Descriptive study comparing routine hospital administrative data with the Vascular Society of Great Britain and Ireland's National Vascular Database.

OBJECTIVE: To compare patient volume and outcomes in vascular surgery between an administrative data set (Hospital Episode Statistics) and a clinical database (National Vascular Database). DESIGN: Descriptive study. METHODS: Volume of cases determined by age, sex, year and procedure and in-hospital mortality by procedure for both datasets for patients undergoing either repair of abdominal aortic aneurysm, carotid endarterectomy or infrainguinal bypass over a three year period between 1st April 2001 and 31st March 2004. RESULTS: There were 32,242 admissions with a mention of the three selected vascular procedures within the administrative data set compared to 8462 within the clinical database. For NHS trusts common to both datasets, there were twice as many procedures (16,923) recorded within the administrative dataset compared to the clinical database. Patient characteristics were similar across both databases. Further analysis limiting the administrative data to records attributed to consultants known to contribute to the clinical database showed much closer agreement with only 11% more repairs of abdominal aortic aneurysm recorded within the administrative dataset compared to the National Vascular Database. CONCLUSIONS: There are significant differences in total numbers between HES and the NVD. If the National Vascular Database is to become a credible source of information on activity and outcomes for vascular surgery, there is a clear need to increase the number of contributing surgeons and to increase the completeness of data submitted. Further analysis at individual record level is needed to identify other reasons for discrepancies which could help to enhance data quality, both within Hospital Episode Statistics and within the National Vascular Database.

Sub-specialization in general surgery: the problem of providing a safe emergency general surgical service.

BACKGROUND: The increasing subspecialization of general surgeons in their elective work may result in deskilling and create problems in providing expert care for emergency cases. To evaluate the size of the problem this study determined how often complex emergency surgical cases are treated by general surgeons working outside their own elective subspecialty. METHOD: In a district general hospital in the south of the UK serving a population of 550 000 where there is almost complete subspecialization within general surgery, 1554 patients having emergency general surgical operations were studied in a one-year review. The time an operation occurred, the seniority of the operating surgeon, the subspecialty interest of the consultant responsible for the case compared with the specialist nature of the operation was determined. RESULTS: Of 1554 patients having emergency general surgical operations, 23% (352/1554) were of a high category of complexity. Ninety were vascular procedures and were dealt with by specialist vascular surgeons on a separate rota. Of the remaining 262 operations, 78 (30%) did not match the subspecialty of the consultant surgeon responsible for their care; 56 (72%) of these occurred out of hours of which 14 (18%) had a consultant surgeon present and scrubbed in the theatre; one per month of the study. Seventy-three percent (57/78) of these were complex colorectal operations. CONCLUSION: The mismatch between the subspecialist elective interests of the consultant general surgeon and out of hours specialist major surgery needing consultant involvement occurred infrequently, and was mainly due to major lower gastrointestinal cases managed by upper gastrointestinal and breast surgeons. This has important implications for the future training of general surgeons and the provision of an emergency nonvascular general surgical service.

The post-operative mortality of ruptured abdominal aortic aneurysm repair.

INTRODUCTION: Late peri-operative death after ruptured abdominal aortic aneurysm (RAAA) repair is usually due to multiple-organ failure. The aim of this study was to identify any factors that are associated with mortality in this group of patients. METHODS: A retrospective case-note review of a single decade's operative experience of RAAA repair in a single centre. Only those patients with confirmed rupture at laparotomy were included. Sixty-three pre- intra- and post-operative variables were recorded where possible for each patient who survived surgery and the initial 24-hours post-operatively. Multi-variate analysis was performed using stepwise logistic regression. The P-POSSUM, RAAA-POSSUM, RAAA-POSSUM (physiology only), V-POSSUM, and V-POSSUM (physiology only) models were all compared to determine how each performed in these patients. RESULTS: Two hundred and twenty-three cases of confirmed RAAA were identified, of whom 139 survived the operation and initial 24-hours post-operatively. In-hospital mortality in this group of patients was 32.4%. Variables significantly associated with mortality after multi-variate analysis, were low intra-operative systolic blood pressure, the presence of a consultant anaesthetist at the initial operation and the development of cardiac, renal or gastro-intestinal complications. All POSSUM models except the V-POSSUM and P-POSSUM (physiology only) models demonstrated no significant lack of fit in this dataset. DISCUSSION: Factors associated with delayed peri-operative death after RAAA are not the same as those previously found to be associated with overall peri-operative mortality after RAAA repair.

Comparison of POSSUM scoring and the Hardman Index in selection of patients for repair of ruptured abdominal aortic aneurysm.

BACKGROUND: The aim was to assess to what extent the POSSUM (Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity) and Hardman scoring systems were predictive of outcome after surgery for ruptured abdominal aortic aneurysm (RAAA). METHODS: From January 1990 to December 2001, 232 patients presented with RAAA. Forty-one were treated conservatively and all died; the remainder had emergency surgery. The case notes of all but three of these patients were reviewed retrospectively. POSSUM and Hardman scores were calculated and related to mortality. RESULTS: The mortality rate after emergency repair was 54 per cent (104 of 191). The physiology-only POSSUM score specific for RAAA and the Hardman Index score were both significantly associated with increased mortality after operation (P < 0.001). Most non-operated patients were in the highest risk bands. CONCLUSION: Both POSSUM and Hardman scoring systems predicted outcome after emergency surgery for RAAA. The Hardman Index was simpler to calculate, but POSSUM identified a higher number of patients at risk. Risk scoring may help identify patients with RAAA for whom surgery is futile.
