Introduction
The objective of this study was to estimate and to characterize the actual patterns of triptan use and overuse in France using a drug reimbursement database.
Methods
We included all ...people covered by the French General Health Insurance System (GHIS) from the Provence-Alpes-Côte-d’Azur (PACA) and Corsica administrative areas who had at least one dispensed dose of triptans between May 2010 and December 2011. All dispensed doses of triptans, migraine prophylactic treatment and psychotropic medications were extracted from the GHIS database. Triptan overuse was defined as triptan use >20 defined daily doses (DDD) per month on a regular basis for more than three consecutive months. Risk of overuse was assessed using logistic regression adjusted for gender and age.
Results
We included 99,540 patients who had at least one prescription of a triptan over the 20 months of the study. Among them, 2243 patients (2.3%) were identified as overusers and received 20.2% of the total DDD prescribed. Twelve percent of overusers and 6.9% of non-overusers were aged more than 65 years (OR: 1.81). Overusers did not have a greater number of prescribers and pharmacists than non-overusers. They were more frequently prescribed a prophylactic medication for migraine treatment (56.8% vs 35.9%, OR: 2.36), benzodiazepines (69.9% vs 54.7%, OR: 1.93) and antidepressants (49.4% vs 30.2%, OR: 2.33).
Conclusions
This work suggests that triptan overuse may be due to insufficient prescriber awareness of appropriate prescribing. The off-label prescription of triptans among the elderly necessitates investigating their cardiovascular risk profile in this sub-group.
Purpose: The aim of this study was to describe the extent of methylphenidate (MPH) abuse and characterize its patterns by following several cases involving intravenous administration of crushed MPH ...tablets. Methods: First, a drug reimbursement database (covering 4 million inhabitants) was explored to assess the magnitude of MPH abuse among the general population, and second, a specific study based on individuals with drug dependence was performed to describe abusers' characteristics (n = 64), patterns of abuse and clinical implications. Results: From 2005 to 2011, the number of patients who were dispensed MPH at least once increased by 166%. The patients with ‘deviant' patterns of MPH consumption were mainly male adults with opiate maintenance treatment reimbursements. MPH abusers had precarious living conditions. Half of them consumed MPH daily by intravenous route and reported amphetamine-like effects (cardiovascular events, weight loss, psychiatric adverse events). Conclusion: Given the increase of MPH use, it is important to warn the scientific community about possible MPH abuse, especially in individuals with drug dependence. This study has facilitated public health intervention and dissemination of information related to MPH abuse among health care professionals at local and national levels.
IntroductionLong-term glucocorticoid therapy is the leading cause of secondary osteoporosis. The management of glucocorticoid-induced osteoporosis (GIOP) seems to be inadequate in many European ...countries.ObjectiveTo evaluate the rate of screening and treatment of GIOP.DesignInformation was collected from a national public health-insurance database in our geographic area of Provence-Alpes-Côte-d'Azur and in Corsica, from September 2009 through August 2011.PatientsWe identified participants aged 15 years and over starting glucocorticoid therapy (≥7.5 mg of prednisone equivalent per day during at least 90 days consecutive). This cohort was compared with an age-matched and sex-matched population that did not receive glucocorticoids.Main outcome measuresBone mass, prescription of bone antiresorptive medication and use of calcium and/or vitamin D treatment.ResultsWe identified 32 812 patients who were prescribed glucocorticoid therapy, yielding 1% prevalence. Incidence of glucocorticoid therapy was 2.8/1000 inhabitants/year. Males represented 44%, the mean age was 58 years. The median prednisone-equivalent dose was 11 mg/day (IQR 9–18 mg/day). 8% underwent bone mass measurement. Calcium and/or vitamin D, and bisphosphonates were prescribed in 18% and 12%, respectively. Results were lower for the control population: 3% underwent bone mass measurement and 3% received bisphosphonate therapy. The rates of osteodensitometry and treatments were higher in women over 55 years of age than in men and women 55 years of age and younger, and also when glucocorticoid therapy was initiated by a rheumatologist versus other physician specialty.ConclusionsThe management of GIOP remains very inadequate, despite the availability of a statutory health insurance system. Targeted interventions are needed to improve the management of GIOP.
The aim of the study was to identify and to characterize patients with Alzheimer's disease or related dementia describing antipsychotics and other psychotropic expositions.
The study was performed, ...in 2010, based on Provence-Alpes-Côte d'Azur region (PACA)-Corse Alz cohort included patients with dementia, with chronic condition 'Alzheimer disease or related disease' and/or had at least one delivery of Alzheimer's specific treatment, registered in the General Health Care System. Psychotropic drugs were extracted according anatomical, therapeutical and chemical code. Chronic exposure defined as more than 3 consecutive deliveries.
Among 34 696 included patients, 26.9% were men and 68.8% were 80 years old and more. Among them, 26% received at least one antipsychotic medication, with a chronic exposition estimated around 61.3%. Antidepressant and anxiolytic were consumed respectively by 47% and 45.3% of patients. Risperidone was the most used antipsychotic (11.2%). The Health care use (hospitalizations, nurses and physicians visits) was significantly higher among patients with antipsychotics.
Antipsychotics use in patients with dementia remains high. The follow up of this regional cohort would be helpful to identify the impact of guidelines on the prescription and the care of patients with dementia.
To assess the national market penetration rate (PR) of generic high-dosage buprenorphine (HDB) in 2008 and its evolution since their marketing (2006), and making a point for each dosage and at ...regional level.
Retrospective study over data using national and regional health reimbursement database over three years (2006-2008).
In 2008, the generic HDB's national MPR was 31%. The PR for each dosage were 45% for 0.4 mg, 36% for 2 mg and 19% for 8 mg. The (PR) based on Defined Daily Dose (DDD) was 23% in 2008, 15% in 2007 and 4% in 2006. In 2008, at the regional level, disparities were observed in the adjusted penetration rate from 15% in Île de France to 39% in Champagne Ardennes Lorraine.
The national PR of generic HDB has increased. There are differences in MPR in terms of dosage and area. However, this PR is still low (in 2008, 82% of the delivered drugs are generics).
