Electronic phenotyping has been previously described for BMI in EAGLE BioVU [42 ]. To extract lipid and type 2 diabetes traits from EAGLE BioVU EMRs, laboratory measurements were queried for glucose, HbA1c, HDL-C, insulin, LDL-C, total cholesterol, and triglycerides. Records were also queried for calculated LDL-C. Prescription medication is available in the SD through MedEx [43 (link)], an algorithm that extracts medications and their signature mentions from free-text entries available in the EMR.
For each adult patient (>18 years), median values were calculated for a) measurements taken when no medications are prescribed (“pre-medication” values) and b) measurements taken at first mention of medication and post mention of medication (“post-medication” values). We used the following medication class and list to identify lipid measurements determined at the time or after patients were prescribed lipid-lowering medications
Statins (also known as HMG CoA reductase inhibitors, atorvastatin (Lipitor®), fluvastatin (Lescol®), lovastatin (Mevacor®, Altoprev™), pravastatin (Pravachol®), rosuvastatin calcium (Crestor®), simvastatin (Zocor®), lovastatin + niacin (Advicor®), atorvastatin + amlodipine (Caduet®), and simvastatin + ezetimibe (Vytorin™)
Selective cholesterol absorption inhibitors (ezetimibe (Zetia®))
Resins (cholestyramine (Questran®, Questran® Light, Prevalite®, Locholest®, Locholest® Light), colestipol (Colestid®), colesevelam Hcl (WelChol®))
Fibrates (gemfibrozil (Lopid®), fenofibrate (Antara®, Lofibra®, Tricor®, and Triglide™), clofibrate (Atromid-S))
Niacin
