The overall aim of the study is to investigate the time difference in the diagnosing of anemia among elderly with hip fracture, between measurements with standard blood samples and non-invasive SpHb-measuring. Another aim is to investigate the relationship between perfusion index and prolong perioperative anemia and the potential impact on perioperative complications.
Immediately after admission and diagnosis of a hip fracture the patients will be monitored with Masimo SpHb. The Patients will be continuously measured until the third day after surgery. The Monitors Hb and PI data but not the SpO2% will be blinded to all participating healthcare personnel.The first three postopertive days the patiens will daily be examined to determined it they have developed delirium. All perioperativ complications in that period will be monitored.

Delay in diagnosting perioperative anemia
Description of lag time between detection of anaemia by SpHb and Hb by blood sampling/transfusion
Time frame: From admission up to and including the 3 postopertive day
Perfusion index, periopertive anemia and delirium
The relation between average perioperative perfusion index, cumulated perioperative anemia over time and patient outcome in the form of medical complications, mortality, delirium and LOS.
Time frame: From admission up to and including the 3 postopertive day
Perfusion index as a predictor of early warning score (EWS)
Is there a relationship between low perfusion index an high EWS?
Time frame: From admission up to and including the 3 postopertive day
