Median Score 1–3: Rarely Appropriate care for specific indication (treatment is not generally acceptable and is not a reasonable approach for the indication). Median Score 4–6: May Be Appropriate care for specific indication (treatment may be generally acceptable and may be a reasonable approach for the indication). Median Score 7–9: Appropriate care for specific indication (treatment is generally acceptable and is a reasonable approach for the indication).
