The Shifting Face of Health Care
From acute to chronic disease
From institutions to networks of care; from a single site (hospital, nursing home) to many sites: home, assisted living, supportive housing, physician’s office, community clinics, ambulatory care centers, community hospitals, academic health centers, rehabilitation facilities, nursing homes, palliative care centers
From a single professional, generally a physician to many health care professionals: family doctors, specialists, nurses, physical therapists, nutritionists, social workers, psychologists, etc.

Aging and Chronic DiseaseThe Challenge for the 21st Century
Dramatic increase in the number of old, in particular old/old
Increase in prevalence of chronic disease– 1 in 5 baby boomers will develop dementia– Cardiovascular: most important cause of hospital admission – Diabetes: increasing prevalence with age: 10% over 65– Cancer: increasing incidence and mortality with age

Aging and Chronic DiseaseThe Challenge for the 21st Century
Complex relationship – Increase in chronic diseases due to aging as a result
of longer exposure to chronic disease risk factors in a vulnerable population
– Cumulative impact of chronic disease throughout the life course contributes to frailty and ultimately disability and dependency
A global challenge– ↑ chronic diseases +↑ life expectancy = Aging with ↑
disability
![Page 7: Chronic Disease and Aging The 21 st Century Healthcare Challenge](https://reader035.fdocuments.in/reader035/viewer/2022062323/5681671b550346895ddb9418/html5/thumbnails/7.jpg)
Heath care systems and the challenge of aging
Potential for promotion/prevention promoting healthy aging and in at least delaying onset of frailty and disability
↑ complex interventions (technology/surgery/medication) in increasingly older persons
Health care systems poorly adapted to the management of chronic disease, frailty and dependency; complexity of treating chronic diseases and frail older persons

Implementation in a coherent system:
challenges to explorePopulation Health ApproachPrimary Care Reform
– The Family Medicine Group(GMF): basis for integration– Example of proposed Quebec Alzheimer Plan
• Collaborative care model ; Partnership MD-Nurse-Patient-caregiver; Nurse navigator
• Community social care (AD support centre)• Intensive team based case management and multidisciplinary
community based services• Role of specialty care• End of life care

Primary Care Medical Reform in Canada
GMF (Qc); Family Health Teams (Ont); Medical Home (College of family Physicians of Canada– May or may not be in the same building eg BC and
Alberta Group practice; interdisciplinary practice;
continuity of care with population and healthcare system responsibility; evolving remuneration; IT infrastructure: evolving integration of other healthcare professionals
![Page 20: Chronic Disease and Aging The 21 st Century Healthcare Challenge](https://reader035.fdocuments.in/reader035/viewer/2022062323/5681671b550346895ddb9418/html5/thumbnails/20.jpg)
Implementation of a service structure based on the chronic-care model and the collaborative-practice model, introduced gradually, starting in Family Medicine Groups (FMGs) and Network Clinics (NCs).
– The primary care physician and the nurse clinician responsible for continuity of patient services establish a partnership with each patient and his or her family for the process of assessment, diagnosis, treatment, monitoring, and follow-up.
• Approximately 10 to 15 patients with AD per MD = 100-150 per FMG with 10 MDs
– The nurse clinician plays the role of Alzheimer’s nurse care navigator.

Chronic Disease and Aging in the Acute Care Setting
↑ of chronic diseases– ↑ hospitalization– ↑ hospitalization for Ambulatory Case-Sensitive (ACS) conditions– ↑ hospitalization associated with avoidable and costly complication
> 65– 37% of admissions– 50% of hospital days– ↑ readmission
Siu et al: Health Affairs 2008
![Page 22: Chronic Disease and Aging The 21 st Century Healthcare Challenge](https://reader035.fdocuments.in/reader035/viewer/2022062323/5681671b550346895ddb9418/html5/thumbnails/22.jpg)
Change in profile ofhospitalized patients
Profile of patients on admission– demography/health promotion and prevention/medical
care– Treatment/intervention in ambulatory and primary
careIncreasingly complex medical and surgical
interventions on older and older patients
![Page 23: Chronic Disease and Aging The 21 st Century Healthcare Challenge](https://reader035.fdocuments.in/reader035/viewer/2022062323/5681671b550346895ddb9418/html5/thumbnails/23.jpg)
The Challenge of the Aging Population Frailest elderly ~3% of population are the major client
group, use 30% of health-care resources Seniors use 1/3 of all hospital admissions & 1/2 of
inpatient days (2002/2003 Hospital morbidity database) Readmission rates 42% in patients >75 years Seniors have higher rates of return visits to emergency Disconnect between patient needs and hospital practices
= “hostile environment” Frail elderly experience further functional decline not
related to acute episode but to hospital practices (Inouye et al 2000)
Adverse effects are higher in frail elderly even when adjusted for age/co-morbidity

The loss of independent functioning during hospitalization has been associated with:
(Inouye et al 2000)
Prolonged lengths of hospital stay Increased readmissionA greater risk of institutionalizationHigher mortality rates
Myth: Elderly patients with chronic diseases are blocking the system– It’s only an outflow problem
Disconnect between patient needs and hospital environment
![Page 28: Chronic Disease and Aging The 21 st Century Healthcare Challenge](https://reader035.fdocuments.in/reader035/viewer/2022062323/5681671b550346895ddb9418/html5/thumbnails/28.jpg)
An appropriate approach …60 years agoStructured to support continued action on single disease
strategies and approaches; disjuncture and repetition of activities
Based on reducing LOS of uncomplicated acute admissionsPatients too complex to fit into standard critical pathways and
treatment modelsThe complex patients (“acute on chronic”; functional decline;
decreased reserve with age) get lost: – ↑ LOS;↑ LTC; ↑ Readmissions
Siu et al: Health Affairs 2008: The ironic case for the chronic disease model in the acute care setting
![Page 29: Chronic Disease and Aging The 21 st Century Healthcare Challenge](https://reader035.fdocuments.in/reader035/viewer/2022062323/5681671b550346895ddb9418/html5/thumbnails/29.jpg)
The Acute Care settingRe-thinking the approach in a coherent system of care
Engagement with primary medical and community care: a collaborative care approach– Transition in and out of the hospital– Specialty care supporting primary care
• Not necessarily within the hospital
Engagement with LTC– Smooth transitions– Prevention of admissions

The Acute Care settingRe-thinking the approach in a coherent system of care
From the traditional medical and surgical wards to the collaborative care wards
Clinical processes and organization of care within the hospital– Interdisciplinary team directed care based on best practices– Integrate holistic older person evaluation within the acute care process– Physical organization– Hospital environment– Patient and family engagement
Training including end of life care

The Acute Care settingRe-thinking the approach: the key elements
Aggregating the 3 components in a coherent system– Pre-hospital– Intra Hospital– Post-hospital
Inter disciplinary rather than disciplinary
Partnership: clinicians, managers, the community
Research: a key component

The Chronic Disease Modelquestions and issues
Can the Chronic Disease Model be implemented without primary medical reform– Family Medicine Groups in Quebec
How can the Chronic disease(S) model be integrated into primary care
![Page 34: Chronic Disease and Aging The 21 st Century Healthcare Challenge](https://reader035.fdocuments.in/reader035/viewer/2022062323/5681671b550346895ddb9418/html5/thumbnails/34.jpg)
Beyond the ModelsReflections on key elements Primary care
What seems to work/needs to be tested Primary med care: org
infrastructure/remuneration The multi disciplinary care
integrated into primary medical care
Evolution of relationships among professionals
Rapid access to intensive professional services (professional and social); access to a wide range of assisted/supportive housing
Population data/ responsibility
What does not seem to work Primary med care: organization
/infrastructure/remuneration not suited to complex continuing care
The programmatic, budgetary and geographic cleavage between primary medical and multidisciplinary care
Parallel play among professionals Sporadic responsibility There are no emergencies
