Background: Free digital platforms are smartphone-compatible and permit self-directed curriculum development based on learners' interests and educational needs. We developed a free mobile vascular surgery handbook initiated, authored, and edited by surgical house officers and surveyed on the content and users.
Methods: Using a free digital platform, house officers developed a vascular surgery handbook. Initiated by a single user for conference preparation and clinical care, the use expanded through sharing among residents. The handbook was then deployed at a second medical center, with free access granted to users after completing a survey. Handbook and content use were evaluated based on user ratings ≥4 on a Likert scale from 1 to 5, where 1 = "strongly disagree" and 5 = "completely agree." Domains assessed included handbook ease of use, content, and relevance to a variety of learning environments and goals (e.g., preparation for the operating room, rounds, clinic, teaching conferences, and examinations). Analytic methods included qualitative analysis, graphical evaluation, and categorical tests.
Results: The handbook is organized into sections, with each consisting of multiple pages and/or posts related to the section topic. Sections with the most content included lower extremity arterial disease, endovascular aneurysm repair/thoracic endovascular aortic repair, venous disease, anticoagulation, and anatomy/exposures. Fifty-four users participated in the evaluation phase, including different types of surgical residents (35%), medical students (30%), and anesthesia residents (22%). Sixty-nine percent of participants were in their position for <2 years. The average age was 29.1 years, and 57% were women. Preferred learning styles among users at the time of enrollment primarily included question banks (52%), followed by slide-based lectures (15%) and "chalk talk" lectures (13%). Of the users who participated in the presurvey, 43 users participated in the postsurvey with a general agreement on the handbook being an easy-to-use resource that was useful for gaining overall knowledge and contained accurate information. Users generally agreed they would recommend the handbook to a colleague.
Conclusions: References customized to user needs can be developed through crowdsourcing and published with free digital resources. These approaches allow mobile access to useful information during conferences and clinical care. House officers' self-perceived educational needs can be targeted for tailored educational initiatives.
