To investigate the impact of an electronic medical record management system (EMRMS) on disease activity and the frequency of outpatient visits among patients with ankylosing spondylitis (AS). We identified 652 patients with AS who were followed up for at least 1 year before and after the first Ankylosing Spondylitis Disease Activity Score (ASDAS) assessment and compared the number of outpatient visits and average visit time within 1 year before and after the initial ASDAS assessment. Finally, we analyzed 201 patients with AS who had complete data and received ≥ 3 continuous ASDAS assessments at an interval of 3 months, and we compared the results of the second and third ASDAS assessments with those of the first. The number of annual outpatient visits increased after ASDAS assessment (4.0 (4.0, 7.0) vs. 4.0 (4.0, 8.0), p < 0.001), particularly among those with a high initial disease activity. The average visit time was reduced within 1 year after ASDAS assessment (6.4 (8.5, 11.2) vs. 6.3 (8.3, 10.8) min, p = 0.073), especially among patients whose with an inactive disease activity was < 1.3 (ASDAS C-reactive protein (CRP) 6.7 (8.8, 11.1) vs. 6.1 (8.0, 10.3) min, p = 0.033; ASDAS erythrocyte sedimentation rate (ESR) 6.4 (8.7, 11.1) vs. 6.1 (8.1, 10.0) min, p = 0.027). Among patients who received at least three ASDAS assessments, the third ASDAS-CRP tended to be lower than the first (1.5 (0.9, 2.1) vs. 1.4 (0.8, 1.9), p = 0.058). The use of an EMRMS increased the frequency of ambulatory visits among AS patients with high and very high disease activity and reduced the visit time among those with an inactive disease. Continual ASDAS assessments may help control the disease activity of patients with AS.

调查电子病历管理系统 (EMRMS) 对强直性脊柱炎 (AS) 患者疾病活动度和门诊就诊频率的影响。我们确定了 652 名 AS 患者，他们在第一次强直性脊柱炎疾病活动评分 (ASDAS) 评估前后至少随访了 1 年，并比较了初次 ASDAS 评估前后 1 年内的门诊就诊次数和平均就诊时间. 最后，我们分析了201例数据完整且间隔3个月连续接受≥3次ASDAS评估的AS患者，并将第二次和第三次ASDAS评估的结果与第一次进行比较。ASDAS 评估后年度门诊就诊人数增加 (4.0 (4.0, 7.0) 对比 4.0 (4.0, 8.0)，p < 0.001)，尤其是那些初始疾病活动度高的人群。ASDAS 评估后 1 年内平均就诊时间减少（6.4（8.5，11.2）与 6.3（8.3，10.8）分钟，p  = 0.073），尤其是在非活动性疾病活动度 < 1.3 的患者中（ASDAS C-反应蛋白 (CRP) 6.7 (8.8, 11.1) 与 6.1 (8.0, 10.3) 分钟，p  = 0.033；ASDAS 红细胞沉降率 (ESR) 6.4 (8.7, 11.1) 与 6.1 (8.1, 10.0) 分钟，p  = 0.027）。在接受至少三次 ASDAS 评估的患者中，第三次 ASDAS-CRP 往往低于第一次 (1.5 (0.9, 2.1) vs. 1.4 (0.8, 1.9)，p = 0.058）。EMRMS 的使用增加了疾病活动度高和非常高的 AS 患者门诊就诊的频率，并减少了非活动性疾病患者的就诊时间。持续的 ASDAS 评估可能有助于控制 AS 患者的疾病活动。
