This paper reports a follow-up of previous meta-analysis research conducted by the author on the effects of diabetes patient education on patient outcomes. An expanded sample of studies and psychological outcome variables were added to the previously studied variables of patient knowledge, self-care behaviors (compliance and skill performance) and metabolic control. The purpose was to determine: (1) the effects of patient education on specific outcome variables; and (2) the relationships between effects of education and characteristics of the studies and/or subjects. Following an extensive literature search, a total of 82 studies were found which met the inclusion criteria for this analysis; 68% were published and 32% were unpublished. Homogeneity analyses of specific patient outcome variables yielded the following results: knowledge effects ranged from 0.49 to 1.05; self-care behavior effects from 0.17 to 0.57, with insulin injection and weight loss associated with the smallest effect sizes; metabolic control from 0.16 to 0.41; and psychological outcomes 0.27. Mean age of the subjects was negatively correlated with knowledge and cholesterol, indicating that the older the mean age of the subjects, the lower the effects of patient education on these variables. Findings of this meta-analysis on the expanded data set were consistent with the previous meta-analysis and lend support to the effectiveness of diabetes patient education in improving patient outcomes.
本文报告了作者之前对糖尿病患者教育对患者结局影响的荟萃分析研究的后续情况。在先前研究的患者知识、自我护理行为（依从性和技能表现）以及代谢控制等变量基础上，增加了研究样本和心理结局变量。目的是确定：（1）患者教育对特定结局变量的影响；（2）教育效果与研究和/或受试者特征之间的关系。经过广泛的文献检索，共找到82项符合本分析纳入标准的研究；其中68%已发表，32%未发表。对特定患者结局变量的同质性分析得出以下结果：知识效果范围为0.49至1.05；自我护理行为效果为0.17至0.57，胰岛素注射和体重减轻的效果量最小；代谢控制为0.16至0.41；心理结局为0.27。受试者的平均年龄与知识和胆固醇呈负相关，表明受试者的平均年龄越大，患者教育对这些变量的影响越低。对扩展数据集的这项荟萃分析结果与之前的荟萃分析一致，支持了糖尿病患者教育在改善患者结局方面的有效性。
