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

Patient as active partner - clue to successful early mobilization in intensive care

BACKGROUND

The evidence for the benefits of early mobilization in intensive care is growing. Early mobilization differs from most other interventions in intensive care since the patient's participation is requested. What kind of challenges this entails for the intensive care clinicians, and what is crucial in successful early mobilization from their perspective, is sparsely explored and was therefore the purpose of this study.

METHODS

Semi-structured interviews were held with 17 intensive care clinicians, seven nurses, five assistant nurses and five physiotherapists. The interviews were analyzed with a phenomenographic methodology.

FINDINGS

Four descriptive categories emerged: 1) Taking responsibility; 2) Taking the patient's perspective; 3) Time or not time to mobilize; and 4) The "know-how" of early mobilization. Early mobilization was perceived as an important and crucial part of intensive care. It includes positioning and sensory stimulation, which could be used to re-orientate the patient and prevent delirium. The patients' experiences were considered individual with a mix of strong emotions. Despite the stated significance of early mobilization, different conceptions were expressed about the right time, some of them based on concerns for the patient, and some due to safety concerns. In the optimal active mobilization to upright positions there was an emphasis on careful preparation and patient involvement, including negotiation and active participation.

CONCLUSIONS

The importance of early mobilization is indisputable. Successful early mobilization is achieved by applying a person-centered approach, involving the patient as an active partner. Early mobilization comprises positioning and sensory stimulation and should be included in the daily planning of patient care.

The effectiveness of nurses' psychosocial interventions for sensory deprivation in intensive care patients: a systematic review and meta-analysis

OBJECTIVE

This systematic review and meta-analysis aimed to assess the effectiveness of nurses' psychosocial interventions for addressing sensory deprivation in intensive care units (ICUs).

MATERIALS AND METHODS

A comprehensive search of PubMed, Web of Science, EBSCOhost, Google Scholar, CİNAHL, Embase, Cochrane Library, and YÖK Thesis Center databases was conducted from August 2023 to May 2024, without any temporal restrictions. In addition, a physical search was made in the university library for grey literature.

RESULTS

The study revealed that nurses' psychosocial interventions significantly improved patients' level of consciousness (SMD = 1.042, %95 CI = 0.716 to 1.369; Z = 6.25; p < .05) and sleep quality in ICUs (SMD=1.21, 95% CI= 0.232 to 1.810; Z = 2.49; p < .05). The effectiveness of psychosocial interventions varied based on the type of intervention, patient age, ICU type, patient group, and intervention duration. Notably, auditory stimuli and aromatherapy demonstrated particularly high effect sizes, significantly enhancing patients' levels of consciousness and sleep quality.

CONCLUSION

In conclusion, psychosocial interventions aimed at reducing sensory deprivation in intensive care units exert beneficial effects on individuals, notably enhancing their level of consciousness and improving sleep quality.

Nurses' Experiences of the Prerequisites for Implementing Family-Centered Care to Prevent Pediatric Delirium

PURPOSE

The aim of this study was to describe nurses' experiences of the prerequisites for implementing family-centered care to prevent pediatric delirium.

DESIGN

The research employed a qualitative, descriptive study design.

METHODS

A total of 10 nurses working in the pediatric intensive care unit at 1 university hospital participated in the study. The quality data were collected using individual semistructured interviews, and the data were then analyzed by inductive content analysis.

RESULTS

The prerequisites for implementing family-centered care to prevent delirium among pediatric patients consisted of 30 subcategories that were grouped into 11 generic categories. The generic categories were further grouped into 5 main categories: (1) an environment that supports family presence, (2) psychosocial support for the family, (3) individual family involvement, (4) family participation in shared decision-making, and (5) nurses' professional competence.

CONCLUSIONS

According to the nurses' experiences, the implementation of a family-centered approach to preventing delirium in pediatric patients requires creating a supportive environment for families, providing psychosocial support, encouraging family involvement in decision-making, and ensuring that all nurses have the necessary skills.

The parent perspective on paediatric delirium and an associated care bundle: A qualitative study

AIMS

To explore how parents experienced their child with delirium and how parents viewed our delirium management bundle.

DESIGN

We conducted a qualitative exploratory descriptive study using semi-structured individual or dyad interviews.

METHODS

Twelve semi-structured interviews with 16 parents of 12 critically ill children diagnosed with delirium in a paediatric intensive care unit were conducted from October 2022 to January 2023 and analysed through a reflexive thematic analysis.

FINDINGS

We generated five themes: (1) knowing that something is very wrong, (2) observing manifest changes in the child, (3) experiencing fear of long-term consequences, (4) adding insight to the bundle, and (5) family engagement.

CONCLUSION

The parents in our study were able to observe subtle and manifest changes in their child with delirium. This caused fear of lasting impact. The parents regarded most of the interventions in the delirium management bundle as relevant but needed individualization in the application. The parents requested more information regarding delirium and a higher level of parent engagement in the care of their child during delirium.

IMPACT

This paper contributes to understanding how parents might experience delirium in their critically ill child, how our delirium management bundle was received by the parents, and their suggestions for improvement. Our study deals with critically ill children with delirium, their parents, and staff working to prevent and manage paediatric delirium (PD) in the paediatric intensive care unit.

REPORTING METHOD

The consolidated criteria for reporting qualitative research guidelines were used to ensure the transparency of our reporting.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution to the research design. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL COMMUNITY?: - It increases awareness of the parent's perspective on PD in critically ill children. - It shows how PD might affect parents, causing negative emotions such as distress, frustration, and fear of permanent damage. - It shows that the parents in our study, in addition to the care bundle, requested more information on delirium and more involvement in the care of their delirious child.

The effect of nonpharmacological interventions applied by nurses to intensive care patients on the duration of delirium: a meta-analysis study

OBJECTIVE

It was aimed to determine the effect level of nonpharmacological methods applied by nurses to patients hospitalized in the intensive care unit on the duration of delirium.

MATERIALS AND METHODS

For this study, relevant studies were accessed by searching in July-October 2022. After the necessary exclusions were made, 14 studies were included in the study. The total sample size of the studies was 1123.

RESULTS

According to the results, nonpharmacological interventions applied by nurses to intensive care patients were found to reduce the duration of delirium (SMD: - 0.625, 95% CI: - 1.1040-0.210; Z =  - 2.950, p = 0.003, I2 = 93.119%). The country of the study (SMD: - 0.047, p = 0.001) and the types of nonpharmacological interventions used (SMD: - 0.062, p = 0.000) influenced the effect size of modulators on the duration of delirium in ICU patients.

CONCLUSION

Nonpharmacological interventions applied by nurses, who have significant responsibilities in the protection and promotion of health, were found to reduce the duration of delirium in intensive care patients. This study shows that nurses, one of the main components of the multidisciplinary team in intensive care, are successful when they apply nonpharmacological interventions well.

Effect of hospital elder life program on the incidence of delirium: A systematic review and meta-analysis of clinical trials

OBJECTIVE

This meta-analysis aims to investigate the effect of the Hospital Elder Life Program (HELP) on the incidence of delirium, delirium scores, length of hospital stay, and incidence of falls.

METHODS

Four databases (PubMed, Embase, Cochrane Library, and Web of Science) were searched from inception until January 18, 2024. The search specifically targeted randomized controlled trials (RCTs). Two independent researchers conducted literature screening, quality assessment, and data extraction. The meta-analysis was performed using Review Manager 5.4.1 and Stata 15.1 software.

RESULTS

The final analysis included a total of 9 RCTs with 2583 patients. The findings from the meta-analysis indicated that HELP was found to considerably reduce the incidence of delirium and the length of hospital stay when compared to the control group. Nevertheless, no statistically significant differences were observed between the two groups in terms of delirium scores and fall rates.

CONCLUSION

In this meta-analysis, HELP can effectively reduce the incidence of delirium and lead to a shorter hospital stay.

Delirium in the NICU

Delirium in the NICU is an underrecognized phenomenon in infants who are often complex and critically ill. The current understanding of NICU delirium is developing and can be informed by adult and pediatric literature. The NICU population faces many potential risk factors for delirium, including young age, developmental delay, mechanical ventilation, severe illness, and surgery. There are no diagnostic tools specific to infants. The mainstay of delirium treatment is to treat the underlying cause, address modifiable risk factors, and supportive care. This review will summarize current knowledge and areas where more research is needed.

Investigating the effect of implementing a sensory stimulation program by family members on delirium status of brain injury patients hospitalized in the intensive care unit: A randomized clinical trial

BACKGROUND

Delirium is the most common psychological disorder in brain injury patients hospitalized in the intensive care unit (ICU), one of the leading causes of which can be sensory deprivation or sensory overload. This study aimed to determine the effect of implementing a sensory stimulation program by family members on the delirium status of ICU-hospitalized brain injury patients.

MATERIALS AND METHODS

In this randomized controlled clinical trial, 66 brain injury patients hospitalized in the ICUs were assigned to intervention and control groups using stratified random sampling. For the intervention group, a sensory stimulation program was implemented by family members for 1 h a day during the ICU stay. The control group received routine care. Patients' delirium status was assessed daily using the confusion assessment method for the intensive care unit (CAM-ICU). Data were analyzed by the SPSS software version 22, using Chi-square, independent t-test, and Binary logistic regression model tests, at a significance level of 0.05.

RESULTS

Odds of delirium Incidence in the intervention group was 94% lower than in the control group (OR = 0.057, 95% CI 0.017, 0.19, P = 0.001). There is a significant difference between the two groups in terms of length of delirium (P = 0.001), stay in ICU (P = 0.001) and mechanical ventilation (P = 0.001). The mean of all three variables in the intervention group was lower than the control group.

CONCLUSIONS

Implementing of sensory stimulation program by the family members, as a non-pharmacological method, can reduce the incidence of delirium in brain injury patients admitted to ICU.

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.

Non-Pharmacological Nursing Interventions to Prevent Delirium in ICU Patients-An Umbrella Review with Implications for Evidence-Based Practice

Delirium in ICU patients is a complication associated with many adverse consequences. Given the high prevalence of this complication in critically ill patients, it is essential to develop and implement an effective management protocol to prevent delirium. Given that the cause of delirium is multifactorial, non-pharmacological multicomponent interventions are promising strategies for delirium prevention. (1) Background: To identify and evaluate published systematic review on non-pharmacological nursing interventions to prevent delirium in intensive care unit patients. (2) Methods: An umbrella review guided by the Joanna Briggs Institute was utilized. Data were obtained from PubMed, Scopus, EBSCO, Web of Science, Cochrane Library, and Google Scholar. The last search was conducted on 1 May 2022. (3) Results: Fourteen reviews met the inclusion criteria. Multicomponent interventions are the most promising methods in the fight against delirium. The patient's family is an important part of the process and should be included in the delirium prevention scheme. Light therapy can improve the patient's circadian rhythm and thus contribute to reducing the incidence of delirium. (4) Conclusions: Non-pharmacological nursing interventions may be effective in preventing and reducing the duration of delirium in ICU patients.

Delirium on stroke units: a prospective, multicentric quality-improvement project

Background

Post-stroke delirium (POD) in patients on stroke units (SU) is associated with an increased risk for complications and poorer clinical outcome. The objective was to reduce the severity of POD by implementing an interprofessional delirium-management.

Methods

Multicentric quality-improvement project on five SU implementing a delirium-management with pre/post-comparison. Primary outcome was severity of POD, assessed with the Nursing Delirium Screening Scale (Nu-DESC). Secondary outcome parameters were POD incidence, duration, modified Rankin Scale (mRS), length of stay in SU and hospital, mortality, and others.

Results

Out of a total of 799 patients, 59.4% (n = 475) could be included with 9.5% (n = 45) being delirious. Implementation of a delirium-management led to reduced POD severity; Nu-DESC median: pre: 3.5 (interquartile range 2.6–4.7) vs. post 3.0 (2.2–4.0), albeit not significant (p = 0.154). Other outcome parameters were not meaningful different. In the post-period, delirium-management could be delivered to 75% (n = 18) of delirious patients, and only 24 (53.3%) of delirious patients required pharmacological treatments. Patients with a more severe stroke and POD remained on their disability levels, compared to similar affected, non-delirious patients who improved.

Conclusions

Implementation of delirium-management on SU is feasible and can be delivered to most patients, but with limited effects. Nursing interventions as first choice could be delivered to the majority of patients, and only the half required pharmacological treatments. Delirium-management may lead to reduced severity of POD but had only partial effects on duration of POD or length of stay. POD hampers rehabilitation, especially in patients with more severe stroke.

Intensive Care-Related Cognitive Impairment: A Biopsychosocial Overview

Advancements in critical care medicine have improved survival rates for patients experiencing critical illness in intensive care units (ICUs). While mortality has declined, more than half of ICU survivors experience functional impairments that persist beyond discharge. Of particular concern is ICU-related cognitive impairment, which can extend across the care continuum, ranging from acute and transient presentations in the ICU (eg, delirium) to long-term impairments years after discharge. ICU-related cognitive impairment has received increased attention in the literature, particularly as it relates to ICU survivors who have received and survived critical care in the context of SARS-CoV-2 pandemic and are now experiencing post-acute sequelae of SARS-CoV-2 infection. The medical complexity and heterogeneity of ICU survivors, coupled with the multifactorial etiology of ICU-related cognitive impairments, lead to challenges in how to optimize care for ICU survivors at various stages of recovery. This review aims to provide an overview of cognitive outcomes associated with critical illness by integrating recent literature focused on etiology, assessment, and interventions in the context of ICU-related cognitive impairments. The narrative review employs a biopsychosocial framework to comprehensively evaluate the multifactorial nature of ICU-related cognitive outcomes. Authors also highlight multidisciplinary teams composed of key rehabilitation providers are likely best suited for optimizing recovery trajectories of ICU survivors.

Non-Pharmacological Nursing Interventions for Prevention and Treatment of Delirium in Hospitalized Adult Patients: Systematic Review of Randomized Controlled Trials

Delirium is a common neurobehavioral complication in hospitalized patients that can occur in the acute phase and lead to poor long-term outcomes. The purpose of this study was to identify non-pharmacological nursing interventions for the prevention and treatment of delirium in hospitalized adult patients. We conducted a systematic review to synthesize the findings of published studies. We searched the PubMed, EMBASE, CINAHL, and Cochrane Library CENTRAL databases for randomized controlled trials in January 2021. We report this systematic review according to the PRISMA 2009 checklist. The study was registered on PROSPERO (CRD42021226538). Nine studies were systematically reviewed for non-pharmacological nursing interventions for the prevention and treatment of delirium. The types of non-pharmacological nursing interventions included multicomponent intervention, multidisciplinary care, multimedia education, music listening, mentoring of family caregivers concerning delirium management, bright light exposure, ear plugs, and interventions for simulated family presence using pre-recorded video messages. These results could help nurses select and utilize non-pharmacological nursing interventions for the prevention and treatment of delirium in clinical nursing practice.

Pain and its management: Dante's Divine Comedy

Dante Alighieri died in 1321; therefore, 2021 is the 700th anniversary of his death. His best known work is the Divine Comedy, which explores Dante's journey through the three realms of the underworld. Each realm is associated with three different sensations: Inferno, bodily (pain); Purgatorio, acoustic (music); and Paradiso, visual (light). The progression of the painful experiences and the resolution through music and light mirror the modern understanding of pain and its management. Music has both direct and indirect benefits and can help with coping. Sunlight promotes well-being and self-awareness.
