[Risk score and postoperative complications in pediatric surgery].

We have developed a risk score meeting the special demands of pediatric surgery. It conveys an objective impression of the patients' preoperative condition and enables us to predict their individual intra- and postoperative behavior. This study compiles the course of 1425 operations carried out between 1986 and 1990. They were divided into low, intermediate and high risk. In addition, the patients were classified into six different age groups. We demonstrate that the number of points assigned by our risk score is highly correlated with the rate of complications that occurred, that accompanying malformations and diseases are correctly picked up and weighed by the score as far as their importance for the postoperative course is concerned, that the score is suitable for ascertaining which patients have a high probability of developing complications: the specificity is close to 100% for more than 12 points on the score, and the proportion of correctly predicted lethal courses (sensitivity) is also close to 100%. The significance of the risk score lies first in the possibility of giving patients exact data on the intra- and postoperative risk, and secondly in the provision of an objective measure of quality control--which is legally prescribed in Germany--and comparison with other hospitals. Third, the risk score gives clear starting points for research aiming at improvement in the field of surgery in sick children, and lastly it forms the basis for reliable preoperative recognition of high-risk as needed patients for modern payment methodology of the per-cose costs and thus makes it possible to charge accordingly.
