Implementation of ABCDEF care bundle in intensive care units: A cross-sectional survey

Effectiveness of a virtual reality-based sensory stimulation intervention in preventing delirium in intensive care units: a randomised-controlled trial protocol

INTRODUCTION

Delirium is a common acute cognitive impairment characterised by confusion, disorientation and attention deficits, particularly prevalent in intensive care unit (ICU) settings. Given its significant impact on patients, caregivers and healthcare resources, preventing delirium in patients in the ICU is of paramount importance. This is the first randomised-controlled trial designed to evaluate the effects of a virtual reality-based sensory stimulation intervention on preventing delirium in ICU patients.

METHODS AND ANALYSIS

We employed a paired randomisation method to match eligible participants based on a validated delirium risk scoring model for patients in the ICU. The study will commence in September 2024 and conclude in June 2026. A consecutive sample of 324 patients in the ICU admitted to the study setting will be recruited. Eligible participants will be randomly allocated to receive either virtual reality-based sensory stimulation in addition to usual care or usual care alone. The virtual reality-based sensory stimulation intervention will last for up to 14 days, with all interventions administered by a research team. We define delirium-free days over a 14-day period as the primary outcome. The secondary outcomes will include delirium incidence, duration and severity; patients' psychological well-being (post-traumatic stress disorder, sleep quality and ICU memory); patients' clinical outcomes and other outcomes (quality of life, independence and cognitive function). Data will be collected at baseline, post-intervention and 6 months post-intervention. Two independent t-tests or Wilcoxon-Mann-Whitney tests will be used for continuous variables, while χ2 or Fisher's exact tests will be employed for categorical variables. The analysis will adhere to both the intention-to-treat and per-protocol principles. Additionally, mixed-effects models and subgroup analysis will be planned.

ETHICS AND DISSEMINATION

This protocol was approved by the Research Ethics Committee of Shenzhen Hospital of Southern Medical University (NYSZYYEC20230068). All participants or their family caregivers will provide written informed consent. Results will be disseminated through scientific publications, and presentations at local and international conferences.

Practices of the ABCDEF care bundle in intensive care units as reported by nurses: A cross-sectional study from Turkey

BACKGROUND

Recent critical care guidelines recommended the evidence-based ABCDEF care bundle for intensive care unit (ICU) patients. However, limited information is available on the implementation of the bundle in Turkish ICUs.

AIM

To assess the current practices of the ABCDEF care bundle as reported by ICU nurses.

STUDY DESIGN

A cross-sectional study using a web-based survey was conducted. Researchers invited nurses with at least 1 year of ICU experience to participate by sending the link to the research questionnaires they created in Google Forms to the one ICU nurse association and one communication group of which they are members.

RESULTS

A total of 342 ICU nurses completed the survey. Although 92% of the participants performed pain assessments in their ICUs, 52.7% reported not using protocols. Based on the responses of the nurses, spontaneous awakening and breathing trials are performed in 88.8% and 92.4%, respectively, of ICUs. Fewer than half of the participants reported following a sedation protocol in their ICUs. Only 54.7% of ICU nurses surveyed reported routinely monitoring patients for delirium. It was reported that early mobilization was practised in 68.7% of ICUs, but non-ventilated patients were mobilized more frequently (70.2%), and 9.7% of ICUs had mobilization teams. Family members were actively involved in 95% of ICUs; however, 9.7% used dedicated staff to support families and 3.5% reported that their unit was open 24 h/day for visits.

CONCLUSIONS

While the implementation of most pain and sedation evaluations in ICUs were reported by nurses, many of them did not use structured delirium assessments. There is a need to encourage early mobilization programs and family participation.

RELEVANCE TO CLINICAL PRACTICE

Health institutions can improve patient care and outcomes by establishing and standardizing a protocol for each component of the ABCDEF care bundle in ICUs.

The barriers to and facilitators of implementing early mobilisation for patients with delirium on intensive care units: A systematic review

Background

Early mobilisation of critically ill patients remains variable across practice. This study set out to determine barriers to and facilitators of early mobilisation for patients diagnosed with delirium in the intensive care unit (ICU).

Methods

A mixed-methods descriptive systematic review. Electronic databases (AMED, BNI, CINAHL Plus, Cochrane Library, Medline and EMBASE) were searched for publications up to 22nd December 2021. Independent reviewers screened studies and extracted data using Covidence Systematic Review Management software. Data were summarised according to frequency (n/%) of barriers and facilitators. Thematic analysis of qualitative studies was carried out in order to address the secondary aim. Quantitative studies were assessed using the GRADE quality assessment tool. Qualitative studies were analysed according to the GRADE-CERQual quality assessment tool. This study was prospectively registered on PROSPERO (CRD 42021227655).

Results

Ten studies met the inclusion criteria. Quantitative findings demonstrated the presence of delirium was the most common reported barrier to early mobilisation. The most common facilitator was ICU staff experience of positive outcomes as a result of early mobilisation interventions. Thematic analysis identified six main themes that may describe potential meanings behind these findings: (1) knowledge, (2) personal preferences, (3) perceived burden of delirium, (4) perceived complexity, (5) decision-making and (6) culture.

Conclusion

These findings highlight the reported need to further understand the impact and value of early mobilisation as a non-pharmacological intervention for patients diagnosed with delirium in ICU. Evaluation of early mobilisation interventions involving key stakeholders may address these concerns and provide effective implementation strategies.

Improving Outcomes in Mechanically Ventilated Adult ICU Patients Following Implementation of the ICU Liberation (ABCDEF) Bundle Across a Large Healthcare System

OBJECTIVES

To measure how the ICU Liberation Bundle (aka ABCDEF Bundle or the Bundle) affected clinical outcomes in mechanically ventilated (MV) adult ICU patients, as well as bundle sustainability and spread across a healthcare system.

DESIGN

We conducted a multicenter, prospective, cohort observational study to measure bundle performance versus patient outcomes and sustainability in 11 adult ICUs at six community hospitals. We then prospectively measured bundle spread and performance across the other 28 hospitals of the healthcare system.

SETTING

A large community-based healthcare system.

PATIENTS

In 11 study ICUs, we enrolled 1,914 MV patients (baseline n = 925, bundle performance/outcomes n = 989), 3,019 non-MV patients (baseline n = 1,323, bundle performance/outcomes n = 1,696), and 2,332 MV patients (bundle sustainability). We enrolled 9,717 MV ICU patients in the other 28 hospitals to assess bundle spread.

INTERVENTIONS

We used evidence-based strategies to implement the bundle in all 34 hospitals.

MEASUREMENTS AND MAIN RESULTS

We compared outcomes for the 12-month baseline and bundle performance periods. Bundle implementation reduced ICU length of stay (LOS) by 0.5 days (p = 0.02), MV duration by 0.6 days (p = 0.01), and ICU LOS greater than or equal to 7 days by 18.1% (p < 0.01). Performance period bundle compliance was compared with the preceding 3-month baseline compliance period. Compliance with pain management and spontaneous awakening trial (SAT) and spontaneous breathing trial (SBT) remained high, and reintubation rates remained low. Sedation assessments increased (p < 0.01) and benzodiazepine sedation use decreased (p < 0.01). Delirium assessments increased (p = 0.02) and delirium prevalence decreased (p = 0.02). Patient mobilization and ICU family engagement did not significantly improve. Bundle element sustainability varied. SAT/SBT compliance dropped by nearly half, benzodiazepine use remained low, sedation and delirium monitoring and management remained high, and patient mobility and family engagement remained low. Bundle compliance in ICUs across the healthcare system exceeded that of study ICUs.

CONCLUSIONS

The ICU Liberation Bundle improves outcomes in MV adult ICU patients. Evidence-based implementation strategies improve bundle performance, spread, and sustainability across large healthcare systems.

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.

Early mobilization practice in intensive care units: A large-scale cross-sectional survey in China

BACKGROUND

The field of early rehabilitation has developed slowly in mainland China and there are limited data on the implementation of early mobilization (EM) practice in intensive care unit (ICUs) in China.

AIMS

To investigate the implementation of EM in ICUs in mainland China and to analyse its influencing factors.

DESIGN

A cross-sectional electronic survey was conducted in 444 ICUs across 11 provinces in China. Head nurses provided data on institutional characteristics and EM practice in ICUs. Logistic regression models were used to identify factors associated with the implementation of EM.

RESULTS

In all, 56.98% (253/444) of ICUs implemented EM with comprehensive or complete implementation in 86 ICUs. Of the 191 ICUs that did not use EM, 136 planned to implement EM in the near future. Of the 253 ICUs that used EM, 21.34% of ICUs implemented EM for all eligible patients, while 24.90% would evaluate and carry out EM within 48 h after ICU admission, 39.13% had collaborative EM teams, 34.39% reported the use of EM protocols, 14.63% reported multidisciplinary rounds and 17.39% had medical orders and charging standards for all EM activities. Only 18.18% of ICUs conducted frequent professional training for EM, and abnormal events occurred in 15.41% of ICUs during EM practice. Multivariate logistic regression analysis revealed that an economically strong province, the presence of a dedicated therapist team, more ICU beds and a higher staff-to-bed ratio favoured the implementation of EM. Furthermore, multidisciplinary rounds, well-established medical orders and charging standards, and a high frequency of professional training can lead to the comprehensive promotion and development of EM practice in ICUs.

CONCLUSIONS

Both the implementation rate and quality of EM practice for critically ill patients require improvement. EM practice in Chinese ICUs is still nascent and requires development in a variety of domains.

RELEVANCE FOR CLINICAL PRACTICE

To facilitate the implementation of EM in ICUs, more human resources, especially the involvement of a professional therapist team, should be deployed. In addition, health providers should actively organize multidisciplinary rounds and professional training and formulate appropriate EM medical orders and charging standards.

Non-pharmacological delirium prevention practices among critical care nurses: a qualitative study

Background

Delirium is common among critically ill patients, leading to increased mortality, physical dependence, and cognitive impairment. Evidence suggests non-pharmacological delirium prevention practices are effective in preventing delirium. However, only a few studies explore the actual implementation and its associated challenges among critical care nurses.

Aim

To explore critical care nurses’ perceptions of current non-pharmacological delirium prevention practices in adult intensive care settings, including delirium screening, early mobilisation, sleep promotion, family engagement, and sensory stimulation.

Methods

A qualitative design adopting a thematic analysis approach. Semi-structured interviews with 20 critical care nurses were conducted in ten acute hospitals in mainland China.

Results

Three themes emerged: (a) importance of family engagement; (b) influence of organisational factors, and (c) suggestions on implementation. The implementation of non-pharmacological delirium prevention practices was limited by a strict ICU visitation policy, lack of routine delirium screening and delirium training, light and noise disturbances during nighttime hours, frequent resuscitation and new admissions and strict visitation policy. Case-based training, adopting a sensory stimulation protocol, and family engagement may be enablers.

Conclusion

ICU care routine that lacks delirium assessment and the strict family visitation policy made it challenging to implement the complete bundle of non-pharmacological practices. Resource deficiency (understaffing, lack of training) and ICU environment (frequent resuscitation) also limited the implementation of non-pharmacological practices. Clinicians could implement case-based training and sensory-stimulation programs and improve communication with family caregivers by instructing family caregivers to recognise delirium symptoms and delirium prevention strategies.
