Learning Objectives: To be able to: Describe risk factors, outcomes associated with ICU delirium. Diagnose delirium in ICU patients. Know the elements of the ABCDEF Bundle. Implement the ABCDEF Bundle in your ICU.
Acute onset of cerebral dysfunction, characterized by 3 features*: A change or fluctuation in baseline mental status. Inattention. and either disorganized thinking, or an altered level of consciousness. *In: DSM-V, American Psychiatric Association, 2013
Symptoms of ICU Delirium Hallucinations, delusions Sleep disturbances Abnormal psychometric activity (e.g., agitation, lethargy) Emotional disturbances (e.g., fear, anger, depression, apathy)
Subtypes of ICU Delirium Mixed (9%-54%) Hyperactive (1-2%) Hypoactive (44%-90%) (Easy to identify!) (Worse outcomes!) Pandharipande, IntCareMed (2007) 33:1726 1731 Peterson, J Am Geriatr Soc (2006) 54:479 484
Epidemiology of ICU delirium Incidence: Risk factors: 60-80% of Mech. Ventilated ICU patients 20-50% of non-mv ICU patients Baseline: dementia, HTN, ETOH, acuity ICU acquired: deep sedation, coma, benzodiazepines Outcomes: ICU/Hospital: duration of MV, LOS, mortality Post-D/C: PTSD, cognitive dysfunction, physical disability, SNF placement, mortality Costs: 39% ICU costs, 31% hospital costs* $6.5 - $20.4 billion annually** *Milbrandt EB, et al.

ICU Delirium - What ICU Survivors Say I saw outlines of skeletons on the wall, heard strange sounds, etc. I believed I had been moved into various parts of the hospital, including the basement. I misinterpreted environmental cues and attempts to help me were interpreted as meanness. I actually saw body bags with my children's names on them! I tried to help them and I tried to communicate this to others, but with the tracheostomy tube I was unable to do this. After I was extubated and sedation was discontinued, I continued to have paranoid delusions about the nurses wanting to harm me. I repeatedly told my family that when I was dead, the nurses were going to put my body in a large trash can at the foot of my bed.
Causes of ICU Delirium Cholinergic activity Genetic predisposition Dopaminergic activity Primed microglial cells / Serotonergic activity Cavallazzi R, Annals of Intensive Care 2012, 2:49 GABA/NMDA receptor imbalance
Delirium goes undetected in most ICU patients. Validated delirium assessment tools ICU delirium dx. CAM-ICU, ICDSC are the most valid, reliable tools.* Delirium assessments should be performed >Q shift in all pts.* Routine delirium assessments are feasible in clinical practice.** *Barr J, Crit Care Med 2013; 41:263 306 **Vasilevskis EE, J Am Geriatr Soc 2011; 59 (Suppl 2):S249 S255
ICU Delirium Detection Rates Delirium goes undetected in 72% of ICU patients. Hypoactive delirium is harder to diagnose without using a validated assessment tool. Only 25-59% of ICU MDs screen ICU pts. for delirium (2/3 use clinical judgement). Use of a validated ICU delirium assessment tool RN delirium detection rates (27% 92%).* *Mistarz R, Aust Crit Care. 2011 May;24(2):126-32

ICU Delirium Management Strategies Non- Pharmacologic Delirium Rx
What are Non-Pharmacologic ICU Delirium Management Strategies?
Non-Pharmacologic ICU Delirium Management Strategies 1. Optimize pain management 2. Avoid deep sedation 3. Eliminate deliriogenic medications 4. Facilitate ventilator weaning 5. Remove lines and tubes 6. Avoid restraints 7. Reorient patients 8. Promote normal sleep-wake cycles 9. Mobilize patients early 10. Engage ICU patients and families
Optimize ICU Pain Management Assess pain Q2hr, prn: NRS = 0 10 (self-report) CPOT (0 8) or BPS (3 12) (non-self report) Treat significant pain first before sedating pts (analgosedation): NRS 4 CPOT 3, BPS 6 Pain management: Non-neuropathic pain: IV opioids Neuropathic pain: PO gabapentin, carbamazepine Adjunctive: IV acetaminophen, NSAIDs, ketamine Thoracic epidurals: rib fractures, s/p AAA repair Barr J, et al.

Sleep Deprivation and ICU Delirium??
ICU Sleep Hygiene Programs Create a protected nighttime sleeping period (i.e., 2200 hr 0600 hr): Minimize, cluster patient care activities. Decrease light and noise in the patient s room. Have patients wear earplugs, eye masks. Use relaxation techniques (e.g., soothing music, massage, aromatherapy) Avoid sedatives, caffeinated beverages (i.e., nighttime sedation sleep promotion) Increase daytime activity: Increase mobility Open window shades Avoid daytime naps Oral melatonin Qhs?

How to implement the ABCDEF Bundle in Your ICU HELP! VS. Where to begin????
Implementing ABCDEF Bundle Elements Seven Steps to Success! STEP 1: Implement Pain, Sedation, Delirium assessment tools. STEP 2: Incorporate PAD assessments into daily ICU care plan. STEP 3: Create ICU specific PAD management protocols. STEP 4: Integrate PAD protocols w/ SATs, SBTs, EM protocols. STEP 5: Engage ICU patients and families. STEP 6: Measure Bundle Compliance, Performance. STEP 7: Measure Bundle impact on ICU patient outcomes. *Pun BT, et al. Semin Resp Crit Care Med 2013;34:223 235.
Step 1: Implement ICU Pain, Sedation, and Delirium Assessment Tools Pain, coma, & delirium = barriers! You don t know what you don t measure! SAT-SBT, Mobility, Family Engagement HOUSE OF PAD ICU PAD Protocols PAD Assessment Tools Assessments without protocols won t change practice!
Step 2: Incorporate PAD Assessments Into the Daily ICU Care Plan What is the patient s current pain score and their analgesia regimen? What is the patient s current and target sedation scores, and their current sedation regimen? What is the patient s current delirium score and what are their delirium risk factors? How do these PAD assessment influence our ICU care plan for today?
Step 3: Create ICU Specific Pain, Agitation, and Delirium Management Protocols Make protocols specific to your ICU culture, formulary. Use opt out rather than opt in protocol designs. Protocol benefits: Help transfer EBM best practices to the bedside. Limit practice variation. Reduce treatment delays. Improve ICU patient outcomes. Link to quality assurance efforts.
Step 4: Integrate PAD Management Early Mobility Pain Management SATs Sedation/ Agitation Management Delirium Management SBTs
Step 5: Engage ICU Patients and Families
