Journal ArticleDOI
Comorbidity measures for use with administrative data.
TL;DR: The present method addresses some of the limitations of previous measures and produces an expanded set of comorbidities that easily is applied without further refinement to administrative data for a wide range of diseases.

Coding algorithms for defining comorbidities in ICD-9-CM and ICD-10 administrative data.
Hude Quan,Vijaya Sundararajan,Patricia Halfon,Andrew Fong,Bernard Burnand,Jean-Christophe Luthi,L. Duncan Saunders,Cynthia A. Beck,Thomas E Feasby,William A. Ghali +9 more
TL;DR: A multistep process to develop ICD-10 coding algorithms to define Charlson and Elixhauser comorbidities in administrative data and assess the performance of the resulting algorithms found these newly developed algorithms produce similar estimates ofComorbidity prevalence in administrativeData, and may outperform existing I CD-9-CM coding algorithms.

Epidemiology of severe sepsis in the United States: analysis of incidence, outcome, and associated costs of care.
Derek C. Angus,Walter T. Linde-Zwirble,Jeffrey Lidicker,Gilles Clermont,Joseph A. Carcillo,Michael R. Pinsky +5 more
TL;DR: Severe sepsis is a common, expensive, and frequently fatal condition, with as many deaths annually as those from acute myocardial infarction, and is especially common in the elderly and is likely to increase substantially as the U.S. population ages.

Updating and Validating the Charlson Comorbidity Index and Score for Risk Adjustment in Hospital Discharge Abstracts Using Data From 6 Countries
Hude Quan,Bing Li,Chantal Marie Couris,Kiyohide Fushimi,Patrick Graham,Phil Hider,Jean-Marie Januel,Vijaya Sundararajan +7 more
TL;DR: The updated Charlson index of 12 comorbidities showed good-to-excellent discrimination in predicting in-hospital mortality in data from 6 countries and may be more appropriate for use with more recent administrative data.

Delirium as a predictor of mortality in mechanically ventilated patients in the intensive care unit
E. Wesley Ely,Ayumi Shintani,Brenda Truman,Theodore Speroff,Sharon M. Gordon,Frank E. Harrell,Sharon K. Inouye,Gordon R. Bernard,Robert S. Dittus +8 more
TL;DR: Delirium was an independent predictor of higher 6-month mortality and longer hospital stay even after adjusting for relevant covariates including coma, sedatives, and analgesics in patients receiving mechanical ventilation.

A new method of classifying prognostic comorbidity in longitudinal studies: Development and validation☆
TL;DR: The method of classifying comorbidity provides a simple, readily applicable and valid method of estimating risk of death fromComorbid disease for use in longitudinal studies and further work in larger populations is still required to refine the approach.

Surgery for lumbar spinal stenosis. Attempted meta-analysis of the literature.
TL;DR: A meta-analysis was undertaken to determine the effects of surgery for lumbar spinal stenosis on pain and disability, and few patient characteristics were found to predict outcome.

The importance of classifying initial co-morbidity in evaluating the outcome of diabetes mellitus
TL;DR: Among 5-yr survivors, the occurrence rate of new vascular events (or ‘diabetic complications’) was directly related to the same features of age and co-morbidity that seemed to affect fatality.

Patient Outcomes After Lumbar Spinal Fusions
Judith A. Turner,Mary Ersek,Larry D. Herron,Jodie K. Haselkorn,Jodie K. Haselkorn,Daniel L. Kent,Daniel L. Kent,Marcia A. Ciol,Richard A. Deyo +8 more
TL;DR: Clinical outcomes did not differ by diagnosis or fusion technique, but were worse in studies with a greater number of previously operated patients, and complications of fusions are common.

Accuracy of Diagnostic Coding for Medicare Patients under the Prospective-Payment System
TL;DR: The study studied the accuracy of the coding for diagnosis-related groups (DRGs) in hospitals receiving Medicare reimbursement during the period October 1984 through March 1985, revealing an error rate of 20.8 percent in DRG coding.
