Page 3 In what year did these statements appear in a health care administration publication? “The overwhelming needs of the aging population have led to increasing expenditures for hospital care….” “How this growing elderly population will obtain and pay for health care is emerging as a major social issue……” “This changing financial and demographic trend, coupled with the limited resources provided for the elderly population, has been called the “Geriatric Imperative”” Bachman et al, Hospital and Health Services Administration 32(4):

Is it just an age thing?

Page 13 Coordinating Person-Centered Elder Care Requires an Inter(Trans)disciplinary Team
Page 14 Types of Teams in Healthcare Uniprofessional: Group of people all from the same discipline working together Multiprofessional: Group of people from different disciplines who develop a treatment plan independently GITT Curriculum: Teams and Teamwork; Klarare A. et al, J Pall Med 2013;16(9): Transprofessional: Although roles are specialized, everyone is prepared to step in/replace each other when necessary; Team leadership varies with the situation – OK to get outside your lane a bit Interprofessional: Group of people from different disciplines assess and plan care in a collaborative manner
Page 15 Transprofessional “I have learned the importance of the effects of polypharmacy in the care and treatment of UAB's geriatric patients…….. A patient's life may be changed due to medications.” - UAB Trauma Unit Occupational Therapist, 2013
Page 16 Transprofessional “One of the best things I have learned was about the different routes and half-life of IV compared to po pain meds. Last week I was able to counsel a patient and her daughter on the benefits of transitioning off IV pain meds.” - UAB ACE Unit Social Worker, 2014

Acute Care for Elders (ACE) Units are a team model of coordinated geriatric care in the hospital setting originally designed to maintain patient functional status during hospitalization

Page 28 Cost Savings from ACE Model Variable Direct Cost Savings = $371/case ~ $371,000 savings in variable direct cost for every 1000 patients If UC patients experienced ACE model Number of patients age ≥ 65 discharged from ACE Unit
So how can the ACE model, originally designed to maintain patient functional status, possibly impact readmissions?
Page 30 Readmission Patterns for Older Adults with AMI, CHF, and Pneumonia Medicare claims data from to determine patterns Mean age of readmitted patients = 80 yrs for all DRGs studied Most readmits within first 15 days for all studied DRGs Dharmarajan et al, JAMA 2013;309(4):
Page 31 Study Authors’ Thoughts: “The broad range of acute conditions responsible for readmission may reflect post-hospitalization syndrome – a generalized vulnerability to illness among recently discharged patients, many of whom have developed new impairments both during and after hospitalization.” Losses in mobility/functional status, nutritional status, delirium, adverse drug events, etc. “The heightened vulnerability to a diversity of illnesses may explain why interventions that are broadly applicable to many conditions with multiple components or are delivered by a multidisciplinary team are more likely to reduce readmissions.” Dharmarajan et al, JAMA 2013;309(4): Aren’t these what ACE Units address?
Page 32 ACE Unit Models of Care Have Been Shown to: Improved functional performance at discharge Improved likelihood of living at home after discharge Reduced restraint use Reduced high-risk medication use Improved nutritional support during hospitalization Improved patient and provider satisfaction Reduced length of stay Reduced health care utilization costs Reduced 30-day readmissions Landefeld et al, N Engl J Med 1995; Counsell et al, JAGS 2000; Jayadevappa et al, Value in Health, 2006; Flood et al, Crit Rev Onc/Heme 2010; Flood, et al, Am J Geriatr Pharmacother 2009; Baztan et al, BMJ 2009; Flood et al, JAMA Int Med 2013.

Page 38 Virtual ACE Ortho Unit Staff Feedback “Before the ACE we had delirium cases so frequently, now cases have tremendously subsided.” “Getting them moving early on has increased their satisfaction with the care at UAB and makes their pain much better. Appetite improves too.” “Just the awareness of delirium prevention has opened our eyes to things we wouldn’t have noticed before. As a unit it seems everyone is working well together by implementing these initiatives. It’s easy to become complacent if you don’t know how to work effectively with a geriatric patient, but the ACE initiative has made us excited to make changes and actively see results.” “Toolbox is a great thing to have ”
