1. ABCDE Protocol ICU Delirium and Cognitive Impairment Study Group www.icudelirium.org delirium@vanderbilt.edu

2. Why the ABCDE Protocol?

3. Need for Sedation and Analgesia Prevent pain and anxiety Decrease oxygen consumption Decrease the stress response Patient-ventilator synchrony Avoid adverse neurocognitive sequelae - Depression, PTSD Rotondi AJ, et al. Crit Care Med. 2002;30:746-752. Weinert C. Curr Opin in Crit Care. 2005;11:376-380. Kress JP, et al. Am J Respir Crit Care Med. 1996;153:1012-1018.

4. Potential Drawbacks of Sedative and Analgesic Therapy Oversedation: Failure to initiate spontaneous breathing trials (SBT) leads to increased duration of mechanical ventilation (MV) Longer duration of ICU stay Impede assessment of neurologic function Increase risk for delirium Numerous agent-specific adverse events Kollef MH, et al. Chest. 1998;114:541-548. Pandharipande PP, et al. Anesthesiology. 2006;104:21-26.

5. Patient with Sepsis Mechanical Ventilation Sedation Weakness Delirium Cognitive and Functional Impairment, Institutionalization, Mortality Vasilevskis et al Chest 2010; 138;1224-1233

6. We Need Coordinated Care Many tasks and demands on critical care staff Great need to align and supporting the people, processes, and technology already existing in ICUs ABCDE protocol is multiple components, interdependent, and designed to: Improve collaboration among clinical team members Standardize care processes Break the cycle of oversedation and prolonged ventilation Vasilevskis et al Chest 2010; 138;1224-1233

7. What is the MIND-USA ABCDE Protocol? Awakening and Breathing Coordination Delirium Identification and Management ABC D Early Exercise and Mobility E

8. ABC Awakening and Breathing Coordination

9. ICU Sedation: Its a Balancing Act

10. Consequences of Suboptimal Sedation Inadequate sedation/analgesia Anxiety Pain Patient-ventilator dyssynchrony Agitation Self-removal of tubes/catheters Care provider assault Myocardial ischemia Family dissatisfaction Excessive sedation Prolonged mechanical ventilation, ICU LOS Tracheostomy DVT, VAP Additional testing Added cost Inability to communicate Cannot evaluate for delirium

11. Structured Approaches to Sedation & Analgesia in the ICU 1. Multidisciplinary development, implementation 2. Establish goals/targets, frequently re-evaluate 3. Measure key components using validated scales 4. Select medications based on characteristics, evidence 5. Incorporate key patient considerations 6. Prevent oversedation, yet control pain and agitation 7. Promote multidisciplinary acceptance and integration into routine care Sessler & Pedram. Crit Care Clinics 2009; 25:489-513

12. Validated ICU Sedation Scales Richmond agitation-sedation scale (RASS) Sedation agitation scale (SAS) Ramsay sedation scale Motor activity assessment scale (MAAS) Vancouver interactive and calmness scale (VICS) Adaptation to intensive care environment (ATICE) Minnesota sedation assessment tool (MSAT)

13. Setting Targets Provide for agitation/anxiety free, amnesia, comfort Trying to achieve a balance TIGHT TITRATION Adjust target depending on current need Per patient Different over the course of Illness/Treatment

14. Use Protocols to Achieve Goals, Minimize Drug Accumulation, Maximize Alertness Patient-focused drug selection Preference for analgesia > sedation Intermittent therapy via boluses Frequent evaluation of sedation, pain, ICU therapy tolerance Titrate therapy for lowest effective dose Daily interruption of sedation

15. RCT: 2x2 factorial design Midazolam vs propofol Daily interruption of sedation vs routine Discontinue all sedative and analgesic medications Monitor patient closely until awake or agitated, i.e., can perform at least 3 of 4 on command: Open eyes Squeeze hand Lift head Stick out tongue Restart medications at half dosage (if necessary) Kress et al. N Engl J Med 2000; 342:1471-7

16. Daily Awakening Trial Results Shorter duration of mechanical ventilation Shorter ICU LOS Fewer tests for altered mental status Kress et al. N Engl J Med 2000; 342:1471-7

17. Why Is Interruption of Sedation Effective? Less accumulation of sedative drug and metabolites Significantly less midazolam and morphine with DIS in midazolam subgroup But no difference in amount of propofol and morphine with DIS in propofol subgroup Opportunity for more effective weaning from mechanical ventilation? Wake Up and Breathe Sessler CN. Crit Care Med 2004 Kress et al. NEJM. 2000

18. Multicenter RCT: 168 patients with spontaneous awakening trial (SAT) i.e., daily interruption of sedation (SAT) + spontaneous breathing trial (SBT) 168 patients with standard sedation + SBT

20. SAT + SBT Was Superior to Conventional Sedation + SBT Intervention (SAT) group = Less benzodiazepine Extubated faster Discharged from ICU sooner P = 0.01 P = 0.02 Girard et al. Lancet 2008; 371:126-34

21. SAT + SBT Was Superior to Conventional Sedation + SBT Discharged from hospital sooner Better survival at 1 yr P = 0.04 P = 0.01 Alive P = 0.01 P = 0.02 Intervention (SAT) group = More unplanned extubation, but not more reintubation Girard et al. Lancet 2008; 371:126-34

22. Awakening & Breathing Coordination Synergy of daily awakening via interruption of sedation plus spontaneous breathing trial Less medication accumulation, less excessive sedation Opportunity for more effective independent breathing (SBT) Perform safety screens for SAT and for SBT

23. ABC Safety Screens Wake Up Safety Screen No active seizures No active alcohol withdrawal No active agitation No active paralytic use No myocardial ischemia (24h) Normal intracranial pressure Breathe Safety Screen No active agitation Oxygen saturation >88% FiO2 < 50% PEEP < 7.5 cm H2O No active myocardial ischemia (24h) No significant vasopressor use Girard et al. Lancet 2008; 371:126-34. Kress et al. Crit Care Med 2004; 32(6):1272-6 Ely et al. NEJM 1996; 335:184-9

24. ABC Awakening & Breathing Coordination Eligibility = On the ventilator 1. SAT Safety Screen - pass/fail 2. If pass safety screen, perform SAT If fail; restart sedatives if necessary (1/2 dose) If pass; continue to SBT safety screen 3. SBT Safety Screen - pass/fail 4. If pass safety screen, perform SBT If fail; return to previous ventilatory support If pass; consider extubation

25. D Delirium Monitoring and Management

26. Delirium: Key Features 1. Disturbance of consciousness with reduced ability to focus, sustain or shift attention 2. A change in cognition or the development of a perceptual disturbance that is not better accounted for by pre-existing, established or evolving dementia 3. Develops over a short period of time and tends to fluctuate over the course of the day 4. There is evidence from the H&P and/or labs that the disturbance is caused by a medical condition, substance intoxication or medication side effect

27. Delirium Subtypes Hyperactive Delirium Combative Agitated Restless Mixed Delirium Alert & Calm Lethargic Sedated Stupor Hypoactive Delirium

28. ICU Delirium Increased ICU length of stay (8 vs 5 days) Increased hospital length of stay (21 vs 11 days) Increased time on ventilator (9 vs 4 days) Higher ICU costs ($22,000 vs $13,000) Higher ICU mortality (19.7% vs 10.3%) Higher hospital mortality (26.7% vs 21.4%) 3-fold increased risk of death at 6 months Ely, et al. ICM2001; 27, 1892-1900 Ely, et al, JAMA 2004; 291: 1753-1762 Lin, SM CCM 2004; 32: 2254-2259 Milbrandt E, et al, Crit Care Med 2004; 32:955-962. Ouimet, et al, ICM 2007: 33: 66-73.

29. Confusion Assessment Method for the ICU (CAM-ICU) Feature 1: Acute change or fluctuating course of mental status And Feature 2: Inattention And Feature 3: Altered level of consciousness Feature 4: Disorganized thinking Or Inouye, et. al. Ann Intern Med 1990; 113:941-948.1 Ely, et. al. CCM 2001; 29:1370-1379.4 Ely, et. al. JAMA 2001; 286:2703-2710.5

30. Delirium Management 1. Identify etiology 2. Identify risk factors 3. Consider pharmacologic treatment Jacobi J, et al. Crit Care Med 2002;30:119-141

31. Stop and THINK Do any meds need to be stopped or lowered? Toxic Situations CHF, shock, dehydration New organ failure (liver/kidney) Hypoxemia Infection/sepsis (nosocomial), Immobilization Nonpharmacologic interventions Hearing aids, glasses, reorient, sleep protocols, music, noise control, ambulation K+ or electrolyte problems Especially consider sedatives Is patient on minimal amount necessary? Daily sedation cessation Targeted sedation plan Assess target daily Do sedatives need to be changed? Remember to assess for pain! Consider antipsychotics after evaluating etiology & risk factors

32. Delirium Nonpharmacologic Interventions Eligibility = RASS -3 +4 +3 +2 +1 0 -1 COMBATIVE VERY AGITATED AGITATED RESTLESS ALERT & CALM DROWSY Combative, violent, immediate danger to staff Pulls to remove tubes or catheters; aggressive Frequent non-purposeful movement, fights ventilator Anxious, apprehensive, movements not aggressive Spontaneously pays attention to caregiver Not fully alert, but has sustained awakening to voice (eye opening & contact >10 sec) -2 LIGHT SEDATION Briefly awakens to voice (eyes open & contact <10 sec) -3 MODERATE SEDATION Movement or eye opening to voice (no eye contact) -4 DEEP SEDATION No response to voice, but movement or eye opening to physical stimulation -5 UNAROUSEABLE No response to voice or physical stimulation

33. Delirium Nonpharmacologic Interventions Pain: Monitor and manage pain using an objective scale (e.g., FACES, BPS, VAS, CPOT, etc.) Orientation: Convey the day, date, place, and reason for hospitalization Update the whiteboards with caregiver names Request placement of a clock and calendar in room Discuss current events

34. Nonpharmacologic Interventions Sensory: Determine need for hearing aids and/or eye glasses If needed, request surrogate provide these for patient when appropriate Sleep: Noise reduction strategies (e.g. minimize noise outside the room, offer white noise or earplugs) Normal day-night variation in illumination Use time out strategy to minimize interruptions in sleep Maintain ventilator synchrony Promote comfort and relaxation (e.g., back care, oral care, washing face/hands, and daytime bath, massage)

35. E Early Exercise and Mobility

36. Early Exercise in the ICU Early exercise = progressive mobility Study design: paired SAT/SBT protocol with PT/OT from earliest days of mechanical ventilation Wake Up, Breathe, and Move Schweickert WD, et al. Lancet. 2009;373:1874-1882.

37. Early Exercise Study Results Intervention (n=49) Control (n=50) Outcome P Functionally independent at discharge 29 (59%) 19 (35%) 0.02 ICU delirium (days) 2.0 (0.0-6.0) 4.0 (2.0-7.0) 0.03 Time in ICU with delirium (%) 33 (0-58) 57 (33-69) 0.02 Hospital delirium (days) 2.0 (0.0-6.0) 4.0 (2.0-8.0) 0.02 Hospital days with delirium (%) 28 (26) 41 (27) 0.01 Barthel index score at discharge 75 (7.5-95) 55 (0-85) 0.05 ICU-acquired paresis at discharge 15 (31%) 27 (49%) 0.09 Ventilator-free days 23.5 (7.4-25.6) 21.1 (0.0-23.8) 0.05 Length of stay in ICU (days) 5.9 (4.5-13.2) 7.9 (6.1-12.9) 0.08 Length of stay in hospital (days) 13.5 (8.0-23.1) 12.9 (8.9-19.8) 0.93 Hospital mortality 9 (18%) 14 (25%) 0.53 Schweickert WD, et al. Lancet. 2009;373:1874-1882.

38. Early Exercise and Mobility Eligibility = All patients are eligible for Early Exercise and Mobility

39. Perform Safety Screen First Safety Screen Patient responds to verbal stimulation (i.e., RASS > -3) FIO2 <0.6 PEEP <10 cmH2O No dose of any vasopressor infusion for at least 2 hours No evidence of active myocardial ischemia (24 hrs) No arrhythmia requiring the administration of new antiarrhythmic agent (24hrs) If patient passes Exercise/Mobility Safety Screen, move on to Exercise and Mobility Therapy If patient fails, s/he is too critically ill to tolerate exercise/mobility

40. Early Exercise & Mobility Levels of Therapy* 1. Active range of motion in bed and sitting position in bed 2. Dangling 3. Transfer to chair (active), includes standing without marching in place 4. Ambulation (marching in place, walking in room or hall) *All may be done with assistance.

41. Early Exercise and Mobility Protocol Progression RASS -5 / -4 RASS -3 Active ROM (in bed) No Exercises, but Passive Range of Motion allowed Progress as tolerated Exercise screen ICU Discharge Sit/ Dangle Transfer March/ Walk
