Observational Study
Changes in prevalence of prescription opioid abuse after introduction of an abuse-deterrent opioid formulation.
The reformulation of oxycodone hydrochloride controlled-release (CR) tablets in August 2010 created a natural experiment at a national scale, providing an opportunity to evaluate patterns of abuse of prescription opioids and other drugs before and after introduction of this abuse-deterrent formulation (ADF). ⋯ Replacement of a widely prescribed opioid formulation known for its abuse potential alone may have had little impact on overall rates of prescription opioids as a class. However, changes in abuse levels of certain opioids coinciding with ADF introduction suggest possible switching of abuse among this study sample to specific long-acting opioid analgesics. Additional follow-up studies will be important to monitor changing abuse patterns and their public health impact as new opioid formulations are developed and introduced to market.

A performance improvement continuing medical education (PI CME) activity was designed to assist clinicians with accurately identifying and appropriately managing persistent pain in long-term care facility (LTCF) residents. ⋯ This CME activity allowed for collection of data demonstrating performance improvement in persistent pain management. The tools used as part of the intervention (available at http://www.achlpicme.org/LTC/toolkit) may help other clinicians enhance their management of LTCF residents with persistent pain.

Observational Study
Tricyclic antidepressants: is your patient taking them? Observations on adherence and unreported use using prescriber-reported medication lists and urine drug testing.
Tricyclic antidepressants (TCAs) are first-line treatment for neuropathic pain. Despite widespread use, many health care providers do not know which patients are currently taking TCAs. The objective of this retrospective data analysis was to determine adherence rates to amitriptyline, nortriptyline, or imipramine. The rate at which patients used TCAs (confirmed by presence of TCA in the urine) but did not inform their health care provider is also reported (non-informed prescriber rate). Finally, the effects of age, sex, and number of prescriptions on adherence and non-informed prescriber rates were assessed. ⋯ This analysis reveals that many prescribers are not informed when patients start and stop using TCAs.

The aim of this study is to evaluate prospectively the efficacy of caudal epidural steroid injection (CESI) and transforaminal epidural steroid injection (TFESI) in lumbar spinal stenosis patients with sciatic pain. ⋯ The effectiveness of transforaminal steroid injection for the stenosis patients with sciatica was superior to caudal at 6 months postinjection.

Low back pain is a common cause of chronic pain in human immunodeficiency virus (HIV)-infected patients. The American College of Physicians and American Pain Society guidelines for diagnostic imaging in low back pain are difficult to apply to patients with chronic illnesses like HIV who may have risk factors for cancer or compression fractures, but whether imaging all such patients for low back pain improves outcomes is unknown. ⋯ This is the first study to explore the role of spinal imaging in HIV-infected patients. In our study, four patients had findings concerning for malignancy. These findings suggest that spinal imaging should be considered in the work up of HIV-infected patients with moderate to severe back pain.
