<\/a>Key Points<\/p>\n\n\n\n

Question<\/strong>  Compared with usual care practices, does preoperative education for colorectal surgery aided by 3-dimensional (3D)-printed anatomic models improve the shared decision-making (SDM) experience?<\/p>\n\n\n\n

Findings<\/strong>  In this cluster randomized clinical trial including 51 patients who were counseled for colorectal surgery using either usual care or 3D-printed models, 9-item Shared Decision Making Questionnaire scores showed that the group counseled using 3D-printed models had significantly higher levels of involvement in SDM than the usual care group.<\/p>\n\n\n\n

Meaning<\/strong>  The findings of this study suggest that using 3D-printed models in preoperative counseling for colorectal surgery led to a clinically meaningful improvement in SDM compared with routine care.<\/a><\/p>\n\n\n\n

Abstract<\/p>\n\n\n\n

Importance<\/strong>  Patients undergoing surgery report a lack of involvement in health care decisions and increased anxiety. Three-dimensional (3D)-printed models serve as educational tools to encourage patient engagement, reduce anxiety levels, and aid understanding.<\/p>\n\n\n\n

Objective<\/strong>  To determine the impact of 3D-printed anatomic models on shared decision-making (SDM) and patient anxiety during the preoperative surgical consultation for colon or rectal resection.<\/p>\n\n\n\n

Design, Setting, and Participants<\/strong>  This single-center cluster randomized clinical trial was conducted from March 2022 to June 2023 at a colorectal surgery clinic at an academic medical institution and included adult patients scheduled for partial or complete colon and\/or rectal resection for colorectal cancer, diverticular disease, or inflammatory bowel disease.<\/p>\n\n\n\n

Intervention<\/strong>  Six surgeons (clusters) were randomized to counsel patients using a modular 3D-printed model or providing usual care during preoperative clinic visits.<\/p>\n\n\n\n

Main Outcomes and Measures<\/strong>  The primary outcome was the patient\u2019s perception of involvement in decision-making using the 9-item Shared Decision Making Questionnaire. The secondary outcome was the change in anxiety level measured using the State-Trait Anxiety Inventory. Patient characteristics were compared between the 3D-printed model and usual care arms using a \u03c72<\/sup> test for categorical variables and a t<\/em> test for comparisons between continuous variables.<\/p>\n\n\n\n

Results<\/strong>  Among the 51 patients enrolled (mean [SD] age, 50.7 [14.5] years; 28 female [54.9%]), 28 (54.9%) were in the 3D-printed model arm and 23 (45.1%) were in the usual care arm. Patients counseled with the 3D-printed model reported a significantly higher involvement in SDM compared with those in the usual care group (mean [SD] score, 89.5 [17.6] vs 80.5 [14.4]; P<\/em>\u2009=\u2009.01). Additionally, using a 3D-printed model significantly reduced mean anxiety scores (from 53.5 [SD, 21.2] to 44.1 [SD, 15.8]) compared with conventional methods (from 50.4 [SD, 18.3] to 48.0 [SD, 15.3]) (P<\/em>\u2009=\u2009.04).<\/p>\n\n\n\n

Conclusions and Relevance<\/strong>  This cluster randomized clinical trial found that counseling aided with 3D models during preoperative clinic visits improved SDM among patients undergoing colorectal surgery. This study highlights the potential of 3D-printed models as a tool to enhance patient\u2013clinician collaborations. Given the findings, further research into the effectiveness and implementation of these tools is recommended in more diverse clinical settings.<\/p>\n\n\n\n
