- Aim: To investigate the degree to which specialisation or case-load of the surgeon is associated with the number of lymph nodes isolated from pathology specimens after right-sided hemicolectomy. Method: Data from 6 hospitals with well-defined catchment areas included in the Uppsala/Orebro Regional Oncology Centre Colon Cancer Register 1997-2006 were used to assess 821 patients undergoing right-sided hemicolectomy for stages I Ill colon cancer. Factors influencing the lymph node yield were evaluated. Results: A surgeon with colorectal accreditation and a university pathology department were both associated with a significantly higher proportion of patients having 12 or more lymph nodes isolated from surgical specimens after right-sided hemicolectomy in both unadjusted and multivariate analyses. Emergency surgery did not affect the lymph node yield. Conclusion: The degree of specialisation of the surgeon influences the number of lymph nodes isolated from specimens obtained during routine right-sided colon cancer surgery.

- BACKGROUND: Population-based quality registers have become an important tool in quality assessment during the past decade. For registers to be reliable, however, data must be checked carefully for validity.METHODS: The present study describes the validity of surgical complications registered in a national register run by the National Board of Health and Welfare (NBH), a register run by Regional Oncological Centres (ROC) and, for comparison, a local quality assurance system at Uppsala University Hospital (UUH). A specialized, independent surgeon checked 10 per cent of patient records against datasheets from the registers.RESULTS: The local quality assurance system at UUH showed the best validity for surgical complications. Data for complications of colonic cancer surgery were more valid than those for rectal cancer surgery. Registration of serious complications was more valid than that of wound infections. The calculated proportion of missed surgical complications was 0.69, 0.64, 0.40, 0.22 and 0.07 for rectal and colonic cancer in the NBH register, rectal and colonic cancer in the ROC register, and the UUH register respectively. Corresponding figures for reoperation were 0.45, 0.48, 0.04, 0.09 and 0.21.CONCLUSION: Local interest and routine use of data for quality assurance are crucial factors for valid registers. Careful monitoring of validity is necessary for use of registry data in structured systems for improvement of surgical results.

- AIMS: The aim of this study was to describe variability in compliance to clinical guidelines in colorectal cancer surgery related to hospital structure.METHODS: All patients registered in the databases of the Regional Oncologic Centre, operated upon electively for colon cancer between the start of the register in 1997 until 2000 (n=1771) and for rectal cancer between the start of the register in 1995 until 2000 (n=1841) were selected for analysis.RESULTS: There was no difference in 5-year survival rate between colon and rectal cancer (mean follow-up 2.6 and 3.0 years, respectively; p=0.22). There was a significant difference in frequency of preoperative liver scan depending on hospital category with an increase in colon cancer from 39 to 46% (p=0.02) and in rectal cancer from 42 to 64% (p<0.001). For colon cancer there was no difference, according to hospital category, in quotient sigmoid and high anterior resection to left-sided resection. Furthermore, high anterior resection was more common at university and general district hospitals (8%) compared with district hospitals (4%) (p=0.01). Sphincter-saving surgery was more common at university hospitals and district general hospitals than at district hospitals (low anterior/abdomino-perineal resection quotients 2.3, 2.4 and 1.6, respectively; p<0.001).CONCLUSIONS: Population-based audit forms an appropriate and valuable basis for quality assurance projects. In addition to describing compliance to guidelines and pointing to process steps that can be improved, such investigations may also indicate changes due to scientific development. Linked to case-costing data, such results may form an important basis for decisions about modifications in health care.
