Fever and neutropenia (FN) is a common complication of pediatric oncology therapy and accounts for a large number of hospital admissions. Standard therapy for FN includes hospital admission and empiric antibiotics. Strict adherence to this practice leads to prolonged hospitalizations that may be unnecessary for patients at low risk of having an underlying significant infection.
Children admitted with FN could be discharged after a minimum of 48 hr with no further antibiotic therapy once they had been afebrile for 24 hr with negative blood cultures from initial presentation, regardless of their neutrophil count. We performed a retrospective review with regard to readmissions and subsequent documented infections in FN patients discharged with an ANC of ≤500 cells/mm(3) .
There were 299 FN admissions in 188 patients who were discharged prior to achieving an ANC of ≥500 cells/mm(3) . Readmission to the hospital during the same period of neutropenia occurred in 50 cases (16.7%) with 27 infections diagnosed in 21 patients. Patients discharged with an ANC of ≤100 cells/mm(3) (odds ratio 3.7) and patients with acute lymphoblastic leukemia (odds ratio 2.6) were more likely to be readmitted for fever. All patients that developed a significant infection had an ANC of ≤100 cells/mm(3) at admission and discharge. In patients that developed a significant infection, only one required admission to the intensive care unit with no deaths.
The practice of discharging patients with persistent neutropenia who are afebrile with negative blood cultures produces acceptable rates of readmission and subsequent infection and does not lead to increased morbidity and mortality.
发热伴中性粒细胞减少症(FN)是儿科肿瘤治疗常见的并发症,导致大量患儿住院。FN的标准治疗包括住院及经验性使用抗生素。严格遵循这一治疗方式会导致住院时间延长,而对于潜在严重感染低风险的患者而言,这种延长可能是不必要的。
因FN入院的儿童,若自首次就诊起体温正常24小时且血培养阴性,无论其中性粒细胞计数如何,最少住院48小时后可不再接受进一步抗生素治疗而出院。我们对ANC≤500个细胞/mm³出院的FN患者的再次入院情况及随后记录的感染情况进行了回顾性分析。
188例患者中有299次FN入院,这些患者在ANC≥500个细胞/mm³之前就已出院。在同一中性粒细胞减少期内,50例(16.7%)患者再次入院,21例患者被诊断出27次感染。ANC≤100个细胞/mm³出院的患者(比值比3.7)及急性淋巴细胞白血病患者(比值比2.6)因发热再次入院的可能性更高。所有发生严重感染的患者入院及出院时ANC均≤100个细胞/mm³。发生严重感染的患者中,只有1例需要入住重症监护病房,无死亡病例。
对于血培养阴性且体温正常的持续性中性粒细胞减少症患者予以出院的做法,再次入院率及随后的感染率均可接受,且不会导致发病率和死亡率增加。
