Misbeliefs about non-specific low back pain and attitudes towards treatment by primary care providers in Spain: a qualitative study

AIM: To identify misbeliefs about the origin and meaning of non-specific chronic low back pain and to examine attitudes towards treatment by primary health care providers. DESIGN: Generic qualitative study. METHODS: Ten semi-structured interviews were conducted between October and November 2016 with physicians and nurses from primary health care centres in Lleida. The interviews were transcribed and analysed using inductive thematic analysis via Atlas.ti-8 software. RESULTS: Five themes were identified: i. beliefs about the origin and meaning of chronic low back pain, ii. psychosocial aspects of pain modulators, iii. Therapeutic exercise as a treatment for chronic low back pain, iv. biomedical attitudes of primary health care providers, and v. difficulties in the clinical approach to chronic low back pain. CONCLUSION: Primary health care providers have a unifactorial view of chronic low back pain and base their approach on the biomedical model. Professionals attribute chronic low back pain to structural alterations in the lumbar spine while psychosocial factors are only recognized as pain modulators. For professionals, therapeutic exercise represents a possible solution to chronic low back pain; however, they still do not prescribe it and continue to educate on postural hygiene and recommend limiting physical and/or occupational activities, as opposed to clinical practice guidelines. These findings suggest that to improve the adherence of primary health care providers to the biopsychosocial model, it may be necessary first to modify their misbeliefs about non-specific chronic low back pain by increasing their knowledge on pain neurophysiology.
