Nowinski examined six quality indicators as the primary outcome for the EHR intervention: initial antibiotic dose within four hours of hospital arrival for pneumonia patients; fall rate per 1000 patient-days; chest pain pathway-discharged within 23 hours of admission; annual Hemoglobin A1c (HgA1c) measurement in diabetic patients; left ventricular function evaluation on a yearly basis; and appropriate use/non-use of angiotensin-converting-enzyme (ACE) inhibitors at discharge for patients with Chronic Heart Failure (CHF). This evidence concerns the gene ACE and pneumonia.
