BackTrAC: A Digital Care Pathway for People Presenting to Emergency with Lower Back Pain. A Development and Feasibility Study Protocol.

Objectives: Back pain is a prevalent condition that affects 1 in 6 Australians at any time, with high associated health care costs. To date, there is limited information relating to symptom severity and recovery trajectory in people with back pain who present to the emergency department for care. A digital care pathway (DCP) can track patient outcomes following presentation with back pain. The primary aim of this protocol is to outline the co-development, implementation, and evaluation of a DCP for back pain patients who present to the emergency department.

Methods: The primary aim will be addressed in 3 overlapping phases: Phase 1 (co-design) will include interviews with back pain patients and health care professionals from the Northern Hospital Emergency Department. Interview findings will inform education resources featured on the DCP and establish questionnaire content and frequency acceptability. Phase 2 (implementation) will include the rollout of the DCP and tracking of patient-reported outcome measures, which will be collected over 12 weeks. Phase 3 (evaluation) will include interviews with a subset of back pain patients who have participated in Phase 2 to evaluate the acceptability of the DCP and the barriers and facilitators of using the DCP.

Ethics and dissemination: This project has been approved via the National Health and Medical Research Council of Australia's National Mutual Acceptance Scheme by St Vincent's Hospital Human Ethics Committee (2022/PID06476), La Trobe University Research Governance (HEC#206/22), and Northern Health Research Governance (NH-2023-372687). We plan to publish the findings in a peer-reviewed journal and present them at conferences.
