ABSTRACT
BACKGROUND: Endocrine surgery (ES) is a relatively young subspecialty of general surgery, and prior research has shown low public awareness of these specialists' roles. We hypothesized that a video-based intervention could increase public knowledge of the specialty in an effective and efficient manner. METHODS: Participants were recruited at three public locations (a farmer's market, a public park, and a university hospital) and were given a three-question survey to assess baseline knowledge of ES. They then watched one of two video-based educational interventions and completed an identical postintervention survey. Two surveyors recruited 80 individuals per site, with 40 participants in each intervention group. Participants' sex and age and whether or not they were on clinical staff at the University of Alabama at Birmingham were recorded. RESULTS: A total of 240 participants were recruited; 61.3% female with median age 40 y. Preintervention, only 42.1% of participants could correctly define ES. ES were confused with endocrinologists by 44.6%, which was not different between sites (P = 0.09). Significantly, more participants at all sites could correctly define ES postintervention (67.9% versus 42.1%; P < 0.001). Clinical staff did not perform better than the lay public at any location (P = 0.32). The long video had a significantly greater increase in correct responses compared with the short video overall (32.5% versus 19.1%; P < 0.001) and at each location. CONCLUSIONS: This study confirms the public's general lack of knowledge about ES and their scope of practice. A video-based intervention was successful in improving knowledge of the practice of ES, with a longer, explanatory video being most effective.
