Central to this transformation is 'digitization,' which converts continuous analog data into a discrete digital form. However, this process is challenging. First, digitization inherently has the potential to introduce information loss, thereby diminishing the richness and complexity of data. Second, \"digit bias,\" a cognitive distortion, emerges in the interpretation phase, where individuals' perceptions of and reactions to digital data are intrinsically skewed. There exist two major cognitive biases during digitization process: \"digit preferences,\" where healthcare providers prioritize specific numbers, and \"left digit bias\" where continuous variables are disproportionately estimated by focusing on the leftmost digit. Although information loss and cognitive biases can cause significant distortions in healthcare, the effects of this \"digitization\" process have not been adequately quantified, and the accumulation of further evidence in this field is anticipated.</p>","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"2090-2099"},"PeriodicalIF":1.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142780215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to develop and validate a Japanese version of the Assessing Competency in EBM (ACE) tool. Methods We translated the ACE tool into Japanese, following international standards, and distributed it online to 99 healthcare professionals and students. The participants completed demographic questions and the Japanese version of the ACE tool. A subset also completed the retest and Fresno test. Internal consistency was assessed using Cronbach's alpha, test-retest reliability using the intraclass correlation coefficient (ICC), and construct validity using a confirmatory factor analysis and correlation with the Fresno test. Results The Japanese version of the ACE tool showed a low internal consistency (Cronbach's alpha =0.31, 95% CI: 0.09-0.49), but an acceptable test-retest reliability (ICC =0.64, 95% CI: 0.40-0.81). A confirmatory factor analysis provided moderate support for the structure of the tool (SRMR =0.092, RMSEA =0.048, CFI =0.852). The tool demonstrated a moderate correlation with the Fresno test (r =0.35). The median completion time was 847 s (IQR, 577-1,249 s). Conclusion Although the Japanese version of the ACE tool showed some promising aspects, including a quick administration and partial validity, its low internal consistency suggests that refinement is needed before it can be confidently used in Japanese medical education settings. Future studies should focus on improving the tool's reliability, potentially through in-person administration, to develop a robust EBM assessment tool in the Japanese healthcare context.</p>","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"2136-2142"},"PeriodicalIF":1.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142894445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, detailed and long-term follow-up reports of both efficacy and safety remain insufficient. We conducted a case-series analysis of patients with migraine who switched from galcanezumab to erenumab, both belonging to the class of CGRP mAbs. Methods We conducted a single-center retrospective real-world study. Patients with migraine who first received galcanezumab for ≥3 months and then switched to erenumab at Keio University Hospital were enrolled to investigate changes in monthly migraine days (MMD), response rate, and adverse effects (e.g., injection-site reactions). Additionally, we performed a narrative review of the literature on switching CGRP mAbs. Results Among the nine patients enrolled, the 50% response rate for MMD was 33% at 3 months after switching. Two patients (22%) initially responded at the 3-month assessment, but later reverted to baseline MMD levels. Switching from galcanezumab to erenumab increased the frequency of constipation, which was typically managed using laxatives. Participants who experienced injection-site reactions tended to exhibit similar reactions regardless of the type of CGRP mAb used. Five patients (56%) demonstrated an improvement in satisfaction after erenumab initiation at least once. A literature review revealed that the characteristics of the cohorts varied among studies. Conclusion Switching from galcanezumab to erenumab was effective in some patients, while it was associated with some tolerable side effects, and it improved patient satisfaction in approximately half of the patients, despite interindividual diversity in responses and fluctuating responses after switching, which warrants further investigation.</p>","PeriodicalId":13719,"journal":{"name":"Internal Medicine","volume":" ","pages":"2114-2123"},"PeriodicalIF":1.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142931832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
