Health Care Costs for Back Pain Much Higher when Care Initiated with an MD vs DC
A new study finds that low back pain care initiated with a doctor of chiropractic (DC) saves 40 percent on health care costs when compared with care initiated through a medical doctor (MD), the American Chiropractic Association (ACA) announced today. The study, featuring data from 85,000 Blue Cross Blue Shield beneficiaries, concludes that insurance companies that restrict access to chiropractic care for low back pain treatment may inadvertently pay more for care than they would if they removed such restrictions.
Low back pain is a significant public health problem. Up to 85 percent of Americans have back pain at some point in their lives. In addition to its negative effects on employee productivity, back pain treatment accounts for about $50 billion annually in health care costs—making it one of the top 10 most costly conditions treated in the United States.
The study, “Cost of Care for Common Back Pain Conditions Initiated With Chiropractic Doctor vs. Medical Doctor/Doctor of Osteopathy as First Physician: Experience of One Tennessee-Based General Health Insurer,” which is available online and will also be published in the December 2010 issue of the Journal of Manipulative and Physiological Therapeutics, looked at Blue Cross Blue Shield of Tennessee’s intermediate and large group fully insured population over a two-year span. The insured study population had open access to MDs and DCs through self-referral, and there were no limits applied to the number of MD/DC visits allowed and no differences in co-pays.
Results show that paid costs for episodes of care initiated by a DC were almost 40 percent less than care initiated through an MD. After risk-adjusting each patient’s costs, researchers still found significant savings in the chiropractic group. They estimated that allowing DC-initiated episodes of care would have led to an annual cost savings of $2.3 million for BCBS of Tennessee.
“As doctors of chiropractic, we know firsthand that our care often helps patients avoid or reduce more costly interventions such as drugs and surgery. This study supports what we see in our practices every day,” said ACA President Rick McMichael, DC. “It also demonstrates the value of chiropractic care at a critical time, when our nation is attempting to reform its health care system and contain runaway costs.”
The American Chiropractic Association, based in Arlington, Va., is the largest professional association in the United States representing doctors of chiropractic. ACA promotes the highest standards of ethics and patient care, contributing to the health and well-being of millions of chiropractic patients.
ABSTRACT
Cost of care for common back pain conditions initiated with chiropractic doctor vs medical doctor/doctor of osteopathy as first physician: experience of one Tennessee-based general health insurer.
OBJECTIVE: The primary aim of this study was to determine if there are differences in the cost of low back pain care when a patient is able to choose a course of treatment with a medical doctor (MD) versus a doctor of chiropractic (DC), given that his/her insurance provides equal access to both provider types.
METHODS: A retrospective claims analysis was performed on Blue Cross Blue Shield of Tennessee's intermediate and large group fully insured population between October 1, 2004 and September 30, 2006. The insured study population had open access to MDs and DCs through self-referral without any limit to the number of visits or differences in co-pays to these 2 provider types. Our analysis was based on episodes of care for low back pain. An episode was defined as all reimbursed care delivered between the first and the last encounter with a health care provider for low back pain. A 60 day window without an encounter was treated as a new episode. We compared paid claims and risk adjusted costs between episodes of care initiated with an MD with those initiated with a DC.
RESULTS: Paid costs for episodes of care initiated with a DC were almost 40% less than episodes initiated with an MD. Even after risk adjusting each patient's costs, we found that episodes of care initiated with a DC were 20% less expensive than episodes initiated with an MD.
CONCLUSIONS: Beneficiaries in our sampling frame had lower overall episode costs for treatment of low back pain if they initiated care with a DC, when compared to those who initiated care with an MD.
