[Impact of an evaluation of the professional practices on the relevance of proton pump inhibitors prescriptions pertinence at the hospital]. / Impact d'une évaluation des pratiques professionnelles sur la pertinence des prescriptions d'inhibiteurs de la pompe à protons à l'hôpital.

INTRODUCTION: Proton pump inhibitors (PPI) are widely prescribed for unrecognized indications, at high a dose and for a long duration, in spite of side effects and numerous drug interactions. In 2009, the HAS (French Health Authority) published recommendations of good prescription but the latter are poorly respected. In this context of over prescription and additional cost for the society, we performed a professional practice evaluation of on the model of the Deming wheel. The objective of this work was to optimize the relevance of the prescriptions of the IPP in two services of internal medicine and geriatrics through an evaluation of the professional practices. All PPI prescriptions introduced in outpatient visits or during hospitalization were analyzed. PATIENTS AND METHODS: Data collection was prospective, over two periods of 2 months and included 163 (first phase), then 139 patients (second phase). An assessment grid of PPI prescriptions was completed by physicians regarding the active substance, the dose, the duration and the indication of the prescription. The relevance of the prescription corresponded to PPI with a conformed indication and duration and to the prescriptions no recommended stopped. Following the first period of data collection, information was given to medical students and physicians on the relevance of their prescriptions with regard to the current recommendations and informative flyers were offered with the aim of improving the practices before the second period of evaluation (second phase). RESULTS: During the first phase, only 25% of the pre-hospital prescriptions and 33% of the hospital prescriptions respected the HAS recommendations. The main indication of the PPI was the prevention of peptic ulcers in a context of associated drug estimated at risk. An improvement of the global relevance of prescription was observed after awareness of the physicians: 26% relevance during the first phase and 60% in the second one (P<0.012). During the second phase, the part of PPI prescriptions introduced at hospital decreased from 33 to 17% and the discontinuation of the not corresponding prescriptions increased from 6 to 33%, with an additional information given to the general practitioner (P<0.001). However, during the second phase, 33% of the prescriptions introduced in hospitalization were always not corresponding and 61% of the not corresponding prescriptions begun in outpatient visits were always pursued on discharge, probably due to the lack of sufficient information to stop the prescription. CONCLUSION: Our study underlines the frequent disrespect of the indications in the prescription of PPI. Interestingly, a professional practices evaluation improved the relevance of the prescriptions with a more frequent withdrawal of the not corresponding exposure and a decrease in global not corresponding prescriptions. Our study suggests that it is crucial to regularly inform physicians on the good prescription of PPI. Patient information focused on the indications and the limited duration of PPI prescription, potentially severe side effects of chronic exposure and on the risk of drug interactions also remains necessary in order to facilitate the stop of the exposure and restrict self-medication.

[Reaction surveillance: organization in public care/hospitals in Marseille]. / Réactovigilance: quelle organisation à l'Assistance publique-Hôpitaux de Marseille ?

For the French Drug Agency (AFSSAPS), the aim of the reactovigilance is to monitor the adverse effects resulting from the use of IVD-MD. More precisely, the goal is to evaluate all incidents and risks that can result in inadequate results or negative effects to the user and therefore for the patient. According to the French Law and before the transposition in the French Law of the European Guideline 98/79/CE, the University Hospital of Marseille has decided to organize its own reactovigilance network. Since 2001, an institutional organization has been set up. For each of the 33 labs of the University hospital one reactovigilant has been nominated as well as one coordinating reactovigilant. Specialized structures have been created: one central committee and one experts group. Standardized operating procedures have been established. The reactovigilance system is also integrated to the vigilance coordination network of the Marseille University Hospital. This organization allows to achieve tracability of all alerts, as well as information and training for the professionals. Four missions are defined: collection and management of all incidents IVD-MD-related; diffusion of AFFSAPS and industrials alerts to all labs in order to take appropriate measures; Tracability of alerts and incidents in all labs and in central committee, tracability of reactives according to French guidelines (GBEA). For the first 10 months of 2002, 46 alerts have been forwarded to all lab's correspondants. In the same period, one real adverse event has been locally notified and after analyse will be forwarded to the AFSSAPS. All these factors should contribute to the health professionals interest and participation in reactovigilance activities.

[Factors influencing the appropriation of clinical guidelines by physicians]. / Facteurs influençant l'appropriation des recommandations médicales par les médecins.

DEFINITION: Clinical guidelines (CG) constitute a means to facilitate the decision-making process, defining what is and is not appropriate in fields concerned with public health matters or unregulated practices. METHOD: A bibliographical review has been conducted on factors likely to influence physicians' compliance to CG. These factors involve physicians, the guidelines themselves and the actions taken to encourage their implementation. FACTORS RELATED TO PHYSICIANS: In physicians' attitudes, we find not only their propensity to ask for help, to admit mistakes and weakness, but also their wish for continuing medical education. Practicing in an establishment or group consulting offices enhances their awareness of CG. The use of CG and the consequences of their implementation, as well as legal or financial concerns, increase physicians' confidence in the benefits of CG for themselves and their patients. FACTORS RELATED TO GUIDELINES: Clinical guidelines should be issued by multi-professional groups, among which there should be recognized experts and day-to-day specialists. Their access should be easy and their updating frequent. The adaptation to the individual conditions of local practices is essential. THE IMPORTANCE OF IMPLEMENTATION: Once established, an intensive dissemination and active appropriation policy should be enacted. On the other hand, it is unlikely that passively diffused and non-updated CG will be adopted by newly qualified or long-established physicians installed in routine practice. Account must also be taken of the nature of certain CG, considered restrictive or coercive, and the targeted physician's attitudes and practicing habits - which is still unusual in France.

[Accreditation knowledge acquired by personnel in the Marseille hospital]. / Connaissances sur l'accréditation acquises par le personnel des Hôpitaux de Marseille.

Sensitization and educational training programmes are important pre-requisites in order to ensure the understanding of the issues at stake in the accreditation process. According to the preparatory research involved for this work, there has been no study published nor is there any documentation available on such a topic, specifically on carrying out the sensitization process to successful completion. The aims of this study are to evaluate the effectiveness of the sensitization phase and to refine general recommendations to serve as a guide for health institutions and their communications policies. A transversal randomised study was conducted through the distribution of a questionnaire to 107 health professionals from 23 clinical services in the public hospital system in Marseille. The results demonstrate that the knowledge about accreditation seems to be well integrated, with only 7 of the professionals being unaware of the accreditation programme, and 58% of them associating the accreditation process with an administrative procedure. Grouping the staff's responses according to professional category has shown to have almost no influence on the results. The level of overall knowledge is greater in more highly trained personnel (p < 0.05), but there was a poor level of knowledge regarding the internal organisational structures that existed. 75% of the health professionals thought that communication about accreditation was insufficient. The study authenticated the positive benefits of communication and identified a certain number of stumbling blocks to avoid. Several recommendations are proposed.

[Morphological aspect of embryos obtained after fertilization in vitro for male factor or ICSI]. / Aspect morphologique des embryons obtenus après une fécondation in vitro pour indication masculine ou ICSI.

OBJECTIVE: In order to study the eventual impact on fertilization and embryo characteristics of the microinjection procedure we compared the quality of the embryos obtained by ICSI with those of in vitro fertilization with male factors (MF IVF). MATERIAL AND METHODS: One hundred thirty-four cycles of IVF treatment (group 1) were selected with oligoasthenozoospermia according to WHO criteria with a total number of motile spermatozoa between 500,000 and 1 million. One thousand eighty-eight mature oocytes and 486 embryos were obtained. One hundred forty-three cycles of intracytoplasmic sperm injection (group 2) were performed in couples whose in vitro fertilization was imparticable because of extreme sperm impairment. One thousand one hundred forty-seven mature oocytes were injected and 626 embryos were obtained. RESULTS: In group 1, the pregnancy rate per embryo transfer and the implantation rate were respectively 22.7% and 12.3%. In group 2, the pregnancy rate per embryo transfer was 37.1% and the implantation rate was 17%. The statistical analysis of the embryos obtained in the two different groups did not demonstrate any difference in the distribution of the more regular and less fragmented embryos (group A) and those of the more irregular and fragmented embryos (group B). No statistical difference was demonstrated in the chronology of the division of these embryos (groups 1 and 2). CONCLUSION: The pregnancy rate by cycle and by transfer reported by ICSI (p < 0.003 and p < 0.015 respectively) could be related to a significantly higher mean number of transferred embryos (2.65 vs 2.02) in probable relation with a higher cleavage rate (p < 0.00001).

[Controlled analgesia in a burn patient: fentanyl sparing effect of clonidine]. / Analgésie contrôlée par le patient brûlé: effet d'épargne de fentanyl par la clonidine.

OBJECTIVE: To determine the sparing effect of clonidine (C) on fentanyl (F) demand in burned patients under PCA. STUDY DESIGN: Prospective, randomized, double blind study versus placebo. PATIENTS: Twelve consecutive patients with mean burn surface area of 20 +/- 9%, studied between the third and the eighth day post-burn. METHODS: F was delivered by a PCA pump (bolus: 1 mg.kg-1). In the morning, burn patients received additional F (5 mg.kg-1) before hydrotherapy. After randomisation, C or placebo (P) were alternatively infused over 24 hours. Demands for F during the morning, the afternoon and the evening were noted. Pain scores were measured on a visual analogic scale. In eight patients, plasma levels of F (pF) were iteratively measured. Heart rate, arterial pressure, respiratory rate and SpO2 were monitored. RESULTS: Analgesic demands were 19.5/day under P and 9.5 under C (P < 0.0001). Pain reoccurred for pF of 4.1 under C vs 5.7 under P (P < 0.05) with same pain scores in the two groups. After a pain stimulus, pain scores were lower under F, despite lower pF (P < 0.05). Arterial pressure and heart rate were significantly lowered during the first hour of C infusion. CONCLUSION: Doses of F and pF required to reach analgesia were very high. Adding C decreases by 50% the F demand and lowers pF. Minor haemodynamic effects were observed during the first hour of C infusion.
