Quality of care in adult heart surgery: proposal for a self-assessment approach based on a French multicenter study

Eur J Cardiothorac Surg. 1995;9(8):433-9; discussion 439-40. doi: 10.1016/s1010-7940(05)80078-8.

Abstract

A prospective study was carried out from January to April 1993 in 42 centers to assess the quality of care in adult heart surgery in France. One hundred eight parameters were collected (i.e., risk factors, surgery, postoperative course) for 7181 patients. Eight simple, objective factors were selected using a multivariate analysis. Point weighting was assigned to each factor. A simple cumulative score was thereby established to classify patients within four incremental risk groups (respective distribution of patients and mortality were 38.6%, 26.5%, 21.3%, 13.5% and 2%, 3.9%, 6.1%, 21.4%). This score was highly predictive for mortality and severe morbidity. Objectivity and independence of the observer, coupled with a reliable score, are needed for meaningful assessment of the quality of care. Administrative supervision and/or comparison of raw center results therefore remain controversial. A national data base was developed as a part of this study, that includes anonymous information from two-thirds of all cardiac surgery cases. Nation-wide results for France allow each center freely to assess its results. This self-assessment approach is, in our view, the most accurate way of quality of care assessment. A pan-European system using a similar approach should be developed.
