DCT should be balanced with accessibility and data reliability while meeting regulatory requirements. Here, we conducted a pilot study for functional constipation symptoms to investigate the feasibility of DCT. The study was an open, fully remote, randomized clinical trial in participants who had functional constipation symptoms. Electronic consent was obtained remotely, and study volunteers were screened through web\u2010based questionnaires. Subjects were randomized to either receive <jats:italic>Lactobacillus<\/jats:italic> and vitamin C supplements or vitamin C alone in a 1:1 ratio, which were delivered directly to subjects. Subjects kept track of bowel diaries daily during the 1\u2010week baseline and 2\u2010week treatment period using mobile applications. Bowel symptoms and the validity of the records were descriptively evaluated. A total of 30 subjects were randomized and completed the study. A total of 26.7% of subjects resided outside of the metropolitan area. Two\u2010week <jats:italic>Lactobacillus<\/jats:italic> treatments increased the number of defecations (+0.80 vs. +0.46 times per week) and decreased the defecation time (\u22123.94\u2009h vs. \u22121.62\u2009h) compared to the comparator group. Overall, 67.1% of bowel diary records were completed in accordance with the schedule whereas 32.9% were not. Implementation of DCTs can facilitate geographic accessibility but should be guaranteed for data reliability. Prompt detection of errors and response using objective metrics would be required.<\/jats:p>","DOI":"10.1111\/cts.13617","type":"journal-article","created":{"date-parts":[[2023,8,26]],"date-time":"2023-08-26T06:14:10Z","timestamp":1693030450000},"page":"2177-2188","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Feasibility
