Brief Summary

An international Consortium (BACk pain in Elders: BACE) was established in 2008 in order to create standardised methodology for large cohort studies and share data on the burden of back pain in older people. BACE cohort studies have been established in several countries with the primary objective to establish the clinical course and burden of back pain in elderly, to identify prognostic factors for chronic back pain and disability, and to explore usual care provided in primary care. The BACE-N is a BACE cohort study conducted in Norway, including a broad network of clinicians covering general practitioners, physiotherapists and chiropractors working in the primary healthcare. The BACE-N project will provide new knowledge on prognosis of back-related disability and pain in elderly people who seek help in the primary healthcare, the clinical course of back pain over two follow-up years, including a thorough description of healthcare utilisation and their costs, and prognostic factors that influence good or poor prognosis for these people.

Outcome Measures

Primary Outcomes (4)

  • the Roland Morris Disability Questionnaire

    Scores range from 0 to 24. Higher scores indicate more severe pain and disability.

    12 months follow-up

  • the Roland Morris Disability Questionnaire

    Scores range from 0 to 24. Higher scores indicate more severe pain and disability.

    24 months follow-up

  • Numerical Pain Rating Scale

    pain severity for back and leg pain assessed on a score from 0 (no pain) to 10 (maximum pain). Back and leg pain is scored separately.

    12 months follow-up

  • Numerical Pain Rating Scale

    pain severity for back and leg pain assessed on a score from 0 (no pain) to 10 (maximum pain). Back and leg pain is scored separately.

Study Arms (1)

Elderly with back pain in primary healthcare

Consecutive women and men 55 years of age or older who seek primary care (GP, physiotherapist or chiropractor) with a new episode of back pain (preceded by 6 months without visiting a primary care provider for similar complaints)

Other: Usual care

Interventions

Since this is an observational study there will be no interference with the care given by the primary healthcare providers. However, the usual care provided by these and other healthcare utilization used by the patients during follow-up will be recorded during the follow-ups.

Eligibility Criteria

Age55 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Patients are recruited from a range of general practitioners (GPs), physiotherapists (PTs), and chiropractors working in the primary care in Norway. Patients who fit the eligibility criteria and complete the consent to participate respond to a comprehensive baseline questionnaire and undergo a standardised physical examination. The questionnaire is preferably completed electronically, but a paper version is also available for patients who are not familiar with an electronic data collection.

You may qualify if:

  • seek primary care (GP, physiotherapist or chiropractor)
  • new episode of back pain
  • no visit of primary care the preceding 6 months for back pain

You may not qualify if:

  • cognitive impairments
  • difficulties speaking and writing Norwegian
  • severe mobility impairments (can not attend physical examination)
