IV dislodgement data
Many clinical studies on peripheral IVs and central line IVs exist, but most of the studies focus on securement methods, blood infections, and how often IVs should be replaced. Dislodgement, to date, has not been the focus of these papers, but the prevalence of IV dislodgement is identified as being between 3.3 and 36%. Since IV dislodgement is not the focus of these papers, patients that are agitated or mentally impaired are often excluded from the studies. These are the very patients that are most likely to dislodge their IVs. We believe the rate of IV dislodgement in clinical studies is artificially low due to the exclusion criteria that is commonly adopted.
The clinical studies that list dislodgement rates focus on varying issues such as pediatric patients, oncology patients, emergency room patients as well as different types of IV lines such as peripheral and PICC lines.
The hospitals range from children's hospitals, general hospitals, level 1 trauma centers to skilled nursing facilities. The papers are from all over the world: USA, Australia, UK, Spain, and others, which shows us that dislodgement is a global issue. The chart to the right shows clinical paper information for only peripheral IVs. The overall dislodgement rate average is 10.8% for all of the studies.
Peripherally Inserted Central Catheters (PICC) are more expensive to install and more complicated than a traditional peripheral IV. Clinical studies on PICC lines have a very similar dislodgement rate to peripheral IVs. The dislodgement rate average from the six studies to the right is 7.3%.
Central Venous Catheters (CVC) or Central Lines are the most expensive vascular access devices to install. They are frequently used to deliver chemotherapy drugs and often require the patient to be anesthetized during insertion of the device.
There are very few clinical studies on CVCs that report dislodgement rates. The average from the two studies to the right is 6.3%. One study focuses on oncology patients receiving chemotherapy drugs while the second study focuses on patients in an Intensive Care Unit. These are two very different patient populations with treatment occurring in very different departments of the hospital. As one might expect, the dislodgement rates are very different as well.
We are not aware of an existing study that discusses the overall cost of IV dislodgement, which would include: cost to clean-up a patient's room, the cost of replacement medicine, the cost of additional IV access kits, the cost of delayed medical treatment and the cost of the medical professional reinserting the IV. Lineus Medical is undertaking a study to establish a benchmark on the rate at which IV dislodgement occurs in all patients and the overall cost of IV dislodgement.
a solution to the dislodgement problem
When a harmful force goes across the IV line, rather than trying to hang onto an IV line, let's create a controlled separation. The IV can be saved, the patient avoids a restick, the nurse can do value added work, the hospital saves money and everyone saves the stress, time and expense involved with an IV restart. The video introduces SafeBreak Vascular, a Patient Safety Disconnect, which is designed to remove harmful mechanical forces from the IV line and catheter.
