We conducted a large nationwide postal survey to estimate the prevalence of chronic pain with or without neuropathic characteristics in the French general population. A questionnaire aimed at identifying chronic pain (defined as daily pain for at least 3 months), evaluating its intensity, duration and body locations, was sent to a representative sample of 30,155 subjects. The DN4 questionnaire was...
This study investigated the natural course of neck pain (NP) in 9–12-year-olds during a 4-year follow-up. Risk factors for the occurrence and persistence of weekly NP were explored separately for boys and girls. At baseline, 1756 schoolchildren completed a questionnaire eliciting musculoskeletal pain symptoms, other physical, and psychological symptoms and frequency of physical activity, and were...
Incidence rate estimates of neuropathic pain are scanty and mostly address single types whereas the scope of the disease is wide. We aimed to calculate the incidence rates of neuropathic pain conditions in the Dutch general population and to assess treatment strategies in primary care. The study population included persons registered for at least one year in the Integrated Primary Care Information...
Chronic pain has been traditionally defined by pain duration, but this approach has limited empirical support and does not account for chronic pain’s multi-dimensionality. This study compared duration-based and prospective approaches to defining chronic pain in terms of their ability to predict future pain course and outcomes for primary care patients with three common pain conditions: back pain (n=971),...
This report describes the prevalence of opioid use in the US adult population, overall and in subgroups, the characteristics of opioid use, and concomitant medication use among opioid users. Data were obtained from the Slone Survey, a population-based random-digit dialing survey. One household member was randomly selected to answer a series of questions regarding all medications taken during the previous...
Knowledge concerning the medical history prior to the onset of complex regional pain syndrome (CRPS) might provide insight into its risk factors and potential underlying disease mechanisms. To evaluate prior to CRPS medical conditions, a case–control study was conducted in the Integrated Primary Care Information (IPCI) project, a general practice (GP) database in the Netherlands. CRPS patients were...
A prognostic approach to defining chronic pain has been proposed as an alternative to traditional definitions based on retrospective duration of pain. While this new approach performs well in low back pain (LBP), headache and orofacial pain, it is not known whether it translates to regional pain syndromes with an underlying pathological component, such as osteoarthritis (OA). We investigated the performance...
Chronic pain is a public health problem with high impact on various population segments. There are few population studies with the aim of delineating the profile of the chronic pain patient, and generating data for actions to prevent, control and minimize the problem. The aim of this study was to estimate the prevalence of chronic pain in the population of Salvador, Bahia, Brazil and identify independent...
