After consensus definitions of HAND are agreed upon, a population within HAND to treat is identified, and primary outcome measures are defined, confounding and interacting elements must be further examined to gain a better understanding of the actual biological effect of the proposed adjuvant therapy.
Finally, as the ability to accurately calculate sensitivity and specificity for a test directly depends on the correct use of base rates [ 43], artificial manipulation of the base-rate impairment invalidates the standard definitions of HAND and results in an unreliable estimation of impairment in the sample.
The definitions of hand-hygiene opportunities, patient contact, and invasive procedures used for this analysis are consistent with APIC or CDC guidelines (Table 1).
If you're caught off guard by an abbreviation and can't find the definition on hand, asking these types of questions can help you figure out what the abbreviation stands for.
Radiographic hip OA was defined as "at least definite joint space narrowing", and no consensus was reached for the definition of radiographic hand OA.
They were turning out very sophisticated work with very simple tools — the definition of great hand skills.
Currently, there is no established gold standard for the definition of radiographic hand OA, and the studies also differ in regard to grading systems that are used and the definitions of radiographic hand OA [ 3].
Although the American College of Rheumatology criteria are the most frequently used definition of symptomatic hand OA for clinical studies, their limitations for epidemiological studies have been recognized [ 32].
Standardization of the definition of radiographic hand OA with respect to scoring methods, joints under evaluation, and the required number of affected joints could possibly reduce the variations across studies.
Inclusion criteria are: males and females; aged 50 years and over; fulfilling the American College of Rheumatology (ACR) definition of symptomatic hand osteoarthritis [ 27, 30], or symptomatic thumb base OA on clinical assessment; no other household member participating in the trial; ability to understand and capable of giving written informed consent.
