 - Julie Freyssenge : « L’accès aux soins d’urgence : une approche territoriale »  

Dans un contexte d’augmentation de la fréquentation des services d’urgence, il est essentiel de comprendre les mécanismes de recours aux soins des populations. Nous proposons une approche territoriale des soins d’urgence prenant notamment en compte les bassins démographiques et la répartition spatiale des structures.

Nous traiterons des notions d’accessibilité et de disparités spatiales à travers différents projets régionaux traitant la notion de recours aux soins d’urgence, principalement lors de la phase préhospitalière.


Clinical characteristics and outcome of elderly patients admitted in emergency department with an oxygen mismatch and type 2 myocardial infarction or myocardial injury.

Jacquin L, Mewton N, Bosne S, Mantout A, Bergerot C, Tazarourte K, Douplat M.

Background: Aging is a risk factor for type 2 myocardial infarction or myocardial injury, but few data are available on the elderly. We aimed to determine the factors associated with these pathologies and mortality in the elderly population and its age classes.

Methods: A retrospective cohort of all patients with oxygen mismatch (anemia, hypoxia, tachycardia, hypo/hypertension) for whom a troponin drawn was performed at admission in 2 emergency departments. Medical records were reviewed and classified as having type 2 myocardial infarction, acute or chronic myocardial injury, or no myocardial injury.

Improving patient self-reporting of antihypertensive adverse drug events in primary care: a stepped wedge cluster randomised trial.

Buchet-Poyau K, Occelli P, Touzet S, Langlois-Jacques C, Figon S, Dubois JP, Duclos A, Chanelière M, Colin C, Rabilloud M, Keriel-Gascou M.

Background: About 25% of patients experience adverse drug events (ADE) in primary care, but few events are reported by the patients themselves. One solution to improve the detection and management of ADEs in primary care is for patients to report them to their general practitioner. The study aimed to assess the effect of a booklet designed to improve communication and interaction between patients treated with anti-hypertensive drugs and general practitioners on the reporting of ADEs.

Methods: A cluster randomized controlled cross-sectional stepped wedge open trial (five periods of 3 months) was conducted. A cluster was a group of general practitioners working in ambulatory offices in France. Adults consulting their general practitioner to initiate, modify, or renew an antihypertensive prescription were included. A booklet including information on cardiovascular risks, antihypertensive treatments, and ADE report forms was delivered by the general practitioner to the patient in the intervention group. The primary outcome was the reporting of at least one ADE by the patient to his general practitioner during the three-month period after enrolment. Two clusters were randomised by sequence for a total of 8 to receive the intervention. An intention-to-treat analysis was conducted. A logistic mixed model with random intercept was used.

Combining proactive transcranial stimulation and cardiac biofeedback to substantially manage harmful stress effects

Schlatter S, Guillot A, Schmidt L, Mura M, Trama R, Di Rienzo F, Lilot M, Debarnot U.

Background: Previous studies have identified the dorsolateral prefrontal cortex (dlPFC) as a core region in cognitive emotional regulation. Transcranial direct current stimulations of the dlPFC (tDCS) and heart-rate variability biofeedback (BFB) are known to regulate emotional processes. However, the effect of these interventions applied either alone or concomitantly during an anticipatory stress remains unexplored.

Objective: The study investigated the effect of anodal tDCS and BFB, alone or combined, on psychophysiological stress responses and cognitive functioning.
