Epilepsy Raises Risk of Unnatural Death

Article excerpt

PEOPLE WITH EPILEPSY were about three times more likely to die from unnatural causes and five times more likely to die from unintentional medication poisoning than controls in a large study.

Opioid and psychotropic drugs were the main sources of poisoning deaths, said Hayley C. Gorton, PhD, of the University of Manchester (England) and her associates. Epilepsy also was associated with a twofold increase in risk of suicide. Providers should counsel patients with epilepsy about unintentional injuries, exercise caution when prescribing opioids, and monitor patients closely for suicidal thoughts, ideation, and behavior, the researchers wrote online April 9 in JAMA Neurology.

The study included 58,729 individuals with epilepsy and nearly 1.2 million controls matched by age, sex, and location. Data sources included the Clinical Practice Research Datalink in England and the Secure

Anonymised Information Linkage Databank in Wales. The researchers identified unnatural deaths by querying relevant codes from the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision. The study spanned 1998-2014, with typically 4-8 years of follow-up.

Epilepsy was associated with a significantly increased risk of death from any unnatural cause (hazard ratio, 4 Continued from previous page 2.8; 95% confidence interval, 2.4-3.3), from accidental medication poisoning (HR, 5.0; 95% Cl, 3.2-7.7), and from suicide (HR, 2.2; 95% Cl, 1.5-3.1).

Opioids were the most common cause of death from medication poisoning (56%), followed by psychotropic drugs (32%), Dr. Gorton and her associates reported. Antiepileptic drugs were responsible for only about 10% of iatrogenic deaths.
