Design outcomes

Primary

MeasureTime frame
Time until ‘full’ sustained return to any work, defined as work resumption to the same hours as prior to joint replacement, in any role, without any day of sick leave for a consecutive 4-week period. This is measured monthly via questionnaire.

Secondary

MeasureTime frame
1. Time to any return to work, measured monthly via questionnaire. 2. Measures of functional recovery to daily activities and social participation using the following: 2.1. Oxford hip/knee score (OKS/OHS) - at baseline, 3, 6, 9, and 12 months. 2.2. Lower extremity functional scale (LEFS) - at baseline, 3, 6, 9, and 12 months. 2.3. PROMIS social participation short form questionnaires (social roles and activities questionnaire, satisfaction with participation in social roles questionnaires) - at baseline, 3, 6, 9, and 12 months. 3. Number of ‘sick days’ between surgery and ‘full’ sustained return to work - measured monthly via questionnaire. 4. Participant adherence to the intervention and the intervention’s physical rehabilitation programme - self-reported Likert scales upon achieving the primary outcome. 5. Proportion of participants using workplace interventions, adaptions and modifications to facilitate their RTW measured by questionnaire upon achieving the primary outcome. 6. Health-related quality of life measured via EQ-5D-5L at baseline, 3, 6, 9, and 12 months. 7. Work Productivity measured via Work Limitations Questionnaire at baseline, 3, 6, 9, and 12 months.
