目的 调查造血干细胞移植出院患者的社会支持现状，寻求相应的护理对策，帮助患者保持较高的社会支持水平。 方法 选择2007年9月-2009年3月在层流病房进行造血干细胞移植的患者48例，采用肖水源的社会支持评定量表，进行住院期间和出院3个月后的问卷调查，并进行统计学分析。 结果 患者住院期间社会支持总分为(41.40±5.60)分，出院3个月后社会支持总分为(38.19±3.65)分，比较具有统计学意义(Plt;0.05)。 结论 造血干细胞移植患者出院后社会支持水平降低，护士应加强对造血干细胞移植患者出院后的指导，拓宽造血干细胞移植出院患者社会支持渠道，帮助患者保持较高的社会支持水平，从而促进患者的康复。
Patient reported outcome measures (PROM) are widely used in clinical research and practice. To aid the interpretation of PROM, researchers have proposed the minimal important difference (MID), the smallest change or difference that patients perceive as important. However, the estimation methods of MID are numerous and inconsistent, which brings difficulties to selecting the optimal MID estimate to interpret PROM results. To address this issue, a research team from McMaster University in Canada has proposed an approach for selecting the optimal MID. This method includes three core steps: evaluating the credibility of MID estimates, assessing the consistency among credible MID estimates, and selecting the optimal value based on contextual factors. The credibility evaluation instrument for anchor-based MID examines five core criteria, including the data sources of PROM and anchor, the interpretability of anchor, the correlation between anchor and PROM, the precision of MID estimates, and the judgment of anchor thresholds. When there are multiple credible MID estimates, the optimal MID estimate is selected by evaluating the consistency among the estimates and considering contextual factors that affect the variability among the estimates, such as the type of intervention, follow-up time, and disease severity. In addition, the team provided recommendations to improve the reporting quality of MID studies. This article provides a detailed introduction and interpretation of these developments, aiming to enhance researchers' and clinicians' understanding and application of MID, thereby supporting clinical research and healthcare decision-making.
