Implementation of written structured feedback into a surgical OSCE

Background Feedback is an essential element of learning. Despite this, students complain about receiving too little feedback in medical examinations, e.g., in an objective structured clinical examination (OSCE). This study aims to implement a written structured feedback tool for use in OSCEs and to analyse the attitudes of students and examiners towards this kind of feedback. Methods The participants were OSCE examiners and third-year medical students. This prospective study was conducted using a multistage design. In the first step, an unstructured interrogation of the examiners formed the basis for developing a feedback tool, which was evaluated and then adopted in the next steps. Results In total, 351 students and 51 examiners participated in this study. A baseline was created for each category of OSCE station and was supplemented with station-specific items. Each of these items was rated on a three-point scale. In addition to the preformulated answer options, each domain had space for individual comments. A total of 87.5% of the students and 91.6% of the examiners agreed or rather agreed that written feedback should continue to be used in upcoming OSCEs. Conclusion The implementation of structured, written feedback in a curricular, summative examination is possible, and examiners and students would like the feedback to be constant.

A Multistage Design Procedure for Planning and Implementing Public Charging Infrastructures for Electric Vehicles

Presented in this paper is a Multistage Design Procedure (MSDP) for planning and implementing Public Charging Infrastructures (PCIs) to satisfy intracity charging demand of Electric Vehicles (EVs). The proposed MSDP splits planning and design processes into multiple stages, from macroscale to fine-scale levels. Consequently, the preliminary results achieved at each stage can be refined at the subsequent stages, leading to determine the accurate number and precise geographical location of each charging point. The main advantage of the proposed approach is that it splits a very complicated procedure into multiple and simpler stages, at each of which appropriate goals, targets and constraints can be included. As a result, the iterative interactions among all the stakeholders involved in the PCI design process are significantly simplified. The proposed MSDP has been employed in the planning and design of the PCI of the Italian island of Sardinia, accordingly to all the public bodies.

Tobacco Advertisements: What Messages Are They Sending in African American Communities?

Racial disparities in tobacco-related death and disease persist. Despite evidence of disparities in exposure to tobacco retailers and point-of-sale advertising, little is known about the extent to which tobacco advertisements within African American communities use three prominent messaging strategies: reassure use is safe despite health risks, redirect attention from health risks to other product features, or incite bravery to use despite health risks. Using a multistage design, we examined tobacco advertisements at 24 retail stores listed on Countertools.org StoreMapper within 15 census tracts where roughly 74% of the population was African American. After confirming interrater reliability, trained data collectors assessed messaging strategy (reassurance, misdirection of attention, or inducement to bravery) usage in ads (n = 165) for various brands (e.g., Newport, Swisher Sweets, Blu) and whether strategies varied by product type (e.g., cigarettes, nonlarge cigar, e-cigarettes). Chi-square analysis of 165 advertisements revealed that the misdirection of attention strategy was used more often than reassurance or inducement to bravery. Tobacco advertisement messaging strategies also varied by product type, with misdirection of attention used more frequently in cigarette and nonlarge cigar advertisements and reassurance used more frequently in e-cigarette advertisements. Cigarette and nonlarge cigar advertisement messages prey on African American communities by redirecting their focus from consequences toward favorable product attributes. Additionally, reassurance messaging may misconstrue risks associated with e-cigarettes; therefore, we should vigilantly monitor e-cigarette trends among this population. Countering misleading messages and advocating policies regarding advertisement content and density within African American communities could help reduce health disparities.
