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。
