What patient factors and Patient-Reported Outcomes Measurement Information System domains are associated with worse pain coping in pediatric orthopaedic patients in the United States?. Issue 5 (September 2021) - Bernstein, David N.
Abstract : We sought to better understand the relationship between Patient-Reported Outcomes Measurement Information System (PROMIS) mobility, pain interference (PI) and depressive symptoms scores, as well as determine what patient factors and PROMIS domains were associated with worse pain coping (PROMIS PI), in a pediatric orthopaedic population. Between 27 August 2015 and 30 April 2019, new pediatric orthopaedic patients 18 years or younger (or their guardians as a proxy) were asked to complete PROMIS mobility, PI and depressive symptoms domains at an academic medical center pediatric orthopaedic clinic. Pearson correlation coefficients ( r ) were calculated between each PROMIS domain. Linear multivariate regression analysis was used to determine patient characteristics and PROMIS domains associated with presenting PROMIS PI scores. There was a strong-moderate correlation between PROMIS mobility and PI ( r = −0.66, P < 0.001), while the correlation between PROMIS mobility and depressive symptoms was moderate-poor ( r = −0.38, P < 0.001). There was a moderate correlation between PROMIS depressive symptoms and PI ( r = 0.54, P < 0.001). In multivariate linear regression analysis, female gender (β = 0.82, P < 0.001), self-reported black race (β = 0.94, P < 0.001), Medicaid insurance (β = 0.82, P < 0.001) and worsening depressive symptoms (β = 0.33, P < 0.001) were associated with worse pain coping mechanisms, while increasing mobility (β = −0.47, P < 0.001) was associated with better pain coping mechanisms. Poor mobility and worse depressive symptoms are associated with worse pain coping mechanisms. Additionally, Medicaid insurance status, black race and female gender are also associated with worse physical limitations secondary to pain.
