Delirium in the United States: Results From the 2023 Cross-Sectional World Delirium Awareness Day Prevalence Study.

BACKGROUND: Delirium is an acute brain dysfunction associated with an increased risk of mortality and future dementia. OBJECTIVES: To describe the prevalence of clinically documented delirium in the United States on World Delirium Awareness Day 2023. METHODS: This is a sub-analysis of a prospective, cross-sectional, online, international survey. All health care settings were eligible, with the exception of operating rooms and outpatient clinics. Health care clinicians, administrators, and researchers completed the survey. The primary outcome was the prevalence of clinically documented delirium at 8:00 a.m. and 8:00 p.m. on March 15, 2023. Secondary outcomes were related to health care delivery. Descriptive statistics are reported. Differences between unit types (non-intensive care unit vs intensive care unit) were examined for all outcomes. RESULTS: Ninety-one hospital units reported on 1318/1213 patients. The prevalence of clinically documented delirium was 16.4% (n = 216/1318) at 8:00 a.m. and 17.9% (n = 217/1213) at 8:00 p.m. (P = 0.316) and significantly differed between age groups, reported discipline, unit, and hospital types. Significant differences were identified between non-intensive care unit and intensive care unit settings in the use of delirium-related protocols, nonpharmacologic and pharmacologic management, educational processes, and barriers to evidence-based delirium care. CONCLUSIONS: To our knowledge, this is the first epidemiologic survey of clinically documented delirium across two time points in the United States. Delirium remains a significant burden and challenge for health care systems. The high percentage of units using delirium management protocols suggests administrator and clinician awareness of evidence-based strategies for its detection and mitigation. We provide recommendations for future studies and quality improvement projects to improve clinical recognition and management of delirium.

COVID-19 and the Impact on Delirium Care of Hospitalized Older Adults: A Qualitative Study.

BACKGROUND: Older adult patients with COVID-19 and delirium experience higher rates of adverse outcomes. Early recognition of at-risk patients and implementation of management strategies improve outcomes, though understanding barriers to acute care nurses implementing these strategies is limited. PURPOSE: This study's purpose was to understand the experiences of acute care nurses providing care to older adults with COVID-19 and delirium. Experiences explored included assessment, nursing management interventions, and barriers to care. METHODS: Purposive sampling to recruit nurses for semistructured focus groups was performed, and thematic analysis was generated by 4 members of the research team. RESULTS: Twenty-one nurses participated in focus groups. Thematic analysis revealed themes of increased patient social isolation, barriers to delirium assessment and prevention, increased staff demands, and stressful work environments. CONCLUSION: Rich findings reveal the profound impact of the pandemic on assessment for delirium and implementation of strategies for prevention and management in older adult patients.

Implementing a Delirium Risk Stratification Tool and Rounds to Identify and Prevent Delirium in Hospitalized Older Adults.

BACKGROUND: Up to 40% of delirium cases are preventable, and early identification is key to improve patient outcomes. PURPOSE: To implement and evaluate a multidisciplinary delirium intervention program. INTERVENTION: The delirium intervention program targeted patients at high risk for delirium and included patient and nurse education, risk stratification, multidisciplinary rounds, a nonpharmacological intervention bundle, and a treatment order set. RESULTS: After implementation, there was a reduction in length of stay of 6.3 days ( P = .01), a 24% decrease in disposition to a skilled nursing facility ( P = .05), and increased detection of delirium by nurses. CONCLUSION: Positive patient outcomes were achieved by employing a multifactorial approach for delirium identification, prevention, and management. The components of this quality improvement project provide guidance to hospitals seeking to develop a delirium intervention program.
