Design of a national and regional survey among French general practitioners and method of the first wave of survey dedicated to vaccination

Bulgarian General Practitioners' Communication Styles about Child Vaccinations, Mainly Focused on Parental Decision Making in the Context of a Mandatory Immunization Schedule

The communication practices of general practitioners in relation with vaccines have not been a topic of wide scientific interest. In this article, we outline them in the context of Bulgaria. A representative, cross-sectional, quantitative, face-to-face survey was conducted among 358 Bulgarian general practitioners in 2022 using simple random sampling. We conducted an exploratory factor analysis using questions about the role of the GPs, which measure models of communication. Based on the factor analysis, we distinguished four communication styles. They were called: active communicator, restrictive communicator, informing communicator, and strained communicator. One-way ANOVA and the T-test were carried out to explore the connections between factor scores (communication styles) and other variables. One of the most important results in the study was that the informing physician (emphasizing the choice of the parents) was the most common model in Bulgaria. This is somewhat contradictory, because of the mandatory status of most vaccines. We found connections between the communication styles and other variables-such as the type of settlement, having a hesitant parent in the practice, recommendations of non-mandatory vaccines, and experience with vaccine-preventable diseases. On the basis of the factor analysis and analysis of relationships with other variables, we reached the conclusion that in Bulgaria, hesitant parents are not sufficiently involved in active, effective communication about vaccines by GPs.

Long-term exposure and health risk assessment from air pollution: impact of regional scale mobility

BACKGROUND

The negative effect of air pollution on human health is widely reported in recent literature. It typically involves urbanized areas where the population is concentrated and where most primary air pollutants are produced. A comprehensive health risk assessment is therefore of strategic importance for health authorities.

METHODS

In this study we propose a methodology to perform an indirect and retrospective health risk assessment of all-cause mortality associated with long-term exposure to particulate matter less than 2.5 microns (PM2.5), nitrogen dioxide (NO2) and ozone (O3) in a typical Monday to Friday working week. A combination of satellite-based settlement data, model-based air pollution data, land use, demographics and regional scale mobility, allowed to examine the effect of population mobility and pollutants daily variations on the health risk. A Health Risk Increase (HRI) metric was derived on the basis of three components: hazard, exposure and vulnerability, utilizing the relative risk values from the World Health Organization. An additional metric, the Health Burden (HB) was formulated, which accounts for the total number of people exposed to a certain risk level.

RESULTS

The effect of regional mobility patterns on the HRI metric was assessed, resulting in an increased HRI associated with all three stressors when considering a dynamic population compared to a static one. The effect of diurnal variation of pollutants was only observed for NO2 and O3. For both, the HRI metric resulted in significantly higher values during night. Concerning the HB parameter, we identified the commuting flows of the population as the main driver in the resulting metric.

CONCLUSIONS

This indirect exposure assessment methodology provides tools to support policy makers and health authorities in planning intervention and mitigation measures. The study was carried out in Lombardy, Italy, one of the most polluted regions in Europe, but the incorporation of satellite data makes our approach valuable for studying global health.

General practitioners' compliance with benzodiazepine discontinuation guidelines in patients treated with long-term lorazepam: A case-vignette cross-sectional survey

AIM

To study determinants associated with GPs' compliance with benzodiazepine discontinuation guidelines through a case-vignette of a patient with multimorbidity treated with long-term lorazepam for insomnia.

METHODS

This cross-sectional survey was performed in a sample of French GPs. The questionnaire included items on their characteristics and questions related to the management of a case-vignette with long-term lorazepam use consulting for a prescription renewal. GPs who proposed a dedicated consultation to discuss discontinuation or progressive discontinuation were considered as "following guidelines", while they were considered as "out-of-guidelines" if they proposed immediate discontinuation or decided not to discontinue lorazepam. A backward selection process was used to select factors to be included in the final logistic regression model. The probabilities of out-of-guidelines practice and their 95% confidence interval (95% CI) were then plotted using a heatmap graph.

RESULTS

Of 1,177 GPs, the majority (92.2%) were aware of the necessity to discontinue lorazepam and reported practice consistent with good practice guidelines. Women GPs aged under 50 years had the lowest estimated probability of out-of-guidelines practice. Conversely, men aged over 58 years with high consideration of patient preferences and low concern about the benefit-risk ratio of lorazepam had the highest probability of out-of-guidelines practice (27.3% [18.7%; 34.7%]).

CONCLUSION

GPs largely reported practice compliant with benzodiazepine discontinuation guidelines, although some GPs, mainly older men who overemphasise patient preferences, were more likely to adopt out-of-guidelines practice.

Estimating vaccine confidence levels among healthcare students and staff of a tertiary institution in South Africa: protocol of a cross-sectional survey

INTRODUCTION

The outbreak of novel COVID-19 caught the world off guard in the first quarter of 2020. To stem the tide of this pandemic, there was acceleration of the development, testing and prelicensure approval for emergency use of some COVID-19 vaccine candidates. This led to raised public concern about their safety and efficacy, compounding the challenges of vaccine hesitancy. The onus of managing and administering these vaccines to a sceptical populace when they do become available rests mostly on the shoulders of healthcare workers (HCWs). Therefore, the vaccine confidence levels of HCWs become critical to the success of vaccination endeavours. This proposed study aims to estimate the level of vaccine confidence and the intention to receive a COVID-19 vaccine among future HCWs and their trainers at a specific university in Cape Town, South Africa, and to identify any vaccination concerns early for targeted intervention.

METHODS AND ANALYSIS

This proposed study is a cross-sectional survey study. An online questionnaire will be distributed to all current staff and students of the Faculty of Medicine Health Sciences of Stellenbosch University in Cape Town, South Africa. No sampling strategy will be employed. The survey questionnaire will consist of demographic questions (consisting of six items) and vaccine confidence questions (comprising six items in Likert scale format). Log binomial models will be employed to identify factors associated with vaccine confidence and intention. The strength of association will be assessed using the OR and its 95% CI. Statistical significance will be defined at a p value <0.05.

ETHICS AND DISSEMINATION

Ethics approval has been obtained for the study from Stellenbosch University (Human Research Ethics Committee reference number S19/01/014 (PhD)). The results will be shared with relevant health authorities, presented at conferences and published in a peer-reviewed journal.

Factors associated with influenza vaccination of general medicine interns in Nancy, France, in 2017

Winter flu is an epidemic infectious disease which sometimes causes serious complications in vulnerable people treated in general practice. Currently, the most effective means of prevention is influenza vaccination, which is recommended for healthcare professionals, including general medicine interns. The target of 75% coverage set by WHO for healthcare professional is rarely reached. Our survey provides an assessment of reported influenza vaccination of general medicine interns (GMI) and evaluates factors influencing their vaccination status. A cross-sectional survey was conducted from 27 September to 2 November 2017 in the Faculty of Medicine at the University of Lorraine in France. An anonymous self-administered questionnaire was distributed electronically (SurveyMonkey software) to all GMI. It collected data on their vaccination status and on levers and barriers to influenza vaccination. The data were analysed using SAS 9.4 software. Multivariate analysis helped identify factors associated with their influenza vaccination status. Of the 595 GMI invited, 269 participated in the survey, with a response rate of 45.2%. During the 2015, 2016, and 2017 winters, overall self-declared vaccine coverage was 37.9, 49.4, and 56.5%, respectively. Being at the end of training (p = 0.008, OR = 3.2), the presence of a mobile vaccination team (p = 0.019, OR = 3.1), and recommending vaccination to one's relatives and friends (p < 0.0001, OR = 5.4) were the three factors independently associated with influenza vaccination. The two main reasons which had a strong influence on non-vaccination were forgetting to do so (30.5%) and lack of time (24.8%). Influenza vaccination coverage of GMI in Nancy falls well short of WHO targets. Vaccination campaigns and facilitated access to vaccination at study and work placement locations should be considered.

Unexplained variations in general practitioners' perceptions and practices regarding vaccination in France

Background

Given geographical disparities in vaccination coverage (VC) and the crucial role general practitioners (GPs) play in vaccination in France, we sought to: 1) determine the existence of geographical variations in GPs' perceptions of vaccines, their trust in information sources, and the frequency of their recommendations to patients by comparing data from southeast (SE), central-west (CW), northwest (NW), and the rest of France; and 2) identify individual and contextual factors associated with regional variations in GPs' recommendations.

Methods

This cross-sectional observational study in 2014 collected data from a panel of 2586 French GPs in private practice: 3 specific regional samples and a fourth sample for the rest of France. We calculated a composite score summarizing GPs' vaccine recommendation frequency for 6 vaccine situations and used a five-step hierarchical linear regression to study the score's links with practice location and individual and contextual factors.

Results

GPs' vaccine recommendation frequency score was highest in NW France and lowest in the SE. The low SE score was explained by GPs' greater doubts about vaccine utility and risks and lower trust in information sources. The high NW score was partially explained by greater adherence to guidelines by GPs there. The contextual factors studied did not explain regional differences.

Conclusion

The geographical variations in GPs' vaccination-related attitudes and practices suggest that vaccine hesitancy among GPs differs in prevalence between regions. These variations coincide with north/south trends in population VC. Intervention strategies to restore confidence in vaccines should target GPs and must be adapted to each regional context.

GPs' management of polypharmacy and therapeutic dilemma in patients with multimorbidity: a cross-sectional survey of GPs in France

BACKGROUND

GPs are confronted with therapeutic dilemmas in treating patients with multimorbidity and/or polypharmacy when unfavourable medication risk-benefit ratios (RBRs) conflict with patients' demands.

AIM

To understand GPs' attitudes about prescribing and/or deprescribing medicines for patients with multimorbidity and/or polypharmacy, and factors associated with their decisions.

DESIGN AND SETTING

Cross-sectional survey in 2016 among a national panel of 1266 randomly selected GPs in private practice in France.

METHOD

GPs' opinions and attitudes were explored using a standardised questionnaire including a case vignette about a female treated for multiple somatic diseases, sleeping disorders, and chronic pain. Participants were randomly assigned one of eight versions of this case vignette, varying by patient age, socioprofessional status, and stroke history. Backward selection was used to identify factors associated with GPs' decisions about drugs they considered inappropriate.

RESULTS

Nearly all (91.4%) responders felt comfortable or fairly comfortable deprescribing inappropriate medications, but only 34.7% decided to do so often or very often. In the clinical vignette, most GPs chose to discontinue symptomatic medications (for example, benzodiazepine, paracetamol/tramadol) because of unfavourable RBRs. When patients asked for ketoprofen for persistent sciatica, 94.1% considered this prescription risky, but 25.6% would prescribe it. They were less likely to prescribe it to older patients (adjusted odds ratio [AOR] 0.48, 95% confidence interval [CI] = 0.36 to 0.63), or those with a stroke history (AOR 0.55, 95% CI = 0.42 to 0.72).

CONCLUSION

In therapeutic dilemmas, some GPs choose to prioritise patients' requests over iatrogenic risks. GPs need pragmatic implementation tools for handling therapeutic dilemmas, and to improve their skills in medication management and patient engagement in such situations.

French guidelines for the outpatient management of Ebola virus disease: Applicability by family physicians

BACKGROUND

During the last alarming Ebola Virus Disease (EVD) outbreak, the French Ministry of Health developed guidelines for the outpatient management of EVD. We aimed to assess family physicians' (FP) knowledge of EVD, to assess their working conditions, and to collect their opinion about the applicability of these guidelines in France.

METHODS

Cross-sectional quantitative study (telephone or email) performed (November 2014-June 2015) during the EVD outbreak. Relevant results were further analyzed with a qualitative study (interviews) based on grounded theory (June-September 2016), after the end of the EVD outbreak.

RESULTS

Thirty-three FPs out of 100contacted answered our survey (response rate: 33%). We interviewed five FPs. Their knowledge of EVD was good. Information sent by post, especially from the national medical association, was considered the best means of information and was preferred to emails. Compliance with guidelines was based on their ease of understanding and application (common sense). The main difficulty in applying these guidelines was the unusual recommended equipment that seemed unnecessary as the management of these patients was based on their interview (anamnesis) and isolation without examination. EVD had little impact on the FPs' practice, they only trained their secretaries to screen for suspected EVD patients and refer them to the mobile emergency unit.

CONCLUSION

FPs had good knowledge of EVD and guidelines. This seemed important to prevent the outbreak in France as they were ready to cope with such a situation, thanks to guidelines they could easily adjust to their practice.

Opioid Analgesics Prescription to End-of-Life Cancer Patients: Characteristics, Attitudes, and Practices of French General Practitioners

Background: Pain management, especially at the end of life, varies depending on the prescriber's characteristics and attitudes. Little is known about the practices of general practitioners (GPs) regarding end-of-life management for patients with cancer. Objectives: To provide an overview of the characteristics associated with GPs' attitudes and practices regarding opioids prescribing and to explore GPs' perceived role and difficulties in managing end-of-life care for patients with cancer. Design: A cross-sectional study (December 2015 to March 2016). Subjects and Analyses: Data were collected from a representative sample of 376 GPs in southeastern France recruited to participate in a survey on medical practices and opinions regarding cancer patient management. Descriptive analyses and multivariate logistic regressions were conducted to study the characteristics, attitudes, and practices associated with GPs' opioids prescribing attitudes. Results: Almost 97% of GPs stated that they prescribe opioids to end-of-life cancer patients. Among these, 77% said that they prescribe opioids on their own initiative, while 23% declared doing so in coordination with a specialist team. Female GPs, GPs working in solo practices, and GPs reporting more difficulties in managing end-of-life cancer patients were significantly less likely to prescribe opioids on their own initiative. Conclusion: Our results suggest that GPs' characteristics and practices influence the prescribing attitudes at the end of life. Given the dearth of studies on this topic, further research is recommended to better understand the impact of GPs' characteristics on their prescriptive attitudes. The possible interactions between patients' and physicians' characteristics-in particular gender-should also be investigated.

The practices of French general practitioners regarding screening and counselling pregnant women for tobacco smoking and alcohol drinking

OBJECTIVES

Our study aims to describe French general practitioners' (GPs') practices toward pregnant patients regarding alcohol consumption and smoking and to highlight factors associated with specific practices.

METHODS

In 2015, a representative sample of 1414 French GPs completed a telephone survey based on a stratified random sampling.

RESULTS

61% of GPs declared screening for alcohol use and 82% for smoking at least once with each pregnant patient; quitting was not systematically advised either for alcohol or for smoking. GPs' practices were significantly better among those who had more recent ongoing training. GPs who drank regularly were less likely to screen for alcohol use and GPs' drinking frequency was inversely related to recommending quitting. Current and former smokers were less likely to recommend quitting to pregnant patients smoking over five cigarettes per day.

CONCLUSIONS

Screening and counselling practices for substance use during pregnancy are heterogeneous among French GPs and are notably related to their personal consumption. GP's role in preventing substance use during pregnancy could be strengthened by actions regarding their own consumption and by modifications in their initial and ongoing training.

General practitioners' perceptions of vaccination controversies: a French nationwide cross-sectional study

OBJECTIVES

We aimed to study general practitioners' (GPs') perceptions of vaccines that have been a subject of controversy in France.

METHODS

A cross-sectional survey in 2014 asked a representative national sample of GPs, randomly selected from the exhaustive database of health professionals in France, about their perceptions of the likelihood of serious adverse events potentially associated with six different vaccines: for two of them the association was based on some scientific evidence, whereas for the other four this is not the case. We performed a cluster analysis to construct a typology of GPs' perceptions about the likelihood of these potential six associations. Factors associated with certain clusters of interest were identified using logistic regression models.

RESULTS

Overall, 1582 GPs participated in the questionnaire survey (1582/1712 GPs who agreed to participate, 92%). Cluster analysis identified four groups of GPs according to their susceptibility to vaccine controversies: 1) limited susceptibility to controversies (52%); 2) overall unsure, but rejected the association between hepatitis B vaccine and multiple sclerosis (32%); 3) highly susceptible to controversies (11%); and 4) unsure (5%). We found that GPs who occasionally practised alternative medicine (OR 2.71, 95% CI 1.65-4.45), and those who considered information provided by mass media as reliable (OR 2.04, 95% CI 1.65-3.99) were more susceptible to controversies.

CONCLUSIONS

GPs had different profiles of susceptibility to vaccination controversies, and most of their perceptions of these controversies were not based on scientific evidence.

General practitioners and vaccination of children presenting with a benign infection

PURPOSE

To assess the self-reported vaccination behavior of general practitioners (GPs) when asked whether they would recommend the vaccination of a child presenting with a febrile uncomplicated common cold.

METHODS

We performed a cross-sectional survey in 2014 on a national sample of GPs. GPs were randomly assigned to one of eight clinical vignettes, all describing a child presenting with an uncomplicated febrile common cold, but differing by age (4 or 11 months), temperature (38°C or 39°C), and the mother's emotional state (calm or worried). GPs were asked whether they would recommend immediate vaccination of the child with a hexavalent vaccine (diphtheria, tetanus, pertussis, poliomyelitis, Haemophilus influenzae type b, and hepatitis B), or postpone it. We investigated the relation between the GPs' recommendation to vaccinate, the clinical vignette's variables, and the GPs' perceptions, attitudes, and practices toward vaccination in a multivariate model.

RESULTS

Among the 1582 participating GPs, 6% recommended immediate vaccination. This behavior was more frequent with a temperature of 38°C rather than 39°C (10% vs. 3%, P<0.001). GPs who felt comfortable giving explanations about vaccine safety were more likely to recommend immediate vaccination of the febrile child (P=0.045), but none of the other GPs' characteristics were associated with their vaccination behavior.

CONCLUSIONS

Almost all GPs postponed the hexavalent vaccination of the febrile child presenting with an uncomplicated viral disease; fever being the major factor affecting their decision. More research is needed on vaccination responses in sick children, as well as clearer guidelines.

Low Uptake of Meningococcal C Vaccination in France: A Cross-sectional Nationwide Survey of General Practitioners' Perceptions, Attitudes and Practices

BACKGROUND

Meningococcal C glycoconjugate vaccine (MenCV) has been recommended in France since 2010, but its uptake remains low (64% coverage among 2-year-olds in 2014). Because general practitioners (GPs) are the cornerstone of the French vaccination program, we sought to assess their perceptions, attitudes, practices and recommendations to patients for this vaccine.

METHODS

A cross-sectional survey in 2014 asked a national sample of 1582 GPs if they would recommend MenCV for patients 12 months of age (routine vaccination) and 2-24 years of age (catch-up vaccination) and explored the barriers to vaccination.

RESULTS

Overall, 52% of GPs (800/1547) reported they always recommend routine MenCV vaccination and 33% (523/1572), catch-up vaccination. The most frequently reported barriers to vaccination were that parents have never heard of this vaccine (72%, 1094/1523), underestimate the risk of contracting meningococcal disease (69%, 1049/1514) and are unaware of its seriousness (55%, 838/1537). In multivariate analyses, GPs recommended routine and catch-up vaccination significantly more often when they had no doubt about the utility and safety of this vaccine, when they thought that the official MenCV recommendation was clear and when their own children were vaccinated. GPs who reported that their patients either were unaware of the severity of bacterial meningitis (P = 0.012) or had no doubts about the efficacy of MenCV recommended catch-up vaccination more often (P = 0.015).

CONCLUSIONS

GPs did not appear to recommend MenCV often enough. Our results suggest that clearer recommendations and a better communications campaign directed at patients and healthcare workers could be useful.

Prevalence and correlates of vaccine hesitancy among general practitioners: a cross-sectional telephone survey in France, April to July 2014

This article sought to estimate the prevalence of vaccine hesitancy (VH) among French general practitioners (GPs) and to study its demographic, professional and personal correlates. We conducted a cross-sectional telephone survey about GPs' vaccination-related attitudes and practices in 2014 in a national panel of 1,712 GPs in private practice, randomly selected from an exhaustive database of health professionals in France. A cluster analysis of various dimensions of VH (self-reported vaccine recommendations, perceptions of vaccine risks and usefulness) identified three clusters: 86% of GPs (95% confidence interval (CI): 84-88) were not or only slightly vaccine-hesitant, 11% (95% CI: 9-12) moderately hesitant and 3% (95% CI: 3-4) highly hesitant or opposed to vaccination. GPs in the latter two clusters were less frequently vaccinated and reported occasional practice of alternative medicine more often than those in the first cluster; they also described less experience with vaccine-preventable diseases and more experience with patients who they considered had serious adverse effects from vaccination. This study confirms the presence of VH among French GPs but also suggests that its prevalence is moderate. Given GPs' central role in vaccination, these results nevertheless call for a mobilisation of stakeholders to address VH among GPs.

Opening the 'Vaccine Hesitancy' black box: how trust in institutions affects French GPs' vaccination practices

BACKGROUND

In recent years, vaccine hesitancy among health professionals has emerged as an important issue on public health agendas. However, we do not yet know very much about whether, and if so how, trust in institutions affects their practices.

METHODS

A path analysis model explaining the influence of trust on GPs' vaccine hesitancy was applied to a cross-sectional survey of 1,582 French GPs performed in 2014. We hypothesized that distrust in public health institutions influences GPs' concerns about the safety of various vaccines, their perceptions about the importance of vaccination, their self-efficacy in the doctor-patient relationship, and ultimately their vaccination recommendations to patients.

RESULTS

GPs' trust in institutions was found to be significantly associated with lower vaccine hesitancy, an association mediated to a large extent by the vaccine's perceived safety (β = 0.09, P < 0.01) and the importance of vaccination (β = 0.46, P < 0.001).

CONCLUSION

These results suggest that restoration of high vaccination coverage may require the re-establishment of a significant degree of trust in the public health system among health professionals.

General practitioners' attitudes and behaviors toward HPV vaccination: A French national survey

OBJECTIVE

General practitioners (GPs) play a crucial role in human papillomavirus (HPV) vaccine acceptance in France. We sought to study: (1) GPs' perceptions of its risks and efficacy and their recommendation behavior; (2) the relative importance of factors associated with the frequency of their recommendations.

METHODS

Cross-sectional observational study in 2014 nested in a national panel of 1712 randomly selected GPs in private practice in France (response rate: 92.4%). We used model averaging to analyze the associations of self-reported frequency of GPs' HPV vaccine recommendations with their perception of its risk-benefit balance and their opinions about the utility of vaccines in general.

RESULTS

Overall, 72% of participants reported frequently recommending HPV vaccination; 60% considered that not enough is known about its risks. The model averaging showed that the factors most associated with infrequent recommendation of this vaccine by GPs were: unfavorable perceptions of its risk-benefit balance (OR=0.13; 95%CI=0.09-0.21; partial R(2)=0.10), a decision not to vaccinate one's own daughter(s) with this vaccine (OR=0.13; 95%CI=0.07-0.24; partial R(2)=0.05), and doubts about vaccine utility in general (OR=0.78; 95%CI=0.71-0.86; partial R(2)=0.03).

CONCLUSION

Although nearly three-quarters of French GPs frequently recommended the HPV vaccine, our findings indicate that a substantial percentage of them are hesitant about it. Doubts about its risks and efficacy strongly influence their recommendation behavior. More research is warranted to help design and evaluate tailored tools and multicomponent intervention strategies to address physician's hesitancy about this vaccine.
