Most studies that look at long-term effects of treatment simply look at self-reported outcomes: level of pain and disability. This study took a different approach. By examining how much care patients sought after the initial study period, they could determine the effect each treatment method had on future health care consumption:
“Care seeking behavior by patients with low back pain is most commonly associated with increased pain and disability, meaning more care is sought when worse symptoms are experienced. The amount of health care utilized may therefore be used as a measure of patient health status, and thus may be compared between groups of patients to determine effectiveness of certain therapies.”
The authors started with 191 patients with low back pain. 107 patients received chiropractic care and 84 patients received active exercise therapy from physical therapists. All patients received treatment 2 to 4 times per week for four weeks. The study subjects were then followed for one year to assess outcomes. The authors found:
38% of the chiropractic care patients and 54% of the physical therapy patients sought care for their back pain during the one-year follow-up. Chiropractic patients had an average of 2.2 visits to a health care provider after the treatment period, while physical therapy patients had an average of 6 visits.
“We hypothesized that there would be no group difference in the average number of visits to any health care provider. The results demonstrated that actually there were significant group differences during the year after trial participation, with a higher number of visits to any health care provider and to a general practitioner in the EP group.”
The authors conclude:
“Based on one-year follow-up data imputed for complete analysis, participants who received physical therapy (exercise program) during a clinical trial attended a higher number of visits to any health care provider and to general practitioners during the year after care when compared to participants who received chiropractic care (flexion distraction) within the trial.”
