AIM: To improve the communication during shift handover in an emergency department. METHODS: We observed the handover process and analysed the discourse between physicians at shift change first, and then we created two cognitive tools and tested their clinical impact on the field. We used different measures to evaluate this impact on the health care process including the frequency and type of information content communicated between physicians, duration of the handoff, physician self-evaluation of the quality of the handoff and a posthandover study of patient handling. RESULTS: Our results showed that the patient's medical history, significant test results, recommendations (treatment plan) and patient follow-up were communicated to a greater extent when the tools are used. We also found that physicians spent more time at the bedside and less time consulting medical records using these tools. CONCLUSION: The present study showed how in-depth observations and analyses of real work processes can be used to better support the quality of patient care. [less ▲]

Les services d’urgence sont régulièrement confrontés au problème d’encombrement à l’admission par une demande qui dépasse l’offre de soins. Il est essentiel de réguler le flux d’entrée par la mise en place d’un dispositif de tri. Ce mécanisme s’affine depuis une quinzaine d’années. Nous proposons un algorithme de tri (ELISA ou Echelle Liégeoise de l’Indice de Sévérité à l’Admission) qui vise à définir l’état d’urgence selon 5 niveaux depuis la catégorie U1 (urgence absolue) à U5 (urgence relative). Ces niveaux sont associés à un délai de contact médical (immédiat à 120 minutes) et à un trajet de soin correspondant (salle de déchoquage, secteur B ou brancard, secteur A ou ambulatoire, salle d’attente) réunissant ainsi des impératifs de temps et de lieu de prise en charge optimaux. Notre algorithme de tri montre une excellente fiabilité par la comparaison du niveau initial de la catégorisation au devenir du patient (soins intensifs, hospitalisation, et sortie du service).

OBJECTIVES: Due to the recent interest in hands-only protocols for dispatcher-assisted cardiopulmonary resuscitation (CPR) and the lack of any validated algorithms in French, our primary objective was to evaluate a new French-language protocol in terms of its efficacy to help previously untrained volunteers in performing basic life support efforts of appropriate quality, and secondarily to investigate its potential utility in subjects with previous training. METHODS: Untrained volunteers were recruited among adults in a public movie centre and previously trained volunteers among undergraduate nursing students. Participants were randomly assigned to 'phone CPR' versus 'no phone CPR' by drawing sets of envelopes. Primary outcome measures were the results of the Cardiff evaluation test; the secondary measures were global scoring of a complete 5min period of CPR, in a manikin model of cardiac arrest. RESULTS: Out of 146 volunteers assessed for eligibility, 36 previously untrained candidates declined participation. 110 participants, distributed into four groups, completed the study: the previously untrained non-guided group (group A, n=30), the previously untrained guided group (group B, n=30), the previously trained non-guided group (group C, n=25) and the previously trained guided group (group D, n=25). Results of the Cardiff test and global evaluation of CPR performance revealed a significant improvement in group B as compared with group A, approaching the level of the group C. Previously trained guided bystanders had the best CPR scores, notably because of an improvement in the quality of airway management. CONCLUSION: When used by dispatchers, this new French-language algorithm offers the opportunity to help previously untrained bystanders initiate CPR. The same protocol may serve to guide volunteers with prior basic life support training to reach their best CPR performance. [less ▲]

The cardiac muscle activation or driver function, is a major determinant of cardiovascular dynamics, and is often approximated by the ratio of the left ventricle pressure to the left ventricle volume. In an intensive care unit, the left ventricle pressure is usually never measured, and the left ventricle volume is only measured occasionally by echocardiography, so is not available real-time. This paper develops a method for identifying the driver function based on correlates with geometrical features in the aortic pressure waveform. The method is included in an overall cardiovascular modelling approach, and is clinically validated on a porcine model of pulmonary embolism. For validation a comparison is done between the optimized parameters for a baseline model, which uses the direct measurements of the left ventricle pressure and volume, and the optimized parameters from the approximated driver function. The parameters do not significantly change between the two approaches thus showing that the patient specific approach to identifying the driver function is valid, and has potential clinically.
