19. Comparison of cause of death between ANZDATA and the Australian national death index

Author

Sypek, Matthew P, Dansie, Kathryn B, Clayton, Phil, Webster, Angela C, and Mcdonald, Stephen

Abstract

Aim: The aim of the present study was to understand the differences in how cause of death for patients receiving renal replacement therapy in Australia is recorded in The Australian and New Zealand Dialysis and Transplant Registry (ANZDATA) compared to the National Death Index (NDI). Methods: Data linkage was performed between ANZDATA and NDI for all deaths in the period 1980-2013. Cause of death was classified according to ICD-10 chapter. Overall and chapter specific agreement were assessed using the Kappa statistic. Descriptive analysis was used to explore differences where there was disagreement on primary cause of death. Results: The analysis cohort included 28 675 patients. Ninety five percent of ANZDATA reported deaths fell within +/- 3 days of the date recorded by NDI. Circulatory death was the most common cause of death in both databases (ANZDATA 48%, NDI 32%). Overall agreement at ICD chapter level of primary cause was poor (36%, kappa 0.22). Agreement was best for malignancy (kappa 0.71). When there was disagreement on primary cause of death these were most commonly coded as genitourinary (35%) and endocrine (25.0%) in NDI, and circulatory (39%) and withdrawal (24%) in ANZDATA. Sixty-nine percent of patients had a renal related cause documented as either primary or a contributing cause of death in the NDI. Conclusion: There is poor agreement in primary cause of death between ANZDATA and NDI which is in part explained by the absence of diabetes and renal failure as causes of death in ANZDATA and the absence of 'withdrawal' in NDI. These differences should be appreciated when interpreting epidemiological data on cause of death in the Australian end stage kidney disease population.

28. Changing survival of people with myeloma and end stage kidney disease; a cohort study using ANZDATA 1963-2013

Author

Webster, Angela C, Irish, Ashley B, and Kelly, Patrick J

Abstract

Background It is unclear whether recent advances in myeloma therapy have improved survival for all those with myeloma and end stage kidney disease (ESKD). Methods Population‐based registry cohort study using Australia and New Zealand Dialysis and Transplant Registry data 1963–2013. We measured survival of people with myeloma and other plasma cell dyscrasias and ESKD over time, and investigated prognostic factors for improved survival using survival analysis (results expressed as hazard ratios (HR) with 95% confidence intervals). Results We included 65 940 people (207 595 person‐years); 1067 people (1.6%) with myeloma and 572 (0.9%) with other plasma cell dyscrasia. Myeloma ESKD rose from 0.8% before 1994 to 2.2% in 2004 and remained stable. People with myeloma were older, and age increased over time, from 62.5 before 1994 to 70.1 years from 2010, but the non‐myeloma group age increased more steeply (52.0 before 1994; 62.2 from 2010). In myeloma patients, survival improved (P < 0.001) with recent predicted 5 year survival of 27.5% aged

42. Efficient strategies to find diagnostic test accuracy studies in kidney journals

Author

Rogerson, Thomas E, Ladhani, Maleeka, Mitchell, Ruth, Craig, Jonathan C., and Webster, Angela C

Abstract

Aim Nephrologists looking for quick answers to diagnostic clinical questions in MEDLINE can use a range of published search strategies or Clinical Query limits to improve the precision of their searches. We aimed to evaluate existing search strategies for finding diagnostic test accuracy studies in nephrology journals. Methods We assessed the accuracy of 14 search strategies for retrieving diagnostic test accuracy studies from three nephrology journals indexed in MEDLINE. Two investigators hand searched the same journals to create a reference set of diagnostic test accuracy studies to compare search strategy results against. Results We identified 103 diagnostic test accuracy studies, accounting for 2.1% of all studies published. The most specific search strategy was the Narrow Clinical Queries limit (sensitivity: 0.20, 95% CI 0.13–0.29; specificity: 0.99, 95% CI 0.99–0.99). Using the Narrow Clinical Queries limit, a searcher would need to screen three (95% CI 2–6) articles to find one diagnostic study. The most sensitive search strategy was van der Weijden 1999 Extended (sensitivity: 0.95; 95% CI 0.89–0.98; specificity 0.55, 95% CI 0.53–0.56) but required a searcher to screen 24 (95% CI 23–26) articles to find one diagnostic study. Bachmann 2002 was the best balanced search strategy, which was sensitive (0.88, 95% CI 0.81–0.94), but also specific (0.74, 95% CI 0.73–0.75), with a number needed to screen of 15 (95% CI 14–17). Conclusion Diagnostic studies are infrequently published in nephrology journals. The addition of a strategy for diagnostic studies to a subject search strategy in MEDLINE may reduce the records needed to screen while preserving adequate search sensitivity for routine clinical use.

49. Systematic reviews of surgical procedures in children: Quantity, coverage and quality

Author

McGee, Richard G, Craig, Jonathan C, Rogerson, Thomas E, and Webster, Angela C

Abstract

Aim Systematic reviews have the potential to map those areas where children are under‐represented in surgical research. We aimed to describe and evaluate the quantity, coverage and the quality of conduct and reporting of systematic reviews of surgical procedures in children. Methods We searched four biomedical databases, a systematic review register, reference lists and conducted hand searching to identify relevant reviews. Two reviewers worked independently to critically appraise included studies and abstract data. We assessed reporting quality using the preferred reporting items for systematic reviews and meta‐analysis statement and methodological quality using the Assessment of Multiple SysTemAtic Reviews tool. Results Fifteen systematic reviews were identified, representing 0.01% of all paediatric surgical citations in MEDLINE and E mbase. Thirteen of the reviews were C ochrane reviews, and most reviews (12/15) addressed subspecialty interests such as otorhinolaryngology. The median number of included trials per systematic review was four (interquartile range 1 to 9.5), the median number of primary outcomes was 5.5 (interquartile range 3.5 to 7.5). In general, reporting and methodological quality was good although there were several omissions, particularly around completeness of reporting of statistical methods used, and utilisation of quality assessments in analyses. Outcomes were often not clearly defined and descriptions of procedures lacked sufficient detail to determine the similarities and differences among surgical procedures within the contributing trials. Conclusion Systematic reviews of surgical procedures in children are rarely published. To improve the evidence base and guide research agendas, more systematic reviews should be conducted, using standard guidelines for conduct and reporting.
