Optimizing Communication on HPV Vaccination to Parents of 11- to 14-Year-Old Adolescents in France: A Discrete Choice Experiment

BACKGROUND

With the aim to optimize communication during HPV vaccination campaigns in France, we elicited parental preferences around HPV vaccination.

METHODS

We conducted a single-profile discrete choice experiment (DCE) among parents of 11- to 14-year-old middle-school pupils, who completed an anonymous, self-administered, internet-based questionnaire during 2020-2021. The DCE comprised five attributes (vaccine-preventable disease, justification of optimal age, information on safety, indirect protection and coverage) of vaccination against an unnamed disease that were presented to respondents in ten choice tasks, or scenarios. We use fixed effect logit models to estimate attribute weights on theoretical vaccine acceptance, and random effect linear regression to estimate attribute coefficients on vaccine eagerness (decision and decision certainty). We estimated marginal effects of attributes on expected vaccine acceptance.

RESULTS

Vaccination scenarios were accepted by 55.6-89.2% of the 1291 participants. The largest marginal effects on expected vaccine acceptance in the full sample arose from prevention of cancer versus genital warts (+ 11.3 percentage points); from a "severe side effect suspicion that was not scientifically confirmed" versus a statement about "more benefits than risks" (+ 8.9 percentage points), and information on 80% vaccine coverage in neighbouring countries versus on "insufficient coverage" (+ 4.2 percentage points). Explaining the early age of vaccination by sexual debut had a strong negative impact among French monolingual parents with lower education level (vs age-independent, OR 0.48, 95% CI 0.27-0.86), but not other socio-economic groups. After removing low-quality responses (unvaried certainty and short questionnaire completion), among serial non-demanders with children not vaccinated against HPV, only disease elimination impacted vaccine eagerness positively (coefficient 0.54, 0.06-1.02).

DISCUSSION

Using DCEs to elicit parents' preferences around communication messages, notably on cancer prevention, vaccine coverage and information about vaccine safety, could help to optimize HPV vaccination promotion efforts.

Are the 7C psychological antecedents associated with COVID-19 vaccine behaviours beyond intentions? A cross-sectional study on at-least-one-dose and up-to-date vaccination status, and uptake speed among adults in France

BACKGROUND

Widely documented psychological antecedents of vaccination are confidence in vaccines, complacency, convenience, calculation, collective responsibility (5C model) with the recent addition of confidence in the wider system and social conformism. While the capacity of these seven antecedents (7C) to explain variance in COVID-19 vaccine intentions has been previously documented, we study whether these factors also are associated with vaccine behaviours, beyond intentions.

METHODS

From February to June 2022, we recruited a sample of adults in France, including persons with notified recent SARS-CoV-2 infection, along with relatives and randomly selected non-infected persons. Participants completed self-administered questionnaires assessing COVID-19 vaccination history and the 7C antecedents. We defined vaccination behaviours as three outcomes: at-least-one-dose vaccine status by 2022 (N = 49,019), up-to-date vaccination status (N = 46,566), and uptake speed of first dose (N = 25,998). We conducted multivariable logistic regressions and Cox models.

RESULTS

Among the 49,019 participants, 95.0% reported receipt of at least one dose and 89.8% were up to date with recommendations. All 7C antecedents were significantly associated with the outcomes, although effects were weaker for up-to-date vaccination status and uptake speed. The strongest effects (most vs. least vaccine-favourable attitude level, at-least-one-dose vaccination status) were observed for collective responsibility (OR: 14.44; 95%CI: 10.72-19.45), calculation (OR: 10.29; 95%CI: 7.53-14.05), and confidence in the wider system (OR: 8.94; 95%CI: 6.51-12.27).

CONCLUSION

This study demonstrates that the 7C not only explain vaccine intention, but also vaccine behaviours, and underpins the importance of developing vaccine promotion strategies considering the 7C antecedents.

Preventing autonomy loss with multicomponent geriatric interventions: A resource-saving strategy? Evidence from the SPRINT-T study

Background

The objective of healthy aging strategies is to support interventions targeting autonomy loss prevention, with the assumption that these interventions are likely to be efficient by simultaneously improving clinical outcomes and saving costs.

Methods

We compare the economic impact of two interventions targeting frailty prevention in older European populations: a multicomponent intervention including physical activity monitoring, nutrition management, information and communications technology use and a relatively simple healthy aging lifestyle education program based on a series of workshops. Our sample includes 1,519 male and female participants from 11 European countries aged 70 years or older. Our econometric model explores trends in several outcomes depending on intervention receipt and frailty status at baseline.

Results

Implementing a multicomponent intervention among frail older people does not lead to a lower use of care and do not prevent quality of life losses associated with aging. However, it impacts older people's sense of priorities and interest in the future. We find no statistically significant differences between the two interventions, suggesting that the implementation of a multicomponent intervention may not be the most efficient strategy. The impact of the interventions does not differ by frailty status at baseline.

Conclusions

Our results show the need to implement healthy aging strategies that are more focused on people's interests.

Psychometric validation of a 7C-model of antecedents of vaccine acceptance among healthcare workers, parents and adolescents in France

Support for vaccine decision-making requires a tailored approach taking into account psychological antecedents of vaccine acceptance. We aimed at validating an extended 7C-model of antecedents in three different target population groups (healthcare workers [n = 3870], parents [n = 2002] and adolescents [n = 7118]) and two vaccinations (COVID-19, HPV) in France. We performed a secondary analysis of questionnaires collecting sociodemographic characteristics, attitudes and knowledge on vaccination, and vaccine status and intention. We used standard psychometric techniques to validate a first and second order latent structure, and evaluated their association with vaccine intentionality in three levels (refusal, indecision, acceptance). In all populations, the 7C-model yielded a very good model fit (CFI and TLI > 0.90) and, in comparison with non-nested and nested 5C-models, significantly improved the model performance (Ω2, p < 0.05; Wald's test, p < 0.05). The resulting vaccine readiness score was strongly associated with vaccine intentionality (acceptance vs. indecision: βHCW = 2.93, βParents = 2.41, βAdolescents = 1.34; refusal vs. indecision: βHCW = - 1.68, βParents = - 0.16, βAdolescents = - 0.89.). The addition of confidence in the system and social conformism among antecedents of vaccine acceptance allowed a finer understanding of the continuum moving from refusal to indecision and acceptance. To work with these antecedents in interventional research, appropriate questionnaire items should be developed for various vaccines and target populations.

Can physicians and schools mitigate social inequalities in human papillomavirus vaccine awareness, uptake and vaccination intention among adolescents? A cross-sectional study, France, 2021 to 2022

BackgroundIn France, human papillomavirus (HPV) vaccination coverage varies across socioeconomic levels.AimWe aimed at assessing HPV vaccine awareness, uptake and vaccination intention among adolescents in France.MethodsIn a cluster-randomised study, 13-15-year-old students in 61 French middle schools completed a web-based questionnaire. We used multivariable logistic regression to evaluate determinants of HPV vaccine awareness, self-reported uptake and vaccination intention among unvaccinated students and interaction terms to explore effects of visits to family physician and remembering school lessons on vaccination. The French deprivation index of school municipalities served as proxy for socioeconomic levels.ResultsAmong 6,992 participants, awareness was significantly associated with parental education (odds ratio (OR) = 0.82; 95% confidence interval (CI): 0.71-0.95), language spoken at home (OR = 0.59; 95% CI: 0.52-0.66) and deprivation level (OR = 0.57; 95% CI: 0.44-0.71), regardless of physician visit or school lessons. Vaccine uptake was associated with parental education without a recent physician visit (OR = 0.31; 95% CI: 0.16-0.59, vs OR = 0.64; 95% CI: 0.52-0.78 with a visit, interaction p = 0.045). Vaccination intention among unvaccinated was associated with deprivation level (moderate-low vs low) among students not remembering school lessons on vaccination (OR = 0.17; 95% CI: 0.05-0.62, vs OR = 0.93; 95% CI: 0.51-1.67 remembering school lessons, interaction p = 0.022). Parental education was associated with vaccination intention among students reporting a physician visit (OR = 0.41; 95% CI: 0.26-0.64 vs OR = 1.05; 95% CI: 0.50-2.20 without a visit, interaction p = 0.034).ConclusionOur results suggest that healthcare and school could promote vaccination and mitigate social inequalities in HPV vaccination coverage.

Impact of a COVID-19 certificate requirement on vaccine uptake pattern and intention for future vaccination. A cross-sectional study among French adults

BACKGROUND

In August 2021, France enacted a COVID-19 certificate requirement (vaccination/recovery/test) to access specific services, with mandates for professional groups. We evaluated the impact of this incentive-coercive policy in terms of vaccine uptake equality, future vaccine intention and confidence in authorities' crisis management.

METHODS

In late August 2021, a representative sample of adults (18-75 years) completed an internet-based questionnaire. We classified vaccinated participants by stated reasons for vaccination and estimated adjusted prevalence ratios (aPR) using multivariable Poisson regression. Counterfactual vaccine status assumed non-vaccination of those vaccinated for the certificate. We analysed the association of free-text testimonial themes with level of confidence in authorities.

RESULTS

Among 972 participants, 85.7% were vaccinated or intended vaccination: 3.6% only for certificate/mandate, 17.7% mainly for certificate/mandate plus other reasons, and 64.4% mainly for other reasons. In the counterfactual situation, vaccine uptake would have been significantly more likely among older vs. younger participants (aPR = 1.35) and among those with moderate-high vs. low levels of confidence in authorities for COVID-19 crisis management (aPR = 2.04). In the observed situation, confidence was the only significant determinant of vaccine status (moderate-high vs. low, aPR = 1.39). Among those without genuine motivation for vaccination, professionally active persons were more likely to have ceded to the certificate requirement (aPR = 3.76). Those vaccinated only for the certificate were more likely to express future COVID-19 vaccine intention than unvaccinated persons (aPR = 6.41). Themes significantly associated with lower confidence were criticism of morality (aPR = 1.76) and poor communication by the authorities (aPR = 1.66).

CONCLUSION

The incentive-coercive policy has reduced the negative association of vaccine status with younger age and low confidence in authorities, but may have reinforced isolation of professionally inactive persons. The requirement did not negatively impact future COVID-19 vaccine intention. Future vaccine-incentive policies should pay special attention to populations with low levels of confidence in authorities.

Informing a target product profile for rapid tests to identify HBV-infected pregnant women with high viral loads: a discrete choice experiment with African healthcare workers

BACKGROUND

Elimination of mother-to-child transmission of hepatitis B virus (HBV) requires infant immunoprophylaxis and antiviral prophylaxis for pregnant women with high viral loads. Since real-time polymerase chain reaction (RT-PCR), a gold standard for assessing antiviral eligibility, is neither accessible nor affordable for women living in low-income and middle-income countries (LMICs), rapid diagnostic tests (RDTs) detecting alternative HBV markers may be needed. To inform future development of the target product profile (TPP) for RDTs to identify highly viremic women, we used a discrete choice experiment (DCE) and elicited preference and trade-off of healthcare workers (HCW) in Africa between the following four attributes of fictional RDTs: price, time-to-result, diagnostic sensitivity, and specificity.

METHODS

Through an online questionnaire survey, we asked participants to indicate their preferred test from a set of two RDTs in seven choice tasks with varying levels of the four attributes. We used mixed multinomial logit models to quantify the utility gain or loss generated by each attribute. We attempted to define minimal and optimal criteria for test attributes that can satisfy ≥ 70% and ≥ 90% of HCWs, respectively, as an alternative to RT-PCR.

RESULTS

A total of 555 HCWs from 41 African countries participated. Increases in sensitivity and specificity generated significant utility and increases in cost and time-to-result generated significant disutility. The size of the coefficients for the highest attribute levels relative to the reference levels were in the following order: sensitivity (β = 3.749), cost (β = -2.550), specificity (β = 1.134), and time-to-result (β = -0.284). Doctors cared most about test sensitivity, while public health practitioners cared about cost and midwives about time-to-result. For an RDT with 95% specificity, costing 1 US$, and yielding results in 20 min, the minimally acceptable test sensitivity would be 82.5% and the optimally acceptable sensitivity would be 87.5%.

CONCLUSIONS

African HCWs would prefer an RDT with the following order of priority: higher sensitivity, lower cost, higher specificity, and shorter time-to-result. The development and optimization of RDTs that can meet the criteria are urgently needed to scale up the prevention of HBV mother-to-child transmission in LMICs.

[Analyzing and comparing healthy aging in France and OECD countries based on a new physiological age measure]

We introduce a new individual measure of healthy aging on a sample of more than 39,000 individuals and compare the results for France with 11 other European countries and the United States. Our healthy aging measure is based on the discrepancy between the calendar age of populations with their estimated physiological age, which corresponds to a measure of age adjusted for the effects of comorbidities and functional health. France is ranked in the lower middle of our healthy aging scale, with the Nordic countries (Denmark, Sweden, Netherlands), Switzerland and Greece being ahead. Economic capital has a strong impact on the estimated physiological age and on healthy aging trajectories. Socioeconomic inequalities are particularly marked in France as well as in Italy and the United States. The generosity of long-term care policies seems to be positively associated with the level of healthy aging of the populations. More work is required to identify the drivers of healthy aging among individuals living in OECD countries.

What motivates adults to accept influenza vaccine? An assessment of incentives, ease of access, messaging, and sources of information using a discrete choice experiment

Seasonal influenza vaccination rates remain low, and contribute to preventable influenza cases, hospitalizations, and deaths in the US. While numerous interventions have been implemented to increase vaccine uptake, there is a need to determine which interventions contribute most to vaccine willingness, particularly among age groups with vaccination rates that have plateaued at suboptimal levels. This study aimed to quantify the relative effect of multiple interventions on vaccine willingness to receive influenza vaccine in three age groups using a series of hypothetical situations with different behavioral interventions. We assessed the relative impact of four categories of interventions: source of vaccine messages, type of vaccination messages, vaccination incentives, and ease of vaccine access using a discrete choice experiment. Within each category, we investigated the role of four different attributes to measure their relative contribution to willingness to be vaccinated by removing one option from each of the intervention categories. Among the 1,763 Minnesota residents who volunteered for our study, participants expressed vaccine willingness in over 80% of the scenarios presented. Easy access to drop-in vaccination sites had the greatest impact on vaccine willingness in all age groups. Among the younger age group, small financial incentives also contributed to high vaccine willingness. Our results suggest that public health programs and vaccination campaigns may improve their chances of successfully increasing vaccine willingness if they offer interventions preferred by adults, including facilitating convenient access to vaccination and offering small monetary incentives, particularly for young adults.

Preferences for COVID-19 epidemic control measures among French adults: a discrete choice experiment

In this stated preferences study, we describe for the first time French citizens' preferences for various epidemic control measures, to inform longer-term strategies and future epidemics. We used a discrete choice experiment in a representative sample of 908 adults in November 2020 (before vaccination was available) to quantify the trade-off they were willing to make between restrictions on the social, cultural, and economic life, school closing, targeted lockdown of high-incidence areas, constraints to directly protect vulnerable persons (e.g., self-isolation), and measures to overcome the risk of hospital overload. The estimation of mixed logit models with correlated random effects shows that some trade-offs exist to avoid overload of hospitals and intensive care units, at the expense of stricter control measures with the potential to reduce individuals' welfare. The willingness to accept restrictions was shared to a large extent across subgroups according to age, gender, education, vulnerability to the COVID-19 epidemic, and other socio-demographic or economic variables. However, individuals who felt at greater risk from COVID-19, and individuals expressing high confidence in the governmental management of the health and economic crisis, more easily accepted all these restrictions. Finally, we compared the welfare impact of alternative strategies combining different epidemic control measures. Our results suggest that policies close to a targeted lockdown or with medically prescribed self-isolation were those satisfying the largest share of the population and achieving high gain in average welfare, while average welfare was maximized by the combination of all highly restrictive measures. This illustrates the difficulty in making preference-based decisions on restrictions.

Do not PIMP my nursing home ride! The impact of Potentially Inappropriate Medications Prescribing on residents' emergency care use

Nursing home residents often are poly-medicated, which increases their risks of receiving potentially inappropriate medications. This problem has become a major public health issue in many countries, and in particular in France. Indeed, high uses of potentially inappropriate medication prescriptions can lead to adverse effects that are likely to increase emergency room (ER) visits. However, there is a lack of empirical evidence on the causal relationship between the amount of use of potentially inappropriate medications and ER visit risks among nursing homes residents. Indeed, this question is subject to endogeneity issues due to omitted variables that simultaneously affect inappropriate medications prescriptions and ER use. We take advantage of the IDEM Randomized Clinical Trial (Systematic Dementia Screening by Multidisciplinary Team Meetings in Nursing Homes for Reducing Emergency Department Transfers) to overcome that issue. Indeed, randomization in the IDEM intervention group created exogenous variations in potentially inappropriate prescriptions, and was thus used as an instrument. Using an instrumental variable model, we show that over a 12-month period, a 1% increase in the share of potentially inappropriate medications spending in total medication spending leads to a 5.7 percentage point increase in residents' ER use risks (p < 0.001). This effect is robust to various model specifications. Moreover, the intensity of this correlation persists over an 18-month period. While tackling wasteful spending has become a priority in most countries, our results have important policy implications. Indeed, reducing potentially inappropriate medication spending in nursing homes should be a key component of value-based aging policies, which objectives are to reduce inefficient care, and provide health care services centered in people's interest.

Where Are Populations Aging Better? A Global Comparison of Healthy Aging Across Organization for Economic Cooperation and Development Countries

OBJECTIVES

Global comparisons and large samples are needed to inform policy makers about aging trends among people aged older than 60 years. Using harmonized data gathered from the Gateway to Global Aging data, we introduce a new framework to measure healthy aging across 13 OECD countries.

METHODS

First, we developed an original measure of physiological age (PA), that is, a measure of age weighted for the influence of frailty, activities of daily living limitations, and comorbidities. Second, we compared healthy aging measures across 13 countries based on a ranking of the countries according to the discrepancy between estimated PA and chronological age (CA). Third, we explored the socioeconomic factors associated with healthy aging.

RESULTS

We found a strong correlation between our PA measure and biological age. Italy, Israel, and the United States are the 3 countries where PA is the highest (independent of CA), thus indicating aging in poor health. In contrast, Switzerland, The Netherlands, Greece, Sweden, and Denmark have much lower PA than CA, thus indicating healthy aging. Finally, the PA-CA discrepancy is higher among poorer, less educated, and single older individuals.

CONCLUSIONS

Countries with higher PA need to implement or reinforce healthy aging measures and target the disadvantaged populations.

What drives willingness to receive a new vaccine that prevents an emerging infectious disease? A discrete choice experiment among university students in Uganda

Background

There is a critical need to identify the drivers of willingness to receive new vaccines against emerging and epidemic diseases. A discrete choice experiment is the ideal approach to evaluating how individuals weigh multiple attributes simultaneously. We assessed the degree to which six attributes were associated with willingness to be vaccinated among university students in Uganda.

Methods

We conducted a single-profile discrete choice experiment at Makerere University in 2019. Participants were asked whether or not they would be vaccinated in 8 unique scenarios where attributes varied by disease risk, disease severity, advice for or against vaccination from trusted individuals, recommendations from influential figures, whether the vaccine induced indirect protection, and side effects. We calculated predicted probabilities of vaccination willingness using mixed logistic regression models, comparing health professional students with all other disciplines.

Findings

Of the 1576 participants, 783 (49.8%) were health professional students and 685 (43.5%) were female. Vaccination willingness was high (78%), and higher among health students than other students. We observed the highest vaccination willingness for the most severe disease outcomes and the greatest exposure risks, along with the Minister of Health’s recommendation or a vaccine that extended secondary protection to others. Mild side effects and recommendations against vaccination diminished vaccination willingness.

Interpretation

Our results can be used to develop evidence-based messaging to encourage uptake for new vaccines. Future vaccination campaigns, such as for COVID-19 vaccines in development, should consider acknowledging individual risk of exposure and disease severity and incorporate recommendations from key health leaders.

Study protocol comparing the ethical, psychological and socio-economic impact of personalised breast cancer screening to that of standard screening in the "My Personal Breast Screening" (MyPeBS) randomised clinical trial

Background

The MyPeBS study is an ongoing randomised controlled trial testing whether a risk-stratified breast cancer screening strategy is non-inferior, or eventually superior, to standard age-based screening at reducing incidence of stage 2 or more cancers. This large European Commission-funded initiative aims to include 85,000 women aged 40 to 70 years, without prior breast cancer and not previously identified at high risk in six countries (Belgium, France, Italy, Israel, Spain, UK). A specific work package within MyPeBS examines psychological, socio-economic and ethical aspects of this new screening strategy. It compares women’s reported data and outcomes in both trial arms on the following issues: general anxiety, cancer-related worry, understanding of breast cancer screening strategy and information-seeking behaviour, socio-demographic and economic characteristics, quality of life, risk perception, intention to change health-related behaviours, satisfaction with the trial.

Methods

At inclusion, 3-months, 1-year and 4-years, each woman participating in MyPeBS is asked to fill online questionnaires. Descriptive statistics, bivariate analyses, subgroup comparisons and analysis of variations over time will be performed with appropriate tests to assess differences between arms. Multivariate regression models will allow modelling of different patient reported data and outcomes such as comprehension of the information provided, general anxiety or cancer worry, and information seeking behaviour. In addition, a qualitative study (48 semi-structured interviews conducted in France and in the UK with women randomised in the risk-stratified arm), will help further understand participants’ acceptability and comprehension of the trial, and their experience of risk assessment.

Discussion

Beyond the scientific and medical objectives of this clinical study, it is critical to acknowledge the consequences of such a paradigm shift for women. Indeed, introducing a risk-based screening relying on individual biological differences also implies addressing non-biological differences (e.g. social status or health literacy) from an ethical perspective, to ensure equal access to healthcare. The results of the present study will facilitate making recommendations on implementation at the end of the trial to accompany any potential change in screening strategy.

Vaccine eagerness: A new framework to analyse preferences in single profile discrete choice experiments. Application to HPV vaccination decisions among French adolescents

Background

We previously conducted a single-profile discrete choice experiment to elicit preferences of adolescents around HPV vaccine communication, finding that only half of participants made variable choices (non-uniform respondents) from which preferences were elicited. In this paper we provide a framework to evaluate post-choice certainty information to elicit preferences even among respondents who uniformly accepted (serial demanders) or refused (serial non-demanders) hypothetical vaccination scenarios.

Methods

During an in-class online questionnaire among 1458 French adolescents aged 13–15 years old, we collected certainty levels (0–10) after decisions on nine hypothetical scenarios, including four vaccination attributes: information on vaccine-preventable disease type, on vaccine safety, on potential for indirect protection and on vaccine coverage. We developed a vaccine eagerness scale (ranging from −10 to 10), by combining information on the binary decision (accept vs. refuse the hypothetical vaccine) and the decision certainty level. We used random effects linear regressions to evaluate attributes’ impact on vaccine eagerness. Sensitivity analyses were performed taking into account low response quality, assessed as invariant certainty and low response time.

Results

Attributes’ impact on decision certainty were similar between serial demanders (N = 659) and non-uniform respondents (N = 711): mentioning a positive benefit-risk balance significantly decreased certainty to accept (coefficient −0.93), while information on 80% coverage in other countries (+0.33) and potential for disease elimination (+0.09) increased it. Among serial non-demanders, significant attribute impacts were observed only after exclusion of low-quality responses (N = 31): a potential for disease elimination (coefficient: +0.24) and 80% coverage in other countries (+0.42) significantly increased certainty of refusing vaccination. Combining decision and certainty into a vaccine eagerness indicator allowed analysing preferences in the full sample, including “hesitant” respondents, who were sensitive to the content of the vaccination profile.

Conclusion

Choice certainty informs on respondents’ preferences in single-profile discrete-choice experiments, in particular among those with uniform responses.

•

Preferences are not identified among “uniform respondents” in single profile DCEs.

•

Analysis of post-choice certainty can reveal information on their preferences.

•

We propose a new concept for DCEs on vaccination, “vaccine eagerness”.

•

Vaccine eagerness allows analyzing preferences among serial non-demanders.

Quantifying healthcare and welfare sector workers' preferences around COVID-19 vaccination: a cross-sectional, single-profile discrete-choice experiment in France

OBJECTIVES

To analyse preferences around promotion of COVID-19 vaccination among workers in the healthcare and welfare sector in Fance at the start of the vaccination campaign.

DESIGN

Single-profile discrete-choice experiment. Respondents in three random blocks chose between accepting or rejecting eight hypothetical COVID-19 vaccination scenarios.

SETTING

4346 healthcare and welfare sector workers in France, recruited through nation-wide snowball sampling, December 2020 to January 2021.

OUTCOME

The primary outcomes were the effects of attributes' levels on hypothetical acceptance, expressed as ORs relative to the reference level. The secondary outcome was vaccine eagerness as certainty of decision, ranging from -10 to +10.

RESULTS

Among all participants, 61.1% made uniform decisions, including 17.2% always refusing vaccination across all scenarios (serial non-demanders). Among 1691 respondents making variable decisions, a strong negative impact on acceptance was observed with 50% vaccine efficacy (compared with 90% efficacy: OR 0.05, 95% CI 0.04 to 0.06) and the mention of a positive benefit-risk balance (compared with absence of severe and frequent side effects: OR 0.40, 0.34 to 0.46). The highest positive impact was the prospect of safely meeting older people and contributing to epidemic control (compared with no indirect protection: OR 4.10, 3.49 to 4.82 and 2.87, 2.34 to 3.50, respectively). Predicted acceptance was 93.8% for optimised communication on messenger RNA vaccines and 16.0% for vector-based vaccines recommended to ≥55-year-old persons. Vaccine eagerness among serial non-demanders slightly but significantly increased with the prospect of safely meeting older people and epidemic control and reduced with lower vaccine efficacy.

DISCUSSION

Vaccine promotion towards healthcare and welfare sector workers who hesitate or refuse vaccination should avoid the notion of benefit-risk balance, while collective benefit communication with personal utility can lever acceptance. Vaccines with limited efficacy will unlikely achieve high uptake.

Are long-term care jobs harmful? Evidence from Germany

Like many OECD countries, Germany is currently facing a shortage of long-term care (LTC) workers. This situation is concerning in the context of the ageing of the German population. A potential reason why Germany fails to recruit and retain LTC workers is that LTC jobs are particularly demanding (physical and psychological strain) which may be harmful to health. However, there is a lack of empirical evidence demonstrating this effect. This article fills the gap in the literature by exploring to what extent LTC jobs reduce workers' health over time. We estimate a dynamic panel data model on the German Socio-Economic Panel (v.35; 1984-2018), which allows adressing selection issues into occupations. Our paper provides innovative findings on the impact of LTC occupations on workers' health. We confirm that LTC jobs have a negative impact on self-reported health. Our results have strong policy implications: we emphasize the need to provide sufficient assistance to LTC workers, who are at risk of facing more health issues than other workers. This issue is key to increase the attractiveness of LTC jobs and reduce turnover in the LTC workforce.

FRAILTY, SARCOPENIA AND LONG TERM CARE UTILIZATION IN OLDER POPULATIONS: A SYSTEMATIC REVIEW

This systematic literature review documents the link between frailty or sarcopenia, conceptualized as dimensions of physical health, and the use of long-term care services by older individuals. Long-term care services include formal and informal care provided at home as well as in institutions. A systematic review was performed according to PRISMA requirements using the following databases: PubMed-Medline, Embase, CINAHL, Web of Science, and Academic Search Premier. We included all quantitative studies published in English between January 2000 and December 2018 focusing on individuals aged 50 or more, using a relevant measurement of sarcopenia or physical frailty and a long-term care related outcome. A quality assessment was carried out using the questionnaire established by the Good Practice Task Force Report of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Five subsets of long-term care outcome were considered: 1/ nursing home placement (NHP), 2/ nursing home short stay (NHSS), 3/ formal personal care (FPC), 4/ formal home help (FHH), 5/ informal care (IC). Out of 1943 studies, 17 were finally included in the review. With some studies covering several LTC outcomes, frailty and / or sarcopenia were associated with increased LTC use in 17 out of 26 cases (NHP: 5/6, NHSS: 3/4, FPC: 5/7, FHH: 1/4, IC: 3/5) The association was not consistent in 5 cases (NHP: 1/6, NHSS: 1/4, FPC: 2/7, FHH: 0/4, IC: 1/5) and the association was either not significant or the results inconclusive in the remaining 9 cases. Overall, while results on sarcopenia are scarce, evidence support a positive association between frailty and LTC use. The evidence is stronger for the association of physical frailty with nursing home placement / short stay as well as on FPC. There is less (more heterogeneous) evidence regarding the correlation between physical frailty and FHH or IC use. Results need to be confirmed by more advanced statistical methods or design based on longitudinal data.

Optimising HPV vaccination communication to adolescents: A discrete choice experiment

BACKGROUND

Human Papillomavirus (HPV) vaccine coverage in France is below 30%, despite proven effectiveness against HPV infections and (pre-)cancerous cervical lesions. To optimise vaccine promotion among adolescents, we used a discrete choice experiment (DCE) to identify optimal statements regarding a vaccination programme, including vaccine characteristics.

METHODS

Girls and boys enrolled in the last two years of five middle schools in three French regions (aged 13-15 years) participated in an in-class cross-sectional self-administered internet-based study. In ten hypothetical scenarios, participants decided for or against signing up for a school-based vaccination campaign against an unnamed disease. Scenarios included different levels of four attributes: the type of vaccine-preventable disease, communication on vaccine safety, potential for indirect protection, and information on vaccine uptake among peers. One scenario was repeated with an added mention of sexual transmission.

RESULTS

The 1,458 participating adolescents (estimated response rate: 89.4%) theoretically accepted vaccination in 80.1% of scenarios. All attributes significantly impacted theoretical vaccine acceptance. Compared to a febrile respiratory disease, protection against cancer was motivating (odds ratio (OR) 1.29 [95%-CI 1.09-1.52]), but not against genital warts (OR 0.91 [0.78-1.06]). Compared to risk negation ("vaccine does not provoke serious side effects"), a reference to a positive benefit-risk balance despite a confirmed side effect was strongly dissuasive (OR 0.30 [0.24-0.36]), while reference to ongoing international pharmacovigilance without any scientifically confirmed effect was not significantly dissuasive (OR 0.86 [0.71-1.04]). The potential for indirect protection motivated acceptance among girls but not boys (potential for eliminating the disease compared to no indirect protection, OR 1.57 [1.25-1.96]). Compared to mentioning "insufficient coverage", reporting that ">80% of young people in other countries got vaccinated" motivated vaccine acceptance (OR 1.94 [1.61-2.35]). The notion of sexual transmission did not influence acceptance.

CONCLUSION

HPV vaccine communication to adolescents can be tailored to optimise the impact of promotion efforts.

Health measures and long-term care use in the European frail population

This paper explores the association between health measures and long-term care (LTC) use in the 70+ old population. We examine how different measures of health-subjective versus objective-predict LTC use, provided either formally or informally. We consider an absolute measure of subjective health, the grade given by the individual to his/her health status, and additionally construct a relative measure capturing the difference between this grade and the average grade given to health by individuals sharing the same characteristics. Conceptually, this difference comes from the perception of the individual, corresponding to both the private health information and the reporting behavior affecting self-rated health. We use the baseline data from the SPRINTT study, an ongoing randomized control trial on 1519 subjects facing physical frailty and sarcopenia (PF&S) in 11 European countries. Our sample population is older than 70 (mean: 79 years) and comprises a majority (71%) of women. Results show that self-rated health indicators correlate to formal care even when objective health measures are included, while it is not the case for informal care. Formal care consumption thus appears to be more sensitive to the individual's perception of health than informal care.

Quantifying preferences around vaccination against frequent, mild disease with risk for vulnerable persons: A discrete choice experiment among French hospital health care workers

The individual determinants of vaccine acceptance among health workers (HCWs) have been described in the literature, but there is little evidence regarding the impact of vaccine characteristics and contextual factors (e.g., incentives, communication) on vaccination intentions. We developed a single profile discrete choice experiment (DCE) to assess the impact of seven attributes on stated vaccination intention against an unnamed disease, described as frequent with rapid clinical evolution and epidemic potential (similar to influenza or pertussis). Attributes evaluated vaccine characteristics (effectiveness, security profile), inter-individual aspects (epidemic risk, controversy, potential for indirect protection, vaccine coverage) and incentives (e.g., badge, hierarchical injunction). A total of 1214 French hospital-based HCWs, recruited through professional organizations, completed the online DCE questionnaire. The relative impact of each attribute was estimated using random effects logit models on the whole sample and among specific subgroups. Overall, 52% of included HCWs were vaccinated against influenza during 2017-18 and the average vaccination acceptance rate across all scenarios was 58%. Aside from the management stance, all attributes' levels had significant impact on vaccination decisions. Poor vaccine safety had the most detrimental impact on stated acceptance (OR 0.04 for the level controversy around vaccine safety). The most motivating factor was protection of family (OR 2.41) and contribution to disease control (OR 2.34). Other motivating factors included improved vaccine effectiveness (OR 2.22), high uptake among colleagues (OR 1.89) and epidemic risk declared by health authorities (OR 1.76). Social incentives (e.g., a badge I'm vaccinated) were dissuasive (OR 0.47). Compared to HCWs previously vaccinated against influenza, unvaccinated HCWs who were favorable to vaccination in general were most sensitive towards improved vaccine effectiveness. Our study suggests that vaccine safety considerations dominate vaccine decision-making among French HCWs, while adapted communication on indirect protection and social conformism can contribute to increase vaccination acceptance.

The contribution of the immigrant population to the U.S. long-term care workforce

The long-term care (LTC) sector will soon face a shortage of care workers. The consequences are potentially dramatic, urging the need to design policies aiming at reducing the turnover rate of LTC workers. Immigrant workers are an important part of the LTC workforce. Pooling data from the Annual Social and Economic (ASEC) supplement to the Current Population Survey (CPS) for years 2003-2019, we compare US-born and immigrant LTC workers' propensity to stay in the LTC workforce over one year. We distinguish two categories of LTC workers: personal care workers and nurses. We show that for both categories, naturalized citizens, legal noncitizen immigrants, and unauthorized immigrants have a higher probability of staying in the LTC workforce compared to US-born citizens. We provide two potential explanations: we show that immigrant personal care workers are more likely to report a better health, and that immigrant nurses have a lower wage variation sensitivity. Our results also suggest that wage increases are likely to be associated with higher retention rates in the profession.

Are frail elderly people in Europe high-need subjects? First evidence from the SPRINTT data

Physical frailty and sarcopenia (PF&S) has received growing attention in empirical models of health care use. However, few articles focused on objective measures of PF&S to assess the extent of care consumption among the frail population at risk of dependency. Using baseline data from the SPRINTT study, a sample of 1518 elderly people aged 70+ recruited in eleven European countries, we analyse the association between various PF&S measures and health care / long term care (LTC) use. Multiple health care and LTC outcomes are modelled using linear probability models adjusted for a range of individual characteristics and country fixed effects. We find that PF&S is associated with a significant increase in emergency admissions and hospitalizations, especially among low-income elders. All PF&S measures are significantly associated with increased use of formal and informal LTC. There is a moderating effect of income on LTC use: poor frail elders are more likely to use any of the formal LTC services than rich frail elders. Our results are robust to various statistical specifications. They suggest that the inclusion of PF&S in the eligibility criteria of public LTC allowances could contribute to decrease the economic gradient in care use among the elderly community-dwelling European population.

Determinants of antidementia drug prescription in patients older than 65: A latent class analysis

BACKGROUND

Antidementia drugs (cholinesterase inhibitors and memantine) are still widely prescribed despite their controversial effects and 2011 guidelines that no longer encourage their prescription. The objective was to assess which factors remained determinants of antidementia drug prescriptions.

METHODS

A cross-sectional study was performed in 2013. Patients suffering from dementia, aged 65 and over, identified in the French national health insurance database were included. Because we anticipated a high correlation between age, comorbidities, and health care use, we first identified the patients' health status by a latent class analysis. Second, we performed adjusted logistic regression models. The explanatory variables were patients' health status, gender, prescription of nonpharmacological treatments (physical and speech therapies), prescription of psychotropic drugs, and access to health care.

RESULTS

Among the 3873 patients included, 38% received antidementia drugs. Three latent classes of patients with different health status were identified. Patients with poor health status received significantly fewer antidementia drugs (P < .001). Patients with speech therapy or antidepressant drugs received significantly more antidementia drugs (P < .001), whereas patients with physical therapy received significantly fewer antidementia drugs (P = .006).

CONCLUSION

Antidementia drugs were less likely to be prescribed for patients with poor health status. This result is encouraging for these frail patients who are more vulnerable to the adverse effects of treatments. At the same time, this result encourage targeting specifically patients in good health status for the use of a decision aid, in an attempt to limit prescriptions by involving patients and families.

Frailty transitions and health care use in Europe

OBJECTIVE

There is relative consensus that chronic conditions, disability, and time-to-death are key drivers of age-related health care expenditures. In this paper, we analyze the specific impact of frailty transitions on a wide range of health care outcomes comprising hospital, ambulatory care, and dental care use.

DATA SOURCE

Five regular waves of the SHARE survey collected between 2004 and 2015.

STUDY DESIGN

We estimate dynamic panel data models on the balanced panel (N = 6078; NT = 30 390 observations). Our models account for various sources of selection into frailty, that is, observed and unobserved time-varying and time-invariant characteristics.

PRINCIPAL FINDINGS

We confirm previous evidence showing that frailty transitions have a statistically significant and positive impact on hospital use. We find new evidence on ambulatory and dental care use. Becoming frail has greater impact on specialist compared to GP visit, and frail elderly are less likely to access dental care.

CONCLUSIONS

By preventing transitions toward frailty, policy planners could prevent hospital and ambulatory care uses. Further research is needed to investigate the relationship between frailty and dental care by controlling for reverse causation.

Non-steroids anti-inflammatory drugs and risk of peritonsillar abscess in pharyngitis: a French longitudinal study in primary care†

BACKGROUND

The safety of non-steroids anti-inflammatory drugs (NSAIDs) in the context of pharyngitis is doubtful with contradictory results in the literature.

OBJECTIVE

To evaluate the risk of peritonsillar abscess (PTA) associated to NSAIDs consumption during a pharyngitis episode observed in primary care.

METHOD

A retrospective cohort study using Observatory of General Medicine Datalink from 1995 to 2010. All patients consulting a GP from the Datalink network for pharyngitis have been included. The occurrence of a PTA in the 15 days following the consultation for pharyngitis was matched. The association between PTA and prescriptions of NSAIDs was studied via an adjusted logistic regression model.

RESULTS

During the study period, 105 802 cases of pharyngitis and 48 cases of PTA following a pharyngitis were reported, concerning respectively 67 765 and 47 patients. In the multivariate analysis, the risk of PTA was associated positively with a NSAIDs prescription (OR = 2.9, 95% CI = 1.6-5.2). Other factors associated with PTA occurrence were the prescription of corticosteroids (OR = 3.1, 95% CI = 1.3-7.6) and an age between 20 and 40 years (OR = 5.7, 95% CI = 2.5-13.0). The prescription of antibiotics was not significantly associated with PTA (P = 0.7).

CONCLUSION

Prescription of NSAIDs in pharyngitis may increase the risk of PTA. This study encourages considering cautiously the balance between benefits and harms before prescription of NSAIDs for pharyngitis.

For better or worse? Investigating the validity of best-worst discrete choice experiments in health

Discrete choice experiments (DCEs) are frequently used in health economics to measure preferences for nonmarket goods. Best-worst discrete choice experiment (BWDCE) has been proposed as a variant of the traditional "pick the best" approach. BWDCE, where participants choose the best and worst options, is argued to generate more precise preference estimates because of the additional information collected. However, the validity of the approach relies on two necessary conditions: (a) best and worst decisions provide similar information about preferences and (b) asking individuals to answer more than one choice question per task does not reduce data quality. Whether these conditions hold in empirical applications remains under researched. This is the first study to compare participants' choices across three experimental conditions: (a) BEST choices only, (b) WORST choices only, and (c) BEST and WORST choices (BWDCE). We find responses to worst choices are noisier. Implied preferences from the best only and worst only choices are qualitatively different, leading to different WTP values. Responses to BWDCE tasks have lower consistency, and respondents are more likely to use simplifying decision heuristics. We urge caution in using BWDCE as an alternative to the traditional "pick the best" DCE.

[General practitioners’ preferences towards incentive measures linked with cancer screening]

INTRODUCTION

General practitioners (GPs) play a key role in the delivery of preventive and screening services for breast, cervical, and colorectal cancers. Yet, their current provision of screening services remains low and varies considerably across screening contexts and GPs. This study investigates the determinants of GPs' involvement in cancer screening activities using discrete choice experiment (DCE) methodology.

METHODS

A representative sample of 402 GPs was recruited in France between March and April 2014. The participants completed 12 choice tasks designed to elicit their preferences for 5 cancer screening attributes aimed at increasing their supply of cancer screening services.

RESULTS

GPs are sensitive to both financial and non-financial incentives, such as a compensated training and systematic transmission of information about screened patients, aimed to facilitate communication between doctors and patients. There is also evidence that the preferences differ across screening contexts: GPs appear to be relatively more sensitive to financial incentives for being involved in colorectal cancer screening, whereas they have higher preference for non-financial incentives in breast and cervical cancers.

CONCLUSION

Our study provides new findings for policymakers interested in prioritizing levers to increase the supply of cancer screening services in general practice.

[Eliciting women’s preferences for breast cancer screening]

INTRODUCTION

Over the past decade, the balance between the benefits and harms of breast cancer screening (BCS) has been widely debated. To date, no French study has interrogated women's points of view and preferences (in the economic sense) for this controversial screening. This study aims to bridge this gap. We aimed to elicit women's trade-offs between the benefits and harms of BCS.

METHODS

A discrete choice experiment questionnaire was developed and administered by a survey institute to French women in order to elicit their preferences and trade-offs between the benefits and risks of BCS (i.e., overdiagnosis and false-positive mammography).

RESULTS

Eight hundred and twelve women, representative of the French general population (age, socioeconomic level, and geographical location), completed the survey. The women would be willing to accept on average 14.1 overdiagnosis cases (median = 9.6) and 47.8 women with a false-positive result (median = 27.2) to avoid one BC-related death. Results from our simulations predict that less than 50% of women would be willing to accept 10 overdiagnosis cases (respectively, 30 women with a false-positive mammography) for one BC-related death avoided.

CONCLUSION

Women are sensitive to both the benefits and harms of BC screening and their preferences are highly heterogeneous. Providing balanced information on both benefits and harms to women through an informed decision-making process would be more respectful of women's preferences.

General Practitioner trainers prescribe fewer antibiotics in primary care: Evidence from France

Purpose

Antibiotic prescription is a central public health issue. Overall, 90% of antibiotic prescriptions are delivered to patients in ambulatory care, and a substantial proportion of these prescriptions could be avoided. General Practitioner (GP) trainers are similar to other GPs in terms of sociodemographic and medical activities, but they may have different prescription patterns. Our aim was to compare the antibiotic prescribing rates between GP trainers and non-trainers.

Methods

This observational cross-sectional study was conducted on administrative data claims from the French National Health Insurance. The antibiotic prescribing rate was calculated. The main independent variable was the training status of the GPs. Prescribing rates were adjusted for the various GPs’ characteristics (gender, age, location of the practice, number of visits per GP and the case-mix) in a multiple linear regression analysis.

Results

Between June 2014 and July 2015 the prescribing patterns of 860 GPs were analysed, among which 102 were GP trainers (12%). Over the year 363,580 patients were prescribed an antibiotic out of 3,499,248 visits for 1,299,308 patients seen over the year thus representing around 27.5% of patients. In the multivariate analyses, being a trainer resulted in a significant difference of 6.62 percentage points (IC 95%: [-8.55; -4.69]; p<0.001) in antibiotic prescriptions comparing to being a non-trainer, corresponding to a relative reduction of 23.4%.

Conclusion

These findings highlight the role of GP trainers in antibiotic prescriptions. By prescribing fewer antibiotics and influencing the next generations of GPs, the human and economic burden of antibiotics could be reduced.

Women's Benefits and Harms Trade-Offs in Breast Cancer Screening: Results from a Discrete-Choice Experiment

BACKGROUND

Over the past decade, the benefits and harms balance of breast cancer (BC) screening has been widely debated.

OBJECTIVES

To elicit women's trade-offs between the benefits and harms of BC screening and to analyze the main determinants of these trade-offs.

METHODS

A discrete-choice experiment with seven attributes depicting BC screening programs including varying levels of BC mortality, overdiagnosis, and false-positive result was used. Eight hundred twelve women aged 40 to 74 years with no personal history of BC recruited by a survey institute and representative of the French general population (age, socioeconomic level, and geographical location) completed the discrete-choice experiment. Preference heterogeneity was investigated using generalized multinomial logit models from which individual trade-offs were derived, and their main determinants were assessed using generalized linear models. Screening acceptance rates under various benefits and harms ratios were simulated on the basis of the distribution of individual preferences.

RESULTS

The women would be willing to accept on average 14.1 overdiagnosis cases (median = 9.6) and 47.8 false-positive results (median = 27.2) to avoid one BC-related death. After accounting for preference heterogeneity, less than 50% of women would be willing to accept 10 overdiagnosis cases for one BC-related death avoided. Screening acceptance rates were higher among women with higher socioeconomic level and lower among women with poor health.

CONCLUSIONS

Women are sensitive to both the benefits and the harms of BC screening and their preferences are highly heterogeneous. Our study provides useful results for public health authorities and clinicians willing to improve their recommendations of BC screening on the basis of women's preferences.

Impact assessment of a pay-for-performance program on breast cancer screening in France using micro data

BACKGROUND

A voluntary-based pay-for-performance (P4P) program (the CAPI) aimed at general practitioners (GPs) was implemented in France in 2009. The program targeted prevention practices, including breast cancer screening, by offering a maximal amount of €245 for achieving a target screening rate among eligible women enrolled with the GP.

OBJECTIVE

Our objective was to evaluate the impact of the French P4P program (CAPI) on the early detection of breast cancer among women between 50 and 74 years old.

METHODS

Based on an administrative database of 50,752 women aged 50-74 years followed between 2007 and 2011, we estimated a difference-in-difference model of breast cancer screening uptake as a function of visit to a CAPI signatory referral GP, while controlling for both supply-side and demand-side determinants (e.g., sociodemographics, health and healthcare use).

RESULTS

Breast cancer screening rates have not changed significantly since the P4P program implementation. Overall, visiting a CAPI signatory referral GP at least once in the pre-CAPI period increased the probability of undergoing breast cancer screening by 1.38 % [95 % CI (0.41-2.35 %)], but the effect was not significantly different following the implementation of the contract.

CONCLUSION

The French P4P program had a nonsignificant impact on breast cancer screening uptake. This result may reflect the fact that the low-powered incentives implemented in France through the CAPI might not provide sufficient leverage to generate better practices, thus inviting regulators to seek additional tools beyond P4P in the field of prevention and screening.

Effect of pay-for-performance on cervical cancer screening participation in France

Pay-for-performance (P4P) has been increasingly used across different healthcare settings to incentivize the provision of targeted services. In this study, we investigated the effect of a nationwide P4P scheme for general practitioners implemented in 2012 in France, on cervical cancer screening practices. Using data from a nationally representative permanent sample of health insurance beneficiaries, we analyzed smear test use of eligible women for the years 2006-2014. Our longitudinal sample was an unbalanced panel comprising 180,167 women eligible from 1 to 9 years each. We took into account that during our study period some women were exposed to another incentive for screening participation: the implementation in 2010 of organized screening (OS) in a limited number of areas. To evaluate the effect of P4P, we defined three different measures of smear utilization. For each measure, we specified binary panel-data models to estimate annual probabilities and to compare each estimate to the 2011 baseline level. To explore the combined effect of P4P and OS in areas exposed to both incentives, we computed interaction terms between year dummies and area of residence. We found that P4P had a modest positive effect on recommended screening participation. This effect is likely to be transient as annual smear use, both for the whole sample and among women overdue for screening, increased only in 2013 and decreased again in 2014. The combined effect of P4P and OS on screening participation was not cumulative during the first years of coexistence.

[Contract for improving professional practices: What is the impact perceived by GPs?]

BACKGROUND

The CAPI (contract for improving professional practices) is a voluntary pay for performance scheme for primary care physicians introduced in France in 2009. Our objective was to analyze general practitioners' (GPs) perceptions of the impact of the CAPI on their healthcare practices.

METHOD

The methodology was both qualitative, using thematic analysis of responses to three items of a questionnaire mailed to GPs in 2011, and quantitative using thematic multiple correspondence analysis of responses together with cluster analysis based on the ward aggregation criterion.

RESULTS

A total of 1050 general practitioners answered, 31% had signed a CAPI. For CAPI-participating GPs, the contract was mostly related to changing practices for drug prescription. GPs who did not participate in the CAPI focused on ethical issues. They denounced a conflict of interest between the doctor and the patient and also the risk of patient selection. They connected these concepts to selected indicators. Due to their relationship with the health insurance fund, they feared their freedom of practice would be restricted.

CONCLUSION

GP involvement in designing indicators would favor better balance between economic goals and values of care. The patients' viewpoint should be studied. Pay for performance has been renewed in the 2011. Further studies will analyze the impact of this new scheme in a medical and economic perspective.

Impact of a pay for performance programme on French GPs' consultation length

BACKGROUND

In 2009, a voluntary-based pay for performance scheme targeting general practitioners (GPs) was introduced in France through the 'Contract for Improving Individual Practices' (CAPI).

OBJECTIVE

To study the impact of the CAPI on French GPs' consultation length.

METHODS

Univariate analysis, and multilevel regression analyses were performed to disentangle the different sources of the consultation length variability (intra and inter physician). The dependant variable was the logarithm of the consultation length. Independent variables included patient's sociodemographics as well as the characteristics of GPs and their medical activity.

RESULTS

Between November 2011 and April 2012, 128 physicians were recruited throughout France and generated 20,779 consultations timed by residents. The average consultation length in the sample was 16.8 min. After adjusting for patients' characteristics only, the consultation length of CAPI signatories was 14.1% lower than that observed for non signatories (p<0.001). After adjusting for GPs' characteristics and the case mix, the CAPI was no longer a significant predictor of the consultation length. The results did not change significantly from one type of consultation to another.

CONCLUSION

Although the CAPI was extended to all GPs in 2012, our results provide a cautionary message to regulators about its ability to generate higher quality of care.

Obstacles to the uptake of breast, cervical, and colorectal cancer screenings: what remains to be achieved by French national programmes?

BACKGROUND

In France, equality in access to screening has been one of the main thrusts of public policies implemented between 2009 and 2013 (the national cancer plan). Our aim in this study was to analyse the obstacles to and levers for breast, cervical, and colorectal cancer screening uptake and their trends over time.

METHODS

Based on representative data from the French Health Care and Health Insurance Survey (three independent, cross-sectional surveys: 2006, 2008, and 2010), multivariate logistic regressions were used to model the association between the nonuse of screening for the three cancers and various independent variables. Then, interactions with survey year dummies allowed the changes in the determinants of these cancer screenings over time to be estimated.

RESULTS

Whereas the incentives for screening were strengthened during the period considered, cervical and breast cancer screenings decreased, and colorectal cancer screenings increased sharply (from 18.2% (95% CI = [17.0-19.4]) in 2006 to 38.9% (95% CI = [37.4-40.5] in 2010. Under-users of the three cancer screenings were primarily unskilled workers (ORcervix = 1.64 [1.38-1.95]), individuals without complementary health insurance (ORbreast = 2.05 [1.68-2.51]), or individuals with free complementary health insurance who more rarely use outpatient care. Moreover, individuals reporting either risky behaviours, namely heavy smokers (ORcolorectal = 1.70) and high-risk drinkers (ORcervix = 1.42) or very safe behaviours, namely neither smoking nor drinking, underused screenings. Despite the implementation of national programmes for breast and colorectal cancer screenings, the disparities and inequalities in screening uptake did not decrease over the study period.

CONCLUSIONS

These results demonstrate the need for additional primary prevention efforts targeting the identified under-users by focusing on, for instance, individuals with a very healthy lifestyle. Health authorities could also intensify their efforts to promote increased access to screening for the most disadvantaged individuals.

The effects of obesity and mobility disability in access to breast and cervical cancer screening in france: results from the national health and disability survey

Objectives

We aimed to disentangle the effects of obesity and mobility limitation on cervical and breast cancer screening among community dwelling women.

Methods

The data source was the French national Health and Disability Survey - Household Section, 2008. The Body Mass Index (BMI) was used to categorize obesity status. We constructed a continuous score of mobility limitations to assess the severity of disability (Cronbach's alpha = 0.84). Logistic regressions were performed to examine the association between obesity, mobility limitations and the use of Pap test (n = 8 133) and the use of mammography (n = 7 561). Adjusted odds ratios were calculated (AOR). Interaction terms between obesity and the disability score were included in models testing for effect modifications.

Results

Compared with non-obese women, the odds of having a Pap test in the past 3 years was 24% lower in obese women (AOR = 0.76; 95% CI: 0.65 to 0.89), the odds of having a mammogram in the past 2 years was 23% lower (AOR = 0.77; 95% CI: 0.66 to 0.91). Each time the disability score was 5 points higher, the odds of having a Pap test decreases by 20% (AOR = 0.96; 95% CI: 0.94 to 0.98), the odds of having a mammogram decreases by 25% (AOR = 0.95; 95% CI: 0.94 to 0.97). There was no significant interaction between obesity and disability score.

Conclusion

Obesity and mobility limitation are independently associated with a lower likelihood of cervical and breast cancer screening. Protective outreach and follow-up are necessary to reduce inequalities and thus to reduce health disparities in these vulnerable and high-risk populations of obese women with disabilities.

Why did most French GPs choose not to join the voluntary national pay-for-performance program?

BACKGROUND

In 2009, a voluntary pay for performance (P4P) scheme for primary care physicians was introduced in France through the 'Contract for Improving Individual Practice' (CAPI). Although the contract could be interrupted at any time and without any penalty, two-thirds of French general practitioners chose not to participate. We studied what factors motivated general practitioners not to subscribe to the P4P contract, and particularly their perception of the ethical risks that may be associated with adhering to a CAPI.

METHOD

A cross-sectional survey among French general practitioners using an online questionnaire based on focus group discussion results. Descriptive and multivariate statistical analyses with logistic regression.

RESULTS

A sample of 1,016 respondents, representative of French GPs. The variables that were associated with the probability of not signing a CAPI were "discomfort that patients were not informed of the signing of a P4P contract by their doctors" (OR = 8.24, 95% CI = 4.61-14.71), "the risk of conflicts of interest" (OR = 4.50, 95% CI = 2.42-8.35), "perceptions by patients that doctors may risk breaching professional ethics" (OR = 4. 35, 95% CI = 2.43-7.80) and "the risk of excluding the poorest patients" (OR = 2.66, 95% CI = 1.53-4.63).

CONCLUSION

The perception of ethical risks associated with P4P may have hampered its success. Although the CAPI was extended to all GPs in 2012, our results question the relevance of the program itself by shedding light on potential adverse effects.
