Brief summary

The purpose of this study is to determine if there is one method of identifying the proximal humerus intraosseous vascular access site that is easier for clinicians to use, out of the 4 methods being evaluated.

Detailed description

This was a non-controlled study using licensed/certified EMT/paramedics and licensed nurses as device operator subjects identifying the proximal humerus IO insertion site and inserting the IO catheter in healthy adult volunteers. Forty (40) clinicians with no prior training on establishing IO vascular access in the proximal humerus IO insertion site were enrolled in the study as device operator subjects. Twenty (20) healthy adult volunteers were enrolled in the study to have IO vascular access established bilaterally in the proximal humerus with one device operator accessing one of the subject's arms, according to their assigned method for identifying the proximal humerus intraosseous vascular access site.

Design outcomes

Primary

MeasureTime frameDescription
Ease of Use ScoreWithin 10 minutes of procedureDevice operators will score their perceived Ease of Use for their assigned Intraosseous Insertion method for their one unilateral proximal humerus IO site procedure. The Ease of Use scale scores range from 0 to 10, where 0=extremely difficult and 10=extremely easy. Higher scores indicate greater ease of use.
Level of Confidence Scorewithin 10 minutes of procedureDevice operators scored their perceived Level of Confidence with their assigned Intraosseous Insertion method for their one unilateral proximal humerus IO site procedure. The Level of Confidence scale scores range from 0 to 10, where. 0=no confidence and 10=extremely confident. Higher scores indicate greater level of confidence.
Proximal Humerus Intraosseous (IO) Insertion Site Placement Scorewithin 10 minutes of the procedureThe ability of the device operator to insert the Intraosseous device into the "ideal target area" was scored using an accuracy scoring scale. The "ideal target area" was defined as the center of the greater tubercle. The following scoring scale ranging from 0 to 3 was used. 3= center of the greater tubercle; 2=sightly off-center of the greater tubercle, 1=borderline of the greater tubercle, and 0=completely outside the greater tubercle. Higher scores indicate better insertion position.
Time to Intraosseous (IO) Catheter Placementwithin 10 minutes of the procedureThe amount of time it takes for the device operator to identify the proximal humerus intraosseous (IO) insertion site using their assigned proximal humerus IO site identification method and insert the IO needle Timing starts from the time the participant begins to palpate the proximal humerus and stops when the IO needle is inserted.

Recruitment details

40 licensed/certified clinicians with no prior training on establishing intraosseous (IO) vascular access in the proximal humerus (PH) were recruited for participation as device operators to learn one PH IO site identification method and perform one unilateral proximal humerus IO site insertion procedure. 20 healthy adults were recruited to receive PH IO vascular access in each PH using a different PH IO site identification method for each.

Pre-assignment details

Healthy volunteers had a physical exam to confirm no excess tissue was overlaying the proximal humerus IO insertion site and adequate landmarks were visible. Clinicians were trained on and had to correctly demonstrate their assigned method for IO vascular access in the proximal humerus for approval to participate as a device operator.
