The diagnostic power of PoCLUS is still under-evaluated in many settings and there is a generalized yet unjustified feeling that further evidence is needed before introducing PoCLUS as a standard of care. In the effort to build up further evidence by new studies, the role of randomized clinical trials is over-emphasized and gold standards used to investigate diagnostic accuracy of PoCLUS are sometimes not appropriate. Moreover, the sonographic patterns and techniques used to confirm the diagnoses not always are adapted to the patients' clinical condition, which limit the scientific value of those clinical studies.
