Implementing a Multicomponent Intervention to Prevent Delirium Among Critically Ill Patients

Impact of Living Arrangements on Delirium in Older ED Patients

Background: The purpose of this study is to assess how the socio-family demographic status of patients is related to the onset of delirium in a large cohort of older adults aged ≥65 years evaluated in the emergency department (ED) using a comprehensive geriatric assessment (CGA). Methods: This is a cross-sectional, observational, retrospective study conducted in the ED of a teaching hospital. We enrolled 2770 geriatric patients admitted to the ED from January 2019 to December 2023 and evaluated them using CGA. Clinical variables assessed in the ED were evaluated for associations with delirium onset and in-hospital mortality. Results: Delirium was statistically related to frailty statuses as measured via the Clinical Frailty Scale (CFS) (OR 1.47 [1.39-1.56]; p < 0.001). The occurrence of delirium was also associated with living arrangements: "living with other relatives" condition (OR 1.43 [1.12-1.83]; p = 0.004) and residence in a nursing home (OR 1.72 [1.30-2.31]; p < 0.001). In addition, compared to patients in emergency conditions (NEWS > 5), it emerges that patients with better clinical stability have a lower risk of developing delirium (NEWS 3-5 OR 0.604 [0.48-0.75]; p < 0.001-NEWS < 3 OR 0.42 [0.34-0.53]; p < 0.001). In-hospital mortality was associated with age, male sex, frailty status, clinical instability, and the onset of delirium in the ED. Conclusions: Delirium is a multifactorial and acute syndrome representing a negative prognostic factor of in-hospital mortality, especially in elderly patients. Independent of the clinical condition, the patient's living arrangement could be of relevance to the onset of delirium in the ED. Early comprehensive geriatric assessments in the ED could allow the early detection of all predisposing risk factors, resulting in the timely implementation of supportive strategies to prevent the onset of delirium in EDs.

Preventive effects of early mobilisation on delirium incidence in critically ill patients: systematic review and meta-analysis

OBJECTIVE

To evaluate whether early mobilisation can reduce the incidence of delirium in critically ill patients and to assess the methodological quality of published studies.

METHODS

Three electronic databases, PubMed, Embase and the Cochrane Library, were searched for relevant studies published up to 2 March 2024. Articles were screened independently by two reviewers, based on inclusion and exclusion criteria, and a meta-analysis was performed using RevMan 5.3 software with a random-effects model.

RESULTS

A total of 18 studies (intervention group: 1794 participants, control group: 2129 participants) were included in the systematic review, with 18 studies included in the meta-analysis. Early mobilisation was found to reduce the risk of delirium in critically ill populations, with a pooled odds ratio of 0.65 (95% confidence interval [CI] 0.49-0.86; P = 0.003; I2 = 59%). Additionally, two studies found that early mobilisation did not change the duration of delirium in critically ill populations, with a pooled mean difference of -1.53 (95% CI -3.48 to 0.41; P = 0.12; I2 = 37%). Subgroup analysis revealed that early mobilisation maintained its preventive effect on delirium in the before/after intervention studies, studies published before 2018 and studies with a moderate methodological rating.

CONCLUSION

As a nonpharmacological intervention, early mobilisation may help reduce the risk of delirium and shorten its duration in critically ill patients compared with standard treatment and may potentially become a novel strategy for delirium prevention in future intensive care unit settings.

Exploring Cognitive Stimulation as a Therapy for the Prevention of Delirium in a Hospital Setting: A Narrative Review

Delirium is a highly prevalent and costly neuropsychiatric condition that affects up to 87% of critically ill hospitalized patients. It impacts various cognitive domains, including attention, memory, perception, and motor functions, with symptoms such as behavioral changes, hallucinations, slurred speech, visual impairments, and fatigue. Non-pharmacological interventions have been shown to reduce the incidence and duration of delirium, with strategies like reality orientation, cognitive stimulation, family support, and physical support. However, the scalability of these interventions in hospital settings is limited by resource constraints, low patient engagement, and the complexity of delivery. Digital technology-based cognitive stimulation offers a potential solution to these barriers, though evidence supporting its effectiveness is currently insufficient. This narrative literature review explores both traditional and novel digital technology-based cognitive stimulation techniques for the prevention and management of delirium in acute hospital settings.

Pain management interventions of the non-communicating patient in intensive care: What works for whom and why? A rapid realist review

AIM

The utility and uptake of pain management interventions across intensive care settings is inconsistent. A rapid realist review was conducted to synthesise the evidence for the purpose of theory building and refinement.

DESIGN

A five-step iterative process was employed to develop project scope/ research questions, collate evidence, appraise literature, synthesise evidence and interpret information from data sources.

METHODS

Realist synthesis method was employed to systematically review literature for developing a programme theory.

DATA SOURCES

Initial searches were undertaken in three electronic databases: MEDLINE, CINHAL and OVID. The review was supplemented with key articles from bibliographic search of identified articles. The first 200 hits from Google Scholar were screened.

RESULTS

Three action-oriented themes emerged as integral to successful implementation of pain management interventions. These included health facility actions, unit/team leader actions and individual nurses' actions.

CONCLUSION

Pain assessment interventions are influenced by a constellation of factors which trigger mechanisms yielding effective implementation outcomes.

IMPLICATIONS

The results have implications on policy makers, health organisations, nursing teams and nurses concerned with optimising the successful implementation of pain management interventions.

IMPACT

The review enabled formation of a programme theory concerned with explaining how to effectively implement pain management interventions in intensive care.

REPORTING METHOD

This review was informed by RAMESES publication standards for realist synthesis.

PUBLIC CONTRIBUTION

No patient or public contribution. The study protocol was registered in Open Science Framework. 10.17605/OSF.IO/J7AEZ.

Clinical Impact of the Implementation Strategies Used to Apply the 2013 Pain, Agitation/Sedation, Delirium or 2018 Pain, Agitation/Sedation, Delirium, Immobility, Sleep Disruption Guideline Recommendations: A Systematic Review and Meta-Analysis

OBJECTIVES

To summarize the effectiveness of implementation strategies for ICU execution of recommendations from the 2013 Pain, Agitation/Sedation, Delirium (PAD) or 2018 PAD, Immobility, Sleep Disruption (PADIS) guidelines.

DATA SOURCES

PubMed, CINAHL, Scopus, and Web of Science were searched from January 2012 to August 2023. The protocol was registered with PROSPERO (CRD42020175268).

STUDY SELECTION

Articles were included if: 1) design was randomized or cohort, 2) adult population evaluated, 3) employed recommendations from greater than or equal to two PAD/PADIS domains, and 4) evaluated greater than or equal to 1 of the following outcome(s): short-term mortality, delirium occurrence, mechanical ventilation (MV) duration, or ICU length of stay (LOS).

DATA EXTRACTION

Two authors independently reviewed articles for eligibility, number of PAD/PADIS domains, quality according to National Heart, Lung, and Blood Institute assessment tools, implementation strategy use (including Assess, prevent, and manage pain; Both SAT and SBT; Choice of analgesia and sedation; Delirium: assess, prevent, and manage; Early mobility and exercise; Family engagement and empowerment [ABCDEF] bundle) by Cochrane Effective Practice and Organization of Care (EPOC) category, and clinical outcomes. Certainty of evidence was assessed using Grading of Recommendations Assessment, Development, and Evaluation.

DATA SYNTHESIS

Among the 25 of 243 (10.3%) full-text articles included ( n = 23,215 patients), risk of bias was high in 13 (52%). Most studies were cohort ( n = 22, 88%). A median of 5 (interquartile range [IQR] 4-7) EPOC strategies were used to implement recommendations from two (IQR 2-3) PAD/PADIS domains. Cohort and randomized studies were pooled separately. In the cohort studies, use of EPOC strategies was not associated with a change in mortality (risk ratio [RR] 1.01; 95% CI, 0.9-1.12), or delirium (RR 0.92; 95% CI, 0.82-1.03), but was associated with a reduction in MV duration (weighted mean difference [WMD] -0.84 d; 95% CI, -1.25 to -0.43) and ICU LOS (WMD -0.77 d; 95% CI, -1.51 to 0.04). For randomized studies, EPOC strategy use was associated with reduced mortality and MV duration but not delirium or ICU LOS.

CONCLUSIONS

Using multiple implementation strategies to adopt PAD/PADIS guideline recommendations may reduce mortality, duration of MV, and ICU LOS. Further prospective, controlled studies are needed to identify the most effective strategies to implement PAD/PADIS recommendations.

The Impact of Non-Pharmacological Interventions on Delirium in Neurological Intensive Care Unit Patients: A Single-Center Interrupted Time Series Trial

Background: Delirium is a pathobiological brain process that is frequently observed in Intensive Care Unit (ICU) patients, and is associated with longer hospitalization as well as long-term cognitive impairment. In neurological ICU patients, delirium may be more treatment-resistant due to the initial brain injury. This study examined the effects of a multicomponent non-pharmacological nursing intervention program on delirium in neurological ICU patients. Methods: A single-center interrupted time series trial was conducted in adult neurological ICU patients at high risk for developing delirium who were non-delirious at admission. A multicomponent nursing intervention program focusing on modifiable risk factors for delirium, including the optimalization of vision, hearing, orientation and cognition, sleep and mobilization, was implemented as the standard of care, and its effects were studied. The primary outcome was the number of delirium-free and coma-free days alive at 28 days after ICU admission. The secondary outcomes included delirium incidence and duration, ICU and hospital length-of-stay and duration of mechanical ventilation. Results: Of 289 eligible patients admitted to the ICU, 130 patients were included, with a mean age of 68 ± 11 years, a mean APACHE-IV score of 79 ± 25 and a median predicted delirium risk (E-PRE-DELIRIC) score of 42 [IQR 38-50]). Of these, 73 were included in the intervention period and 57 in the control period. The median delirium- and coma-free days alive were 15 days [IQR 0-26] in the intervention group and 10 days [IQR 0-24] in the control group (level change -0.48 days, 95% confidence interval (95%CI) -7 to 6 days, p = 0.87; slope change -0.95 days, 95%CI -2.41 to 0.52 days, p = 0.18). Conclusions: In neurological ICU patients, our multicomponent non-pharmacological nursing intervention program did not change the number of delirium-free and coma-free days alive after 28 days.

Effects of non-pharmacologic prevention on delirium in critically ill patients: A network meta-analysis

BACKGROUND

Delirium is a common complication among patients in the intensive care unit (ICU). It is important to prevent the occurrence of delirium in critically ill patients.

AIM

This review aimed to evaluate the efficacy of non-pharmacological interventions and determine what combination of these is effective in preventing delirium among Intensive Care Unit patients.

STUDY DESIGN

A systematic review and meta-analysis. This review follows the guidelines of the Preferred Reporting Items for Systematic reviews and Meta Analysis statements for Network Meta-Analysis (PRISMA-NMA). Data sources included the Cumulative Index to Nursing & Allied Health Literature., MEDLINE, and Cochrane library databases. The integrated data were investigated with odds ratio (OR) and 95% confidence interval (95% CI), using the random-effects Mantel-Haenszel model. Data were considered significant when p < 0.05. Furthermore, to reveal what combination of care is effective, we performed a network meta-analysis estimated OR, 95% CI.

RESULTS

We identified three randomized controlled trials and eight controlled before-after trials (11 in total, with 2549 participants). The pooled data from 11 trials of multicomponent intervention had a significant effect on delirium prevention (OR 0.58, 95% CI 0.44-0.76, p < 0.001). As a result of network meta-analysis, two bundles were effective compared to the control group in reducing the incidence of delirium: a) the combination of sleep promotion (SP), cognitive stimulation (CS), early mobilization (EM), pain control (PC), and assessment (AS) (OR 0.47, 95% CI 0.35-0.64, p < 0.002), and b) the combination of SP and CS (OR 0.46, 95% CI 0.28-0.75, p < 0.001).

CONCLUSION

This study revealed that non-pharmacological interventions, particularly multicomponent interventions, helped to prevent delirium in critically ill patients. In the network meta-analysis, the most effective care combination for reducing incidence of delirium was found to be multicomponent intervention, which comprises SP-CS-EM-PC-AS, and SP-CS.

RELEVANCE TO CLINICAL PRACTICE

These findings reveal an efficient combination of multicomponent interventions for preventing delirium, which may be a very important prerequisite in planning care programs in the future.

The effects of a sensory stimulation intervention for preventing delirium in a surgical intensive care unit: A randomized controlled trial

BACKGROUND

Despite extensive efforts and advances in developing and fostering evidence-based delirium prevention interventions, the incidence of delirium remains high in hospitalized patients. Evidence suggests that sensory stimulation is a core component in interventions to prevent delirium among critically ill patients. However, its impact on the occurrence and outcomes of delirium is poorly understood.

AIM

To evaluate the effects of a sensory stimulation intervention on preventing delirium in a surgical intensive care unit (ICU).

STUDY DESIGN

A prospective, assessor-blind, parallel-group randomized controlled trial. Adult patients were recruited from a surgical ICU of one tertiary hospital in Guangzhou, China. Participants in the intervention group received a daily 30-min auditory and visual stimulation session for a week, taking into consideration the participants' predefined condition and intervention protocol. The primary outcomes were delirium incidence and delirium-free days, and the secondary outcomes were delirium duration, severity and the first occurrence of delirium. Demographic and clinical data were collected at recruitment, and delirium was assessed three times a day for seven consecutive days using Confusion Assessment-ICU.

RESULTS

One hundred and fifty-two participants were randomly assigned to intervention or control groups. For primary outcomes, there were fewer patients with delirium in the intervention group than in the control group (10 vs. 19, risk ratio = 0.53), although statistical significance was not reached. The result showed that there were longer delirium-free days among participants in the intervention group than in the control group (3.66 vs. 2.84, p = .019). For secondary outcomes, the intervention could significantly reduce delirium duration (1.70 ± 0.82 vs. 4.53 ± 2.74 days, p = .004) and delirium severity (3.70 ± 1.25 vs. 5.68 ± 1.57, p = .002). The Kaplan-Meier curve showed the intervention group had a significantly delayed first occurrence of delirium compared with the control group (p = .043).

CONCLUSIONS

The study did not provide significant evidence to support that sensory stimulation could reduce the incidence of delirium, but significant difference on delirium-free days.

RELEVANCE TO CLINICAL PRACTICE

This study provides evidence-based practice for clinical healthcare providers to adopt the sensory stimulation protocol to prevent delirium, significantly reducing delirium duration and severity.

Delirium in a surgical context from a nursing perspective: A hybrid concept analysis

Background

The term delirium has been defined in medical diagnosis criteria as a multidimensional disorder, and the term acute confusion is included in nursing classifications. Delirium can be a serious complication assessed in a patient after a surgical procedure. Still, the patient's delirium frequently remains unrecognised. Care of patients with delirium after surgical procedure is complex, and it challenges nursing expertise. From the nurses' viewpoint, delirium is associated with ambiguity of concepts and lack of knowledge. Therefore, reseach on how nurses perceive patients with delirium in a surgical context is needed.

Objective

The aim of this study was to describe the concepts of delirium and acute confusion, as well as the associated dimensions, in adult patients in a surgical context from the nursing perspective.

Design

The study used Schwartz and Barcott's hybrid concept analysis with theoretical, fieldwork, and final analytical phases.

Settings

Surgical wards, surgical intensive care units, and post-anaesthesia care units.

Data sources

A systematic literature search was performed through Pubmed (Medline), Cinahl, PsycInfo, and Embase.

Participants

Registered nurses and licensed practical nurses (n = 105) participated in the fieldwork phase.

Methods

In the theoretical phase, the concepts' working definitions were formulated based on a systematic literature search with the year limitations from 2000 until February 2021. At the fieldwork phase, the nurses' descriptions of patients with delirium were analysed using the deductive content analysis method. At the final analytical phase, findings were combined and reported.

Results

The concepts of delirium, subsyndromal delirium, and acute confusion are well defined in the literature. From the perspective of the nurses in the study, concepts were seen as a continuum not as individual diagnoses. Nurses described the continuum of delirium as a process with acute onset, duration, and recovery with the associated dimensions of symptoms, symptom severity, risk factors, and early signs. The acute phase of delirium was emphasised, and preoperative or prolonged disturbance did not seem to be relevant in the surgical care context. Patients' compliance with care may be decreased with the continuum of delirium, which might challenge both patients' recovery from surgery and the quality of nursing care.

Conclusions

In clinical practice the nurses used term confusion inaccurately. The term acute confusion might be used when illustrating an early stage of delirium. Nurses could benefit from further education where the theoretical knowledge is combined with the clinical practice. The discussion about the delirium, which covers the time both before surgery and after the acute phase should be increased.

Prevention and treatment of delirium in intensive care: Hermeneutics of experiences of the nursing team

OBJECTIVE

To understand the experiences in nursing care in the prevention and treatment of delirium in people hospitalized in intensive care units.

METHODOLOGY

Hermeneutic phenomenological qualitative study. The selection of participants was by intentional sampling: seven nursing assistants and eight nurses. Theoretical saturation was achieved. The phenomenological interview was applied to collect data from a central question and the analysis was carried out following the approaches of Heidegger's hermeneutical circle.

RESULTS

Four significant themes emerged from the analysis: (1) delirium prevention, (2) pharmacological treatment, (3) non-pharmacological treatment, and (4) barriers to non-pharmacological treatment. These themes were accompanied by 35 interrelated units of meaning: in the first theme, the most repetitive units were communication, orientation, and family bonding; in the second was the use of pharmacological treatment only in the acute phase; in the third was the modification of the environment according to the patient's preference (where the family is a priority and strategies that provide cognitive and social stimulation can be reinforced), and in the fourth was the work overload for the nursing team.

CONCLUSIONS

The experiences of the nursing team in the prevention and treatment of delirium in critically ill patients highlight that communication allows an approach to the patient as a human being immersed in a reality, with a personal history, needs and preferences. Therefore, family members must be involved in these scenarios, as they can complement and support nursing care.

Development of a non-pharmacologic delirium management bundle in paediatric intensive care units

BACKGROUND

Non-pharmacologic interventions might be effective to reduce the incidence of delirium in pediatric intensive care units (PICU).

AIM

To explore expert opinions and generate informed consensus decisions regarding the content of a non-pharmacologic delirium bundle to manage delirium in PICU patients.

STUDY DESIGN

A two-round online Delphi study was conducted from February to April 2021. PICU experts (nurses, physicians, researchers, physical therapists, play specialists, and occupational therapists) located in Europe, North America, South America, Asia, and Australia participated.

RESULTS

We developed a questionnaire based on the outcomes of a comprehensive literature search in the domains: 1) cognition support; 2) sleep support; and 3) physical activity support. Under these domains, we listed 11 strategies to promote support with 61 interventions. Participants rated the feasibility of each intervention on a 9-point Likert scale (ranging from 1 strongly disagree to 9 strongly agree). A disagreement index and panel median were calculated to determine the level of agreement among experts. In the second round, participants reassessed the revised statements and ranked the interventions in each domain in order of importance for age groups: 0-2, 3-5, and 6-18 years of age. During the first Delphi round, 53 of 74 (72%) questionnaires were completed, and in the second round 45 of 74 (61%) were completed. Five of the highest ranked interventions across the age groups were: 1) developing a daily routine, 2) adjusting light exposure according to the time of day, 3) scheduling time for sleep, 4) providing eyeglasses and hearing aids if appropriate, 5) encouraging parental presence.

CONCLUSIONS

Based on expert consensus, we developed an age-specific non-pharmacologic delirium bundle of interventions to manage delirium in PICU patients.

RELEVANCE TO CLINICAL PRACTICE

An age-specific Non-Pharmacological Delirium bundle is now ready to be tested in the PICU and will hopefully reduce pediatric delirium.

[The nurse's role in preventing delirium in critically ill adult/elderly patientsEl papel de la enfermera en la prevención del delirio en el paciente adulto/anciano críticamente enfermo]

Introduction

Delirium is an acute brain dysfunction, associated with increased mortality and morbidity, which often affects critically ill adult/elderly patients. Nurses have a crucial role in the prevention/control of delirium, through the implementation of non-pharmacological interventions.

Objective

To know the nursing interventions in the identification, prevention and control of delirium in adult/critical elderly patients.

Materials and Methods

An Integrative Literature Review of articles published between 2014 and 2018 was carried out, which identified nursing interventions aimed at the prevention and control of delirium in adult/ critical elderly patients. Four searches were carried out, in the electronic databases of EBSCOhost and B-on.

Results

13 studies were identified, which present nursing interventions, mostly non-pharmacological, for the prevention and control of delirium in adult/critical elderly patients. Of these, interventions related to the environment, sleep promotion, early therapeutic intervention, cognitive assessment and patient orientation, interventions systematized in protocols, as well as interventions aimed at the participation of family members, the training of nurses and the teaching of patients are evident. Risk factors for the development of delirium and assessment tools were also identified.

Discussion

The prevention of delirium is important and imperative, since its occurrence in critically ill patients is associated with increased mortality, morbidity, length of stay and a high hospital cost. The identification of risk factors for the occurrence of delirium should be included in delirium management protocols.

Conclusions

Evidence has shown that nurses are essential in the early identification, prevention and control of delirium, preventing the progression of the disease, contributing to the reduction of morbidity and mortality. The nursing intervention must include the identification of predisposing and/or precipitating factors to contribute to the reduction of the occurrence and/or resolution of delirium.

Effect on Quality of Care of a Delirium Prevention Campaign for Surgical Intensive Care Nurses

BACKGROUND

Delirium is an important issue related to mortality in patients treated in intensive care units.

LOCAL PROBLEM

Although there are guidelines for preventing delirium, its importance may be overlooked compared with the treatment of physical illness.

METHODS

A 2-step delirium prevention campaign (DPC) was implemented and its effects compared (before and after the DPC).

INTERVENTIONS

The DPC comprised the Confusion Assessment Method for the Intensive Care Unit and a checklist for delirium prevention.

RESULTS

Hospital mortality declined after the DPC, but there were no significant changes in the incidence and duration of delirium.

CONCLUSIONS

Nurses led the delirium preventive care intervention. Delirium prevention care may be more effective with policy approaches to progress the DPC.

Effects of nonpharmacological delirium-prevention interventions on critically ill patients' clinical, psychological, and family outcomes: A systematic review and meta-analysis

BACKGROUND

Delirium is common in critically ill patients and may lead to severe complications, such as falls and injuries. Nonpharmacological interventions have been widely suggested to prevent delirium, yet the effects remain uncertain.

OBJECTIVES

The aim of the study was to determine the effects of nonpharmacological interventions on preventing delirium and improving critically ill patients' clinical, psychological, and family outcomes.

METHODS

Ten databases were searched from their inception to September 2020. Two reviewers assessed the methodological quality and extracted details of the included studies. The data were narratively or statistically pooled where appropriate. Dichotomous variables are presented as odds ratio (OR), and continuous variables are presented as mean difference (MD). The Grading of Recommendations Assessment, Development, and Evaluation criteria were used to assess the quality of evidence for each review outcome.

RESULTS

Thirty-four studies (10 randomised controlled trials, eight controlled clinical trials, and 16 before-and-after studies) were included in the analysis. Low-certainty evidence indicated that nonpharmacological interventions reduced delirium incidence (OR = 0.43, 95% confidence interval [CI] [0.33, 0.55]), delirium duration (MD = -1.43 days, 95% CI [-1.94, 0.92]), and length of stay in the intensive care unit (MD = -1.24 days, 95% CI [-2.05, -0.43]). Moderate-certainty evidence demonstrated no effect on mortality. Narrative synthesis further implied improvements in patients' psychological recovery (two studies, very low-certainty evidence) and families' satisfaction with care (two studies, very low-certainty evidence) through nonpharmacological interventions. As for effective intervention types, moderate-certainty evidence demonstrates that early mobilisation (OR = 0.33, 95% CI [0.24, 0.46], five studies, 859 participants, I2 = 24%), family participation (OR = 0.25, 95% CI [0.18, 0.34], four studies, 997 participants, I2 = 21%), and use of multicomponent interventions (OR = 0.48, 95% CI [0.34, 0.69], 13 studies, 3172 participants, I2 = 77%) are associated with reduced incidence of delirium.

CONCLUSIONS

Healthcare professionals are recommended to apply early mobilisation, family participation, or multicomponent interventions in clinical practice to prevent delirium. Further studies investigating the effects of nonpharmacological interventions on patients' psychological and family outcomes are warranted.

The Impact of Nursing Delirium Preventive Interventions in the Intensive Care Unit: A Multicenter Cluster Randomized Controlled Trial

Rationale Delirium is common in critically ill patients and associated with deleterious outcomes. Non-pharmacologic interventions are recommended in current delirium guidelines, but their effects have not been unequivocally established. Objective To determine the effects of a multicomponent nursing intervention program on delirium in the Intensive Care Unit. Methods Stepped wedge cluster randomized controlled trial, conducted in Intensive care units of 10 centers. Adult critically ill surgical, medical or trauma patients at high risk to develop delirium were included. A multicomponent nursing intervention program focusing on modifiable risk factors was implemented as standard of care. Primary outcome was the number of delirium-free and coma-free days alive in 28 days after Intensive Care Unit admission. Measurements and main results A total of 1749 patients were included. Time spent per 8 hours shift on interventions was median [IQR] 38 [14-116] in the intervention period and median 32 [13-73] minutes in the control period (p=0.44). Patients in the intervention period had median 23 [4-27] delirium-free and coma-free days alive, compared to median 23 [5-27] days for patients in the control group (mean difference -1.21 days, 95%CI -2.84 to 0.42 days; p=0.15). Also, the number of delirium days was similar: median 2 [1-4] days (ratio of medians 0.90, 95%CI 0.75 to 1.09; p=0.27). Conclusion In this large randomized controlled trial in adult ICU patients, a limited increase was achieved of the use of nursing interventions, and no change in the number of delirium-free and coma-free days alive in 28 days could be determined. Clinical trial registration available at www.clinicaltrials.gov, ID: NCT03002701.

Nursing intervention to prevent delirium in critically ill adults

OBJECTIVE

To determine the effectiveness of a nursing intervention for delirium prevention in critically ill patients.

METHOD

A quasi-experimental study was conducted with a non-equivalent control group and with evaluation before and after the intervention. 157 Patients were part of the intervention group and 134 of the control group. Patients were followed-up until they were discharged from the ICU or died. The incidence of delirium in both groups was compared. Additionally, the effect measures were adjusted for the propensity score.

RESULTS

The incidence and incidence rate of delirium in the control group were 20.1% and 33.1 per 1000 person-days (CI 95% 22.7 to 48.3) and in the intervention group was 0.6% and 0.64 per 1000 person-days (CI 95% 0.22 to 11.09), respectively. The crude Hazard Ratio was 0.06 (CI 95% 0,008 to 0,45) and adjusted 0.07 (CI 95% 0,009 to 0,60). The number needed to be treated was six.

CONCLUSION

Low incidence of delirium in critically ill patients intervened demonstrated the effectiveness of interventions. The average intervention time was 4 days with a 15-minutes dedication for each patient.

Effects of Preoperative Anxiety on Postoperative Delirium in Elderly Patients Undergoing Elective Orthopedic Surgery: A Prospective Observational Cohort Study

Background

Postoperative delirium (POD) is common and has negative effects on elderly patients. There is a critical need to identify patients at high risk of POD so that providers can better offer targeted interventions in the preoperative and intraoperative periods. We aimed to characterize the prevalence of preoperative anxiety and investigate whether preoperative anxiety predicted the onset of POD in elderly patients undergoing elective orthopedic surgery.

Methods

We conducted a prospective observational cohort study of elderly patients (aged 65 years or older) undergoing elective orthopedic surgery. Preoperative anxiety was assessed using the Hospital Anxiety and Depression Scale-Anxiety (HADS-A), with clinically significant values defined as HADS-A>7. POD was diagnosed according to the Confusion Assessment Method (CAM) criteria on the 5 postoperative days. To determine the independent risk factors for POD, multivariable logistic regression was conducted, including those variables with a p-value <0.05 at univariate analysis.

Results

There were 263 patients included in the study. Seventy-three (27.8%) patients were diagnosed to be POD. Median duration of delirium was 2 days. Forty (15.2%) patients were assessed to experience preoperative anxiety. The occurrence of preoperative anxiety in total hip arthroplasty (THA), proximal femoral nail antirotation (PFNA), and total knee arthroplasty (TKA) was 12.5%, 16.1%, and 19.5%, respectively. Based on multivariable analysis, only age (odds ratio [OR]= 1.099, 95% Confidence Interval [CI]: 1.013–1.192; P=0.023), Mini Mental State Examination (MMSE) (OR= 0.603, 95% CI: 0.432–0.842; P=0.003) and preoperative anxiety (OR= 3.119, 95% CI: 1.144–8.500; P=0.026) were independently associated with POD.

Conclusion

In conclusion, the current study reveals that preoperative anxiety helps to predict the risk of POD in elderly patients undergoing elective orthopedic surgery. Relieving preoperative anxiety could be a new target for preventive interventions to reduce POD.

Predictors of physical restraint use on critical care units: An observational structural equation modeling approach

BACKGROUND

Modifiable unit characteristics, including nurse work environment, education, certification, and staffing have been shown to impact patient safety. Physical restraints are an important patient safety issue, however the relationships between these modifiable unit characteristics and physical restraint use on critical care units has not been explored.

OBJECTIVES

Our objective was to determine the role of nursing work environment, nurse education and certification, and nurse staffing on physical restraint use.

DESIGN

The study was a secondary analysis of 2017-2018 unit-level restraint rates from the National Database of Nursing Quality Indicators linked to Registered Nurse survey and hospital characteristics data.

METHODS

Work environment was examined at the unit-level using total Practice Environment Scale of the Nursing Work Index and subscale scores. Unit-level nurse expertise included the percent of nurses with at least a Bachelor of Science in Nursing degree and percent with certification. Nurse staffing was the unit-level Registered Nurse hours per patient day and skill mix. Analyses included descriptive statistics, bivariate correlations, and Structural Equation Modeling. We used a first order model to estimate predicted restraint use from the five subscales of the Practice Environment Scale of the Nursing Work Index. A higher order model predicted restraint use from a total work environment factor score.

RESULTS

The sample included 408 critical care units from 226 hospitals. Mean restraint rate was 15% (SD 12, range 0-53%). In the first-order model, the Collegial Nurse-Physician Relations subscale had a positive relationship with restraint use (β = 0.167, 95% confidence interval 0.010-0.333). In the higher order model, the total work environment score had a negative relationship with restraint use (β = -0.088, 95% confidence -0.178- -0.014). Registered Nurse hours per patient day had a negative relationship to restraint use in both the first order (β = -0.114, 95% confidence interval -0.222--0.025) and higher order models (β = -0.117, 95% confidence interval -0.223- -0.012).

CONCLUSION

We found that better nurse-physician relationships were associated with higher restraint use. This finding is supported by previous literature and may reflect physician trust in nursing judgement when using restraints. However, a better work environment overall was associated with lower restraint rates. Further, Registered Nurse hours per patient day, but not skill mix, was associated with lower restraint rates. We conclude that improving the overall nurse work environment and nurse staffing, as well as using interprofessional interventions, may be successful in decreasing restraint use on critical care units.

Enfermería en la monitorización del delirium en cuidado intensivo adulto: una revisión de alcance

Introducción. El delirium es una alteración cognitiva secundaria a una situación clínica aguda que puede estar presente en el paciente crítico, y la enfermería juega un rol protagónico en la prevención, monitoreo y tratamiento no farmacológico del delirium en el paciente en unidad de cuidado intensivo. Objetivo. Identificar las investigaciones actuales que describen las estrategias que utilizan las enfermeras para la monitorización del delirium en la unidad de cuidado intensivo adulto. Método. Revisión de alcance, utilizando la pregunta orientadora ¿qué estrategias utiliza enfermería en la monitorización del delirium en la unidad de cuidado intensivo?, estudios obtenidos en las bases de datos PubMed, Biblioteca Virtual en Salud, Science Direct y Cochrane. Se realizó una revisión crítica con el instrumento CASPe, los datos se extrajeron, y se llevaron a cabo registros en tablas de gráficos elaboradas para condensar la información. Resultados. Trece estudios se consideraron relevantes y fueron analizados. Las estrategias de monitorización del delirium empleadas por enfermería son, principalmente, el juicio clínico, la observación de la agitación y, en menor medida, el empleo de instrumentos validados para la detección. Conclusión. La enfermería requiere comprender mejor el delirium, y para esto la educación es vital para mejorar su conocimiento, y aumentar la autoconfianza y competencia en la evaluación a través del uso correcto de instrumentos.

Non-pharmacologic interventions for the prevention of delirium in the intensive care unit: An integrative review

BACKGROUND

Delirium in the intensive care unit (ICU) is associated with increased mortality, longer hospital stays, and increased odds of institutionalization after discharge. Delirium is a significant complication that occurs frequently in ICU yet lacks a standardized treatment protocol. Because of the limited effective pharmacologic treatments available for the management of delirium, non-pharmacologic interventions such as early mobilization, earplugs and blinds at night, music and natural sunlight during the day, continuous reorientation, and increased visitation and family participation are essential to integrate into the treatment plan for the management of delirium in the ICU.

AIM

To summarize evidence on the use of non-pharmacologic interventions for the reduction in incidence and duration of delirium in ICU patients and to integrate qualitative studies that explore the perception of delirium in the ICU from staff and patients' families to support the use of non-pharmacologic interventions.

METHODS

For this integrative review, electronic databases PubMed, EMBASE, and Google Scholar were searched using the guidance of a librarian and second reviewer to find qualitative and quantitative studies that were published after 2005 and involved adult patients in the ICU.

CONCLUSION

Eight quantitative articles and four qualitative articles were chosen to be included in this review. All eight quantitative studies provide significant evidence (P < .05) for the efficacy of their interventions to provide benefit to at least one delirium-related outcome. The four qualitative research studies reviewed provide insight on delirium in the ICU from staff and patients' families who share a desire for the use of effective non-pharmacologic interventions.

RELEVANCE TO CLINICAL PRACTICE

Non-pharmacologic interventions used for patients in the ICU may be efficacious in reducing the incidence and duration of delirium in adults. Non-pharmacologic interventions are feasible and supported by ICU staff and patients' families and should be considered in the care of the critically ill patient.

Early Identification of Delirium in Intensive Care Unit Patients: Improving the Quality of Care

BACKGROUND

Delirium has long-term consequences for intensive care unit patients. The project site, an urban academic hospital, did not previously use a validated delirium screening tool, and patients commonly received sedative medications to treat agitation.

OBJECTIVE

To minimize the risk of delirium by implementing the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) as the standard-of-care delirium assessment tool in the intensive care unit and by decreasing use of high-risk medications (ie, opioids and benzodiazepines).

METHODS

An observational pretest-posttest design was used to analyze deidentified patient data from electronic health records. The evidence-based practice intervention focused on educating nurses on high-risk medications and CAM-ICU implementation. Control charts, χ2 tests, and mixed regression models were used to evaluate the effectiveness of the intervention in reducing delirium risk by decreasing use of high-risk medications.

RESULTS

High-risk medication use significantly decreased after intervention among patients at low risk for delirium (before intervention, 7.37%; after intervention, 3.92%; P < .001) and at high risk for delirium (before intervention, 4.73%; after intervention, 2.99%; P < .001). Hospital stays were significantly shorter in patients at low risk than at high risk for delirium (P < .001) but increased by a mean of 0.13 days with each additional high-risk medication used (P < .001).

CONCLUSIONS

The variation of high-risk medication use was significantly controlled with the implementation of CAM-ICU and education. Nurses felt that hands-on training with the CAM-ICU increased their comfort in identifying patients at risk for delirium. Future work will focus on assessment accuracy.

Protecting Patient Safety and Preventing Modifiable Complications After Acute Ischemic Stroke

TOPIC

Protecting patient safety and preventing modifiable complications after acute ischemic stroke.

CLINICAL RELEVANCE

Stroke is a leading cause of death and disability in adults. Stroke survivors often experience a variety of deficits related to mobility, nutrition, immunity, mood, and cognition. These post-stroke complications and residual effects can adversely affect safety, placing the patient at risk for further injury. In order to develop a plan of care that protects patient safety, critical care and progressive care nurses must understand the unique needs of this patient population.

PURPOSE

To describe selected ischemic stroke-related physiological changes, how these changes contribute to safety risks, and methods of enhancing patient safety.

CONTENT COVERED

Stroke physiology and stroke-specific interventions that can enable nurses to reduce the risk of falls, dysphagia, malnutrition, dehydration, altered glucose metabolism, device-related infections, aspiration pneumonia, delirium, and depression.

Non-pharmacological interventions to reduce the incidence and duration of delirium in critically ill patients: A systematic review and network meta-analysis

OBJECTIVE

To compare non-pharmacological interventions in their ability to prevent delirium in critically ill patients, and find the optimal regimen for treatment.

METHODS

Literature searches were conducted using PubMed, Embase, CINAHL, and Cochrane Library databases until the end of June 2019. We estimated the risk ratios (RRs) for the incidence of delirium and in-hospital mortality and found the mean difference (MD) for delirium duration and the length of ICU stay. The probabilities of interventions were ranked based on clinical outcomes. The study was registered on PROSPERO (CRD42020160757).

RESULTS

Twenty-six eligible studies were included in the network meta-analysis. Studies were grouped into seven intervention types: physical environment intervention (PEI), sedation reducing (SR), family participation (FP), exercise program (EP), cerebral hemodynamics improving (CHI), multi-component studies (MLT) and usual care (UC). In term of reducing the incidence of delirium, the two most effective interventions were FP (risk ratio (RR) 0.19, 95% confidence interval (CI) 0.08 to 0.44; surface under the cumulative ranking curve (SUCRA) = 94%) and MLT (RR 0.43, 95% CI 0.30 to 0.57; SUCRA = 68%) compared with observation. Although all interventions demonstrated nonsignificant efficacy in regards to delirium duration and the length of the patient's stay in the ICU, MLT (SUCRA = 78.6% and 71.2%, respectively) was found to be the most effective intervention strategy. In addition, EP (SUCRA = 97.2%) facilitated a significant reduction in hospital mortality, followed in efficacy by MLT (SUCRA = 73.2%), CHI (SUCRA = 35.8%), PEI (SUCRA = 34.8%), and SR (SUCRA = 31.8%).

CONCLUSIONS

Multi-component strategies are overall the optimal intervention techniques for preventing delirium and reducing ICU length of stay in critically ill patients by way of utilizing several interventions simultaneously. Additionally, family participation as a method of patient-centered care resulted in better outcomes for reducing the incidence of delirium.

What nursing sensitive outcomes have been studied to-date among patients cared for in intensive care units? Findings from a scoping review

BACKGROUND

Although many studies have considered mortality and adverse effects as outcomes sensitive to nursing practice, it seems that other outcomes of nursing care in intensive care units have been explored less commonly.

OBJECTIVES

To describe the state-of-science in research in the field of nursing sensitive outcomes in intensive care units and to synthesize outcomes that have been documented to date as being influenced by nursing care.

DESIGN

A scoping review study based on the framework proposed by Arksey and O'Malley, further refined by the Levac and Joanna Briggs Institute was performed in 2019.

DATA SOURCES

The Medline, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Scopus, and Google Scholar electronic databases were searched. In addition, the reference list of included articles was screened.

REVIEW METHODS

Two researchers independently identified publications on the basis of the following criteria: (a) articles that reported nursing sensitive outcomes on critically-ill adult patients admitted to the intensive care unit, (b) as primary and secondary studies, (c) written in English, and (d) without any time frame limitation.

RESULTS

Of the 4,231 records, 112 fully met the inclusion criteria and were included. Publications were mainly authored in the US and Canada (n = 44, 39.2%), and the majority (n = 62, 55.3%) had an observational design. A total of 233 nursing sensitive outcomes emerged, categorized in 35 outcomes, with, on average, two per study included. The most often measured outcomes were pressure ulcers (20 studies) and ventilator-associated pneumonias (19 studies); the less studied outcomes were quality of life, secretion clearance, patient-ventilator dysynchrony, and post-extubation dysphagia. When categorizing outcomes, the ones concerning safety (n = 77, 33.1%) were represented the most, followed by those concerning the clinical (n = 72, 30.9%), functional (n = 70, 30.0%), and perceptual (n = 14, 6.0%) domains. The interdependent outcomes linked to multi-professional interventions (e.g., ventilator-associated pneumonias) were the most frequently studied nursing sensitive outcomes (n = 20, 57.1%), while independent outcomes resulting from autonomous interventions performed by nurses were less often studied (n = 8, 22.9%).

CONCLUSIONS

From a clinical point of view, a large heterogeneity of outcomes influenced by nursing care emerged. However, identified outcomes have been studied with different approaches and metrics, so that future efforts will need to establish homogeneous conceptual and operative definitions. Moreover, increasing efforts in establishing perceptual outcomes, or those close to the fundamentals of nursing care, are suggested in order to better depict the contribution of critical care nurses in the field.
