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.

TL;DR: All of the ICD-10 versions of the Charlson algorithm performed satisfactorily, with the Quan version showing a trend toward outperforming the other versions in all data sets, and the distribution of comorbidity level categories was similar across the 3 translations.

TL;DR: Accuracy of administrative data in recording clinical conditions improved slightly between 1999 and 2003, demonstrating a phenomenon of improved administrative data accuracy that may relate to a coding 'learning curve' with the new coding system.

TL;DR: Readmission did not predict and was not a valid indicator of the quality of care for patients with heart failure admitted to three Swiss university hospitals.

TL;DR: The results show that ACEI use at discharge in patients with LVSD is associated with decreased rate of readmission, and suggest that compliance with the ACEI prescribing recommendations listed in clinical practice guidelines for patients with heart failure due to LVSD confers benefit.
