Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will receive the protocolised ABCDEF bundle of cares which is outlined below:
A: - Assess, prevent and manage pain: Pain will be assessed every 2 hours and when necessary using the Numeric Rating Scale (NRS) if the patient is conscious or the Critical Care Observation Tool (CCOT) if unconscious. Significant pain will be assumed if the NRS is greater than 4 or the CCOT is greater than 3. Pre-procedural analgesia will be administered as per medical officer's prescription. “Treat pain first, then sedate” will be emphasised.
B: - Both Spontaneous awakening trial (SAT) and spontaneous breathing trial (SBT)
This component relates to mechanically ventilated patients. Sedative medications will be ceased daily, the patient will be orientated to time and day, and an SBT will be conducted to liberate the patient from the ventilator. A safety screen within the CIS will be completed by the RN every morning to determine whether it is safe to interrupt sedation and commence a SAT. The Consultant must agree to both the SAT and SBT before progressing.
C: - Choice of analgesia and sedation. Level of alertness will be monitored every 4 hours with the Richmond Agitation and Sedation Scale (RASS). ICU nursing and medical staff will optimise sedation by keeping the RASS between light sedation (-2) to restless (+1) for mechanically ventilated patients unless it is deemed not appropriate by the treating consultant.
D: - Delirium: assess, prevent and manage. The CAM-ICU will be performed every 12 hours (8am and 8pm) on patients with a RASS score of -2 or higher to determine if the patient is delirious. Reorientation and cognitive stimulation activities will be performed by the occupational therapist and nursing staff. Patients will be provided their glasses and hearing aids throughout the day. Shower and bed bath will be considered once the patient is conscious and haemodynamically stable. The use of physical restraints will be avoided. Patients will be taken outside to the courtyard each day- weather permitting. Patients will receive a sleep hygiene program that will occur from 11 pm to 5 am and will include the use of earplugs, reduction in light and noise, and organisation of care activities to provide maximum uninterrupted sleep.
E: - Early mobility and exercise. The physiotherapist and nursing staff will ensure the early mobility and exercise program is incorporated into patient care. The completion of a screen within the Clinical Information System (CIS) will ensure the patient meets safety criteria. The patient will progress through four levels of progressive activity, receiving the highest level they can manage. Level 1: If the patient does not pass the safety screen, they will receive passive range of motion exercise and sitting position three times a day in bed. Level 2: If the patient can lift their arm on request, they will receive active resistance exercises, will sit in bed at a sitting position three times per day, and will sit on the edge of the bed daily. Level 3: If able to lift their leg on request, the patient will receive level 2 exercises and will also trial a stand once per day. Level 4: If the patient can lift their leg and managed level 3 the previous day, they will receive level 3 exercises and will be encouraged to ambulate- march in place, or take a few steps, or walk with assistance.
F: - Family engagement and empowerment. The F component of the bundle focuses on strategies that are respectful of and responsive to patient and family needs and values, enhance family satisfaction with patient care, enhance decision-making, and acknowledge that delirious patients often feel greater trust toward family members versus staff. Families within the intervention group will be offered the following: face to face meeting with a member of the medical team (Monday - Sunday) or with the social worker (Monday – Friday). At this meeting, the family will be provided an update on the patient's status. The family will be given the opportunity to have questions answered and concerns addressed. Family members will receive an information brochure related to delirium on admission to the ward (Delirium in the Intensive Care Unit - A guide for Families and Patients developed by Critical Illness, Brain Dysfuction, and Survivorship (CIBS) Center, Nashville USA.) Family members will be encouraged to be actively involved in delirium management and exercise components of the protocol under supervision of the treating team. This involvement may include bringing in photos and personal items from home, ensuring hearing aids and glasses are used, re-orientating the patient, reading to and talking to the patient, bringing in favorite music, spreading out visits throughout the day, assisting the patient with Level 1 and 2 exercise as described in component E.
Data related to adherence to each component of the ABCDEF protocol will be collected. The bed-side Registered Nurse will record each component of the ABCDEF bundle as it is delivered within the ICU clinical information system. The Principal Investigator will retrospectively record this data on a case report form. Reasons for not completing components of the ABCDEF bundle will be recorded by the bedside nurse.
The intervention will continue until the patient is considered suitable to transfer to a ward.
Intervention code [1] 317513 0
Prevention
Comparator / control treatment
Participants in the control group will receive standard medical, nursing, and allied health care. Standard care includes decisions made on a daily basis with no use of protocols: spontaneous breathing and awakening trials as determined by the Consultant Intensivist on duty; ad hoc management of pain and delirium; once or twice daily passive and active exercise as determined by the physiotherapist of the day with patients generally remaining in bed if they are ventilated.
Potential contamination of the control group has been considered. The intervention group will receive the protocolised ABCDEF bundle via a prescription within the CIS. The control group will not have access to the ABCDEF protocols as they will not be available in any other format. Variation in the control group will relate to different clinical practice and effort of individuals

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment is guaranteed as a secure web-based randomisation system from Griffith University will be used and will only release a randomisation code once the patient has completed screening procedures and has been formally consented.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised to the intervention group who will receive the protocolised bundle of ABCDEF cares or the control group who will receive standard medical, nursing and physiotherapy care using a secure web-based randomisation system from Griffith University. The allocation sequence will be computer-generated in a ratio of 1:1, using randomly varied block sized of 2 and 4 to avoid predictability of allocation and to ensure even groups.

Statistical methods / analysis
The primary outcome measure is incidence and duration of delirium. It is difficult to predict numbers of delirious patients in the ICU as they have been reported to be as low as 19% or as high as 87%. A pre-post study by Balas and colleagues has been used to guide the primary outcome measure to calculate sample size. In order to have 80% power to identify a change in percentage of patients with delirium at any time from 65% to 42.5% or less (i.e. a change of 22.5%), 75 patients will be required in each of the treatment group and control group (total of 150 patients) .
Patients with at least 48 hours in the ICU will be included in the statistical analysis. Descriptive statistics will be used to determine the frequency and percentage of the intervention and the control group participants’ demographic variables. Values will be compared to ascertain mean outcomes and to test whether statistical assumptions for parametric tests are met. Analyses will be performed on a basis of an intention-to-treat and per protocol method. Continuous variables that are normally distributed will be compared using the independent t-test. Non-parametric analysis will be conducted for continuous variables that are not normally distributed. Categorical variables will be tested with the chi-square statistic. Regression models will be used to explain confounders (receipt of certain medications including benzodiazepines and muscle relaxants). Patients who die during the ICU stay will be assigned a score of 0 for ventilator free days, ICU free days, and hospital free days. A p value of p < 0.05 will be considered statistically significant. Where appropriate, analyses will be reported with mean differences and 95% confidence interval (CI). Protocol violations will be noted. Imputation will be used to correct for missing data where appropriate. Statistical analysis will be performed using IBM Statistical Package for Social Sciences (SPSS) software, version 26.0.

Summary
Brief summary
The purpose of this study is to find out whether ventilated adult patients admitted to the Intensive Care Unit (ICU) who receive the ABCDEF bundle of cares will have reduced prevalence and duration of delirium, improved functional ability, and improved health related quality of life when discharged from the ICU and hospital compared to patients who receive our usual care.
Delirium is an acutely disturbed state of mind characterised by restlessness, illusions, and incoherence. Functional ability relates to the participant’s ability to mobilise and care for themself, while health related quality of life relates to the impact of the participant’s health status on their quality of life.
Mechanical ventilation, bed rest, the use of pain medication and sedatives are usual practices for some patients in Intensive Care Units (ICU). Unfortunately, these practices can be associated with both physical and psychological complications such as muscle weakness and delirium.
The ABCDEF bundle of cares refers to:
• Assess, prevent and manage pain
• Both spontaneous awakening and spontaneous breathing trials
• Choice of sedation and analgesia
• Delirium: assess, prevent and manage
• Early mobility and exercise
• Family engagement and empowerment
This bundle of cares involves using protocols that give the least amount of sedatives and pain relief necessary to keep the participant comfortable and settled, encourages early and safe weaning from the ventilator, mobilises the participant at the earliest and safest time, and aims to enhance family satisfaction with the participant care.
