TLDR
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.Abstract:
Objectives:Implementation of the International Statistical Classification of Disease and Related Health Problems, 10th Revision (ICD-10) coding system presents challenges for using administrative data. Recognizing this, we conducted a multistep process to develop ICD-10 coding algorithms to define Cread more

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.

TL;DR: To evaluate the validity of clinical criteria to identify patients with suspected infection who are at risk of sepsis, a new model derived using multivariable logistic regression in a split sample was derived.

Long-term Cognitive Impairment and Functional Disability Among Survivors of Severe Sepsis
TL;DR: Severe sepsis in this older population was independently associated with substantial and persistent new cognitive impairment and functional disability among survivors, likely resulting in a pivotal downturn in patients' ability to live independently.

TL;DR: Differences in patient to nurse ratios and nurses' educational qualifications in nine of the 12 RN4CAST countries with similar patient discharge data were associated with variation in hospital mortality after common surgical procedures, implying an increased emphasis on bachelor's education for nurses could reduce preventable hospital deaths.
Journal ArticleDOI
A modification of the Elixhauser comorbidity measures into a point system for hospital death using administrative data.
TL;DR: The Elixhauser comorbidity system can be condensed to a single numeric score that summarizes disease burden and is adequately discriminative for death in hospital when analyzing administrative data.

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.

Comparing the areas under two or more correlated receiver operating characteristic curves: a nonparametric approach.
TL;DR: A nonparametric approach to the analysis of areas under correlated ROC curves is presented, by using the theory on generalized U-statistics to generate an estimated covariance matrix.

Adapting a clinical comorbidity index for use with ICD-9-CM administrative databases
TL;DR: It is concluded that the adapted comorbidity index will be useful in studies of disease outcome and resource use employing administrative databases.

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.
International statistical classification of diseases and related health problems. Tenth revision.
TL;DR: It is proposed that the chapters on external causes of injury and poisoning, and factors influencing health status and contact with health services, should form an integral part of ICD-10, for the first time in its history based on an alphanumeric coding scheme.
