Abstract:
According to epidemiological studies adverse drug events are one of the most frequently encountered complications during medical treatment, a leading cause of hospitalisation and frequent cause of death. However, medical malpractice claims due to medication errors seem to be relatively rare. Based on a retrospective multicentre study on medical malpractice cases with lethal outcome (n=4450), drug related cases (n=575) were further evaluated. In 50% of cases a causal connection between drug therapy and death could be ruled out already after autopsy. In 232 cases a causal connection between drug therapy and death could be approved (drug allergies, relative overdose, wrong application, mix-up of drugs and sepsis after injection abscess). However, within the legal context only in 70 cases a medication error was approved which was in 42 cases causal for death, in 28 not. Administration of contraindicated drugs, incorrect application and relative overdose in renal insufficiency are the prevalent mistakes. Concerning the frequency of ADE in epidemiological studies medication errors are underreported in all data sources on medical malpractice; this seems to be due to the fact that even doctors and attending physicians rarely recognize an ADE; furthermore approving the connection between drug effect and death is extremely difficult for the expert witness.
Insights
Medication errors causing death are underreported in medical malpractice claims. Even when adverse drug events (ADEs) are suspected, proving a causal link to death is legally challenging for physicians and expert witnesses.
Area of Science:
- Medical Law
- Pharmacovigilance
- Clinical Toxicology
Background:
- Adverse drug events (ADEs) are common and serious medical complications.
- Despite their frequency, medication errors leading to malpractice claims are infrequent.
- Lethal outcomes from drug-related issues present diagnostic and legal challenges.
Purpose of the Study:
- To evaluate the frequency and nature of medication errors in medical malpractice cases with lethal outcomes.
- To compare the incidence of ADEs in epidemiological studies with their recognition in legal malpractice claims.
- To identify prevalent types of medication errors and reasons for underreporting.
Main Methods:
- Retrospective multicenter study of 4450 medical malpractice cases with lethal outcomes.
- Focused analysis on 575 drug-related cases.
- Inclusion of autopsy findings and expert witness evaluations to establish causal connections.
Main Results:
- In 50% of drug-related cases, no causal link between drug therapy and death was found post-autopsy.
- A causal link was approved in 232 cases (e.g., drug allergies, overdose, wrong application).
- Legally, only 70 cases involved approved medication errors, with 42 deemed causal for death. Common errors included contraindicated drugs, incorrect application, and overdose in renal insufficiency.
Conclusions:
- Medication errors are significantly underreported in medical malpractice data compared to epidemiological ADE data.
- Physicians and expert witnesses face difficulties in recognizing ADEs and establishing a legal causal link to death.
- Legal recognition of medication errors as a cause of death is substantially lower than their actual occurrence.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
