Selects patients with presumptive Alzheimer's disease. The algorithm is looking for records with a minimum of 5 visits with the Diagnosis of interest, using ICD 9 codes OR a dementia drug fill.This algorithm was validated against a curated research cohort.
Project Outline: Selection of all Caucasian patients with hypothyroidism without a secondary cause of surgical removal or radiological ablation. The search is designed to eliminate subclinical hypothyroidism (by requiring that patients be on a replacement medication), medication-induced hypothyroidism (e.g., PTU, lithium, or history of amiodarone), and transient causes (e.g., pregnancy or subacute thyroiditis).
Genetic variation that predicts white blood count (WBC) and it differential, a marker of the health of the immune system.
WBC is unique among the identified inflammatory predictors of chronic disease in that it has been routinely measured in healthy patients in an unbiased way for the duration of the electronic medical record data.
