Child Income Appropriations as a Disease-Coping Mechanism: Consequences for the Health-Education RelationshipRenaud Bourlès, Bruno Ventelou et Maame Esi Woode, The Journal of Development Studies, Volume 54, Issue 1, pp. 57-71, 2018

This paper analyses the relationships between HIV/AIDS and education taking into account the appropriative nature of child income. Using a theoretical model, we show that considering remittances from one’s child as an insurance asset can reverse the usual negative relationship between disease prevalence and educational investment. This prediction confirms the results of an empirical study conducted on data compiled from the Demographic and Health Survey (DHS) database for 12 sub-Sahara African countries for children aged between 7 and 22-years-old. Using regional HIV prevalence as a measure of health risk, we find that the ‘sign of the slope’ between health risk and the enrolment of children is not constant. Splitting the data based on expected remittance patterns (for example rural versus urban), we obtain that the effect is most likely driven by household characteristics related to child income appropriation.

Community Economic Distress and Changes in Medicare Patients' End-of-Life Care CostsWilliam B. Weeks, Mariétou H. L. Ouayogodé, Bruno Ventelou, Todd Mackenzie et James N. Weinstein, Journal of Palliative Medicine, Volume 21, Issue 6, pp. 742-743, 2018

Real reductions in decedents’ per-capita Medicare fee-forservice
(FFS) spending accounted for most of Medicare’s
cost growth mitigation between 2009 and 2014.1 Decedents’
spending reductions immediately followed the Great Recession
of 2007–2009, which accounted for 14% of the decline
in overall Medicare spending growth between 2009 and
2012.2 Since Medicare patients living in lower income areas
spend more at the end of life (EOL),3 we sought to explore
whether local economic distress levels were associated with
decedents’ spending.

Predicting medical practices using various risk attitude measuresSophie Massin, Antoine Nebout et Bruno Ventelou, The European Journal of Health Economics, Volume 19, Issue 6, pp. 843–860, 2018

This paper investigates the predictive power of several risk attitude measures on a series of medical practices. We elicit risk preferences on a sample of 1500 French general practitioners (GPs) using two different classes of tools: scales, which measure GPs’ own perception of their willingness to take risks between 0 and 10; and lotteries, which require GPs to choose between a safe and a risky option in a series of hypothetical situations. In addition to a daily life risk scale that measures a general risk attitude, risk taking is measured in different domains for each tool: financial matters, GPs’ own health, and patients’ health. We take advantage of the rare opportunity to combine these multiple risk attitude measures with a series of self-reported or administratively recorded medical practices. We successively test the predictive power of our seven risk attitude measures on eleven medical practices affecting the GPs’ own health or their patients’ health. We find that domain-specific measures are far better predictors than the general risk attitude measure. Neither of the two classes of tools (scales or lotteries) seems to perform indisputably better than the other, except when we concentrate on the only non-declarative practice (prescription of biological tests), for which the classic money-lottery test works well. From a public health perspective, appropriate measures of willingness to take risks may be used to make a quick, but efficient, profiling of GPs and target them with personalized communications, or interventions, aimed at improving practices.

The value of specialist care—infectious disease specialist referrals—why and for whom? A retrospective cohort study in a French tertiary hospitalManoj Sasikumar, Sylvie Boyer, Anne Remacle-Bonnet, Bruno Ventelou et Philippe Brouqui, European Journal of Clinical Microbiology & Infectious Diseases, Volume 36, Issue 4, pp. 625-633, 2017

This study evaluated the impact of infectious disease (ID) specialist referrals on outcomes in a tertiary hospital in France. This study tackled methodological constraints (selection bias, endogeneity) using instrumental variables (IV) methods in order to obtain a quasi-experimental design. In addition, we investigated whether certain characteristics of patients have a bearing on the impact of the intervention. We used the payments database and ID department files to obtain data for adults admitted with an ID diagnosis in the North Hospital, Marseille from 2012 to 2014. Comparable cohorts were obtained using coarsened exact matching and analysed using IV models. Mortality, readmissions, cost (payer perspective) and length of stay (LoS) were analysed. We recorded 15,393 (85.97%) stays, of which 2,159 (14.03%) benefited from IDP consultations. The intervention was seen to significantly lower the risk of inpatient mortality (marginal effect (M.E) = –19.06%) and cost of stay (average treatment effect (ATE) = – €5,573.39). The intervention group was seen to have a longer LoS (ATE = +4.95 days). The intervention conferred a higher reduction in mortality and cost for stays that experienced ICU care (mortality: odds ratio (OR) =0.09, M.E cost = –8,328.84 €) or had a higher severity of illness (mortality: OR=0.35, M.E cost = –1,331.92 €) and for patients aged between 50 and 65 years (mortality: OR=0.28, M.E cost = -874.78 €). This study shows that ID referrals are associated with lower risk of inpatient mortality and cost of stay, especially when targeted to certain subgroups.

Take the Money and Run? Hypothetical Fee Variations and French GPs’ Labour SupplyOlivier Chanel, Alain Paraponaris, Christel Protière et Bruno Ventelou, Revue Économique, Volume 68, Issue 3, pp. 357-377, 2017

This paper analyses how French general practitioners? (GPs) labour supply would respond to changes in their fee per consultation, seeking to determine whether there is a backward-bending curve.?Because French GPs? fees only evolve very slowly and are generally fixed by the National Health Insurance Fund, fee variability is not sufficient to observe changes in labour supply.?Therefore, we designed a contingent valuation survey randomly presenting GPs with three hypothetical fee increases.?Empirical evidence from 1,400 GPs supports the hypothesis of a negative slope in their labour supply curve.?This suggests that increasing fees is not an effective policy to increase the supply of medical services.

The expected and unexpected benefits of dispensing the exact number of pillsCarole Treibich, Sabine Lescher, Luis Sagaon-Teyssier et Bruno Ventelou, PloS one, Volume 12, Issue 9, pp. e0184420, 2017

Background:
From November 2014 to November 2015, an experiment in French community pharmacies replaced traditional pre-packed boxes by per-unit dispensing of pills in the exact numbers prescribed, for 14 antibiotics.

Methods:
A cluster randomised control trial was carried out in 100 pharmacies. 75 pharmacies counted out the medication by units (experimental group), the other 25 providing the treatment in the existing pharmaceutical company boxes (control group). Data on patients under the two arms were compared to assess the environmental, economic and health effects of this change in drug dispensing. In particular, adherence was measured indirectly by comparing the number of pills left at the end of the prescribed treatment.

Results:
Out of the 1185 patients included during 3 sessions of 4 consecutive weeks each, 907 patients experimented the personalized delivery and 278 were assigned to the control group, consistent with a 1/3 randomization-rate at the pharmacy level. 80% of eligible patients approved of the per-unit dispensing of their treatment. The initial packaging of the drugs did not match with the prescription in 60% of cases and per-unit dispensing reduced by 10% the number of pills supplied. 13.1% of patients declared that they threw away pills residuals instead of recycling—no differences between groups. Finally, per-unit dispensing appeared to improve adherence to antibiotic treatment (marginal effect 0.21, IC 95, 0.14–0.28).

Conclusions:
Supplying antibiotics per unit is not only beneficial in terms of a reduced number of pills to reimburse or for the environment (less pills wasted and non-recycled), but also has a positive and unexpected impact on adherence to treatment, and thus on both individual and public health.

Decisional needs assessment of patients with complex care needs in primary care: a participatory systematic mixed studies review protocolMathieu Bujold, Pierre Pluye, France Légaré, Jeannie Haggerty, Genevieve C. Gore, Reem El Sherif, Marie-Ève Poitras, Marie-Claude Beaulieu, Marie-Dominique Beaulieu, Paula L. Bush, et al., BMJ Open, Volume 7, Issue 11, pp. e016400, 2017

Introduction Patients with complex care needs (PCCNs) often suffer from combinations of multiple chronic conditions, mental health problems, drug interactions and social vulnerability, which can lead to healthcare services overuse, underuse or misuse. Typically, PCCNs face interactional issues and unmet decisional needs regarding possible options in a cascade of interrelated decisions involving different stakeholders (themselves, their families, their caregivers, their healthcare practitioners). Gaps in knowledge, values clarification and social support in situations where options need to be deliberated hamper effective decision support interventions. This review aims to (1) assess decisional needs of PCCNs from the perspective of stakeholders, (2) build a taxonomy of these decisional needs and (3) prioritise decisional needs with knowledge users (clinicians, patients and managers).
Methods and analysis This review will be based on the interprofessional shared decision making (IP-SDM) model and the Ottawa Decision Support Framework. Applying a participatory research approach, we will identify potentially relevant studies through a comprehensive literature search; select relevant ones using eligibility criteria inspired from our previous scoping review on PCCNs; appraise quality using the Mixed Methods Appraisal Tool; conduct a three-step synthesis (sequential exploratory mixed methods design) to build taxonomy of key decisional needs; and integrate these results with those of a parallel PCCNs’ qualitative decisional need assessment (semistructured interviews and focus group with stakeholders).
Ethics and dissemination This systematic review, together with the qualitative study (approved by the Centre Intégré Universitaire de Santé et Service Sociaux du Saguenay-Lac-Saint-Jean ethical committee), will produce a working taxonomy of key decisional needs (ontological contribution), to inform the subsequent user-centred design of a support tool for addressing PCCNs’ decisional needs (practical contribution). We will adapt the IP-SDM model, normally dealing with a single decision, for PCCNs who experience cascade of decisions involving different stakeholders (theoretical contribution). Knowledge users will facilitate dissemination of the results in the Canadian primary care network.

The extra cost of comorbidity: multiple illnesses and the economic burden of non-communicable diseasesSébastien Cortaredona et Bruno Ventelou, BMC Medicine, Volume 15, Issue 1, pp. 216, 2017

The literature offers competing estimates of disease costs, with each study having its own data and methods. In 2007, the Dutch Center for Public Health Forecasting of the National Institute for Public Health and the Environment provided guidelines that can be used to set up cost-of-illness (COI) studies, emphasising that most COI analyses have trouble accounting for comorbidity in their cost estimations. When a patient has more than one chronic condition, the conditions may interact such that the patient’s healthcare costs are greater than the sum of the costs for the individual diseases. The main objective of this work was to estimate the costs of 10 non-communicable diseases when their co-occurrence is acknowledged and properly assessed.
