Cost & Quality Problems

Medical Harm

A critically important area of excess spending and patient suffering is connected to care that is not only unnecessary, but harmful to patients. Preventing medical harm is also referred to as the practice of patient safety.1 

In 1999, the Institute of Medicine (IOM) estimated that 98,000 patients anually lose their lives due to medical harm.2 The IOM report sounded an alarm to the country, calling for sweeping changes to the healthcare system to improve patient safety.

While there has been some progress since the IOM's report,3 multiple studies confirm that progress is far too slow.4 Moreover, the IOM likely underestimated the amount of medical harm patients experience each year. 

What is Medical Harm?

Among other things, medical harm includes:

  • serious reportable events—more commonly called “never events;”5
  • healthcare acquired conditions (HACs);
  • healthcare-acquired infections (HAIs);
  • medication errors; and
  • diagnostic errors.

Definitions can be tricky.6 Not all medical harm is preventable. For example, an adverse drug reaction can occur when there was no error in the process of prescribing the drug to a patient.7 Moreover, medical error is a failure in the delivery of medical care, regardless of the outcome. Therefore, it includes errors that did and did not result in harm.8 

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 from hospitals. 

Preventable hospital readmissions — another source of wasteful spending — are in a category that is different from medical harm, but these are often connected to hospital-acquired infections and other types of medical harm. 

While known to be large, precise extent of harm not is measured

Of grave concern, while known to be a large problem, there has 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. The precise number of medical harm events is debated and likely underestimated. Death certificates do not include a field to report if a patient died due to reasons related to medical error.9 

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.

  • A 2019 meta-analysis found that 1 in 20 patients experience preventable medical harm and this harm leads to disability or death around 12 percent of the time.10 
  • A 2013 study estimated that medical harm kills 210,000 to 440,000 patients each year.11 
  • Annually, preventable medication errors likely affect more than 7 million patients and cost about $21 billion.12 

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:

  • Improving the accuracy, breadth and standardization of publicly reported medical harm across all settings.
  • Funding training and education of healthcare providers to understand the most effective strategies for reducing medical harm.
  • Aligning financial incentives to harm reduction, such as no payment for serious reportable events, reducing payments to the lowest performers and bundling payments in patient-centered integrated health delivery systems.
  • Make the National Practicioner Data Bank — a database of all state and federal actions against US physicians, including malpractice settlements — available to the public. Currently, the data is available, but the names of doctors are confidential.13
  • Establish a National Patient Safety Board — similar to the National Transportation Safety Board and the Consumer Finance Protection Agency — to represent the interests of patients/consumers by monitoring, investigating and promoting healthcare system changes that will lead to the elimination of medical errors.
