Gender awareness among general practitioners in France: a cross sectional study using the Nijmegen Gender Awareness in Medicine Scale (N-GAMS).

Gender is a key determinant of health and healthcare use. The question of whether physicians are aware of gender issues is important to avoid gender bias in medical practice. This study aimed to validate the Nijmegen Gender Awareness in Medicine Scale (N-GAMS) in a representative population of French general practitioners (GPs) and to analyze their gender sensitivity and the presence of gender stereotypes among them. The N-GAMS, already validated in medical students, measures gender awareness through 3 subscores: gender sensitivity (GS) and gender-role ideology towards patients (GRIP) and doctors (GRID) (gender stereotypes). After translation into French, it was distributed to 900 GPs. The scale was validated through exploratory factor analysis (EFA). Psychometric properties were tested. Multivariate linear regressions were conducted to explore the associations between GPs' characteristics and N-GAMS subscores. EFA identified 3 meaningful factors consistent with prior theory. Subscores exhibited good internal consistency. The main findings were that GRIP was significantly higher in older physicians, in male physicians, among those who less involved their patients in decisions, and those who were not training supervisors. For GRID, results were quite similar to those of GRIP. GS was significantly higher for physicians working in health centres or medical homes and for those with gynecological practices but lower when they less involved patients in medical decisions. This study suggests that it is necessary to teach gender issues not only in medical schools but also as part of continuing medical education.

Women's preferences for less active ectopic pregnancy treatment: A discrete choice experiment.

RESEARCH QUESTION: Shared decision-making has become a hallmark of quality care and is increasingly spotlighted in practice guidelines. Little is known about women's views for treatment of less active ectopic pregnancy. What are the preferences of women for less active ectopic pregnancy treatment-related attributes? DESIGN: A discrete choice model with 8 attributes depicting ectopic pregnancy treatment including varying levels of first-line treatment effectiveness, length of hospitalization, cost, length of sick leave, of convalescence, need for surgical management, for emergency care during convalescence and for tube removal was used. Childbearing aged women, i.e. those who might experience an ectopic pregnancy in the future, were recruited. They were asked to choose between hypothetical treatments in 18 choice tasks with different levels of all treatment attributes. A conditional logit McFadden's choice model was performed. The main outcome measure was preference weights for less active ectopic pregnancy treatment-related attributes. RESULTS: A total of 5770 observations from 178 women were analysed. The attributes displaying the highest marginal impacts on women's decisions included: higher rate of first-line treatment effectiveness, lower rate of tube removal, lower rate of surgical management, shorter length of hospitalization and, to a lesser extent, but still significant, shorter length of convalescence, absence of risk of emergency care during convalescence and lower cost. CONCLUSIONS: Trade-offs made by women between the attributes of less active ectopic pregnancy treatment suggest that no treatment option, either medical or surgical, is an obvious preferred option. These results encourage the promotion of shared decision-making.

Are breast cancer patients with suboptimal adherence to cardiovascular treatment more likely to discontinue adjuvant endocrine therapy? Competing risk survival analysis in a nationwide cohort of postmenopausal women.

BACKGROUND: High rates of discontinuation undermine the effectiveness of adjuvant endocrine therapy (AET) among hormone-receptive breast cancer patients. Patient prognosis also relies on the successful management of cardiovascular risk, which affects a high proportion of postmenopausal women. As with AET, adherence with cardiovascular drugs is suboptimal. We examined whether patient adherence with cardiovascular drugs was associated with the rate of AET discontinuation in a French nationwide claims database linked with hospitalisation data. METHODS: We identified postmenopausal women starting AET between 01/01/2016 and 31/12/2020 and taking at least two drugs for the primary prevention of cardiovascular disease (antihypertensive drugs, lipid-lowering drugs and platelet aggregation inhibitors) before AET initiation. Adherence was assessed for each drug class by computing the proportion of days covered. Women were categorised as fully adherent, partially adherent or fully non-adherent with their cardiovascular drug regimen based on whether they adhered with all, part or none of their drugs. AET discontinuation was defined as a 90-day gap in AET availability. Time to AET discontinuation according to levels of cardiovascular drug adherence was estimated using cumulative incidence curves, accounting for the competing risks of death and cancer recurrence. Multivariate cause-specific Cox regressions and Fine-and-Gray regressions were used to assess the relative hazards of AET discontinuation. RESULTS: In total, 32,075 women fit the inclusion criteria. Women who were fully adherent with their cardiovascular drugs had the lowest cumulative incidence of AET discontinuation at any point over the 5-year follow-up period. At 5 years, 40.2% of fully non-adherent women had discontinued AET compared with 33.5% of partially adherent women and 28.8% of fully adherent women. Both partial adherence and full non-adherence with cardiovascular drugs were predictors of AET discontinuation in the two models (cause-specific hazard ratios 1.16 [95% CI 1.10-1.22] and 1.49 [95% CI 1.39-1.58]; subdistribution hazard ratios 1.15 [95% CI 1.10-1.21] and 1.47 [95% CI 1.38-1.57]). CONCLUSION: Clinicians should be aware that patients who do not adhere with their entire cardiovascular drug regimen are also more likely to discontinue AET. This stresses the importance of integrated care, as suboptimal adherence with both treatment components poses a threat to achieving ideal patient outcomes.

Excess healthcare expenditure in adults treated for solid cancer in childhood: a cohort study in France.

BACKGROUND: Due to late effects, childhood cancer survivors (CCS) are more likely to have multiple chronic conditions than the general population. However, little is known about the economic burden of care of CCS in the long term. OBJECTIVES: To estimate excess healthcare expenditure for long-term CCS in France compared to the general population and to investigate the associated factors. METHODS: We included 5353 5-year solid CCS diagnosed before the age of 21 years before 2000 from the French CCS cohort and obtained a random reference sample from the general population for each CCS, matched on age, gender and region of residence. We used the French national health data system to estimate annual healthcare expenditure between 2011 and 2018 for CCS and the reference sample, and computed the excess as the net difference between CCS expenditure and the median expenditure of the reference sample. We used repeated-measures linear models to estimate associations between excess healthcare expenditure and CCS characteristics. RESULTS: Annual mean (95% CI) excess healthcare expenditure was €3920 (3539; 4301), mainly for hospitalization (39.6%) and pharmacy expenses (17%). Higher excess was significantly associated with having been treated before the 1990s and having survived a central nervous system tumor, whereas lower excess was associated with CCS who had not received treatment with radiotherapy. CONCLUSIONS: Of the variables that influence excess healthcare expenditure, a lever for action is the type of treatment administered. Future research should focus on addressing the long-term cost-effectiveness of new approaches, especially those related to radiotherapy.

Cost-effectiveness analysis of direct admission to acute geriatric unit versus admission after an emergency department visit for elderly patients.

BACKGROUND: Elderly individuals represent an increasing proportion of emergency department (ED) users. In the Greater Paris University Hospitals (APHP) direct-admission study, direct admission (DA) to an acute geriatric unit (AGU) was associated with a shorter hospital length of stay (LOS), lower post-acute care transfers, and lower risk of an ED return visit in the month following the AGU hospitalization compared with admission after an ED visit. Until now, no economic evaluation of DA has been available. METHODS: We aimed to evaluate the cost-effectiveness of DA to an AGU versus admission after an ED visit in elderly patients. This was conducted alongside the APHP direct-admission study which used electronic medical records and administrative claims data from the Greater Paris University Hospitals (APHP) Health Data Warehouse and involved 19 different AGUs. We included all patients ≥ 75 years old who were admitted to an AGU for more than 24 h between January 1, 2013 and December 31, 2018. The effectiveness criterion was the occurrence of ED return visit in the month following AGU hospitalization. We compared the costs of an AGU stay in the DA versus the ED visit group. The perspective was that of the payer. To characterise and summarize uncertainty, we used a non-parametric bootstrap resampling and constructed cost-effectiveness accessibility curves. RESULTS: At baseline, mean costs per patient were €5113 and €5131 in the DA and ED visit groups, respectively. ED return visit rates were 3.3% (n = 81) in the DA group and 3.9% (n = 160) in the ED group (p = 0.21). After bootstrap, the incremental cost-effectiveness ratio was €-4249 (95%CI= -66,001; +45,547) per ED return visit averted. Acceptability curves showed that DA could be considered a cost-effective intervention at a threshold of €-2405 per ED return visit avoided. CONCLUSION: The results of this cost-effectiveness analysis of DA to an AGU versus admission after an ED visit for elderly patients argues in favor of DA, which could help provide support for public decision making.

The Association Between Age and Admission to an Inappropriate Ward: A Cross-Sectional Survey in France.

Half of elderly patient hospitalizations are preceded by an emergency department (ED) visit. Hospitalization in inappropriate wards (IWs), which is more frequent in case of ED overcrowding and high hospital occupancy, leads to increased morbidity. Elderly individuals are the most exposed to these negative health care outcomes. Based on a nationwide cross-sectional survey involving all EDs in France, the aim of this study was to explore whether age was associated with admission to an IW after visiting an ED. Among the 4384 patients admitted in a medical ward, 4065 were admitted in the same hospital where the ED was located, among which 17.7% were admitted to an IW. Older age was associated with an increased likelihood of being admitted to an IW (OR = 1.39; 95% CI = 1.02-1.90 for patients aged 85 years and older and OR = 1.40; 95% CI = 1.02-1.91 for patients aged 75-84 years, compared with those under 45 years). ED visits during peak periods and cardio-pulmonary presenting complaint were also associated with an increased likelihood of admission to an IW. Despite their higher vulnerability, elderly patients are more likely to be admitted to an IW than younger patients. This result reinforces the need for special attention to be given to the hospitalization of this fragile population.

Trends in clomiphene citrate and gonadotropins use in women with infertility between 2010 and 2017: A population-based study in France.

PURPOSE: To describe temporal trends and assess factors associated with changes in the prescription of clomiphene citrate and gonadotropins between 2010 and 2017 in women with infertility aged 18-50 from metropolitan France. METHODS: 6321 prevalent women from a representative sample of the national medico-administrative database were identified. We performed a Cochran-Armitage trend test and calculated the rate ratios. A Poisson regression was used to derive the incidence rate ratios, for each treatment class. RESULTS: The prevalence rate and incidence rate of clomiphene citrate use significantly decreased by 20% (RR 0.80: 95% CI 0.71-0.90) and 23% (RR 0.77: 95% CI 0.66-0.89), respectively. Its initiation was higher in all age groups compared to the reference (18-24 years), with a downward gradient. It was also higher when the density of gynaecologists was higher and in disadvantaged areas. The prevalence rate and incidence rate of gonadotropin use increased by 11% (RR 1.11: 95% CI 1.01-1.22) and 33% (RR 1.33: 95% CI 1.14-1.55) respectively. Gonadotropin initiation was highest in the 31-35 age group, but it was also higher in the 25-30 and 36-40 age groups at a similar level (reference 18-24 years). Its initiation was higher when the density of gynaecologists was higher, but not associated with social deprivation. CONCLUSION: Our results showed an increase in gonadotropin use for infertility treatment in France during the 2010-2017 period and a decrease in clomiphene citrate use. Further work should be undertaken to analyse the use of these drugs in relation to women's care pathways.

Long-term hospitalisations in survivors of paediatric solid tumours in France.

The late effects of treatments for childhood cancers may lead to severe and multiple health conditions requiring hospitalisation. We aimed to estimate the hospitalisation rate among childhood cancer survivors (CCS) in France, to compare them with the general population and to investigate the associated factors. We matched total of 5439 5-year solid CCS diagnosed before the age of 21 between 1945 and 2000 by sex, birth year and region of residence to 386,073 individuals of the French general population. After linkage with the national hospital discharge database, we estimated the relative hospitalisation rate (RHR), the absolute excess risks (AERs) and the relative bed-day ratio (RBDR) during 2006-2018. We used generalised linear models to estimate associations between hospitalisation and survivor characteristics. Overall, the RHR was 2.49 (95% confidence interval [CI] 2.46-2.52) and the RBDR was 3.49 (95% CI 3.46-3.51). We found that neoplasm-related hospitalisations had the highest AER (105.8 per 1000 person-years), followed by genitourinary system diseases (34.4 per 1000 person-years) and cardiovascular diseases (19.2 per 1000 person-years). In adjusted analysis, CCS treated with chemotherapy (risk ratio [RR] 1.62, 95% CI 1.53-1.70), radiotherapy (RR 2.11, 95% CI 1.99-2.24) or both (RR 2.59, 95% CI 2.46-2.73) had a higher risk of hospitalisation than the ones who had not received any of these treatments. CCS treated during the past decades by chemotherapy and/or radiotherapy now had a higher hospitalisation risk for all main categories of diagnosis than the general population. Prevention strategies and medical surveillance programmes may promote a long-term decrease in the hospitalisation rate among CSS.

Defining a risk-adjustment formula for the introduction of population-based payments for primary care in France.

Novel risk-adjusted payment models for financing primary care are currently being experimented in France. In particular, pilot schemes including shared-savings contracts or prospectively allocated capitation payments are implemented for voluntary primary care structures. Such payment mechanisms require defining a risk-adjustment formula to accurately estimate expected expenditure while maintaining appropriate efficiency incentives. We used nationwide data from the French national health data system (SNDS) to compare the performance of different prospective models for total and outpatient expenditure prediction among more than 8 million individuals aged 65 or more and their application at an aggregate level. We focused on the characterization of morbidity status and on the contextual characteristics to include in the formula. We proposed a set of practical routinely available predictors with fair performance for patient-level expenditure prediction (explaining 32% of variance) that could be used to risk-adjust prospective payments in the French setting. Morbidity information was the strongest predictor but could lead to considerable error in predicted expenditures if introduced as independent binary variables in multiplicative models, underlining the importance of summary morbidity measures and of using the appropriate metric to assess model performance. Distribution of aggregate-level allocations was greatly modified according to the method to account for contextual characteristics. Our work informs the introduction of risk-adjusted models in France and underlines efficiency and fairness issues raised.

Health care expenditures among long-term survivors of pediatric solid tumors: Results from the French Childhood Cancer Survivor Study (FCCSS) and the French network of cancer registries (FRANCIM).

BACKGROUND: Childhood cancer survivors (CCS) may require lifelong medical care due to late effects of cancer treatments. Little is known about of their healthcare utilization and expenditures at long-term especially in publicly funded health care system. We aim to estimate and describe the health care expenditures among long-term CCS in France. METHODS: A total of 5319 five-year solid CCS diagnosed before the age of 21 between 1945 and 2000 in France were identified in the French Childhood Cancer Survivors Study cohort (FCCSS) and the French cancer registry. Information about health care expenditure was taken from the French national health data system between 2011 and 2016, and was described according to survivors' characteristics. Generalized linear models were used to determine associations between health care expenditures and survivors' characteristics. RESULTS: Mean annual amount of healthcare expenditures was € 4,255. Expenditures on hospitalizations and pharmacy represents 60% of total expenditures. Mean annual of healthcare expenditures were higher at increasing age, among women survivors (€ 4,795 vs € 3,814 in men) and in central nervous system (CNS) tumor survivors (€ 7,116 vs € 3,366 in lymphoma and € 3,363 in other solid tumor survivors). CONCLUSIONS: Childhood cancer survivorship is associated with a substantial economic burden in France. We found that female gender and CNS primary cancer were associated with increased healthcare expenditures.

Risk-seeking attitude in health and safety domain is associated with continuous positive airway pressure discontinuation in patients with obstructive sleep apnea-a multicenter prospective cohort study.

STUDY OBJECTIVES: Many studies have already looked at factors that may influence adherence to continuous positive airway pressure (CPAP) (severity of obstructive sleep apnea (OSA), patients' age, technical aspects, socioeconomic factors, living conditions, psychological factors). Although it has been shown that individuals' preference for risky behaviors in daily life can influence the use of care or adherence to drug therapies in care settings, this has never been tested in OSA. This study aims to analyze the association between risk attitude in the health/safety domain and CPAP discontinuation in a cohort of OSA patients. METHODS: In a prospective multicenter cohort study nested within the IRSR sleep cohort, consecutive patients who were prescribed CPAP were monitored for at least 6 months. In addition to the data usually collected in the IRSR sleep cohort at baseline, patients also completed a risk-taking questionnaire using the Domain-Specific Risk-Taking (DOSPERT) scale. Cox's proportional hazards regression was used to model the risk of CPAP discontinuation as a function of a linear combination of variables hypothetically related to this risk including health risk attitude. RESULTS: Of the 489 patients under CPAP, 12.1% (n = 59) were risk-seeking, 87.9% (n = 430) were risk-neutral, and none were risk-averse. Cox's model indicated that a risk-seeking attitude (p = 0.04) and an AHI <30 (p < 0.01) were significantly associated with CPAP discontinuation. CONCLUSIONS: Patients with risk-seeking behaviors in daily life have been shown to be more likely to discontinue CPAP. The DOSPERT scale can be a useful tool for screening this specific group of patients in clinical practice.

Patient stratification for risk of readmission due to heart failure by using nationwide administrative data.

BACKGROUND: Identifying patients with heart failure (HF) who are most at risk of readmission permits targeting adapted interventions. The use of administrative data enables regulators to support the implementation of such interventions. METHODS AND RESULTS: In a French nationwide cohort of patients aged 65 years or older, surviving an index hospitalization for HF in 2015 (N = 70,657), we studied HF readmission predictors available in administrative data, distinguishing HF severity from overall morbidity and taking into account the competing mortality risk, over a 1-year follow-up period. We also computed cumulative incidences and daily rates of HF readmission for patient groups defined according to HF severity and overall morbidity. Of the patients, 31.8% (n = 22,475) were readmitted at least once for HF, and 17.6% (n = 12,416) died without any readmission for HF. HF severity and overall morbidity were the strongest readmission predictors were the strongest readmission predictors (subdistribution hazard ratios 2.66 [95% CI: 2.52-2.81] and 1.37 [1.30-1.45], respectively, when comparing extreme categories). Overall morbidity and age were more strongly associated with the rate of death without HF readmission (cause-specific hazard ratios). The difference in observed HF readmission between patient risk groups was approximately 40% (21.9%, n = 2144/9,786 vs 60.4%, n = 618/1023). CONCLUSIONS: Segmentation of HF patients into readmission risk groups is possible by using administrative data, and it enables the targeting of preventive interventions.

A top 5 list for French general practice.

BACKGROUND: Medical overuse is an issue that has recently gained attention. The "Choosing Wisely" campaign invited each specialty in each country to create its own top five lists of care procedures with a negative benefit-risk balance to promote dialogue between patients and physicians. This study aims to create such a list for French general practice. METHODS: A panel of general practitioners (GPs) suggested care procedures that they felt ought to be prescribed less. Using the Delphi method, a short list of those suggestions was selected. Systematic literature reviews were performed for each item on the short list. The results were presented to the panel to assist with the final selection of the top five list. RESULTS: The panel included 40 GPs. The list includes: i/ antibiotics prescription for acute bronchitis, nasopharyngitis, otitis media with effusion, or uncomplicated influenza, ii/ systematic prostate specific antigen testing in men older than 50, iii/ prescription of cholinesterase inhibitors for mild cognitive impairment and for Alzheimer's disease and memantine for Alzheimer's disease, iv/ statins prescription in primary prevention of cardio-vascular risk in older patients, and v/ benzodiazepine or benzodiazepine-like agents prescription for generalised anxiety, insomnia, and for all indications in older patients. CONCLUSIONS: This study resulted in a French top five list in general practice using a panel of GPs. All the items selected have a negative risk-benefit balance and are frequently prescribed by French general practitioners. This list differs from other top five lists for general practice, reflecting the local medical culture.

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.

Measuring public preferences in France for potential consequences stemming from re-allocation of healthcare resources.

When deciding which new programme to implement and where the additional resources, if needed, will come from, the decision makers need to accommodate the uncertainty of the potential changes in population health and medical expenditures that can occur. They also need to determine the value of these potential changes. The objective of this study is to identify a public valuation function measuring how the public values changes in population health and medical expenditures when healthcare resources are re-allocated. We report the results of a choice experiment conducted in March 2016 in a representative sample of the population living in France (N = 1008). The main results indicate that the public is more sensitive to changes in population health than changes in the level of medical expenditures. There is a non-linear valuation of these changes with evidence of asymmetric preferences and non-constant marginal sensitivity. The public gives 1.4 times more weight to decrease in population health than for the same-size increase. The public becomes less sensitive to marginal changes in population health as the level of changes increases. In a simulation study of 5000 resource allocation decisions, we show that non-linearities in public valuation of population health and medical expenditures matters. The linear and non-linear public valuation functions were associated with respectively 50.1% and 28.1% of situations of acceptable outcome of the reallocation of resources. The level of agreement between these two functions was moderate with a Kappa coefficient of 0.56, and the probability of agreement was mainly driven by the distribution of net changes in population health. This study provides a method and an estimation of a public valuation function that describes the preferences (or values attributed) for every potential outcome stemming from the reallocation of healthcare resources. The results show the importance of measuring such function rather than assuming one.

Préférences des femmes vis-à-vis du dépistage du cancer du sein.

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.

Measuring Public Preferences for Health Outcomes and Expenditures in a Context of Healthcare Resource Re-Allocation.

BACKGROUND: The final outcome of any resource allocation decision in healthcare cannot be determined in advance. Thus, decision makers, in deciding which new program to implement (or not), need to accommodate the uncertainty of different potential outcomes (i.e., change in both health and costs) that can occur, the size and nature (i.e., 'bad' or 'good') of these outcomes, and how they are being valued. Using the decision-making plane, which explicitly incorporates opportunity costs and relaxes the assumptions of perfect divisibility and constant returns to scale of the cost-effectiveness plane, all the potential outcomes of each resource allocation decision can be described. OBJECTIVE: In this study, we describe the development and testing of an instrument, using a discrete choice experiment methodology, allowing the measurement of public preferences for potential outcomes falling in different quadrants of the decision-making plane. METHOD: In a sample of 200 participants providing 4200 observations, we compared four versions of the preference-elicitation instrument using a range of indicators. RESULTS: We identified one version that was well accepted by the participants and with good measurement properties. CONCLUSION: This validated instrument can now be used in a larger representative sample to study the preferences of the public for potential outcomes stemming from re-allocation of healthcare resources.

General practitioner consultation after a visit to the emergency department: an observational study.

BACKGROUND: Some studies have demonstrated an association between poor continuity of care, high likelihood of 'inappropriate' use of emergency departments (EDs) and avoidable hospitalization. However, we lack data concerning primary care use after an ED visit. OBJECTIVE: Identify the determinants of a visit to the general practitioner (GP) after an ED visit.Methods. DESIGN: Observational study (single-centre cohort). SETTING: One emergency department in Paris, France. SUBJECTS: All adult patients who presented at the ED and were discharged. MAIN OUTCOME MEASURE: We collected data by the use of a standardized questionnaire, patients' medical records and a telephonic follow-up. Descriptive analyses were performed to compare individuals with and without a GP. Then, for those with a GP, multivariate logistic regression was used to identify the determinants of the GP consultation. RESULTS: We included 243 patients (mean age 45 years [±19]); 211 (87%) reported having a GP. Among those who reported having a GP, 52% had consulted their GP after the ED visit. Not having a GP was associated with young age, not having complementary health insurance coverage, and being single. GP consultation was associated with increasing age [adjusted odds ratios (aOR) = 1.03], poor self-reported health status (aOR = 2.25), medical complaints versus traumatic injuries (aOR = 2.24) and prescription for sick note (aOR = 5.74). CONCLUSION: Not having a GP was associated with factors of social vulnerability such as not having complementary health insurance coverage. For patients with a GP, consultation in the month after an ED visit seems appropriate, because it was associated with poor health status and medical complaints.
