PPO DescriptionPercentage of Total PPOs (N = 55,578)a
  1.Start laxatives in patients receiving opioids regularly14.7
  2.Start ACE inhibitor with systolic heart failure and/or documented coronary artery disease  7.9
  3.Start statin therapy with a documented history of coronary, cerebral, or peripheral vascular disease, unless patient has end-of-life status or is >85 years old  7.4
  4.Start ACE inhibitor or ARB (if intolerant of ACE inhibitor) in diabetes with evidence of renal disease, that is, dipstick proteinuria or microalbuminuria (>30 mg/24 hours) with or without serum biochemical renal impairment  7.1
  5.Start metformin twice a day with diabetes mellitus type 2 if eGFR is 30-50 mL/min/1.73m2, not if < 30 mL/min/1.73m2  6.5
  6.Start antiplatelet therapy (aspirin, clopidogrel, prasugrel, or ticagrelor) with a documented history of coronary, cerebral, or peripheral vascular disease  5.9
  7.Start aspirin (75-160 mg once daily) in the presence of chronic atrial fibrillation, where vitamin K antagonists or direct thrombin inhibitors or factor Xa inhibitors are contraindicated  5.6
  8.Start β-blocker with ischemic heart disease  5.1
  9.Start vitamin D supplement in older adults who are housebound, are experiencing falls, or have osteopenia (bone mineral density T-score is greater than −2.5 but less than −1.0 in multiple sites)  4.9
10.Start regular inhaled β2 agonist or antimuscarinic bronchodilator (eg, ipratropium, tiotropium) for mild to moderate asthma or COPD  4.8
  • ACE = angiotensin-converting enzyme; ARB = angiotensin receptor blocker; COPD = chronic obstructive pulmonary disease; eGFR = estimated glomerular filtration rate; PPO = potential prescribing omission.

  • Note: PPOs provide information on correct prescribing according to the Screening Tool to Alert doctors to Right Treatment (START) criteria.

  • a Unique PPOs per patient over 6 years.
