programme, with the goal of identifying opportunities to improve job satisfaction in support of NTD control and elimination efforts in Nigeria. METHODS: A health facility-based cross-sectional survey was conducted in 2019 among CDDs in two states with sharply contrasting NTD programme support, Kaduna and Ogun. A multivariate logistic regression model was used to determine the association between respondent characteristics, programme delivery modalities and job satisfaction. RESULTS: Overall, 75.3% and 74.0% of CDDs were categorised as being satisfied with their job in Kaduna and Ogun states, respectively. The component with the highest reported satisfaction was motivation, where 98.9% and 98.6% of CDDs were satisfied, in Kaduna and Ogun, respectively. Participants were least satisfied with remuneration, communication, supplies and materials, as well as workload. Location (rural/urban) and state, years of experience, who delivers training and reimbursement of transport fare during medicine distribution were significantly associated with job satisfaction. CONCLUSIONS: Including multiple health staff and NTD programme cadres in CDD training and providing remuneration to cover transport fares spent during MDA delivery may improve CDDs' job satisfaction both in Ogun and Kaduna states. Given these two states are at opposite ends of the programme support spectrum, such adaptative measures might help improve CDD job satisfaction in the wider Nigerian NTD programme context.

Equity and efficiency in the scaled-up implementation of integrated neglected tropical disease control: the health economics protocol of the COUNTDOWN multicountry observational study in Ghana, Cameroon and Liberia.

INTRODUCTION: Worldwide, millions of individuals are affected by neglected tropical diseases (NTDs). They are frequently the poorest and most marginalised members of society. Their living conditions, among other things, make them susceptible to such diseases. Historically, several large-scale treatment programmes providing mass drug administrations (MDAs) were carried out per single disease but over the last decade there has been an increasing trend towards co-implementation of MDA activities given the resources used for such programmes are often the same. The COUNTDOWN multicountry studies focus on scaled-up implementation of integrated control strategies against four diseases: lymphatic filariasis, onchocerciasis, schistosomiasis and soil-transmitted helminthiasis. The objective of the COUNTDOWN economic study is to assess the multicountry implementation of control interventions in terms of equity, impact and efficiency. METHODS: The health economic study uses different analytical methods to assess the relationship between NTDs and poverty and the cost-effectiveness of different large-scale intervention options. Regression analysis will be used to study the determinants of NTD occurrence, the impact of NTDs on poverty, factors that hinder access to MDAs and the effect of NTDs on quality-of-life of those affected, including disability. Cost-effectiveness analyses of various integration methods will be performed using health economic modelling to estimate the cost and programme impact of different integration options. Here, cost-effectiveness ratios will be calculated, including multivariate sensitivity analyses, using Bayesian analysis. ETHICS AND DISSEMINATION: Ethics approval has been received both at the Liverpool School of Tropical Medicine and in all participating countries. Results of the various substudies will be presented for publication in peer-reviewed journals. STUDY DATES: 1 July 2016 to 30 June-October 2019.

The COUNTDOWN Study Protocol for Expansion of Mass Drug Administration Strategies against Schistosomiasis and Soil-Transmitted Helminthiasis in Ghana.

(1) Background: Current international policy for schistosomiasis and soil-transmitted helminthiasis (STH) control emphasises mass administration of deworming drugs in school-based programmes. However, this approach is insufficient to control the transmission of these diseases, and their burden in non-school cohorts is recognised, albeit under-researched. This research will investigate the feasibility and acceptability of expanding access to praziquantel (PZQ) against schistosomiasis, and albendazole (ALB) against STH, to communities in selected transmission settings in Ghana. (2) Methods: A three-site longitudinal study will be implemented to investigate the effectiveness of expanding treatment strategies for PZQ and ALB to community members. In the context of community mass drug administration (to preschool children, school non-attending children, and adults, including pregnant women), the intervention will be assessed in a random sample of community members, at baseline with follow-up at 6, 12, and 18 months. In each community, 658 participants will be enrolled, and 314 followed up at each time point. The primary outcome measure is the prevalence of infection of Schistosoma haematobium and/or S. mansoni at study endpoint, as assessed by longitudinal surveys. Secondary outcomes are to quantify the infection of schistosomiasis and STH infections in non-treated cohorts, reductions in prevalence of STH, and intensity of schistosomiasis and STH, and treatment coverage. Nested within this study will be qualitative, cost-benefit, and cost-effectiveness evaluations that will explore accessibility, feasibility, and economic impact of expanded treatment from different complementary perspectives. (3) Discussion: Using a multidisciplinary approach, this study will generate evidence for improved availability, acceptability, affordability, and accessibility to deworming drugs against schistosomiasis and STH to individuals and communities in Ghana. This is likely to have considerable research, programmatic, and political value to contribute evidence for national programme policy development within Ghana, and, more broadly, World Health Organization policy development.

Implementing a community vector collection strategy using xenomonitoring for the endgame of lymphatic filariasis elimination.

BACKGROUND: The global strategy for elimination of lymphatic filariasis is by annual mass drug administration (MDA). Effective implementation of this strategy in endemic areas reduces Wuchereria bancrofti in the blood of infected individuals to very low levels. This minimises the rate at which vectors successfully pick microfilariae from infected blood, hence requiring large mosquito numbers to detect infections. The aim of this study was to assess the feasibility of using trained community vector collectors (CVCs) to sample large mosquito numbers with minimal supervision at low cost for potential scale-up of this strategy. METHODS: CVCs and supervisors were trained in mosquito sampling methods, i.e. human landing collections, pyrethrum spray collections and window exit traps. Mosquito sampling was done over a 13-month period. Validation was conducted by a research team as quality control for mosquitoes sampled by CVCs. Data were analyzed for number of mosquitoes collected and cost incurred by the research team and CVCs during the validation phase of the study. RESULTS: A total of 31,064 and 8720 mosquitoes were sampled by CVCs and the research team, respectively. We found a significant difference (F(1,13) = 27.1606, P = 0.0001) in the total number of mosquitoes collected from southern and northern communities. Validation revealed similar numbers of mosquitoes sampled by CVCs and the research team, both in the wet (F(1,4) = 1.875, P = 0.309) and dry (F(1,4) = 2.276, P = 0.258) seasons in the southern communities, but was significantly different for both wet (F(1,4) = 0.022, P = 0.005) and dry (F(1,4 ) = 0.079, P = 0.033) seasons in the north. The cost of sampling mosquitoes per season was considerably lower by CVCs compared to the research team (15.170 vs 53.739 USD). CONCLUSIONS: This study revealed the feasibility of using CVCs to sample large numbers of mosquitoes with minimal supervision from a research team at considerably lower cost than a research team for lymphatic filariasis xenomonitoring. However, evaluation of the selection and motivation of CVCs, acceptability of CVCs strategy and its epidemiological relevance for lymphatic filariasis xenomonitoring programmes need to be assessed in greater detail.

Parental health shocks and schooling: The impact of mutual health insurance in Rwanda.

The goal of this study was to look at the educational spill-over effects of health insurance on schooling with a focus on the Rwandan Community Based Health Insurance Programme, the Mutual Health Insurance scheme. Using a two-person general equilibrium overlapping generations model, this paper theoretically analyses the possible effect of health insurance on the relationship between parental health shocks and child schooling. Individuals choose whether or not they want to incur a medical cost by seeking care in order to reduce the effect of health shocks on their labour market availability and productivity. The theoretical results show that, health shocks negatively affect schooling irrespective of insurance status. However, if the health shock is severe (incapacitating) or sudden in nature, there is a discernible mitigating effect of health insurance on the negative impact of parental ill health on child schooling. The results are tested empirically using secondary data from the third Integrated Household Living Conditions Survey (EICV) for Rwanda, collected in 2011. A total of 2401 children between the ages of 13 and 18 are used for the analysis. This age group is selected due to the age of compulsory education in Rwanda. Based on average treatment effect on treated we find a statistically significant difference in attendance between children with MHI affiliated parents and those with uninsured parents of about 0.044. The negative effect of a father being severely ill is significant only for uninsured household. For the case of the mother, this effect is felt by female children with uninsured parents only when the illness is sudden. The observed effects are more pronounced for older children. While the father's ill health (sever or sudden) significantly and negatively affects their working hours, health insurance plays appears to increase their working hours. The effects of health insurance extend beyond health outcomes.
