Factors associated with persistence of cholinesterase inhibitor treatments in the elderly.

PURPOSE: To identify factors associated with one-year persistence of cholinesterase inhibitor (ChI) treatments. METHODS: A retrospective cohort study was performed using the reimbursement database of the Echantillon Généraliste des Bénéficiaires, a 1/96(e) representative sample of subjects affiliated to the French National Healthcare Insurance System. Among this, patients who initiated a ChI treatment between 1 January 2004 and 31 December 2005 and for whom 1 year of follow-up in the database after treatment initiation was available were identified. One-year persistence of ChI treatment was defined as an ongoing treatment without dispensing interval exceeding 60 consecutive days during the 12 months following treatment initiation. Drug switches were not considered as treatment discontinuation. A multivariate logistic regression was conducted to identify, among patients characteristics (sociodemographic, drug uses), factors associated with one-year persistence of ChI treatments. RESULTS: Among the 942 patients who initiated a treatment with ChI during the study period, 72.4% were women; mean age was 79.6 years (SD = 7.4). Patients used eight other different drugs in median (Inter-Quartile Range: 5-11); 63.7% used psychotropics, 63.6% used cardiovascular drugs. One-year persistence of ChI treatments was estimated at 45.3%. Persistence of ChI treatments was lower in patients aged 80 years and over (OR = 0.74, 95%CI: 0.57-0.96); it was higher in patients using antidepressants at ChI treatment initiation (OR = 1.38, 95%CI: 1.05-1.82). CONCLUSIONS: One-year persistence of ChI treatment was estimated at 45.3% in this French sample. To optimize persistence of ChI treatment in the demented, patients poorly symptomatic and/or aged over 80 years should be especially monitored.

[The shared medical record, a digital health record for all]. / Le dossier médical partagé, un carnet de santé numérique pour tous.

In July 2016, the National Health Insurance re-launched the shared medical record, a tool for sharing information between health professionals and patients. Its use has been growing among doctors for more than a year now, and more healthcare institutions are rolling it out.

The CADEUS study: burden of nonsteroidal anti-inflammatory drug (NSAID) utilization for musculoskeletal disorders in blue collar workers.

AIM: The aim of this study was to compare patterns of utilization of NSAIDs for musculoskeletal disorders (MSD) by occupation in a general employed population. METHODS: This was a secondary analysis of the CADEUS cohort study on 5651 actively employed patients, who submitted at least one claim for the reimbursement of a NSAID dispensation for a MSD between August 2003 and July 2004, in the French National Healthcare Insurance database. Questionnaires were sent to prescribing physicians to obtain diagnoses and the medical history, and to patients for their occupation, height and weight and smoking status. Multivariate logistic regression was used to study the determinants of a heavy use of NSAIDs defined as 'over four dispensations in one year with less than two months between any two'. RESULTS: Factors associated with heavy use of NSAIDs were age (Odds ratio (OR): 1.8 (ten years), 95% confidence interval (CI): 1.6-1.9), osteoarthritis (versus back pain) (OR: 1.8, 95% CI: 1.5-2.1), body mass index (superior to 30) (OR: 1.8, 95% CI: 1.5-2.2), and occupation (blue collar versus white collar workers) (OR: 1.4, 95% CI: 1.2-1.6). Blue collar workers also had a 20% higher prevalence of 5-year history of dyspepsia. No difference was observed between sexes or in the use of COX-2 selective inhibitors between occupations. CONCLUSION: Factors associated with occupational constraints that contribute to the severity of MSDs, may explain the heavier use of NSAIDs among blue collar workers in spite of a concurrent and past medical history of adverse reactions to this type of medication.

Prevalence of cholinesterase inhibitors in subjects with dementia in Europe.

PURPOSE: To evaluate the prevalence of cholinesterase inhibitor (ChI) treatment in subjects with dementia in European countries. METHODS: We studied the prevalence of treatment in subjects with dementia among European countries in 2004 (Belgium, France, Germany, Italy, the Netherlands, Poland, Portugal, Spain and the United Kingdom) by using estimates of prevalence of dementia and of ChI treatments according to sales and reimbursement data. RESULTS: In 2004, estimated prevalence of ChI use among subjects with dementia ranged from 3.0% in the Netherlands to 20.3% in France. It was 17.5% in Spain, 6.7% in the UK and 5.9% in Italy. Donepezil was used by more than 60% of patients using a single ChI and represented almost 50% of reimbursements for patients that had used at least two different ChIs during the year. Galantamine and rivastigmine were respectively used by 22 and 18% of subjects using a single drug and 27 and 23% of reimbursements for patients that had used at least two different ChIs. Nevertheless, different patterns of use were found for individual countries. CONCLUSIONS: Prevalence of treatment by ChIs among subjects with dementia remains weak and varies greatly across Europe. Differences in reimbursement rates and health policies could partly explain these variations, as ChIs could have failed to convince health authorities because the outcomes considered for trials are not used by clinicians in their everyday practice. If donepezil was highly predominant across countries, variations in rivastigmine and galantamine importance could reflect local market specificities.

Management of lower urinary tract symptoms related to benign prostatic hyperplasia in real-life practice in france: a comprehensive population study.

BACKGROUND: Male lower urinary tract symptoms (LUTS) are one of the most treated diseases, but little is known about patient trajectories in current clinical practice. OBJECTIVE: To describe the dynamic treatment patterns of LUTS presumably due to benign prostatic obstruction (BPO). DESIGN, SETTINGS, AND PARTICIPANTS: All prescriptions of α1-adrenergic receptor blocking agents (α1-blockers), 5α-reductase inhibitors (5-ARIs), and phytotherapy, and all surgeries related to BPO performed in France from 2004 to 2008 were identified using two distinct administrative claim databases maintained by the National Health Insurance system that covers the entire population. After linking the two data sets, all consecutive treatment events were analyzed for each patient. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Drug prescription details were assessed for each year, region, and prescriber qualification. Medical treatment initiation, interruption, evolution, and events after surgical management (hospital stay, reoperation, complication rates, and subsequent medical prescriptions) were also investigated. RESULTS AND LIMITATIONS: Overall, 2 620 269 patients were treated within 5 yr, with important geographic variations. Medical treatment was interrupted for approximately 16% of patients. The α1-blockers were prescribed most frequently, but phytotherapy surprisingly accounted for 27% of all monotherapies and 54% of all combination therapies. General practitioners and urologists (92% and 3.7% of overall prescribers, respectively) exhibited a similar prescription profile. Treatment initiation was medical in 95.4% of cases, consisting primarily of monotherapy using α1-blockers (60.3%), phytotherapy (31.8%), or 5-ARIs (7.9%). Treatment was modified at extremely high rates within 12 mo of initiation (8.7%, 14.6%, and 12.9%, respectively). The median hospital stay for surgical management was far higher than in clinical trials. Long-term surgical complications and reoperation rates favored open prostatectomy. Incidence of pharmacologic treatment after surgery was as high as 13.8% at 12 mo. CONCLUSIONS: This unique dynamic evaluation of clinical practice revealed unexpected results that contrast with previously published evidence from clinical trials. This approach may merit monitored and targeted measures to improve the level of care in the field.
