Background: Many clinical practice guidelines for management of pain disorders now favor first-line use of nonpharmacological therapies (NPT). However, Medicare coverage of NPT is limited. Methods: Using a serial cross-sectional design, we examined temporal trends in the utilization and cost of NPT procedures commonly used to treat pain under Medic...
Background
The cost of spine-related pain in the United States is estimated at $134.5 billion. Spinal pain patients have multiple options when choosing healthcare providers, resulting in variable costs. Escalation of costs occurs when downstream costs are added to episode costs of care. The purpose of this review was to compare costs of chiropracti...

Background
Primary Spine Care (PSC) is an innovative model for the primary management of patients with spine-related disorders (SRDs), with a focus on the use of non-pharmacological therapies which now constitute the recommended first-line approach to back pain. PSC clinicians serve as the initial or early point of contact for spine patients and ut...
Background
The burden of spinal pain can be aggravated by the hazards of opioid analgesics, which are still widely prescribed for spinal pain despite evidence-based clinical guidelines that identify non-pharmacological therapies as the preferred first-line approach. Previous studies have found that chiropractic care is associated with decreased use...

The objective of this investigation was to evaluate the association between utilization of chiropractic services and the use of prescription opioid medica...
Introduction:
Insurance reimbursement for clinical services provided by complementary healthcare professionals in the United States likely differs by provider specialty. It is hypothesized that a lower likelihood of insurance reimbursement demonstrates that complementary healthcare services are not utilized to an optimal level and are not financia...
With the advent of new models for payment and delivery of healthcare services, the use of quality measures for continual improvement of clinical healthcare is now an integral feature of medical practice in the United States. However, quality measurement and quality improvement activities are not common practice among integrative health providers. T...

Medicare covers chiropractic care, but the health-care community knows little about the demographic characteristics of older adults who use chiropractic services under the Medicare program. Researchers do not know the demographic composition of chiropractic users under Medicare, how the demographics of chiropractic use and rates of use have changed...
In 2005-2007, The Centers for Medicare and Medicaid Services conducted the Demonstration of Expanded Coverage of Chiropractic Services under Medicare in selected counties in five states. The official evaluation showed that the project was essentially budget-neutral in four states. In Illinois however, Medicare expenditures were approximately $50M h...

We designed an investigation intended to determine the incidence of registry records with noncodable trauma diagnoses, characterize those records, and determine the reasons for inadequate diagno...
We hypothesize that stasis of the cerebrospinal fluid (CSF) occurs commonly and is detrimental to health. Physiologic factors affecting the normal circulation of CSF include cardiovascular, respiratory, and vasomotor influences. The CSF maintains the electrolytic environment of the central nervous system (CNS), influences systemic acid-base balance...
Spinal manipulation is a safe and effective therapy for spinal pain disorders of mechanical origin, and has been identified as a treatment of choice for certain conditions. Chiropractic is the health profession that most commonly delivers spinal manipulation. Chiropractors are highly educated and receive thorough training in spinal manipulation. Ma...
