As frailty can be addressed by care based on CGA it is important to detect frailty, but also to avoid the use of a complex CGA when not needed. A recent review have shown that frail elderly benefits more of CGA than a more mixed population of elderly. There is unfortunately no easy and overall accepted instrument to detect frailty. In research the criteria developed by Fried have been most frequently used - but is resource-demanding and seldom used outside academic research. Another more easy accessible method have been developed by Rockwood and have been chosen from the The International Consortium for Health Outcomes Measurement (ICHOM) as the preferred instrument to detect and measure frailty. The instrument is not well known in clinical practise in Sweden, why it could be interesting to test whether it applicable in Swedish Health Care.
