Developing an Inpatient Electronic Medical Record Phenotype for Hospital-Acquired Pressure Injuries: Case Study Using Natural Language Processing Models

To fairly compare our method with ICD-based PI identification algorithms, the classification threshold was tuned to achieve similarly estimated specificities (0.988 and 0.959) of 2 ICD-based algorithms developed and validated in a previous study by Ho et al [1]. The first case definition is more specific and yields greater detection precision. The second definition is more inclusive of nonspecific codes for wounds and is likely to capture a larger number of cases.
