Data presentation for quality improvement.
Efforts to improve quality of medical care often involve large data sets. Reviewing laboratory results over time for a cohort of patients is particularly problematic: traditional statistics conflate case to case variations with day to day variations (within a case). To help solve this problem, we propose using sparklines for case by case review and a modified box-plot for overall data review. We demonstrate these data presentations using fingerstick glucose values.
