Assessment of functioning and disability in patients with low back pain - the low back pain assessment tool. Part 2: field-testing

PURPOSE: To evaluate comprehensiveness and acceptability of the patient-reported outcome instrument (PRO-LBP) and the clinician-reported outcome instrument (ClinRO-LBP) included in the low back pain (LBP) assessment tool. Second, to assess degree of implementation after three months.

METHODS: Feasibility-testing, training of health professionals, field-testing, and a feedback meeting was undertaken. Field-testing provided data to evaluate comprehensiveness, acceptability, and degree of implementation.

RESULTS: Feasibility-testing and training of health professionals revealed that the LBP assessment tool was usable and ready for field-testing. In total, 152 patients participated in the field-testing of whom 95% considered the PRO-LBP comprehensive and 59% found it acceptable. Health professionals found the ClinRO-LBP comprehensive and acceptable. The feedback meeting revealed that the LBP assessment tool broadened the health professionals' approach to functioning and facilitated a consultation based on the patient perspective. The degree of implementation reached 79%.

CONCLUSIONS: The PRO-LBP and the ClinRO-LBP covered key concepts of LBP and were found acceptable by patients and health professionals. Despite the reduced degree of implementation after three months the LBP assessment tool allowed the health professionals to apply a biopsychosocial and patient-centred approach. Future research should investigate whether the LBP assessment can enhance patient-centred care.Implications for rehabilitationThe low back pain (LBP) assessment tool is the first evidence-based tangible tool to cover biopsychosocial aspects related to LBP as defined by the International Classification of Functioning, Disability and Health (ICF).The LBP assessment tool allowed health professionals to apply a biopsychosocial and patients-centred approach and has the potential to be used in rehabilitation planning.Awareness to continuous facilitation and training of health professionals is important to facilitate and maintain implementation of new procedures into routine clinical practice.
