PAIN2.0: study protocol for a multicentre randomised controlled trial to evaluate the efficacy of a 10-week outpatient interdisciplinary multimodal pain therapy to manage recurrent pain for patients with risk factors of developing chronic pain in Germany.

Background: Up to 27% of the German population suffers from recurrent or persistent pain (lasting more than three months). Therefore, prevention of chronic pain is one major object of pain management interventions. The aim of this nationwide, multicentre, randomised controlled trial is to evaluate the efficacy of a 10-week ambulatory (outpatient) interdisciplinary multimodal pain therapy (A-IMPT) for patients with recurrent pain and at risk of developing chronic pain.

[Development of two outpatient interdisciplinary group modules in the treatment of patients with pain and risk of chronification].

Background And Objective: An early treatment of patients who suffer from pain and show risk factors for chronification is meaningful as these patients can benefit from an early interdisciplinary multimodal pain treatment (IMST). In view of the insufficient treatment, two outpatient treatment modules for the secondary prevention of pain chronification are developed within the framework of PAIN2020: the educative and accompanying IMST (E‑IMST and B‑IMST).

Material And Methods: The developmental process of both IMSTs is presented.

[Second opinion on spine surgery : Indication rarely confirmed and conservative treatment options are worthwhile].

Background: Second opinion (SO) on spine surgery was recently implemented as a statutory right in Germany. Prior to this, one health insurer did offer SO to its policy holders including advice on additional conservative treatment options.

Objectives: Which treatment recommendations did 522 patients receive in an interdisciplinary multimodal assessment (IMA) as part of a SO by 4 teams comprising physician, physio- and psychotherapist and what were the long-term consequences?

Methods: Second opinions under a selective contract between insurer and back pain centers were evaluated based on patient-related anamnesis and interdisciplinary multimodal clinical findings including treatment recommendations and patient reports after about 2 years.

[Less surgery and lower cost due to back pain in a care program with an interdisciplinary second opinion procedure : A controlled non-randomized intervention study based on claims data].

Background: There is no evidence of effectiveness for interdisciplinary second opinion procedures (ISOP) for recommended back surgery (BS). Since 2015, AOK Nordost has been offering the care program RückenSPEZIAL comprising a preliminary examination, ISOP, and optional interdisciplinary multimodal pain therapy (IMPT). The objective of this study is to determine the effectiveness of RückenSPEZIAL to reduce BS and back pain-related costs (BPRC) compared to patients who likewise received a recommendation for back surgery but not RückenSPEZIAL.

[Characteristic values and test statistical goodness of the Veterans RAND 12-Item Health Survey (VR-12) in patients with chronic pain : An evaluation based on the KEDOQ pain dataset].

The Veterans RAND 12-Item Health Survey (VR-12) was added to the German Pain Questionnaire (DSF) as a self-report measure of health-related quality of life in 2016, replacing the previously used SF-12, which required a license. Both measures have 12 items and include a physical component summary (PCS) and a mental component summary (MCS). Evaluations with a larger sample on characteristic values and on the test-statistical goodness of the VR-12 in patients with chronic pain are so far missing.
