[The pharmaceutical record in an emergency department: Assessment of its accessibility and its impact on the level of knowledge of the patient's treatment]. / Le dossier pharmaceutique dans un service d'accueil des urgences : évaluation de son accessibilité et de son impact sur le niveau de connaissance du traitement du patient.

Knowledge of the home medication list may impact therapeutic decisions made in the emergency department (ED). In France, the pharmaceutical record (PR) is a shared professional tool arising from the pharmacists lists of all drugs dispensed during the last 4 months. This PR is included in a microchip equipping a "Vitale" card detained by each beneficiary of health insurance benefits. Since 2011, the law authorises experimentally the consultation of the PR by some hospital doctors such as those working in emergency medicine. The purpose of this work is to assess the accessibility to this PR and to verify the hypothesis that its consultation increases the level of information concerning the treatment of patients admitted in an ED. A prospective, single-center, observational study was conducted during a 15-day period on all patients arriving at the Agen hospital emergency department. Of the 1046 patients enrolled in the study, 828 (79 %) presented a "Vitale" card in which a PR furnished with data was found in 45 % of the cases. The only paper source of information available was provided by the PR (25 %), a medical letter (6 %) or a prescription (3 %). A dual reconciliation between 2 of these sources was possible at a rate of about 4 % each whereas only 3 % of patients showed up with the 3 sources of available information. The consultation of PR by the ED staff is significantly possible. It improves quantitatively the level of information and thus optimizes medication assessment, the initial and critical step of the medical management of patients.
