1 Delirium Prevention: The State-of-the-Art & Implications to Improve Care in our State Jonny Macias, MD & Michael Malone, MD Aurora Health Care/ University of Wisconsin School of Medicine & Public Health May 19, 2014

2 Objectives Describe delirium Describe the Hospital Elder Life Program (HELP) as a model of care to prevent delirium. Explain how the HELP model can be integrated into the electronic medical record. Describe how the two models (Acute Care for Elders and HELP) can be integrated to improve care for vulnerable older patients. Define the HELP- Wisconsin project: a state-wide, collaborative for delirium prevention. 3

4 Delirium: early descriptions Celsus, 1st Century: Sick people, sometimes in a febrile paroxysm, lose their judgment and talk incoherently when the violence of the fit is abated, the judgment presently returns From Edward Marcantonio lecture: Delirium: What is it, and what do we (not) know about it. Presented at Delirium in Older Adults: Finding Order in the Disorder, February 9-11, 2014, Bethesda, MD 4

5 Synonyms: on the wards Agitated Bonkers Combative Crazy Lethargic Out of it Out to lunch Poor historian Seeing things Sleepy Uncooperative Wild man From Edward Marcantonio lecture: Delirium: What is it, and what do we (not) know about it. Presented at Delirium in Older Adults: Finding Order in the Disorder, February 9-11, 2014, Bethesda, MD 5

6 Delirium is a syndrome of many names.. Standardizing language is the first step in its appropriate management. From Edward Marcantonio lecture: Delirium: What is it, and what do we (not) know about it. Presented at Delirium in Older Adults: Finding Order in the Disorder, February 9-11, 2014, Bethesda, MD 6

7 Delirium Rates Hospital Prevalence (on admission) 14-24% Incidence (in hospital) 6-56% Postoperative: 15-53% Intensive Care unit: 70-87% Nursing Home/Post Acute care: 20-60% Palliative Care: up to 80% Hospital Mortality: 22-76% One Year Mortality: 35-40%» Inouye SK,NEJM 2006;354: Lancet 2013 online. 7 7

8 Delirium Consequences 10 fold increased risk of death in hospital Post-op complications Increased LOS Functional decline New NH placement Increased cost Distress for family patient and staff From Edward Marcantonio lecture: Delirium: What is it, and what do we (not) know about it. Presented at Delirium in Older Adults: Finding Order in the Disorder, February 9-11, 2014, Bethesda, MD 8

9 CAM Delirium Evaluation Patient Interview: Symptoms: confusion, perceptual disturbances Cognitive testing: orientation, attention Interviewer observations: Altered level of consciousness Psychomotor agitation, retardation Family/caregiver: time course, acuity CAM: puts it all together to make a diagnosis From Edward Marcantonio lecture: Delirium: What is it, and what do we (not) know about it. Presented at Delirium in Older Adults: Finding Order in the Disorder, February 9-11, 2014, Bethesda, MD 9

10 Delirium Diagnosis Delirium is a clinical diagnosis The Confusion Assessment Method (CAM) Sensitivity 94%-100% Specificity 90%-95% Hyperactive Delirium Restlessness / Agitation Hypoactive Delirium Slowed movement, unresponsive From Edward Marcantonio lecture: Delirium: What is it, and what do we (not) know about it. Presented at Delirium in Older Adults: Finding Order in the Disorder, February 9-11, 2014, Bethesda, MD 10

11 Confusion Assessment Method Feature 1 Acute onset and fluctuating course Feature 2 Inattention Feature 3 Disorganized thinking Feature 4 Altered consciousness Diagnosis of delirium requires features 1 and 2, and either 3 or 4 11

12 Testing Attention One of the most basic, but neglected areas of the mental status exam. Recommended methods: Digit span: 5 forwards, 4 backwards Days of week, months of year backwards Vigilance A task: HAVEAHEART From Edward Marcantonio lecture: Delirium: What is it, and what do we (not) know about it.

Targeted Neuroimaging R/O CVA Electroencephalogram R/O Seizures Address acute medical illness Drug adjustments (opioids, sedatives, hypnotics, anticholinergics) 16

17 Delirium Management Nonpharmacologic measures are first line in the symptomatic treatment of delirium. frequent orientation presence of family at the bedside maintaining the sleep-wake cycle Minimizing nighttime interruptions. Ensuring patient is awake and situated in a bright room during daytime. 16

18 Delirium Management Non-pharmacologic interventions. Avoid physical restraints Assessment of drugs and reduce psychoactive drugs. Encourage mobility and self cares Let patient know their schedule and keep them involved in their care Communicate regularly with patients and their families. Ensure patients have glasses, hearing aids and dentures» Inouye SK,NEJM 2006;354: Lancet

19 Delirium Management Pharmacologic interventions Reserve pharmacologic approaches for patients with severe agitation who risk interruption of essential medical treatment (eg, intubation) Self injury Have severe distressing psychotic symptoms (eg, hallucinations, delusions) NO EVIDENCE-LACK OF DATA to support this practice. Antipsychotics or sedating drugs can switch delirium from hyperactive to hypoactive, resulting in worse clinical outcomes Consider other approaches- non-pharmacologic 17 Aurora Health 15 Care, Inc.

20 Delirium Management Pharmacologic interventions For acute agitation and aggression that impairs care or safety. Haloperidol is the most often recommended and studied agent If QTc exceeds 500, do not administer any antipsychotic; all may prolong QTc Quetiapine is the drug of choice for patient with LBD, PD Benzodiazepines (alcohol or benzodiazepine withdrawal). 17 Aurora Health 15 Care, Inc.

22 HELP Program: 18 17

23 Hospital Elder Life Program (HELP) An evidence base medicine program developed by Sharon Inouye, MD. Designed to decrease delirium and functional decline in hospitalized older adults. This program is a prevention strategy. 19

24 HELP Evidenced based delirium prevention model. Statistically significant reduction in the onset of delirium. Research validated replication in multiple clinical settings. Cost-effective method for improving outcomes. 20

25 Goals of HELP Prevent unplanned readmissions. To maximize independence at discharge. To assist with the transitions from hospital to home. To maintain physical and cognitive. functioning throughout the hospitalization. 21

26 HELP - Hospital Elder Life St. Luke s Medical Center St Luke's is the largest acute care hospital in Wisconsin with 600+ beds and 27 nursing units. This model of care has been integrated into the Acute Care for Elders model. HELP uses skilled interdisciplinary staff and trained volunteers. HELP directs trained and supervised hospital volunteers to initiate specific prevention protocols to seniors identified by the ACE Tracker software program. 22

33 Could we integrate the HELP program into existing models of care and software systems? 29

34 ACE Tracker to Identify Older Patients who are at Risk for Delirium: Patient 1 Patient 2 Patient 3 Patient 4 Patient 5 Patient 6 Patient 7 Patient 8 29

35 Delirium Markers: ACE Tracker Nursing assessment for delirium symptoms. Fluctuating cognition/ Change in mental status/ attention/ thought process/ level of consciousness Any physical restraint in the prior 48 hours. Any antipsychotic medication in the prior 48 hours: Haloperidol Risperidone Quetiapine Olanzapine 30

37 Automated Prevalence of Delirium Rate among all Older Patients: 32

38 HELP Program Outcomes- Aurora St. Luke s Medical Center: What is the progress to date in implementing the HELP program? Between May 1, 2013 and February 28, 2014 the HELP program enrolled 528 older patients. Trained volunteers provided 1644 supervised visits to patients enrolled in the program. About 8 delirium prevention protocols deployed per patient. 33

39 HELP Program Outcomes- Aurora St. Luke s Medical Center: What percent of those who are eligible for the HELP program actually receive the care? We studied 97 older patients who were eligible for the HELP program on four nursing units from March 17, 2014 to March 21, were enrolled in the program. 34 were not assessed. 30 were not eligible for HELP program. 13 already had delirium. 7 refused the HELP program. 5 too highly functioning. 5 end stage disease/ end of life care. 34

40 HELP Program Outcomes- Aurora St. Luke s Medical Center: Between January 1, 2014 and February 28, 2014, we compared HELP program patients (n= 152) from four HELP nursing units to HELP eligible patients on the same units, who were not enrolled (n= 501): HELP program delirium symptoms rate= 5/152 patients, 3.3%. Non- enrolled HELP eligible delirium symptom rate: 26/501 patients, 5.2%. Improved length of hospital stay. Number needed to treat to avoid one case of delirium: about 50. Length of Stay Usual care group = 6.44 days HELP treatment group = 5.49 days Quality improvement data from Aurora Health Care,

41 Delirium quality measures for nine med- surgical nursing units at six Aurora hospitals from September 29 through October 28, 2013: Location: Patient days from through : Days of Delirium per 100 patient days: Hospital A- unit Hospital B- unit Hospital C HELP program Hospital C control group Hospital D- unit Hospital E- unit Hospital E- unit Hospital E- unit Hospital F Neurology unit

42 Delirium Outcomes at the nursing unit: We used a daily ACE Tracker report to assess the rate of delirium marker for all older patients from September 29, 2013 to October 28, Delirium rate on HELP program at Acute Care for Elders unit at St Luke s: 10.1 delirium days per 100 patient days. Delirium rate on Acute Care for Elders unit at Aurora West Allis: 14.1 delirium days per 100 patient days

43 Take Home Message: The HELP program can be successfully implemented in a large, tertiary care hospital. The electronic health record can be: programmed to automate the identification of older patients who are at risk of developing delirium. used to assist in the automated measurement of delirium in a large hospital. The identification of those at risk for delirium throughout a large health system may allow for broad implementation of delirium prevention- patient safety programs. 36

44 Can we integrate HELP into the Acute Care for Elders model of care? Acute Care for Elders: prevent functional decline and decrease the chance of new nursing home placement. Hospital Elder Life Program: prevent new onset of delirium and prevent functional decline. Integrating the two models of care: ACE Tracker. Advisory committees. Hospital and health system leadership. 37

48 Scaling up for the Health System and State: 807,164 older Medicare beneficiaries in Wisconsin. 193,470 hospital discharges of older Medicare patients in ,210 total hospital days in acute care/ 58 critical access hospitals in Wisconsin. Decrease the rate of new delirium from 15% to 10%: Across Aurora Health Care- avoid 1500 new cases of delirium per year. Across Wisconsin- avoid 10,000 new cases of delirium per year. Delirium $60,000 incremental costs per patient over subsequent 12 months. If HELP delirium prevention strategies were deployed: Across Aurora Health Care the potential savings: $90 million per year in health care costs. Across Wisconsin, the potential savings: $600 million per year in health care costs. Kaiser Family Foundation statehealthfacts.org KFF Compare Medicare Data 41

49 Ten Points in Scaling Up a Geriatrics Model of Care: 1. Carefully track outcomes. Baseline and comparison groups. 2. Define the business plan/ the economic impact of the model for the hospital. 3. Making sure stakeholders are clear about goals and the resources required. 4. Develop a timeline and a strategy for expansion. 5. Have appropriate staffing. 6. Integrate the model into the electronic health record. 7. Monitor and maintain fidelity of the model. 8. Provide a annual report to the hospital and health system. 9. Work with national leaders who can advise the project. 10. Include a patient on your advisory team- stay patient-centered. 42

50 A Vision to Spread HELP in Wisconsin: 1. Define state- wide stakeholders who have a interest in delirium prevention. 1. Wisconsin Hospital Association. 2. The Alzheimer's Association. 3. The Wisconsin Medical Society. 4. The Department of Health and Human Services. 5. Patient safety collaboratives. 2. Measure the rate of delirium among older patients in Wisconsin hospitals. 3. Use public health strategies to deploy delirium prevention strategies. 43
