Socioeconomic disadvantage and its impact on patient satisfaction at a multi-site radiation oncology center.

Purpose: Despite the importance of patient satisfaction (PS) on healthcare outcomes, the factors that influence PS in radiation oncology remain unexplored. This study assesses the influence of socioeconomic status (SES) on PS in radiation oncology, using the Area Deprivation Index (ADI) as a measure of SES. Methods: This single-institution cross-sectional study used the National Research Council (NRC) PS survey at four radiation oncology sites from 2021 to 2023. SES was measured using ADI data from the Neighborhood Atlas. Univariate (UVA) and multivariable (MVA) logistic regression analyses were conducted on recommendation scores (0-10 scale, with 9 or higher indicating a likelihood to recommend). Results: In our analysis of 7,501 survey responses, most patients were female (55.3 %), had curative treatment intent (81.5 %), and were diagnosed with breast cancer (30.4 %), with most being follow-up visits (69.0 %). Average scores for state and national ADI were 3.94 and 50.75, respectively. UVA identified factors such as curative intent (OR 1.68, p < 0.001), follow-up visits (OR 1.69, p < 0.001), and breast cancer diagnosis (OR 1.42, p = 0.018) as enhancing the likelihood of recommending the facility or provider. Those with a national ADI above the mean showed lower propensity to recommend the facility (OR 0.81, p = 0.050) or provider (OR 0.71, p = 0.002). MVA confirmed the significance of national ADI on provider recommendations (OR 0.730, p = 0.005) but not facility recommendations (OR 0.832, p = 0.089). Conclusion: Patients facing higher SES disadvantages are less inclined to recommend their healthcare provider. These results highlight the role of SES in PS assessments and advocate for further investigation into how SES impacts PS and patient-provider relationships.
