Understanding chronic pain and disability requires a consideration of the lived experience of the patient. There is limited evaluation of the content validity of patient-reported outcome measures (PROMs) in chronic pain using a comprehensive biopsychosocial view of the patient's experience. To address this gap, this study aimed to evaluate the content validity of PROMs for patients with chronic pain. ⋯ The greatest number of items across PROMs were represented in the activities and participation category (44% of all total items), followed by body functions (41%), environmental factors (9%), personal factors (5%), and body structures (0.3%). There was a 41% to 78% match with the Core Set for Chronic Widespread Pain and the International Classification of Diseases-11 FP, respectively. 20% of items reflected the pain-experience attributes with the most items reflecting the concept of "control over pain." Content validity analysis suggests chronic widespread pain patient-reported outcome measures poorly address attributes of living with chronic pain that matter most to patients. Future development or refinement should consider a more comprehensive view of the patients' lived experience.

Ectopic discharge ("ectopia") in damaged afferent axons is a major contributor to chronic neuropathic pain. Clinical opinion discourages surgical resection of nerves proximal to the original injury site for fear of resurgence of ectopia and exacerbated pain. We tested this concept in a well-established animal neuroma model. ⋯ Similarly, we saw no indication of resurgent ectopia originating in axotomized dorsal root ganglion neuronal somata and no behavioral reflection of resurgence. In summary, we failed to validate the concern that proximal resection of a problematic nerve would lead to intense resurgent ectopic discharge and pain. As the well-entrenched concept of resurgence is based more on case reports and anecdotes than on solid evidence, it may be justified to relax the stricture against resecting neuromas as a therapeutic strategy, at least within the framework of controlled clinical trials.

Pain is common in chronic pancreatitis (CP) and profoundly reduces quality of life (QoL). Multiple underlying mechanisms contribute to a heterogenous pain experience and reduce efficacy of pain management. This study was designed to characterize the distribution of mechanism-based pain phenotypes in painful CP. ⋯ Other factors, including pain medication use and healthcare utilization, did not differ between groups based on pain type. Subjects in the Both group had significantly worse health and QoL scores relative to those with nociceptive-only pain, suggesting that using psychosocial pain surveys may be useful for understanding pain subtypes in patients with CP. Additional research is needed to identify biochemical and biophysical signatures that may associate with and predict responses to mechanism-specific interventions.

Improving neurosurgical quality metrics necessitates the analysis of patient safety indicator (PSI) 04, a measure of failure to rescue (FTR). ⋯ In total, 65.7% of patients were inappropriately flagged as meeting PSI 04 criteria. PSI 04 currently identifies patients with complications unrelated to operating room procedures. Improvement in patient safety within neurosurgery necessitates the development of a subspecialty specific measure to capture FTR.

ReviewHelmet noninvasive ventilation in acute hypoxic respiratory failure.
Invasive mechanical ventilation is a lifesaving intervention for patients with severe acute hypoxic respiratory failure (AHRF), but it is associated with neuromuscular, cognitive, and infectious complications. Noninvasive ventilation (NIV) may provide sufficient respiratory support without these complications. The helmet interface for NIV could address concerns raised for the use of NIV as first-line therapy in AHRF. This review will summarize and appraise the current evidence for helmet NIV in AHRF. ⋯ There is limited evidence to support or refute the use of helmet NIV in AHRF. Further studies investigating the interface of helmet in NIV as a separate clinical entity are needed.
