Objectives:
To evaluate whether antibiotic prescribing and pathways for suspected neutropenic fever (sNF) in adults attending hospital are safely reduced through implementing a multifaceted antibiotic stewardship intervention (ASTERIC).
Hypothesis:
In ED and hospitalised patients with sNF, the ASTERIC protocol effectively and safely reduces the use of ultra-broad spectrum antibiotics (UBSAs) compared with SoC alone.
Design:
pragmatic, parallel, multi-centre, type 1, hybrid effectiveness-implementation, stepped-wedge, before and after, cluster randomised controlled trial with variable baseline and follow up periods.
Setting:
Eight hospitals in Hong Kong.
Participants:
416 patients (208 patients in each group) adult patients with sNF ≥38.3ºC and Modified Early Warning Score ≤6 within 24 hours of ED registration.
Interventions:
Healthcare professionals receive a multifaceted stewardship intervention consisting of risk assessment tools, fast track absolute neutrophil counts (ANCs), a decision tool for patient management and antibiotic use supported by an educational package and staff interaction programmes (ASTERIC protocol).
Instruments:
ANC, cancer therapy and chronic illness therapy scores; Proctor conceptual framework for implementation research outcomes incorporating RE-AIM.
Main outcome measures:
mean total dose of UBSAs prescribed in 7 days and SAEs at 30 days.
Data analysis:
ITT, PP and AT analyses for service outcomes (effectiveness, safety, quality
of life assessments and cost-effectiveness analysis; mixed methods for implementation, informed by the Theoretical Domains Framework (TDF)).
Expected results:
Study results will inform health policy with improvement in hospital services in treating stable sNF evidenced by improved safe antibiotic stewardship, early antibiotic de-escalation, and reduced costs and length of stay

關於此研究
目標:
評估通過實施多層面的抗生素管理干預措施(ASTERIC)是否能安全地減少在入院的成人疑似嗜中性白血球減少發燒 (sNF)患者的抗生素處方量及治療路徑。
假設:
在急症室就診和住院的 sNF 患者中,與僅使用常規護理 (SoC)相比,ASTERIC 協議能有效且安全地減少超廣譜抗生素 (UBSAs)的使用。
設計:
務實的、平行的、多中心、有效性-實施混合一型、階梯楔形、前後對照、集群隨機控制試驗,設有可變基線和隨訪期。
地點:
香港八間醫院。
參與者:
416 名成人患者(每組 208 名),sNF 患者體溫 ≥38.3ºC,並於急症室登記後 24 小時內的修訂早期預警分數 (MEWS)≤6。
干預措施:
醫療專業人員將接受多層面的干預措施,包括風險評估工具、快速處理的絕對中性粒細胞計數(ANC)、患者管理和抗生素使用的決策工具,以及教育套件和員工互動方案(ASTERIC 協議)。
工具:
包括 ANC、癌症治療和慢性病治療評分;使用 Proctor 概念框架和 RE-AIM 框架評估實施研究成果。
主要結果衡量:
7 天內處方的 UBSAs 總劑量平均值以及 30 天內的嚴重不良事件 (SAEs)。
數據分析:
使用 ITT(意向治療分析)、PP(按方案分析)和 AT(實際治療分析)來評估服務結果(效能、安全性、生活質量評估和成本效益分析);實施評估將採用混合方法,並根據理論領域框架(TDF)進行。
預期結果:
研究結果將為醫療政策提供依據,通過改善對穩定 sNF 患者的醫院服務來提高安全的抗生素管理,包括抗生素的早期減量、縮短住院時間並降低成本。
