Pristinamycin-induced arthralgia and myalgia: Analysis of the French Pharmacovigilance Database.

INTRODUCTION: Pristinamycin is an antibiotic of the streptogramin family; few adverse effects of this drug are reported, only cutaneous and digestive ones. Arthralgia and myalgia may however be observed although not mentioned in the summary of product characteristics. OBJECTIVE: Description and analysis of cases of pristinamycin-induced arthralgia and/or myalgia registered in the French database of pharmacovigilance. METHOD: We carried out a targeted search of the database, selecting case patients presenting with arthralgia and muscle pain and excluding those associated with sensitivities or allergies to pristinamycin. RESULTS: We retrieved 15 case patients of pristinamycin-induced arthralgia and myalgia. Pristinamycin was the only potentially incriminated drug for seven case patients. CONCLUSION: Although not serious, this adverse effect deserves to be better known by physicians to optimize therapeutic management.

[Drug-induced pancreatitis. A review of French spontaneous reports]. / Pancréatites d'origine médicamenteuse. Revue des notifications spontanées en France.

PURPOSE: Identify the main pharmacological classes inducing pancreatitis using spontaneous reports recorded in the French pharmacovigilance database (FPVD). METHODS: Cases of pancreatitis recorded in FPVD between January 1st 1985 and December 31st 2013 were selected using the 2001 consensus conference criteria of the French High Health Authority. RESULTS: During this period, 2975 observations were selected with 1151 fulfilling criteria of drug-induced pancreatitis (i.e. 0.22% of total notifications in the FPVD). According to ATC classification, the pharmacological classes most frequently found were antiretroviral, analgesic, lipid-lowering, immunosuppressive and insulin secreting drugs. For some drugs (metformin, omeprazole, etc.) pancreatitis was "unlabelled" in the summary of product characteristics. CONCLUSION: This review allows to identify the main drug classes currently involved in spontaneous reporting of pancreatitis in France.

Frailty and Pain: Two Related Conditions.

Frailty is a multidimensional syndrome, involving functional, nutritional, biological and psychological aspects. This condition, defined as a decreased resistance to internal and external stressors, is predictive of adverse health outcomes, including disability and mortality. Importantly, the frailty syndrome is usually considered a reversible condition, thus amenable of specific preventive interventions. Persistent pain in older adults is very common and has multiple determinants. This symptom represents a determinant of accelerated aging. In the present paper, we discuss available evidence examining the association between these two conditions. Despite the high prevalence of these two conditions and their shared underlying mechanisms, our search only retrieved few relevant studies. Most of them reported a relationship between pain (or analgesics consumption) and different operational definitions of frailty. Pain may represent a relevant risk factor as well as a potential target for interventions against the frailty syndrome, but further studies are needed.

Potentially inappropriate drug prescription in the elderly in France: a population-based study from the French National Insurance Healthcare system.

BACKGROUND: Inappropriate prescribing is a known risk factor for adverse drug event occurrence in the elderly. In various countries, several studies have used insurance healthcare databases to estimate the national prevalence of potentially inappropriate medications (PIM) in the elderly, as defined by explicit PIM lists. Recently, a representative sample of the French National Insurance Healthcare database, known as the "Echantillon Généraliste des Bénéficiaires" (EGB), was created, making it possible to assess the quality of drug prescription in France. Our objective was to evaluate the prevalence and the regional distribution of PIM prescription in the elderly aged 75 years and over in France, using the French PIM list and the EGB database. METHODS: The list of drugs reimbursed to patients aged 75 years and over from 1 March 2007 to 29 February 2008 was extracted from the EGB. Drugs were classified as inappropriate using the French PIM list. A PIM user was defined as a person receiving at least one PIM reimbursement during the study period. Interregion variability was estimated from logistic regression. RESULTS: In 53.6% (95% CI: 53.0-54.1) of the elderly aged 75 years and over, at least one PIM was given during the study period. The three main drug groups identified were cerebral vasodilators (19.4%), drugs with antimuscarinic properties (19.3%), and long half-life benzodiazepines (17.8%). There was an important disparity in PIM prescription among the French regions. In 14 out of 22 regions, the risk of PIM prescription was significantly elevated. This geographical variation differed for the different drug groups. CONCLUSION: PIM prescription in the elderly is a major and worrying problem in France. As in other countries, recent accessibility of the National Insurance Healthcare database makes it possible to create local indicators that the regional health agencies could use to manage public health policy in closer alignment to the needs of the patients within each French region.

[Potentially inappropriate medications in the elderly: a list adapted to French medical practice]. / Médicaments potentiellement inappropriés aux personnes âgées: intérêt d'une liste adaptée à la pratique médicale française.

Drug induced adverse effects are frequently encountered in geriatrics. Their occurrence can be limited by an adapted prescription. Potentially inappropriate medications are drugs with an unfavourable benefit to risk ratio when other safer or more efficient therapeutic alternatives are available. An expert consensus allowed us to establish a new list of potentially inappropriate medications for people aged 75 or over, taking into account French prescribing habits. The drugs or the drug-classes proposed in this list are, generally speaking, and when possible, to be avoided in the elderly, but can be prescribed at times, under special clinical conditions, provided that the benefit to risk ratio is assessed. The French list proposed here could be considered as (i) an epidemiological tool for evaluating the quality of drug prescription in geriatrics and as (ii) a prescription guide suggesting an alternative treatment whenever a therapeutic alarm is raised. This guide could be used both as a base for the education of prescribers and as a way of increasing patients awareness. This French list should be kept up-to-date so as to remain adapted to the evolution of the knowledge on the effect of drugs in the elderly and of the pharmaceutical market.

[Quality of medical records in the "Medical Information System Program": application of the lot quality assurance sampling method]. / Qualité des données P.M.S.I. au CHU de Limoges: application de la méthode L.Q.A.S.

BACKGROUND: The aim of this study was to validate a new method of quality control of medical records of the "Medicalisation of Information System Program" (P.M.S.I.) in Limoges university hospital. METHODS: Lot quality assurance sampling (L.Q.A.S.), developed to meet industrial quality control needs, has been applied. This method allows to give an opinion on the quality of a lot from a sample randomised in this lot. Ten hospital units have been randomised. During three months, these medical units have recoded ten medical units abstracts (R.U.M.) which were randomised each month within their stays. If five or more R.U.M. had been modified on Principal Diagnosis (D.P.), Associated Significant Diagnosis (D.A.S.) or Diagnosis Related Group (D.R.G.), the lot was rejected. The hospital unit had then less 70% R.U.M. of good quality (alpha=5%). The global errors rates were compared to the results of usually performed quality control (1998). RESULTS: Nine hospital units were included. Hospital units which already had a low quality rate during the 1998 quality control had also an insufficient quality by L.Q.A.S. method. Among these, 33.7 [CI(95%): 21.6-45.8] R.U.M. have been modified. Medical units had a poorer data quality than surgical ones. No statistically significant difference was shown between 1998 errors rates and L.Q.A.S. rates, except for D.P. (p=0.002). CONCLUSION: L.Q.A.S. is easy to apply, could be repeated more frequently than usual controls, and allows to detect hospital units which require a faster action. This process could be applied to P.M.S.I., in which the search of quality is necessary because of the new cost model which includes secondary D.R.G.
