The primary purpose of this study is to evaluate the impact of an Emergency Medical Services (EMS) based sepsis screening and early warning protocol on the timing of early sepsis care in the Emergency Department (ED).
Sepsis is life-threatening medical emergency and a common cause of morbidity and mortality among hospitalized patients. Recognizing and treating sepsis immediately is key to achieving optimal patient outcomes after sepsis. The prehospital, EMS setting represents a unique opportunity to implement best practice by operationalizing guideline-recommended, system-wide sepsis screening protocols in an effort to facilitate earlier recognition of sepsis and minimize delays in evaluation and treatment. Unfortunately, evidence-based screening tools to assist EMS providers in recognizing this heterogenous syndrome are lacking, and recognition by EMS providers is generally poor.
The purpose of this study is to evaluate the prehospital sepsis (PRESS) protocol, which is an evidence-based sepsis screening and early communication protocol designed for use in the prehospital, EMS environment. The PRESS protocol pairs a validated sepsis screening tool with a prehospital sepsis alert to the receiving ED for patients who are screen positive. This innovative approach has been used to improve patient care and outcomes in other life-threatening, time-sensitive medical emergencies including heart attack and stroke. Prehospital screening and an early warning call to the ED before patient arrival provides valuable lead time that makes immediate evaluation and treatment by EMS providers possible once a patient arrives in the ED.
This study includes three study sites which are each comprised of cluster pairs of one EMS organization and one partnered acute care hospital. Each cluster pair will participate in both a baseline and intervention phase of study. EMS providers will be trained to screen for sepsis according to the PRESS protocol. The PRESS EMS protocol includes 2 major components: 1) an evidence-based sepsis screening tool, and 2) a prehospital sepsis alert call to the receiving hospital for participants who screen positive. Upon arrival to the ED, ED providers will provide immediate medical assessment to the patient to determine whether there is concern for sepsis. The overarching hypothesis is that implementation of an EMS-based sepsis screening and early warning protocol will be associated with a reduction in time first antibiotic administration in the ED among patients with sepsis.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| PRESS Intervention | Experimental | Study sites will participate in the intervention phase for 6 to 18 months, depending on the order of cluster randomization. Sites will switch from the baseline phase in approximately 6 month blocks, with all sites delivering the intervention for the final 6 months of the study. |
|
| Standard of Care | No Intervention | Study sites will participate in the standard of care phase to collect baseline data for 6 to 18 months, depending on the order of cluster randomization. All sites are in the baseline phase for the first 6 months then sites will switch one at a time, every 6 months, to the intervention phase of the study. |

| PRESS Intervention | Behavioral | The study intervention is PRESS protocol training and educational delivered to EMS providers, followed by protocol implementation. EMS providers will be trained to screen all EMS patients for protocol eligibility and will start using the protocol at the beginning of the intervention phase. The PRESS EMS protocol includes 2 major components: 1) an evidence-based sepsis screening tool, and 2) a prehospital sepsis alert call to the receiving hospital for participants who screen positive. Upon arrival to the ED, ED providers will provide immediate medical assessment to the patient to determine whether there is concern for sepsis. If the treating provider determines there is concern for sepsis, the provider will deliver usual sepsis care per local hospital protocols, workflows, or care pathways. Sepsis treatment interventions will not be specified by this study protocol. |
| Measure | Description | Time Frame |

| Time to First Antibiotic Administration in the ED | Among eligible EMS patients with sepsis, the time from ED arrival to first antibiotic administration (parenteral only) in the ED will be examined. Time will be censored at the time of hospital admission or ED discharge. | During ED stay on Day 1 |
| Measure | Description | Time Frame |

| EMS Documentation of Sepsis | Among eligible EMS patients with sepsis, the proportion with EMS documentation of suspected or possible sepsis or positive PRESS screen will be assessed. | During ED stay on Day 1 |

A limited, de-identified, participant-level dataset will be shared. This dataset will include participant demographics, EMS physiologic data, as well as sepsis screening, classification, and outcomes data.
Data will become available starting after publication of the primary study manuscript (anticipated start date July 2025) and will be available through the Emory Dataverse indefinitely.
A limited data set will be available to the general public for the purposes of conducting analyses such as a secondary analysis or meta analysis. Data can be accessed through the Emory Dataverse after requesting access from the primary study investigator.

This is a multicenter, cluster-randomized, stepped-wedge implementation study of an EMS sepsis screening and early communication protocol. Each study cluster represents one EMS organization and one partnered acute care hospital. Each cluster pair will participate in both a baseline and intervention phase of study varying between 6-18 months each (baseline and intervention), in approximately 6 month blocks, depending on the order of cluster randomization.

Among eligible EMS patients with sepsis, the proportion who receive sepsis bundle care within 3 hours of ED arrival (sepsis bundle = blood culture order, lactic acid order, antibiotic administration) will be assessed. Care bundle elements will be analyzed individually and in composite. |
| During ED stay on Day 1 |
| Time to Sepsis Bundle from ED Arrival | Among eligible EMS patients with sepsis, the time to sepsis bundle care elements from ED arrival will be assessed. Time will be censored at the time of hospital admission or ED discharge. | During ED stay on Day 1 |
| Time to First Care Provider Documentation | Among all eligible EMS patients, the time from ED arrival to first care provider documentation in the ED will be assessed. | During ED stay on Day 1 |
| Proportion of Patients Without Sepsis Receiving Antibiotics in the ED | Among all eligible EMS patients without sepsis, the proportion who receive antibiotic administration (parenteral only) in the ED will be assessed. | During ED stay on Day 1 |
| Antibiotic Days of Therapy | The total number of antibiotic days of therapy (DOT) will be assessed. Antibiotic DOT is measured as last calendar day of consecutive antibiotic therapy minus the first calendar day of antibiotic therapy, among patients with and without sepsis. | Up to 10 days (on average) |
| Proportion of Patients Admitted to the ICU | Among all eligible EMS patients with and without sepsis, the proportion admitted from the ED directly to ICU level of care will be assessed, stratified by sepsis status. | During hospital stay (up to 20 days, on average) |
| Hospital Length of Stay | Among all eligible EMS patients with and without sepsis, total hospital length of stay will be assessed, stratified by sepsis status. Hospital length of stay is defined as days since ED arrival to day of hospital discharge. | During hospital stay (up to 20 days, on average) |
| In-hospital Death | In-hospital death among patients with and without sepsis will be assessed, stratified by sepsis status. | During hospital stay (up to 20 days, on average) |
