[Physical restraint of the adult patient with uncontrollable agitation]. / Contention physique du patient adulte présentant une agitation incontrôlable.

In the context of psychiatric emergencies, it is important to distinguish between so-called controllable agitation and uncontrollable agitation. In this context, physical restraint of the adult patient is sometimes necessary, but remain an exceptional measure. Restraints must be applied rapidly and in a protocolised manner. It should be used sparingly in the elderly patient. Physical restraint is a medical prescription that must be accompanied by chemical restraint.

[Medico-legal framework for emergency care of a patient with psychiatric conditions]. / Cadre médico-légal des soins en urgence d'un patient à présentation psychiatrique.

The care and referral of patients with psychiatric conditions is a perilous process. It combines the need for care with respect for individual freedom. Knowledge of the different legal frameworks is thus necessary for psychiatric care at the request of a third party, care without request of a third party within the framework of a procedure for imminent danger, and finally for the injunction of psychiatric care on the decision of a State representative. These are necessary prerequisites for practising in an emergency structure.

Comparative value of Doppler echocardiography and B-type natriuretic peptide assay in the etiologic diagnosis of acute dyspnea.

OBJECTIVES: We compared the accuracy of B-type natriuretic peptide (BNP) assay with Doppler echocardiography for the diagnosis of decompensated congestive left-heart failure (CHF) in patients with acute dyspnea. BACKGROUND: Both BNP and Doppler echocardiography have been described as relevant diagnostic tests for heart failure. METHODS: One hundred sixty-three consecutive patients with severe dyspnea underwent BNP assay and Doppler echocardiogram on admission. The accuracy of the two methods for etiologic diagnosis was compared on the basis of the final diagnoses established by physicians who were blinded to the BNP and Doppler findings. RESULTS: The final etiologic diagnosis was CHF in 115 patients. Twenty-four patients (15%) were misdiagnosed at admission. The BNP concentration was 1,022 +/- 742 pg/ml in the CHF subgroup and 187 +/- 158 pg/ml in the other patients (p < 0.01). A BNP cutoff of 300 pg/ml correctly classified 88% of the patients (odds ratio [OR] 85 [19 to 376], p < 0.0001), but a high negative predictive value (90%) was only obtained when the cutoff was lowered to 80 pg/ml. The etiologic value of BNP was low in patients with values between 80 and 300 pg/ml (OR 1.85 [0.4 to 7.8], p = 0.4) and also in patients who were studied very soon after onset of acute dyspnea. Among the 138 patients with assessable Doppler findings, a "restrictive" mitral inflow pattern had a diagnostic accuracy for CHF of 91% (OR 482 [77 to 3,011], p < 0.0001), regardless of the BNP level. CONCLUSIONS: Bedside BNP measurement and Doppler echocardiography are both useful for establishing the cause of acute dyspnea. However, Doppler analysis of the mitral inflow pattern was more accurate, particularly in patients with intermediate BNP levels or "flash" pulmonary edema.

Personal decision-making criteria related to seasonal and pandemic A(H1N1) influenza-vaccination acceptance among French healthcare workers.

BACKGROUND: Influenza-vaccination rates among healthcare workers (HCW) remain low worldwide, even during the 2009 A(H1N1) pandemic. In France, this vaccination is free but administered on a voluntary basis. We investigated the factors influencing HCW influenza vaccination. METHODS: In June-July 2010, HCW from wards of five French hospitals completed a cross-sectional survey. A multifaceted campaign aimed at improving vaccination coverage in this hospital group was conducted before and during the 2009 pandemic. Using an anonymous self-administered questionnaire, we assessed the relationships between seasonal (SIV) and pandemic (PIV) influenza vaccinations, and sociodemographic and professional characteristics, previous and current vaccination statuses, and 33 statements investigating 10 sociocognitive domains. The sociocognitive domains describing HCWs' SIV and PIV profiles were analyzed using the classification-and-regression-tree method. RESULTS: Of the HCWs responding to our survey, 1480 were paramedical and 401 were medical with 2009 vaccination rates of 30% and 58% for SIV and 21% and 71% for PIV, respectively (p<0.0001 for both SIV and PIV vaccinations). Older age, prior SIV, working in emergency departments or intensive care units, being a medical HCW and the hospital they worked in were associated with both vaccinations; while work shift was associated only with PIV. Sociocognitive domains associated with both vaccinations were self-perception of benefits and health motivation for all HCW. For medical HCW, being a role model was an additional domain associated with SIV and PIV. CONCLUSIONS: Both vaccination rates remained low. Vaccination mainly depended on self-determined factors and for medical HCW, being a role model.
