Evaluation of the Implementation of a Novel Fluid Resuscitation Device in the Prehospital Care of Sepsis Patients: Application of the Implementation Outcomes Framework.

Objectives: Early identification and fluid resuscitation are recognized performance measures within sepsis care. Despite fluid resuscitation, fluid goals are often not achieved in the prehospital environment. Furthermore, description of implementation process and evaluation of implementation success are historically underreported in prehospital research. The objective of this study was to contextualize and evaluate the system-wide implementation of a novel fluid resuscitation device, the LifeFlow PLUS^®, in the treatment of prehospital sepsis patients.

Methods: A single urban emergency medical services (EMS) system internally decided to adopt a novel fluid resuscitation device. This EMS system added the device to the clinical care guidelines of suspected sepsis patients. Prior to and during implementation of the new guidelines, several strategies were undertaken to promote consistent, appropriate system-wide use of the device. A mixed methods study design was deployed. Surveys of EMS clinicians and leaders assessed perceptions of the device and sepsis education prior to field implementation of the device. Clinician and leader semi-structured interviews assessed implementation experience and device adoption. Document analysis evaluated deployment of implementation strategies. Data were triangulated to contextualize implementation and evaluate success.

Results: Clinician (88%) and leader (91%) confidence in appropriate clinician device use and device superiority for sepsis care (73 and 100%, respectively) were high. Clinicians (58%) were less likely to view the device as easy to implement compared to leaders (73%). Three themes were developed from semi-structured interviews, including "exposure" to the device, "reinforcing factors" to prompt device use, and "clinician buy-in." Twenty unique implementation strategies (e.g., dynamic trainings, mandating change) were used to promote successful system-wide device adoption.

Conclusions: The overall implementation success of this novel fluid resuscitation device was moderate. Barriers to adoption included complexity of clinical decision-making and ease of device use. Facilitators to adoption included the use of multiple modes of education, clinical reminders, presenting evidence of device benefit, and prehospital culture. Prior to future prehospital implementation programs, EMS systems should focus on identifying and addressing key barriers and facilitators to improve adoption.
