Improving delirium care in the intensive care unit: the design of a pragmatic study.

ABSTRACT: Delirium prevalence in the intensive care unit (ICU) is high. Numerous psychotropic agents are used to manage delirium in the ICU with limited data regarding their efficacy or harms.This is a randomized controlled trial of 428 patients aged 18 and older suffering from delirium and admitted to the ICU of Wishard Memorial Hospital in Indianapolis. Subjects assigned to the intervention group will receive a multicomponent pharmacological management protocol for delirium (PMD) and those assigned to the control group will receive no change in their usual ICU care. The primary outcomes of the trial are (1) delirium severity as measured by the Delirium Rating Scale revised-98 (DRS-R-98) and (2) delirium duration as determined by the Confusion Assessment Method for the ICU (CAM-ICU). The PMD protocol targets the three neurotransmitter systems thought to be compromised in delirious patients: dopamine, acetylcholine, and gamma-aminobutyric acid. The PMD protocol will target the reduction of anticholinergic medications and benzodiazepines, and introduce a low-dose of haloperidol at 0.5-1 mg for 7 days. The protocol will be delivered by a combination of computer (artificial intelligence) and pharmacist (human intelligence) decision support system to increase adherence to the PMD protocol.The proposed study will evaluate the content and the delivery process of a multicomponent pharmacological management program for delirium in the ICU.ClinicalTrials.gov: NCT00842608.

Project description:BACKGROUND/OBJECTIVE:Delirium in the intensive care units (ICUs) is prevalent, with both delirium duration and delirium severity associated with adverse outcomes. We designed a pragmatic trial to test the efficacy of a pharmacological management of delirium (PMD) bundle in improving delirium/coma-free days and reducing delirium severity among ICU patients. DESIGN:A randomized pragmatic clinical trial. SETTING:Medical, surgical, and progressive ICUs of three tertiary care hospitals. PARTICIPANTS:A total of 351 critically ill patients. INTERVENTION:A multicomponent PMD bundle consisting of reducing the exposure to 20 definite anticholinergic medications and benzodiazepines and prescribing low-dose haloperidol. MEASUREMENTS:The primary outcomes were delirium/coma-free days, measured through the Richmond Agitation-Sedation Scale and the Confusion Assessment Method for the ICU (CAM-ICU), and delirium severity, measured through Delirium Rating Scale-Revised-98 and the CAM-ICU-7. Secondary outcomes were in-hospital and posthospital discharge 30-day mortality, ICU and hospital lengths of stay, and delirium-related hospital complications. RESULTS:We randomized 351 critically ill delirious patients (mean age = 59.3 years [SD = 16.9 years]; 52% female, 42% African Americans) to receive the PMD bundle or usual care. There were no significant differences in median delirium/coma-free days at day 8 (PMD vs usual care = 4 [interquartile range {IQR} = 2-7] days vs 5 [IQR = 1-7] days; P = .888) or at day 30 (PMD vs usual care = 26 [IQR 19-29] days vs 26 [IQR, 14-29] days; P = .991). There were no significant differences for decrease in delirium severity at day 8, but at hospital discharge, the intervention group showed a greater reduction in delirium severity (mean decrease in CAM-ICU-7 score for PMD vs usual care = 3.2 [SD = 3.3] vs 2.5 [SD = 3.2]; P = .046). No differences were observed between groups for ICU and hospital lengths of stay, mortality, and delirium-related hospital complications. Similar results were observed when analyses were limited to patients 65 years or older and 75 years or older. CONCLUSION AND RELEVANCE:Implementing the PMD bundle in the ICU did not reduce delirium duration or severity among critically ill patients.

Project description:BACKGROUND:Accurate prediction of delirium in the intensive care unit (ICU) may facilitate efficient use of early preventive strategies and stratification of ICU patients by delirium risk in clinical research, but the optimal delirium prediction model to use is unclear. We compared the predictive performance and user convenience of the prediction model for delirium (PRE-DELIRIC) and early prediction model for delirium (E-PRE-DELIRIC) in ICU patients and determined the value of a two-stage calculation. METHODS:This 7-country, 11-hospital, prospective cohort study evaluated consecutive adults admitted to the ICU who could be reliably assessed for delirium using the Confusion Assessment Method-ICU or the Intensive Care Delirium Screening Checklist. The predictive performance of the models was measured using the area under the receiver operating characteristic curve. Calibration was assessed graphically. A physician questionnaire evaluated user convenience. For the two-stage calculation we used E-PRE-DELIRIC immediately after ICU admission and updated the prediction using PRE-DELIRIC after 24 h. RESULTS:In total 2178 patients were included. The area under the receiver operating characteristic curve was significantly greater for PRE-DELIRIC (0.74 (95% confidence interval 0.71-0.76)) compared to E-PRE-DELIRIC (0.68 (95% confidence interval 0.66-0.71)) (z score of -?2.73 (p?<?0.01)). Both models were well-calibrated. The sensitivity improved when using the two-stage calculation in low-risk patients. Compared to PRE-DELIRIC, ICU physicians (n?=?68) rated the E-PRE-DELIRIC model more feasible. CONCLUSIONS:While both ICU delirium prediction models have moderate-to-good performance, the PRE-DELIRIC model predicts delirium better. However, ICU physicians rated the user convenience of E-PRE-DELIRIC superior to PRE-DELIRIC. In low-risk patients the delirium prediction further improves after an update with the PRE-DELIRIC model after 24 h. TRIAL REGISTRATION:ClinicalTrials.gov, NCT02518646 . Registered on 21 July 2015.

Project description:PurposeTo systematically review and evaluate the effectiveness of interventions in order to improve the safety and efficiency of patient handover between intensive care unit (ICU) and general ward healthcare professionals at ICU discharge.MethodsPubMed, CINAHL, PsycINFO, EMBASE, Web of Science, and the Cochrane Library were searched for intervention studies with the aim to improve clinical handover between ICU and general ward healthcare professionals that had been published up to and including June 2013. The methods for article inclusion and data analysis were pre-specified and aligned with recommendations outlined in the PRISMA guideline. Two reviewers independently extracted data (study purpose, setting, population, method of sampling, sample size, intervention characteristics, outcome, and implementation activities) and assessed the quality of the included studies.ResultsFrom the 6,591 citations initially extracted from the six databases, we included 11 studies in this review. Of these, six (55 %) reported statistically significant effects. Effective interventions included liaison nurses to improve communication and coordination of care and forms to facilitate timely, complete and accurate handover information. Effective interventions resulted in improved continuity of care (e.g., reduced discharge delay) and in reduced adverse events. Inconsistent effects were observed for use of care, namely, reduction of length of stay versus increase of readmissions to higher care. No statistically significant effects were found in the reduction of mortality. The overall methodological quality of the 11 studies reviewed was relatively low, with an average score of 4.5 out of 11 points.ConclusionsThis review shows that liaison nurses and handover forms are promising interventions to improve the quality of patient handover between the ICU and general ward. More robust evidence is needed on the effectiveness of interventions aiming to improve ICU handover and supportive implementation strategies.
