Low back pain affects many individuals. It has profound effects on well-being and is often the cause of significant physical and psychological health impairments. Low back pain also affects work performance and social responsibilities, such as family life, and is increasingly a major factor in escalating health-care costs. A global review of the prevalence of low back pain in the adult general population has shown its point prevalence to be approximately 12%, with a one-month prevalence of 23%, a one-year prevalence of 38%, and a lifetime prevalence of approximately 40%. Furthermore, as the population ages over the coming decades, the number of individuals with low back pain is likely to increase substantially. This comprehensive review is undertaken to assess the increasing prevalence of low back pain and the influence of comorbid factors, along with escalating costs. ⋯ Although it has been alleged that low back pain resolves in approximately 80% to 90% of patients in about six weeks, irrespective of the administration or type of treatment, with only 5% to 10% of patients developing persistent back pain, this concept has been frequently questioned as the condition tends to relapse and most patients experience multiple episodes years after the initial attack.

Spinal cord stimulation (SCS) is well accepted for the treatment of chronic pain since its beginning in 1967. As its use continues to enter into the chronic pain treatment algorithm earlier, conscience patient selection and durability of the therapy are clearly clinically relevant. To improve treatment efficacy, consensus statements and guidelines were developed. ⋯ The current available guideline statements have clear deficiencies in either scope of coverage, evidence synthesis, or lack of transparency of funding. Improved evidence and best practice/guideline assessment may improve patient outcomes and accessibility to these important modalities. Further prospective comparator randomized data are required to not only provide data of clinical and cost-effectiveness in other indications but also to better describe the position of neurostimulation application within the disease management pathway. Therein cases where there appears to be sufficient evidence and consensus, every effort should be made to secure access to these effective therapies. Importantly, each guideline only has a useful clinical half-life, if not updated. This should be acknowledged by both clinicians and third-party payers. Based on these deficiencies, the International Neuromodulation Society recommended the creation of a consensus conference to examine the appropriate use of neurostimulation for pain and ischemic disease.

Low back pain (LBP) is a highly prevalent condition and one of the leading causes of lost productivity and health-care costs. The objective of this review is to discuss the role of interventional pain procedures and evidence of their effectiveness in treatment of chronic LBP. ⋯ Implementation of interventional pain procedures in the treatment framework of LBP has resulted in improvement of pain intensity in at least the short and medium terms, but equivocal results have been observed in functional improvement.

Review
A review of economic factors related to the delivery of health care for chronic low back pain.
We describe tools used to evaluate the economic impact of health care interventions, discuss the economic burden of chronic low back pain, and review evidence on the cost-effectiveness of treating failed back surgery syndrome with spinal cord stimulation, intrathecal drug delivery, acupuncture, epidural injections, disc prosthesis, lumbar fusion, and noninvasive therapies. We also mention the lack of cost studies for emerging therapies, such as vibrotherapy and peripheral nerve field stimulation. Topics include types of cost studies; the economic perspectives taken by such studies; direct and indirect costs; measures of success; definitions of cost-effectiveness, incremental cost-effectiveness, incremental cost-utility ratios, and quality-adjusted life years; the concept of maximum willingness to pay; and the use of cost-effectiveness models. ⋯ The fact that chronic low back pain arises from a variety of causes makes choosing appropriate treatment difficult. Determining the cost-effectiveness of various treatments for chronic low back pain depends on well-designed and well-executed randomized controlled trials with parallel economic evaluations. Researchers can use economic models to extrapolate costs and outcomes over the long term.

The issue of low back pain (LBP) is as common as it is perplexing. LBP is thought to be a chronic issue in approximately 10% of the U.S. population. This condition has wide-reaching social and economical reverberations. Despite the availability of modern diagnostic tools, the cause of the pain generator is often unidentifiable. The authors were asked to create an overview of the etiology of LBP for physicians who implant neurostimulation devices for the treatment of chronic pain patients. Some prevalence data, based on the current available literature, have been provided for the more common structural conditions causing LBP. However, a comprehensive review of prevalence of various conditions and their respective manifestations as LBP is beyond the scope of this article. ⋯ LBP is an extremely common condition associated, as a symptom, with various disease processes, regardless of their relationship with the lumbar spine or its innervation. This article underscores the broad nature of LBP as a symptom of many diagnoses. The primary conclusion reached by the authors is the most important recommendation by all mentors in medicine, which is to obtain a comprehensive history and perform a complete physical examination on each patient. Despite the fact that there is an emerging school of thought questioning the validity of the physical examination, this tool continues to be the current standard of care and used by a majority of clinicians around the world. The physician must analyze the information obtained from his/her history, physical examination, and diagnostic tools with the recognition of the broad nature of the differential diagnoses of LBP in order to be able to best treat the patient.
