For diabetic patients, nurses must obtain a blood sample a minimum of four times a day. When an insulin IV drip is utilized, blood glucose will typically be monitored hourly until it is stable, and usually every two hours after stabilization.(1,2) Even if the patient already has an IV established, each blood sample requires a new stick. It is common for patients to compare their time in the hospital to a role of being a pincushion that gets repeatedly stuck over and over again.
The graphic to the upper right shows the costs and pain points associated with a diabetic patient in the hospital for five days and receiving five blood draws per day. With a traditional peripheral IV, a patient will have 25 needle sticks just for blood draws over five days.(3)
Another issue for patients is the basic fear of needles. A large study with 3315 patients was conducted at the Mayo Clinic and published in 2006 that assessed the fear of needles. 15% of study participants reported feeling afraid during injections. 7.5% described their fear as excessive and 2.2% of the patients were assessed as having a specific phobia of needles.(4) If 15% of the population is afraid of an injection, then something should be done to limit the number of sticks an individual will receive.
The goal should be that once venous access is established that all medication and all blood draws that are needed can be accomplished through the established IV line. Since we have venous access, shouldn't we be able to get a blood draw without sticking the patient over and over again? The BVAD provides a solution.
The BVAD is being designed to allow uncontaminated blood draws while simultaneously maintaining an IV infusion. If a nurse knows that a patient will require regular blood draws, they can install a dual-lumen BVAD rather than a traditional, single lumen catheter. The video to the right is a lab simulation that shows how BVAD can allow the transfusion of medication through one catheter and through a second catheter, take an uncontaminated blood draw.
