The effects of psychosocial determinants on post-operative complications of head and neck free flap patients.

PURPOSE: Not much is known about how pre-operative psychosocial factors affect head and neck free flap outcomes. Hence, the objective of the study is to determine if a patient's pre-operative self-perception and quality of life affect post-operative complications and hospital length of stay after free flap surgery.

MATERIALS AND

METHODS

This was a prospective cohort study. Patients who underwent a free flap surgery at an academic tertiary care center between January 2021 and March 2022 were asked to fill out the Rosenberg Self Esteem Scale and the Short Form 36 Health Questionnaire before surgery. A chart review of their medical records was then performed. Analysis of the data was performed using Spearman Correlation, Fisher exact test, Mann-Whitney and Multivariate Logistic Regression on STATA 15.

RESULTS

Sixty-one patients (73.8 % male; mean [SD; range] age: 60.9 [14.0, 23.1-86.8]) who underwent free flap surgery agreed to participate in the study. Most of the participants were not Caucasian (59 %). The most common indication for surgery was malignancy (93 %). The post-operative complication rate was 34.4 % and included 3 hematoma (4.9 %), 3 free flap failure (4.9 %), 9 wound dehiscence (14.8 %), 10 salivary fistulas (16.4 %), and 3 aspiration pneumonia or chyle leak (4.9 %). There were no mortalities. The mean role limitations due to physical health subscore [SD; range], social functioning subscore, pain subscore, and general health subscore of the SF-36 were 61.9 [39.2, 0-100], 70.7 [27.5, 0-100], 62.1 [25.7, 0-100], and 67.8 [20.3, 20-100], respectively. On univariate analysis, decreased physical limitations, better social functioning, less pain and better general health were associated with fewer overall post-operative complications, but was not correlated with length of stay. This held true for social functioning and general health even in multivariate analysis accounting for age and smoking history. The mean Rosenberg Self Esteem Scale score was 24.3 [4.1, 13-30].

CONCLUSIONS

In this study, patients with more limited social function and worse general health had more overall post-operative complications. It is important to continue to explore how pre-operative quality of life and other psychosocial factors can affect surgical outcomes.
