[Preoperative cardiac-risk assessment for non-cardiac surgery: The French RICARDO survey]

Objectives: Professional practice evaluation of anaesthesiologist for high cardiac-risk patient cares in non-cardiac surgery, and assess disparities between results and recommendations.

Materials and methods: Since June to September 2011, a self-questionnaire was sent to 5000 anesthesiologist. They were considered to be representative of national anesthesiology practitioner. Different items investigated concerned: demography, preoperative cardiac-risk assessment, modalities of specialized cardiologic advice, per- and postoperative care, and finally knowledge of current recommendations.

Results: We collected 1255 questionnaire, that is to say 25% of answers. Men were 73%, 38% were employed by public hospital; 70% worked in a shared operating theatre with a general activity. With regards to preoperative assessment, 85% of anaesthetists referred high cardiac-risk patient to a cardiologist. In only 16% of answer, Lee's score appeared in anaesthesia file to assess perioperative cardiac-risk. Only 61% considered the six necessary items to optimal estimate of cardiac-risk. On the other hand, 91% measured routinely the exercise capacities by interrogation. The most frequently doing exam (49% of anaesthetist) was an electrocardiogram in elderly patient. In 96% of case, beta-blockers were given in premedication if they were usually thought. Clopidogrel was stopped by 62% of anesthetist before surgery. In this case, 38% used another medication to take over from this one. Only 7% considered revascularization in coronary patient who were effectively treated. POISE study was know by 40% of practitioner, and 18% estimated that they have changed their practice. Preoperatively, 21% organized multidisciplinary approach for high-risk patient. During surgery, 63% monitored the ST-segment. In postoperative period for cardiac-risk patient, only 11% prescribed systematically an ECG, a troponin dosage, a postoperative monitoring of ST-segment, a cardiologic advice. In case of moderate troponin elevation, they were 70% to realize at least an ECG and/or an echocardiography.

Conclusion: This study highlights some difference between current recommendation concerning assessment of cardiac-risk patient in non-cardiac surgery and daily practice of anesthetist, justifying regular update of this one.
