Completeness and correctness of cholecystectomy data in a national register—gallriks

Abstract

Background and Aims: to validate the swedish register for gallstone surgery and endoscopic retrograde Cholangiopancreatography (gallriks) concerning completeness and correctness of entered data for cholecystectomies and evaluating the effect of repeated audits. it is crucial for any register to obtain a high accuracy in order to be a credible and reliable source for quality evaluation, research, and development.Materials and Methods: Completeness was determined by cross-matching the register with the swedish national patient register. Completeness and overall correctness were assessed by comparing registered data to medical records. Correctness for rare occasions, such as bile duct injuries, was evaluated by comparing with claims sent to the swedish patient insurance.Results: of 64,538 cholecystectomies, 82.9% of the operations were registered in gallriks and the coverage increased over time. by random sample, 94,919 sets of data were available for comparison at the first and second audit and the entries were found to be correct in 97.2% and 98.2% cases, respectively. a 100% correctness for bile duct injuries (n = 40) was seen when the index-operation was registered in gallriks.Conclusion: gallriks demonstrates high completeness, high correctness of entered data, and no indications of failure to report serious adverse events. repeated audits increased the quality of registered data. gallriks may be used for clinical evaluation on local and national level and the database enables scientific studies to be performed.

Quality-of-life after bile duct injury: intraoperative detection is crucial. A national case-control study

“…19 In contrast to previous publications from tertiary referral centres, we report on an unselected population-based cohort of BDIs compared to a matched control group. This study presents a median follow-up interval of 4.3 years after cholecystectomy.…”

“…The register has been validated and 100% of BDIs were included in the register when compared with Löf, the national patient insurance register. 19 In Sweden approximately 12,000 cholecystectomies are performed annually and registered in GallRiks. 19,20 One third of cholecystectomies are performed as an emergency procedure, and laparoscopy is the dominating technique in both the planned (94%) and the emergency (82%) setting.…”

Incidence and risk factors for symptomatic venous thromboembolism following cholecystectomy

“…The coverage in regards to patients undergoing cholecystectomy is high in both GallRiks (82.9 %) and PAR (95.6 %). Furthermore, GallRiks has been validated with an overall correctness of registration in 97.2-98.2 % [23].…”

“…The register is continuously validated by independent observers in a blinded review of patient records at each participating hospital. Previous reviews have shown a high validity, with correct registrations and conformity with medical records in 97.9 % of all cases [13,23].…”

414 The Sooner the Better-The Importance of Optimal Timing of Cholecystectomy in Acute Cholecystitis. Data From the National Swedish Registry for Gallstone Surgery, Gallriks (2006 to 2014)

“…The validation of GallRiks has demonstrated high correctness and completeness of data and no failure to report serious adverse events. 23 The registry attained an overall national coverage of approximately 90 % during the actual enrolment period.…”
