Active clinical trials for "Chronic Pain"

The overall goal of the ABILITY study is to help improve pain diagnostics and treatment by developing an implementable clinical computerised decision support system based on individual patient characteristics. The investigators hypothesize that successful pain control with opioids can be predicted before treatment initiation with advanced data analyses of data originating from pre-treatment EEG, QST and pain-related catastrophic thinking. The primary objective of this study is the identification of markers that can be used to individualize treatment recommendations, i.e. to reliably predict the response of pain to opioids. Markers are selected among the most promising data and machine-learning methods are used for the prediction. This includes determining the associations between a battery of selected pre-treatment clinical predictive markers and the analgesic effect of opioid treatment in opioid naïve chronic pain patients, including indication and responder identification. The key secondary objectives are as follows: to investigate pre-treatment clinical predictive markers as predictors of opioid treatment efficacy and effectiveness in terms of the following: Pain intensity and unpleasantness Use of rescue analgesics Physical functioning Global improvement and satisfaction with treatment

Evaluation of pupillary reflex in patients on high-dose opioids. Clinical assessment of pain intensity, sedation score, and other side effects of opioids. Measurements of the concentration of opioids and their active metabolites in blood.

The purpose of this study is to determine the effect of opioid taper on pain sensitivity in patients with chronic pain. In a well-characterized sample of men and women with chronic neuropathic pain on high-dose opioid therapy, experimental pain responses (cold-pressor, quantitative sensory testing) will be serially described over the course of and following an individualized opioid taper. In addition, functional improvements and subject-level predictors of response will be described.

The World Health Organization's (WHO) understanding of health(care) is incrementally incorporating the spiritual dimensions equivalent to the physical, psychological and social ones. Yet, it remains widely neglected in multi-modal, interprofessional chronic pain therapy. To support gaining access to chronic pain patients' spiritual needs and concerns within therapy, a screening tool has been constructed based on foregoing qualitative research and literature. The screening tool is to be validated with chronic pain patients in clinical settings.

Background: Physiotherapists (PTs) in primary health care manage patients with a large variation in medical diagnosis, age, functional status, disability and prognosis. Lack of knowledge and systematically collected data about patients treated by PTs in primary health care has prompted this longitudinal observational physiotherapy project in Norway. This paper aims to describe a method for developing a database of patients managed by PTs in primary health care to study patients' characteristics, treatment courses and prognostic factors. The study is a longitudinal observational project, following patients through physiotherapy treatment periods in primary health care in Norway and until one year after inclusion. The project involves both private practice and municipally employed PTs working in primary health care in eight municipalities in Norway. The participants are recruited to three different parts of the project depending on age and whether they are referred to a private practice or a municipally employed PT. All data are recorded electronically, transferred and stored securely. All patients complete extensive questionnaires providing information about demographics, disability and function, pain related variables, treatment and evaluation of treatment as well as clinical tests. The PTs have access to their own patients' data. The investigators have also prepared for linkage to national patient registers and population-based studies to be able to gather further important data. This project will have important implications for physiotherapy services in primary health care. The database already contains almost 3000 patients, and data collection is ongoing. Preliminary analyses suggest that the patients included so far are representative of the larger population of patients treated by private practice or municipally employed PTs in Norway. This large scale prospective physiotherapy project will provide knowledge about the patient groups treated, treatment given as well as short and long term outcome of the patients.

Pain is a subjective feeling,and pain experts have been trying to assess it using objective methods. Pain index (PI) is extracted from electroencephalographic as an objective diagnostic tool for chronic pain. This study is a diagnostic test aims to explore the reliability and validity of PI, with numerical rating scale(NRS) as the gold standard.

Sacrifice of the intercostobrachial nerve (ICBN) during surgery is associated with development of persistent post-surgical pain (PPSP), which affects up to 60% of breast cancer surgery patients. A large, definitive trial is needed to establish whether nerve preservation techniques are effective in reducing post-surgical pain after breast cancer surgery. If the effect of ICBN preservation is consistent with observational studies, the absolute reduction of rates of persistent pain would be considerable.The primary objective is to determine the effect of ICBN preservation, versus usual care, on the prevalence and intensity of PPSP at one year after breast cancer surgery involving axillary lymph node dissection (ALND). Within the larger INSPIRE pilot, we will also be conducting a biomarker sub-study. The objectives of the biomarker sub-study are: 1) to determine the association between pro-inflammatory cytokine levels and the presence and intensity of persistent pain at 3 weeks, and 3 months post-surgery, and) 2) to determine the effect of study intervention on the change in cytokine levels (pre-operative to post-operative) in participants who consent to participate in the sub-study.

It is known that there is an association between smoking and acute/chronic pain. But it is so difficult to assess this relation with asking questions to the patients in the preoperative period. Because of that we want to measure the levels of the cotinine in the urine and later assess the correlation with acute and chronic pain in hysterectomy patients.

The primary objective of this study is to describe the administration practices of the antalgic Ketamine in French CLCC (Centre de Lutte Contre le Cancer) in terms of indication (neuropathic sequelae pains, morphine additional effect or morphine withdrawal, intensity, localisation…) and administration protocol (route, posology, duration, administration sequence, premedication). The secondary objectives are to evaluate in the context of cancer, the analgesic efficacy, the tolerance profile (biological and clinical toxicities) and the quality of life, including anxiety and depression. In addition, the described parameters will be evaluated as safety and efficacy predictive factors of the Ketamine in oncology.
