Review Comparative Study
The impact of comparative effectiveness research on interventional pain management: evolution from Medicare Modernization Act to Patient Protection and Affordable Care Act and the Patient-Centered Outcomes Research Institute.
The Patient-Centered Outcomes Research Institute (PCORI) was established by the Affordable Care Act of 2010 to promote comparative effectiveness research (CER) to assist patients, clinicians, purchasers, and policy-makers in making informed health decisions by advancing the quality and relevance of evidence concerning the manner in which diseases, disorders, and other health conditions can effectively and appropriately be prevented, diagnosed, treated, monitored, and managed through research and evidence synthesis. The development of PCORI is vested in the Medicare Modernization Act (MMA) and the American Recovery and Reinvestment Act (ARRA). The framework of CER and PCORI describes multiple elements which are vested in all 3 regulations including stakeholder involvement, public participation, and open transparent decision-making process. ⋯ Further, stakeholders in PCORI are not scientists, are not balanced, and will set an agenda with an ultimate problem of comparative effectiveness and PCORI that it is not based on medical science, but rather on political science and not even under congressional authority, leading to unprecedented negative changes to health care. Thus, PCORI is operating in an ad hoc manner that is incompatible with the principles of evidence-based practice. This manuscript describes the framework of PCORI, and the role of CER and its impact on interventional pain management.

Intrathecal drug infusion therapy is usually considered when spinal-acting analgesics or antispasmodics administered via the oral or transdermal routes fail to control patients' pain or are associated with unacceptable side effects. The intrathecal administration of centrally acting agents bypasses the blood-brain-barrier resulting in much higher cerebrospinal fluid (CSF) concentrations while using reduced amounts of medication to achieve equipotent doses. The intrathecal approach is associated with higher rates of satisfactory pain relief and lower rates of treatment failures and technical complications compared to the epidural route. A paucity of randomized controlled trials (RCTs) has led to concern regarding proper use, selection criteria, and safety of these devices. Cost effectiveness and comparative therapies have now also become a focus of discussion. ⋯ Based on the available evidence, the recommendation for intrathecal infusion systems for cancer-related pain is moderate recommendation based on the high quality of evidence and the recommendation is limited to moderate based on the moderate quality of evidence from non-randomized studies for non-cancer related pain.
