Available evidence documents a wide degree of variance in the definition and practice of interventional pain management. ⋯ The indicated evidence for therapeutic interventions is variable from Level I to III. This comprehensive review includes the evaluation of evidence for therapeutic procedures in managing chronic spinal pain and recommendations. However, this review and recommendations do not constitute inflexible treatment recommendations or "standard of care."

Documentation assists health care professionals in providing appropriate services to patients by documenting indications and medical necessity, and reflects the competency and character of the physician. Documentation is considered a cornerstone of the quality of patient care. This is nowhere more true than in interventional pain management. ⋯ Evaluation and management services incorporate 5 levels of service for consultations and visits, with multiple key elements of service including history, physical examination, and medical decision making. Documentation of interventional procedures in general requires a history and physical, indication and medical necessity, intra-operative procedural description, post-operative monitoring and ambulation, discharge, and disposition. With minor variations, these requirements are similar for an in-office setting, hospital out patient department, and ambulatory surgery centers.

Understanding the neurophysiological basis of chronic spinal pain and diagnostic interventional techniques is crucial in the proper diagnosis and management of chronic spinal pain. Central to the understanding of the structural basis of chronic spinal pain is the provision of physical diagnosis and validation of patient symptomatology. It has been shown that history, physical examination, imaging, and nerve conduction studies in non-radicular or discogenic pain are unable to diagnose the precise cause in 85% of the patients. In contrast, controlled diagnostic blocks have been shown to determine the cause of pain in as many as 85% of the patients. ⋯ These guidelines include the evaluation of evidence for diagnostic interventional procedures in managing chronic spinal pain and recommendations. However, these guidelines do not constitute inflexible treatment recommendations. These guidelines also do not represent a "standard of care."

Persistent pain interfering with daily activities is common. Chronic pain has been defined in many ways. Chronic pain syndrome is a separate entity from chronic pain. ⋯ The additional costs of misuse, abuse, and addiction are enormous. Comorbidities including psychological and physical conditions and numerous other risk factors are common in spinal pain and add significant complexities to the interventionalist's clinical task. This section of the American Society of Interventional Pain Physicians (ASIPP)/Evidence-Based Medicine (EBM) guidelines evaluates the epidemiology, scope, and impact of spinal pain and its relevance to health care interventions.

Calcineurin may be involved in affecting nociceptive processes in multiple circumstances. It is conceivable that interfering with calcineurin's normal role in contributing to glial resting membrane potential, via its effects on the ion channel (TRESK) [tandem-pore-domain weakly inward rectifying potassium channels (TWIK)-related spinal cord potassium channels] may facilitate nociception. Another aspect of calcineurin function may be its role in the pronociceptive signaling of nuclear factor of activated T-cells (NFAT). ⋯ In fact, multiple articles have described the clinical use of calcineurin-inhibitors leading to pain, a phenomenon referred to as calcineurin inhibitor-induced pain syndrome (CIPS). Thus, it appears that calcineurin functions may encompass actions which promote or dampen nociceptive processes. A greater understanding of the physiology of calcineurin, especially as it relates to modulating nociception may lead to the development of novel analgesic targets in attempts to optimally alleviate patient discomfort.
