In view of these limitations in sensitivity and specificity, contemporary guidelines recommend repeat testing for diagnostic certainty.
When talking about the influence on prescribing in hospital care, the following topics were most frequent: indication and disease (2), risk assessment in acute cases (2), specificity of guidelines (2) and time constraints during patient consultation (2).
We added four items from the topic list of Peters that were relevant for our target group: specificity of guideline recommendations, knowledge of physical therapists, skills of physical therapists, and required time investment for using the guideline.
Research into the positive predictive value of CRC symptoms in the UK population is ongoing [ 22] to improve the sensitivity and specificity of the Guidelines, although the revised TWR referral Guidelines by NICE [ 16], published in 2005, are almost identical to the original DoH Guidelines and so, are not likely to increase the proportion of CRC patients diagnosed using the TWR.
Therefore, it has to be evaluated for completeness, accuracy, clarity, specificity, adherence to guidelines and disease-based structure.
However, the low specificity of current guidelines of appropriateness substantially reduces the predictive value of relevant endoscopic findings.
Main outcome measures Sensitivity and specificity of WHO guidelines in diagnosing invasive bacterial disease; susceptibility of isolated organisms to recommended antimicrobials.
Due to a lack of specificity in the guidelines language, we interpreted the recommendations as suggesting that adults should exercise at least 5 days per week for at least 30 minutes, or ≥150 minutes of moderate and/or vigorous of physical activity per week [ 44].
In Germany, they were challenged in initiating an insulin therapy after failure of the treatment with oral anti-diabetics [ 35] and they lacked knowledge and skills regarding the appropriate and individualized treatment of the elderly (largely due to specificity in the guidelines regarding this group) [ 36].
In practice, however, several aspects of the guidelines lack specificity, are subject to varied interpretations, or fail to capture relevant aspects of clinical molecular genetics.
