Investigating dose-dependent effects of placebo analgesia (PA) in laboratory subjects undergoing pain testing, we evaluated 2 hypotheses: (1) greater expectancy for relief produces greater PA, and (2) cued expectancy for relief triggered by a predictive cue leads to more enhanced analgesia than does passive expectancy (no predictive cue). We used conditioning procedures in which 84 subjects experienced reduced stimulation intensity following the application of purported analgesic creams to the 2 experimental fingers, while the control finger received the same levels of stimulation as in the baseline block. The dose of placebos was manipulated by creating 2 levels of expectations for relief. ⋯ Greater expectation for relief led to both (1) greater reductions in the average dependent variable slope (response sensitivity) as a function of stimulus intensity, and (2) greater reductions in average response magnitude. Unexpectedly, uncued expectation led to a slightly larger PA than did cued expectation. The study provided clear evidence that PA can occur in a "dose"-dependent manner, mediated by the levels of expectancy for pain relief.

Pain management is a major concern for patients contemplating total knee replacement surgery and is one of the leading causes of dissatisfaction after knee replacement. Substantial progress has been made over the past several years in improving pain control after total knee replacement using multimodal pain control, preemptive analgesia, and periarticular injections.

Engaging consumers living in remote areas of Western Australia in the self-management of back pain: a prospective cohort study.
In Western Australia (WA), health policy recommends encouraging the use of active self-management strategies as part of the co-care of consumers with persistent low back pain (LBP). As many areas in WA are geographically isolated and health services are limited, implementing this policy into practice is critical if health outcomes for consumers living in geographically-isolated areas are to be improved. ⋯ To sustain improved consumer beliefs regarding LBP and encourage the adoption of more positive health behaviours, additional reinforcement strategies for consumers living in remote areas where service access and skilled workforce are limited are recommended. This study highlights the need for aligning health services and skilled workforce to improve the delivery of co-care for consumers living in geographically isolated areas.

Multimodal pain management techniques using femoral and sciatic nerve blocks can dramatically improve a patient's experience after total knee arthroplasty. Nerve blocks reduce postoperative pain and the need for parenteral opioids and result in fewer medical complications associated with opioid use. ⋯ Although it is difficult to isolate the added benefit of sciatic nerve blocks, there is a growing body of evidence for using femoral and/or sciatic nerve blocks as part of a multimodal approach to pain management. With many years of experience and published results on thousands of patients, it is clear that the risks of peripheral nerve blocks are minimal, whereas the benefits are substantial.

Several investigators have identified an explosive increase in spinal injection rates in the Veterans Administration and Medicare populations. Furthermore, utilization of spinal injection procedures appears to vary by geographic location, subspecialty, and practice setting. Medicare claims analysis has shown that a small percentage of physicians perform a disproportionately large number of injections. Although Medicare utilization has been well characterized, the utilization patterns for privately insured individuals are not clearly known. ⋯ These findings demonstrate that relatively few providers are responsible for a disproportionately high percentage of interventional spine procedures. This pattern of marked overutilization by a minority of providers is the dominant characteristic of utilization within all specialties.
