Table 2. Measures for Quality Profiling of Physician Organizations.

Quality Indicator	Measure
Diabetes Mellitus	HbA1c Management: Percentage of diabetic patients with one or more HbA1c tests. Lipid Measurement: Percentage of diabetic patients with at least one low-density lipoprotein (LDL) cholesterol test. Urine Protein Testing: Percentage of diabetic patients with at least one test for microalbumin during the measurement year; or who had evidence of medical attention for existing nephropathy (diagnosis of nephropathy or documentation of microalbuminuria or albuminuria). Eye Exam: Percentage of diabetic patients who received a dilated eye exam or seven standard stereoscopic photos with interpretation by an optometrist or ophthalmologist or imaging validated to match diagnosis from these photos during the reporting year, or during the prior year if the patient is at low risk for retinopathy. A patient is considered low risk if the following criterion is met: has no evidence of retinopathy in the prior year. (This measure is adapted for claims data measurement.)
Heart Failure	Left Ventricular Ejection Fraction Testing: Percentage of patients hospitalized with a principal diagnosis of heart failure during the current year who had left ventricular ejection fraction testing during the current year.
Coronary Artery Disease	Lipid Profile: Percentage of coronary artery disease patients receiving at least one lipid profile during the reporting year.
Preventive Care	Breast Cancer Screening: Percentage of female beneficiaries age 50-69 who had a mammogram during the measurement year or the year prior to the measurement year.

NOTE: Two of the measures—eye exam and mammography—are specified as 2-year measures, but we used the single year of claims data available to us to calculate them, implying that our estimates of these measures are biased downward (lower bounds).
