THE MYTHS OF AGING • Sick, demented, frail, weak, disabled, powerless, sexless, passive, alone, unhappy • Holding back society • Scientific reality or not?
MYTH # 1TO BE OLD IS TO BE SICK Are the new seniors very sick/old or healthier? Past: Infectious illnesses Mid century: Arthritis, HTN, heart disease Now: Decrease prevalence arthritis, HTN, stroke, lung disease Compression of morbidity; less institutionalized 1994: 39% over 65 health very good or excellent with 29% fair or poor
MYTH #2YOU CAN’T TEACH AN OLD DOG NEW TRICKS • Fear of developing Alzheimer’s disease • Even those with short term memory problems have been shown to improve recall • Deficits can be overcome with proper training (lists, etc.)
MYTH #3 THE HORSE IS OUT OF THE BARN • Risky behaviors – no point in changing • Not too late for no smoking, exercise and diet
MYTH #4THE SECRET TO SUCCESSFUL AGING IS TO CHOOSE YOUR PARENTS WISELY • Is the role of genetics overstated? • Increased longevity of offspring of those who died at much earlier ages
MYTH #5THE LIGHTS MAY BE ON BUT THE VOLTAGE IS LOW • Inadequate physical/mental/sexual abilities • Sexual activity decreases in old age
MYTH #6THE ELDERLY DON’T PULL THEIR OWN WEIGHT • One third of elderly continue to work • One third of elderly volunteer • Others provide informal caregiving • Many more are willing and able to work
SUCCESSFUL AGING* • Low probability of disease and disease related disability • High cognitive and functional capacity • Active engagement with LIFE *Rowe and Kahn, Gerontologist, 1997
HEALTH • WHO: More than absence of disease • WHO: Presence of physical, mental and social well being; perceived in the context of each individual’s experiences, beliefs, and expectations. • Can 2 individuals with same objective measures of health status have different perceptions of health related quality of life?
GERIATRIC RX • Functionally oriented biopsychosocial model fostering comprehensive, multidimensional approach to health assessment • Context of patient’s beliefs and values • Must elicit values of patients to determine benefits and burdens of interventions
ELEMENTS OF ASSESSMENTS • Biomedical: acute/chronic diseases, physical function, ADLs, IADLs • Psychological: Intellect. function, personality, mood, sensorium, psych history/symptoms • Social: Family structure/involvement, friends, co-workers, neighbors, church, community, work history, financial resources, health insurance, living arrangements, life-style • Values: Personal, cultural, ethnic, religious, spiritual
PRINCIPLES OF GERIATRIC ASSESSMENT Goal Promote wellness, independence Focus Function, performance Scope Physical, cognitive, psychol, social Approach Multidisciplinary Efficiency Perform rapid screens to identify target areas Success Maintaining/improving quality of life
STEPS TO ESTABLISH GOALS OF HEALTH CARE FOR ELDERLY • Use biopsychosocial-values model to develop functionally oriented comprehensive health assessment • Develop all feasible options for care with benefits/burdens/risks and projected outcomes. • Acknowledge uncertainty where present • Relieve suffering • Communicate effectively to patients and significant others; become patient advocate
PHYSICIAN ROLE “The physician who enters the patient’s universe and understands the patient’s perceptions, assumptions, values and beliefs is a tremendous advantage.” Peabody, 1927 Care of the Patient, JAMA “It is therapeutic for the patient to feel that the physician cares enough about the individual to understand his life, particularly the meaning and purpose of his present existence.” Frankl 1959 (Man’s Search for Meaning)
