Increased risk for sleep disorders in burn patients: A 14-year nationwide, population-based cohort study
2020
Abstract Background Burn is a major trauma that causes physical and psychosocial impairments, leading to sleep disorders. However, the data about risks for sleep disorders in patients over 3 years following burn injury are limited. Aim To investigate the long-term risks for sleep disorders in patients after burn injury and identify the high-risk population. Methods A 14-year population-based cohort study was performed using data from the 2000–2013 Taiwan National Health Insurance Research Database (NHIRD) which was a valid representative sample of the total population. All diagnoses of medical records in NHIRD were made by physicians and coded according to the ICD-9-CM. Cases diagnosed with burns (ICD-9 CM: N-code 940-949 and E-code 890-899) were included. The control group (non-burn injury group) was comprised quadruple the number of cases matched by index date, sex and age. Results In 2000–2013, among the 10,289 burn patients included and followed-up after the index year, burn injury significantly increased the risks for sleep disorders (Hazard Ratio; HR = 1.36, p = 0.044), including insomnia (HR = 1.41, p = 0.036), sleep disturbance (HR = 2.39, p = 0.005) and sleep apnoea (HR = 1.38, p = 0.029). Compared with the control group, those who were women (HR = 1.73, p = 0.021), adolescents (HR = 5.45, p Conclusion Burn had long-term negative effects on sleep during both the first year of burn injury and the subsequent follow-up 14 years. It is important for physicians to long-term assess the sleep quality of burn patients regardless of the number of years after burn injury.
