AbstractNarcolepsy is a rare brain disorder characterized by excessive daytime sleepiness (EDS), cataplexy, hypnagogic hallucinations, and sleep paralysis. Stimulants have been used to relieve the symptoms of EDS. Narcolepsy symptoms may pose a risk to burn injury. The study aimed to investigate the risk of burn injury in narcolepsy patients and to examine the relationship between the use of stimulants and the risk of burn injury. In all, 507 narcolepsy patients and 504 controls matched by gender, age, index year, and Charlson Comorbidity Index (CCI) score were enrolled between 1998 and 2012, then followed until the end of 2013 using Taiwan's National Health Insurance Research Database. During the follow-up period, participants who developed burn injury were identified. Cox regression analysis was used to calculate the hazard ratio (HR) with 95% confidence interval (CI) of the burn incidence rate between narcolepsy patients and unaffected controls. Narcolepsy patients had a significantly increased risk of burn injury compared to unaffected controls (5.37 versus 2.69 per 1,000 person-years, HR: 2.04, 95% CI: 1.13-3.67) after adjusting for gender, age, CCI score, urbanization degree, and duration of stimulants use. Also, the use of stimulants in narcolepsy patients was associated with a lower incidence rate of developing burn injury, but the risk estimate was not statistically significant after adjusting for the above-mentioned variables. This study shows narcolepsy patients have an increased risk of burn injury and the use of stimulants may reduce the burn incidence rate, providing a reference for developing prevention interventions.© American Burn Association 2020.
