Supplementary Material for: Surgical Preferences and Fears: Misconceptions About Robotic-Assisted Surgery

Introduction and objective
Robotic-assisted surgery (RAS) is widely adopted across surgical fields, notably urology, but patient knowledge remains limited, often shaped by misconceptions. Previous research indicates factors like age, profession, and technology use influence RAS perceptions. This study investigates public knowledge, preferences, and misconceptions about RAS within a German cohort.
Methods
A cross-sectional survey at a university hospital’s open house gathered responses from 339 participants prior to an RAS exhibition. The questionnaire assessed demographics, surgical preferences, and RAS knowledge. Statistical analyses, including t-tests, chi-squared tests, ANOVA, and multivariate logistic regression, identified key associations.
Results
Results showed 71% (234) of participants favored RAS over conventional surgery, yet misconceptions persisted in 38% (122), particularly among pensioners (48% (46) , p < 0.01). Misconceptions were linked to a preference for conventional surgery (43% (52) vs. 19% (36), p < 0.01). Surgical preference emerged as a significant predictor of misconception. Concerns included surgeon skill (41%, 141) and machine malfunction (39%, 132), with younger participants fearing human error and older individuals fearing technical failure (p < 0.01).
Conclusion
This local study reveals strong public support for RAS but underscores prevalent misconceptions, especially among older adults, suggesting that addressing misconceptions could foster acceptance and informed decision-making.
