The Osteoporosis Risk Assessment Instrument (ORAI)

 

Patient selection: Canadian women aged >= 45 years of age (osteoporosis has a prevalence < 1% in women < 45 years)

 

Exclusion criteria: women with a diagnosis of osteoporosis or taking bone active medications other than estrogen-progesterone (calcitonin, biphosphonates, fluoride).

 

Parameters:

(1) age in years

(2) weight in kilograms

(3) current estrogen use

Parameter	Finding	Points
age in years	>= 75	15
	65 – 74	9
	55 – 64	5
	45 - 54	0
weight in kilograms	< 60	9
	60 – 69	3

ORIA score =

= (SUM(points for all 3 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 26

• Bone densitometry should be done if the woman has a total score >= 9.

 

Performance:

• The sensitivity was 93.3% and specificity 46.4% for identifying Canadian women with low bone density. The sensitivity was 94.4% for women with osteoporosis.
