Chronic pain is experienced by one in five Australians and is estimated to be the nation's third most costly health problem. In 2013, a chronic pain treatment outcomes registry was established, with the goals of evaluating treatment of chronic pain in multidisciplinary centers, establishing a benchmarking system to drive quality improvement and providing answers to important questions regarding types of treatment ("dose," intensity, and response) and which treatment is appropriate for different patients. This paper describes the development and the first-phase implementation of the registry. ⋯ The electronic Persistent Pain Outcomes Collaboration has been established for Australasia and is strongly supported by specialist societies and consumer groups. The next phase will increase the proportion of follow-up data in order to realize the registry's goals of evaluation, benchmarking, and research to improve outcomes and services for patients experiencing persistent pain.

The aim of this study was to assess whether the effectiveness of bisphosphonate infusion in patients with complex regional pain syndrome type I (CRPS-I) is influenced by variables related to patient and/or disease characteristics. ⋯ Early disease, fracture as a predisposing event, and "warm" disease subtype are predictors of responsiveness to bisphosphonate treatment in patients with CRPS-I.

Available modalities for the longitudinal capture and analysis of pain intensity in patients with sickle cell disease (SCD) limit our ability to study intraindividual and interindividual variation in pain and the factors influencing the transition from acute to chronic pain in patients with SCD. ⋯ The longitudinal collection of pain data with the inclusion of hospital data during periods of hospitalization is feasible and acceptable in patients with SCD over periods of 30 to 60 days. Long-term collection of pain diary data, while informative, is associated with higher rates of missing data. Novel metrics of pain have the potential to better describe intraindividual and interindividual variation in pain, inform studies of the transition from acute to chronic pain as well as contribute patient-reported end points of pain for interventional clinical trials of pain in SCD.

To identify patient-reported outcome (PRO) instruments that assess chronic low back pain (cLBP) symptoms (specifically pain qualities) and/or impacts for potential use in cLBP clinical trials to demonstrate treatment benefit and support labeling claims. ⋯ There is an unmet need for a validated PRO instrument to evaluate cLBP-related symptoms and impacts for use in clinical trials.

Complex regional pain syndrome (CRPS) is a persistent pain condition that remains incompletely understood and challenging to treat. Historically, a wide range of different outcome measures have been used to capture the multidimensional nature of CRPS. This has been a significant limiting factor in the advancement of our understanding of the mechanisms and management of CRPS. ⋯ The domains encompassing the key concepts necessary to answer the research question were agreed as follows: pain, disease severity, participation and physical function, emotional and psychological function, self-efficacy, catastrophizing, and patient's global impression of change. The final core measurement set included the optimum generic or condition-specific patient-reported questionnaire outcome measures, which captured the essence of each domain, and 1 clinician-reported outcome measure to capture the degree of severity of CRPS. The next step is to test the feasibility and acceptability of collecting outcome measure data using the core measurement set in the CRPS population internationally.
