Brief Risk Communication for Emergency Department Patients With Sustained Asymptomatic Hypertension.

INTRODUCTION: Sustained asymptomatic hypertension in ED patients is a powerful predictor of chronic uncontrolled hypertension. In this study, we assess the feasibility of using a storyboard video and communicating real-time cardiovascular imaging results on blood pressure control and primary care engagement. METHODS: This was a prospective observational exploratory sub-study. Following Institutional Review Board approval (#18-00197), 20 English-speaking adults in an urban emergency department with an initial blood pressure ≥160/100 mm Hg and a second blood pressure ≥140/90 mm Hg were enrolled. Patients watched a 60-second storyboard video about uncontrolled hypertension in the ED setting, featuring racially and ethnically diverse avatars. They then received a real-time bedside echocardiogram. Emergency nurses communicated the echocardiogram results using a standard script and advised follow-up within 2 weeks after discharge. Patient characteristics, blood pressure control, primary care engagement, and acceptability of the intervention were assessed at baseline, 12 weeks, and 24 weeks post-discharge. RESULTS: All 20 enrolled patients (mean age 55, 70% female, and 95% from underrepresented groups [30% Black, 50% Hispanic, and 15% Black and Hispanic]) exhibited subclinical heart disease on echocardiograms. Blood pressure control improved from baseline (systolic 166 mm Hg, diastolic 97 mm Hg) to 24 weeks (systolic 137 mm Hg, diastolic 78 mm Hg). Seventy percent of patients engaged with primary care post-discharge, and the intervention had high acceptability (94.8% approval). DISCUSSION: The Brief Risk Communication for ED patientswith sustained asymptomatic hypertension study demonstrates the feasibility and acceptability of using a brief video and real-time cardiovascular imaging for risk communication in the emergency department. Future research will build on these findings with a larger, more comprehensive study.

Multi-organ point-of-care ultrasound for COVID-19 (PoCUS4COVID): international expert consensus.

COVID-19 has caused great devastation in the past year. Multi-organ point-of-care ultrasound (PoCUS) including lung ultrasound (LUS) and focused cardiac ultrasound (FoCUS) as a clinical adjunct has played a significant role in triaging, diagnosis and medical management of COVID-19 patients. The expert panel from 27 countries and 6 continents with considerable experience of direct application of PoCUS on COVID-19 patients presents evidence-based consensus using GRADE methodology for the quality of evidence and an expedited, modified-Delphi process for the strength of expert consensus. The use of ultrasound is suggested in many clinical situations related to respiratory, cardiovascular and thromboembolic aspects of COVID-19, comparing well with other imaging modalities. The limitations due to insufficient data are highlighted as opportunities for future research.

CLEAR: A Novel Approach to Ultrasound Equipment Homeostasis.

Protocols for the sanitation and maintenance of point-of-care ultrasound (US) equipment are lacking. This study introduces the CLEAR protocol (clean, locate, energize, augment supplies, and remove patient identifiers) as a tool to improve the readiness of US equipment, termed US equipment homeostasis. The state of US equipment homeostasis in the emergency department of a single academic center was investigated before and after implementing this protocol, with an improvement in outcomes. These findings demonstrate that the CLEAR protocol can improve US homeostasis. CLEAR can function as a teaching tool to promote homeostasis as well as a checklist to assess compliance.

Variability in Interpretation of Cardiac Standstill Among Physician Sonographers.

STUDY OBJECTIVE: Cardiac standstill on point-of-care ultrasonography has been widely studied as a marker of prognosis in cardiac arrest. Return of spontaneous circulation has been reported in as few as 0% and as many as 45% of patients with cardiac standstill. When explicitly documented, the definition of cardiac activity in these studies varied from any slight change in echogenicity of the myocardium to any kinetic cardiac activity. We hypothesize that the variability in research definitions of cardiac activity may affect interpretation of video clips of patients in cardiac arrest. The goal of this study is to assess the variability in interpretation of standstill among physician sonographers. METHODS: We surveyed physician sonographers at 6 conferences held at 3 academic medical centers in the Greater New York area. Survey respondents were allotted 20 seconds per slide to determine whether each of 15 video clips of patients in cardiac arrest were standstill or not. Data were collected anonymously with radio frequency remotes. RESULTS: There were 127 total participants, including faculty, fellows, and resident physicians specializing in emergency medicine, critical care, and cardiology. There was only moderate interrater agreement among all participants (α=0.47). This lack of agreement persisted across specialties, self-reported training levels, and self-reported ultrasonographic expertise. CONCLUSION: According to the results of our study, there appears to be considerable variability in interpretation of cardiac standstill among physician sonographers. Consensus definitions of cardiac activity and standstill would improve the quality of cardiac arrest ultrasonographic research and standardize the use of this technology at the bedside.

Seeing Is Believing: Evaluating a Point-of-Care Ultrasound Curriculum for 1st-Year Medical Students.

PROBLEM: Point-of-care ultrasound has been a novel addition to undergraduate medical education at a few medical schools. The impact is not fully understood, and few rigorous assessments of educational outcomes exist. This study assessed the impact of a point-of-care ultrasound curriculum on image acquisition, interpretation, and student and faculty perceptions of the course. INTERVENTION: All 142 first-year medical students completed a curriculum on ultrasound physics and instrumentation, cardiac, thoracic, and abdominal imaging. A flipped classroom model of preclass tutorials and tests augmenting live, hands-on scanning sessions was incorporated into the physical examination course. Students and faculty completed surveys on impressions of the curriculum, and all students under-went competency assessments with standardized patients. CONTEXT: The curriculum was a mandatory part of the physical examination course and was taught by experienced clinician-sonographers as well as faculty who do not routinely perform sonography in their clinical practice. OUTCOME: Students and faculty agreed that the physical examination course was the right time to introduce ultrasound (87% and 80%). Students demonstrated proper use of the ultrasound machine functions (M score = 91.55), and cardiac, thoracic, and abdominal system assessments (M score = 80.35, 79.58, and 71.57, respectively). Students and faculty valued the curriculum, and students demonstrated basic competency in performance and interpretation of ultrasound. Further study is needed to determine how to best incorporate this emerging technology into a robust learning experience for medical students.

Point-Of-Care Ultrasound Diagnosis of Intravascular Air After Lower Extremity Intraosseous Access.

BACKGROUND: Vascular air embolism is a rare but potentially deadly phenomenon. Early diagnosis allows providers to initiate measures aimed at preventing further air entry, preventing the migration of air to the lungs, and mitigating the hemodynamic effects of pulmonary air embolism. CASE REPORT: An emergency physician used point-of-care ultrasound to identify intravascular air before embolization to the pulmonary vasculature. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Bedside ultrasound can be used as a tool for early diagnosis of intravascular air. Emergency physicians should be aware of the typical sonographic manifestations of intravascular air and the initial steps in treating vascular air embolism.

Evaluation of an Obstetric Ultrasound Curriculum for Midwives in Liberia.

OBJECTIVES: Point-of-care ultrasound is an effective tool for clinical decision making in low- and middle-income countries, but lack of trained providers is a barrier to its utility in these settings. In Liberia, given that midwives provide most prenatal care, it is hypothesized that training them in prenatal ultrasound through an intensive condensed training course is both feasible and practical. METHODS: This quantitative prospective study of preobservational and postobservational assessment evaluated a 1-week ultrasound curriculum consisting of 4 modules, each comprising a didactic component, a practical session, and supervised patient encounters. A knowledge-based pretest and presurvey addressing prior use and comfort were administered. At the intervention conclusion, identical posttests and postsurveys were administered with an objective structured clinical examination (OSCE). The test, survey, and OSCE were repeated after 1 year. All scores and responses were tabulated, and qualitative analysis with paired t tests was performed. RESULTS: Thirty-one midwives underwent intervention and written evaluation, with 14 followed up at 1 year. Seventeen underwent the OSCE, with 8 retained at 1 year. There was a significant increase between pretest and immediate and 1-year posttest scores (36.6% versus 90% and 66%; P < .001) but no difference between immediate and 1-year posttest scores (90% versus 66%; P > .05). Average overall comfort using ultrasound increased from presurvey to immediate postsurvey scores (from 1.8 to 3.8; P< .001) and remained higher at the 1-year postsurvey (1.8 to 3.4; P< .05). Overall OSCE scores remained high from immediately after the OSCE to 1 year after the OSCE (78% to 55%; P > .05). CONCLUSIONS: Midwives in Liberia had very low baseline knowledge and comfort using ultrasound. A 1-week curriculum increased both short- and long-term knowledge and comfort and led to adequate overall OSCE scores that were retained at 1 year.

Recruitment of emergency department patients to a prospective observational study.

BACKGROUND: The dynamic environment of the emergency department (ED) poses unique challenges to the execution of well-designed research. There is limited investigation into the viability of studies conducted in the ED. This paper offers a systematic evaluation of our recruitment of emergency patients for a prospective observational research study, shedding light on the intricate landscape of research feasibility within the ED setting. RESULTS: Research coordinators dedicated 2816.83 h to screening, recruiting, and enrolling patients between June 2018 and September 2023, having to stop recruitment twice due to financial constraints and the COVID-19 pandemic. 485 patients were approached and 84 of them were enrolled, resulting in a 31.94% enrollment rate, with approximately 2.8 participants recruited per month. Of those enrolled, 77 completed all study endpoints. Most participants were Hispanic (n = 44; 52.3%) and/or Black (n = 37; 44%), middle-aged (µ = 51.7 years), and female (n = 48; 57.1%). Participant recruitment was challenged by competing mindsets, the COVID-19 pandemic, and high staff turnover. CONCLUSIONS: Recruiting emergency patients for a prospective observational study is feasible given adequate staffing and financial resources. Standardizing feasibility assessments for the recruitment of patients in the emergency department is important to the success of future study.

A brief educational intervention is effective in teaching the femoral nerve block procedure to first-year emergency medicine residents.

BACKGROUND: Hip fractures are a painful condition commonly encountered in the emergency department (ED). Older adults in pain often receive suboptimal doses of analgesics, particularly in crowded EDs. Nerve blocks have been utilized by anesthesiologists to help control pain from hip fractures postoperatively. The use of nerve stimulator with ultrasonographic guidance has increased the safety of this procedure. OBJECTIVES: We instituted a pilot study to assess the ability of Emergency Medicine (EM) resident physicians to effectively perform this procedure after a didactic and demonstration session. METHODS: First-year EM residents from three urban training programs underwent a 1-h didactic and hands-on training session on the femoral nerve block (FNB) procedure. A written pretest was used to assess baseline knowledge; it was administered again (with test items randomized) at 1 and 3 months post training session. A critical actions checklist (direct observation of procedure steps via simulated patient encounter) was used to assess the residents after the training session and again at 3 months. RESULTS: A total of 38 EM residents were initially evaluated. Thirty-three successfully completed 1-month and 3-month written test evaluations; 30 completed all written and direct observation evaluations. The mean written pretest scores were 66% (SD 9); post-test 92% (SD 5), 1-month 74% (SD 8), and 3-month 75% (SD 9). After initial training, 37 of 38 (97%) residents demonstrated competency (completing ≥ 15 of 19 critical actions) in the FNB procedure determined via direct observation. At 3 months, 25 of 30 residents (83%) continued to retain 85% of their initial critical action skills, and 3 of 30 (10%) saw an improvement in their proficiency. CONCLUSION: A 1-h training and demonstration module yielded high competency rates in residents performing critical actions related to the FNB; these skills were well maintained at 3 months. An ongoing study will attempt to correlate this competency with procedures performed on patients.

International consensus conference recommendations on ultrasound education for undergraduate medical students.

OBJECTIVES: The purpose of this study is to provide expert consensus recommendations to establish a global ultrasound curriculum for undergraduate medical students. METHODS: 64 multi-disciplinary ultrasound experts from 16 countries, 50 multi-disciplinary ultrasound consultants, and 21 medical students and residents contributed to these recommendations. A modified Delphi consensus method was used that included a systematic literature search, evaluation of the quality of literature by the GRADE system, and the RAND appropriateness method for panel judgment and consensus decisions. The process included four in-person international discussion sessions and two rounds of online voting. RESULTS: A total of 332 consensus conference statements in four curricular domains were considered: (1) curricular scope (4 statements), (2) curricular rationale (10 statements), (3) curricular characteristics (14 statements), and (4) curricular content (304 statements). Of these 332 statements, 145 were recommended, 126 were strongly recommended, and 61 were not recommended. Important aspects of an undergraduate ultrasound curriculum identified include curricular integration across the basic and clinical sciences and a competency and entrustable professional activity-based model. The curriculum should form the foundation of a life-long continuum of ultrasound education that prepares students for advanced training and patient care. In addition, the curriculum should complement and support the medical school curriculum as a whole with enhanced understanding of anatomy, physiology, pathophysiological processes and clinical practice without displacing other important undergraduate learning. The content of the curriculum should be appropriate for the medical student level of training, evidence and expert opinion based, and include ongoing collaborative research and development to ensure optimum educational value and patient care. CONCLUSIONS: The international consensus conference has provided the first comprehensive document of recommendations for a basic ultrasound curriculum. The document reflects the opinion of a diverse and representative group of international expert ultrasound practitioners, educators, and learners. These recommendations can standardize undergraduate medical student ultrasound education while serving as a basis for additional research in medical education and the application of ultrasound in clinical practice.

Portable ultrasound for remote environments, Part I: Feasibility of field deployment.

BACKGROUND: In field medical operations, rapid diagnosis and triage of seriously injured patients is critical. With significant bulk and cost constraints placed on all equipment, it is important that any medical devices deployed in the field demonstrate high utility, durability, and ease of use. When medical ultrasound was first used in patient care, machine cost, bulk, and steep learning curves prevented use outside of the radiology department. Now, lightweight portable ultrasound is widely employed at the bedside by emergency physicians. The techniques and equipment have recently been extrapolated out of the hospital setting in a wide variety of environments in an effort to increase diagnostic accuracy in the field. OBJECTIVES: In this review, deployment of lightweight portable ultrasound in the field (by emergency medical services, military operations, disaster relief, medical missions, and expeditions to austere environments) is examined. The feasibility of field deployment and experiences of clinicians using ultrasound in a host of environments are detailed. In addition, special technological considerations such as telemedicine and machine characteristics are reviewed. CONCLUSIONS: The use of lightweight portable ultrasound shows great promise in augmenting clinical assessment for field medical operations. Although the feasibility of the technology has been demonstrated in certain medical and trauma applications, further research is needed to determine the utility of ultrasound use for medical illness in the field.

Portable ultrasound for remote environments, part II: current indications.

BACKGROUND: With recent advances in ultrasound technology, it is now possible to deploy lightweight portable imaging devices in the field. Techniques and studies initially developed for hospital use have been extrapolated out of the hospital setting in a wide variety of environments in an effort to increase diagnostic accuracy in austere or prehospital environments. OBJECTIVES: This review summarizes current ultrasound applications used in out-of-hospital arenas and highlights existing evidence for such use. The diversity of applications and environments is organized by indication to better inform equipment selection as well as future directions for research and development. DISCUSSION: Trauma evaluation, casualty triage, and assessment for pneumothorax, acute mountain sickness, and other applications have been studied by field medical teams. A wide range of outcomes have been reported, from alterations in patient care to determinations of accuracy compared to clinical judgment or other diagnostic modalities. CONCLUSIONS: The use of lightweight portable ultrasound shows great promise in augmenting clinical assessment for field medical operations. Although some studies of diagnostic accuracy exist in this setting, further research focused on clinically relevant outcomes data is needed.

The use of CFD modelling to optimise measurement of overflow rates in a downstream-controlled dual-overflow structure.

The measurement of the flow through complex combined sewer overflow structures in the frame of automated monitoring remains difficult. In this paper, a methodology based on the use of computational fluid dynamics (CFD) modelling in order to improve the instrumentation of a downstream-controlled dual-overflow structure is presented. The dual-overflow structure is composed of two combined sewer overflows (CSOs) connected by a rectangular channel and controlled by a downstream gate located at the entry of the Meyzieu waste water treatment plant (close to Lyon, France). The analysis of the CFD results provides: (i) a better understanding of the interaction between the two CSOs--that means the hydraulic operation, the hydrodynamic behaviour, the backflow effect--and (ii) an ability to optimise the location of the water depth sensor. The measured water depth is used to assess the overflow rate by means of a numerical relationship. Uncertainties are also assessed.

[Evaluation of prescription practices of long acting injectable risperidone in French hospitals]. / Enquête des prescriptions de rispéridone injectable à libération prolongée dans neuf centres hospitaliers du réseau PIC.

INTRODUCTION: Atypical antipsychotics or antipsychotics of second generation are still recommended by guidelines for primary use in the treatment of psychotic disorders because of their better neurologic safety and efficacy. However, they require daily dosing, thus compromising their overall efficacy whereas conventional depot neuroleptics provide constant pharmacologic treatment but induce extrapyramidal adverse effects and poor efficacy on negative symptoms. Long acting injectable risperidone (LAIR) is the first long-acting second-generation antipsychotic. Registered in October 2003 and launched in March 2005 in France thanks to Kane et al.'s and Fleischhacker et al.'s reference studies, it was supposed to provide the advantages of conventional long acting formulations of antipsychotics over those of an atypical agent. OBJECTIVES AND METHODS: The aims of this study, with the description of the prescription practices of LAIR in naturalistic conditions, were to assess the place of this new drug in psychotic medication, with the efficiency value measured by treatment discontinuation rate and analysis of the reasons for discontinuation, and to assess whether the prescriptions practices are or not in adequacy with guidelines and reglementation. In June 2005, we conducted a one-year naturalistic non-randomised open-label study in nine French psychiatric hospitals, members of the PIC network: were included all the patients who received LAIR every 2 weeks, between July 1st 2005 and November 30th 2005. RESULTS: Prescriptions of 216 patients were examined for 1 year. LAIR was used off label for 15% of the patients. Ninety-two percent of patients were hospitalized at the beginning of the treatment while 72% of the treated patients had dropped out one year after the first injection. Regarding the nature of previous antipsychotic treatments prescribed in the last three months before the first injection of LAIR: 31% patients had received a first generation antipsychotic, half of which had received a depot antipsychotic of first generation and 69% had received a second-generation antipsychotic, among which half had received oral risperidone. The principal reason noted by the clinicians for starting the new formulation was non-observance with anterior treatments. However, oral antipsychotic treatment preceding the first injection was used less than 4 weeks for one third of the patients. When this treatment was oral risperidone, average posology at the first injection was 6.7 ± 2.4 mg per day; it was 7.4 ± 2.1 mg per day for the patients who received the higher dose of LAIR (50 mg/2 weeks). So, it seems that some patients were not sufficiently stabilized by their antipsychotic before the beginning of the long acting treatment. The result was a significant rate of treatment discontinuations (53%) in the following year, principally caused by the withdrawal of the patient's consent and an insufficient response to treatment. CONCLUSION: This investigation provided the opportunity to analyze the prescriptions of a new formulation drug in routine clinical practice. It confirms the need for respecting the authorized indications and the recommendations of good use of a drug to avoid the failures of treatment and also the importance of the role of the pharmacist in recalling it to the physicians.

[Pharmacokinetic evaluation of linezolid in patients with major thermal injuries]. / Pharmacocinétique du linézolide chez des patients souffrant de brûlures sévères.

The aims of this multicentre open-label study was to evaluate the pharmacokinetics of linezolid in patients with burn injury above 20 % BSA and to compare them with healthy volunteers, matched in age, sex and weight. After a single 600 mg IV dose of linezolid, multiple blood and urine samples were taken from subjects, in order to determine linezolid concentrations, using a HPLC assay. C(max) and volume of distribution at steady state were not different between the two groups. Values describing clearance were altered in burns, leading to a reduction by half in AUC in these patients (42.5 versus 98.1 mghL(-1)). The enhancement of clearance was due to which of non renal clearance (323+/-191 versus 80.4+/-27.5 mLmin(-1)). We conclude that pharmacokinetics of linezolid are altered in burn patients, in a magnitude sufficient that linezolid concentration may be subtherapeutic in some patients and we suggest that the dosage interval may need to be decreased in this patient population.

Focused Transesophageal Echocardiography During Cardiac Arrest Resuscitation: JACC Review Topic of the Week.

Focused transthoracic echocardiography (TTE) during cardiac arrest resuscitation can enable the characterization of myocardial activity, identify potentially treatable pathologies, assist with rhythm interpretation, and provide prognostic information. However, an important limitation of TTE is the difficulty obtaining interpretable images due to external and patient-related limiting factors. Over the last decade, focused transesophageal echocardiography (TEE) has been proposed as a tool that is ideally suited to image patients in extremis-those in cardiac arrest and periarrest states. In addition to the same diagnostic and prognostic role provided by TTE images, TEE provides unique advantages including the potential to optimize the quality of chest compressions, shorten cardiopulmonary resuscitation interruptions, guide resuscitative procedures, and provides a continuous image of myocardial activity. This review discusses the rationale, supporting evidence, opportunities, and challenges, and proposes a research agenda for the use of focused TEE in cardiac arrest with the goal to improve resuscitation outcomes.

Pharmacokinetic evaluation of linezolid in patients with major thermal injuries.

AIMS: To evaluate the pharmacokinetics of linezolid following its administration in patients with major thermal injuries and in a group of healthy volunteers. METHODS: In an open-label, multicentre design with two parallel groups, a group of patients with major thermal injuries (>20% body area) and a group of age-, sex- and weight-matched healthy volunteers, subjects received a single 600 mg intravenous dose of linezolid. Serial blood and urine collections were made and the concentrations of linezolid in these samples were determined by HPLC. Non-compartmental analyses were used to describe the pharmacokinetic disposition of linezolid. RESULTS: C(max) concentrations and the volume of distribution at steady state (V(ss)) were not statistically different (P > 0.05) between the two groups of subjects. In contrast, values describing clearance [elimination rate constant (k(el)), t(1/2) and mean residence time (MRT)] were significantly different (P < 0.05) in patients with thermal injuries compared with volunteers, which lead to an approximate reduction by half in AUC(0-infinity) from 98.1 mg.h/L (volunteers) to 42.5 mg.h/L (patients). Although renal clearance was similar in the two groups (24.7 +/- 23 versus 30.6 +/- 14.3 mL/min; P = 0.156), non-renal clearance was substantially increased (323 +/- 191 versus 80.4 +/- 27.5 mL/min) in the patients with thermal injuries, though this difference did not achieve statistical significance (P = 0.063). CONCLUSIONS: The pharmacokinetics of linezolid are altered in patients with major thermal injuries, mainly as a result of increased non-renal clearance. These changes are of sufficient magnitude that linezolid concentrations may be sub-therapeutic in some patients and we suggest that the dosage interval may need to be decreased in this patient population.

[Prescribing patterns of antipsychotics in 13 French psychiatric hospitals]. / Enquête de pratiques de prescription des antipsychotiques dans 13 centres hospitaliers du réseau PIC.

INTRODUCTION: The commercial introduction of atypical antipsychotics, called second-generation antipsychotics (SGAs), a few years ago, has led to a world-wide reappraisal of the established treatment strategies for people with psychotic or bipolar disorders. They permitted improvements in the pharmacologic management of psychiatric diseases. As compared to conventional neuroleptics or first-generation antipsychotics (FGAs), they promised better efficacy especially on negative symptoms and cognitive impairments of psychiatric diseases and, at the same time, better tolerance on neurological side effects. Now, they have shown other side effects and they have a higher acquisition cost than FGAs. OBJECTIVES AND METHODS: The aim of this paper is to describe and analyse the prescribing practices of antipsychotic drugs in French psychiatric hospitals for adult inpatients and to compare them with other surveys and guidelines. In June 2004, we conducted a one-day, cross-sectional, observational and naturalistic study in 13 hospitals, members of the PIC network. RESULTS: Two thousand one hundred and ninety-two prescriptions with antipsychotic treatment were collected. One thousand one hundred and fifty-four prescriptions (52.6%) included a SGA, but the FGAs were the most prescribed (65.8%; n=2259), principally cyamemazine (24.7%). There was one antipsychotic in 50.7% of prescriptions, two antipsychotics in 42.2%, but the second neuroleptic used was a sedative (82.6%), principally cyamemazine. Multiple antipsychotics were present in 1081 prescriptions (49.3%), with an average number of 1.57 antipsychotics. A mood stabiliser, an antidepressant, an anxiolytic and a hypnotic were coprescribed in respectively 37, 30.5, 65.1 and 41.6%. There were 2.48 psychotropic drugs associated with the principal antipsychotic; in total, with correctors of side-effects of the antipsychotics, there were 3.38 drugs per prescription. The SGAs aimed more often for psychotic (F20-F29) patients (61.9% versus 43.3% with FGAs), who were males (61.4% versus 68%), younger (42.6 years versus 44.1 years; p<0.02), with higher average daily doses, more associated with other neuroleptics (p<0.0004) and less associated with anticholinergic antiparkinsonian agents (p<10(-4)) than FGAs. Compared to other surveys, these results showed that the SGAs have become the first-line treatment for psychiatric disorders. The highest average daily doses corresponded to treatments of psychotic patients and, hence, the values might largely exceed the authorized maximum doses. Furthermore, in more than half of the cases, an FGA, generally a sedative, was associated with an SGA that did not comply with the principle of monotherapy established by the national and international guidelines; that also annulled the expected benefit of the SGAs on the awakening, cognition and the neurological tolerability of the treatment. The coprescriptions of the other psychotropic drugs to neuroleptics also remained the rule in psychiatry, showing all the complexity of pharmacological psychiatric medications. Prescriptions also included treatments for side effects of antipsychotics; even on the prescriptions including the SGAs, there was the coprescription of anticholinergic antiparkinsonian drugs, the deleterious character of which one knows on cognition. This resulted in a difficulty of understanding the prescription for the patient, associated with reduced compliance and increased risks of pharmacological side effects. The heterogeneity of the situations of crisis in psychiatric hospitals could make the strict application of guidelines' recommendations difficult. Nevertheless, the educational interventions in psychopharmacology for patients and the training campaigns for psychiatrists and nurses are necessary to improve the therapeutic management of the patient and ensure him/her optimal quality of life. CONCLUSION: This kind of survey, far too rare, was very important because it showed the routine clinical settings in which these new drugs were really used. The results showed that SGAs appeared to take the place of the FGAs used in the treatment of psychoses, particularly schizophrenia, but also in the treatment of mood disorders and they reflected actual clinical practices. Other surveys must be conducted to see whether our study confirms the general trend concerning the use of these drugs and, therefore, to reassess these prescribing practices.

[Study on clozapine treatment at the Charles Perrens Hospital in Bordeaux, 15 years after its marketing]. / Enquête observationnelle de prescription de la clozapine au centre hospitalier Charles-Perrens à Bordeaux, plus de 15 ans après l'AMM en France.

INTRODUCTION: The international consensus conferences concerning schizophrenia and the authorization to market (French AMM) reserve this molecule for the treatment of resistant schizophrenia. Resistant schizophrenia, as defined by the marketing authorisation, corresponds to the absence of improvement in a patient's state despite two successive treatments with antipsychotics, or at least an atypical drug at an adequate dose for a sufficient length of time. OBJECTIVES: Our investigation compares hospital practices to the marketing authorisation and guidelines regarding resistant schizophrenia. METHODS: All clozapine prescriptions delivered by the pharmacists at the Charles Perrens Hospital were recorded during the month of February 2007. General information concerning the patient and his or her treatment were collected, based on different support teams set up in the hospital. First, the hospital administrative program was used to manage the patients. Then, the treatment establishment form, filled out by psychiatrists before the beginning of the treatment, listed all previous treatments given to the patient and indicated any inefficacy or intolerances to prior treatments. Then, a program monitored the delivery of this molecule and finally, prescriptions were recorded to describe present treatment. RESULTS: Our study consisted of 61 patients, mostly male subjects averaging 40 years of age, single, who had been under psychiatric care for about 15 years, and were, for the most part, professionally inactive. Clozapine was prescribed for schizophrenic (90%) and for bipolar patients (10%). Clozapine was also often prescribed for patients whose illness had not improved with prior treatments. The average dose was of 489 mg/day for patients considered stable, i.e., those for whom clozapine was prescribed with efficacy observed for a sufficiently long time. It was associated in 88% of all cases with another psychotropic: anxiolytic (68% of cases), normothymic (26% of cases), antidepressant (16%) and antipsychotic (42%). DISCUSSION: In practice, clozapine seems to be efficient in bipolar disorders, although the marketing authorisation does not envisage this indication. It is never prescribed first, as some recommendations indicate, even though the follow-up of certain treatments does not always seem adequate to appreciate their non-effectiveness. Seldom prescribed alone, clozapine is often associated with another antipsychotic, a practice not favoured by many experts. Our investigation thus confirms the increase in co-prescriptions, particularly in hospital, for patients who have not improved with clozapine alone, a case that is barely taken into consideration in consensus conferences. With the lack of innovative molecules, psychiatrists are prompted to associate several antipsychotics, with the risk of supporting iatrogenic medication, whereas the experts reserve the relevance of such associations because of a lack of randomised studies.
