Randomized Controlled Trial Multicenter Study
The effectiveness of graded motor imagery for reducing phantom limb pain in amputees: a randomised controlled trial.
To investigate whether graded motor imagery (GMI) is effective for reducing phantom limb pain (PLP) in people who have undergone limb amputations. ⋯ (PACTR201701001979279).

Multicenter Study Clinical Trial
10 kHz SCS for chronic postsurgical pain: Results from a 12-month prospective, multicenter study.
Chronic postsurgical pain (CPSP) can be caused by peripheral nerve injury (PNI) resulting from surgical procedures and has a significant neuropathic component. This prospective, single-arm study was conducted to document the effectiveness of 10-kHz spinal cord stimulation (10-kHz SCS) as a treatment for patients with CPSP. ⋯ 10-kHz SCS is effective and tolerated in patients with CPSP, and further study of its clinical application in this population is warranted.

Loss of efficacy (LOE) is a well-known phenomenon associated with spinal cord stimulation (SCS) and is the leading cause of explant. Although recent advances in neuromodulation have resulted in a decreased incidence of LOE, it still occurs. Intuition suggests that when LOE ensues, switching to a different SCS therapy/platform could potentially be a viable clinical option; however, there are no data presently available to validate this theory. ⋯ LOE is an unfortunate occurrence with few evidence-based solutions presently available to reverse it. Our findings suggest that implementing D-Burst stimulation may be an effective option for treating LOE, as well as potentially reducing opioid consumption, regardless of the prior SCS system.

Multicenter Study
Sustained Long-Term Outcomes With Closed-Loop Spinal Cord Stimulation: 12-Month Results of the Prospective, Multicenter, Open-Label Avalon Study.
Spinal cord stimulation (SCS) activates the dorsal column fibers using electrical stimuli. Current SCS systems function in fixed-output mode, delivering the same stimulus regardless of spinal cord (SC) activation. ⋯ The majority of patients experienced more than 80% pain relief with stable SC activation, as measured by ECAP amplitude at 12 mo, providing evidence for the long-term effectiveness of the Evoke closed-loop SCS system.

Multicenter Study
A Multiyear Cross-sectional Study of Guideline Adherence for the Timeliness of Opioid Administration in Children With Sickle Cell Pain Crisis.
The National Heart, Lung, and Blood Institute evidence-based guidelines for timeliness of opioid administration for sickle cell disease (SCD) pain crises recommend an initial opioid within 1 hour of arrival, with subsequent dosing every 30 minutes until pain is controlled. No multisite studies have evaluated guideline adherence, to our knowledge. Our objective was to determine guideline adherence across a multicenter network. ⋯ Guideline adherence for timeliness of SCD treatment is poor, with half of visits adherent for time to first opioid and one seventh adherent for second dose. Dissemination and implementation research/quality improvement efforts are critical to improve care across EDs.
