In this update, I will summarize key points from recent scientific literature regarding the practice of chiropractic, patient profiles, utilization rates, chiropractic assessment and care methods.  Much of the information comes from the excellent work of Beliveau et al (2017) who did a scoping review and used 337 articles from across the globe. I have provided references to other key papers also.

Chiropractors practice in over 100 countries.  There are 90 existing national chiropractic associations across the world. Chiropractic has become one of the most commonly used health professions in the United States and Europe. A substantial proportion of US adults utilize chiropractic services and report associated positive outcomes for overall well-being and/or specific health problems for which concurrent conventional care was common (1). Chiropractors provide a significant amount of care for patients with many health conditions including low back and neck pain. The profession is a major participant in the health care expenditures of the United States and Denmark. As an example, here in the United States in 2015, chiropractors provided 18.6 million clinical services under Medicare and overall spending for chiropractic services was estimated at USD $12.5 billion (Beliveau et al, 2017).

According to the American Chiropractic Association (2), there are 77,000 chiropractors in the United States with roughly another 3,000 chiropractors that work in academic and management roles. There are approximately 10,000 chiropractic students in 18 nationally accredited, chiropractic doctoral programs across the United States with 2,500 chiropractors entering the work environment each year. Estimates indicate that chiropractors treat more than 35 million Americans (adults and children) annually. Chiropractors are designated as physician-level providers in the vast majority of states and the federal Medicare program. The essential services provided by chiropractors are also available in federal health delivery systems, including those administered by Medicaid, the U.S. Departments of Veterans Affairs (VA) and Defense, Federal Employees Health Benefits Program, Federal Workers’ Compensation, and all state workers’ compensation programs. Chiropractic is currently offered at 75 VA facilities and 66 military hospitals/clinics.

National and international guidelines include chiropractic (spinal manipulation) for low back pain (LBP) and neck pain. A short summary (3-4) of recent guidelines include:

• For acute and chronic LBP, a review of clinical practice guidelines (CPGs) on the noninvasive management of LBP and 3 national CPGs published since 2016 in the United States (Agency for Healthcare Research and Quality [AHRQ] comparative effectiveness review [CER]), the UK (National Institute for Care Excellence [NICE]), and Denmark (Denmark National Guideline) recommend considering manual therapy, including SMT, mobilization, or soft tissue techniques such as massage
• An additional CPG, by the American College of Physicians (ACP), recommends clinicians select nonpharmacologic treatment for acute and chronic LBP (superficial heat, massage, acupuncture, and SMT) before pharmacologic treatment options

Chiropractic utilization rates

• Across the world, 52 studies (Beliveau et al, 2017) have found the median 12-month use of chiropractic services was 9.1% and lifetime utilization was 22.2%
• In Canada and the United States there has been an increased 12 month utilization rate from 10% to 11.7% and from 7.2% to 10.7% respectively from the 1980’s until 2015

Who delivers spinal manipulation?

• Among the 8.5% of US adults who reported receiving manipulation, 97.6% saw chiropractors according to the 2012 National Health Interview Survey (5)

Reasons for seeing a chiropractor

• For the general population, the most common reasons for seeking care from a chiropractor included: low back pain (49.7%), neck pain (22.5%), extremity problem (10%), wellness/maintenance (7.5%), hip pain (7%), headache (5.5%)
• For the pediatric population, the most common reasons for seeking care from a chiropractor included: musculoskeletal conditions (44%), excessive crying (19.8%), neurologic conditions (17.9%), gastrointestinal conditions (17.5%), ear/nose/throat conditions (8.3%) and infection (7%) (Beliveau et al, 2017)

Profile of chiropractic patients

• People who sought chiropractic care were more likely to be female with a median age of 43.4 years
• 3% of the chiropractic patient population were employed, and a smaller proportion were either retired, unemployed, or students
• People with disabilities constituted only 1.4% of chiropractic patients (Beliveau et al, 2017)

Types of chiropractic assessments used in practice

• The most common assessment methods included: static palpation (89.3%), motion palpation (86.5%), spinal examination (79.5%), orthopedic examination (71.8%), neurological examination (64.6%) (Beliveau et al, 2017)

Types of chiropractic treatment provided

• Across the globe, spinal manipulation (79.3%), soft-tissue therapy (35.1%), formal patient education (31.3%), nutritional supplements (30.9%), exercise instruction/prescription (26%)
• Interestingly the NBCE (National Board of Chiropractic Examiners) found that in the US: 98.8% of chiropractors provide ergonomic/postural advice, 98.5% of chiropractors provide physical fitness/exercise promotion and 97% of chiropractors provide nutritional/dietary recommendations (Beliveau et al, 2017)
