“…127 CIHI diagnostic codes in general have demonstrated high agreement for both primary (81-95%) and secondary (88-99%) diagnoses. 128 The OHIP physician billings claims and associated diagnostic code for CKD were compared to the medical record and demonstrated a sensitivity of 74%, specificity of 99%, positive predictive value of 29%, and negative predictive value of 99%.…”

The surgical management of renal masses involves either radical nephrectomy (RN) or partial nephrectomy (PN). PN has been associated with better long-term renal function, and has also been linked to improved cardiac morbidity and overall survival. However, the relationship between treatment choice and definitive outcomes of chronic kidney disease (CKD) are lacking. Our aim was to examine whether PN is associated with a lower risk of end-stage renal disease (ESRD) requiring renal replacement therapy.We performed a population-based, retrospective cohort study with data from linked administrative databases in the province of Ontario, Canada. We included individuals with pathologically confirmed renal cell carcinoma (RCC) diagnosed between 1995 and 2010. Cox proportional hazards (PH) models, propensity score models, and competing risks models were used to assess the impact of treatment choice. PN compared to RN reduces the risk of ESRD requiring renal replacement therapy in a modern cohort of patients (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010). PN is associated with a lower risk of new-onset CKD, lower risk of cardiac morbidity, and improved overall survival. We provide further evidence for the benefit of PN compared to RN, particularly related to definitive outcomes of renal failure.iii ACKNOWLEDGEMENTS

“…Seven studies accepted HF diagnosis documented in the chart (12,(16)(17)(18)(19)(20)(21) and four studies used documented HF diagnosis or a combination of clinical judgement based on information in the chart (eg, test results, diagnostics) (22)(23)(24)(25). Eight studies (15,(25)(26)(27)(28)(29)(30)(31) ascertained HF presence based on diagnostic criteria used by scoring systems from Framingham, Carlson, Boston, the National Health and Nutrition Examination Survey (NHANES), the New York Heart Association (NYHA) or the European Society of Cardiology (ESC). Four studies (25)(26)(27)32) further classified HF according to levels of evidence such as definite or possible HF using the ESC or Boston criteria.…”

“…Four studies (25)(26)(27)32) further classified HF according to levels of evidence such as definite or possible HF using the ESC or Boston criteria. Two studies compared the PPV against different clinical definitions of HF, and found that the PPV varied between criteria used (Lee et al [30], 94% Framingham versus 89% Carlson; McCullough et al [31], 56% NHANES versus 64% Framingham versus 83% NYHA).…”

H eart failure (HF) has been widely studied because of its high mortality and morbidity rates (1-4). Studies on HF have relied on multiple data sources such as surveys, disease registries, hospital charts and administrative data. Of these sources, administrative data have been increasingly used for health services utilization and outcome evaluation.Administrative data result from implementing health care delivery, enrolling members into health insurance plans and reimbursing health care providers for services (5). The types of administrative data depend on the health care system and the funding structure. For example, Canada has a nationally funded health care system that collects hospital discharge data at a national level, while insurance registry, physician services and emergency room visit information is collected at a provincial level. Although these data are not intended for research, they are widely used in surveillance and outcome studies. Therefore, the validity of the research results rely on the quality of the data. Data quality is critical for interpreting variation across studies from different geographical areas.The purpose of the present study was to systematically review the literature pertaining to the validity of administrative data for recording HF and apply the International Classification of Diseases (ICD) HF definitions to Canadian hospital discharge abstract data to explore the prevalence of HF across ICD code definitions. METHODSLiterature review Search strategy: Only English language articles that compared the validity of ICD codes in administrative databases (eg, physician claims data, hospital discharge) with a reference standard (eg, chart review, registry, survey, case notes) were included. The literature search focused on articles published from 1990 to 2008. To identify peerreviewed journal articles, both the Ovid MEDLINE database and EMBASE were searched. Because validation studies were not indexed consistently with standard MeSH terms, the following key search terms were used: 'admin data', 'administrative data', 'population surveillance', 'heart failure', 'congestive heart failure', 'hospital data', 'physician claims', 'claims', 'hospital discharge', 'validation' and 'registries'. Next, Boolean operators were used to join search terms within the database search engines to locate articles. The reference lists from these articles were scanned to identify any additional articles that met heAlth outcomes/public policy ©2010 Pulsus Group Inc. All rights reserved Twenty-one studies validated hospital discharge abstract data; three studies validated physician claims and two studies validated ambulatory care data. Eighteen studies reported sensitivity (range 29% to 89%). Specificity and negative predictive value were greater than 70% across 17 studies. Nineteen studies reported positive predictive values (range 12% to 100%). Ten studies reported kappa values (range 0.39 to 0.84).

“…This definition of HF hospitalization was shown to have a positive predictive value of 94% when compared to the Framingham criteria of HF. 16 Death from all causes is the most uncontroversial end point for a clinical trial to assess the achievement for therapeutic intervention in patients with HF. In subjects with previous HF, we also assessed deaths as a secondary outcome.…”

Comparison of Coding of Heart Failure and Comorbidities in Administrative and Clinical Data for Use in Outcomes Research

Abstract: The ICD-9 428 primary diagnosis is highly predictive of heart failure using clinical criteria. Examination of hospitalization data up to 1 year prior to the index admission improves comorbidity detection and may provide enhancements to future studies of heart failure mortality.
