Abstract
BACKGROUND: We investigated whether partner (spouse or intimate partner) engagement in colorectal cancer (CRC) surveillance is associated with patient receipt of surveillance. METHODS: From 2019 to 2020 we surveyed Stage III CRC survivors diagnosed 2014-2018 at an academic cancer center, a community oncology practice and the Georgia SEER registry, and their partners. Partner engagement was measured across 3 domains: Informed about; Involved in; and Aware of patient preferences around surveillance. We evaluated bivariate associations between domains of partner engagement and independent partner variables. Analysis of variance and multivariable logistic regression were used to compare domains of engagement with patient-reported receipt of surveillance. RESULTS: 501 patients responded (51% response rate); 428 had partners. 311 partners responded (73% response rate). Partners were engaged across all domains. Engagement varied by sociodemographics. Greater partner involvement was associated with decreased odds of receipt of composite surveillance (OR 0.67, 95% CI 0.48-0.93) and trended towards significance for decreased odds of receipt of endoscopy (OR 0.60, 95% CI 0.34-1.03) and CEA (OR 0.75, 95% CI 0.55-1.04). Greater partner awareness was associated with increased odds of patients' receipt of endoscopy (OR 2.18, 95% CI 1.15-4.12) and trended towards significance for increased odds of receipt of composite surveillance (OR 1.30, 95% CI 0.91-2.04). CONCLUSION: Partners are engaged (informed, involved, and aware) in CRC surveillance. Future research to develop dyadic interventions that capitalize on the positive aspects of partner engagement may help partners effectively engage in surveillance to improve patient care.
