The nation-wide register of hospital discharges in Norway includes ICD-9 and national procedure codes. Hospitals were asked to check five surgical procedures listed in the register against the primary data sources. 649 discharges were controlled. The response rate was 68%. The results indicate that the quality of the data in the register varies for the different procedures. For procedures with high volume (resection of rectum), the error in the register is 3%. This is the same as reported from other Nordic countries. The proportion of errors in the register was high in hospitals with only one registered procedure code. The quality of data can to some extent be checked on the basis of DRG coding (DRG group 468/477). Quality control of register data is required when the number in DRG 468/477 is high in the nation-wide register or when the number of specific procedures in hospitals is low.
To determine whether the improved outcome of a surgical procedure in high volume hospitals is specific to the volume of the same procedure.
Analysis of secondary data in Ontario, Canada.
Patients having an oesophagectomy, colorectal resection for cancer, pancreaticoduodenectomy, major lung resection for cancer, or repair of an unruptured abdominal aortic aneurysm between 1994 and 1999.
Odds ratio for death within 30 days of surgery in relation to the hospital volume of the same surgical procedure and the hospital volume of the other four procedures. Estimates were adjusted for age, sex, and comorbidity and accounted for hospital level clustering.
With the exception of colorectal resection, 30 day mortality seemed to be inversely related not only to the hospital volume of the same procedure but also to the hospital volume of most of the other procedures. In some cases the effect of the volume of a different procedure was stronger than the effect of the volume of the same procedure. For example, the association of mortality from pancreaticoduodenectomy with hospital volume of lung resection (odds ratio for death in hospitals with a high volume of lung resection compared with low volume 0.36, 95% confidence interval 0.23 to 0.57) was much stronger than the association of mortality from pancreaticoduodenectomy with hospital volume of pancreaticoduodenectomy (0.76, 0.44 to 1.32).
The inverse association between high volume of procedure and risk of operative death is not specific to the volume of the procedure being studied.

Surgery makes many demands of both hospitals and patients. For the hospital, there are many procedural aspects: admission, health assessment, and patient education; the actual operation; and the post-surgical recovery period, a time when patients are susceptible to complications and nosocomial infections. For the patient, surgery means physical pain and emotional anxiety. A pre-operative assessment clinic (POAC), however, can assist both hospital and patients by streamlining their admission, assessment, and education, by decreasing the time they spend in the hospital recovering from surgery, and by easing their anxiety. In this article, the authors describe a study of a POAC at a Canadian hospital.
The paper discusses development issues of surgical procedures coding systems for use at the national and international levels within the health information systems. The work was carried out using the Russian and foreign experiences, including international standard ISO/FDIS 1828:2012. The development system structure contains basic categories of medical entities (axes): surgical deed and surgical subdeed, objects, site and interventional equipment. Abdominal surgeries (528 procedures) were entered in the coding system database and structured according defined categories.
The study evaluates the changes in socio-economic equity in the use of general hospital care in Finland from the late 1980s to the mid 1990s. In the early 1990s the Finnish economy plunged into a deep recession which slashed over 10% of GDP and resulted in a 12% decrease in national health expenditure. At the same time, the administration and financing of specialised health services were reformed. The impact on general hospital care was controversial: budgets were reduced but better productivity increased the supply of many services. According to the study, data, based on individual linkage of nationwide hospital registers to disposable family income data in population censuses, overall acute general hospital admission rates among Finns aged 25-74 increased by over 10% from 1988 to 1996. For some surgical procedures, such as cataract, coronary revascularisation and some orthopaedic operations, rates more than doubled. In both years, lower-income groups generally used hospital care more than the better-off. However, there was a slight shift towards a pro-rich distribution, mainly due to a larger increase in surgical care among the high-income groups. In 1988 the lowest income quintile used 8% and in 1996 15% fewer operations than the highest. For individual procedures and surgical diagnostic categories, the general trends of increasing disparities were similar. Despite cuts in expenditures in the early 1990s, the Finnish general hospital system based on public funding and provision managed to increase the supply of services. However, this increase coincided with widening socio-economic discrepancies in the use of surgical services. The paper proposes that these increasing inequities were due to certain features of the Finnish health care system which create social discrepancies in access to hospital care. These include the high profile of the private sector in specialised ambulatory care and in the supply of some elective procedures, and semi-private public hospital services requiring supplementary payments from patients.
