Granger causality between total expenditure on health and GDP in OECD: Evidence from the Toda-Yamamoto approachJournal articleArshia Amiri et Bruno Ventelou, Economics Letters, Volume 116, Issue 3, pp. 541-544, 2012

In this paper, a modified version of the Granger causality test proposed by Toda and Yamamoto is used to investigate causality between GDP and healthcare expenditure in OECD countries. The findings indicate that bidirectional Granger causality is predominant.

La médecine générale vue par les médecins généralistes libérauxJournal articleAlain Paraponaris, Bruno Ventelou, Pierre Verger, Pascale Desprès, Catherine Aubry, Carole Colin, Caroline Bonnet, Thomas Hérault, Rémy Sebbah et Yolande Obadia, Revue française des affaires sociales, Issue 2-3, pp. 29-47, 2011
Évaluation de l'impact des changements épidémiologiques sur la dépense de santé en France pour 2025 : approche par microsimulationJournal articleSophie Thiébaut et Bruno Ventelou, Sciences sociales et santé, Volume 29, Issue 1, pp. 35-68, 2011

Nous proposons une méthode de prédiction de l’évolution des dépenses de santé ambulatoires (i.e. non hospitalières) sous l’effet du vieillissement de la population française à l’horizon 2025. Le modèle intègre deux indicateurs d’états de santé sur lesquels chaque agent de la base de données pourra transiter, par microsimulation, créant ainsi une dynamique épidémiologique individuelle entre bonne et mauvaise santé. À l’aide d’un modèle économétrique de consommation de biens et services de santé, nous déduisons la dépense française en santé en 2025 par agrégation de la population représentative vieillie en 2025. Le support choisi pour la première application de l’outil est la base de données ESPS 2000 de l’IRDES appariée avec l’Échantillon permanent d’assurés sociaux (EPAS). Le thème traité est l’impact de changements épidémiologiques sur le montant des dépenses ambulatoires. Ces simulations ont été réalisées pour trois scénarios épidémiologiques : scénario à dynamique épidémiologique constante, vieillissement en bonne santé et vieillissement en bonne santé + progrès médical (sans prise en compte des effets prix).

Non-adherence to antiretroviral treatment and unplanned treatment interruption among people living with HIV/AIDS in Cameroon: Individual and healthcare supply-related factorsJournal articleSylvie Boyer, Isabelle Clerc, Cécile-Renée Bonono, Fabienne Marcellin, Paule-Christiane Bilé et Bruno Ventelou, Social Science & Medicine, Volume 72, Issue 8, pp. 1383-1392, 2011

In low-income countries, health system deficiencies may undermine treatment continuity and adherence to antiretroviral therapy (ART) that are crucial for the success of large-scale public ART programs. In addition to examining the effects of individual characteristics, on non-adherence to ART and treatment interruption behaviors - i.e. treatment interruption for more than 2 consecutive days during the previous 4 weeks, this study aims to extend our knowledge on the role played by healthcare supply-related characteristics in shaping these two treatment outcomes. These effects are examined using multilevel logistic models applied to a sub-sample of 2381 ART-treated patients followed-up in 27 treatment centers in Cameroon (ANRS-EVAL survey, 2006-2007). Multivariate models show that factors common to both non-adherence and treatment interruption include binge drinking (at the individual-level) and large hospital size (at the healthcare supply-level). Among the individual factors, financial difficulties of paying for HIV-care are the major correlates of treatment interruption [Adjusted Odds Ratio (AOR) 95% confidence interval (CI)Â =Â 11.73(7.24-19.00)]. By contrast, individual factors associated with an increased risk of non-adherence include: having a main partner but not living in a couple compared to patients living in a couple [AOR(95%CI)Â =Â 1.51(1.14-2.01)]; experience of discrimination in the family environment [AOR(95%CI)Â =Â 1.74(1.14-2.65)]; a lack of regular meals [AOR(95%CI)Â =Â 1.93(1.44-2.57)], and switching antiretroviral drugs (ARV) regimen [AOR(95%CI)Â =Â 1.36(1.08-1.70)]. At healthcare facility-level, the main correlate of ART interruption was antiretroviral stock-outs [AOR(95%CI)Â =Â 1.76(1.01-3.32)] whereas the lack of psychosocial support from specialized staff and lack of task-shifting to nurses in medical follow-up were both associated with a higher-risk of non-adherence [respective AOR (95%CI)Â =Â 2.81(1.13-6.95) and 1.51(1.00-3.40)

Measuring and decomposing socioeconomic inequality in healthcare delivery: A microsimulation approach with application to the Palestinian conflict-affected fragile settingJournal articleMohammad Abu-Zaineh, Awad Mataria, Jean-Paul Moatti et Bruno Ventelou, Social Science & Medicine, Volume 72, Issue 2, pp. 133-141, 2011

Socioeconomic-related inequalities in healthcare delivery have been extensively studied in developed countries, using standard linear models of decomposition. This paper seeks to assess equity in healthcare delivery in the particular context of the occupied Palestinian territory: the West Bank and the Gaza Strip, using a new method of decomposition based on microsimulations. Besides avoiding the 'unavoidable price' of linearity restriction that is imposed by the standard methods of decomposition, the microsimulation-based decomposition enables to circumvent the potentially contentious role of heterogeneity in behaviours and to better disentangle the various sources driving inequality in healthcare utilisation. Results suggest that the worse-off do have a disproportinately greater need for all levels of care. However with the exception of primary-level, utilisation of all levels of care appears to be significantly higher for the better-off. The microsimulation method has made it possible to identify the contributions of factors driving such pro-rich patterns. While much of the inequality in utilisation appears to be caused by the prevailing socioeconomic inequalities, detailed analysis attributes a non-trivial part (circa 30% of inequalities) to heterogeneity in healthcare-seeking behaviours across socioeconomic groups of the population. Several policy recommendations for improving equity in healthcare delivery in the occupied Palestinian territory are proposed.

Density of dental practitioners and access to dental care for the elderly: a multilevel analysis with a view on socio-economic inequality.Journal articleLaurence Lupi-Pégurier, Isabelle Clerc-Urmes, Mohammad Abu-Zaineh, Alain Paraponaris et Bruno Ventelou, Health Policy, Volume 103, Issue 2-3, pp. 160-167, 2011

To examine the relations between density of dental practitioners (DDP) and socio-economic and demographic factors shown to affect access to dental care for the elderly.

Does HIV services decentralization protect against the risk of catastrophic health expenditures?: some lessons from Cameroon.Journal articleSylvie Boyer, Mohammad Abu-Zaineh, Jérôme Blanche, Sandrine Loubiere, Cécile-Renée Bonono, Jean-Paul Moatti et Bruno Ventelou, Health services research, Volume 46, Issue 6pt2, pp. 2029-2056, 2011

OBJECTIVE: Scaling up antiretroviral treatment (ART) through decentralization of HIV care is increasingly recommended as a strategy toward ensuring equitable access to treatment. However, there have been hitherto few attempts to empirically examine the performance of this policy, and particularly its role in protecting against the risk of catastrophic health expenditures (CHE). This article therefore seeks to assess whether HIV care decentralization has a protective effect against the risk of CHE associated with HIV infection. DATA SOURCE AND STUDY DESIGN: We use primary data from the cross-sectional EVAL-ANRS

General practitioners and clinical practice guidelines: a reexamination.Journal articleBruno Ventelou, Alain Paraponaris, Isabelle Clerc, Marc-Andre Guerville et Pierre Verger, Medical Care Research and Review : MCRR, Volume 68, Issue 4, pp. 504-518, 2011

General practitioners' (GPs') use of clinical practice guidelines (CPGs) may be influenced by various contextual and attitudinal factors. This study examines general attitudes toward CPGs to establish profiles according to these attitudes and to determine if these profiles are associated with awareness and with use of CPGs in daily practice. The authors conducted a cross-sectional telephone survey of 1,759 French GPs and measured (a) their general attitudes toward CPGs and (b) their awareness and use in daily practice of CPGs for six specific health problems. A bivariate probit model was used with sample selection to analyze the links between GPs' general attitudes and CPG awareness/use. The authors found three GP profiles according to their opinions toward CPGs and a positive association between these profiles and CPG awareness but not use. It is important to build awareness of CPGs before GPs develop negative attitudes toward them.

Job tenure and self-reported workplace discrimination for cancer survivors 2 years after diagnosis: Does employment legislation matter?Journal articleAlain Paraponaris, Luis Sagaon Teyssier et Bruno Ventelou, Health Policy, Volume 98, Issue 2-3, pp. 144-155, 2010

Objectives To assess the risk of leaving employment for cancer survivors 2 years after diagnosis and the role of workplace discrimination in this risk.Methods A representative sample of 4270 French individuals older than 17 and younger than 58 years when diagnosed with cancer in 2002 were interviewed 2 years later. Their occupational status was analyzed with the help of Probit and IV-Probit models.Results Overall, 66% of the cancer survivors who were working at the time of diagnosis were still employed 2 years later. Age, education level, income at diagnosis, work contract, professional status, affective support, relative prognosis at diagnosis, tumor site and treatment have contrasting impacts upon the probability of job loss across gender. Even after having controlled for these variables, self-reported workplace discrimination increases the probability of job loss by 15%.Conclusions Despite protective labor law and favorable health insurance arrangements, French cancer survivors continue to experience problems to stay in or to return to the labor force. Measures targeting only the employment protection of cancer survivors do not seem to be sufficient to end prior social inequalities in job attainment. Intervention for specific populations particularly exposed to job-loss risks would also be needed.

The life cycle of general practitioners' professional motivations: the case of prevention.Journal articleBruno Ventelou, Yves Arrighi, Y. Videau, P. Batifoulier et M. Gadreau, Revue d'Épidémiologie et de Santé Publique, Volume 58, Issue 5, pp. 301-311, 2010

BACKGROUND:
The analysis of "professional motivations", mainly through the possible crowding-out effects between extrinsic and intrinsic motivations, has become an issue of great concern in the economic literature. This paper aims at applying this topic to the healthcare professions where the proper scaling up of pay-for-performance (P4P) policies by public authorities is at stake.

METHODS:
We used a panel of 528 self-employed general practitioners in the "Provence-Alpes-Cote d'Azur" region in France to provide an interpersonal statistical decomposition between extrinsic and intrinsic motivations with regard to preventive actions. Then, we applied a Tobit model in order to specify the main explicative variables of the share of intrinsic motivations entering into physicians' total motivations.

RESULTS:
The relative share of intrinsic motivations was quite high among physicians paid with fixed fees. We found a significant effect of age on intrinsic motivations describing a U-shaped curve which can be interpreted as being the result of a "life cycle of medical motivations" or a generational effect.

CONCLUSION:
The cross-sectional nature of the data does not allow us to draw any conclusions concerning the predominance of the generational effect or the "life cycle effect" on the evolution of the relative share of physician's intrinsic motivations. Nevertheless, the U-shaped relation between intrinsic motivations and age questions the suitability of using uniformly P4P mechanisms. The generations or age groups of self-employed physicians who seem to be less responsive to extrinsic motivations are more likely to favour the introduction of other types of payment schemes (capitation or salary systems) or regulation tools such as clinical practice guidelines.
