Sernbo et al reported a score for evaluating an older adult with a hip fracture. It can help to determine which arthroplasty may be better for a patient and to predict postoperative mortality. The authors are from Malmo University Hospital in Sweden.
Patient selection: age >= 70 with hip fracture
Parameters prior to the fracture:
(1) age in years
(2) social situation
(3) mobility
(4) mental status

total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 8
• maximum score: 20
• The higher the score the better the survival.
• The scores are not continuous. A score of 14 would be seen with 2 risk factors and a score of 17 with 3. So the score could be replaced by a risk factor count of 0 to 2 versus 3 or 4.

Performance:
• Dawe et al found that the score had a 92% sensitivity and 51% specificity for predicting death at 30 days.
