Sernbo Score for Evaluating an Older Adult with a Hip Fracture

Description

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

Parameter	Finding	Points
age in years	70 to 79 years of age	5
	>= 80 years of age	2
social situation	independent (does not require caregivers)	5
	dependent and requires nursing or residential care	2
mobility	walks unaided or with one cane	5
	walks with 2 sticks or frame	2
	needs wheel chair or bed-bound	2
mental status	normal	5
	history of dementia	2

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.

Score	Arthroplasty	Mortality
8 to 14	hemiarthroplasty	high
15 to 20	total arthroplasty	low

Score	30-Day Mortality	1-Year Mortality
8 to 14	11%	35%
15 to 20	1%	8%

Performance:

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