Assessing the Risk of Adjuvant Radiotherapy Initiation Delays With Social Support Surveys

Abstract

AbstractObjectiveIn patients with head and neck squamous cell carcinoma (HNSCC), initiating postoperative radiotherapy (PORT) greater than 42 days after surgery is associated with a higher risk of poor survival outcomes. Social support has been shown to modulate behaviors related to care‐seeking and treatment adherence. In this study, we sought to determine the relationship between social support metrics and PORT delays.Study DesignProspective cohort study.SettingSingle tertiary medical center.MethodsPatients with HNSCC who underwent primary surgical excision requiring PORT were prospectively enrolled. Patient‐perceived social support metrics were assessed using the Medical Outcomes Study Social Support Survey (MOS‐SSS) at initial presurgical evaluation. Associations with PORT delays were evaluated via univariable and multivariable logistic regression analysis.ResultsA total of 111 patients met the inclusion criteria for the study. An additional 28 patients were recommended to receive PORT but did not initiate treatment and were included for secondary analysis. All four subscales of the MOS‐SSS (positive social interaction, affectionate support, tangible support, and emotional/informational support) were significantly associated with PORT initiation delays on univariable analysis. On multivariable analysis, the overall MOS‐SSS score (odds ratio [OR] 2.08, 1.15‐4.35, p = .028) was significantly associated with PORT initiation delays. On secondary analysis, lower tangible support was associated with a lack of PORT initiation (OR 1.63, 1.05‐2.54, p = .028).ConclusionSocial support metrics were significantly associated with PORT delays, which may help promote tighter scheduling and closer monitoring of high‐risk patients.
