Japanese physicians face difficulties in conducting clinical research. One of the reasons is the lack of knowledge in designing and conducting clinical research. In undergraduate and postgraduate education, or continuing professional development, most Japanese physicians are untrained for clinical research. Some exceptions are the basic laboratory training received by undergraduates, or when students opt to study for a PhD after graduation ( Fukuhara S, Sakushima K, 2012). In the past, many physicians went to graduate school to learn research methods, but in recent years, fewer doctors have followed this path. One of the reasons is that graduate students are forced to work for very low pay, or for no pay at all, at university hospitals ( Shibuya and Unno, 2019).

One solution would be to equip a large number of non-academic physicians without research skills, as they are interested in the research itself ( Kurita et al., 2016). We have conducted various workshops with the aim of increasing research output. In this article, we would like to introduce the contents of a workshop for beginners and share the lessons learned from it.

Writing letters to the editor based on critical appraisal can serve as the first step in scholarly activity. The reasons are as follows. First, critical appraisal of existing research is essential when developing a new clinical study. Second, novices can easily gain experience of journal submission. Third, the time it takes to write a letter, and its submission process, is shorter than it is for original research. However, there are few opportunities to learn how to write these letters in Japan ( Kataoka et al., 2018). Therefore, the aim of the workshop was to educate physicians about how to write letters to the editor.

We conducted this workshop as a part of the Annual Meeting of the Japan Chapter of the American College of Physicians in Kyoto, Japan, in 2018. Participants were physicians and medical students who chose to join this workshop. Workshop facilitators included four residents, four prior-participants of this workshop, and two Master of Public Health. They were all Japanese physicians.

Twenty-eight participants, including 3 medical students, attended the workshop and were randomly divided into 7 groups for group activities. Twenty-five participants completed the post-workshop questionnaire, while 3 attendees completed it but refused to be included in the analysis. Participants’ satisfaction with the workshop had a mean of 4.5 points (standard deviation: 0.5) out of 5. In the self-evaluation, 17 participants (77%) responded that they could now explain falsificationism; 18 participants (81%) stated that they could explain how to check author instructions; and 19 participants (86%) answered that they now could explain how to write a letter to the editor. Four participants’ groups submitted within a month after the workshop. A total of 13 authors across 4 groups ultimately had letters publishedin the Annals of Internal Medicine ( Table 2). In addition, none of the first authors of each letter had previously written a clinical research paper.

We conducted a brief workshop that was focused on educating physicians on how to write letters to the editor. Participants reported being well satisfied with the workshop, and following the workshop, approximately half of the participants had their letters published.

The strength of this workshop was that it improved not only the participants’ knowledge but it also led to the concrete result of four published letters in the Annals of Internal Medicine ( Kirkpatrick and Kirkpatrick, 2016). Similar short-term research workshops usually improve knowledge levels, but not results. We think that this difference was made by focusing on the letter to the editor, a type of scholarly activity that produces short-term results.

There are two areas of improvement that should be made to the design of the workshop. First, the topic of the analyzed article was difficult for Japanese participants to understand due to differences between the medical systems. Therefore, we should choose a more familiar topic for participants in future workshops. Second, we could not share information about errors in the journal submission system prior to submission, which led to submissions taking extra time. We could not share the error information immediately. The delay of information sharing for the remote follow remains a problem to be solved in future. Despite these limitations, this workshop appears to be beneficial for Japanese physicians with insufficient knowledge regarding clinical research ( Kataoka et al., 2019).

Based on these initial findings, we launched an e-learning site to scale-up the project. Participants can subscribe to watch lecture videos including other scholarly activities (e.g. time management, how to write and conduct systematic review, and how to write a protocol of prediction model study). The number of participants who can receive feedback is limited due to a lack of manpower. We are recruiting participants who want to become “feedback providers” (i.e., research mentors) through the site.

Our workshop was effective in educating Japanese physicians about how to use this framework to write letters to the editor. All of the learning outcomes established for the workshop were successful, and 13 participants across 4 groups had their letters published in the Annals of Internal Medicine. Further investigation to scale up this workshop is warranted.
