Patient Condition/Event Flags

On the Insights dashboard of each HARP module, where available, Patient Condition/Event filtering identifies patients with a relevant diagnosis in their medical history to allow for enhanced population-level filtering. These flags are identified in several ways.

The following Patient Condition/Event flags are identified within HealthInfoNet's Predictive Risk Modeling | Interpreting Risk Models for patients who have a diagnosis of the condition/event (i.e. with a risk class of “Present” and a risk score of 100):

Alzheimer’s Disease
Cardiac Dysrhythmias
Chronic Kidney Disease
Chronic Obstructive Pulmonary Disease
Congestive Heart Failure
End-Stage Renal Disease
Hypertension
Lung Cancer
Type 2 Diabetes

Additionally, the following Patient Condition/Event flags were developed in partnership with Maine CDC. Specifications for these can be found below.
