In the largest, most comprehensive health care quality study ever conducted in the United States, RAND Health has documented that Americans with common health problems receive the "recommended care" just over 50% of the time.
This landmark study emphasizes that there are major gaps between best-known science and the care patients actually receive. The authors of the study conclude that, "The deficits we have identified in adherence to recommended processes for basic care pose serious threats to the health of the American public."
The consistent application of evidence-based care has been an area of concern among health care professionals and quality improvement advisors for decades. The health care system is extremely complex, and the consistent application of scientifically grounded best practices has, to date, not been its strongest suit. As a result, patients cannot expect to always receive evidence-based, effective care when they need it.
