[Guidelines on difficult intubation in anesthesia: evaluation of 2 information diffusion methods].
BACKGROUND
In 1996, experts from the Société Française d'Anesthésie et de Réanimation published guidelines about difficult intubation. We aimed to assess the effectiveness of two diffusion methods of these guidelines, media versus direct mailing plus media diffusion, and the relation between reading of the guidelines and practice behavior and training willingness.


METHODS
Data were collected in two different samples of 300 anesthetists from three regions for pre and post-intervention surveys (E1 and E2 samples). Half of the anesthetists from E2, randomly chosen, received a direct mailing of the guidelines (E2a sample). The remaining constituted the E2b sample. Three assessment criteria were used, two concerning practice behavior and one training willingness. Relationship between these criteria and diffusion methods and reading was tested using logistic regression.


RESULTS
The response rates were respectively 91%, 80% and 78% in the E1, E2a and E2b samples. The socio-professional features were not statistically different between the three samples. There was no relationship between the criteria and the diffusion methods. The direct mailing did not increase the reading rate (81% and 82% respectively in the E2a and E2b samples). The rate of anesthetists who routinely screened for predictive signs of difficult intubation (one of the practice criteria) was higher in E2a than in E2b (28% and 12% respectively). In the multivariate analysis, the difference only appeared among the sub-group of anesthetists who did not receive the direct mailing. The private practice was associated with a lower rate of routine screening.


CONCLUSIONS
No impact of the diffusion methods on practice behavior and training willingness was found. Reading was inconstantly associated with practice behavior.
