Objective: Collaborative writing applications (CWAs), such as the Google Docs TM platform, can improve skill acquisition, knowledge retention, and collaboration in medical education. Using CWAs to support the training of residents offers many advantages, but stimulating them to contribute remains challenging. The purpose of this study was to identify emergency medicine (EM) residents' beliefs about their intention to contribute summaries of landmark articles to a Google Docs TM slideshow while studying for their RoyalCollege of Physicians and Surgeons of Canada (RCPSC) certification exam. Method: Using the Theory of Planned Behavior, the authors interviewed graduating RCPSC EM residents about contributing to a slideshow. Residents were asked about behavioral beliefs (advantages/disadvantages), normative beliefs (positive/negative referents), and control beliefs (barriers/facilitators). Two reviewers independently performed qualitative content analysis of interview transcripts to identify salient beliefs in relation to the defined behaviors.Results: Of 150 eligible EM residents, 25 participated. The main reported advantage of contributing to the online slideshow was learning consolidation (n = 15); the main reported disadvantage was information overload (n = 3). The most frequently reported favorable referents were graduating EM residents writing the certification exam (n = 16). Few participants (n = 3) perceived any negative referents. The most frequently reported facilitator was peerreviewed high-quality scientific information (n = 9); and the most frequently reported barrier was time constraints (n = 22). Conclusion: Salient beliefs exist regarding EM residents' intention to contribute content to an online collaborative writing project using a Google Docs TM slideshow. Overall, participants perceived more advantages than disadvantages to contributing and believed that this initiative would receive wide support. However, participants reported several barriers that need to be addressed to increase contributions. Our intention is for the beliefs identified in this study to contribute to the design of a theory-based questionnaire to explore determinants of residents' intentions to contribute to an online collaborative writing project. This will help develop implementation strategies for increasing contributions to other CWAs in medical education. RÉSUMÉObjectif: Les applications d'écriture collective (AEC), telles que la plateforme Google Docs TM , peuvent améliorer l'acquisition des compétences, la conservation du savoir et la collaboration en formation médicale. Ainsi, les AEC utilisées à l'appui de la formation donnée aux résidents offrent de nombreux avantages, mais la contribution au contenu relève du défi. L'étude décrite ici avait pour but de recueillir l'opinion des résidents en médecine d'urgence (MU) sur leur intention de présenter des résumés d'article novateur dans un diaporama Google Docs pendant qu'ils se préparaient à leur examen de certification du Collège royal des médecins et chirurgiens ...

SUMMARY. Six patients are reported who had multiple tumours confined to areas of skin irradiated between 11 and 28 years previously. They had received radiotherapy for ankylosing spondylitis in 5 cases and lichen planus in 1. In 3 patients the x‐rays had produced radiation damage and multiple basal‐cell epitheliomata. In 3 there was no overt skin damage and in these premalignant fibro‐epitheliomata were more common. Skin tumours must be added to the growing number of cancers from which patients with ankylosing spondylitis may suffer as a result of previous radiotherapy.
