What are the 10 principles of geriatric medicine?
1 - Ageing itself is not a disease
2 - Geriatric conditions are chronic, multiple and multifactoral
3 - Reversible conditions are underdiagnosed and underTx
4 - Function + QOL are critical outcomes
5 - Social support and patient preferences = critical outcomes
6 - Geriatrics is MDT
7 - Cognitive and affective disorders are prevalent + freq underdiagnosed at early stages
8 - Iatrogenic disease = more common + preventable
9 - Care = provided in multiple settings
10 - Ethical and end of life issues
