Beyond the Chest Wall: Examining the Relationship between Morphological Features and Psychosocial Distress in Pectus Excavatum Patients

Abstract

Introduction Pectus excavatum patients frequently experience psychosocial distress, yet the relationship with morphological features of the deformity remains unexplored. We hypothesize that certain morphological features analyzed by 3D optical surface imaging contribute more prominently to the distress experienced by pectus excavatum patients as they impact the visible severity of the deformity.

Materials and Methods Consecutive pectus excavatum patients who received three-dimensional optical surface imaging between August 2019 and November 2022 were included. Logistic regression analysis assessed the association between morphological features and psychosocial distress in which the distress was scored as a binary variable, based on a self-reported assessment.

Results Among 215 patients, 55% reported psychosocial distress with multivariable analyses revealing greater depth and length of the deformity being significantly correlated with psychosocial distress. However, this prediction model demonstrated a moderate discriminative ability with an area under the receiver operating characteristic curve of 0.66 (95% confidence interval [CI], 0.59–0.73) for pectus depth and 0.58 (95% CI, 0.51–0.66) for pectus length.

Conclusions The morphological features of length and depth of the deformity are correlated with psychosocial distress. Nonetheless, these individual features are weak predictors due to their moderate discriminative ability. This underscores that other patient-related factors, such as personality traits, neuropsychological conditions, and other psychosocial influences, are likely to play a role in the occurrence of psychosocial distress. Future studies should investigate these variables alongside the incorporation of standardized instruments for measuring psychosocial distress to better understand and address the distress in this population.
