What is the overall performance of SOIC?
NIOSH conducted a comparison of SOIC and an expert’s manually assigned codes for 48,067 cases from a death certificate based surveillance system. The number of software-assigned codes that matched the expert manual coder is shown below. In this test there was no adjudication of the results; that is, the mismatched cases were not reviewed to determine if the SOIC autocoder or the manual coder was actually correct. These results are provided as an illustration. Coding results will vary and depend upon overall data quality. The software does not perform well on narratives with company names and other ambiguous information.
