Insights
Medical audits may miss crucial patient data. Unreported infrainguinal bypass surgery cases had higher mortality and amputation rates than registered cases, impacting performance assessments.
Area of Science:
- Vascular Surgery
- Clinical Audit
- Health Outcomes Research
Background:
- Medical audits are essential for evaluating healthcare quality.
- Incomplete data in audits can skew performance assessments.
- Infrainguinal bypass surgery is a common vascular procedure.
Purpose of the Study:
- To determine the proportion of infrainguinal bypass operations excluded from medical audit.
- To compare patient outcomes (mortality, amputation, patency) between reported and unreported cases.
Main Methods:
- Analysis of a clinical database from six vascular surgery departments over three years.
- Inclusion of reported cases and identification of unreported cases through external sources.
- Review of mortality, amputation rates, and patency for both groups.
Main Results:
- 16% of eligible infrainguinal bypass cases were not reported.
- Unreported cases exhibited twice the mortality and amputation rates compared to reported cases.
- No significant difference in bypass patency was observed between the groups.
Conclusions:
- Exclusion of cases from medical audits can lead to underestimation of adverse outcomes.
- Incomplete audit data may impair accurate evaluation of surgical department performance.
- Ensuring comprehensive case reporting is vital for reliable quality assessment in vascular surgery.
Abstract:
The aim of the present investigation was to analyse a clinical database in order to see how many patients were not included in medical audit and to see whether the outcome of the non-registered patients differed from that of the registered patients. Two independent surgeons studied the records of all infrainguinal bypass operations performed at six vascular surgical departments over a three-year period. A total of 684 bypass operations was reported to the register, of which 636 could be reviewed. One-hundred and twenty-eight cases that had not been reported were found from other sources. The outcome variables were mortality, amputation rate and patency. Sixteen per cent of eligible cases had not been reported. Mortality and amputation rate were twice as high among the missing cases as among the reported cases. There was no difference in patency. Overall judgement of the performance of an individual department may be impaired by cases not included in the register.
