Objectives: Rocking motion therapy has been shown to calm people with dementia but has never been investigated in delirious patients in the ICU. The aim of this clinical trial was to investigate the efficacy and safety of a rocking motion vs. nonrocking motion chair on the duration of delirium and intensity of agitation in ICU patients with delirium. We hypothesized that rocking motion therapy would increase the number of days alive without coma or delirium at 2 weeks of follow-up.

Design: This was a multicenter, investigator initiated, parallel-group randomized controlled trial.

Setting/patients: ICU patients 18 years or older with a positive delirium assessment.

Interventions: Participants were assigned to either a minimum of 20 minutes rocking motion therapy or a minimum of 20 minutes in the same chair without rocking motion therapy turned on daily.

Measurements and main results: The primary outcome was days alive without coma or delirium 2 weeks after randomization. We enrolled 149 patients; 73 were randomly assigned to rocking motion therapy and 76 to nonrocking motion therapy. Primary outcome data were available in 141 patients.

Conclusions: Among patients with delirium in the ICU, the use of rocking motion therapy did not lead to a statistically significantly greater number of days alive without coma or delirium at the 2 weeks of follow-up than nonrocking motion therapy.

Objectives: To explore associations between the physical, cognitive, and mental post-intensive care syndrome (PICS) health domains with changes in health-related quality of life (HRQoL) following ICU admission.

Design: A longitudinal prospective multicenter cohort study.

Setting/patients: Patients ( n = 4092) from seven Dutch ICUs.

Interventions: None.

Measurements and main results: At ICU admission, 3 and 12 months post-ICU, patients completed validated questionnaires regarding physical health problems, cognitive health problems, mental health problems, and HRQoL. Composite scores were created for the physical health domain (physical problems and fatigue) and mental health domain (anxiety, depression, and post-traumatic stress disorder). Adjusted multivariable linear regression analyses were performed, including covariables (e.g., patient characteristics, disease severity, pre-ICU HRQoL, etc.) to explore associations between the physical, cognitive, and mental health domains of PICS and changes in HRQoL at 3 and 12 months post-ICU. At 3 months ( n = 3368), physical health problems (β = -0.04 [95% CI, -0.06 to 0.02]; p < 0.001), cognitive health problems (β = -0.05 [95% CI, -0.09 to -0.02]; p < 0.001), and mental health problems (β = -0.08 [95% CI, -0.10 to -0.05]; p < 0.001) were negatively associated with changes in HRQoL. Also, at 12 months ( n = 2950), physical health problems (β = -0.06 [95% CI, -0.08 to -0.03]; p < 0.001), cognitive health problems (β = -0.04 [95% CI, -0.08 to -0.01]; p < 0.015), and mental health problems (β = -0.06 [95% CI, -0.08 to -0.03]; p < 0.001) were negatively associated with changes in HRQoL.

Conclusions: PICS symptoms in the physical, cognitive, and mental domains are all negatively associated with changes in HRQoL at 3 and 12 months post-ICU. At 3 months, PICS symptoms in the mental domain seem to have the largest negative associations. At 12 months, the associations of PICS in the mental and physical domains are the same. This implies that daily ICU care and follow-up care should focus on preventing and mitigating health problems across all three PICS domains to prevent a decrease in HRQoL.

Objectives: Diabetes mellitus has been associated with greater difficulty of tracheal intubation in the operating room. This relationship has not been examined for tracheal intubation of critically ill adults. We examined whether diabetes mellitus was independently associated with the time from induction of anesthesia to intubation of the trachea among critically ill adults.

Design: A secondary analysis of data from five randomized trials completed by the Pragmatic Critical Care Research Group (PCCRG).

Setting: Emergency departments (EDs) or ICUs at 11 centers across the United States that enrolled in randomized trials of a pre-intubation checklist, fluid bolus administration, bag-mask ventilation between induction and laryngoscopy, and intubation using a bougie vs. stylet.

Patients: Critically ill adults undergoing tracheal intubation with a laryngoscope in an ED or an ICU.

Interventions: None.

Measurements and main results: A total of 2654 patients were included in this analysis, of whom 638 (24.0%) had diabetes mellitus. The mean time from induction of anesthesia to intubation of the trachea was 169 seconds (sd, 137s). Complications occurred during intubation in 1007 patients (37.9%). Diabetes mellitus was not associated with the time from induction of anesthesia to intubation of the trachea (-4.4 s compared with nondiabetes; 95% CI, -17.2 to 8.3 s; p = 0.50). Use of a video vs. direct laryngoscope did not modify the association between diabetes mellitus and the time from induction to intubation (p for interaction = 0.064). Diabetes mellitus was not associated with the probability of successful intubation on the first attempt (85.6% vs. 84.3%; p = 0.46) or complications during intubation (39.8% vs. 37.4%; p = 0.52).

Conclusions: Among 2654 critically ill patients undergoing tracheal intubation in an ED or an ICU, diabetes mellitus was not independently associated with the time from induction to intubation, the probability of successful intubation on the first attempt, or the rate of complications during intubation.

Objectives: To summarize the delirium treatment trial literature, identify the unique challenges in delirium treatment trials, and formulate recommendations to address each in older adults.

Design: A 39-member interprofessional and international expert working group of clinicians (physicians, nurses, and pharmacists) and nonclinicians (biostatisticians, epidemiologists, and trial methodologists) was convened. Four expert panels were assembled to explore key subtopics (pharmacological/nonpharmacologic treatment, methodological challenges, and novel research designs).

Methods: To provide background and context, a review of delirium treatment randomized controlled trials (RCTs) published between 2003 and 2023 was conducted and evidence gaps were identified. The four panels addressed the identified subtopics. For each subtopic, research challenges were identified and recommendations to address each were proposed through virtual discussion before a live, full-day, and in-person conference. General agreement was reached for each proposed recommendation across the entire working group via moderated conference discussion. Recommendations were synthesized across panels and iteratively discussed through rounds of virtual meetings and draft reviews.

Results: We identified key evidence gaps through a systematic literature review, yielding 43 RCTs of delirium treatments. From this review, eight unique challenges for delirium treatment trials were identified, and recommendations to address each were made based on panel input. The recommendations start with design of interventions that consider the multifactorial nature of delirium, include both pharmacological and nonpharmacologic approaches, and target pathophysiologic pathways where possible. Selecting appropriate at-risk patients with moderate vulnerability to delirium may maximize effectiveness. Targeting patients with at least moderate delirium severity and duration will include those most likely to experience adverse outcomes. Delirium severity should be the primary outcome of choice; measurement of short- and long-term clinical outcomes will maximize clinical relevance. Finally, plans for handling informative censoring and missing data are key.

Conclusions: By addressing key delirium treatment challenges and research gaps, our recommendations may serve as a roadmap for advancing delirium treatment research in older adults.
