Sepsis is associated with a 36% mortality rate, rising to 50% for septic shock. Currently, when an East Midlands Ambulance Service clinician recognises 'red flag' sepsis, only the oxygen and fluid elements of the 'Sepsis Six' care bundle are delivered, omitting the antibiotic therapy. For a patient in septic shock, every hour's delay in antibiotic therapy is associated with a 7.6% increase in mortality. Ambulance clinicians are therefore appropriately placed to assess and commence treatment at the earliest point of recognition. The aim of this evaluation was to assess the feasibility of training paramedics to recognise 'red flag' sepsis, obtain blood cultures and administer a broad spectrum antibiotic, meropenem, to patients in the pre-hospital environment.
A prospective six-month feasibility pilot evaluation was conducted in May 2016. Paramedics were trained and given access to a broad spectrum antibiotic, meropenem, along with a patient group direction to administer the antibiotic to 'red flag' sepsis patients. Training included sepsis recognition, taking of blood cultures and patient group direction compliance.
Twenty paramedics volunteered and successfully completed the training. Of the 113 patients that were identified as 'red flag' sepsis, 107 (94.6%) were confirmed as infected by the receiving hospital. Ninety-eight blood samples were successfully drawn by study paramedics, with only seven (7.1%) reported as contaminated samples, compared with 8.5% of samples taken by staff in the receiving ED during the same time period. Ninety patients (80%) assessed by paramedics as meeting the criteria were treated with meropenem, and patient group direction compliance was 100%.
Paramedics can safely deliver pre-hospital antibiotics to patients with 'red flag' sepsis and obtain blood cultures prior to administration, with a contamination rate comparable with local hospitals, following a short training course.
脓毒症的死亡率为36%,感染性休克患者的死亡率则升至50%。目前,东米德兰兹郡救护服务机构的临床医生识别出“红旗”脓毒症时,仅执行“脓毒症六步法”护理方案中的给氧和补液措施,而省略了抗生素治疗。对于感染性休克患者,抗生素治疗每延迟一小时,死亡率就会增加7.6%。因此,救护人员在识别出脓毒症的最早阶段就进行评估并开始治疗是合理的。本评估的目的是评估培训护理人员识别“红旗”脓毒症、采集血培养样本并在院前环境中给患者使用广谱抗生素美罗培南的可行性。
2016年5月进行了一项为期六个月的前瞻性可行性试点评估。对护理人员进行培训,并提供广谱抗生素美罗培南,同时给予患者群体指导方针,以便向“红旗”脓毒症患者使用该抗生素。培训内容包括脓毒症识别、采集血培养样本以及患者群体指导方针的依从性。
20名护理人员自愿参加并成功完成培训。在113名被识别为“红旗”脓毒症的患者中,107名(94.6%)被接收医院确诊感染。研究中的护理人员成功采集了98份血样,其中只有7份(7.1%)报告为污染样本,而同期接收急诊科工作人员采集的样本污染率为8.5%。护理人员评估符合标准的90名患者(80%)接受了美罗培南治疗,患者群体指导方针的依从率为100%。
经过短期培训课程后,护理人员能够安全地为“红旗”脓毒症患者提供院前抗生素治疗,并在给药前采集血培养样本,污染率与当地医院相当。
