A critically important area of excess spending and patient suffering is connected to care that is not only unnecessary but actually harms patients.
In 1999, the Institute of Medicine (IOM) estimated that annually 98,000 patients lost their lives due to medical harm.1 The IOM report sounded an alarm to the country, calling for sweeping changes to the health-care system to improve patient safety.
More recently, three landmark studies revealed no significant progress in improving the safety of patients since the IOM’s report and that the IOM greatly underestimated the amount of medical harm patients experience each year.2 The studies looked at all harm—from minor to major—and emphasized the need for a focus on a broader definition of medical harm. Today, our best estimates show that preventable patient harm may be the third-leading cause of death in America.
What is Medical Harm?
Among other things, medical harm3 includes:
While medical harm spans all providers – hospitals, doctors, dialysis centers, nursing homes and outpatient surgical centers—most of what we know of this harm is about hospitals.
Preventable hospital readmissions—another source of wasteful spending—are different, but often connected to hospital-acquired infections and other types of errors.
While known to be large, precise extent of harm not is measured
Of grave concern, while known to be a large problem there’s never been an actual count of how many patients are harmed while receiving medical care. Public hospital reporting systems and internal peer-review capture only a fraction of patient harm or negligent care.
Similarly, there are no comprehensive assessments of the costs that medical errors add to our nation’s healthcare bill. Most studies are limited to the cost of a particular type of event or a particular population. However, we do know that the limited resources devoted to prevention—by hospitals, other healthcare providers and governmental agencies at the state and federal levels—are dwarfed by the resources spent to treat the consequences of this mostly preventable problem. Beyond finances, the human cost is staggering.
The following information provides a partial picture of the cost of medical harm.
Strategies to Address Medical Harm
The strategies that help reduce patient harm are fairly well understood but unevenly implemented. Key strategies to measure and reduce medical harm include:
