炎症性肠病（IBD）患者易感染、易骨折和易得皮肤癌等。我们以患者为中心的方法开发了预防健康视频，并测试了其对预防健康采纳的影响。我们通过患者为中心的焦点小组和访谈的迭代开发了五部动画视频来解释IBD中的预防健康建议。随后，在基于网络的IBD队列中进行了一项随机对照试验，以测试视频教育干预和仅文本干预的影响。主要结果指标为接种流感疫苗，次要结果指标包括接受其他预防健康服务的意愿。我们通过患者的意见开发了五部动画视频。然后，共有1056名IBD患者被随机分配到接收视频（n=511）或仅文本（n=545）干预的组别；视频组中有55％（281/511）的人和文本组中有57％（311/545）的人在上一年接种了流感疫苗。 干预后立即，73％（502/683）的患者表示有意接种疫苗，其中不同干预类型之间没有差异（视频组75％（231/307），文本组72％（271/376））。在干预后，实际接种流感疫苗的患者比例也不因通知类型而不同（P=0.07）。接种流感疫苗的意愿和实际接种疫苗的最强预测因素均为先前接种过流感疫苗。年龄较大也与接种意愿（36-75岁相对于18-35岁；P=0.006）和接种实际（>75岁相对于18-35岁；P=0.05）有更高的可能性。两组患者接种流感疫苗的比例都较高，但在接种意愿或预防健康建议的不同信息类型中没有差异。值得注意的是，两组患者中有一部分意­愿施打疫苗，但最终未实际接种。需要进一步评估患者教育策略，以提高IBD患者对预防健康的采纳。ClinicalTrials.gov NCT05997537；https://clinicaltrials.gov/ct2/show/NCT05997537。©Millie D Long, Welmoed K van Deen, Laura Weisbein, Carine Khalil, Keren L Appel, Xian Zhang, Wenli Chen, Lori Zubrod, Robbie Maris, Afsoon Ghafari, Taylor Dupuy, Christina Y Ha, Brennan M R Spiegel, Christopher V Almario, Gil Y Melmed。原始出版物发表于《医学互联网研究杂志》（https://www.jmir.org），23.08.2023。

Patients with inflammatory bowel disease (IBD) are at increased risk of infections, bone fractures, and skin cancers.We developed preventive health videos using a patient-centered approach and tested their impact on preventive health uptake.Five animated videos explaining preventive health recommendations in IBD were iteratively developed with patient-centered focus groups and interviews. A randomized controlled trial was then conducted in a web-based IBD cohort to test the impact of video- versus text-based educational interventions. The primary outcome was receipt of the influenza vaccine. Secondary outcomes included intention to receive other preventive health services.Five animated videos were developed with patient input. A total of 1056 patients with IBD were then randomized to receive the video (n=511) or text-only (n=545) interventions; 55% (281/511) of the video group and 57% (311/545) of the text-only group had received their influenza vaccine in the prior year. Immediately after the intervention, 73% (502/683) of patients reported their intention to receive the vaccine, with no difference by the type of intervention (75%, 231/307, for the video group and 72%, 271/376, for the text-only group). The proportion of patients who actually received the influenza vaccine after the intervention also did not differ by messaging type (P=.07). The strongest predictor of both intention to receive and actual receipt of the influenza vaccine was prior influenza vaccination. Older age was also associated with a higher likelihood of the intention to receive (age 36-75 years relative to 18-35 years; P=.006) and actual receipt (age >75 years relative to 18-35 years; P=.05) of the influenza vaccine.The proportion of patients receiving the influenza vaccine was high in both groups, but there was no difference in receipt of or in the intention to receive preventive health recommendations by type of messaging. Notably, a portion of patients in both groups had intended to be vaccinated but did not ultimately receive the vaccine. Further evaluation of patient-education strategies is warranted to improve preventive health uptake among patients with IBD.ClinicalTrials.gov NCT05997537; https://clinicaltrials.gov/ct2/show/NCT05997537.©Millie D Long, Welmoed K van Deen, Laura Weisbein, Carine Khalil, Keren L Appel, Xian Zhang, Wenli Chen, Lori Zubrod, Robbie Maris, Afsoon Ghafari, Taylor Dupuy, Christina Y Ha, Brennan M R Spiegel, Christopher V Almario, Gil Y Melmed.
