Clinical Scores of van Staa et al for Estimating the Risk of Fracture in a Post-Menopausal Woman: Other Bone Fractures

Description

Van Staa et al reported scores for predicting the long-term risk for fractures in post-menopausal women. One score predicts the risk for fractures in bones other than the femur and vertebrae. The authors are from multiple universities in The Netherlands, Belgium and England.

Patient selection: female >= 50 years of age

Outcome: 5-year and 10-year risk for fractures in bones other than femur and vertebrae

Parameters:

(1) age in years

(2) fracture history and age

(3) fall history and age

(4) body mass index (BMI) in kilograms per square meter

(5) smoker

(6) chronic disease

(7) recent use of CNS medication

Parameter	Finding	Points
age in years	50 to 59 years	0
	60 to 69 years	5
	70 to 79 years	9
	>= 80 years	12
fracture history and age	no	0
	yes and 50-59 years	8
	yes and 60 to 79 years	7
	yes and >= 80 years	6
fall history and age	no	0
	yes and 50 to 59 years	7
	yes and 60 to 79	5
	yes and >= 80 years	4
BMI	< 20 kg per square m	2
	20 to 25.9	0
	>= 26 kg per square m	-2
smoker	no	0
	yes	1
chronic disease	no	0
	yes without recent GP visit or hospitalization	1
	yes with recent GP visit or hospitalization	2
recent use of CNS drug	no	0
	yes	2

total score =

= SUM(points for all 7 parameters)

Interpretation:

• minimum score: -2

• maximum score: 34

• The higher the score the greater the risk.

Score	5-Year Risk
-2 to 30	(0.0002761 * ((score)^3)) + (0.003556 * ((score)^2)) + (0.2536 * (score)) + 2.009
> 30	> 17.3%

Score	10-Year Risk
-2 to 30	(0.0003016 * ((score)^3)) + (0.01136 * ((score)^2)) + (0.2884 * (score)) + 4.027
> 30	> 31%
