[How to increase the involvement of casualty patients in their treatments: efficacy of some informative posters].
OBJECTIVE
To determine whether posters/leaflets increase doctors' information on the allergies and on the medication their patients are taking and patients' understanding of their treatment.


METHODS
First stage: multi-centre transversal descriptive study. Second stage: intervention with control and without randomisation.


METHODS
Primary care medical emergency services (MES).


METHODS
MES patients under prescribed drug treatment.


METHODS
Use of posters/leaflets.


METHODS
1) Proportion of patients for whom the doctor was ignorant of allergies to drugs or of accompanying medication. 2) Proportion of prescriptions in which patients understood the dosage of the medication prescribed.


METHODS
ad hoc questionnaire to patients.


METHODS
chi2 test (category variables). In some cases, the Breslow-Day and Tarone tests were conducted.


RESULTS
Total patients included, 1233; 1766 prescriptions analysed; 53.4% women. Mean age: 29+/-18 years old. 1) Doctor's understanding of accompanying medication: at the second stage, drop of 25.5% (95% CI, 33.5-17.5) for intervention group versus drop of 12.5% (95% CI, 19.8-5.2) for control group, in the number of patients for whom the doctor did not know the medication (P=.024). 2) Patient's understanding of dosage: at the second stage, increase of 16.8% (95% CI, 9.8-23.8) for intervention group, versus a decrease of 1% in control group, in the medicines whose dosage the patient was aware of (P<.001).


CONCLUSIONS
The dissemination of posters/leaflets was effective in increasing patients' knowledge of their medication's dosage and doctors' understanding of questions affecting prescription.
