I am working with the national readmission database in SPSS. HCUP gives out an Elixhauser Comorbidity Software Refined for ICD-10-CM diagnosis codes to identify comorbidities for the patient population, however this software is only usable in SAS (which I don’t have). In order to identify comorbidity frequencies, according to HCUP, there are 18 comorbidities (within the elixhauser comorbidity index) that can only be identified using present on admission (POA) indicators: basically specifies whether the diagnosis was prior medical history or if it occurred during the hospital stay (POA indicator is binary yes or no). However, these indicators are not present in the SPSS file.
Anyone know a solution? Is the use of POA indicators necessary in NRD (this software isn’t specific to NRD and can also be used in NIS)?
