The Danish Chiropractic low back pain Cohort (ChiCo)

Short summary

The ChiCo cohort includes comprehensive patient reported and clinician reported information on adults seeking care for back pain and standardised coding of images from a subsample examined with radiographs or MRI scans. Frequent follow-ups are conducted during 1 year after inclusion. Based on the data from the cohort we will investigate the value and effects of imaging in primary care back pain patients, the importance of health beliefs, reasons for care seeking, the validity of existing predictive models and the potential for early identification of people at risk for long-term sick leave. 


Rationale

One in six Danes suffers from back pain, 20% of all sick days in Denmark are due to LBP, and it is the most frequent reason for care seeking. National clinical guidelines support non-pharmalogical interventions such as manual therapy and supervised exercises. However, we have surprisingly little insight into who seeks this type of care, how other co-morbidities influence prognosis and treatment effects, and how important aspects of the clinical consultation such as preconceived ideas about the condition (including beliefs about imaging and treatments) affect the clinical course. Moreover, we know little about the extent to which guidelines on imaging are implemented and to which extent imaging informs and affects care for back pain.

RCTs are not well suited to answering these important clinical questions and it has been proposed that large scale cohorts in spine pain should be a research priority.

The ChiCo cohort will register data from a large group of LBP patients (n=5000) from Danish chiropractic clinics that will create the basis for answering a range of research questions. The main research focus will be on LBP but questions related to other musculoskeletal complaints in people with LBP can also be addressed.

Pre-planned research projects include investigating:

  • The profile of chiropractic patients, their clinical course and prognosis
  • The prognostic value of radiographic findings in patients with low back pain
  • Illness belief, expectations and clinical decision making in chiropractic practice
  • The validity of existing low back pain prediction models
  • The validity of previously identified back pain trajectories


Description of the cohort

Patients above 18 years of age consulting chiropractors with a primary complaint of low back pain.

Patients should consult with a new episode of back pain (defined as not having initiated a course of chiropractic care prior to inclusion).

To be included patients need to understand and read Danish and have access to e-mail and SMS.

Participants are recruited from private chiropractic practices in the Central Denmark Region. 


Data and biological material

Patient reported questionnaires include information about sociodemographic factors, pain, activity limitation, work, psychological factors and general health.

Participants are surveyed at the time of the first consultation and after 2 weeks, 3 months and 12 months. In addition they are followed by SMS at 34 time points during 12 months.

Clinician reported items, at the first visit, include clinical examination findings, red flags and indications for imaging registered.

Findings on imaging in the subgroup of patients who have imaging are systematically coded.
