  • * Patient-level covariates included age and gender; practice-level covariates included whether the practice uses an EMR and whether the practice is a solo or group practice.

  • Among patients with a heart condition, the odds of appropriate assessment according to guidelines increased by 8% with a 1-point increase (on a scale of 1 to 5) for use of patient identification systems. (Not significant, P = 0.768.)

  • Use of information system component associated with improved diabetes care.
