Assessing persistent pain and its relation to affective distress, depressive symptoms, and pain catastrophizing in patients with chronic wounds: a pilot study

OBJECTIVE: The purpose of this study was to examine pain experience among patients with chronic wounds, assess the utility of pain assessment scales for chronic wound-related pain, and determine the relation of wound-related pain to wound stage, affective distress, depressive symptoms, and pain catastrophizing. DESIGN: In this cross-sectional study of patients with a mix of chronic wounds (n = 69) recruited for a study evaluating a telemedicine system for assessing chronic wounds, 19 men (12 with spinal cord injury) with wound-related pain were identified. Questionnaires included the Numerical Pain Rating Scale, McGill Pain Questionnaire, Brief Symptom Inventory, Center for Epidemiologic Studies Depression Scale, and the catastrophizing scale of the Coping Strategies Questionnaire. RESULTS: The McGill Pain Questionnaire was more sensitive to pain experience than a single rating of pain intensity. Wound stage was positively related to severity of pain. Pain catastrophizing was positively related to pain intensity and higher levels of affective distress and depressive symptoms. CONCLUSIONS: Pain associated with chronic wounds is a significant clinical challenge for both patients and health practitioners.     

Impact of Bifrontal Home-Based Transcranial Direct Current Stimulation in Pain Catastrophizing and Disability due to Pain in Fibromyalgia: A Randomized,Double-Blind Sham-Controlled Study

This randomized, double-blind trial tested the hypothesis that 20 sessions of home-based anodal(a)-transcranial direct current stimulation (tDCS) (2mA for 20 minutes) bifrontal, with anodal on the left dorsolateral prefrontal cortex (l-DLPFC) would be better than sham-(s)-tDCS to reduce scores on Pain Catastrophizing Scale and disability-related to pain assessed by the Profile of Chronic Pain: Screen (primary outcomes). Secondary outcomes were depressive symptoms, sleep quality, heat pain threshold , heat pain tolerance , and serum brain-derived-neurotrophic-factor (BDNF). Forty-eight women with fibromyalgia, 30 to 65 years-old were randomized into 2:1 groups [a-tDCS (n = 32) or s-tDCS (n = 16)]. Post hoc analysis revealed that a-tDCS reduced the Pain Catastrophizing Scale total scores by 51.38% compared to 26.96% in s-tDCS, and a-tDCS reduced Profile of Chronic Pain: Screen total scores by 31.43% compared to 19.15% in s-tDCS. The a-tDCS improved depressive symptoms, sleep quality and increased the heat pain tolerance. The delta-value in the serum BDNF (mean post treatment end minus pretreatment) was conversely correlated with the a-tDCS effect in pain catastrophizing. In contrast, the a-tDCS impact on reducing the disability-related to pain at the treatment end was positively associated with a reduction in the serum BDNF and improvement of depressive symptoms, sleep quality and pain catastrophizing symptoms.PerspectiveHome-based bifrontal tDCS with a-tDCS on the l-DLPFC are associated with a moderate effect size (ES) in the following outcomes: 1) Decreased rumination and magnification of pain catastrophizing. 2) Improved the disability for daily activities due to fibromyalgia symptoms. Overall, these findings support the feasibility of self-applied home-based tDCS on DLPFC to improve fibromyalgia symptoms.     

Sativex successfully treats neuropathic pain characterised by allodynia: a randomised, double-blind, placebo-controlled clinical trial

Cannabinoids are known to have analgesic properties. We evaluated the effect of oro-mucosal sativex, (THC: CBD), an endocannabinoid system modulator, on pain and allodynia, in 125 patients with neuropathic pain of peripheral origin in a five-week, randomised, double-blind, placebo-controlled, parallel design trial. Patients remained on their existing stable analgesia. A self-titrating regimen was used to optimise drug administration. Sixty-three patients were randomised to receive sativex and 62 placebo. The mean reduction in pain intensity scores (primary outcome measure) was greater in patients receiving sativex than placebo (mean adjusted scores -1.48 points vs. -0.52 points on a 0-10 Numerical Rating Scale (p=0.004; 95% CI: -1.59, -0.32). Improvements in Neuropathic Pain Scale composite score (p=0.007), sleep NRS (p=0.001), dynamic allodynia (p=0.042), punctate allodynia (p=0.021), Pain Disability Index (p=0.003) and Patient's Global Impression of Change (p<0.001) were similarly greater on sativex vs. placebo. Sedative and gastrointestinal side effects were reported more commonly by patients on active medication. Of all participants, 18% on sativex and 3% on placebo withdrew during the study. An open-label extension study showed that the initial pain relief was maintained without dose escalation or toxicity for 52 weeks.     

Attributes of response in depressed patients switched to treatment with duloxetine

Background: This study was designed to assess clinical and functional outcomes associated with switching to duloxetine treatment in patients with major depressive disorder (MDD) experiencing emotional and painful physical symptoms in their current episode. Methods: In this 8‐week, multinational, multicentre, single‐arm, open‐label clinical trial, 242 MDD patients were switched to duloxetine 60 mg/day after selective serotonin reuptake inhibitor (SSRI) or serotonin and norepinephrine reuptake inhibitor (SNRI) treatment. The primary analysis compared mean change from baseline in Brief Pain Inventory – Modified Short Form (BPI‐SF) interference score between initial responders [≥ 50% reduction from baseline on the 17‐item Hamilton Depression Rating Scale (HAMD₁₇) Maier subscale] and initial non‐responders after 4 weeks. Initial responders continued with duloxetine 60 mg/day. Initial non‐responders received duloxetine 120 mg/day for the remaining 4 weeks. Depression, pain, anxiety and functional outcomes were also compared after 8 weeks. Results: BPI‐SF interference decreased from baseline in initial responders (n = 108) and initial non‐responders (n = 85) after 4 weeks of duloxetine treatment, with greater reductions in initial responders [BPI‐SF mean difference in reduction: 1.01 (95% CI 0.42–1.61); p < 0.001]. Reductions in pain interference favouring initial responders were also apparent after 8 weeks [0.68 (95% CI: 0.03–1.33); p = 0.042]. Depression, pain, anxiety and function improved over 8 weeks across patient groups. Conclusions: Elements of core mood and pain are important residual symptoms following poor treatment response in MDD. Early improvement in these symptoms after switching to duloxetine indicated an increased chance of functional recovery.

Patient Satisfaction in the Emergency Department—A Survey of Pediatric Patients and Their Parents

OBJECTIVES: To assess and compare overall satisfaction in pediatric emergency department (ED) patients and their accompanying parents. To identify aspects of health care delivery that influence satisfaction in these groups. METHODS: Pediatric patients (ages 5-17 years) and their parents (or guardians) seen at a university hospital pediatric ED were eligible. A convenience sample of English-speaking subject pairs (n = 101 pairs) was enrolled. Questionnaires were administered to both children and their parents at the completion of their ED care. The survey instruments used a modified Wong-Baker FACES Pain Rating Scale and a six-point interval scale. Factors measured included overall satisfaction, perceptions of pain and fear, and other characteristics of the ED visit. Data were analyzed using paired Wilcoxon signed-rank tests, Spearman rank correlation coefficients, and Fischer's exact chi-square tests (alpha = 0.05) where appropriate. RESULTS: Parent satisfaction was associated with the quality of provider-patient interactions (R = 0.54, p = 0.0001), the adequacy of information provided (R = 0.47, p = 0.0001), and shorter waiting room times (R = -0.24, p = 0.01). Child satisfaction was associated with the quality of provider-patient interactions (R = 0.24, p 0.04), adequacy of information provided (R = 0.51, p = 0.003), and resolution of pain (R = 0.25, p = 0.03). Parent estimates were similar to children's initial pain scores; however, children reported greater resolution of pain than appreciated by their parents (p = 0.006). CONCLUSIONS: Satisfaction can be validly and reliably measured in pediatric patients using a visual scale instrument. Factors that influence patient satisfaction were similar among both children and their parents. The influence of pain resolution on pediatric ED satisfaction is a novel finding, which demonstrates the importance of appropriate pain and anxiety assessment and treatment in children.     

The intensity of pain in the prehospital setting is most strongly reflected in the respiratory rate among physiological parameters

BackgroundIn order to treat pain optimally, the Emergency Medical Service (EMS) clinician needs to be able to make a reasonable estimation of the severity of the pain. It is hypothesised that various physiological parameters will change as a response to pain.AimIn a cohort of patients who were seen by EMS clinicians, to relate the patients' estimated intensity of pain to various physiological parameters.MethodsPatients who called for EMS due to pain in a part of western Sweden were included. The intensity of pain was assessed according to the visual analogue scale (VAS) or the Numerical Rating Scale (NRS). The following were assessed the same time as pain on EMS arrival: heart rate, systolic and diastolic blood pressure, respiratory rate, moist skin and paleness.ResultsIn all, 19,908 patients (≥18 years), were studied (51% women). There were significant associations between intensity of pain and the respiratory rate (r = 0.198; p < 0.0001), heart rate (r = 0.037; p < 0.0001), systolic blood pressure (r = ?0.029; p < 0.0001), moist skin (r = 0.143; p < 0.0001) and paleness (r = 0.171; p < 0.0001). The strongest association was found with respiratory rate among patients aged 18–64 years (r = 0.258; p < 0.0001).ConclusionIn the prehospital setting, there were significant but weak correlations between intensity of pain and physiological parameters.The most clinically relevant association was found with an increased respiratory rate and presence of pale and moist skin among patients aged < 65 years. Among younger patients, respiratory rate may support in the clinical evaluation of pain.     

Sensory,psychological, and metabolic dysfunction in HIV-associated peripheral neuropathy: A cross-sectional deep profiling study

HIV-associated sensory neuropathy (HIV-SN) is a frequent complication of HIV infection and a major source of morbidity. A cross-sectional deep profiling study examining HIV-SN was conducted in people living with HIV in a high resource setting using a battery of measures which included the following: parameters of pain and sensory symptoms (7 day pain diary, Neuropathic Pain Symptom Inventory [NPSI] and Brief Pain Inventory [BPI]), sensory innervation (structured neurological examination, quantitative sensory testing [QST] and intraepidermal nerve fibre density [IENFD]), psychological state (Pain Anxiety Symptoms Scale-20 [PASS-20], Depression Anxiety and Positive Outlook Scale [DAPOS], and Pain Catastrophizing Scale [PCS], insomnia (Insomnia Severity Index [ISI]), and quality of life (Short Form (36) Health Survey [SF-36]). The diagnostic utility of the Brief Peripheral Neuropathy Screen (BPNS), Utah Early Neuropathy Scale (UENS), and Toronto Clinical Scoring System (TCSS) were evaluated. Thirty-six healthy volunteers and 66 HIV infected participants were recruited. A novel triumvirate case definition for HIV-SN was used that required 2 out of 3 of the following: 2 or more abnormal QST findings, reduced IENFD, and signs of a peripheral neuropathy on a structured neurological examination. Of those with HIV, 42% fulfilled the case definition for HIV-SN (n = 28), of whom 75% (n = 21) reported pain. The most frequent QST abnormalities in HIV-SN were loss of function in mechanical and vibration detection. Structured clinical examination was superior to QST or IENFD in HIV-SN diagnosis. HIV-SN participants had higher plasma triglyceride, concentrations depression, anxiety and catastrophizing scores, and prevalence of insomnia than HIV participants without HIV-SN.

Comparison of traditional Chinese acupuncture, minimal acupuncture at non-acupoints and conventional treatment for chronic sinusitis

OBJECTIVES: To compare traditional Chinese acupuncture, minimal acupuncture at non-acupoints and conventional treatment for chronic sinusitis. DESIGN: A three-armed single blind randomised controlled study. SETTING: In an outpatient specialist clinic, we recruited 65 patients with symptoms of sinusitis >3 months and signs of sinusitis on computed tomography (CT). INTERVENTIONS: We randomised patients to one of three study arms: (1) 2-4 weeks of medication with antibiotics, corticosteroids, 0.9% sodium chloride solution, and local decongestants (n=21), (2) 10 treatments with traditional Chinese acupuncture (n=25), or (3) 10 treatments with minimal acupuncture at non-acupoints (n=19). OUTCOME MEASURES: Change in sinus soft tissue swelling on CT, symptoms of sinusitis, and health-related quality of life (HRQoL), using the two component summary scales of the Short Form 36 and a rating scale. RESULTS: In the conventional treatment group, sinus soft tissue swelling was reduced over 4 weeks (p=0.04), and HRQoL improved over 12 weeks (p=0.01-0.05). Pairwise comparisons of changes in total symptom score between the groups showed signs of a difference between conventional medication and sham over 4 weeks (p=0.06). CONCLUSION: Sinus soft tissue swelling was reduced in the conventional treatment group over 4 weeks, and HRQoL improved over 12 weeks. Only a non-significant difference in symptom score change over 4 and 12 weeks was shown between conventional medication and traditional Chinese acupuncture.     

Catastrophizing: a risk factor for postsurgical pain

OBJECTIVE: This research was designed to test the hypothesis that presurgery "catastrophizing" would predict postsurgical pain and postsurgical analgesic consumption. METHODS: A sample of 48 individuals who underwent anterior cruciate ligament repair participated in the study. All participants completed the Pain Catastrophizing Scale (described by Sullivan et al in 1995) prior to surgery. Measures of pain (pain scores on a scale of 0-10) were obtained in the postanesthetic care unit, as well as 1, 2, and 7 days after surgery. Opioid and nonopioid analgesic consumption was tabulated while patients were in the hospital and after discharge. RESULTS: Results showed that the Pain Catastrophizing Scale was a significant predictor of acute postsurgical pain in the postanesthetic care unit (r = 0.48, P = 0.004 for maximum pain in the postanesthetic care unit). Maximum pain ratings in patients with high Pain Catastrophizing Scale scores (> median of 13) were 33% to 74% higher numerically than in patients with low Pain Catastrophizing Scale scores (< or = median), and the duration of moderate-severe pain (>3/10) was more prolonged (45 minutes versus 28 minutes in patients with high and low Pain Catastrophizing Scale scores, respectively; P < 0.05). The Pain Catastrophizing Scale was also predictive of pain with activity at 24 hours (r = 0.65 for pain on walking, P < or = 0.0001). The Pain Catastrophizing Scale did not predict postoperative analgesic use. CONCLUSION: The pattern of findings suggests that high catastrophizing scores may be a risk factor for heightened pain following surgery. Clinical and theoretical implications of the findings are addressed.     

Effectiveness of an extension-oriented treatment approach in a subgroup of subjects with low back pain: a randomized clinical trial

BACKGROUND AND PURPOSE: The purpose of this multicenter randomized clinical trial was to examine the effectiveness of an extension-oriented treatment approach (EOTA) in a subgroup of subjects with low back pain (LBP) who were hypothesized to benefit from the treatment compared with similar subjects who received a lumbar spine strengthening exercise program. METHODS: Subjects with LBP and symptoms distal to the buttocks that centralized with extension movements were included. Forty-eight subjects were randomly assigned to groups that received an EOTA (n=26) or a strengthening exercise program (n=22). Subjects attended 8 physical therapy sessions and completed a home exercise program. Follow-up data were obtained at 1 week, 4 weeks, and 6 months after randomization. Primary outcome measures were disability (modified Oswestry Low Back Pain Disability Questionnaire) and pain (Numeric Pain Rating Scale). RESULTS: Subjects in the EOTA group experienced greater improvements in disability compared with subjects who received trunk strengthening exercises at 1 week (mean difference between groups from baseline=8.9, 95% confidence interval [CI]=2.0, 15.9), 4 weeks, (mean difference=14.4, 95% CI=4.8, 23.9), and 6 months (mean difference=14.6, 95% CI=4.6, 24.6). The EOTA group demonstrated greater change in pain at the 1-week follow-up only. DISCUSSION AND CONCLUSION: An EOTA was more effective than trunk strengthening exercise in a subgroup of subjects hypothesized to benefit from this treatment approach. Additional research is needed to explore whether an EOTA may benefit other subgroups of patients.     

Ten sessions of adjunctive left prefrontal rTMS significantly reduces fibromyalgia pain: A randomized, controlled pilot study

Transcranial magnetic stimulation (TMS) of the prefrontal cortex can cause changes in acute pain perception. Several weeks of daily left prefrontal TMS has been shown to treat depression. We recruited 20 patients with fibromyalgia, defined by American College of Rheumatology criteria, and randomized them to receive 4000 pulses at 10 Hz TMS (n = 10), or sham TMS (n = 10) treatment for 10 sessions over 2 weeks along with their standard medications, which were fixed and stable for at least 4 weeks before starting sessions. Subjects recorded daily pain, mood, and activity. Blinded raters assessed pain, mood, functional status, and tender points weekly with the Brief Pain Inventory, Hamilton Depression Rating Scale, and Fibromyalgia Impact Questionnaire. No statistically significant differences between groups were observed. Patients who received active TMS had a mean 29% (statistically significant) reduction in pain symptoms in comparison to their baseline pain. Sham TMS participants had a 4% nonsignificant change in daily pain from their baseline pain. At 2 weeks after treatment, there was a significant improvement in depression symptoms in the active group compared to baseline. Pain reduction preceded antidepressant effects. TMS was well tolerated, with few side effects. Further studies that address study limitations are needed to determine whether daily prefrontal TMS may be an effective, durable, and clinically useful treatment for fibromyalgia symptoms.     

A prospective,open‐label,multicentre study of pregabalin in the treatment of neuropathic pain in Latin America

Aims: The objective of this study was to evaluate the safety and efficacy of pregabalin at flexible doses of 150–600 mg/day in Latin American patients with neuropathic pain. Methods: A prospective, multicentre, open‐label, non‐comparative study included patients age ≥ 18 years diagnosed with neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, chemotherapy‐induced peripheral neuropathic pain (PNP), or human immunodeficiency virus‐related PNP. Eligible patients (N = 121) had a score of ≥ 40 mm on the visual analogue scale and a daily pain rating scale (DPRS) score of ≥ 4 throughout screening. Patients received flexible‐dose pregabalin (150–600 mg/day) for 12 weeks, which included a 4‐week dose‐adjustment phase. The primary efficacy measure was change from baseline to end of treatment/last observation carried forward (EOT/LOCF) in weekly mean pain score on the DPRS. Secondary efficacy measures included pain, anxiety, sleep interference, treatment satisfaction and Patient and Clinician Global Impression of Change. Results: Pregabalin significantly reduced the weekly mean pain score on DPRS from baseline to EOT/LOCF [–3.8 (95% CI: ?4.2 to ?3.3); p < 0.0001]. Reductions from baseline to EOT/LOCF were observed for all secondary efficacy outcomes (p < 0.0001). Pain and sleep interference were significantly improved compared with baseline across all weeks of the study, as early as 1 week after initiation of pregabalin (p < 0.0001). The most common adverse events (AEs) were somnolence, dizziness, weight gain and peripheral oedema. Nine (7.4%) patients discontinued the study because of AEs and 25 (20.7%) temporarily stopped or reduced their pregabalin dose because of AEs. Conclusions: Flexible‐dose pregabalin (150–600 mg/day) significantly reduced pain and anxiety and improved sleep and was generally well tolerated in Latin American patients with neuropathic pain.

Pain intensity measurement in chronic low back pain.

This study investigated the psychometric properties of eight pain intensity measures used with chronic low back pain patients. All measures were similar in terms of scale distribution and rates of incorrect responses, with all scales apart from the Pain Rating Index significantly correlated. Principal axis factoring of data from 92 patients indicated the presence of one general factor on which all pain intensity measures except the Pain Rating Index loaded. The 101-point Numeric Rating Scale and the Box Scale had the strongest relationship, with loadings of 0.90. The Numeric Rating Scale and the Box Scale appear to be the scales of choice for the measurement of pain intensity in the low back pain patient.     

Validation of the numerical rating scale for pain intensity and unpleasantness in pediatric acute postoperative pain: sensitivity to change over time

This study evaluates the construct validity (including sensitivity to change) of the numerical rating scale (NRS) for pain intensity (I) and unpleasantness (U) and participant pain scale preferences in children/adolescents with acute postoperative pain. Eighty-three children aged 8 to 18 years (mean = 13.8, SD = 2.4) completed 3 pain scales including NRS, Verbal Rating Scale (VRS), and faces scales (Faces Pain Scale-Revised [FPS-R] and Facial Affective Scale [FAS], respectively) for pain intensity (I) and unpleasantness (U) 48 to 72 hours after major surgery, and the NRS, VRS and Functional Disability Index (FDI) 2 weeks after surgery. As predicted, the NRSI correlated highly with the VRSI and FPS-R and the NRSU correlated highly with the VRSU and FAS 48 to 72 hours after surgery. The FDI correlated moderately with the NRS at both time points. Scores on the NRSI and NRSU at 48 to 72 hours were significantly higher than at 2 weeks after surgery. Children found the faces scales the easiest to use while the VRS was liked the least and was the hardest to use. The NRS has adequate evidence of construct validity including sensitivity for both pain intensity and unpleasantness. This study further supports the validity of the NRS as a tool to measure both intensity and unpleasantness of acute pain in children. PERSPECTIVE: This article evaluates the construct validity including sensitivity of the Numerical Rating Scale for pain intensity and pain unpleasantness over time in children after major surgery. The NRS could be used by clinicians to assess these 2 different dimensions of children's pain experience in acute pain settings.     

Pain in older persons with severe dementia. Psychometric properties of the Mobilization–Observation–Behaviour–Intensity–Dementia (MOBID‐2) Pain Scale in a clinical setting

Scand J Caring Sci; 2010; 24; 380–391
Pain in older persons with severe dementia. Psychometric properties of the Mobilization–Observation–Behaviour–Intensity–Dementia (MOBID‐2) Pain Scale in a clinical setting Background: To assess pain in older persons with severe dementia is a challenge due to reduced self‐report capacity. Recently, the development and psychometric property testing of the Mobilization–Observation–Behaviour–Intensity–Dementia (MOBID) Pain Scale was described using video‐recording. The purpose of this article was to present the further development of this instrument. In MOBID‐2 Pain Scale, the assessment of inferred pain intensity is based on patient’s pain behaviours in connection with standardized, guided movements of different body parts (Part 1). In addition, MOBID‐2 includes the observation of pain behaviours related to internal organs, head and skin registered on pain drawings and monitored over time (Part 2). Objective: The aim of this study was to examine psychometric properties of the MOBID‐2 Pain Scale, like inter‐rater and test–retest reliability, internal consistency, as well as face‐, construct‐ and concurrent validity. Subjects and Setting: Patients with severe dementia (n = 77) were examined by 28 primary caregivers in clinical practice, who concurrently and independently completed the MOBID‐2 Pain Scale. Characteristics of the patients’ pain were also investigated by their physicians (n = 4). Results: Prevalence of any pain was 81%, with predominance to the musculoskeletal system, highly associated with the MOBID‐2 overall pain score (rho = 0.82). Most frequent and painful were mobilizing legs. Pain in pelvis and/or genital organs was frequently observed. Moderate to excellent agreement was demonstrated for behaviours and pain drawings (κ = 0.41–0.90 and κ = 0.46–0.93). Inter‐rater and test–retest reliability for pain intensity was very good, ICC (1, 1) ranging 0.80–0.94 and 0.60–0.94. Internal consistency was highly satisfactory; Cronbach’s α ranging 0.82–0.84. Face‐, construct‐ and concurrent validity was good. Overall pain intensity by MOBID‐2 was well correlated with physicians’ clinical examination and defined pain variables (rho = 0.41–0.64). Conclusion: On the basis of pain behaviours, standardized movements and pain drawings, MOBID‐2 Pain Scale was shown to be sufficiently reliable, valid and time‐effective for nurses to assess pain in patients with severe dementia.
