BACKGROUND We have previously described a method for dealing with missing data in a prospective cardiac registry initiative. The method involves merging registry data to corresponding ICD-9-CM administrative data to fill in missing data 'holes'. Here, we describe the process of translating our data merging solution to ICD-10, and then validating its performance. METHODS A multi-step translati...

In this paper we present our research efforts and obtained results within the CLEF eHealth challenge 2017, Track 1. The task involves the recognition and mapping of ICD-10 codes to English and French death certificates. Our approach proposes a two tier, two stage process. First, we use a rule-based system, based on handcrafted rules and the use of Apache Solr, to perform ICD-10 code Named Entit...

Coding productivity is expected to drop significantly during the lead-up to and in the initial stages of ICD-10-CM/PCS implementation, now expected to be delayed until October 1, 2015. This study examined the differences in coding productivity between ICD-9-CM and ICD-10-CM/PCS for hospital inpatient cases matched for complexity and severity. Additionally, interrater reliability was calculated ...

At the same time they do not want to be divorced from the needs of the medical community ...

SAMPLING AND METHODS Using the Composite International Diagnostic Interview, two train...
