I am unable to calculate an indicator relating to some interventions in the healthcare field.
In particular, my goal is to calculate the number of interventions that have the following characteristics: all hospitalizations with main and secondary diagnoses (5 fields) with ICD-9-CM codes 174.x, 198.81, 233.0 and interventions for breast cancer defined by at least one of the ICD-9-CM codes in any position (5 fields): 85.2x, 85.33-85.36,85.4x.
How can I set up set analysis?
This is my "trace": count( {< Year={$(=max(Year))}, type={'1', '4'}, priority={"A"}, principal_diagn = {$(cod_diagnosys)}, principal_int = {$(cod_int)} > id)
