[Educational needs and implantable medical devices: How to meet the expectations of patients with coronary stents and heart valves?] / Besoins éducatifs et dispositif médical implantable : comment répondre aux attentes des patients porteurs de stents coronaires et valves cardiaques ?

At the Grenoble Alpes University Hospital Center, patients with cardiovascular disease have the opportunity to participate in a therapeutic education program in the cardiac rehabilitation department. The objective of this study is to analyze the educational needs of patients with coronary stents and heart valve prostheses. Using an exploratory qualitative method, semi-structured research interviews were conducted with 22 patients and an inductive thematic analysis was performed. We found that emergency surgery does not facilitate the assimilation of information in comparison with a scheduled procedure. The image of the "repaired heart" creates a cognitive conflict with the chronicity imposed by secondary preventive monitoring, a particularity of the implantable medical device. Patients feel that the information they receive is sometimes too voluminous and not adapted to their current needs. Thus, we propose an individualized support model based on the respect of temporality and on the psycho-behavioral functioning of the patient.

[Involvement of hospital pharmacy technician for expanding medication reconciliation process in France: Actors' willingness and opinions]. / Implication du préparateur en pharmacie hospitalière dans le déploiement de la conciliation des traitements médicamenteux en France : représentations et engagement des préparateurs.

OBJECTIVES: Medication reconciliation is widely promoted by international health authorities. Its expansion requires human resources, which are limited and unequally distributed among health care facilities. Recent international studies support the involvement of pharmacy technician in the medication reconciliation process but his role remains unstructured in France. We aimed to assess pharmacy technicians' opinions and willingness to be involved in the medication reconciliation process expansion and to identify the levers and barriers of the project. METHODS: A field study was conducted among health facilities of our territory hospital group. Semi-structured interviews were carried out with different pharmacy technicians. Data were analyzed using a qualitative thematic analysis approach. RESULTS: Overall, 12 pharmacy technicians from 5 hospitals were interviewed and almost all assumed their rightful place in the medication reconciliation process (n=11), with a view to revaluating tasks. For all pharmacy technicians, the main barriers to participate in medication reconciliation were the lack of time and training. The spread of a "patient culture", the supervision by pharmacists, the desire to be part of the care team in the ward and additional training requests were major levers of change. CONCLUSIONS: Pharmacy technicians' role in expanding medication reconciliation process is legitimate and must be standardized in France. The deployment of the project requires to be formalized within a territory and should consider and develop local organisations.

Validation of a tool for reporting pharmacists' interventions in everyday community pharmacy.

WHAT IS KNOWN AND OBJECTIVE: The French Society of Clinical Pharmacy (SFPC) asked a group of experts to adapt the SFPC hospital pharmacists' interventions reporting tool for use in community pharmacy practice. This study aimed to develop and validate a tool for the routine reporting of pharmacists' interventions in French community settings. METHODS: Two groups of community pharmacists coded reports of 60 typical pharmacists' interventions. One group was "experts" (n = 4) who had participated in the development of the tool (internal validation) and the other were "external" community pharmacists (n = 6), naïve to the tool (external validation). The Kappa coefficient was used to assess the inter-reliability of classification between participants. A 4-level Likert scale was used to evaluate ease of use and acceptability. RESULTS AND DISCUSSION: The tool we developed for recording and classifying PIs has 19 items; 11 non-ordered categories describing drug-related problems; and 7 items describing interventions. Two tables of definitions were provided to help community pharmacists in the classification. The mean κ statistic was (i) 0.63 for experts and 0.73 for external community pharmacists in categorizing drug-related problems and (ii) 0.69 for experts and 0.75 for external community pharmacists in categorizing interventions. WHAT IS NEW AND CONCLUSION: A specific tool for the documentation of pharmacists' interventions in community pharmacies is now available in French. Besides being useful to describe pharmacists' interventions in studies in community settings, it can be used to document the pharmaceutical patient record and to support the traceability process.

[We have to stop talking about "non compliant" patients but rather about patients with difficulties of medication adherence]. / Il nous faut arrêter de parler du patient « non observant ¼ à ses traitements mais plutôt d'un patient présentant des difficultés d'adhésion médicamenteuse.

Medication adherence can be defined as the link between "what the patient implements" and "what the patient and his doctor have decided together after negotiating without constrains". This definition should be put into perspective with the chronology of the disease and the way the patient experiences it. Counselling actions should always be adapted to the situation and negotiated with the patient, all along the process of care. This article proposes a model for this process and offers options pour tailored counselling. Key elements for pharmacist's practice are: simplify the prescription; communicate with the patient according to his stage of acceptation of the disease; get adequate training for motivational interviewing.

Description and analysis of hospital pharmacies in Madagascar.

OBJECTIVE: Madagascar's health care system has operated without formal hospital pharmacies for more than two decades. The gradual integration of pharmacists in public hospitals since 2012 will allow the structuring of this field. This study was conducted to characterize the current situation regarding all aspects relating to the general functioning of hospital pharmacies and the services provided. METHODS: This qualitative research used semi-structured interviews. Interviewees' perceptions about the general organization and functioning of hospital pharmacies and details on services provided were collected. The 16 interviewees were Ministry of Health staff members involved in hospital pharmacy, hospital directors, medical staff members and hospital pharmacy managers. Interviews were recorded, translated into French if conducted in Malagasy, and fully transcribed. Verbatim transcripts were coded according to the themes of hospital pharmacy and topical content analysis was performed. RESULTS: The principal issue perceived by interviewees was the heterogeneity of the system in terms of technical and financing management, with a main impact on the restocking of pharmaceutical products. The drug supply chain is not under control: no internal procedure has been established for the selection of pharmaceutical products, the quantification of needs is complex, stock management is difficult to supervise, a standard prescription protocol is lacking, dispensing is performed by unqualified staff, no pharmaceutical preparation is manufactured in the hospitals and administration occurs without pharmaceutical support. CONCLUSIONS: Progressive structuring of efficient hospital pharmacy services using the Basel statements for the future of hospital pharmacy is urgently needed to improve health care in Madagascar.

[How to act when an alpha-blocker is associated with a potent inhibitor of CYP3A4]. / Conduite à tenir en cas d'association d'un alpha-bloquant et d'un inhibiteur puissant du cytochrome 3A4.

OBJECTIVE: Combination of alpha-blockers with potent CYP3A4 inhibitors is either contra-indicated or not recommended. We searched data supporting this classification and guiding prescribers when such an interaction occurs. METHODS: We analyzed reports published by the French agency for drug safety, reference books and performed search in databases of pharmacokinetics studies and case or case series related with these interactions. RESULTS: The classification of the potential severity of these interactions defined by the French agency for drug safety evolved over time. Our literature search did not identify any cases or case series reporting serious clinical consequences of such interactions and no pharmacoepidemiological studies on the association between alpha-blockers and inhibitors of CYP3A4. The content of the summaries of product characteristics indicate that the combination of ketoconazole with alfuzosin, silodosin and tamsulosin increases the area under the curve of the alpha-blocker 3 fold. CONCLUSION: Data demonstrating the clinical consequences of an association between alpha-blocker and a potent CYP3A4 inhibitor are lacking. The 3 fold increase of the area under the curve for alfuzosin, silodosin and tamsulosin associated with ketoconazole while the association with the two first is contra-indicated and is not recommended with the third raises questions. This lack of data leaves doctors and pharmacists in a situation of uncertainty on how to proceed when such an interaction occurs.

[Identification of knowledge deficits of pharmacy students at the beginning of the fifth year of pharmacy practice experience: Proposals to change the content of academic programs]. / Identification des lacunes de connaissances des étudiants en filière officine débutant le stage de 5(e) année : propositions pour modifier le contenu de l'enseignement.

INTRODUCTION: In France, community pharmacy students performed a hospital pharmacy practice experience during the 5th year of the university curriculum. The purpose of a part of the content of the academic teaching program delivered before this practice experience is to prepare the students for their future hospital activities. It should enable them for the practical use of knowledge in order to improve pharmacotherapy, laboratory diagnosis and monitoring of patients' care. The aim of this study was to show if there are gaps in this program. METHODS: Fourteen students performing their clerkship in a teaching hospital were invited to highlight these gaps when they were gradually immersed in the pharmaceutical care. They did so under the careful observation of hospital pharmacist preceptors. These practitioners referred to professional guidelines, documentary tools used in daily clinical practice and publications supporting their pharmaceutical care practices. RESULTS: Shortcomings and gaps identified were: how to communicate with other healthcare professionals and the content of verbal exchanges, how to conduct a patient-centered consultation, documentation tools required for relevant pharmacist' interventions, codification of pharmacist's interventions, risks related to drug packaging and benefit risk assessment of health information technologies. DISCUSSION: These gaps represent a handicap by delaying the process that led to move from student to healthcare professional. Hospital pharmacist preceptors have to fill in these gaps before engaging students in pharmaceutical care. CONCLUSION: These results invite to revise partly the content of the academic teaching program delivered before the 5th year hospital pharmacy practice experience.

Trends in pharmacists' medication order review in French hospitals from 2006 to 2009: analysis of pharmacists' interventions from the Act-IP© website observatory.

WHAT IS KNOWN AND OBJECTIVES: The French Society of Clinical Pharmacy has developed a website, named Act-IP©, enabling hospital pharmacists to document and analyse pharmacists' interventions (PIs) proposed during medication order review when a drug-related problem is detected. This study analyses PIs documented in Act-IP© and assesses factors associated with physicians' acceptance of PIs. METHODS: PIs documented into Act-IP© over a 30-month period were analysed. Independent predictors of physicians' acceptance were assessed using multiple logistic regression. RESULTS AND DISCUSSION: A total of 34,522 PIs were registered by 201 pharmacists working in 59 hospitals. PIs were mostly related to 'dose adjustment' (25%), 'drug discontinuation' (20%) and 'drug switch' (19%). Of the 43,343 medications involved, 28% targeted drugs acting on the central nervous system, 17% anti-infective drugs and 16% cardiovascular drugs. Sixty-eight per cent of PIs were accepted by physicians (15% refusals and 17% non-assessable). Physicians' acceptance was significantly associated with 1/ drug group: antineoplastics and immunomodulators (OR = 2.29, CI 95[1.94-2.69]), anti-infectives (OR = 1.19, CI 95 [1.11-1.28]); 2/ type of intervention: drug switch (OR = 1.54, CI 95 [1.43-1.65]), drug discontinuation (OR = 1.38, CI 95 [1.29-1.48]), administration modality optimization (OR = 1.19, CI 95 [1.11-1.29]), addition of a new drug (OR = 1.12, CI 95 [1.00-1.24]); 3/ ward specialty: paediatrics (OR = 1.83, CI 95 [1.24-2.70]) and intensive care (OR = 1.34, CI 95 [1.10-1.64]); 4/ level of pharmacist integration in the ward: higher when the pharmacist is regularly in the ward compared with occasionally (OR = 0.74, CI 95 [0.70-0.79]) or never (OR = 0.68, CI 95 [0.60-0.75]) present. WHAT IS NEW AND CONCLUSION: This study highlights the role of routine pharmacist review of medication orders to prevent drug-related problems and gives new insights for a successful collaboration between physicians and pharmacists.

[Pharmacists' interventions conducted by hospital pharmacists on psychotropic drugs pharmacotherapy]. / Interventions pharmaceutiques émises par les pharmaciens sur les médicaments psychotropes.

INTRODUCTION: The French Society of Clinical Pharmacy (SFPC) through the special interest group "standardization and optimization of clinical pharmacy activities" stated that the study of pharmacists' interventions (PIs) conducted during prescription analysis was a priority. The SFPC developed an internet website named Act-IP(®) (http://www.sfpc.eu/fr/) where French speaking pharmacists were able to document PIs using a normalized codification. The objective of this study was to analyze medication-related problems linked to psychotropic drugs in hospital and to investigate PIs performed during prescription analysis. MATERIALS AND METHODS: This is a multicenter, retrospective, observational study using PIs involving psychotropic medications recorded between September 2006 and February 2009 on the Act-IP(®) website. RESULTS: Four thousand six hundred and twenty PIs recorded by 165 pharmacists in 57 hospitals were related to psychotropic drugs. Patients concerned by these drug-related problems were 64 years old on average. Seven categories of medication-related problems represented more than 69% of PIs (1.1-Non Conformity of the drug choice compared to the formulary; 4.1 Supratherapeutic dose; 5.3 Therapeutic redundancy; 6.2 Drug interaction (all levels of severity); 7.0 Adverse drug reaction; 8.3 Inappropriate drug form; 8.5 Inappropriate timing of administration). The PIs related to 9.2 Patient's non compliance, 2.0 Untreated indication and 3.2 Length of the treatment too short were infrequent (less than 1%). The most common type of intervention was the dose adjustment. Almost 45% of these PIs involved Zopiclone or Zolpidem prescription in elderly patients. Seven hundred and nine drug interactions were identified by pharmacists. The most common type of drug interaction considered the risk of cardiac arrhythmias due to antipsychotic medications. One hundred and thirty-three PIs concerned adverse drug reaction. The most frequent adverse drug reactions were a fall (36 PIs), hemorrhage/bleeding (32 PIs), drowsiness (12 PIs) and extrapyramidal syndrome (12 PIs). Antidepressant drugs were the greatest pharmacological class concerning adverse drug reaction. The overall acceptance rate was 57%. Eight hundred and seventy-four PIs (19%) were refused and 1111 (24%) were non-assessable. DISCUSSION: PIs avoids drug-related problems, such as the polyprescription of benzodiazepine or supratherapeutic dose. However, few PIs concern compliance to therapy or polyprescription of antipsychotic drugs. These two categories of medication-related problems are known to be an issue in mental health therapy. The lack of guidelines describing mental health pathology (such as the HAS guideline) is an obstacle for performing evidence-based PIs. The lack of information describing the context of the prescription is a limitation of this study. In order to improve their practice, pharmacists have to focus more on the context in which patients are evolving, and to take into account its entire situation based on Anglo-Saxon approaches. A second way is to identify clinical settings where PIs are useful and to describe PIs needed. Doctors and pharmacists should get together and talk about these clinical situations and PIs, because some may be misunderstood or disapproved by prescribers. This collaboration could take the form of a thesaurus combining clinical situation and PIs. CONCLUSION: It appears important for pharmacists to show their daily involvement in the quality of medical care. This feedback on medication problems encountered and PIs proposed should help prescribers to identify clinical situations at risk. Nevertheless, this study also suggests that progress is possible. Dialogue must allow pharmacists and physicians to delete misunderstandings about their practices.

[In vitro study of the flow duration of antibiotics solutions prepared in elastomeric infusion devices: effect of cold storage for 3 to 7days]. / Étude in vitro de la durée d'écoulement de solutions antibiotiques préparées dans des diffuseurs portables élastomériques : effet du stockage au froid pendant trois à sept jours.

INTRODUCTION: Within the cystic fibrosis patients' home care, EMERAA network ("Together against Cystic fibrosis in Rhone-Alpes and Auvergne") organizes parenteral antibiotics cures at home prepared in elastomeric infusion devices by hospital pharmacies. However, patients and nurses found that the durations of infusion with these devices were often longer than the nominal duration of infusion indicated by their manufacturer. This study aimed to identify the potential different causes in relation to these discordances. MATERIAL AND METHODS: Three hundred and ninety devices of two different manufacturers are tested in different experimental conditions: three antibiotics each at two different doses, duration of cold storage (three days or seven days) or immediate tests without cold storage, preparation and storage of the solution in the device (protocol Device) or transfer in the device just before measurement (protocol Pocket). RESULTS: All tests highlighted a longer flow duration for devices prepared according to the protocol Device versus the protocol Pocket (P=0.004). Flow duration is increased in the case of high doses of antibiotics with high viscosity such as piperacilline/tazobactam. DISCUSSION: The results of this in vitro study showed the impact of: (1) the time between the filling of the device and the flow of the solution; (2) cold storage of elastomeric infusion devices; (3) concentration of antibiotics and therefore the viscosity of the solution to infuse. CONCLUSION: It is therefore essential that health care teams are aware of factors, which may lead to longer infusion durations with these infusion devices. When the additional time for infusion remain acceptable, it should be necessary to inform the patient and to relativize these lengthening compared to many benefits that these devices provide for home care.

Illness representation and treatment beliefs in liver transplantation: an exploratory qualitative study.

BACKGROUND: The objective of this study was to gain detailed insight concerning liver transplanted patients' representations about transplantation, graft rejection and immunosuppressive drugs to adapt the educational follow-up. PATIENTS AND METHODS: Semi-structured interviews were conducted with 8 patients. Each interview was recorded and fully transcribed. The verbatim was first coded according to the themes of the Common Sense Model and an inductive approach for the remaining text. RESULTS: Transplantation is perceived both as a recovery and a new chronic condition. Participants feel powerless in the face of the risk of graft rejection. This risk is perceived as out of control as it is not associated with specific symptoms and external causes. The individual knowledge gained about transplantation relies on real-life experience shared between patients. Many participants feel anxiety. It responds to stress caused by immunosuppressant medication intake, routine check-ups, potential side effects and chronicity of immunodepression. Messages stressing the importance of the tacrolimus in the medication therapy are strengthened by a pre-discharge pharmaceutical consultation. DISCUSSION AND CONCLUSIONS: This study suggests that healthcare providers should systematically seek to determine illness representations to optimize the educational follow-up. The patient education program for liver transplanted patients should include three types of intervention: individualized education, behavioral intervention and psychological support. It should provide a support for stress management and acceptance of the new chronic condition. The involvement of a clinical pharmacist is relevant.

Overdosed paracetamol (acetaminophen) prescriptions and subsequent pharmacist interventions in French hospitals.

INTRODUCTION: Little is known about the manner in which hospital pharmacists intervene for overdosed paracetamol prescriptions. The aim of this retrospective study was to describe the number and nature of pharmacists' interventions (PIs) for overdosed paracetamol adult prescriptions in hospitals. METHODS: We studied PIs that had been documented by pharmacists on the French Society of Clinical Pharmacy website tool between 2007 and 2010. We identified PIs that were related to paracetamol-containing prescriptions of one brand name only (type 1) particularly for patients with body weight ≤ 50 kg who were prescribed 4 g/day, and PIs that concerned the co-prescription of two paracetamol-containing products (type 2). RESULTS: Among 60 hospitals, seven did not report any paracetamol overdose-related PIs. Of the 53 hospitals that had at least one PI, 16 did not report any type 1 PIs. Bodyweight, liver disease, cirrhosis and chronic alcoholism were absent recorded criterion by most of the hospitals included in this study. DISCUSSION: Previously published studies have highlighted that the most frequent PIs are type 1, especially for patients whose body weight is ≤ 50 kg. We observed a broad variability in the number or type of PI that were related to overdosed paracetamol prescriptions compared with the total of all recorded types of PI. These data suggest that a significant number of hospital pharmacists are unaware of the risks that adult patients with low body weight are exposed to when receiving four grams paracetamol/day over several days. CONCLUSION: Pharmacist educational programs are needed.

[How can we evaluate medication adherence? What are the methods?]. / Comment évaluer l'adhésion médicamenteuse? Le point sur les méthodes.

INTRODUCTION: Identifying the difficulties of the patient towards following his medication regimen remains complex for the healthcare provider. This can be explained by the multidimensional character of medication adherence and, actually, the evaluation of this phenomenon. The objective of this work was to review the various methods to measure medication adherence. METHODS: We performed a search on PubMed completed by a manual one. RESULTS: Two types of measure are described. The "direct" methods are based on the measurement of the level of medicine or metabolite in blood or urine, measurement of biologic markers in blood or measurement of physiologic or clinical markers. The "indirect" methods are represented by the analysis of the administrative databases (prescription, rate of prescription refills); pill counts; electronic medication monitors; the self-reported measures by the patient or his close relations (questionnaires, diaries, interviews); the opinion of the healthcare provider. DISCUSSION: None of these tools supplants the others, each having limits either of feasibility, or reliability. In the end, it is the crossing of the information stemming from these various equipments that allows an idea on the adherence behavior of the patient and especially, dimensions on which he is most in trouble. CONCLUSION: The identification of these difficulties can allow the healthcare provider to develop behavioral and organizational skills tailored to the patient follow-up.

Patients' knowledge about paracetamol (acetaminophen): a study in a French hospital emergency department.

UNLABELLED: Paracetamol is the most widely used analgesic and antipyretic drug. In France, little is known concerning patients' knowledge and beliefs about paracetamol. OBJECTIVE: To determine how much outpatients attending an emergency department know about paracetamol. METHOD: A semi-structured questionnaire was applied to patients consulting for non-severe medical or traumatic conditions. RESULTS: Thirty-three (45%) of 73 participating patients knew that paracetamol was the active ingredient of the medication they used to reduce pain and/or fever. Three patients thought 2g was the maximum recommended single dose; 25% thought that a delay between two doses ≤ 3 hours was recommended and 15% thought the maximum daily dose was > 4 g. While 8% cited liver toxicity as a side effect, 38% did not believe an excessive dose could be fatal. Two patients correctly answered all questions and five gave no correct answer. DISCUSSION: Outpatients attending an emergency department (ED) have poor knowledge about paracetamol. This situation is disturbing and our results may serve as an eye opener to healthcare professionals. They emphasize the need for research programs with the following objectives: a) to determine the actual content of the message delivered by healthcare professionals; b) to study conditions under which this message is issued; c) to analyze how patients understand key messages and what their behavioral response is. CONCLUSION: In ED patients, the level of knowledge about paracetamol is insufficient to ensure its safe use in ambulatory care. Further studies are needed to determine the causes and to permit better patient education.

Prescriptions analysis by clinical pharmacists in the post-operative period: a 4-year prospective study.

BACKGROUND: Clinical pharmacists can help prevent medication errors. However, data are scarce on their role in preventing medication prescription errors in the post-operative period, a high-risk period, as at least two prescribers can intervene, the surgeon and the anesthetist. We aimed to describe and quantify clinical pharmacist' intervention (PIs) during validation of drug prescriptions on a computerized physician order entry system in a post-surgical and post-transplantation ward. We illustrate these interventions, focusing on one clearly identified recurrent problem. METHODS: In a prospective study lasting 4 years, we recorded drug-related problems (DRPs) detected by pharmacists and whether the physician accepted the PI when prescription modification was suggested. RESULTS: Among 7005 orders, 1975 DRPs were detected. The frequency of PIs remained constant throughout the study period, with 921 PIs (47%) accepted, 383 (19%) refused and 671 (34%) not assessable. The most frequent DRP concerned improper administration mode (26%), drug interactions (21%) and overdosage (20%). These resulted in a change in the method of administration (25%), dose adjustment (24%) and drug discontinuation (23%) with 307 drugs being concerned by at least one PI. Paracetamol was involved in 26% of overdosage PIs. Erythromycin as prokinetic agent, presented a recurrent risk of potentially severe drug-drug interactions especially with other QT interval-prolonging drugs. Following an educational seminar targeting this problem, the rate of acceptation of PI concerning this DRP increased. CONCLUSION: Pharmacists detected many prescription errors that may have clinical implications and could be the basis for educational measures.

[So that therapeutic education becomes for the pharmacist a working posture]. / Pour que l'éducation thérapeutique du patient devienne pour le pharmacien une posture de travail.

Considering the increasing complexity of the management of the chronic pathologies (invalidating, requiring an adaptation from the patient, an integration in his everyday life, a global care, in clinical, therapeutic, economic and psychosocial aspects), the pharmacist has to build up a partnership with the others healthcare professionals. This practice can be described following Pharmaceutical care process: reconciliation (what information on drugs intake upon patient's admission); validation of prescription (what critical points? what points of optimization of the therapeutics?); pharmaceutical follow-up (which clinical indicators, biological, psychosocial (…) to assess benefits/risks ratio of the drug regimen?); negotiation with the patient of a schedule of drug intake; definition of an therapeutic education plan. therapeutic patient education, defined by a set of recent texts (August 2, 2010) (relating to qualifications and methodological framework for this activity) must be understood by the pharmacist, not as a new practice but as a logical extension of his service to the chronic patient, requiring pharmaceutical expertise (to be recognized as legitimate over drug therapy), an active listening posture and guidance tailored to each patient (to develop teaching skills), networking with others partners on information around the patient.

[Thinking differently the patient medication compliance: from an injunctive posture to a working alliance between the patient and the healthcare provider: concepts and determinants]. / Penser autrement l'observance médicamenteuse : d'une posture injonctive à une alliance thérapeutique entre le patient et le soignant - Concepts et déterminants.

Patient compliance is a dynamic behaviour, which varies in time and in shape. The impact of poor adherence is medical (loss of immediate benefits and/or long-term) and economic (direct and indirect costs). Adhering and remaining engaged in the daily drug treatment appear to be a challenge for the chronic patient. In this context, we propose as a first step, to describe the evolution of the wording around adherence. This evolution is underlying the paradigm shifts behind this concept and opens new areas for action. Based on this new angle of view that represents the patient's adherence with its drug therapy, we detail the various factors influencing medication adherence categorized into five dimensions: illness, medication, demographic and socio-economic, patient and/or patient support and care system. The impact of these factors is described and explanatory models underlying explicited. Understanding of the issues underlying adherence to drug treatment will help consider further personalized interventions, multi-faceted response to the multiplicity of influencing factors.

Overdosed prescription of paracetamol (acetaminophen) in a teaching hospital.

INTRODUCTION: Paracetamol is the most commonly used analgesic and antipyretic. Reviews of hospital use of paracetamol are scarce. Little is known about the appropriateness of the dose of paracetamol prescribed for hospitalized adults. The aim of this study was to report on the nature and the frequency of the overdosed prescription of paracetamol observed in adult patients over a 4.5-year period in a teaching hospital. METHODS: Prescription analysis by pharmacists was performed once a week in six medical and three surgical departments and daily in a post-emergency unit. In cases of prescription error, the pharmacist notified the physician through an electronic alert when a computerized prescription order entry system was available or otherwise by face-to-face discussion. For each drug-related problem detected, the pharmacists recorded relevant details in a database. RESULTS: From October 2006 to April 2011, 44,404 prescriptions were reviewed and 480 alerts related to the overdosed prescription of paracetamol were made (1% of analyzed prescriptions). The extent of errors of dosage was within the intervals [90-120 mg/kg/d] and greater than 120 mg/kg/d for 87 and 11 patients respectively, who were prescribed a single non-combination paracetamol containing product. Sixty alerts concerned co-prescription of at least two paracetamol containing products with similar frequency for computerized (1.4/1000) or handwritten (1.2/1000) prescriptions. DISCUSSION: Prescriptions of paracetamol for hospitalized adults frequently exceed the recommended dosage. CONCLUSION: These results highlight the need for increased awareness of unintentional paracetamol overdose and support the initiation of an educational program aimed at physicians and nurses.

[Opportunities for medication errors and pharmacist's interventions in the context of computerized prescription order entry: a review of data published by French hospital pharmacists]. / Opportunités d'erreurs médicamenteuses et interventions pharmaceutiques dans le cadre de la prescription informatisée : revue des données publiées par les pharmaciens hospitaliers français.

INTRODUCTION: Computerized prescription order entry (CPOE) is accelerating in France. CPOE has been shown to reduce the occurrence of some medication errors, but evidence of a beneficial effect on clinical outcomes remains limited. In some cases, new error types have arisen with its use. The aim of this study was to investigate the French data on the nature and frequency of medication errors opportunities generated by the computer use, which led pharmacists to alert prescribers. METHODS: We performed a search on PubMed and CAT-INIST databases completed by a manual one. RESULTS: Ten publications, 11 abstracts and three personal communications were analysed. As part of the analysis of computerized prescriptions, the rate of pharmaceutical interventions due to CPOE ranges from 5.9 to 35% depending on the study. Duplicate orders, unit errors, the use of free text, parameterization flaws and poor usability of software are probably the root of many prescribing errors. Errors generated by the tool can have serious potential consequences. DISCUSSION: Pharmacist's interventions due to CPOE are common. It is not known whether variability of the percentage of pharmacist's interventions is due to software used or to conditions by witch studies were carried out. With implementation of CPOE in hospital, pharmacists must acquire new knowledge and new skills in order to prevent prescription errors generated by these tools and its misuse. CONCLUSION: Studies are urgently needed in order to identify the safest tools and to discard the most dangerous.
