["VigilanSeu.r.se": A new profession?] / « VigilanSeu.r.se ¼ : un nouveau métier ?

In January 2015, in accordance with decades of scientific work based on maintaining contact, was born an innovative device for suicide prevention: VigilanS. To ensure this link, the choice was made to build a team with an equal number of nurses and psychologists, all located within the medical regulation. Nowadays, they are named "VigilanSeur": an original entity that highlights the emergence of this new profession, at the crossroads of several disciplines.

Prospective assessment of patients' knowledge and informational needs and of surgeon-to-patient information transfer before and after knee or hip arthroplasty.

BACKGROUND: Patients are playing an increasingly large role in their own management and must therefore receive clear, complete, and comprehensible information. In the field of hip and knee arthroplasty, little is known about the level of patient knowledge and effectiveness of surgeon-to-patient information transfer. We therefore designed a prospective observational study with the objective of assessing four factors: patient knowledge during management, quality of information transfer, informational needs, and factors associated with the level of knowledge. HYPOTHESIS: The level of patient knowledge changes during the management process. PATIENTS AND METHODS: A prospective single-centre study was conducted between January 2014 and March 2015 during the outpatient visits and inpatient stays of 63 patients who underwent arthroplasty of the hip (n=36) or knee (n=27). A single observer attended all patient visits and recorded the information provided by the surgeon. Each patient completed a self-questionnaire after the outpatient visit (T1), at admission (T2), and at discharge after surgery (T3). Semi-quantitative scores were used to assess knowledge and informational needs. The effectiveness of information transfer was evaluated by comparing the information provided by the surgeon to the replies made by the patients. RESULTS: The mean overall knowledge score (on a 0-42 scale) increased from 17.22±6.33 at T1 to 19.44±6.89 at T3 (P=0.0028). In contrast, knowledge about complications was better at T1 than at T3 (2.67±1.98 vs. 2.19±1.91; P<0.05). Agreement between information given by the surgeon and replies made by patients varied across items from 23% to 100%. The mean informational needs score (on a scale from 0 to 21) ranged from 3.67 to 4.83 and was higher at T3 than at T2 (4.83±3.77 vs. 3.67±4.86; P=0.03). The proportion of patients who wanted written information was higher at T3. Most patients sought information before the outpatient visit. At each step of the management process, the main areas about which the patients wanted information were the surgical procedure, the rehabilitation programme, and the prosthesis. Several socio-demographic or management-related factors influenced the level of knowledge. Thus, older age and lower educational attainment were associated with lower knowledge scores, whereas previous lower-limb orthopaedic surgery and amount of information provided by the surgeon were associated with higher knowledge scores. Knowledge scores were not associated with being employed vs. retired, gender, replacement of a hip vs. a knee, the surgeon, or being accompanied by another person. DISCUSSION: Our study is original in that we assessed changes in patient knowledge during the management process for hip or knee arthroplasty. The level of patient knowledge was fairly low and varied considerably across individuals and time points in the management process. These data highlight the importance of providing patients with information throughout their management and particularly at discharge, when the desire for information seems greatest. LEVEL OF EVIDENCE: IV, prospective observational study with no control group.

[An integrative and transdiagnostic relaxation protocol for anxious patients. Results of a pilot study]. / Protocole de relaxation intégrative et transdiagnostique pour patients anxieux. Résultats d'une étude pilote.

INTRODUCTION: The literature data show that relaxation practice is effective in reducing anxiety symptoms. Different techniques such as progressive muscular relaxation, autogenic training, applied relaxation and meditation have been evaluated independently for anxiety disorders. The question is to know whether the combination of various techniques may be of interest in the transdiagnostic treatment of anxiety disorders. AIM OF THE STUDY: The present study assessed the short-term efficacy of a 10-week integrative and transdiagnostic relaxation program for anxiety disorders in outpatients of an anxiety disorders unit. METHODS: The diagnoses were made according to the Mini-International Neuropsychiatric Interview (MINI; Sheehan et al., 1998) and completed with an assessment of anxiety and depressive symptoms using: the State Trait Anxiety Inventory (STAI-Y, -S and -T), the Penn State Worry Questionnaire (PSWQ) and the Beck Depression Inventory (BDI-II). Four techniques were integrated into the structured 10-week protocol: breathing control, muscular relaxation, meditation and mental visualization. RESULTS: Twenty-eight patients (12 men and 16 women), mean age (S.D.)=38.82 years (11.57), were included in the study. All the included patients fulfilled the DSM-IV criteria for a current diagnosis of Generalized Anxiety Disorder (n=13) or Panic Disorder (n=15) with or without agoraphobia. At the end of the 10 sessions, we found a significant reduction in mean scores (S.D.) on the STAI-T from 53.179 (6.037) to 49.821 (8.028) (P<0.02), the BDI-II 20.964 (13.167) to 15.429 (11.341) (d=0.6543) and the QIPS 55.071 (10.677) to 49.679 (11.7) (d=0.5938). The observed reduction in the STAI-S (d=0.2776) was not significant. DISCUSSION: The results of this open study showed that this program significantly decreases the level of trait anxiety, depression and worry. The integrative and transdiagnostic relaxation program could represent an accessible and effective treatment to reduce anxious and depressive symptoms in various anxiety disorders. Future research should address the development of controlled trials assessing the impact of the different dimensions of anxiety and the long-term effects of this protocol.

[Hospital-based health technology assessment in France: how to proceed to evaluate innovative medical devices?]. / Évaluation des technologies de santé en milieu hospitalier : quelle organisation pour évaluer et acquérir des dispositifs médicaux innovants ?

Innovative medical devices offer solutions to medical problems and greatly improve patients' outcomes. Like National Health Technology Assessment (HTA) agencies, hospitals face numerous requests for innovative and costly medical devices. To help local decision-makers, different approaches of hospital-based HTA (HB-HTA) have been adopted worldwide. The objective of the present paper is to explore HB-HTA models for adopting innovative medical devices in France and elsewhere. Four different models have been conceptualized: "ambassador" model, "mini-HTA" model, "HTA unit" model and "internal committee". Apparently, "HTA unit" and "internal committee" (or a mixture of both models) are the prevailing HB-HTA models in France. Nevertheless, some weaknesses of these models have been pointed out in previous works. Only few examples involving hospital pharmacists have been found abroad, except in France and in Italy. Finally, the harmonization of the assessment of innovative medical devices in France needs a better understanding of HB-HTA practices.

Evaluation of childhood exposure to di(2-ethylhexyl) phthalate from perfusion kits during long-term parenteral nutrition.

Leachability of the plasticizer di(2-ethylhexyl) phthalate (DEHP) from administration sets into intravenous parenteral emulsions containing fat was investigated. DEHP is added to polyvinyl chloride (PVC) to impart flexibility. However, DEHP is a lipid-soluble suspected carcinogen that is hepatotoxic and teratogenic in rodents, and has been shown to leach from PVC products containing lipophilic mixtures. Consequently, total parenteral nutrition (TPN) mixtures containing fat emulsions should be stored in ethylvinyl acetate (EVA) bags rather than PVC packs. However, while TPN bags are made of EVA, they contain PVC-DEHP residues and the lines used between TPN bags and venous catheters are made of PVC-DEHP. The present study quantified the amount of DEHP leached from bags and tubing that could potentially contaminate patients during home TPN. Four types of emulsions containing fat were studied. Levels of DEHP in the bag and at the outlet tubing were measured by high-performance liquid chromatography (HPLC). This was measured during simulated TPN at different times after starting perfusion, 1 day after reconstitution of solutions in the bags, and 1 week later after storage at 4 degrees C. Detectable and stable amounts of DEHP were found to leach from bags (0.2 +/- 0.008 mg to 0.7 +/- 0.02 mg) and DEHP content increased in the outlet tubing (0.8 +/- 0.09 mg to 2 +/- 0.07 mg) during simulated infusions. The same phenomenon was observed after 1 week of storage at 4 degrees C. DEHP extraction by TPN depends on the lipid content of each TPN preparation and the flow rate. These results suggest that children treated with prolonged TPN are regularly exposed to significant amounts of DEHP.

High-performance liquid chromatographic method for the determination of di(2-ethylhexyl) phthalate in total parenteral nutrition and in plasma.

A simple, rapid and sensitive reversed-phase high-performance liquid chromatographic method with UV detection was developed for the quantification of di(2-ethylhexyl) phthalate (DEHP) in parenteral nutrition admixtures containing fat emulsion and in plasma samples of children daily treated by total parenteral nutrition. The analyte and the internal standard, di-n-heptyl phthalate, were extracted twice using hexane and the organic layer separated and dried under nitrogen. The residues were reconstituted with acetonitrile and 20 microl was injected into a Waters Spherisorb C18 column, the UV detector was set at 202 nm. The mobile phase was acetonitrile-aqueous buffer (triethylamine 0.08% adjusted to pH 2.8 with 1 M phosphoric acid) mixture (88:12, v/v) and it was pumped at 1 ml/min. Average recoveries were 97% or greater. This method was successfully used to investigate the amounts of DEHP which can leach from bags and tubing into fat emulsion and which could contaminate children under long-term parenteral nutrition. On the other hand, the circulating DEHP concentrations were estimated in four children under regular long-term parenteral nutrition.
