Even though validation studies of the WHO analgesic ladder have indicated that the simple approach of the analgesic ladder can provide adequate pain control in most patients, prevalence studies have documented a high prevalence of pain in cancer patients. Little is known about how analgesics are actually prescribed for cancer pain. The aim of the study was to study prescriptions of analgesics during the entire disease trajectory in patients dying from cancer within five years of diagnosis. ⋯ Complete national data covering the complete disease trajectory in cancer patients dying within five years of diagnosis. The majority of patients do not receive treatment in concordance with the stepwise approach suggested by the WHO analgesic ladder.

Chronic postsurgical pain (CPSP) is a common complication after many surgical procedures, including cardiac surgery. The prevalence of CPSP after cardiac surgery ranges from 9.5% to 56%. Most studies on CPSP after cardiac surgery are retrospective and long-term prospective studies are scarce. The aim of this study was to follow CPSP and health-related quality of life (HRQOL) prospectively in a cohort of patients, emphasizing the prevalence from 12 months to 5 years. ⋯ The prevalence of chronic postsurgical pain (CPSP) at 5 years after surgery of 3.8% is lower than previously reported. The majority of patients reporting CPSP after 12 months did not report CPSP after 5 years.

No core set of measurement tools exists to collect data within clinical practice. Such data could be useful as reference data to guide treatment decisions and to compare patient characteristics or treatment results within specific treatment settings. ⋯ A detailed description of case complexity of patients with chronic pain referred for pain rehabilitation. Insight in case complexity of patients within subgroups on the basis of gender, pain duration, pain severity and pain location. These descriptions can be used as reference data for daily practice in the field of pain rehabilitation and can be used to evaluate, monitor and improve rehabilitation care in care settings nationwide as well as internationally.

Review Meta Analysis
Systematic review of patient history and physical examination to diagnose chronic low back pain originating from the facet joints.
Patient history and physical examination are frequently used procedures to diagnose chronic low back pain (CLBP) originating from the facet joints, although the diagnostic accuracy is controversial. The aim of this systematic review is to determine the diagnostic accuracy of patient history and/or physical examination to identify CLBP originating from the facet joints using diagnostic blocks as reference standard. We searched MEDLINE, EMBASE, CINAHL, Web of Science and the Cochrane Collaboration database from inception until June 2016. ⋯ Due to clinical heterogeneity, the evidence for the diagnostic accuracy of patient history and/or physical examination to identify facet joint pain is inconclusive. Patient history and physical examination cannot be used to limit the need of a diagnostic block. The validity of the diagnostic facet joint block should be studied, and high quality studies are required to confirm the results of single studies.

Randomized Controlled Trial Multicenter Study
Preferred frequencies and waveforms for spinal cord stimulation in patients with complex regional pain syndrome: A multicentre, double-blind, randomized and placebo-controlled crossover trial.
Conventional tonic spinal cord stimulation (SCS) is an effective treatment for patients with therapy-resistant complex regional pain syndrome (CRPS). Although the therapeutic effect of SCS can diminish over time due to tolerance, pain control can be regained by changing the pulse width and the amplitude and/or by increasing the stimulation frequency. This multicentre, double-blind, randomized and placebo-controlled crossover trial was conducted to investigate whether more effective pain reduction is achieved with different frequencies (trial registration, current controlled trials, ISRCTN 36655259). ⋯ This study demonstrates that standard frequency SCS is an effective therapy for patients with CRPS. However, it also demonstrates that patients can often gain better pain reduction with non-standard frequencies of SCS. Furthermore, it shows that the preferred stimulation setting is not solely driven by the amount of pain reduction, but is also influenced by which stimulation setting feels most comfortable and provides the best user-friendliness. Therefore, we strive to maximize the therapeutic effects of SCS in as many patients as possible. This can be achieved with customized individual patient care by incorporating the various frequencies and waveforms into one single device.
