Title: Development of a patient-reported outcome instrument for patients with lumbar radicular pain - STUDY PROTOCOL

Objective: To develop and pilot test a patient-reported outcome (PRO) instrument based on the International Classification of Functioning, Disability and Health (ICF) to assess functioning in patients with lumbar radicular pain.

Methods: The PRO will be developed with direct input from patients with lumbar radicular pain (n=10) and clinicians with extensive experience assessing and treating the population (n=10). The development of the PRO will be based on ICF Comprehensive Core Set for Low Back Pain and Rehabilitation Set. The development process will be divided into three steps. First, patients and clinicians select meaningful categories from the two ICF sets. A three round web based consensus process will be used, and specified criteria for consensus will determine which ICF categories should be included in the PRO. Secondly, items from the PROMIS® Physical Functioning item bank will be linked to ICF, and items corresponding to the included categories will be identified. Thirdly, patients and clinicians will select suitable PROMIS® items to be included in the PRO by means of another web based consensus process. The PRO will then be pilot tested (Alfa test) among the participating patients and clinicians. Adjustments will be done due to results from the Alfa test, and a Beta test among patients in the target population will be performed (n=100). In both Alfa and Beta test the patients have to respond additional questions to test face validity, construct- and content validity.
The development process starts in august 2016, with completion December 2017.

Results: The development process and preliminary results will be presented at the conference.

Conclusions: The study develops a PRO, based on ICF and PROMIS® Physical Functioning item bank, to be used in clinical practise in order to systemize and qualify the description of functioning among patients with lumbar radicular pain.
