- W2093556722 abstract "Abstract Background It is expected that the main benefit of abdominal aortic aneurysm (AAA) screening will be derived from differences in the mortality rate between elective and ruptured AAA repair. There may also be differences in elective AAA mortality rate between screened and non-screened patients, and the aim of this study was to compare mortality rates for these two groups using standard statistical analysis, Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM) and P-POSSUM scoring. Methods Patients undergoing elective AAA repair were either from a current screening programme to detect men over 65 years with AAA (screened) or were referred from other sources (non-screened). All patients were scored using the POSSUM scoring system. Mortality data were studied. Agreement between observed and expected deaths for POSSUM and P-POSSUM for screened and non-screened patients was determined. Results Some 276 elective AAA repairs were performed with an overall mortality rate of 6·9 per cent (see Table below). The mortality rate of 2·7 per cent for 111 screened patients was significantly less than that of 9·7 per cent for 165 non-screened patients (Pearson χ2 = 5·06, P = 0·02). Actual versus predicted death ratio for all elective patients was 0·93 for POSSUM and 2·38 for P-POSSUM. Conclusion Screened patients have a lower mortality rate than non-screened patients for AAA repair. POSSUM scoring provides the best prediction of death in this elective AAA group." @default.
