Abstract: Objective　To explore the effect of the management mode based on the smart medical system in the prevention of lymphedema in breast cancer patients after surgery. Methods　A total of 112 female breast cancer patients admitted to Wuxi Second People's Hospital from January to December 2020 were selected and divided into an observation group and a control group by the random number table method, with 56 cases in each group. The control group were (45.37±6.58) years old, and took conventional management mode. The observation group were (45.52±6.43) years old, and took the management mode based on the smart medical system. The lymphedema knowledge awareness rates, lymphedema prevention behaviors, and incidences of lymphedema were compared between these two groups. The enumeration data were compared between these two groups by χ² test, and the measurement data by independent-sample t test. Results　The awareness rates of disease causes, clinical manifestations, treatment methods, risk factors, and prevention methods in the knowledge of lymphedema after the intervention were 83.93% (47/56), 89.29% (50/56), 92.86% (52/56), 83.93% (47/56), and 87.50% (49.56) in the observation group, and were 66.07% (37/56), 69.64% (39/56), 76.79% (43/ 56), 67.86% (38/56), and 69.64% (39/56) in the control group, with statistical differences between these two groups (all P<0.05). The scores of skin treatment, life style, and avoiding upper limb pression and extreme temperature after the intervention in the observation group were higher than those in the control group (all P<0.001). The behavioral score of mastering lymphedema prevention in the observation group was higher than that in the control group after the intervention [(61.99±3.28) vs. (50.44± 4.20), P<0.05]. The incidence of lymphedema after the intervention was 8.93% (5/56) in the observation group, and was 23.21% (13/56) in the control group, with a statistical difference (χ²=4.236, P=0.040). Conclusion　Applying the management mode based on the smart medical system in patients after breast cancer surgery can significantly improve their cognitive level of lymphedema and preventive behaviors, and effectively reduce the incidence of lymphedema.

摘要： 目的　探讨基于智慧医疗系统的管理模式应用于乳腺癌患者术后预防淋巴水肿中的效果。方法　选取2020年1月至12月无锡市第二人民医院收治的乳腺癌患者112例，按随机数字表法分为观察组和对照组，各56例。112例患者均为女性，对照组患者年龄为（45.37±6.58）岁，实施常规管理模式；观察组患者年龄为（45.52±6.43）岁，实施基于智慧医疗系统的管理模式。比较两组淋巴水肿知识知晓率、淋巴水肿预防行为以及淋巴水肿发生率。计数资料组间比较采用χ²检验，计量资料组间比较采用独立样本t检验。结果　观察组干预6个月后淋巴水肿知识中发病原因知晓率、临床表现知晓率、治疗方式知晓率、危险因素知晓率与预防方式知晓率分别为83.93%（47/56）、89.29%（50/56）、92.86%（52/56）、83.93%（47/56）、87.50%（49/56），均明显高于对照组的66.07%（37/56）、69.64%（39/56）、76.79%（43/56）、67.86%（38/56）、69.64%（39/56），两组比较差异均有统计学意义（均P<0.05）。观察组干预后6个月淋巴水肿预防行为的皮肤护理、生活方式、避免上肢压迫、避免极端温度评分均高于对照组（均P<0.001）；预防行为总评分为（61.99±3.28）分，高于对照组的（50.44±4.20）分，差异有统计学意义（t=16.219，P<0.001）；观察组干预后6个月淋巴水肿发生率为8.93%（5/56），低于对照组的23.21%（13/56），差异有统计学意义（χ²=4.236，P=0.040）。结论　基于智慧医疗系统的管理模式应用于乳腺癌术后患者中，可显著提高其淋巴水肿认知水平，改善其预防行为，并有效降低淋巴水肿发生率。
