Randomized Controlled TrialIlioinguinal/Iliohypogastric versus quadratus lumborum nerve blockade for elective open inguinal herniorrhaphy: a prospective, randomized, double-blinded, equivalency trial.
Open inguinal herniorrhaphy (OIH) is a commonly performed surgical procedure with expected postoperative pain. Historically, an option for regional analgesia has been an ilioinguinal and iliohypogastric nerve block (IINB). More recently, the transmuscular quadratus lumborum block (QLB) has been used as an analgesic technique for a variety of abdominal and truncal surgical procedures. Given our own institutional experiences with the performance of QLB combined with the body of literature supporting the proximal blockade of the ilioinguinal and iliohypogastric nerves via this approach, we compared the analgesia provided by an IINB to a QLB. We hypothesized that the two blocks would provide equivalent analgesia, as defined by a difference of less than±2 points on the pain scale (0-10 numeric rating scale (NRS)), for patients undergoing OIH. ⋯ An IINB and a transmuscular QLB are equivalent with regards to their ability to provide postoperative analgesia after OIH.

ReviewIs the minimal clinically important difference (MCID) in acute pain a good measure of analgesic efficacy in regional anesthesia?
In the field of acute pain medicine research, we believe there is an unmet need to incorporate patient related outcome measures that move beyond reporting pain scores and opioid consumption. The term "minimal clinically important difference" (MCID) defines the clinical benefit of an intervention as perceived by the patient, as opposed to a mathematically determined statistically significant difference that may not necessarily be clinically significant. The present article reviews the concept of MCID in acute postoperative pain research, addresses potential pitfalls in MCID determination and questions the clinical validity of extrapolating MCID determined from chronic pain and non-surgical pain studies to the acute postoperative pain setting. We further suggest the concepts of minimal clinically important improvement, substantial clinical benefit and patient acceptable symptom state should also represent aspirational outcomes for future research in acute postoperative pain management.

To test the association between self-reported opioid disposal education and self-reported disposal of leftover opioids among older adults. ⋯ In this nationally representative survey, 49% had leftover opioids, yet only 20% of older adults reported disposal of leftover opioids. Opioid disposal education was variable in delivery, but was associated with disposal behaviors among certain populations. Strategies to promote disposal should integrate patient education on the risks of leftover opioid medications and explore additional barriers to accessing opioid disposal methods.

Accessing care in multidisciplinary pain treatment facilities continues to be a challenge in Canada.
Multidisciplinary pain treatment facilities (MPTFs) are considered the optimal settings for the management of chronic pain (CP). This study aimed (1) to determine the distribution of MPTFs across Canada, (2) to document time to access and types of services, and (3) to compare the results to those obtained in 2005-2006. ⋯ Accessibility to public MPTFs continues to be limited in Canada, resulting in lengthy wait times for a first appointment. Community-based MPTFs and virtual care initiatives to distribute pain services into regional and remote communities are needed to provide patients with CP with optimal care.
