Usefulness of POSSUM physiological score for the estimation of morbidity and mortality risk after elective XXXX repair in Japan.

@entity1 @entity8 @entity1028 @entity190
BACKGROUND: The Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM), which consists of a physiological score (PS) and an operative severity score, is useful in determining the risk profile for @entity1 with @entity1028 in Western countries, but no information is available on the use of this method in Japan. METHODS AND RESULTS: A retrospective cohort study involving 225 @entity1 was performed, and the prognostic factors for morbidity and in-hospital mortality including POSSUM were investigated. The morbidity rate was 26%. On univariate analysis age, @entity8 , hemoglobin, albumin, operation time, @entity190 and PS were significantly different. On multivariate analysis PS was significantly different. Using receiver operating characteristic (ROC) analysis, PS had an area under the curve (AUC) of 0.712 and the best cut-off point was 18. The in-hospital mortality rate was 2.2%. On univariate analysis @entity8 , albumin and PS were significantly different, and on multivariate analysis PS was significantly different. On ROC analysis PS had an AUC of 0.921 and the best cut-off point was 22. CONCLUSIONS: PS was the only independent risk factor for morbidity and in-hospital mortality. Further studies may be required to develop a risk-scoring system.
