Evidence-based practice guidelines for interventional techniques in the management of chronic spinal pain are systematically developed and professionally derived statements and recommendations that assist both physicians and patients in making decisions about appropriate health care in the diagnosis and treatment of chronic or persistent pain. The guidelines were developed utilizing an evidence-based approach to increase patient access to treatment, to improve outcomes and appropriateness of care, and to optimize cost-effectiveness. All types of relevant and published evidence and consensus were utilized. ⋯ It is expected that a provider will establish a plan of care on a case-by-case basis, taking into account an individual patient's medical condition, personal needs, and preferences, and the physician's experience. Based on an individual patient's needs, treatment different from that outlined here could be warranted. These guidelines do not represent "standard of care."

Healthcare decisions are increasingly being made on research-based evidence, rather than on expert opinion or clinical experience alone. Consequently, the process by which the strength of scientific evidence is evaluated and developed by means of evidence-based medicine recommendations and guidelines has become crucial resulting in the past decade in unprecedented interest in evidence-based medicine and clinical practice guidelines. Systematic reviews, also known as evidence-based technology assessments, attempt to minimize bias by the comprehensiveness and reproducibility of the search for and selection of articles for review. ⋯ The complex processes of guideline development depend on integration of a number of activities, from collection and processing of scientific literature to evaluation of the evidence, development of evidence-based recommendations or guidelines and implementation and dissemination of the guidelines to relevant professionals and consumers. Guidelines are being designed to improve the quality of healthcare and decrease the use of unnecessary, ineffective or harmful interventions. This review describes various aspects of evidence-based medicine, systematic reviews in interventional pain management, evaluation of the strength of scientific evidence, differences between systematic and narrative reviews, rating the quality of individual articles, grading the strength of the body of evidence and appropriate methods for searching for the evidence.

This is a preliminary report of a new concept of lumbar medial branch neurotomy by measurement of minimal sensory threshold. This technique is not recommended for routine clinical use until further controlled data are available. The lumbar zygapophysial joints (Z-joint) or facet joints, are a potential source of low back pain. ⋯ The other is that the Z-joint is innervated by the sensory fibers of the medial branches. As a result, the multifidus may be successfully denervated as demonstrated by electromyography but the Z-joints may be inadequately denervated. As a result, this technique describes measurement of minimal sensory threshold prior to lesioning and seeking to double that threshold as an additional, intra-operative measure of successful sensory denervation of the Z-joint.

Clinical TrialAn intervention study to enhance postoperative pain management.
This study, conducted before and after the implementation of an acute pain service (APS) in a 1000-bed hospital, describes the process of the implementation of an APS. The nursing, anesthesia, and surgery departments were involved. In this study we sought to evaluate the results of a continuous quality improvement program by defining quality indicators and using quality tools. A quality program in accordance with current standards of acute pain treatment (multimodal) was worked out to enhance pain relief for all surgical inpatients. A survey of nurses' knowledge with regard to postoperative pain was conducted, and a visual analog scale (VAS) was introduced to assess pain intensity. Both nurses and physicians became familiar with evidence-based guidelines concerning postoperative pain. The entire process was monitored in three consecutive surveys and enrolled 2383 surgical inpatients. Pain indicators based on VAS and analgesic consumption were recorded during the first 72 postoperative hours. After a baseline survey about current practices of pain treatment, a nurse-based, anesthesiologist-supervised APS was implemented. The improvement in pain relief, expressed as VAS scores, was assessed in two further surveys. A quality manual was written and implemented. A major improvement in pain scores was observed after the APS inception (P < 0.001). ⋯ The implementation of an acute pain service, including pain assessment by a visual analog scale, standard multimodal pain treatment, and continuous quality evaluation, improved postoperative pain relief. Establishing teams of surgeons, anesthesiologists, and nurses is the prerequisite for this improvement.

The phenomenon of inflammatory masses at the tips of intrathecal drug administration catheters was the subject of a recent case-compilation report and a number of animal studies. We sought to synthesize current clinical and preclinical data to formulate hypotheses about the etiology of catheter-tip masses. ⋯ The evidence suggests that the long-term administration of opioids, especially morphine, caused the masses that were observed in humans and in two species of animals. A relationship probably exists between mass formation and intrathecal morphine doses or concentration. Other factors remain to be investigated.
