Pain management is a crucial issue for patients, and patients' perception of care is an important quality outcome criterion for health care institutions. Pain remains a common problem in hospitals, with subsequent deleterious effects on well-being. ⋯ Pain was both prevalent and severe in the hospital, but patient participation in decision making was related to better outcomes. Optimal pain management, with emphasis on patient participation in decision making, should be encouraged in an effort to improve the quality of care in hospitals.

Randomized Controlled Trial
Endogenous Pain Modulation in Response to Exercise in Patients with Rheumatoid Arthritis, Patients with Chronic Fatigue Syndrome and Comorbid Fibromyalgia, and Healthy Controls: A Double-Blind Randomized Controlled Trial.
Temporal summation (TS) of pain, conditioned pain modulation (CPM), and exercise-induced analgesia (EIA) are often investigated in chronic pain populations as an indicator for enhanced pain facilitation and impaired endogenous pain inhibition, respectively, but interactions are not yet clear both in healthy controls and in chronic pain patients. Therefore, the present double-blind randomized placebo-controlled study evaluates pains cores, TS, and CPM in response to exercise in healthy controls, patients with chronic fatigue syndrome and comorbid fibromyalgia (CFS/FM), and patients with rheumatoid arthritis (RA), both under placebo and paracetamol condition. ⋯ This study evaluates pain scores, TS, and CPM in response to submaximal exercise in 2 different chronic pain populations and healthy controls. In patients with RA, exercise had positive effects on TS, suggesting normal EIA. In patients with CFS/FM, these positive effects were only observed after paracetamol and results were inconsistent.

Persistence, the duration a patient remains on therapy, in chronic, symptomatic conditions plays an important role in therapy effectiveness. Understanding the duration and patient factors associated with prescribed medication persistence is, therefore, an important step toward better treatment and health outcomes for patients. In the following study, an analysis of such factors associated with buprenorphine transdermal system (BTDS) persistence was conducted utilizing a large US private practitioner and pharmacy claims database and is herein reported. ⋯ Prior and concomitant use of adjuvant analgesics, prior use of opioids, and dose adjustments were associated with significantly longer persistence among patients initiating BTDS. The results suggest that patients are less likely to discontinue BTDS early if practitioners account for prior treatment history and dose titration.

Randomized Controlled Trial
Subconscious Manipulation of Pain Expectation Can Modulate Cortical Nociceptive Processing.
To determine whether manipulation of the expectation of pain inhibition can enhance the efficacy of conditioned pain modulation in healthy participants ⋯ As perceived pain inhibition was enhanced but flexion reflex size unchanged following the intervention, we suggest that the intervention gave rise to an inhibition of ascending nociceptive information at a supraspinal level resulting in reduced pain perception without influencing spinal level processing of nociceptive input. The finding that conditioned pain modulation can be enhanced is of relevance to clinical pain populations who commonly show impaired inhibition.

The aim of this study was to investigate whether variations in the way that pain intensity is measured in patients with neck pain influences the magnitude of pain ratings. The study uses data from 3 longitudinal studies (n = 361 at baseline) on people with neck pain due to whiplash injuries. Pain measures included verbal rating scales, numerical rating scales and a visual analog scale. ⋯ It is likely the length of recall time (eg, pain today vs. average pain over 4 weeks) has a significant influence on pain ratings. The influence of number of response options is less certain. Systematic reviewers should not uncritically rescale and pool absolute pain scores from instruments with varying scale descriptors or recall periods.
