Wastes in U.S. Healthcare System Estimated ranges of total annual cost of waste in the U.S. Health Care system: • Administrative complexity: $265.6 billion • Pricing failure: $230.7 billion - $240.5 billion • Failure of care: $102.4 billion - $165.7 billion • Overtreatment: $75.7 billion - $101.2 billion • Fraud and abuse: $58.5 billion - $83.9 billion • Failure of care coordination: $27.2 billion - $78.2 billion Shrank WH, et al.

Case Study I: Breast Cancer Risk Assessment • ~24 million mammograms done annually in the U.S. • ~266,600 new cases of invasive breast cancer diagnosed in U.S. annually in the U.S. • False positive rate from mammogram is estimated to be 7% 7%~1 ~10% 0%. 1 • 55%–85% of breast biopsies showed benign lesions for BI-RADS 4 (2-95% 95% chance of malignancy ). ). • False positive mammograms is estimated to cost ~ $4 b billion an annual nually. 2 • Patients who have received false-positive diagnoses have shown to exhibit a higher level of anxiety and lower level of self-esteem . 1. https://www.cancer.gov/types/breast/hp/breast-screening-pdq 2. https://www.healthaffairs.org/doi/full/10.1377/hlthaff.2014.1087
