OBJECTIVE: The objective of this study was to investigate the impact and prevalence of sleep-wake disturbances among adult patients admitted for inpatient acquired brain injury rehabilitation.
METHOD: This was a retrospective cohort study involving all adults admitted for inpatient ABI neurocognitive rehabilitation at UHN-Toronto Rehabilitation Institute over a 12-month period (n = 165). The primary endpoint of the study was the comparison of functional independent measure efficiency and hospital length of stay between patients reporting sleep disturbance (e.g. increased sleep latency, obstructive sleep apnea [OSA], sleep maintenance insomnia) versus those with normal sleep.
RESULTS: We found that more than half (58.2%) of patients experienced sleep disturbance based on a combination of self-report and clinical documentation. The most common sleep disturbance was increased sleep onset latency (28.5%), followed by mixed sleep onset/maintenance insomnia (14.5%) and obstructive sleep apnea (8.5%). Notably, OSA was associated with longer length of hospital stay and reduced functional independence measure (FIM) efficiency in the cognitive domain after accounting for age and number of medical comorbidities. IMPLICATIONS: The results of this investigation underscore the importance of screening patients with brain injury for sleep disturbances due to its high prevalence and impact on rehabilitation efficiency.
