Background: A vast amount of literature is available on the burden of acute ischemic stroke (AIS). Yet, most information on AIS burden does not stratify by stroke severity, and the inclusion of mild strokes (National Institute of Health Stroke Scale < 5) might obscure the true impact of moderate-to-severe AIS. Therefore, it is important to understand the literature as it pertains to the epidemiological, clinical, humanistic, and economic burden of moderate-to-severe AIS from a global perspective. Methods: A systematic literature review (SLR) was conducted, including articles published between January 2015 and June 2023. The clinical burden search focused on patients with moderate or severe AIS. Due to the paucity of evidence, the humanistic and economic burdens were evaluated based on overall AIS studies. Abstract and full-text screening were conducted by 2 reviewers, with data extraction completed by 1 reviewer. In all, 136 studies were included in the SLR. Results: AIS caused a substantial burden for patients and the healthcare system. The clinical burden of AIS (specifically severe AIS) resulted in high mortality and worse functional outcomes across multiple demographics (female sex, older age, and patients with comorbidities). The economic burden of overall AIS was substantial, with inpatient costs as the primary driver (a mean or median stay of 7 days). The highest inpatient costs were reported in South Korea ($45,180) and the United States ($38,470). Conclusions: The review highlighted the huge burden of moderate-to-severe AIS, with patients experiencing worse outcomes with increased stroke severity. Further focus is needed on outcomes relating to moderate-to-severe AIS to fully understand the burden of stroke in this patient population.

Introduction: Delirium is a common, severe neuropsychiatric syndrome in hospitalised older adults. We evaluated use of validated delirium assessment tools, adherence to national guidelines and prevalence and management of delirium across Scotland, identifying barriers to effective care. Methods: Secondary analysis of national survey data, collected by participating clinicians on World Delirium Awareness Day (15 March 2023). Results: Among 120 responses (3,257 patients), the 4AT was the most frequently used assessment tool (75%), while 14% of units reported using clinical judgement alone. The delirium assessment rate was 74%, with a prevalence of 22% at 8 am. Management protocols varied, with frequent routine non-pharmacological interventions including pain management (88%), hydration (87%) and open family visiting (80%). Barriers to delirium care included insufficient staffing and training. Conclusion: While many hospital settings follow national delirium guidelines, some still rely on clinical judgement for assessment, with variability in management protocols and practices. We have highlighted key barriers to effective delirium care in Scotland.
