Motivational interview training improves self-efficacy of GP interns in vaccination consultations: A study using the Pro-VC-Be to measure vaccine confidence determinants.

Immunization-specific motivational interviewing (MI), a patient-centered communication style used to encourage internal motivation for attitudinal and behavioral change, can provide healthcare professionals (HCPs) with the skills and practice required to respond to patients' doubts and concerns related to vaccines. We sought to assess the impact of an MI-training of General Practitioner (GP) interns on the psychosocial determinants of their vaccine confidence and behaviors. French GP interns participated in a virtual three-day MI-workshop in southeastern France. We used the validated Pro-VC-Be questionnaire - before and after the MI-workshop spanning over three months - to measure the evolution of these determinants. Scores before and after workshop trainings were compared in pairs. Participants' scores for commitment to vaccination (+10.5 ± 20.5, P = .001), perceived self-efficacy (+36.0 ± 25.8, P < .0001), openness to patients (+18.7 ± 17.0, P < .0001), and trust in authorities (+9.5 ± 17.2, P = 0.01) significantly increased after the training sessions, but not the score for confidence in vaccines (+1.5 ± 11.9, P = .14). The effect sizes of the four score improvements were moderate to large, with self-efficacy and openness to patients having the largest effect sizes (P = .83 and 0.78, respectively). This study provides evidence that certain determinants of overall vaccine confidence in HCPs, reflected respectively in the openness to patients and self-efficacy scores of the Pro-VC-Be, improve after immunization MI-training workshops. Incorporating immunization-specific MI-training in the curriculum for HCPs could improve several necessary skills to improve HCP-patient relationships and be useful for vaccination and other healthcare services.

Assessment of training of general practice interns in motivational interviews about vaccination.

The effectiveness of motivational interviewing (MI) for reducing vaccine hesitancy (VH) has been demonstrated in Quebec. We conducted a study to evaluate the acquisition of MI skills after MI training via videoconferencing for interns training as general practitioners (GPs) in southeastern France. A vaccination-specific MI training workshop was offered to interns in 2021, consisting of two separate Zoom videoconference sessions. Participants completed the Motivational Interviewing Skills in Immunization questionnaire before and after the training to measure skills acquisition. We used pairwise exact Wilcoxon-Pratt signed rank tests for the analysis. Among 45 GP interns enrolled in the first MI session, 34 (75.6%) attended both sessions and completed the questionnaire at 3 different time points. After the first session, MI knowledge scores improved significantly (+21.1 ± 21.6; P < .0001), as did application of MI skills (+36.8 ± 36.7; P < .0001), and MI practice confidence (+21.2 ± 11.1; P < .0001). The second MI session maintained the skills developed after the first session without further improvement. Participant satisfaction was high. This is the first study in France assessing the impact of a vaccination-specific MI training for GP interns. It shows a substantial improvement in knowledge, application of MI skills, and self-confidence in the practice of MI. GP interns were highly satisfied with the training despite the videoconference format. These promising results will allow the integration of MI training in GP medical curricula in order to prepare future GPs for communication in the field of vaccination.

Incidence of leptospirosis in the French armed forces from 2004 to 2018: Retrospective analysis.

BACKGROUND: The French military personnel may be exposed to leptospirosis during their training or on duty on the field in continental France, and most of all, in intertropical areas in the French departments and in Africa. The aim of this study was to assess the incidence of leptospirosis from epidemiological surveillance and cases data from 2004 to 2018, and to propose tools to assess leptospirosis risk prior to any mission or leisure activity. METHOD: A retrospective epidemiological study on leptospirosis cases among French Armed Forces was conducted. More data were collected for 2 clusters in Martinique, as most of leptospirosis cases among French military personnel were identified in Martinique. RESULTS: Eighty-eight cases of leptospirosis were reported, 15 cases in continental France and 73 cases in overseas (including 42 cases in the French West Indies). The global leptospirosis incidence rate in continental France was 0.3/100,000 person-years and in overseas 24/100,000 person-years with the higher incidence rate in Martinique (99/100,000 person-years) and in Mayotte (36.9/100,000 person-years). For the clusters in Martinique, between January and June 2009, 7 cases were declared; between 2016 and 2018, 16 cases were reported, high proportions of severe cardiac, renal and neurological forms (6/16) and hospitalizations (9/16). CONCLUSION: The occupational risk is real in French Armed Forces, particularly in malaria-free intertropical areas where chemoprophylaxis by doxycycline is not applied. Prevention can be optimized by the use of practical tools such as tables and cartographies, leading to a better leptospirosis risk assessment and application of preventive recommendations.

Level of agreement between physician and patient assessment of non-medical health factors.

Background: GPs need to consider assorted relevant non-medical factors, such as family or work situations or health insurance coverage, to determine appropriate patient care. If GPs' knowledge of these factors varies according to patients' social position, less advantaged patients might receive poorer care, resulting in the perpetuation of social inequalities in health. Objective: To assess social disparities in GPs' knowledge of non-medical factors relevant to patient care. Methods: Observational survey of GPs who supervise internships in the Paris metropolitan area. Each of the 52 enrolled GPs randomly selected 70 patients from their patient list. Their knowledge of five relevant factors (coverage by publicly funded free health insurance, or by supplementary health insurance, living with a partner, social support and employment status) was analysed as the agreement between the patients' and GPs' answers to matching questions. Occupational, educational and financial disparities were estimated with multilevel models adjusted for age, sex, chronic disease and GP-patient relationship. Results: Agreement varied according to the factor considered from 66% to 91%. The global agreement score (percentage of agreement for all five factors) was 72%. Social disparities and often gradients, disfavouring the less well-off patients, were observed for each factor considered. Social gradients were most marked according to perceived financial situation and for health insurance coverage. Conclusion: GPs must be particularly attentive toward their least advantaged patients, to be aware of the relevant non-medical factors that affect these patients' health and care, and thus provide management adapted to each individual's personal situation.

Effect of Automobile Travel Time Between Patients' Homes and Ophthalmologists' Offices on Screening for Diabetic Retinopathy.

PURPOSE: The accessibility of ophthalmologists appears to influence the quality of screening for diabetic retinopathy (DR). The principal objective of this study was to analyze the effect of automobile travel time to the closest ophthalmologist on the time to DR screening. METHODS: This historical cohort study used reimbursement databases from the principal national health insurance fund. Patients were included if they had been reimbursed at least thrice for oral antidiabetic medications in the 12 months before the study start date. Patients were followed up from January 1, 2008, for 4 years. The expected event was a DR screening by an ocular fundus examination. The automobile travel time to the nearest ophthalmologist was calculated by the distance between communes, estimated by appropriate software. A Kaplan-Meier curve and a multivariate Cox model were used to model the effect of travel time on the time until DR screening. A sensitivity analysis of travel time described the results of the Cox model. RESULTS: At the start of 2008, 6,573 patients living in 328 different municipalities were included. The multivariate model found that patients living 60 min or more away from an ophthalmologist had a lower instantaneous probability of DR screening than those living <30 min away (adjusted risk ratio = 0.82; 95% confidence interval 0.71-0.95; p = 0.009). The sensitivity analysis showed that this difference became significant at 35 min of travel time. CONCLUSION: Increased automobile travel time for patients with diabetes to the nearest ophthalmologist was associated with a longer time to DR screening.

Effectiveness of seasonal influenza vaccination in patients with diabetes: protocol for a nested case-control study.

INTRODUCTION: Seasonal influenza vaccination (SIV) is recommended for people with diabetes, but its effectiveness has not been demonstrated. All of the available studies are observational and marred with the healthy vaccine bias, that is, bias resulting from the generally better health behaviours practised by people who choose to be vaccinated against influenza, compared with those who do not. This protocol is intended to study the effectiveness of SIV in people with treated diabetes and simultaneously to control for bias. METHODS AND ANALYSES: This case-control study is nested in a historical cohort and is designed to study vaccine effectiveness (VE) assessed by morbidity, mortality and anti-infective drug use. The cohort will comprise a representative sample of health insurance beneficiaries in France and will cover 10 consecutive epidemic seasons. It will include all patients reimbursed three separate times for drugs to treat diabetes. The first study of VE will use reasons for hospitalisation as the primary end point, and the second with the use of neuraminidase inhibitors and of antibiotics as the end points. A case will be defined as any person in the cohort reaching any end point at a given date. The case patient will be matched with the largest possible number of controls (individuals not reaching the end point by this date) according to the propensity score method with an optimal calliper width. A conditional logistic model will be used to estimate ORs to take into account both the matching and the repetition of measurements. The model will be applied separately during and outside of epidemic periods to estimate the residual confounding. ETHICS AND DISSEMINATION: The study has been approved by the French Commission on Individual Data Protection and Public Liberties (ref: AT/CPZ/SVT/JB/DP/CR05222O). The study's findings will be published in peer-reviewed journals and disseminated at international conferences and through social media.

[Effectiveness of preventive treatment by Influenzinum in the winter period against the onset of influenza-like illnesses]. / Efficacité d'un traitement préventif par Influenzinum en période hivernale contre la survenue d'un syndrome grippal.

AIM: In vitro Influenzinum induce a cellular change. We present the results of the first study examining the effectiveness of Influenzinum against influenza-like illnesses. METHOD: Retrospective cohort study during winter 2014-2015. After influenza epidemic, a self-assessment questionnaire was offered to patients presenting for a consultation. The primary endpoint was the declaration of an influenza-like illness. The exposed patients (treated by Influenzinum) were matched to two non-exposed patients (untreated) with a propensity score. A conditional logistic model expressed influenza-like illness risk reduction provided by the Influenzinum. RESULTS: The cohort included 3514 patients recruited from 46 general practitioners. After matching, the treated group (n=2041) and the untreated group (n=482) did not differ on variables collected. Influenzinum preventive therapy does not significantly alter the likelihood of influenza-like illness (adjusted odds ratio=0,91 [0,62 to 1,35], p=0,64). CONCLUSION: Influenzinum preventive therapy did not appear effective in preventing influenza-like illness.

Membership in a diabetes-care network and adherence to clinical practice guidelines for treating type 2 diabetes among general practitioners: A four-year follow-up.

OBJECTIVES: To assess whether private general practitioners (GPs) belonging to a diabetes-care network adhered more closely to clinical practice guidelines for diabetes care than GPs not in such a network, for all their patients with type 2 diabetes treated with medication (patients with diabetes), regardless of whether they received care through a network (that is, whether a halo effect occurred). RESEARCH DESIGN AND MEASURES: The study, based on health insurance reimbursement databases in southeastern France, included 468 GPs in two networks and 468 non-network GPs in the same geographical area, matched one-to-one by propensity scores. We followed up their patients with diabetes (n=22,808) from 2008 through 2011, conducting multivariate time-to-event analyses (Cox models) that took the matching design into account to evaluate time from inclusion until performance of the given number of each of six recommended examinations/tests. RESULTS: GPs belonging to a diabetes-care network adhered more closely to clinical practice guidelines but our result were slightly pronounced. Hazard ratios (HR) were significantly higher for patients of network GPs for the implementation of 3 HbA1C assays (HRa=1.13; [95%CI=1.10-1.16]), or 1 microalbuminuria assay (1.4 [1.35-1.45]); they were lower for LDL-cholesterol assays (1.04 [1.01-1.07]) and ophthalmological checkups (1.07 [1.04-1.10]), and not significant for creatinemia or cardiac monitoring. CONCLUSIONS: Network GPs had better diabetes monitoring practices for all their patients with diabetes than the other GPs, especially for the most diabetes-specific tests. Further research is needed in other settings to confirm the existence of this halo effect.

Bias in the measure of the effectiveness of seasonal influenza vaccination among diabetics.

BACKGROUND: The influenza virus is an important cause of morbidity and mortality for diabetics. The seasonal influenza vaccine's immunologic effectiveness is proven within the type 1 and type 2 diabetic populations, but the level of evidence is low. This article presents a systematic review for the bias in the measure of the effectiveness of seasonal influenza vaccination among diabetics. METHODS: Using systematic review methods, we searched three electronic databases for published literature (MEDLINE, EMBASE and the Cochrane Library) and two grey literature (SIGLE and NHS EED) databases, to identify studies published between 1997 and 2013, examining the effect of seasonal influenza vaccination, among diabetics, on any measure for influenza morbidity or mortality. RESULTS: 725 records were identified from the three databases and screening, short-listing was undertaken independently by two reviewers. After de-duplication, all records were screened by title and then abstract, and 34 short-listed records were reviewed in full, with 7 studies included: 4 cohort studies and 3 case-control studies, conducted in 7 countries. The most common outcome of interest in studies (n=4) was all-cause mortality among elderly diabetics (>65 years), with individual studies reporting reductions in risk of between 33% [95%CI: 4%-54%] and 68% [95%CI: 58%-75%]. We found only two studies for working-age adult diabetics: one reporting that vaccination prevented hospitalizations due to pneumonia or influenza (vaccine effectiveness [VE] 43%, [95%CI: 28%-54%]) and all-cause hospitalizations (VE: 28% [95%CI: 24%-32%]); and, another reporting no significant decrease in all-cause mortality for working-age adult diabetics. We have identified three major biases: the use of indirect health outcomes, a risk of selection bias (health-seeking bias), and no adjustment for participant pneumococcal vaccination status. The most recent included article finds that morbimortality is still lower during off-season influenza in both vaccinated and non-vaccinated diabetics, indicating important residual confounding. CONCLUSION: To date, the strength of evidence supporting the routine use of seasonal influenza vaccination is low for diabetics older than 65, and very low for working-age diabetics.

Factors associated with GPs' knowledge of their patients' socio-economic circumstances: a multilevel analysis.

BACKGROUND: To determine appropriate management for individual patients, GPs are supposed to use their knowledge of the patient's socio-economic circumstances. OBJECTIVE: To analyse factors associated with GPs' knowledge of these circumstances. METHODS: Observational survey of GPs who were internship supervisors in the Paris metropolitan area. Each of 52 volunteer GPs completed a self-administered questionnaire about their own characteristics and randomly selected 70 patients from their patient list. Their knowledge was analysed as the agreement between the patients' and GPs' responses to questions about the patients' socio-economic characteristics in questionnaires completed by both groups. The association between agreement and the GPs' characteristics was analysed with a multilevel model adjusted for age, sex and the duration of the GP-patient relationship. RESULTS: Agreement varied according to the socio-economic characteristics considered (from 51% to 90%) and between GPs. Globally, the GPs overestimated their patients' socio-economic level. GP characteristics associated with better agreement were sex (female), long consultations, the use of paper records or an automatic reminder system and participation in continuing medical education and in meetings to discuss difficult cases. CONCLUSION: Knowledge of some patient characteristics, such as their complementary health insurance coverage or perceived financial situation, should be improved because their overestimation may lead to care that is too expensive and thus result in the patients' abandonment of the treatment. Besides determining ways to help GPs to organize their work more effectively, it is important to study methods to help doctors identify their patients' social-economic circumstances more accurately in daily practice.

Social inequalities in early antidepressant discontinuation.

OBJECTIVE: This study aimed to test for social disparities in early discontinuation of antidepressant treatment and to explore associations with type of drug and composition of prescriber's clientele. METHODS: The cohort was 14,518 Marseille residents (ages 18-64 years) covered by the National Health Insurance Fund who had a new episode of antidepressant treatment (specifically, no prescription claim in the six months before the index claim) prescribed by a private general practitioner in 2008 or 2009. Factors associated with early discontinuation (prescription filled or refilled fewer than four times in the six months after the index claim) were analyzed with multilevel models that were adjusted for patient morbidity and number of consultations with private general practitioners and psychiatrists. Sensitivity analyses were conducted with different definitions of new treatment and early discontinuation. RESULTS: Low income, type of antidepressant (tricyclics versus selective serotonin reuptake inhibitors), and prescribers' clientele composition (specifically, a high proportion of socioeconomically disadvantaged patients) were independently associated with an increased risk of early antidepressant discontinuation. A significant interaction was found between low income and gender. Low-income patients were more likely than other patients to receive tricyclic antidepressants. CONCLUSIONS: These results add further evidence of inequalities in care for major depression and suggest that women are at greater disadvantage than men. Educational programs for general practitioners should focus on the risks of antidepressant discontinuation among disadvantaged patients. Enhancing therapeutic education of low-income patients may improve their treatment adherence.
