[目的]研究血液病化疗患者医院内感染高危人群的筛查方法并观察护理干预效果.[方法]回顾性分析1 624例血液病化疗患者的临床资料,观察医院内感染各危险因素,确定血液病化疗患者医院内感染高危人群筛查的判别阈值.应用判别阈值对血液病化疗患者进行筛查,并对医院内感染高危人群进行护理干预.[结果]以累计分值57为判别阈值时约登指数最大,灵敏度为95.7%,特异度为58.2%;干预组医院内感染发生率较对照组显著下降(分别为34.66%和48.12%,χ2=17.632,P=0.000).[结论]血液病化疗患者医院内感染高危人群的筛查和护理干预可降低血液病化疗患者医院内感染的发生率.
[Objective] To study the screening methods of high-risk patients with nosocomial infection in hematological diseases and observe the effect of nursing intervention. [Methods] The clinical data of 1 624 patients with hematological diseases and chemotherapy were retrospectively analyzed. The risk factors of nosocomial infection were observed, The screening threshold of patients with high-risk inpatients with chemotherapy in patients with chemotherapy and chemotherapy was screened.Different thresholds were used to screen patients with chemotherapy of hematopathy and nursing intervention in high-risk patients in hospital.Results When the cumulative score 57 was used as the discrimination threshold The index of indention was the largest, with a sensitivity of 95.7% and a specificity of 58.2%. The incidence of nosocomial infections in the intervention group was significantly lower than that of the control group (34.66% and 48.12%, respectively, χ2 = 17.632, P = 0.000) Screening and nursing interventions at high risk in patients with nosocomial infections in chemotherapy patients may reduce the incidence of nosocomial infections in patients with hematologic malignancies.
