[Comprehensive geriatric assessment--its clinical, social and economic importance and prospects].

It is well known that many elderly patients are referred to nursing homes because of "functional decline" without being thoroughly investigated. We studied 9 elderly patients, all referred to hospital due to functional decline and diagnosed as follows: spinal stenosis--2 cases, depression--3, thyrotoxicosis--1, Parkinson--1, polypharmacy and congestive heart failure--1 patient each. Proper diagnosis and appropriate treatment prevent unnecessary hospitalization in nursing homes. Our study is meant to draw attention to this crucial aspect of geriatric medicine.
