Inclusion Criteria for Case Definition
A patient must have all the below:
 288.03, 288.00, or 288.09
 ANC < (1500, 1000, 500) for (mild, moderate, severe) as below
 Presence of an affecting medication within 30 days before or 3 days after
the low ANC count
- Check for subjects with the following ICD-9 codes:
288.03 Drug induced neutropenia
Use additional E code to identify drug
- Absolute Neutrophil Count (ANC) measured in cells per microliter of blood:
The lower limit of the reference value for ANC in adults varies in different
laboratories from 1.5-1.8 109/L or 1500-1800/µL (mm3). For practical
purposes, a value lower than 1500 cells/µL is generally used to define
neutropenia. Age, race, genetic background, environment, and other
factors can influence the neutrophil count. For example, blacks may have
a lower but normal ANC value of 1000 cells/µL, with a normal or low total
WBC count.
Neutropenia is classified as mild, moderate, or severe, based on the ANC
as follows:
Mild Neutropenia: (1000 <= ANC < 1500) — mild
Moderate Neutropenia: (500 <= ANC < 1000) — moderate risk of infection
Severe Neutropenia: (ANC < 500) — severe risk of infection
