Modernizing tuberculosis risk assessments for health care systems: Utilizing ICD-10 diagnostic codes for a site-based approach.

Exposure to tuberculosis (TB) in healthcare settings can pose a significant risk to patients, families, and health care personnel. The Centers for Disease Control and Prevention recommend that healthcare facilities perform an annual TB risk assessment but do not offer methods to encompass larger health care systems with geographically diverse facilities. We sought to develop a supplemental risk assessment strategy utilizing ICD-10-CM codes to quantify TB risk for individual sites across our health care system.
