RESUMO

INTRODUCTION: Because patients and patient organizations want to strengthen their role in the care pathway and drug evaluation and in order to improve pharmacovigilance activities, European competent authorities implemented regulations to allow direct reporting of adverse drug reactions related to medicinal products by patients in 2012. OBJECTIVES: To describe evolution and analyze determinants of patient reporting activity in France in order to assess patient involvement in pharmacovigilance. METHOD: Using the French national pharmacovigilance database, univariate and multivariate analyses were performed to compare the characteristics of adverse drug reaction (ADR) reports from patients and healthcare professionals (HCP) between 2011 and 2020. The relationship between regional patient ADR report activity and regional care provision and socio-professional characteristics was analyzed using the principal component analysis. RESULTS: A significant and higher increase in ADR reports over time from patients (r = 0.89, p < 0.001) compared to HCP (r = 0.27, p = 0.002) has been observed. Patient ADR report activities compared to HCP concerned more women (80% vs. 55%, p < 0.001), younger age classes (p < 0.001), reporting through web portal (83% vs. 17%, p < 0.001), and less serious events (26% vs. 63%, p < 0.001). In the principal component analysis, regional patient reporting activity was related to socio-professional categories, age classes, and densities of hospital beds and physicians. CONCLUSION: Our results confirm an increasing involvement of patients in ADR report activities. The determinants of patient reporting activities are not only related to drug and medical factors but also to social factors. Digital tools may also play a role in health democracy in pharmacovigilance.

RESUMO

PURPOSE: Most schizophrenic patients have mild to moderate cognitive impairment in the early stages of schizophrenia. The aim was to compare the long-term effects of various antipsychotic drugs on overall cognition and on specific cognitive domains in patients with schizophrenia or related disorders. METHODS: We searched MEDLINE and EMBASE for randomized controlled trials in which oral formulations of second-generation antipsychotic drugs were compared head-to-head or against placebo or against haloperidol. Trials had to be of at least 6 months duration to be included. We used a network meta-analysis to combine direct and indirect comparisons of the cognitive effects between antipsychotics. RESULTS: Nine studies were eligible. The median trial duration was 52 weeks. Quetiapine, olanzapine and risperidone had better effects on global cognitive score than amisulpride (p < 0.05) and haloperidol (p < 0.05). When memory tasks were considered, ziprasidone had better effect than amisulpride (0.28 [0.02-0.54]) and haloperidol (0.32 [0.09-0.55]). Quetiapine was better than other drugs (p < 0.001) on attention and processing speed tasks, followed by ziprasidone (p < 0.05) and olanzapine (p < 0.05). The effects of quetiapine, risperidone and olanzapine were better than those of amisulpride (p < 0.05) on executive functions. CONCLUSIONS: Our results suggest differences between antipsychotics in their effect on the overall cognitive score in schizophrenia. Quetiapine and olanzapine had the most positive effects, followed by risperidone, ziprasidone, amisulpride and haloperidol in that order. Significant differences were also observed according to specific cognitive tasks.

RESUMO

BACKGROUND: It remains unknown if physical inactivity and excess adiposity increases 24-h central blood pressure and arterial stiffness in young adults. This study examined 24-h central blood pressure and indirect measures of arterial stiffness (e.g., central pulse pressure) in physically inactive young adults with and without excess adiposity. METHODS: Body fat and ambulatory 24-h blood pressure were measured in 31 young adults (men: 22±4 years, N.=15; women: 22±5 years, N=16). Multi-frequency bioelectrical impedance measured body fat. Normal adiposity was defined as <20% body fat in men and <32% body fat in women, whereas excess adiposity was defined as ≥20% and ≥32% in men and women, respectively. Ambulatory 24-h central blood pressure was calculated based on brachial blood pressure and volumetric displacement waveforms. RESULTS: By design, the normal adiposity group had a lower body fat percentage (men: 15.5±4.6%; women: 20.8±2.5%) compared to the physically inactive excess adiposity group (men: 29.8±5.4%; women: 34.3±7.5%). Men and women with excess adiposity group had elevated central blood pressure (central systolic, P<0.05 vs. normal adiposity groups). Central pulse pressure was elevated in the excess adiposity group (men: 45±5 mmHg; women: 41±9 mmHg) compared to normal adiposity groups (men: 36±4 mmHg; women: 32±3 mmHg, P<0.05 for both), while other arterial stiffness (augmentation index and ambulatory arterial stiffness index) measures trended toward significance only in men with excess adiposity. CONCLUSIONS: Physically inactive men and women with excess adiposity have increased 24h central blood pressure and pulse pressure compared to physically inactive young adults with normal adiposity.

RESUMO

INTRODUCTION: Having a mental illness has been and remains even now, a strong barrier to effective medical care. Most mental illness, such as schizophrenia, bipolar disorder, and depression are associated with undue medical morbidity and mortality. It represents a major health problem, with a 15 to 30 year shorter lifetime compared with the general population. METHODS: Based these facts, a workshop was convened by a panel of specialists: psychiatrists, endocrinologists, cardiologists, internists, and pharmacologists from some French hospitals to review the information relating to the comorbidity and mortality among the patients with severe mental illness, the risks with antipsychotic treatment for the development of metabolic disorders and finally cardiovascular disease. The French experts strongly agreed on these points: that the patients with severe mental illness have a higher rate of preventable risk factors such as smoking, addiction, poor diet, lack of exercise; the recognition and management of morbidity are made more difficult by barriers related to patients, the illness, the attitudes of medical practitioners, and the structure of healthcare delivery services; and improved detection and treatment of comorbidity medical illness in people with severe mental illness will have significant benefits for their psychosocial functioning and overall quality of life. GUIDELINES FOR INITIATING ANTIPSYCHOTIC THERAPY: Based on these elements, the French experts propose guidelines for practising psychiatrists when initiating and maintaining therapy with antipsychotic compounds. The aim of the guidelines is practical and concerns the detection of medical illness at the first episode of mental illness, management of comorbidity with other specialists, family practitioner and follow-up with some key points. The guidelines are divided into two major parts. The first part provides: a review of mortality and comorbidity of patients with severe mental illness: the increased morbidity and mortality are primarily due to premature cardiovascular disease (myocardial infarction, stroke...).The cardiovascular events are strongly linked to non modifiable risk factors such as age, gender, personal and/or family history, but also to crucial modifiable risk factors, such as overweight and obesity, dyslipidemia, diabetes, hypertension and smoking. Although these classical risk factors exist in the general population, epidemiological studies suggest that patients with severe mental illness have an increased prevalence of these risk factors. The causes of increased metabolic and cardiovascular risk in this population are strongly related to poverty and limited access to medical care, but also to the use of psychotropic medication. A review of major published consensus guidelines for metabolic monitoring of patients treated with antipsychotic medication that have recommended stringent monitoring of metabolic status and cardiovascular risk factors in psychiatric patients receiving antipsychotic drugs. There have been six attempts, all published between 2004 and 2005: Mount Sinai, Australia, ADA-APA, Belgium, United Kingdom, Canada. Each guideline had specific, somewhat discordant, recommendations about which patients and drugs should be monitored. However, there was agreement on the importance of baseline monitoring and follow-up for the first three to four months of treatment, with subsequent ongoing reevaluation. There was agreement on the utility of the following tests and measures: weight and height, waist circumference, blood pressure, fasting plasma glucose, fasting lipid profile. In the second part, the French experts propose guidelines for practising psychiatrists when initiating and maintaining therapy with antipsychotic drugs: the first goal is identification of risk factors for development of metabolic and cardiovascular disorders: non modifiable risk factors: these include: increasing age, gender (increased rates of obesity, diabetes and metabolic syndrome are observed in female patients treated with antipsychotic drugs), personal and family history of obesity, diabetes, heart disease, ethnicity as we know that there are increased rates of diabetes, metabolic syndrome and coronary heart disease in patients of non European ethnicity, especially among South Asian, Hispanic, and Native American people. Modifiable risk factors: these include: obesity, visceral obesity, smoking, physical inactivity, and bad diet habits. Then the expert's panel focussed on all the components of the initial visit such as: family and medical history; baseline weight and BMI should be measured for all patients. Body mass index can be calculated by dividing weight (in kilograms) by height (in meters) squared; visceral obesity measured by waist circumference; blood pressure; fasting plasma glucose; fasting lipid profiles. These are the basic measures and laboratory examinations to do when initiating an antipsychotic treatment. ECG: several of the antipsychotic medications, typical and atypical, have been shown to prolong the QTc interval on the ECG. Prolongation of the QTc interval is of potential concern since the patient may be at risk for wave burst arrhythmia, a potentially serious ventricular arrhythmia. A QTc interval greater than 500 ms places the patient at a significantly increased risk for serious arrhythmia. QTc prolongation has been reported with varying incidence and degrees of severity. The atypical antipsychotics can also cause other cardiovascular adverse effects with, for example, orthostatic hypotension. Risk factors for cardiovascular adverse effects with antipsychotics include: known cardiovascular disease, electrolyte disorders, such as hypokaliemia, hypomagnesaemia, genetic characteristics, increasing age, female gender, autonomic dysfunction, high doses of antipsychotics, the use of interacting drugs, and psychiatric illness itself. In any patient with pre-existing cardiac disease, a pre-treatment ECG with routine follow-up is recommended. CONCLUDING REMARKS: Patients on antipsychotic drugs should undergo regular testing of blood sugar, lipid profile, as well as body weight, waist circumference and blood pressure, with recommended time intervals between measures. Clinicians should track the effects of treatment on physical and biological parameters, and should facilitate access to appropriate medical care. In order to prevent or limit possible side effects, information must be given to the patient and his family on the cardiovascular and metabolic risks. The cost-effectiveness of implementing these recommendations is considerable: the costs of laboratory tests and additional equipment costs (such as scales, tape measures, and blood pressure devices) are modest. The issue of responsibility for monitoring for metabolic abnormalities is much debated. However, with the prescription of antipsychotic drugs comes the responsibility for monitoring potential drug-induced metabolic abnormalities. The onset of metabolic disorders will imply specific treatments. A coordinated action of psychiatrists, general practitioners, endocrinologists, cardiologists, nurses, dieticians, and of the family is certainly a key determinant to ensure the optimal care of these patients.

RESUMO

BACKGROUND AND OBJECTIVES: Because patients who are to undergo surgery must give their consent to planned postoperative care, clear and complete information on postoperative pain management should be given. The aim of this quality-of-care study was to evaluate by inquiry the impact of written information describing postoperative pain management on the quality and type of information retained, and patient participation in discussing and agreeing to the postoperative pain management programme during the presurgical anaesthesiology consultation. METHODS: Prospective before and after interventional surveys, each lasting 3 weeks and conducted at a 6-month interval (time required to prepare the written information), used a standardized anonymous questionnaire given to patients after the anaesthesiology consultation. Questions requiring a 'yes' or 'no' response assessed the quality of information and what information was retained by the patient, the extent of the patient's interaction during the discussion with the anaesthesiologist and his/her agreement with the postoperative pain management programme. RESULTS: Among the 180 before-group patients included, 16.7% reported receiving verbal information during the anaesthesiology consultation, none retained all seven principal side-effects of morphine, 14.4% considered the information to be thorough, 20.6% understood it, 16.7% claimed that it had helped them participate in the discussion and 14.4% concurred with the postoperative pain management programme. Compared to the before inquiry, significantly higher percentages of the 107 after-group patients (given written information before the anaesthesiology consultation) responded as having received verbal information during the anaesthesiology consultation (57.0%), retained morphine's main side-effects (12.1%), deemed the information thorough (58.9%) and understandable (53.3%), had participated in the discussion (47.7%) and agreed with the postoperative pain management programme (51.4%). CONCLUSION: Written information on postoperative pain management distributed before the presurgical anaesthesiology consultation improved the quality of information retained, facilitated discussion with the anaesthesiologist and patient agreement with the postoperative pain management programme.

RESUMO

Whether nicotine has therapeutic effects on Parkinson's disease (PD) symptoms is controversial, but high doses and chronic treatment have never been tested. We report the results of a pilot, open-label trial to assess the safety and possible efficacy of chronic high doses of nicotine. Six patients with advanced idiopathic PD received increasing daily doses of transdermal nicotine up to 105 mg/day over 17 weeks. All patients but one accepted the target dose. Nausea and vomiting were frequent but moderate, and occurred in most of the patients (four of six) who received over 90 mg/day and 14 weeks of nicotine treatment. During the plateau phase, patients improved their motor scores and dopaminergic treatment was reduced. These results confirm the feasibility of chronic high dose nicotinic treatment in PD but warrant validation of the beneficial effects by a randomized controlled trial.

RESUMO

OBJECTIVE: The metabolic syndrome is a loosely defined cluster of cardiovascular risk factors including low HDL cholesterol, hypertriglyceridemia, glucose intolerance, and hypertension. Evidence for inclusion of these features in the syndrome has mostly come from cross-sectional studies, and a few studies have examined how the various factors change together over time. RESEARCH DESIGN AND METHODS: We conducted a prospective population-based cohort study of 937 individuals aged 40-65 years who underwent oral glucose tolerance testing on two occasions at 4.5-year intervals. Changes in the components of the metabolic syndrome were analyzed by principal component analysis in the entire population and in a subgroup of 471 individuals who did not receive pharmaceutical therapy for hypertension and dyslipidemia. RESULTS: Principal component analysis identified three independent factors in men: a blood pressure factor (systolic and diastolic blood pressure and BMI), a glucose factor (fasting and 120-min postload glucose, BMI, waist-to-hip ratio [WHR], and fasting insulin level), and a lipid factor (triglycerides and HDL cholesterol, BMI, WHR, and fasting insulin level). In women, an additional factor was identified, which included BMI, WHR, fasting insulin, and triglycerides. Analysis of the contribution of these variables to the different subdimensions indicated that BMI was the central feature of the syndrome in both sexes. CONCLUSIONS: This analysis of change in the features of the metabolic syndrome over time provides evidence of the fundamental importance of obesity in the origin of this disorder.

RESUMO

OBJECTIVE: To assess the natural progression of cognitive impairment in Huntington's disease (HD) and to reveal factors that may mask this progression. BACKGROUND: Although numerous cross-sectional studies reported cognitive deterioration at different stages of the disease, progressive cognitive deterioration has been, up to now, difficult to demonstrate in neuropsychological longitudinal studies. METHODS: The authors assessed 22 patients in early stages of HD at yearly intervals for 2 to 4 years (average, 31.2 +/- 10 months), using a comprehensive neuropsychological battery based on the Core Assessment Program for Intracerebral Transplantation in Huntington's Disease (CAPIT-HD). RESULTS: The authors observed a significant decline in different cognitive functions over time: these involved primarily attention and executive functions but also involved language comprehension, and visuospatial immediate memory. Episodic memory impairment that was already present at the time of enrollment did not show significant decline. The authors found a significant retest effect at the second assessment in many tasks. CONCLUSION: Many attention and executive tasks adequately assess the progression of the disease at an early stage. For other functions, the overlapping of retest effects and disease progression may confuse the results. High interindividual and intraindividual variability seem to be hallmarks of the disease.

RESUMO

Insulin and non-esterified fatty acids (NEFA) are important regulators of triglyceride metabolism. The relations between these compounds and the effect of a common 3 amino acid deletion in the apolipoprotein B (ApoB) signal peptide (SP) following an oral glucose challenge have been investigated. The frequency of the shorter SP-24 allele was 32% (95% C.I. 29.5-36.5) in 725 subjects undergoing an oral glucose tolerance test (OGTT). Fasting plasma triglyceride concentration was positively correlated with fasting plasma insulin concentration and negatively with the degree of plasma NEFA suppression following the glucose challenge. Linear regression analysis showed the relation between triglyceride concentration and NEFA suppression, but not the relation between triglyceride concentration and fasting insulin, to be altered by the SP polymorphism in men but not in women. The strength of the association was dependent on the number of SP-24 alleles, with SP-24 homozygotes showing the greatest dependence (men P=0.031, women P=0. 914). It was proposed that the complex regulation of very low density lipoprotein (VLDL) output by NEFA and by insulin may explain, at least in part, the conflicting reports concerning the presence of the ApoB SP polymorphism, fasting serum lipids and ischaemic heart disease (IHD).

RESUMO

Infiltration of activated lymphocytes and monocytes is a key phenomenon in the pathogenesis of Guillain-Barré syndrome (GBS) and experimental autoimmune neuritis (EAN). To investigate the role of chemokines, we determined the blood and nerve tissue expression of monocyte chemoattractant protein 1 (MCP-1), a major chemoattractant of monocytes and activated lymphocytes, and its receptor CCR2 in GBS and EAN. MCP-1 circulating levels (ng/ml) in GBS were increased at the time of progression, peaked at the time of plateau and normalized with recovery. MCP-1 circulating levels were the highest in the most disabled patients. The number of circulating CCR2 positive cells was lower in patients with GBS than in healthy subjects (p<0.004). In GBS, MCP-1 expression was observed in epineurial and endoneurial vessels, on infiltrating cells, Schwann cells and in the endoneurial extracellular matrix. Some CCR2 positive cells were observed in nerve biopsies of GBS patients. In EAN, a slight positivity for MCP-1 was observed in the sciatic nerve. There was no circulating CCR2 positive cells. However, at the time of plateau, a conspicuous infiltration of CCR2 positive cells was observed in the sciatic nerve that was no longer observed at the time of recovery. These results suggest that MCP-1 and CCR2 may participate to the recruitment of circulating mononuclear cells in nerve tissue in EAN and GBS.

RESUMO

OBJECTIVE: To describe oral antibiotic prescription in the community. DESIGN: Audit of anti-infective prescribing in office-based medical practice. SETTING: Center of France, in the Loiret, a 600,000 inhabitant administrative division. MAIN OUTCOME MEASURES: Clinical hypothesis and antimicrobial drugs used as well as daily doses and durations of treatment. RESULTS: Respiratory tract infections with a presumed viral etiology accounted for 36% of prescriptions. In children, a high percentage of antibiotic prescriptions were underdosed as compared to clinical recommendations, particularly in acute otitis media. The variability of the daily dose was high, with coefficients of variation over 40% in acute otitis media or acute tracheobronchitis. Whatever the clinical hypothesis, the duration of treatment was close to 8 days. In acute otitis media, the coefficient of variation was 14%, the lowest for all diagnoses. CONCLUSION: Our investigation identified two main areas for improving antimicrobial drug prescribing: (1) reduction of useless prescriptions in respiratory tract infections with a presumed viral etiology, and (2) increasing the prescribed daily dose of antimicrobials to the recommended levels.

RESUMO

In previous studies, a cross-sectional association has been described between blood pressure (BP) and nonesterified fatty acid (NEFA) concentrations. The direction of causality, and thus, the mechanism explaining this relationship, remains uncertain. Therefore, we analyzed a prospective population-based cohort of 937 subjects who underwent an oral glucose tolerance test (OGTT) on two occasions separated by 4.5 years. In cross-sectional analysis, NEFA measures were correlated with systolic and diastolic BP, both at baseline and at follow-up study. In longitudinal analysis, baseline systolic and diastolic BP predicted changes in fasting NEFA levels (both P < .01). However, baseline NEFA levels did not predict change in BR In multivariate analysis, the relationship between baseline BP and change in fasting NEFA was independent of age and sex. Obesity and its interaction with BP did not explain this association. Absolute changes in NEFA concentrations were greater among subjects who were hypertensive at baseline compared with the normotensive individuals. This change was greater in subjects treated with diuretics compared with those treated with beta-adrenergic antagonists (P < .01), an observation that provides support for a role of sympathetic nervous system (SNS) activity in explaining the relationship between BP and NEFA concentration.

RESUMO

OBJECTIVE: To compare antihypertensive drug use between diabetics and non-diabetics and to analyse the change between the two last decennial national surveys on health and medical care in France, in 1981 and 1992. MATERIAL AND METHODS: These surveys included respectively 12,725 and 13,887 adults over 25 years. Use of all antihypertensive drugs marketed in France was compared between orally treated diabetics and non-diabetics who were non-insulin and non-oral anti-diabetic treated population. RESULTS: In 1981, while diuretics were the first treatment in both populations (53% in diabetics vs 60% in non-diabetics, non significant), central inhibitors (31 vs 16% respectively, p<0.001) were the second agent among diabetic patients instead of beta blockers in non-diabetic patients (13 vs 22% respectively, p<0.05). In 1992, beta blockers were also less used in diabetics (21 versus 33%, p=0.001). In contrast, ACE inhibitors were more used (43 versus 35%, p=0.06). In both surveys and populations, other classes (reserpin, vasodilator and alpha blockers) had minor place in the strategy. The frequency of combinations of antihypertensive drugs was similar in both surveys and populations. The preferred combination treatment was in both populations reserpin with diuretics in 1981 (7 vs 9%, non significant) and ACE inhibitors with diuretics in 1992 (18 vs 18%). CONCLUSION: Independently of guidelines, our data suggest that the strategy of hypertension treatment has changed last years and that prescriptions were more targeted for diabetic patients.

RESUMO

PURPOSE: To look at how well residency directors in family medicine predict the performances of their candidates on the Quebec Licensing Examination (QLEx) for family physicians. METHOD: The four family medicine program directors in Quebec were asked in the spring of 1992 to identify the ten residents from their own programs who would get the highest marks on the QLEx and the ten who would get the lowest marks. From the results of these candidates, and those of the intermediate groups defined by default, the prediction abilities of the program directors were assessed. RESULTS: Descriptive statistics showed that the program directors had difficulties discriminating among the different groups and tended to collapse the predicted scores toward the total mean. Analysis-of-variance studies confirmed the absence of difference between the predicted weak and intermediate groups as well as between the predicted intermediate and strong groups for each program and for each QLEx component. Regression analysis as well as eta 2 studies showed that the program directors' prediction abilities were low for all components and represented less than 25% of the explained variance of the QLEx scores. CONCLUSION: The residency directors did not accurately categorize their residents' performances on the QLEx. Both the evaluations of program directors and terminal examination results are complementary approaches to clinical competence assessment and should be used for licensure.

RESUMO

BACKGROUND: A new licensing examination for family physicians was introduced in the Province of Quebec, Canada, in 1990. It contains a newly developed, standardized, patient-based objective structured clinical examination (OSCE) used in complementarity with two other instruments (Short Answers Management Problems [SAMPs] and Simulated Office Orals [SOOs]) that have been used for many years by the College of Family Physicians of Canada (CFPC) for certification purposes. This research studied the criterion validity of the OSCE using the last instruments as criteria. METHODS: The results of the 172 spring 1994 candidates were analyzed. Cronbach alpha reliability coefficients were computed. Pearson's correlation coefficients and regression analysis measured the extent to which scores on the new Quebec OSCE correlated with the scores on the CFPC instruments. RESULTS: Correlation coefficients were significant between the Quebec OSCE scores and the CFPC examination total scores (.700), the SAMPs scores (.634), and the SOOs scores (.514). Multiple regression analysis confirmed that scores on the Quebec OSCE explained a significant but still limited proportion of the variation in scores of the CFPC examination. DISCUSSION: This study supports the criterion validity of the Quebec OSCE used in the licensing examination. However, differences in the skills assessed by each instrument and in the clinical situations presented exist between the Quebec instrument and the two national instruments. These differences, plus the variation in the scores obtained by the candidates on the three instruments, support the decision of the Quebec licensing organization to use them in complementarity.

RESUMO

OBJECTIVES: To summarize the methods encountered in a gynecological department for teaching medical students. STUDY: Review of the Medline literature underlying the benefits and disadvantages of each method using the issues of the modern theories of teaching. RESULTS: All the methods are helpful for learning, with different and complementary objectives. Students can constitute a set of skills using a teaching program containing clear objectives and evaluation on which the future medical practice will be based. CONCLUSION: Students have immediate benefits from an active clinical learning involving them and are prepared to the Continued Medical Education.

RESUMO

A new scientific discipline: Progress in scientific knowledge, advances in therapeutic innovation, the development of new drugs and the continuing need for optimal drug use impose a new approach to the rational assessment of public health needs and the risks and benefits of therapeutic intervention. In the near future, a new scientific discipline, pharmaceutical epidemiology, will play a leading role. France seems to be a bit behind other western countries in this area. Goal setting: The objectives of industrial firms do not necessarily cover all aspects of the overall goals of society. If the scientific community leaves the development and implementation of pharmaceutical epidemiology in the hands of industrial firms alone, they risk seeing its field of action limited to industrial objectives. The goals of this new discipline must be defined within an unbiased framework aimed at meeting the needs of society in general. Organization: The development of pharmaceutical epidemiology as an integral part of medical research requires a clear definition of its objectives, methods, working hypotheses and time and human allocations. In this context, pharmaceutical epidemiology should be organized within the University and scientific settings currently contributing to scientific research in France (INSERM, CNRS, ORSTOM, etc.). Creating favorable conditions: A pharmaceutical epidemiology network with adequate human and material resources is needed. The wide range of needs expressed by existing institutions (Drug Agency, Prescription and Drug Use Observatory, industrial firms, the national health insurance system, physician and pharmacist associations) pleads for a nationally organized project working in the public domain.

RESUMO

There is no Faculty of Medicine in the New Brunswick province of Canada. Thirty-three percent of its population is francophone. In an effort to improve the health status of this population, which is known to be inferior to that of its anglophone counterpart, and to fill the gap in terms of the lack of francophone physicians, a partnership was developed with the University of Sherbrooke's medical school. Therefore, a francophone medical training programme was established in New Brunswick, and as a community-based programme, it is oriented to serve the specific needs of this target group. This integrated and collaborative approach between the principal health partners has had a positive impact on improving the health status of the francophone population and on the francophone medical resources. It is a solid demonstration of the Towards Unity for Health approach and of the social responsibility of a medical school.
