Use of analgesics in France, following dextropropoxyphene withdrawal.

BACKGROUND: In 2009, the European Medicines Agency recommended withdrawal of dextropropoxyphene (DXP); in March 2011 it was withdrawn from the market in France. Up until that time the combination dextropropoxyphene-paracetamol (DXP/PC) was widely used for analgesia. At withdrawal, French regulators recommended that DXP/PC be replaced by other step 2 analgesics, i.e. tramadol, codeine, or opium-containing drugs, or by PC for a weak level of pain. To investigate prescribing behaviours after DXP/PC withdrawal, dispensations of analgesics before and after withdrawal were analysed. METHODS: Aggregated dispensation data of analgesics prescribed between January 2009 and December 2012 in the Rhône-Alpes region were obtained from the general health insurance claims data; changes in analgesic dispensation over time were analysed with the ATC/DDD methodology. Pre (Jan-June 2009) and post-withdrawal (Jan-June 2012) changes of DDDs where computed for each analgesic step. RESULTS: The dispensations of DXP/PC experienced a two-step decrease until 2011. Over the withdrawal period 2009-2012, there was a 14% decrease in the overall use of analgesic (from 109 to 94 DDDs), while the use of step 2 analgesics declined by 46% (- 22 DDDs, from 47 to 25 DDDs). This latter decline included a cessation of use of DXP/PC (29 DDDs in 2009) that were only in part (+ 7 DDDs, from 18 to 25 DDDs) compensated by increased use of codeine, tramadol and opium, in monotherapy or combined with PC. For step 1 analgesics, use increased with 9%, mostly PC (+ 8 DDDs, from 31 to 39 DDDs). Step 3 analgesics dispensations remained largely unchanged over this period (around 3 DDDs). CONCLUSIONS: In the Rhône-Alpes region, DXP/PC withdrawal was accompanied in part by an increased use of same level analgesics, and in part by an increased use of PC in monotherapy. The extent of DXP/PC use before withdrawal, and the increased use of PC after DXP withdrawal, underline the complexity of pain management.

Anti-osteoporotic treatments in France: initiation, persistence and switches over 6 years of follow-up.

Limited information is available on anti-osteoporotic treatment initiation patterns in France. In 2006-2013, the most frequently prescribed first-line treatment class for osteoporosis was represented by bisphosphonates (alendronic acid and risedronic acid), followed by strontium ranelate. Persistence with anti-osteoporotic treatment was low, with high proportions of treatment discontinuations and switches. INTRODUCTION: This epidemiological, longitudinal study described first-line treatment initiation, persistence, switches to second-line treatment, and medical care consumption in osteoporotic patients in France during the 2007-2013 period. METHODS: Patients aged ≥50 years, who were recorded in a French claims database and did not die during the observation period, were included if they met ≥1 inclusion criteria for osteoporosis in 2007 (≥1 reimbursement for anti-osteoporotic treatment, hospitalisation for osteoporotic fracture (spine, hip, femur, forearm bones, humerus, wrist), or ≥1 reimbursement for long-term osteoporosis-associated status). We collected data on consumption of anti-osteoporotic treatment (alendronic acid, ibandronic acid, risedronic acid, zoledronic acid, raloxifene, strontium ranelate, teriparatide) and of osteoporosis-related medical care after the date of first reimbursement for anti-osteoporotic treatment. RESULTS: We obtained 2219 patients with a 6-year follow-up and 1387 who initiated an anti-osteoporotic treatment in 2007 and who can be selected for the treatment regimen analysis. The most frequently used first-line treatments were alendronic acid (32.7 %), risedronic acid (22.4 %), strontium ranelate (19.3 %), ibandronic acid (13.1 %) and raloxifene (12.2 %). Among patients who received these treatments, the highest persistence after 6 years was observed for raloxifene (37.3 %), alendronic acid (35.1 %) and risedronic acid (32.3 %). Treatment discontinuations were reported for 35.5 % (raloxifene) to 53.4 % (strontium ranelate) and treatment switches for 27.4 % (alendronic acid) to 56.6 % (ibandronic acid) of these patients. CONCLUSIONS: This study showed that persistence with anti-osteoporotic treatment was relatively low in France, with high proportions of treatment discontinuations and switches, and that patients with osteoporosis were insufficiently monitored by bone specialists.

Costs of perennial allergic rhinitis and allergic asthma increase with severity and poor disease control.

BACKGROUND: Perennial allergic rhinitis (PAR) represents a global and public health problem, due to its prevalence, morbidity, and impact on the quality of life. PAR is frequently associated with allergic asthma (AA). Costs of PAR with or without AA are poorly documented. OBJECTIVE: Our study aimed to detail medical resource utilization (MRU) and related direct cost for PAR, with or without concomitant AA, in France. METHODS: Using Electronic Health Records (EHRs), we identified in 2010 two cohorts of PAR patients, based on General Practitioners' diagnoses and prescribing data, with and without concomitant AA. For each patient, the EHRs were linked to corresponding claims data with MRU and costs during years 2011 to 2013. Predefined subgroup analyses were performed according to severity of PAR and level of AA control. RESULTS: The median annual cost reimbursed by social security system for a patient with PAR, and no AA was 159€ in 2013. This varied from 111€ to 188€ depending on PAR severity. For patients with PAR and concomitant AA, the median annual cost varied between 266€ and 375€, and drug treatment accounted for 42-55% of the costs, depending on asthma control. CONCLUSION: This study linking diagnoses from EHRs to claims data collected valid information on PAR management, with or without concomitant AA, and on related costs. There was a clear increase in costs with severity of PAR and control of AA.

Cardiovascular risk and lifestyle habits of consumers of a phytosterol-enriched yogurt in a real-life setting.

BACKGROUND: Data on the characteristics of consumers of phytosterol-enriched products and modalities of consumption are rare. An observational study evaluating the lifestyle characteristics and cardiovascular risk (CVR) profile of phytosterol-enriched yogurt consumers was performed in France. METHODS: Subjects were recruited from general practitioners via electronic medical records. Data were obtained from 358 consumers and 422 nonconsumers with 519 subject questionnaires (243 consumers, 276 nonconsumers; 67% response). RESULTS: Consumers had more cardiovascular risk factors than nonconsumers (2.0 ± 1.5 versus 1.6 ± 1.4; P < 0.001) and a higher 10-year SCORE cardiovascular risk (1.8 ± 2.0% versus 1.6 ± 2.2%; P = 0.008); they were older (P = 0.030) and had a higher incidence of hypercholesterolaemia (P < 0.001) and family or personal history of heart disease (P = 0.023/P = 0.026, respectively). Among consumers not on cholesterol-lowering medication, 99% were eligible for lifestyle interventions and 56% were eligible for lipid-lowering drug according to European guidelines. Consumers had a healthier lifestyle, with a higher (fruit/vegetable - saturated fatty acid) score than nonconsumers (P = 0.035), focused more on low-intensity leisure activity (P = 0.023), spent more time travelling by foot or bicycle (P = 0.012) and were more likely to act to reduce CVR. Phytosterol-enriched yogurt intake conformed to recommendations in two-thirds of consumers and was mainly consumed because of concerns over cholesterol levels and CVR. CONCLUSIONS: The higher cardiovascular disease risk profile of phytosterol-enriched yogurt consumers corresponds to a population for whom European guidelines recommend lifestyle changes to manage cholesterol. The coherence of the data in terms of risk factors, adherence to lifestyle recommendations and the consumption of phytosterol-enriched yogurt conforming to recommendations reflects a health-conscious consumer population.

[Vigilance level for cardiovascular risk factors in schizophrenic patients]. / Niveau de vigilance des psychiatres pour les facteurs de risque cardiovasculaire chez les patients schizophrènes.

INTRODUCTION: Schizophrenic patients have increased cardiovascular risk factors and morbi-mortality as compared with the general population. OBJECTIVE: To assess the level of French psychiatrists vigilance regarding cardiovascular risk factors in schizophrenic patients. METHODS: Prospective, transverse, multicentric observational study implemented in France in 2007 and conducted by psychiatrists with a liberal activity. The included patients had to meet the following selection criteria: patients ≥ 18 years old, fulfilling the DSM-IV-TR criteria for schizophrenia, treated or not treated for their schizophrenia, with an ambulatory follow-up, without schizophreniform, schizoaffective, or other psychotic disorder. The psychiatrists "vigilance level" for a given cardiovascular risk factor was defined as a systematic investigation of this cardiovascular risk factor for at least 75% of the schizophrenic patients included in the study by the psychiatrist. RESULTS: A total of 382 psychiatrists included 2242 patients, the data collected for 2222 patients were finally analysed. The mean age was 41 years old, 59% were men. The mean BMI was 27 kg/m(2), 34% of the patients were overweight, 23% were obese. The paranoid and residual schizophrenia were the most frequently described subtypes of the disease (41.3 and 25.0% respectively), 58% of the patients were moderately or markedly ill according to the CGI-S scale. Most of the patients were treated with atypical antipsychotics (77%). Only 58% of the psychiatrists were vigilant for the weight of their patients, 38% for the arterial tension, 25% for the family history of premature coronary disease, 14% for the glycemia, 12% for the triglycerides, 10% for HDL cholesterol, 6% for the waist measurement; 35% of the psychiatrists were vigilant for no cardiovascular risk factor. Less than 30% of the psychiatrists recommended their patients to other specialists to manage cardiovascular disorders. CONCLUSION: Similarly to other countries, French psychiatrists provide insufficient care of cardiovascular risk factors of schizophrenic patients in their current clinical practice.

Workshop Report: concepts and methods in the economics of nutrition--gateways to better economic evaluation of nutrition interventions.

Improving health through better nutrition of the population may contribute to enhanced efficiency and sustainability of healthcare systems. A recent expert meeting investigated in detail a number of methodological aspects related to the discipline of nutrition economics. The role of nutrition in health maintenance and in the prevention of non-communicable diseases is now generally recognised. However, the main scope of those seeking to contain healthcare expenditures tends to focus on the management of existing chronic diseases. Identifying additional relevant dimensions to measure and the context of use will become increasingly important in selecting and developing outcome measurements for nutrition interventions. The translation of nutrition-related research data into public health guidance raises the challenging issue of carrying out more pragmatic trials in many areas where these would generate the most useful evidence for health policy decision-making. Nutrition exemplifies all the types of interventions and policy which need evaluating across the health field. There is a need to start actively engaging key stakeholders in order to collect data and to widen health technology assessment approaches for achieving a policy shift from evidence-based medicine to evidence-based decision-making in the field of nutrition.

Nutrition economics - characterising the economic and health impact of nutrition.

There is a new merging of health economics and nutrition disciplines to assess the impact of diet on health and disease prevention and to characterise the health and economic aspects of specific changes in nutritional behaviour and nutrition recommendations. A rationale exists for developing the field of nutrition economics which could offer a better understanding of both nutrition, in the context of having a significant influence on health outcomes, and economics, in order to estimate the absolute and relative monetary impact of health measures. For this purpose, an expert meeting assessed questions aimed at clarifying the scope and identifying the key issues that should be taken into consideration in developing nutrition economics as a discipline that could potentially address important questions. We propose a first multidisciplinary outline for understanding the principles and particular characteristics of this emerging field. We summarise here the concepts and the observations of workshop participants and propose a basic setting for nutrition economics and health outcomes research as a novel discipline to support nutrition, health economics and health policy development in an evidence and health-benefit-based manner.

Pharmacovigilance of drug allergy and hypersensitivity using the ENDA-DAHD database and the GALEN platform. The Galenda project.

Nonallergic hypersensitivity and allergic reactions are part of the many different types of adverse drug reactions (ADRs). Databases exist for the collection of ADRs. Spontaneous reporting makes up the core data-generating system of pharmacovigilance, but there is a large under-estimation of allergy/hypersensitivity drug reactions. A specific database is therefore required for drug allergy and hypersensitivity using standard operating procedures (SOPs), as the diagnosis of drug allergy/hypersensitivity is difficult and current pharmacovigilance algorithms are insufficient. Although difficult, the diagnosis of drug allergy/hypersensitivity has been standardized by the European Network for Drug Allergy (ENDA) under the aegis of the European Academy of Allergology and Clinical Immunology and SOPs have been published. Based on ENDA and Global Allergy and Asthma European Network (GA(2)LEN, EU Framework Programme 6) SOPs, a Drug Allergy and Hypersensitivity Database (DAHD((R))) has been established under FileMaker((R)) Pro 9. It is already available online in many different languages and can be accessed using a personal login. GA(2)LEN is a European network of 27 partners (16 countries) and 59 collaborating centres (26 countries), which can coordinate and implement the DAHD across Europe. The GA(2)LEN-ENDA-DAHD platform interacting with a pharmacovigilance network appears to be of great interest for the reporting of allergy/hypersensitivity ADRs in conjunction with other pharmacovigilance instruments.

[Therapeutic adherence in chronic obstructive pulmonary disease: A literature review]. / Revue générale sur l'adhésion aux traitements inhalés de la BPCO.

INTRODUCTION: In France, only a small number of studies have focused on therapeutic adherence in patients with chronic obstructive pulmonary disease COPD) despite its impact in terms of multimorbidity. The objective of this literature review was a better understanding of adherence as a whole, and the identification of the effects of non-adherence, in order to optimise patient management. METHODS: A search algorithm was developed to identify all publications on therapeutic adherence in COPD published between 2010 and 2017, in English and in French. The databases used were MEDLINE, ScienceDirect, BDSP, Cochrane and CAIRN. RESULTS: Of the 1551 articles initially identified, 94 were included in the review (65 observational studies, 11 interventional studies and 18 reviews or general overviews). Observational studies considered the predictive factors for adherence/non-adherence, and their consequences. Interventional studies evaluated the efficacy of interventions designed to improve adherence. CONCLUSIONS: Despite major therapeutic progress, the essential problems of COPD management remain. While the treatment armamentarium has expanded in recent years, there is still a great deal of work to be done in simplifying treatment regimens, improving the administration of these treatments and motivating patients to be compliant with them. This review also highlights the need for better physician-patient communication.

Galectin-10 mRNA is overexpressed in peripheral blood of aspirin-induced asthma.

BACKGROUND: In sensitive patients, aspirin is associated with nasal and bronchial inflammation, eliciting local symptoms. Although the disease is clinically well characterized, its physiopathology is incompletely understood and noninvasive procedures, allowing an effective distinction between aspirin-induced asthma (AIA) and aspirin-tolerant asthma (ATA) are missing. OBJECTIVES: The aims of the study were to compare AIA and ATA cohorts for clinical characteristics and to screen peripheral blood for differential mRNA expression. METHODS: Patients experiencing symptoms following aspirin ingestion were considered as aspirin sensitive. Peripheral blood was collected to quantify mRNA expression, using microarray technology and quantitative RT-PCR. RESULTS: Data indicated that AIA and ATA share large number of similarities for clinical phenotype. Screening of mRNA expression using microarray showed an overexpression of galectin-10 mRNA in AIA (AIA/ATA ratio = 1.9, P < 0.05). Results were confirmed using qRT-PCR. A positive correlation was established between microarray and qRT-PCR results for galectin-10 mRNA expression (r = 0.92, P < 0.0001). Finally, qRT-PCR results were validated on a subset of asthmatics and controls, showing an increased expression of galectin-10 mRNA in AIA vs ATA (P < 0.001) and vs controls (P < 0.01). CONCLUSIONS: Our results demonstrate that AIA and ATA remain difficult to distinguish using clinical criteria. Employing two molecular biological methods, we demonstrate that galectin-10 mRNA is overexpressed in AIA, suggesting a novel candidate gene and a potentially innovative pathway for mucosal inflammation in aspirin intolerance.

Patient-reported adverse events under asthma therapy: a community pharmacy-based survey.

The characteristics of patients who report adverse events (AEs) attributed to asthma therapy have been little investigated. Asthma patients aged 18-50 years were surveyed in pharmacies. Patients completed a questionnaire linked to computerized records of dispensed medications. Patients reported all AEs that they attributed to asthma therapy. The correlates of reporting 2+ AEs were identified. Almost 59% of the 1,351 patients (mean age: 37, 56% females) attributed AEs to asthma therapy, and 35% at least two. Most common AEs included tiredness (21.8%) and palpitations (21.1%). Poor asthma control and perception of asthma as a handicap were the major correlates of reporting 2+ AEs (odds ratio (OR)=2.5, 95% confidence interval (CI)=[1.7-3.7] and OR=1.9, 95% CI=[1.4-2.5]). Other significant correlates included age >30 years, female gender, and receiving psychotropic therapy. Inadequate control may partly account for AEs attributed by patients to asthma therapy. Improving patients' education may help to improve acceptability of asthma therapy.

What are the therapeutic alternatives to dextropropoxyphene in France? A prescribers' survey.

About a year after dextropropoxyphene (DXP) withdrawal from the French market, we conducted a survey among members of the French Society of Anesthesia & Intensive Care Medicine (Sfar) and of the French Society of the Study and Treatment of Pain (SFETD) to identify the indications for which this WHO level II analgesic had been prescribed, the prescriber's feedback following withdrawal, and the substitutive analgesics prescribed. DXP had been prescribed by more than 75% of the 430 anaesthesiologists and 230 pain specialists interviewed, mainly for acute and chronic non-cancer pain of moderate intensity. While two thirds of pain specialists were not satisfied with DXP withdrawal, this decision did not affect the majority of anaesthesiologists. In both groups, the main substitutive analgesic was tramadol combined with acetaminophen, while only 24% of prescribers considered acetaminophen alone as a substitute.

[Therapeutic adherence in asthma in France: A general review]. / L'adhésion thérapeutique dans l'asthme en France : revue générale.

INTRODUCTION: Adherence in asthma is a paramount issue of disease management. A general review of the French publications on this topic has been conducted. METHODS: Research equations used for bibliographic databases (MEDLINE, Science Direct, Banque de données en santé publique, Cochrane and Cairn.info) comprised the following keywords: "asthma", "therapeutic adherence" and "France". These publications unrelated to asthma, focused on asthma management without exploring adherence, or those conducted in populations without French patients were excluded. RESULTS: A total of 82 articles have been selected (36 surveys, 4 randomized trials and 42 reviews/syntheses). Whatever the methodology used and publication year, the inadequate therapeutic adherence in asthma was steadily reported, notably for controllers and the quality of use of inhaled devices. CONCLUSION: The present review highlights the sustainability of adherence-related issues in asthma and the need to improve patients' knowledge on asthma and the finality of therapy. It also highlights the need of an improved communication between patients and physicians is also advocated. Further studies with more recent data are desirable to assess changes in disease management of asthma and the impact of potential future corrective interventions.

Long-term achievement of the therapeutic objectives of lipid-lowering agents in primary prevention patients and cardiovascular outcomes: an observational study.

AIMS: Lowering elevated cholesterol levels reduces cardiovascular (CV) morbidity and mortality. Nonetheless, most patients treated with lipid-lowering agents (LLA) do not reach recommended therapeutic objectives. In a setting of primary care in France, we investigated the association between LDL-cholesterol goal attainment and the occurrence of CV events in primary prevention patients with multiple CV risk factors (> or = 3). According to national guidelines, the therapeutic objective (TO) for such patients is an LDL-cholesterol value below 130 mg/dL. METHODS: 579 patients treated with LLA and with LDL-cholesterol values documented at least once a year over a period of at least 3 years (2000-2002) were allocated to three groups based on the number of years the TO was attained during the follow-up period: in all 3 years (TO+++: n=145), only part of the time (TO intermediate: n=256), and never (TO---: n=178). CV events (angina pectoris, myocardial infarction, heart failure, stroke, peripheral artery disease) occurring during the last year of observation (2002) were retrospectively collected. The occurrence risk (OR) of CV events was assessed based on TO status, with a logistic regression model to adjust for baseline differences in CV risk factors. RESULTS: Only a quarter of patients attained TO during all 3 study years. CV events during the third year of observation occurred in 5.5%, 10.5% and 12.9% of patients in the TO+++, TO intermediate and TO--- groups, respectively. Compared with TO+++ patients, the risk of CV events increased significantly in TO intermediate (OR=2.34, 95% CI=[1.01-5.39]) and TO--- patients (OR=2.99, 95% CI=[1.26-7.08]). CONCLUSION: In real practice, a prolonged attainment of TO is rarely observed in high CV risk patients treated with LLA as primary prevention. Therapeutic failure is related to an increased incidence of cardiovascular morbidity. Our data strongly support the need to improve adherence to treatment guidelines to achieve effective cardiovascular prevention.

Asthma-related resource use and cost by GINA classification of severity in three European countries.

BACKGROUND: This study assessed the relationship between asthma burden and asthma severity in France, Italy, and Spain. METHODS: Adult asthmatics, 18-55 years of age, completed a questionnaire while visiting a respiratory physician in 1998 and 1999. Asthma severity was categorized by physicians as intermittent, mild persistent, moderate persistent, or severe persistent according to Global Initiative for Asthma (GINA) guidelines. RESULTS: Totals of 282 patients in France, 500 in Italy, and 296 in Spain entered the study. There were few differences between the three countries in the asthma symptom burden. Most patients with persistent asthma had used inhaled corticosteroids in the previous 14 days. Unexpectedly, 35% (Italy) to 83% (Spain) of patients with intermittent asthma also had used inhaled corticosteroids. In Spain, visits to the emergency department were more frequent (OR 7.0, 95% CI 4.9-10.0 with Italy as reference) and the costs of emergency care in all asthma severity categories were up to 10 times higher than in Italy and France. The frequency of hospitalizations did not differ systematically between the three countries. CONCLUSIONS: Inadequate control of asthma symptoms among patients with severe persistent asthma could not be entirely explained by under-prescribing of asthma medications. The use of inhaled corticosteroids by patients with intermittent asthma might reflect misclassification of asthma severity, possibly due to difficulty in interpreting the GINA guidelines. The relatively high cost of emergency care in Spain does not appear to be related to greater asthma severity or poorer symptom control, but may be a feature of the Spanish health care system.

Medication use and disease control of asthmatic patients in Flanders: a cross-sectional community pharmacy study.

The aim of this study was to describe medication use and disease management of asthmatic patients and to evaluate the usefulness of the Asthma Control Test (ACT) in community pharmacies. In 54 Flemish community pharmacies 166 asthmatic patients were included in the study. At inclusion, the study persons completed a survey to assess subject characteristics, symptoms and asthma attacks, and peak expiratory flow (PEF) was measured. Furthermore, the actual level of asthma control was assessed by ACT, a clinically validated measure of asthma control. Prescribed medicine data of the patients were 1 year retrospectively analysed from the prescriptions. Mean age of the sample was 36.8 year, 23% were smokers. As maintenance treatment, 63% of the patients used a combination product containing an inhaled corticosteroid and a long-acting beta2-agonist in a single inhaler. According to ACT, 49.1% of the patients were insufficiently controlled. Only 4.9% of the patients had a maximal ACT score of 25, indicating complete asthma control; 46.0% of the study population obtained an ACT score between 20 and 24, meaning that their asthma is well controlled. In contrast, 30.7% of the patients had a score between 15 and 19, indicating uncontrolled asthma. In all, 18.4% obtained ACT scores of less than 15, meaning that their asthma was seriously out of control and necessitating referral to their general practitioner or lung specialist. Importantly, the correlation between the self-perceived level of asthma control and the objective assessment of the asthma control level was poor: 82.3% of the patients believed their asthma to be totally or well controlled, while this was the fact for only 50.9% of the patients. In conclusion, the ACT appears to be a useful tool to determine rapidly and accurately the level of asthma control in patients presenting at community pharmacies.

Na+-H+ exchange in the process of glucose-induced insulin release from the pancreatic B-cell. Effects of amiloride on 86Rb, 45Ca fluxes and insulin release.

The effect of amiloride, an inhibitor of Na+-H+ exchange, on intracellular pH (pHi), 86Rb outflow, 45Ca outflow and insulin release from pancreatic rat islets was examined. In the 0.1-1 mM range, amiloride transiently reduced pHi of glucose-deprived islets and allowed glucose to induce a sustained decrease in pHi of the islet cells. Amiloride reproduced the effect of glucose to decrease 86Rb and 45Ca outflow. In the presence of glucose (5.6 mM or more), amiloride (100 microM) acted synergistically with the sugar to reduce K+ outflow, and to stimulate 40Ca inflow and insulin release from perifused islets. These results add strong support to the view that the generation of protons through the metabolism of glucose represents an important step in the process of glucose-induced release. The stimulation by glucose of Na+-H+ exchange apparently masks and even overcomes the glucose-induced decrease in pHi otherwise expected from the increase in catabolic fluxes.

[Deliberate interruptions and changes of dose of inhaled corticosteroids by asthma patients: "a community pharmacy study"]. / Interruptions et changements de posologie des corticoïdes inhalés par les patients asthmatiques: "enquête en pharmacie ".

BACKGROUND: Adherence to inhaled corticosteroids (ICS) remains a major issue for asthma management, even among patients receiving a regular prescription from their doctor. The frequency of deliberate interruption of ICS, and of spontaneous changes of dose, were studied in a population of asthma patients recruited in community pharmacies. METHODS: Asthma patients (aged 18-50) recruited in community pharmacies reported in self-administered questionnaires their spontaneous interruptions and changes of doses of ICS during the past 3 months. The characteristics of patients who interrupted their therapy or who modified the dose were compared with other patients. RESULTS: The studied population included 252 patients (mean age 35 year-old, females: 59%), of whom 62% had inadequately controlled asthma. Among these patients, 25% had interrupted ICS therapy during the past 3 months, while 21% spontaneously changed the dose. The most reported reason for interrupting ICS was the cessation of symptoms (50%). In multivariate analysis, interrupting ICS was mainly associated with inadequate asthma control (OR=3.1, 95% CI 1.5-6.4), while the strongest association with changing ICS doses was the patients' perception of asthma as a concern in their lives (OR=3.2, 95% CI 1.2-8.4). CONCLUSION: These results underline a poor understanding of the purpose of ICS therapy by patients. They also highlight the need of therapeutic education to improve the management of the disease.
