Identifying Cases of Sleep Disorders through International Classification of Diseases (ICD) Codes in Administrative Data.
International journal of population data science(2018)
Abstract
Sleep disorders in administrative data can be identified mainly through physician claims data and with some being determined through outpatient/ambulatory care data ICD codes, however these are poorly coded within inpatient data sources. This may be a function of how sleep disorders are diagnosed and/or reported by physicians in inpatient and outpatient settings within medical records. Future work to optimize administrative data case definitions through data linkage are needed.
