Guidance
4 Recommendations for further research
Diagnostic accuracy
4.1 The committee recommends more research on diagnostic accuracy in people with leg ulcers. The following considerations should be made when doing this research:
-
where the devices would be used in clinical practice and by who (specialist and non-specialist users; see section 3.11)
-
the most appropriate threshold for the automated measurement (see section 3.12); if an alternative threshold to the currently established threshold is being researched, then a prespecified threshold should be used and research should be done in a population not used to derive this threshold (external validation)
-
whether using additional outputs from other devices such as doppler waveform and pulse volume waveform impacts clinical decision making (see section 3.5).
