Classifying Perinatal Advanced Practice Data With the Omaha System

This pilot study analyzed perinatal advanced practice registered nurse (APRN) diagnoses/client problems and interventions across sites using standardized terminology. APRN verbatim encounter logs from 8 patients in a previous study were coded by both the Omaha System and Current Procedural Terminology (CPT) codes. Previous outcomes were reduced preterm births, hospitalizations, and costs (Brooten et al., 2001). In 597 encounters (63% by telephone), 27 diagnoses and 8,077 interventions were recorded.

When coded with CPT, more than 80% of interventions were unlisted. Documentation using standardi...
