Generalized pustular psoriasis: A nationwide population-based study using the National Health Data System in France.

BACKGROUND: GPP is a rare, chronic, neutrophilic skin disease, with limited real-world data characterizing patients with flares and the impact of flares on disease progression and morbidity. OBJECTIVE: Describe the clinical characteristics of patients with GPP, comorbidities, disease epidemiology and frequency and severity of flares, and compare patients with GPP with a matched severe psoriasis population. METHODS: In this population-based real-world cohort study an algorithm was developed to identify patients with GPP flares. Three cohorts were identified using the Système National des Données de Santé (SNDS) database covering almost the entire French population; a prevalent cohort (2010-2018), an incident cohort (2012-2015). A severe psoriasis cohort was compared with the GPP incident cohort using propensity score matching. RESULTS: The prevalent and incident cohorts comprised 4195 and 1842 patients, respectively. In both cohorts, mean age was 58 years; 53% were male. Comorbidities were significantly more common in the incident cohort versus matched psoriasis cohort, respectively, including hypertension (44% vs. 26%), ischaemic heart disease (26% vs. 18%) and hyperlipidaemia (25% vs. 15%). In the incident cohort, the flare rate was 0.1 flares/person-year and 0.4 flares/person-year among the 569 out of 1842 patients hospitalized with flares. These patients had a mean (±SD) stay of 11.6 ± 10.4 days; 25% were admitted to the intensive care unit. In 2017, the cumulative incidence and cumulative GPP age-sex standardized prevalence were 7.1 and 45.2 per million, respectively. CONCLUSIONS: Patients with GPP had a distinct comorbidity profile compared to patients with severe psoriasis, and GPP flares were associated with long hospitalizations.

Estimates of epidemiology, mortality and disease burden associated with progressive fibrosing interstitial lung disease in France (the PROGRESS study).

BACKGROUND: There is a paucity of data on the epidemiology, survival estimates and healthcare resource utilisation and associated costs of patients with progressive fibrosing interstitial lung disease (PF-ILD) in France. An algorithm for extracting claims data was developed to indirectly identify and describe patients with PF-ILD in the French national administrative healthcare database. METHODS: The French healthcare database, the Système National des Données de Santé (SNDS), includes data related to ambulatory care, hospitalisations and death for 98.8% of the population. In this study, algorithms based on age, diagnosis and healthcare consumption were created to identify adult patients with PF-ILD other than idiopathic pulmonary fibrosis between 2010 and 2017. Incidence, prevalence, survival estimates, clinical features and healthcare resource usage and costs were described among patients with PF-ILD. RESULTS: We identified a total of 14,413 patients with PF-ILD. Almost half of them (48.1%) were female and the mean (± standard deviation) age was 68.4 (± 15.0) years. Between 2010 and 2017, the estimated incidence of PF-ILD ranged from 4.0 to 4.7/100,000 person-years and the estimated prevalence from 6.6 to 19.4/100,000 persons. The main diagnostic categories represented were exposure-related ILD other than hypersensitivity pneumonitis (n = 3486; 24.2%), idiopathic interstitial pneumonia (n = 3113; 21.6%) and rheumatoid arthritis-associated ILD (n = 2521; 17.5%). Median overall survival using Kaplan-Meier estimation was 3.7 years from the start of progression. During the study, 95.2% of patients had ≥ 1 hospitalisation for respiratory care and 34.3% were hospitalised in an intensive care unit. The median (interquartile range) total specific cost per patient during the follow-up period was €25,613 (10,622-54,287) and the median annual cost per patient was €18,362 (6856-52,026), of which €11,784 (3003-42,097) was related to hospitalisations. Limitations included the retrospective design and identification of cases through an algorithm in the absence of chest high-resolution computed tomography scans and pulmonary function tests. CONCLUSIONS: This large, real-world, longitudinal study provides important insights into the characteristics, epidemiology and healthcare resource utilisation and costs associated with PF-ILD in France using a comprehensive and exhaustive database, and provides vital evidence that PF-ILD represents a high burden on both patients and healthcare services.

Three-year clinical outcomes in patients with rheumatoid arthritis treated with certolizumab pegol: results from the observational ECLAIR study.

OBJECTIVES: To describe the long-term effectiveness and safety of certolizumab pegol in patients with moderate-to-severe rheumatoid arthritis (RA) in a real-world setting in France. METHODS: ECLAIR was a 3-year longitudinal, prospective, observational, multicentre study. The primary objective was to describe the EULAR response after 1 year of certolizumab pegol treatment. Other endpoints included DAS28, clinical disease activity index, health assessment questionnaire disability index, fatigue assessment scale, patient's assessment of arthritis pain, patient and physician global assessments of disease activity, patient quality of life, and long-term safety. RESULTS: A total of 792 patients were enrolled, of whom 776 comprised the safety set, and 733 the full analysis set. In the full analysis set, 559, 469 and 430 patients had a 12-, 24- and 36-month visit, respectively. This included 378, 296 and 246 patients still receiving certolizumab pegol at these visits. The percentage of EULAR responders was 75.3% (305/405 patients with an available EULAR response) at 12, 76.5% (261/341) at 24, and 79.6% (226/284) at 36 months. Among those still receiving certolizumab pegol, the percentage of EULAR responders was 81.7% (237/290) at 12, 81.1% (185/228) at 24, and 87.3% (158/181) at 36 months. Sustained improvements were observed in other effectiveness outcomes. Overall, 45.1% (350/776) of patients experienced 776 adverse drug reactions. No new safety signals were identified. CONCLUSIONS: This is the first prospective, observational study of an anti-TNF treatment in France. The results confirm the effectiveness and safety profile of certolizumab pegol treatment in patients with RA in a real-world setting.

Incidence of acute intussusception among infants in eastern France: results of the EPIstudy trial.

The incidence of intussusception in infants varies around the world. The epidemiology of intussusception in France has never been prospectively studied. We performed a prospective observational study with systematic inclusion of all infants aged <1 year with suspected intussusception admitted to the emergency departments of the hospitals in the eastern region of France (98,000 live births per year), from 4/1/2008 to 3/31/2012. Cases were classified using the Brighton Collaboration classification. In total, 185 infants with suspected intussusception were included of which 169 were idiopathic intussusception. Among these 169 cases, 115 (68%) were classed as Brighton level 1 (confirmed cases). Overall incidence of intussusception over the 4 years of the study was 29.8 (95% CI 24.6-35.7) cases per 100,000 live births for level 1 and 37.5 (95% CI 31.7-44.2) cases per 100,000 live births for all cases (levels 1-4). Annual incidence rates of level 1 intussusception were as follows: 44 (95% CI 31.9-59.3), 30.9 (20.9-44.2), 21.7 (13.4-33.2) and 22.1 (13.7-33.8) per 100,000 live births in the 1st, 2nd, 3rd and 4th study years, respectively. CONCLUSION: The incidence rate of intussusception in the eastern part of France is comparable to that of other European countries. There was a significant trend towards a decrease in the incidence of intussusception. What is known • Intussusception is the most frequent causes of intestinal obstruction in infants and young children. Overall incidence of intussusception in infants aged <1 year varies widely around the world. No specific epidemiological studies have not been conducted in France on intussusception. What is new: • This prospective and multicenter study provides important information about the epidemiology of intussusception in infants in France over a period of 4 years.

Pilot non dialysis chronic renal insufficiency study (P-ND-CRIS): a pilot study of an open prospective hospital-based French cohort.

BACKGROUND: Before establishing a prospective cohort, an initial pilot study is recommended. However, there are no precise guidelines on this subject. This paper reports the findings of a French regional pilot study carried out in three nephrology departments, before realizing a major prospective Non Dialysis Chronic Renal Insufficiency study (ND-CRIS). METHODS: We carried out an internal pilot study. The objectives of this pilot study were to validate the feasibility (regulatory approval, providing patients with information, availability of variables, refusal rate of eligible patients) and quality criteria (missing data, rate of patients lost to follow-up, characteristics of the patients included and non-included eligible patients, quality control of the data gathered) and estimate the human resources necessary (number of clinical research associates required). RESULTS: The authorizations obtained (CCTIRS - CNIL) and the contracts signed with hospitals have fulfilled the regulatory requirements. After validating the information on the study provided to patients, 1849 of them were included in three centres (university hospital, intercommunal hospital, town hospital) between April 2012 and September 2015. The low refusal rate (51 patients) and the characteristics of non-included patients have confirmed the benefit for patients of participating in the study and provide evidence of the feasibility and representativeness of the population studied. The lack of missing data on the variables studied, the quality of the data analyzed and the low number of patients lost to follow-up are evidence of the quality of the study. By taking into account the time spent by CRAs to enter data and to travel, as well as the annual patient numbers in each hospital, we estimate that five CRAs will be required in total. CONCLUSION: With no specific guidelines on how to realize a pilot study before implementing a major prospective cohort, we considered it pertinent to report our experience of P-ND-CRIS. This experience confirms that i) feasibility, ii) quality of data and iii) evaluating the resources required must be validated before carrying out a large prospective cohort study such as ND-CRIS.

The Non-Dialysis Chronic Renal Insufficiency study (ND-CRIS): an open prospective hospital-based cohort study in France.

BACKGROUND: Chronic kidney disease (CKD) amounts to a heavy burden for health services. There is no long-running epidemiological tool for CKD before dialysis. We here present the protocol for a cohort of patients with "non-dialysis" CKD receiving care in the Bourgogne-Franche-Comté region of France. The aim of this cohort was to periodically describe the characteristics of patients included and their care provision, to analyse evolution in care and patients' kidney function outcomes. METHODS: The ND-CRIS cohort is prevalent and incident. Patients are included in the cohort if over 18, with a glomerula filtration rate (GFR) <60 ml/min/1.73 m2, non-dialysed, informed on the research and not having opposed it, and followed by a nephrologist in one of the 9 centres in the region, (3 pilot centres joined by 6 others in 2015). All the patients are followed up, with varying time lapses according to the degree of GFR deterioration. Data is collected by clinical research assistants (CRAs) using a dedicated computerised case-report form (CRF). Professional practices are assessed using indicators defined by the French Health Authority. The follow-up of patients included should enable assessment of the evolution of their GFR and co-morbidities. The periodic descriptions should give insight into evolution in epidemiological terms. DISCUSSION: The ND-CRIS meets a need in epidemiological tools in France for CKD. The cohort does claim to be representative, of ND-CKD patients receiving care from nephrologists. The open and incident nature of the cohort and the number of patients included in the ND-CRIS should provide answers to questions that cannot be answered by smaller solely prevalent cohorts. The numbers of patients included over the study period (2391 patients in 3 centres in 3 years) suggests that the figure of 5000 patients should be reached by 2017. The participation of nephrologists and the rate of inclusions point to the feasibility of the implementation of this cohort. Beyond the information to be found in the CRFs, this cohort should also enable ad hoc studies, in particular in the area of pharmaco-epidemiology, and it could later serve as a research platform and as a public health surveillance tool.

Homeopathic medical practice for anxiety and depression in primary care: the EPI3 cohort study.

BACKGROUND: The purpose of the study was to compare utilization of conventional psychotropic drugs among patients seeking care for anxiety and depression disorders (ADDs) from general practitioners (GPs) who strictly prescribe conventional medicines (GP-CM), regularly prescribe homeopathy in a mixed practice (GP-Mx), or are certified homeopathic GPs (GP-Ho). METHODS: This was one of three epidemiological cohort studies (EPI3) on general practice in France, which included GPs and their patients consulting for ADDs (scoring 9 or more in the Hospital Anxiety and Depression Scale, HADS). Information on all medication utilization was obtained by a standardised telephone interview at inclusion, 1, 3 and 12 months. RESULTS: Of 1562 eligible patients consulting for ADDs, 710 (45.5 %) agreed to participate. Adjusted multivariate analyses showed that GP-Ho and GP-Mx patients were less likely to use psychotropic drugs over 12 months, with Odds ratio (OR) = 0.29; 95 % confidence interval (CI): 0.19 to 0.44, and OR = 0.62; 95 % CI: 0.41 to 0.94 respectively, compared to GP-CM patients. The rate of clinical improvement (HADS <9) was marginally superior for the GP-Ho group as compared to the GP-CM group (OR = 1.70; 95 % CI: 1.00 to 2.87), but not for the GP-Mx group (OR = 1.49; 95 % CI: 0.89 to 2.50). CONCLUSIONS: Patients with ADD, who chose to consult GPs prescribing homeopathy reported less use of psychotropic drugs, and were marginally more likely to experience clinical improvement, than patients managed with conventional care. Results may reflect differences in physicians' management and patients' preferences as well as statistical regression to the mean.

Utilization of psychotropic drugs by patients consulting for sleeping disorders in homeopathic and conventional primary care settings: the EPI3 cohort study.

BACKGROUND: Utilization of sedative hypnotic drugs for sleeping disorders (SD) raises concerns, particularly among older people. This study compared utilization of conventional psychotropic drugs for SD among patients seeking care from general practitioners (GPs) who strictly prescribe conventional medications (GP-CM), regularly prescribe homeopathy in a mixed practice (GP-Mx), or are certified homeopathic GPs (GP-Ho). METHODS: This was a French population-based cohort study of GPs and their patients consulting for SD, informed through the Pittsburgh sleep quality index (PSQI) questionnaire. Information on psychotropic drugs utilization was obtained from a standardized telephone interview at inclusion, one, three and 12 months. RESULTS: 346 patients consulting for SD were included. Patients in the GP-Ho group experienced more often severe SD (41.3%) than patients in the GP-CM group (24.3%). Adjusted multivariate analyses showed that patients who chose to be managed by GP-Ho were less likely to use psychotropic drugs over 12 months as opposed to the GP-CM group, with Odds ratio (OR) = 0.25; 95% confidence interval (CI): 0.14 to 0.42. Patients in the GP-Mx group also used less psychotropic drugs but the result was not statistically significant (OR = 0.67; 95% CI: 0.39-1.16). Rates of clinical improvement of the SD did not differ between groups. CONCLUSIONS: Patients with SD who chose to consult GPs certified in homeopathy consumed less psychotropic drugs and had a similar evolution of their condition to patients treated with conventional medical management. This result may translate in a net advantage with reduction of adverse events related to psychotropic drugs.

Assessment and non-clinical impact of medical devices.

Medical devices (MDs) cover a wide variety of products. They accompany changes in medical practice in step with technology innovations. Innovations in the field of MDs can improve the conditions of use of health technology and/or modify the organisation of care beyond the strict diagnostic or therapeutic benefit for the patients. However, these non purely clinical criteria seem to be only rarely documented or taken into account in the assessment of MDs during reimbursement decisions at national level or for formulary listing by hospitals even though multidimensional models for the assessment of health technologies have been developed that take into account the views of all stakeholders in the healthcare system In this article, after summarising the background concerning the assessment of health technologies in France, a definition of non-clinical criteria for the assessment of MDs is proposed and a decision tree for the assessment of MDs is described. Future lines of approach are proposed as a conclusion.

Characteristics of patients consulting their regular primary care physician according to their prescribing preferences for homeopathy and complementary medicine.

BACKGROUND: Homeopathic care has not been well documented in terms of its impact on patients' utilization of drugs or other complementary and alternative medicines (CAM). The objective of this study was to describe and compare patients who visit physicians in general practice (GPs) who prescribe only conventional medicines (GP-CM), regularly prescribe homeopathy within a mixed practice (GP-Mx), or are certified homeopathic GPs (GP-Ho). MATERIAL AND METHODS: The EPI3-LASER study was a nationwide observational survey of a representative sample of GPs and their patients from across France. Physicians recorded their diagnoses and prescriptions on participating patients who completed a self-questionnaire on socio-demographics, lifestyle, quality of life Short Form 12 (SF-12) and the complementary and alternative medicine beliefs inventory (CAMBI). RESULTS: A total of 6379 patients (participation rate 73.1%) recruited from 804 GP practices participated in this survey. Patients attending a GP-Ho were slightly more often female with higher education than in the GP-CM group and had markedly healthier lifestyle. They did not differ greatly in their comorbidities or quality of life but exhibited large differences in their beliefs in holistic medicine and natural treatments, and in their attitude toward participating to their own care. Similar but less striking observations were made in patients of the GP-Mx group. CONCLUSION: Patients seeking care with a homeopathic GP did not differ greatly in their socio-demographic characteristics but more so by their healthier lifestyle and positive attitude toward CAM. Further research is needed to explore the directionality of those associations and to assess the potential economic benefits of homeopathic management in primary care.

Better defining target populations for drugs with a view to reimbursement.

Reimbursement of drugs by public or private insurance systems is increasingly problematic, including in supposedly "rich" countries. There is an international consensus to consider the benefit of a Health technology assessment to clarify decisions on reimbursement by the collectivity, and this includes taking account of the target population of the new drug. The authors debate about the urgent need of a better quantification of the target population, which must include a qualitative description of this target population and a scientific extrapolation of the target population, which is certainly the most challenging problem.

Homeopathy as Praxis: Integration of Homeopathy as Supportive Care into Daily Life in Early Breast Cancer Patients.

INTRODUCTION: Homeopathy is one of most widely used non-conventional supportive care methods used by women with breast cancer. This article aims to describe the routines and practices related to homeopathy as supportive care used by women with non-metastatic breast cancer in France. METHODS: This qualitative study used Grounded Theory. Participants were women with early breast cancer and healthcare professionals (General Practitioner homeopaths & oncologists). Inclusion depended on specific criteria and the aim of theoretical sampling until data saturation. Data were collected through individual semi-structured interviews and focus groups following evolving topic guides. Transcribed interviews underwent in-depth thematic analysis. Inclusion, interviewing, transcription and coding occurred iteratively. Data was reported according to COREQ guidelines. RESULTS: The therapeutic agency of homeopathy was distributed to different actors and ritualized material activities highly involving the patient. The choice of remedy was mostly delegated by patients to General Practitioner homeopaths (GPH) during consultations. Individualization, that is to say adaptation to the patient, differed from other modes of access to homeopathy (self-medication and oncologists). Self-medication was mostly limited to known products in a limited time frame. However, we identified a supported self-medication using trusted homeopathic protocols. Following homeopathic prescriptions involves a high level of commitment on behalf of the patient and follows different rules for homeopathy intake. This knowledge was either acquired earlier for users or discovered along breast cancer treatment for non-users. Taking homeopathy involved small daily actions for intake of different products at different times of the day. New users used strategies to ease the integration of homeopathy into their daily life. The stance toward such rules differed among patients. Some followed rules to optimize their effects while others simplified the rules and took those rituals as part of homeopathy benefits. CONCLUSION: Homeopathy as supportive care in breast cancer is distributed toward different actors and ritualized activities. Homeopathy is a supported practice where GPH played a role in the prescription. Health Literacy in homeopathy played a role to ease its integration into daily life and identify the potential benefits. The high involvement of patients in their homeopathic treatment is a form of treatment reappropriation and empowerment.

A cohort study of therapeutic prescriptions after the end of phytotherapy drug reimbursement by French Social Security.

PURPOSE: The reimbursement of phytotherapy drugs for the treatment of mild anxiety and insomnia ended in March 2006 in France. The aim of this study is to investigate the short-term impact of stopping phytotherapy reimbursement. METHODS: We monitored the prescriptions of 27,422 patients who received hypnotic and sedative phytotherapy drug treatment at least once in the 12 months preceding the end of reimbursement and made contact with their prescribing physician at least once in the following 12 months. A control cohort was recruited from patients fulfilling the same inclusion criteria in the 24 months before de-reimbursement and their prescriptions in the following 12 months were monitored. The impact of the end of reimbursement is estimated comparing prescription switches in these cohorts. RESULTS: Before the end of reimbursement, 7684 (28%) patients being prescribed delisted phytotherapy drugs had the relevant drug marketing authorization approval (DMAA) indications. Co-prescriptions of hypnotic and sedative drugs concerned 40% of patients. Of the 4646 DMAA patients exclusively prescribed phytotherapy, 640 (14%) switched to hypnotic or sedative drugs only after the end of reimbursement, 3266 (70%) stopped all treatments and 740 (16%) carried on with a non-reimbursed phytotherapy prescription. When compared to the control cohort, patients exposed to de-reimbursement were more likely to switch to psychotropic drugs (OR = 1.46). CONCLUSIONS: Ending the reimbursement of common drugs on the basis of insufficient evidence regarding their effectiveness or the low level of severity of their target pathologies should be accompanied by information or advice to prescribing health care actors.

Impact of physician preferences for homeopathic or conventional medicines on patients with musculoskeletal disorders: results from the EPI3-MSD cohort.

OBJECTIVE: The objective of this study was to assess the effect of physician practicing preferences (PPP) in primary care for homeopathy (Ho), CAM (Complementary and alternative medicines) with conventional medicine (Mx) or exclusively conventional medicine (CM) on patients with musculoskeletal disorders (MSDs), with reference to clinical progression, drug consumption, side effects and loss of therapeutic opportunity. METHODS: The EPI3-MSD study was a nationwide observational cohort of a representative sample of general practitioners (GP) and their patients in France. Recruitment of GP was stratified by PPP, which was self-declared. Diagnoses and comorbidities were recorded by GP at inclusion. Patients completed a standardized telephone interview at inclusion, one, three and twelve months, including MSD-functional scales and medication consumption. RESULTS: 1153 MSD patients were included in the three PPP groups. Patients did not differ between groups except for chronicity of MSDs (>12 weeks), which was higher in the Ho group (62.1%) than in the CM (48.6%) and Mx groups (50.3%). The twelve-month development of specific functional scores was identical across the three groups after controlling for baseline score (p > 0.05). After adjusting for propensity scores, NSAID use over 12 months was almost half in the Ho group (OR, 0.54; 95%CI, 0.38-0.78) as compared to the CM group; no difference was found in the Mx group (OR, 0.81; 95% CI: 0.59-1.15). CONCLUSION: MSD patients seen by homeopathic physicians showed a similar clinical progression when less exposed to NSAID in comparison to patients seen in CM practice, with fewer NSAID-related adverse events and no loss of therapeutic opportunity.

Contribution of modeling approaches and virtual populations in transposing the results of clinical trials into real life and in enlightening public health decisions.

Modeling consists in aggregating separate pieces of knowledge, according to a given structure and rules. It allows studying the behavior of more or less complex systems by simulation techniques. Modeling is used in different state-of-the-art technological domains (meteorology, aeronautics). Its use has grown for the evaluation of medicines and medical devices, from conception to prescription (marketing authorization, reimbursement, price setting and re-registrations). It follows a scientific approach and is the object of good practice recommendations. Coupling models to virtual populations allows obtaining realistic results at the population level, testing diagnostic or therapeutic strategies, as well as estimating the consequences of transposing the results of clinical trials to the population. Through examples, the participants of the Round Table analyzed the contributions of the coupling of models and realistic virtual populations, and proposed guidelines for their judicious and systematic use.

Solving the Evidence Interpretability Crisis in Health Technology Assessment: A Role for Mechanistic Models?

Health technology assessment (HTA) aims to be a systematic, transparent, unbiased synthesis of clinical efficacy, safety, and value of medical products (MPs) to help policymakers, payers, clinicians, and industry to make informed decisions. The evidence available for HTA has gaps-impeding timely prediction of the individual long-term effect in real clinical practice. Also, appraisal of an MP needs cross-stakeholder communication and engagement. Both aspects may benefit from extended use of modeling and simulation. Modeling is used in HTA for data-synthesis and health-economic projections. In parallel, regulatory consideration of model informed drug development (MIDD) has brought attention to mechanistic modeling techniques that could in fact be relevant for HTA. The ability to extrapolate and generate personalized predictions renders the mechanistic MIDD approaches suitable to support translation between clinical trial data into real-world evidence. In this perspective, we therefore discuss concrete examples of how mechanistic models could address HTA-related questions. We shed light on different stakeholder's contributions and needs in the appraisal phase and suggest how mechanistic modeling strategies and reporting can contribute to this effort. There are still barriers dissecting the HTA space and the clinical development space with regard to modeling: lack of an adapted model validation framework for decision-making process, inconsistent and unclear support by stakeholders, limited generalizable use cases, and absence of appropriate incentives. To address this challenge, we suggest to intensify the collaboration between competent authorities, drug developers and modelers with the aim to implement mechanistic models central in the evidence generation, synthesis, and appraisal of HTA so that the totality of mechanistic and clinical evidence can be leveraged by all relevant stakeholders.

Benchmarking clinical management of spinal and non-spinal disorders using quality of life: results from the EPI3-LASER survey in primary care.

Concerns have been raised regarding sub-optimal utilization of analgesics and psychotropic drugs in the treatment of patients with chronic musculoskeletal disorders (MSDs) and their associated co-morbidities. The objective of this study was to describe drug prescriptions for the management of spinal and non-spinal MSDs contrasted against a standardized measure of quality of life. A representative population sample of 1,756 MSDs patients [38.5% with spinal disorder (SD) and 61.5% with non-spinal MSDs (NS-MSD)] was drawn from the EPI3-LASER survey of 825 general practitioners (GPs) in France. Physicians recorded their diagnoses and prescriptions on that day. Patients provided information on socio-demographics, lifestyle and quality of life using the Short Form 12 (SF-12) questionnaire. Chronicity of MSDs was defined as more than 12 weeks duration of the current episode. Chronic SD and NS-MSD patients were prescribed less analgesics and non-steroidal anti-inflammatory drugs than their non-chronic counterpart [odds ratios (OR) and 95% confidence intervals (CI), respectively: 0.4, 0.2-0.7 and 0.5, 0.3-0.6]. They also had more anxio-depressive co-morbidities reported by their physicians (SD: 16.1 vs.7.4%; NS-MSD: 21.6 vs. 9.5%) who prescribed more antidepressants and anxiolytics with a difference that was statistically significant only for spinal disorder patients (OR, 95% CI: 2.0, 1.1-3.6). Psychotropic drugs were more often prescribed in patients in the lower quartile of SF-12 mental score and prescriptions of analgesics in the lower quartile of SF-12 physical score (P < 0.001). In conclusion, anxiety and depressive disorders were commonly reported by GPs among chronic MSD patients. Their prescriptions of psychotropic and analgesic drugs were consistent with patients' self-rated mental and physical health.

Who seeks primary care for musculoskeletal disorders (MSDs) with physicians prescribing homeopathic and other complementary medicine? Results from the EPI3-LASER survey in France.

BACKGROUND: There is a paucity of information describing patients with musculoskeletal disorders (MSDs) using complementary and alternative medicines (CAMs) and almost none distinguishing homeopathy from other CAMs. The objective of this study was to describe and compare patients with MSDs who consulted primary care physicians, either certified homeopaths (Ho) or regular prescribers of CAMs in a mixed practice (Mx), to those consulting physicians who strictly practice conventional medicine (CM), with regard to the severity of their MSD expressed as chronicity, co-morbidity and quality of life (QOL). METHODS: The EPI3-LASER study was a nationwide observational survey of a representative sample of general practitioners and their patients in France. The sampling strategy ensured a sufficient number of GPs in each of the three groups to allow comparison of their patients. Patients completed a questionnaire on socio-demographics, lifestyle and QOL using the Short Form 12 (SF-12) questionnaire. Chronicity of MSDs was defined as more than twelve weeks duration of the current episode. Diagnoses and co-morbidities were recorded by the physician. RESULTS: A total of 825 GPs included 1,692 MSD patients (predominantly back pain and osteoarthritis) were included, 21.6% in the CM group, 32.4% Ho and 45.9% Mx. Patients in the Ho group had more often a chronic MSD (62.1%) than the CM (48.6%) or Mx (50.3%) groups, a result that was statistically significant after controlling for patients' characteristics (Odds ratio = 1.43; 95% confidence interval (CI): 1.07 - 1.89). Patients seen by homeopaths or mixed practice physicians who were not the regular treating physician, had more often a chronic MSD than those seen in conventional medicine (Odds ratios were 1.75; 95% CI: 1.22 - 2.50 and 1.48; 95% CI: 1.06 - 2.12, respectively). Otherwise patients in the three groups did not differ for co-morbidities and QOL. CONCLUSION: MSD patients consulting primary care physicians who prescribed homeopathy and CAMs differed from those seen in conventional medicine. Chronic MSD patients represented a greater proportion of the clientele in physicians offering alternatives to conventional medicine. In addition, these physicians treated chronic patients as consulting rather than regular treating physicians, with potentially important impacts upon professional health care practices and organisation.

Impact of drugs on the environment: state of play, risks, evaluation, communication.

The aim of this Round Table was to perform an initial assessment of the state of play of the impact of drugs on the environment. Demographic growth throughout the world and drug consumption which is constantly on the increase result in an ever increasing presence of medicinal substances in the various compartments (air, water, soil) with potential repercussions on the environment and on health. For the first time, the Giens pharmacology workshop have scheduled this topic outside the conventional sphere of action of Giens. A very high level of interest in this topic came forward both from the members of the round table and the listeners and it is certain that the round table opens the door to new initiatives for a subject about which there is still little knowledge. The following issues were therefore successively addressed: the fragmentation of the knowledge about the subject and its deficiencies concerning the impact on health, both of the wastes as a whole and that of specific drugs, the performances of the water treatment methods, the sources of pollution, the environmental impact, the lines of regulatory development, the impact on the environment and health and the training programmes to be set up among all protagonists, both professional and in the general public.

Epidemiology, Mortality and Healthcare Resource Utilization Associated With Systemic Sclerosis-Associated Interstitial Lung Disease in France.

Objectives: To investigate the clinical characteristics, epidemiology, survival estimates and healthcare resource utilization and associated costs in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) in France. Methods: The French national administrative healthcare database, the Système National des Données de Santé (SNDS), includes data on 98.8% of the French population, including data relating to ambulatory care, hospitalizations and death. In our study, claims data from the SNDS were used to identify adult patients with SSc-ILD between 2010 and 2017. We collected data on clinical features, incidence, prevalence, survival estimates, healthcare resource use and costs. Results: In total, 3,333 patients with SSc-ILD were identified, 76% of whom were female. Patients had a mean age [standard deviation (SD)] of 60.6 (14.4) years and a mean (SD) individual study duration of 3.9 (2.7) years. In 2016, the estimated overall incidence and prevalence were 0.69/100,000 individuals and 5.70/100,000 individuals, respectively. The overall survival estimates of patients using Kaplan-Meier estimation were 93, 82, and 55% at 1, 3, and 8 years, respectively. During the study, 98.7% of patients had ≥1 hospitalization and 22.3% of patients were hospitalized in an intensive care unit. The total annual mean healthcare cost per patient with SSc-ILD was €25,753, of which €21,539 was related to hospitalizations. Conclusions: This large, real-world longitudinal study provides important insights into the epidemiology of SSc-ILD in France and shows that the disease is associated with high mortality, healthcare resource utilization and costs. SSc-ILD represents a high burden on both patients and healthcare services. Clinical Trial Registration:www.ClinicalTrials.gov, identifier: NCT03858842.
