Review Meta Analysis
Health care practitioners' attitudes and beliefs about low back pain: a systematic search and critical review of available measurement tools.
The attitudes and beliefs that health care practitioners (HCPs) hold about back pain have been shown to affect the advice they provide to patients seeking healthcare. In order to develop a questionnaire for a national survey of attitudes, beliefs and practice behaviour of HCPs about back pain, a systematic review of available measurement tools was undertaken. Measurement tools were identified from a systematic search of databases (Medline, Embase, CINAHL, Psychinfo, AMED and British Nursing Index) in the English language for papers published from January 1990 to October 2006. ⋯ PT have undergone the most thorough testing to date, but gaps in the properties of all the tools remain, particularly test-retest reliability and responsiveness. This review identified only five tools and demonstrated limited reporting of their validity and reliability. Further development and testing of existing tools should be a priority to ensure they are robust and valid measures of attitudes and beliefs of HCPs about back pain.

Randomized Controlled Trial Multicenter Study
Spinal cord stimulation versus conventional medical management for neuropathic pain: a multicentre randomised controlled trial in patients with failed back surgery syndrome.
Patients with neuropathic pain secondary to failed back surgery syndrome (FBSS) typically experience persistent pain, disability, and reduced quality of life. We hypothesised that spinal cord stimulation (SCS) is an effective therapy in addition to conventional medical management (CMM) in this patient population. We randomised 100 FBSS patients with predominant leg pain of neuropathic radicular origin to receive spinal cord stimulation plus conventional medical management (SCS group) or conventional medical management alone (CMM group) for at least 6 months. ⋯ Between 6 and 12 months, 5 SCS patients crossed to CMM, and 32 CMM patients crossed to SCS. At 12 months, 27 SCS patients (32%) had experienced device-related complications. In selected patients with FBSS, SCS provides better pain relief and improves health-related quality of life and functional capacity compared with CMM alone.

Postherpetic neuralgia (PHN) is the most frequent complication of herpes zoster (HZ) and difficult to treat. Timely identification of high-risk HZ-patients enables physicians to focus on PHN prevention. To assess which simple to measure factors are independent predictors of PHN, and whether psychosocial and serological/virological parameters have additional predictive value, a prospective cohort study in primary care was conducted. ⋯ Of the five PCL scores, only factor V ('trust in healthcare') was an additional predictor (OR=1.01 per unit), though it increased the ROC area with only 0.01 to 0.78. The Spielberger's anxiety scores and serological and virological variables were no additional predictors. Thus, four simple variables can help physicians to timely identify elderly HZ-patients at risk of PHN.

Cancer-related pain in outpatient adult populations remains high and has a direct effect on functional status. Factors that affect functional status have been explored separately, but the inter-relatedness of those factors has not been examined. Using a cross-sectional design, the purpose of this study was to examine the relationships between pain level, beliefs about pain, symptom distress, perceived control over pain, and functional status in 304 ambulatory cancer patients who experienced cancer-related pain within the past 2 weeks. ⋯ Patients' perceived control over pain may be an important component in pain management. The direct and mediating effects of perceived control and symptom distress suggest areas of further research. Interventions to increase knowledge and decrease barriers to pain control have the potential for increasing perceived control over pain.
