The goal of this study was to determine the minimal change in pain score recognized by patients as meaningful known as minimal clinically important difference (MCID). ⋯ Recognizing the extent of change in pain score that really matters to patients is crucial for the evaluation of treatment effect. Patients perceived a change of 1.65 points on NRS and 16.55 on VAS in their pain severity as meaningful. This value was not different whether the pain was perceived alleviated or aggravated.

Comparative evaluations of single-item pain-intensity measures in cancer patients: Numeric rating scale vs. verbal rating scale.
To evaluate the psychometric quality of two single-item pain-intensity measures: the Numeric Rating Scale (NRS) and the Verbal Rating Scale (VRS). ⋯ Pain assessment is a vital role of nurses in caring for patients with cancer. Current study findings support the use of the single-item NRS pain measure to assess global pain intensity over the past week.

ReviewThirty-five Years of Acute Pain Services: Where Do We Go From Here?
Acute pain services (APS) have developed over the past 35 years. Originally implemented solely to care for patients with regional catheters or patient-controlled analgesia after surgery, APS have become providers of care throughout the perioperative period, with some institutions even taking the additional step toward providing outpatient services for patients with acute pain. Models vary considerably in terms of tasks and responsibilities, staffing, education, protocols, quality, and financing. ⋯ Development of APS in the future will require us to face urgent questions, such as, "What are meaningful outcome variables?" and, "How do we define high quality?" It is obvious that focusing exclusively on pain scores does not reflect the complexity of pain and recovery. A broader approach is needed-a common concept of surgical and anesthesiological services within a hospital (eg, procedure-specific patient pathways as indicated by the programs "enhanced recovery after surgery" or the "perioperative surgical home"), with patient-reported outcome measures as one central quality criterion. Pain-related functional impairment, treatment-induced side effects, speed of mobilization, as well as return to normal function and everyday activities are key.

Comparative Study
Analysis of count data in the setting of cervical cancer detection.
Women with an abnormal Pap smear are often referred to colposcopy, a procedure during which endocervical curettage (ECC) may be performed. ECC is a scraping of the endocervical canal lining. Our goal was to compare the performance of a naïve Poisson (NP) regression model with that of a zero-inflated Poisson (ZIP) model when identifying predictors of the number of distress/pain vocalizations made by women undergoing ECC. ⋯ ZIP was preferred over NP. ZIP performed better than NP regression. Clinicians and epidemiologists should consider using the ZIP model (or the zero-inflated negative binomial model) for zero-inflated count data.

Stability of Measures of Pain Catastrophizing and Widespread Pain Following Total Knee Replacement.
Pain catastrophizing and widespread pain are predictors of pain chronicity/severity. Gaps remain in our understanding of the extent to which each is a stable (trait) or dynamic (state) variable. We undertook this study to assess the stability of each variable from before to after total knee replacement (TKR) and whether changes are explained by pain improvements. ⋯ The PCS score reflects state-like aspects of catastrophizing that diminish along with pain. In contrast, widespread pain scores worsened and improved equally often, regardless of knee pain relief. The findings urge caution in interpreting PCS score and widespread pain as trait measures in musculoskeletal research.
