Emerging strategies in health care are extremely important for interventional pain physicians, as well as with the payors in various categories. While most Americans, including the US Congress and Administration, are looking for ways to provide affordable health care, the process of transformation and emerging health care strategies are troubling for physicians in general, and interventional pain physicians in particular. With the new Congress, only new issues rather than absolute solutions seem to emerge. ⋯ The Congressional Budget Office has projected budget implications of change in the SGR mechanism, with consideration for allowing payment rates to increase by the amount of medical inflation, costing Medicare an estimated $218 billion from 2007 to 2016. Changes in the physician fee schedule in 2006 using the bottom-up methodology have resulted in significant cuts for interventional pain physicians performing procedures in an office setting. Medicaid physician payments and ambulatory surgery center payments for interventional techniques are proposed to be reduced substantially by Medicare and Medicaid, while hospital payments remain at stable levels with increases.

Review
Evidence-based interventional pain management: principles, problems, potential and applications.
The past decade has been marked by unprecedented interest in evidence-based medicine (EBM) and a focus upon the use of innovative methods and protocols to provide valid and reliable information for and about healthcare. Thus (it is at least purported that), healthcare decisions are increasingly being based upon research-derived evidence, rather than on expert opinion or clinical experience alone. But this quest for evidence to support clinical practice also compels the question of whether the methods employed to acquire information, the ranking of information that is acquired, and the prudent use of this information are sound enough to actually sustain the validity of an evidence-based paradigm in practice. Moreover, it is becoming apparent that the scope, depth, and applicability of available evidence to effectively and ethically guide the myriad of situational decisions in clinical practice is not uniform across all medical fields or disciplines. In particular, comprehensive evidence synthesis or complete guidelines for clinical decision-making in interventional pain management remain relatively scarce. EBM is defined as the conscientious, explicit, and judicious use of the current best evidence in making decisions about the care of individual patients. Thus, the practice of EBM requires the integration of individual clinical expertise with the best available external evidence from systematic research. To arrive at evidence-based medical decisions all valid and relevant evidence should be considered alongside randomized controlled trials, patient preferences, and resources. ⋯ Interpreting and understanding evidence synthesis, systematic reviews and other analytic literature is a difficult task. It is crucial for pain physicians to understand the goals, principles, and process(es) of EBM so as to meaningfully improve its application(s). This knowledge affords better insight into not only the analytic reviews in interventional pain management provided herein, but ultimately allows future information to be selected, evaluated, and used with prudence in technically competent, ethically sound medical practice.

Clinical Trial
Radiofrequency denervation of the lumbar zygapophysial joints: 10-year prospective clinical audit.
Evidence for the efficacy of zygapophysial joint nerve radiofrequency neurotomy has remained controversial. Two randomized controlled trials showed positive results, but two others demonstrated no benefit. One carefully performed prospective trial confirmed high efficacy and lasting pain relief after the procedure; however, selection criteria for this study were superfluous, which resulted in a small number of patients available for follow up. ⋯ This large, prospective clinical audit indicates that proper patient selection and anatomically correct radiofrequency denervation of the lumbar zygapophysial joints provide long-term pain relief in a routine clinical setting.

Percutaneous disc decompression utilizing Nucleoplasty has emerged as one of the minimally invasive techniques for treatment of low back pain and lower extremity pain due to contained herniated discs. Only 1 study to date has examined its effect on functional activity and pain medication use; however, results were not analyzed over time, and recall bias was a limitation. ⋯ Nucleoplasty appears to be safe and effective. Randomized, controlled studies are required to further evaluate its long-term efficacy.
