Abstract

BACKGROUND:

Chiropractic care is a common but not often investigated treatment option for back pain in Sweden. The aim of this study was to explore patient-reported outcomes (PRO) for patients with back pain seeking chiropractic care in Sweden.

METHODS:

Prospective observational study. Patients 18 years and older, with non-specific back pain of any duration, seeking care at 23 chiropractic clinics throughout Sweden were invited to answer PRO questionnaires at baseline with the main follow-up after four weeks targeting the following outcomes: Numerical Rating Scale for back pain intensity (NRS), Oswestry Disability Index for back pain disability (ODI), health-related quality of life (EQ-5D index) and a visual analogue scale for self-rated health (EQ VAS).

RESULTS:

246 back pain patients answered baseline questionnaires and 138 (56%) completed follow-up after four weeks. Statistically significant improvements over the four weeks were reported for all PRO by acute back pain patients (n = 81), mean change scores: NRS -2.98 (p < 0.001), ODI -13.58 (p < 0.001), EQ VAS 9.63 (p < 0.001), EQ-5D index 0.22 (p < 0.001); and for three out of four PRO for patients with chronic back pain (n = 57), mean change scores: NRS -0.90 (p = 0.002), ODI -2.88 (p = 0.010), EQ VAS 3.77 (p = 0.164), EQ-5D index 0.04 (p = 0.022).

CONCLUSIONS:

Patients with acute and chronic back pain reported statistically significant improvements in PRO four weeks after initiated chiropractic care. Albeit the observational study design limits causal inference, the relatively rapid improvements of PRO scores warrant further clinical investigations.
