Osteoarthritis of the knee clinical care standard indicators: 2b-Proportion of patients clinically diagnosed with knee osteoarthritis, without imaging
Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||Indicator 2b-Proportion of patients clinically diagnosed with knee osteoarthritis, without imaging|
|Registration status:||Health, Standard 02/08/2017|
Proportion of patients clinically diagnosed with knee osteoarthritis, without imaging.
There is a weak association between symptoms of knee osteoarthritis (including pain and disability) and imaging findings (Bedson & Croft 2008; Fernandes et al. 2013; Guermazi et al. 2012; Kinds et al. 2011; Thorstensson 2009). Findings from imaging results may not have any impact on treatment goals or influence the treatment plan; decisions will be more likely based on other considerations, such as the patient’s level of pain (Bedson & Croft 2008).
|Indicator set:||Clinical care standard indicators: osteoarthritis of the knee Health, Standard 02/08/2017|
Collection and usage attributes
|Population group age from:|
For the numerator, imaging includes X-rays, magnetic resonance imaging, computerised tomography and ultrasound.
Both the numerator and denominator include patients presenting with knee pain, stiffness and/or swelling and other symptoms suggestive of knee osteoarthritis, and who are then clinically diagnosed with knee osteoarthritis.
Both the numerator and the denominator exclude patients for whom:
Presented as a percentage.
(Numerator ÷ denominator) x 100
Number of patients clinically diagnosed with knee osteoarthritis, without imaging being undertaken.
Number of patients who are clinically diagnosed with knee osteoarthritis.
This indicator has been adapted from the Osteoarthritis quality standard (NICE 2015).
|Unit of measure:||Service event|
|Other issues caveats:|
Applicable setting: all healthcare settings where care is provided to patients with knee osteoarthritis, including primary care, specialist care, hospitals and community settings.
