INTRODUCTION: To identify salient patient-reported outcomes related to mental and social health in patients undergoing craniofacial surgery and compare those outcomes with parent proxy reports of the same. We hypothesize that patient and parent proxy reports differ. METHODS: Patients aged 8–17 years undergoing craniofacial surgery between June 2021 and January 2022 and parent proxies completed the following PROMIS domains before and 3 months after surgery: Psychological Stress, Positive Affect, Peer Relationships, Family Relationships, Anxiety. Differences in mean T-scores were compared pre- and postoperatively. Minimal important change (MIC) was defined as a difference of three or more T-score points in the positive or negative direction and represents the threshold above which participants perceived an important difference. RESULTS: Fifty-two participants were identified: 30 declined, 14 were lost to follow-up, and 8 met all study endpoints (n = 4 patients; n = 4 parents). Three PROMIS domains demonstrated an MIC in the patient cohort and two in the parent cohort (Table). Amongst patients, Psychological Stress and Anxiety metrics improved (MIC –3 and –6.5, respectively), whereas perceptions related to Family Relationships worsened (MIC –10.4). Parental perceptions of Positive Affect and Family Relationships worsened (MIC –6.9 and –5.5, respectively). Table. - A Comparison of the Change in PROMIS Ratings by Patients and Parents. PROMIS domain Patient (n = 4) Parent (n = 4) Preoperative, postoperative T-scores (ave.) Change Preoperative, posteroperative T-scores (ave.) Change Psychological stress 56.5, 53.5 –3* 53.2, 55.6 +2.4 Positive affect 49.5, 47 –2.5 48.7, 41.7 –6.9* Peer relationships 50, 48 -2 44, 44.5 +0.5 Family relationships 54, 43.6 –10.4* 52, 46.5 –5.5* Anxiety 56, 49.5 –6.5* 52, 52.4 +0.4 CONCLUSION: Patients reported less stress and anxiety after craniofacial surgery; however, parents perceived a decline in their child’s positive affect. Perceptions related to worsening family relationships correlated between the groups. Additional data are required to determine the strength of the correlation; however, these data call into question who should be making decisions regarding craniofacial care.
