Ischemic Vascular Disease: All-or-None Outcome Measure (Optimal Control)  This is a measure developed by the Wisconsin Collaborative for Healthcare Quality (WCHQ).

The results below represent 84,847 patients with coronary and other atherosclerotic vascular disease.

The All-Or-None method is a more complete way of reporting the IVD measure and has multiple goals. All goals must be reached by each patient in order to meet the measure.

The IVD All-or-None Measure is one outcome measure (optimal control). The measure contains four goals. All four goals within a measure must be reached in order to meet that measure. The numerator for the all-or-none measure should be collected from the organization's total IVD denominator.

All-or-None Outcome Measure (Optimal Control) - Using the IVD denominator optimal results include:

  • Most recent blood pressure measurement is less than 140/90 mm Hg -- And
  • Most recent tobacco status is Tobacco Free -- And
  • Daily Aspirin or Other Antiplatelet Unless Contraindicated -- And
  • Statin Use

Why use an All-or-None method?

This method was chosen because of the benefits it provides to both the patient and the practitioner. First, this methodology more closely reflects the interests and likely desires of the patient. With the data collected in two scores (optimal testing and optimal results), patients can easily look and see how their provider group is performing on these criteria rather than trying to make sense of multiple scores on individual measures. Second, this method represents a systems perspective emphasizing the importance of optimal care through a patient's entire healthcare experience. Third, this method gives a more sensitive scale for improvement. For those organizations scoring high marks on individual measures, the All-or-None measure will give room for benchmarks and additional improvements to be made.
