Medical Errors in America 2026
Medical errors are one of the most consequential and least publicly discussed health crises in the United States. The numbers are contested, the definitions are disputed, and the data is almost always underreported — but regardless of which estimate you use, the scale of preventable harm in American hospitals and clinics is staggering. The 1999 Institute of Medicine report To Err is Human put the figure at 44,000 to 98,000 deaths annually from preventable medical errors in hospitals, and it shocked the country. A 2013 study in the Journal of Patient Safety pushed that estimate to over 400,000 deaths per year. A 2016 BMJ paper claimed 251,454 or more, making medical errors the third leading cause of death in the US — a headline that dominated news cycles but was later criticized by researchers for methodological problems. The former director of AHRQ put the number closer to 75,000 preventable in-hospital deaths annually. Even that figure, the most conservative credible estimate from a government source, would make medical errors a leading killer. In 2026, the debate over exactly how many people die continues. What is not debatable is that the number is large, the harm is real, and the rate of serious incidents is going the wrong direction.
The most current verified data tells a specific story. The Joint Commission’s Sentinel Event Data 2024 Annual Review — released in July 2025 — found that serious patient safety incidents reported to the Commission rose 12% in a single year, reaching 1,575 reports. That covers only the events that facilities voluntarily reported to one oversight body. The CDC’s 2024 National Healthcare-Associated Infections (HAI) Data Report, released January 29, 2026, confirmed that roughly 1 in 31 hospital patients acquires an infection during their care on any given day. An AHRQ-funded study published in BMJ Quality and Safety found that 795,000 Americans die or become permanently disabled from diagnostic errors each year — 371,000 deaths and 424,000 permanent disabilities. A 2024 JAMA Internal Medicine study of seriously ill hospitalized adults found that 23% had a missed or delayed diagnosis, with 17% of those errors causing direct harm. These are not old statistics. They are the most current peer-reviewed and government-agency numbers available heading into mid-2026.

The honest way to read this table is to acknowledge that no single death figure for medical errors is both authoritative and precise. Every estimate involves methodological choices about what counts as a “preventable” error and how to attribute causation in patients who were already seriously ill. What the data does make clear is a set of harder facts: sentinel events reported to the Joint Commission rose 12% in a single year, patient falls as a share of all serious incidents nearly tripled between 2019 and 2024, wrong-site surgeries increased 13% in one year despite being entirely preventable with basic verification steps, and diagnostic errors kill or permanently disable 795,000 Americans annually by the most rigorous estimate in the published literature. That last number — from an AHRQ-funded study in BMJ Quality & Safety — is the one patient safety researchers currently consider the most methodologically sound for diagnostic harm specifically.
The cost data is worth sitting with too. Hospital-acquired infections alone cost $35.7 to $45 billion annually. Medication errors add $21 billion in direct medical costs. Defensive medicine — the practice of ordering unnecessary tests and procedures specifically to guard against malpractice liability — adds an estimated $46 billion annually to healthcare expenditures. When you add these up alongside malpractice premiums and legal costs, the total economic burden of medical errors in the US runs well into the hundreds of billions per year. And only about 5% of deaths from medical errors ever result in a malpractice payment. The NPDB recorded just 3,046 malpractice wrongful death payments in a recent reported year — against conservative estimates of tens of thousands of preventable in-hospital deaths annually.

The 2024 sentinel event data demands a plain reading before any analysis. In a single calendar year, Joint Commission-accredited facilities reported 776 patient falls serious enough to be classified as sentinel events — falls that resulted in severe harm or death — and 49 of those resulted in death, 503 in severe injury. Most involved patients 70 years or older and happened during walking, getting out of bed, or going to the bathroom. These are not exotic failure modes. They are failures of basic monitoring, staffing levels, and fall-risk communication. The fact that this category now accounts for 49% of all reported serious incidents — up from just 18% in 2019 — is one of the clearest signs that staffing pressures and post-pandemic care quality changes are showing up directly in patient harm data.
Wrong-site surgery is the category that tends to generate the most public outrage, and rightly so. 127 wrong surgery events in a single year, up 13% from the prior year, involving procedures performed on the wrong side of the body (56% of wrong-site cases), the wrong patient, or the wrong procedure entirely — these are errors that every accreditation body, every surgical checklist protocol, and every pre-operative “time-out” procedure was specifically designed to prevent. The Joint Commission’s own reporting notes that the contributing factors are not mysterious: failure to follow verification protocols, teams that rushed through or skipped required steps, and concerns raised by team members that were ignored before the wrong procedure began. That these events increased by 13% in a year when these protocols are well-established and widely mandated is not a knowledge problem. The Joint Commission’s own 2025 analysis states it explicitly: these are execution failures driven by fatigue, staffing shortages, and protocol non-enforcement.

Diagnostic errors are probably the most underdiscussed patient safety crisis in American medicine. The 795,000 Americans who die or become permanently disabled annually from misdiagnosis is a figure that dwarfs most other preventable harm categories — and yet it receives a fraction of the public and policy attention given to, say, surgical complications or hospital-acquired infections. AHRQ’s own director framed it plainly in a 2024 Patient Safety Awareness Week statement: “Most people will experience at least one diagnostic error in their lifetime, sometimes with devastating consequences.”
What makes the JAMA Internal Medicine 2024 study particularly valuable is its setting: academic medical centers, which are generally considered the most sophisticated and well-resourced institutions in American healthcare. Among patients who died or were transferred to an ICU in those settings, 23% had a missed or delayed diagnosis. If 23% of the most seriously ill patients in the country’s best hospitals are experiencing diagnostic errors, the rates at community hospitals and rural facilities are almost certainly higher. The “Big Three” categories — vascular events like stroke, serious infections like sepsis and meningitis, and cancers — account for roughly 300,000 of the 795,000 serious diagnostic harms annually. These are diseases where a missed diagnosis is not just unfortunate — it is often fatal. Stroke missed in an emergency department. Sepsis called “likely viral” and sent home. Lung cancer identified 18 months after the first concerning imaging.

The CDC’s 2024 HAI report — the most current federal data, covering calendar year 2024 and released January 29, 2026 — is genuinely mixed news. Most tracked infection categories improved compared to 2023, some meaningfully. C. difficile dropped 11%. CAUTI dropped 10%. CLABSI dropped 9%. All 50 states performed better than the 2015 national baseline on at least two infection types. That is real progress, and it reflects decades of infection control work, hand hygiene campaigns, catheter insertion protocols, and the infrastructure of the CDC’s National Healthcare Safety Network (NHSN). Progress is possible. The numbers prove it.
But the baseline context still makes for uncomfortable reading. 18,100 central line bloodstream infections still occur annually in US ICUs and general wards — even after a 9% drop. Each one of those is a patient who went into a hospital for care and developed a potentially fatal bloodstream infection from a line that was placed to help them. More than 1 million HAIs occur across the US healthcare system every year, costing $35.7 to $45 billion. The abdominal hysterectomy surgical site infection increase of 8% is the category going the wrong direction in 2024, and it stands out because every other tracked category improved. The HHS noted in its 2024 framework that HAI rates are “only now getting back to pre-pandemic levels” after significant losses during COVID-19 — meaning the progress of 2023 and 2024 is partly catching up from a setback, not building on a long-running improvement trend.

Medication errors are the most common type of medical error — and in many ways, the most documented. The FDA’s MedWatch program receives more than 2 million adverse event and medication error reports every year. The National Academy of Sciences’ 2006 estimate that medication errors harm at least 1.5 million Americans annually is still the most widely cited figure in clinical literature, and there is no strong evidence the situation has improved materially since then. The IOM’s 2007 estimate of one medication error per patient per day in hospital care has similarly held up as a rough order-of-magnitude benchmark.
The data on where errors originate is specific enough to be actionable. Over 53% of medication errors occur at the prescribing and ordering stage — meaning a physician or provider ordered the wrong drug, wrong dose, or wrong route before a pharmacist or nurse ever touched the prescription. IV medications have the highest error rate of any delivery route, at 48–53% in hospitals and long-term care. Children experience a medication error at home once every eight minutes in the US, mostly involving incorrect dosing by caregivers. Seniors face a disproportionate risk — elderly patients are hospitalized nearly twice as often as younger adults for medication-related problems, driven by polypharmacy, age-related pharmacokinetic changes, and the complexity of managing multiple chronic conditions simultaneously. Antibiotics are the drug class most commonly involved in medication-related harm (20% of events), followed by antipsychotics (19%), CNS medications (16%), and cardiovascular drugs (15%) — all categories used in high volumes across inpatient and outpatient settings.

The $56 million average among the top 50 malpractice verdicts in 2024 is a number that has gotten the attention of every insurer, hospital system, and physician in the country. It is a record. It was preceded by $48 million in 2023 and $32 million in 2022 — a straight-line upward trajectory that the nation’s largest physician-owned malpractice insurer called “alarming.” The Doctors Company’s September 2025 study found that combined economic and social inflation added $4 billion in losses to physician-focused malpractice insurers over the decade ending in 2024 — and that the frequency of high-dollar claims rebounded sharply in 2023 after a pandemic-era dip, with claims over $2 million now occurring at more than ten times the rate they did in 1990.
The diagnostic error category dominates malpractice litigation. In a 20-year study of closed malpractice claims published in Patient Safety in 2024, diagnostic errors accounted for 26.6% of all cases, and 39% of those cases resulted in the patient’s death. Failure to diagnose and delay in diagnosis were the two most common specific allegations — the same failure modes driving the 795,000 annual diagnostic error deaths and disabilities figure in the clinical literature. The connection is direct: the cases that generate the biggest jury verdicts and the cases that generate the most preventable deaths are largely the same cases. The 5% figure — that only approximately 5% of deaths from medical errors ever result in a malpractice payment — reflects both the difficulty of proving causation in complex medical cases and the reality that most families affected by medical error never pursue litigation.
