Medication errors remain one of the most persistent threats to patient safety, which can, in turn, be some of the most consequential from a malpractice perspective. In a health system where billions of prescriptions are filled each year, and medication use spans every setting, specialty, and stage of life, the opportunity for harm is constant. Medication-related harm can arise from prescribing, dispensing, administering, or monitoring failures, making medication safety a continuous process that depends on coordinated care.
Candello, a national MPL claims data collaborative, analyzed 66,617 MPL cases closed between 2014 and 2023 and found that medication-related errors were the primary allegation in 4,114 cases, accounting for 6% of the total. That share may seem modest at first glance, but the severity of these cases tells a different story. Medication allegations were more likely than other malpractice cases to involve death, and collectively they generated nearly $1 billion in gross incurred losses. For risk leaders and clinicians alike, the message is straightforward: medication breakdowns are common enough to demand constant attention and severe enough to warrant system-level prevention.
Clinical injury severity: Medication-related cases were more likely to involve fatal outcomes than cases without a medication allegation. Thirty-one percent involved death, compared with 22% of non-medication cases. Nearly half of all medication-related cases involved high-severity harm, underscoring how quickly these errors can move from a process lapse to a life-altering event.
Setting: Physician offices and clinics were the most frequent setting for medication allegations, reinforcing a broader patient safety concern: much of medication risk lives outside the hospital.
This finding aligns with published research showing that the most common adverse event in outpatient settings are drug-related and often driven by workflow vulnerabilities, communication gaps, and increased patient responsibility for day-to-day medication management. Yet the most devastating outcomes in this case set occurred in inpatient units, where 45% of alleged events resulted in death, compared with 28% in emergency settings and 27% in physician offices.
Primary responsible services: No discipline is insulated from medication risk, but the distribution of cases shows where exposure is especially concentrated. Internal medicine and family medicine each accounted for 13% of medication-related cases, followed by nursing at 11%, surgery at 6%, and psychiatry at 5%. Medication-related risk is not confined to a few high-volume specialties. Any service that prescribes, dispenses, administers, or monitors medications shares responsibility for medication safety and should consider it a central element of its risk profile.
At What Point Does it Go Wrong?
Medication errors can occur anywhere along the medication care continuum, from the initial decision to order a drug through dispensing, administration, and long-term monitoring. In malpractice cases, however, one step appears especially vulnerable: management after the medication reaches the patient. Across all medication-related cases, the average total incurred was $242,000, and the data indicate that improper medication management carried the greatest clinical and financial exposure. That makes intuitive sense. The most preventable failures are often not isolated prescribing mistakes, but breakdowns in reconciliation, follow-up, response to warning signs, and coordination during transitions of care.
Which Medications Present the Most Risk?
The cases also show that several drug classes repeatedly surface in high-risk events. Analgesics and narcotics accounted for 18% of medication-related cases, followed by anticoagulants at 15% and antibiotics at 13%. Anticoagulants carried the greatest severity burden, with 74% of related cases involving high-severity injury or death. National safety data similarly identify anticoagulants and antibiotics among the medication classes most frequently associated with serious adverse drug events, underscoring the importance of careful monitoring, patient education, and safe transitions of care.
What makes medication malpractice cases especially challenging is that they often sit at the intersection of clear-cut error and complicated clinical reality. Some claims are straightforward, while others involve nonadherence, polypharmacy, comorbidities, or fragmented care. Yet across both types of cases, the same vulnerabilities recur: incomplete histories, weak reconciliation practices, alert fatigue, poor patient education, and delayed recognition of adverse effects.
In other words, medication liability is rarely just about the medication itself, but rather how reliably the care team manages information, anticipates risk, and responds when the patient’s course changes.
The good news is that many of the most effective safeguards are already well known. The challenge is applying them consistently in busy, fragmented care environments. For organizations seeking to reduce medication-related harm and defend against avoidable malpractice exposure, several strategies stand out.
1. Utilize Clinical Decision Support Systems (CDSS) for Medication Management
First, use clinical decision support well. According to the Patient Safety Network, tools such as computerized prescribing support can reduce errors by flagging dosing issues, contraindications, and drug interactions. But technology is not self-executing. If alerts are routinely overridden without clear rationale, organizations may simply replace one form of risk with another. Thoughtful configuration, clinician training, and documentation of override decisions all matter.
2. Pharmacists in Clinical Rounds
Second, bring pharmacists into the workflow wherever possible. Medication management improves when pharmacotherapy expertise is embedded in clinical decision-making, particularly for complex patients and high-risk drugs. Pharmacist participation in rounds, transitions, and medication review can help identify discrepancies, improve reconciliation, and catch emerging issues before they become injuries.
3. Focus on Best Practices in Ambulatory Settings
Third, focus aggressively on ambulatory medication safety. Because so many medication allegations originate in offices and clinics, prevention efforts cannot stop at hospital walls. Key ambulatory safeguards include medication reconciliation, patient education, e-prescribing, and reliable follow-up processes to ensure therapies remain appropriate over time.
4. Improve Patient Education
Finally, strengthen the human side of medication safety. Patients who do not understand what they are taking, why they are taking it, what side effects to watch for, or when to seek help are more vulnerable to harm. The CDC emphasizes practical medication safety steps such as maintaining an up-to-date medication list, following directions carefully, and obtaining needed monitoring. In malpractice prevention terms, that translates to better education, better documentation, and better systems for closing the loop when warning signs emerge.
A decade of MPL cases suggests that medication risk is driven less by isolated prescribing errors than by failures in communication, monitoring, and follow-up. Organizations that treat medication management as a continuous, team-based responsibility, which is supported by technology, strengthened by pharmacist involvement, and sustained through reliable follow-up, will be best positioned to reduce both patient harm and malpractice exposure.
