Prehospital Tourniquets in Civilians: A Systematic Review.

ABSTRACT:

Objectives

Terrorist attacks and civilian mass-casualty events are frequent, and some countries have implemented tourniquet use for uncontrollable extremity bleeding in civilian settings. The aim of this study was to summarize current knowledge on the use of prehospital tourniquets to assess whether their use increases the survival rate in civilian patients with life-threatening hemorrhages from the extremities.

Design

Systematic literature review in Medline (Ovid), Embase (Ovid), Cochrane Library, and Epistemonikos was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. The search was performed in January 2019.

Setting

All types of studies that examined use of tourniquets in a prehospital setting published after January 1, 2000 were included.

Primary/secondary outcomes

The primary outcome was mortality with and without tourniquet, while adverse effects of tourniquet use were secondary outcomes.

Results

Among 3,460 screened records, 55 studies were identified as relevant. The studies were highly heterogeneous with low quality of evidence. Most studies reported increased survival in the tourniquet group, but few had relevant comparators, and the survival benefit was difficult to estimate. Most studies reported a reduced need for blood transfusion, with few and mainly transient adverse effects from tourniquet use.

Conclusion

Despite relatively low evidence, the studies consistently suggested that the use of commercial tourniquets in a civilian setting to control life-threatening extremity hemorrhage seemed to be associated with improved survival, reduced need for blood transfusion, and few and transient adverse effects.

Project description:BackgroundTelemedicine offers a unique opportunity to improve coordination and administration for urgent patient care remotely. In an emergency setting, it has been used to support first responders by providing telephone or video consultation with specialists at hospitals and through the exchange of prehospital patient information. This technological solution is evolving rapidly, yet there is a concern that it is being implemented without a demonstrated clinical need and effectiveness as well as without a thorough economic evaluation.ObjectiveOur objective is to systematically review whether the clinical outcomes achieved, as reported in the literature, favor telemedicine decision support for medical interventions during prehospital care.MethodsThis systematic review included peer-reviewed journal articles. Searches of 7 databases and relevant reviews were conducted. Eligibility criteria consisted of studies that covered telemedicine as data- and information-sharing and two-way teleconsultation platforms, with the objective of supporting medical decisions (eg, diagnosis, treatment, and receiving hospital decision) in a prehospital emergency setting. Simulation studies and studies that included pediatric populations were excluded. The procedures in this review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. The Risk Of Bias In Non-randomised Studies-of Interventions (ROBINS-I) tool was used for the assessment of risk of bias. The results were synthesized based on predefined aspects of medical decisions that are made in a prehospital setting, which include diagnostic decision support, receiving facility decisions, and medical directions for treatment. All data extractions were done by at least two reviewers independently.ResultsOut of 42 full-text reviews, 7 were found eligible. Diagnostic support and medical direction and decision for treatments were often reported. A key finding of this review was the high agreement between prehospital diagnoses via telemedicine and final in-hospital diagnoses, as supported by quantitative evidence. However, a majority of the articles described the clinical value of having access to remote experts without robust quantitative data. Most telemedicine solutions were evaluated within a feasibility or short-term preliminary study. In general, the results were positive for telemedicine use; however, biases, due to preintervention confounding factors and a lack of documentation on quality assurance and protocol for telemedicine activation, make it difficult to determine the direct effect on patient outcomes.ConclusionsThe information-sharing capacity of telemedicine enables access to remote experts to support medical decision making on scene or in prolonged field care. The influence of human and technology factors on patient care is poorly understood and documented.

Project description:BackgroundTourniquets used for peripheral venous vascular access such as blood sampling are regularly contaminated in clinical routine. Although most contaminations are harmless, some pose a possible risk for infection. To improve peripheral venous access infection control standards, tourniquets with no or as few as possible bacterial burden should be used. Conventional tourniquets can be reprocessed by autoclaving or by incubating in disinfectants. However, both methods are time-consuming and not suitable for immediate use between patients. In contrast, silicone tourniquets can be quickly and simply reprocessed with wipe disinfection. In vitro studies from the manufacturer have demonstrated reduced bacterial contamination on silicone tourniquets after usage compared to conventional tourniquets. This study aims to independently investigate the bacterial load on both types of tourniquets in clinical routine.MethodsIn a first trial, new conventional and silicon tourniquets were used for blood sampling in one facility with strict guidelines for reprocessing (after each patient or not at all) for 1 day and tested for bacterial contamination. In a second trial, new tourniquets were used in four facilities while the mode and frequency of tourniquets' reprocessing was defined individually by each facility. The number of treated patients, mode and frequency of reprocessing and other relevant handling measures were documented.ResultsUnder controlled conditions, with strictly specified reprocessing, slightly fewer bacteria were found on silicone than on conventional tourniquets. In routine clinical practice the reprocessing frequency was not higher for silicone tourniquets in practice. Yet, in all four facilities, there were significantly fewer bacteria found on silicone than on conventional tourniquets.ConclusionAlthough tourniquets are classified as non-critical medical devices, results show - together with benefits of faster and easier reprocessing - that silicone tourniquets can improve infection control of venous vascular access.
