| Summary | This study sought to estimate the positive predictive value (PPV) and sensitivity of the ICD-10 code G12.2 for identifying ALS mortalities. Death certificate data were obtained from the SC Budget and Control Board Office of Research and Statistics to estimate the PPV and sensitivity of the ICD-10 code G12.2 to identify potential cases of ALS in SC, compared to a known cohort of ALS patients. The estimated sensitivity was 85% and the PPV was 65%. While there are validity issues using mortality data, these findings suggest that mortality data can be used in the development of case-finding algorithms to identify PALS. |
