[Clinical practice guidelines, what do the internists think?].

OBJECTIVE: Study the opinion and expectations of the internists in the public hospitals in the Brittany area regarding Clinical Practice Guidelines (CPG). METHODS: Cross-sectional survey using an anonymous, self-administered questionnaire, with closed questions concerning age, gender and status (internist in general medicine (IGM) or internist specialization student [ISS]), years and context of practice, the personal opinion of the residents regarding the CPG, the nature of those that they apply, their opinion on the interest and foreseeable impact of efforts in improvements and elaboration and prompting to use the guidelines. Descriptive analysis and statistics (chi 2) were made of the associations between the replies concerning the CPG and the characteristics of the internists. RESULTS: Among the 106 questionnaires analysed (reply rate: 50%), 96 internists (90%) felt that the advantages of the CPG were greater than their inconveniences and 66 (62%) claimed they applied the CPG in routine practice. Eighty-five (80%) considered efforts to improve the elaboration of CPG were of interest and 97 (91%) replied likewise regarding their accompanied diffusion. Guidelines concerning both diagnosis and treatment of common diseases, developed on national level and adapted locally, presented in summarized pocket-sized form and transmitted directly by the physicians of the department would have the best chance of being used. CONCLUSION: Any program aimed at developing the use of CPG in hospital departments should take into account the enthusiasm of the internists, but also the implication of senior physicians required in their specific accompanied diffusion.

Aortic Carpentier-Edwards supraannular porcine bioprosthesis: a 12-year experience.

BACKGROUND: After 35 years of cardiac valve replacement, the ideal substitute remains to be found. Homografts are considered best but, due to their scarcity, cannot meet the need of valve replacement. Artificial valves (mechanical or biological) remain the most commonly used but controversy is still present as to the better choice. We tested the Carpentier-Edwards bioprosthesis for its efficacy in valve replacement operations. METHODS: From 1983 to 1995, 1,108 consecutive patients had an isolated aortic valve replacement with a porcine Carpentier-Edwards bioprosthesis, model 2650 supraannular valve. Mean age was 73.8+/-8.3 years. Aortic stenosis was the most common lesion (1,049 patients, 94.7%). The follow-up of 980 operative survivors was 96% complete and represented a total of 4,735 patient-years (maximum, 13.8 years; mean, 4 years and 10 months). RESULTS: Actuarial survival including operative mortality (128 patients, 11.6%) was 43.6%+/-2.3% at 10 years and 27.3%+/-3.3% at 12 years and, at that time, was not statistically different from those of the normal French population matched for age and sex. Structural deterioration of the valve was observed in 27 patients, an actuarial freedom of 94.2%+/-1.5% at 10 years and 83.8%+/-4.5% at 12 years. Hazard function revealed a stable and low risk of structural deterioration until 10 years and significantly increased risk after that. Young age was found to be an increasing risk factor of deterioration. Reoperation for valve-related complications was necessary in 30 patients, an actuarial freedom of 94.5%+/-1.4% at 10 years. CONCLUSIONS: The Carpentier-Edwards porcine supraannular valve affords a good durability up to 10 years, with a low rate of reoperation. The risk of structural deterioration decreases with older age. It is our valve of choice in elderly patients.
