Short message service (SMS) is easily accessible and potentially an ideal platform for delivering patient-targeted messages. However, an effective SMS dosing strategy is not well established. Our purpose was to evaluate the impact of diabetes self-care promoting messages via non-tailored one-way automated SMS (OASMS) on glycemic control in type 2 diabetes (T2DM). The change in hemoglobin A1c (HbA1c) was compared between patients who received the service and those who did not. This retrospective quasi-experimental pre–post feasibility study was conducted at an academic medical center endocrinology clinic. English-speaking adults (≥18 years) with uncontrolled T2DM (HbA1c ≥ 8%) were included. A total of 69 patients (intervention n = 34; control n = 35) met the inclusion criteria. The mean (±SD) baseline HbA1c values were 10.2% (±1.9%) and 9.9% (±1.7%) in the intervention and control arms, respectively. Median follow-up was 3.3 months (IQR = 3–4.2). An ANCOVA model adjusted for baseline HbA1c and age showed an estimated HbA1c reduction difference of −0.97% (95% CI, −1.73 to −0.20%, p = 0.014), favoring the intervention arm. Inverse propensity score weighting confirmed the ANCOVA results. Our study suggests that adding diabetes self-care promoting messages via non-tailored OASMS to usual care improves glycemic control in poorly controlled T2DM. Larger and longer studies are needed to evaluate different features of the non-tailored OASMS strategy.

回顾性可行性研究：非定制单向自动短消息服务（OASMS）对2型糖尿病患者血糖控制的影响

短消息服务（SMS）易于访问，并且可能是传递以患者为目标的消息的理想平台。但是，有效的SMS剂量策略还不完善。我们的目的是评估通过非定制的单向自动SMS（OASMS）进行的糖尿病自我护理促进信息对2型糖尿病（T2DM）血糖控制的影响。比较接受该服务的患者和未接受该服务的患者血红蛋白A1c（HbA1c）的变化。该回顾性准实验前可行性研究是在学术医学中心内分泌诊所进行的。包括不受控制的T2DM（HbA1c≥8％）的英语成年人（≥18岁）。共有69位患者（干预n = 34；对照组n= 35）符合纳入标准。干预组和对照组的平均HbA1c基线平均值分别为10.2％（±1.9％）和9.9％（±1.7％）。中位随访时间为3.3个月（IQR = 3–4.2）。针对基线HbA1c和年龄进行调整的ANCOVA模型显示，估计的HbA1c减少差异为-0.97％（95％CI，-1.73至-0.20％，p = 0.014），有利于干预组。倾向得分权重的倒数证实了ANCOVA的结果。我们的研究表明，通过非定制的OASMS将糖尿病自我保健促进信息添加到常规保健中可以改善控制不佳的T2DM中的血糖控制。需要更大和更长的研究来评估非定制OASMS策略的不同特征。
