To explore the impact of education and target-setting on the life stories of patients with diabetes up to 10 years after they had participated in the Dose Adjustment for Normal Eating programme (DAFNE).
Qualitative, semi-structured interviews were conducted before and after DAFNE courses to elicit narrative accounts from participants at three UK education centres. Observations of courses also took place. Data were gathered from 21 participants over 32 interviews and 146 h of observations, and analysed using a narrative approach.
Findings suggest that patient education can create positive transformations in the lives of people with diabetes in ways that are not fully captured by simple quality-of-life scores. However, a review of evidence from other studies shows that DAFNE-recommended blood glucose results are in fact out of reach of even these most motivated and well-informed patients. This information was not shared with DAFNE attendees, who were expected to aim for near-normal HbA1c levels. After the course, participants sometimes perceived themselves as failing in their efforts, even when they had better than average blood glucose results.
Specific and measurable low HbA1c targets may be desirable for reducing the risk of complications in diabetes, but they are not attainable or realistic even for most DAFNE graduates. It is suggested that setting goals without information about how achievable they really are could be counterproductive in terms of supporting and maintaining patient self-efficacy long-term.
探讨教育和目标设定对参加正常饮食剂量调整计划(DAFNE)长达10年的糖尿病患者生活经历的影响。
在DAFNE课程前后进行了定性、半结构化访谈,以获取英国三个教育中心参与者的叙述性记录。还对课程进行了观察。通过32次访谈和146小时的观察收集了21名参与者的数据,并采用叙述性方法进行分析。
研究结果表明,患者教育能够以简单生活质量评分无法完全体现的方式,给糖尿病患者的生活带来积极转变。然而,对其他研究证据的回顾显示,即使是这些最积极主动且信息充分的患者,实际上也无法达到DAFNE推荐的血糖结果。这一信息并未告知DAFNE的参与者,他们被期望将目标设定为接近正常的糖化血红蛋白水平。课程结束后,参与者有时会觉得自己的努力失败了,即便他们的血糖结果优于平均水平。
设定具体且可衡量的低糖化血红蛋白目标可能有助于降低糖尿病并发症风险,但即使对大多数完成DAFNE课程的人来说,这些目标也无法实现或不切实际。建议在没有告知目标实际可实现程度的情况下设定目标,从长期支持和维持患者自我效能感的角度来看,可能会适得其反。
