How well do algorithms and definitions identify heart failure using administrative and claims data?
How well do algorithms and definitions identify heart failure using administrative and claims data?
Administrative data algorithms perform well for identifying heart failure, especially when using primary hospital discharge diagnoses, and sensitivity can be improved by including outpatient codes.
No takes yet. Share an insight, caveat, or question.
Primary discharge diagnoses support reliable heart failure identification in claims data; confirms algorithm performance and supports outpatient codes to increase sensitivity.
