Quantitative sensory testing (QST) is the standardized assessment of the somatosensory system comprising all sensory submodalities. In the German Research Network on Neuropathic Pain (DFNS), a QST-battery consisting of 13 parameters has been established and nationwide normative data have been collected. In contrast to conventional electrophysiology, QST allows detecting negative and positive sensory signs of both large and small fiber systems. ⋯ To facilitate more widespread use of QST, the German Pain Society (DGSS) and the DFNS have initiated a certification procedure for QST quality standards. Therefore, structural, procedural criteria and outcome parameters were establishd and are hereby presented. By maintaining high quality standards, the certification of QST is intended to contribute to a better understanding of the mechanisms behind neuropathic pain syndromes and thereby improve patient care as well as sensory assessment in clinical studies on the treatment of neuropathic pain syndromes.

Benzodiazepines are often used in palliative care for symptom control, for example in treatment of dyspnea or anxiety. They are also used for palliative sedation, if symptoms are not controlled (fast) enough and a reduction of consciousness is therefore necessary. Incidence of palliative sedation has been reported to vary between 5-52% of all patients in a palliative care setting in several studies. ⋯ The majority of patients had been treated with benzodiazepines whereas only very few had received deep and continuous sedation.
