RESUMEN
Older patients represent an increasing population in emergency department (ED) with underlying diseases and longer ED length of stay, which are potential risk factors of pressure ulcers (PUs). The aim of the study was to determine the prevalence and incidence rates of PUs in an Emergency Department and to analyse variables related to PUs occurrence. The study was carried out in the Emergency Department of Bordeaux (France), and included 602 patients from 1 to 15 June 2010. All the potential body sites of pressure were examined at admission and discharge for all the patients by trained nurses. Comorbidity score, list of treatment, length of stay (hours), PUs (including stage I) and C-reactive protein (CRP) level were systematically recorded. A total of 47 (7·8%) patients had prevalent PUs at admission and 74 (12·3%) at discharge. The cumulative incidence was 4·9% and the incidence density was 5·4 per 1000 patients per hour. In multivariate analysis, higher comorbidities (OR 1·3; P = 0·014) and CRP levels (OR 1·005; P = 0·017) were both independent risk factors for developing PU. In conclusion, these data show that even a very short stay to the ED is sufficient to induce PUs especially stage I.

OBJECTIVE: To assess if use of psychotropic drugs is associated with an increased risk of admission for heat-related pathologies during a heat wave period. METHOD: We conducted a matched case-control study. Cases were defined as subjects admitted to an emergency department for heat-related pathology (hyperthermia or heat stroke) over the August 2003 heat wave. Controls were defined as subjects living in the same area but not hospitalised over the same period and who had at least one prescription form submitted for refunding by the social security insurance in July 2003. Multivariate analyses were used to identify psychotropic drugs independently associated with hospital referral during the heat wave period. RESULTS: Out of the 1405 patients admitted to the emergency department, 56 (4%) presented with heat-related pathology. The mean age of cases was 83 years. Multivariate analyses showed that cases were more likely than controls to be treated with anticholinergic drugs (OR 6.0, 95% CI 1.8-19.6), antipsychotics (OR 4.6, 95% CI 1.9-11.2) or anxiolytics (OR 2.4, 95% CI 1.3-4.4). CONCLUSION: In special risk situations such as heat waves, the risk/benefit ratio of psychotropic drugs which could interfere with body temperature regulation has to be carefully assessed, particularly in the elderly.
