Glucometer to use on multiple patients - page 3

by CrunchRN

Hi All, I need to get a glucometer to use in a research study on multiple participants. I have 2 questions: 1. What glucometer do you like? 2. what single use disposable lancets do you like? Your help is very much... Read More

    So, I'm a former biochemist now nursing student (long story, naturally) and what I've seen with the CBG readers (as CNA in the hospital) is that they have a pretty big error margin, sometime 30 points or more difference on different hands or comparing before someone washed their hands and after. If it's something you'll have to graph or find a stdev on, you may want to take a few reading from a single poke with a longer lancet. The hopital I'm at school at uses single use lancets with a purple cap and an adjustable lancet; I'm sorry I don't know the brand. Good luck!

    This is probably moot since you've already gotten hold of the supplies, but doing a blood glucose on someone tells you very little about their overall diabetic/non-diabetic status. You can get a reading of 60 on someone who will register 260 after a meal.

    For more dependable information I would do hA1c tests on subjects. That would give you a much more accurate result.

    Very good points. However, since this is a pilot study we are going to have to go with the easiest screening approach. If we end up expanding the study after the pilot i will definitely suggest the A1C route.

    But.... if you really want to be sure you've excluded diabetics, and you don't really exclude them, your pilot results may be unreliable, and then what? Want to defend that to your committee? ::shudder::

    Do the A1c.

    Sarcasm?
    Actually, that is the policy at my facility too: we use prepackaged disinfectant wipes after each patient.

    Granted, I'm not in LTC doing 10-20 readings a shift...so your mileage may vary.

    No committee for me. This is full professor driven and they feel is it close enough for the purpose of this pilot. With pilot studies you have a lot more lattitude. Then when the evaluation happens and if is decided to go ahead that is when things will get very stringent. No way are they going to cover the cost of A1c's along with everything else for a 20 subject pilot. Diabetes in and of itself is not an issue. Just they want "generally healthy".

    if you can "stick" them within an hour of eating, you may get a "truer" picture.....It has been known for years that a fasting is no longer the gold standard. Good luck.

    Understood, unfortunately they need to be fasting. However, if it becomes a full study they will be brought in for a non-fasting screening only appt.

    In an ideal fully funded world....................

    No, you and I are in long term care, where this is standard. I don't think Crunch is.....
    I think we must use a different kind of glucometer. Like GrnTea said, with the standard kind that uses a different disposable test strip for each use, I don't see where there's a risk for cross contamination.

    That's the type we use (Accu-chek with the single-use test strip, used with the single-use disposable lancet), yet they still make us scrub the machine down between each stick. I'm inclined to agree with you though--unless the patient's blood gets loose on the equipment, there should be minimal risk of cross-contamination.
