Timely recognition of sepsis in emergency department (ED) is challenging. We evaluated the impact of implementing the biomarker monocyte distribution width (MDW) at bedside, on the time to anti-infective administration. We conducted a before-and-after cohort study in the ED of an academic hospital in Paris, to compare sepsis patients care and outcomes, before and after the implementation of point of care (POC) MDW measurement in the ED. During post-implementation period (period-2), MDW was measured with complete blood count by ED nurses with results given in 2 min: if above 21.5 units, ED physicians were asked to consider sepsis and to start an anti-infectious as soon as possible. Primary endpoint was time to anti-infectious administration (TTA) from ED arrival, and secondary endpoints were TTA from sepsis onset (TTAS), length of stay, mortality, and hospitalization rates. In total, 255 patients (period-1) and 180 patients (period-2) with sepsis were included. The TTA was 5.4 h (3.5–7.7) period-1 and 4.9 h (IQR 2.5–7.1) in period-2 (p = 0.06). MDW implementation significantly reduced the median TTAS from to 3.7 h (IQR 1.5–5.8) in period-1, to 2.2 h (IQR 0.5–4.5) in period-2 (p < 0.001). Mortality rates remained similar between the two periods (18% vs. 16% respectively, p = 0.4), as did hospitalization rates (93% vs. 91%, p = 0.4) and ED length of stay (7.2 h (5.3–9.8) vs 7.0 (5.4–9.4), p = 0.7). Implementing POC MDW measurement in the ED protocols enhances the timeliness of anti-infective administration from sepsis onset, meeting current sepsis management guidelines.

急诊科脓毒症患者实施单核细胞分布宽度 (MDW) 测量对抗感染给药时间的临床影响:一项前/后队列研究



在急诊科 (ED) 及时识别脓毒症具有挑战性。我们评估了在床边实施生物标志物单核细胞分布宽度 (MDW) 对抗感染给药时间的影响。我们在巴黎一家学术医院的急诊科进行了一项前后队列研究,以比较在急诊科实施床旁 (POC) MDW 测量前后脓毒症患者的护理和结果。在实施后期间(第 2 期),急诊科护士用全血细胞计数测量 MDW,并在 2 分钟内给出结果:如果高于 21.5 个单位,则要求 ED 医生考虑败血症并尽快开始抗感染治疗。主要终点是到达急诊科后抗感染给药 (TTA) 的时间,次要终点是脓毒症发作后 TTA (TTAS) 、住院时间、死亡率和住院率。总共纳入 255 例脓毒症患者 (第 1 期) 和 180 例 (第 2 期) 患者。第 1 期的 TTA 为 5.4 小时 (3.5-7.7),第 2 期为 4.9 小时 (IQR 2.5-7.1) (p = 0.06)。MDW 的实施显着降低了中位 TTAS 从第 1 期的 3.7 小时 (IQR 1.5-5.8) 到第 2 期的 2.2 小时 (IQR 0.5-4.5) (p < 0.001)。两个时期之间的死亡率保持相似 (分别为 18% vs. 16%,p = 0.4),住院率 (93% vs. 91%,p = 0.4) 和 ED 住院时间 (7.2 小时 (5.3-9.8) vs 7.0 (5.4-9.4),p = 0.7)。在 ED 方案中实施 POC MDW 测量可增强从脓毒症发作开始抗感染给药的及时性,符合当前的脓毒症管理指南。
