Caregiver Patient Reported Outcomes Measurement Information System (PROMIS) profiles in patients undergoing total joint arthroplasty and spine surgery: a prospective observational cohort study

Background/ObjectiveThe role of caregiver psychosocial characteristics and their relation to postsurgical caregiving capability remains unclear. The objective of this study was to explore caregiver psychosocial variables following surgery of patients undergoing total joint arthroplasty and spine surgery.MethodsA prospective observational study was conducted where questionnaires were administered to caregivers preoperatively and 1 week/2 weeks/1 month postoperatively. Measures included demographics, caregiver activities and National Institutes of Health Patient Reported Outcomes Measurement Information System (NIH PROMIS) item banks. Bivariate analysis assessed differences between participants reporting baseline pain and those reporting no baseline pain. Generalized estimating equation models examined PROMIS T-scores across time.Results190 caregivers were enrolled and completed surveys. 18% of caregivers reported experiencing a painful condition where they experienced pain during most days of the week. Across all time points, the majority of caregivers reported no worse than mild impairment across PROMIS scores. Compared with baseline, caregivers reported lower PROMIS satisfaction with social roles across all postoperative time points (pConclusionWhile there were transient worsening in PROMIS scores, it is unclear whether these were clinically meaningful. Postsurgical caregivers reporting baseline pain were characterized by worse functioning across all PROMIS scales.
