01/14MODULE: PROBLEM SPACE

The Problem

Mild respiratory symptoms trigger X-rays and antibiotics.

OVER-ORDERING
  • • Chest X-rays for colds
  • • Antibiotics without indication
  • • Repeat imaging for stable cases
COST IMPACT
  • • $180 per unnecessary X-ray
  • • $50 per unnecessary antibiotic
  • • Delayed care for true cases
REDUCTION TARGET
35-50%
