Comparing satisfaction with a participatory driven web-application and a standard website for patients with low back pain: a study protocol for a randomised controlled trial (part of the ADVIN Back Trial).

Background: Low back pain (LBP) is the most common musculoskeletal disorder and a leading cause of disability worldwide. It impacts daily life and work capacity and is the most common reason for consulting a general practitioner (GP). According to international guidelines, information, reassurance, and advice are key components in the management of people with LBP; however, the consultation time available in general practice for each patient is often limited. Therefore, new methods to support the delivery of information and advice are needed and online technologies provide new opportunities to extend the consultation beyond the GP's office. However, it is not known whether GPs and people consulting their GP because of LBP will accept online technologies as part of the consultation. By involving patients in the development of online information, we may produce more user-friendly content and design, and improve patient acceptance and usage, optimising satisfaction and clinical outcomes. The purpose is to study satisfaction in people consulting their GP with LBP depending on whether they are randomised to receive supporting information through a new participant-driven web application or a standard reference website containing guideline-based information on LBP. It is hypothesised that patients offered information in a new web application will be more satisfied with the online information after 12 weeks compared to patients allocated to a standard website.

Methods: Two hundred patients with LBP aged ≥ 18 years consulting Danish general practice will be randomly allocated 1:1 to either the new web application or standard online information in permuted blocks of two, four, and six. Patients with serious spinal diseases (cancer, fractures, spinal stenosis, spondyloarthritis), those without Danish reading skills or without online access, and pregnant women will not be included in the trial. Patient satisfaction measured by the Net Promotor Score after 12 weeks is the primary outcome. Patients will be aware of their allocation. GPs will be blinded unless informed by the patient. Assessors are blinded.

Discussion: To our knowledge, this is the first trial evaluating whether involving LBP patients in the development of an online web application will result in higher patient satisfaction.
