Identification of Pregnant Women in the Sentinel Distributed Database and Determination of Drug Use Among Pregnant and Non-Pregnant Women – ICD-10-CM Pregnancy Tool Algorithm Update

The Sentinel Operations Center (SOC) recently implemented a “drug use during pregnancy” type of analysis into its core routine analytic framework program, the Cohort Identification and Descriptive Analysis (CIDA) tool. As a result of this, all analytic functionality and approaches currently available within CIDA are available for future requests to characterize drug use during pregnancy. However, because the Pregnancy Tool algorithm to identify livebirths was developed using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes, its utility in requests with query periods beyond September 30, 2015 is limited. A workgroup was created to update the ICD-9-CM code algorithms used to identify livebirths to ICD-10-CM, so that the updated algorithm may be applied (no tool modification is needed).

This activity consists of two parts: 

• Part A, the workgroup will develop the ICD-10-CM algorithm to identify livebirths.
• Part B, the workgroup will run one pilot query to test that the appropriate inputs for the ICD-10-CM algorithm are applied with CIDA.
