13% of the U.S. population is currently over 65
By 2030 it is expected there will be 68 million Americans older than 65 or 20% of the population

In 1900 life expectancy was 47.3 years
By 1950 life expectancy was up to 68.2 years
2010 life expectancy was 78.7 years

Older women outnumber older men at 23.0 million older women to 17.5 million older men.
Current life expectancy for women is 81.1 years for men it is 76.2 years

At age 65 life expectancy is about 19 more years
At age 75 life expectancy is about 12 more years
At age 85 life expectancy is about 7 more years

The geriatric population is becoming more ethnically diverse in the U.S.
Currently the non-hispanic white are 73.6 % of the elderly but expected to decline to 60.5% by the year 2030
Increases in the Hispanic-American and Asian-American populations are expected

In the community 75% of men over 65 are likely to be married and living with their spouse
41% of women over 65 are married and living with their spouse
47% of women over 65 are widows13% of men over 65 are widowers

Half the price of a nursing home, but what services are you getting?
Liability is hurting development of the industry
Much less regulation than nursing homes right now

Age is not an accurate predictor of condition or function
Co-morbidities are commonPresentation of illness is altered
(non-specific)Homeostatic control is less efficient

The single best predictor of institutionalization is impaired functional status
Self-reported function is an accurate predictor of health risks and costs
23% of older adults report some functional limitation in either ADLs or IADLs much higher percentage for the oldest segments

Common presenting complaints should make alarms sound in your head to think comprehensively.
These presenting complaints are likely to have multifactorial causes including the effects of age-related changes and chronic disease mediated changes

Incidence is about 20% of those older than 65 and 50% of those older than 75
90% success with surgery (vision improved to at least 20/40)
Surgery is safe taking less than 30 minutes: breakdown of old lens, and new lens implant
About 15% of patients need addition laser capsulotomy after lens implant

Ask the listener preferred way to communicate with them
Obtain listener’s attention before speaking Eliminate background noise Make sure the listener can see your lips Speak slowly and clearly avoid shouting Speak to the better ear Change phrasing if listener doesn’t seem to
understand Spell, use gestures or write down words Ask the listener to repeat what they heard

Complications of falls are the leading cause of death from injury in adults over age 65
33% of adults over age 65 report falling within the past year
Most result in minor soft tissue injuries 10-15% result in fractures 5% result in more serious soft tissue injury
or head trauma Cost is considerable – ED visits, admission
