Situation overview
The post anesthesia care unit (PACU) at our acute care facility consists of two separate departments under the same management. The combined bed capacity of 20 can be expanded to include 6 more overflow beds when patient saturation is high. Maximum saturation occurs when there are no in house available beds, which means the PACU patients convert to “floor care”, and will remain in our unit until a regular hospital bed becomes available. Our patient population is 95% adult, including geriatrics, the 5% being pediatric outpatient procedures of ages 1 month to 16 years. (Above 16 is considered adult.) We recover patients following various surgery procedures from appendectomies to craniotomies, radiological intervention procedures, and any procedure requiring conscious sedation or general anesthesia. The only surgery clientele we do give post operative care to are the cardiac surgery patients.
A significant number of our clients on any given day are diabetics, so finger sticks for accuchecks to measure glucose levels are frequently done in the PACU. When an anesthesiologist deems one to be needed during a surgical procedure, a PACU nurse will be called into the OR suite to perform the test. While this is only a 5 minute task in all, it can often occur when the PACU nurse is already caring for her own fresh post operative patients who are still emerging from anesthesia.
Task
The task our PACU hopes to accomplish is to augment finger stick accuchecks with continuous glucose monitoring (CGM) during the perioperative stay on all known and suspected diabetic patients. In addition to accuchecks increasing the nurses’ workload while being uncomfortable to the patient, accuchecks only provide an isolated glimpse of what a patient’s glucose level is. While peritoneal glucose levels are not as accurate as serum blood levels, a constant measurement of trends can be observed every 1 to 15 minutes, depending on the external monitor setting. This affords a great advantage to the patient because glucose swings can be detected before becoming extreme. (medronics 2010).
When a trend towards hyper or hypoglycemia is observed, a finger stick will accurately assess the necessary intervention. Elevated blood sugars will be averted and hypoglycemic episodes will be prevented. If the trends are fairly consistent and within designated parameters, then routine accuchecks only need to be done every 12 hours instead of the traditional four throughout the patient’s hospital stay.
Product Description
Of the 7 FDA approved continuous glucose monitoring devices (CGMD) currently on the U.S. market (George 2009), our PACU has decided to work with three different vendors; Abbot, Medtronics, and DexCom. Abbot offers the Free Style Navigator, Medronics offers the Guardian Heal, and DexCom offers the Seven Plus. All three of these companies are U.S. based with international expansion and all present as solid companies who will be around for years to come (medronics, abbott, dexCom 2010).
California based Abbot Diabetes Care (http://www.abbottdiabetescare.com/) is “devoted to the discovery, development, manufacture and marketing of pharmaceuticals and medical products” to “reduce the discomfort and inconvenience of blood glucose monitoring…”(abbott 2010). Medronics, http://www.medronicdiabetes.com/, a stable company, also California based, was founded in 1949 and incorporated in 1957 is one of the world’s largest vendors for a multitude of different medical products. Their mission statement is to “alleviate pain, restore health and extend life” (medronics). Their continuous glucose monitoring product, the Guardian Heal, is similar to the Seven Plus offered by DexCom with minor variations (Holt 2008).
The president and CEO of DexCom, (www.dexCom.com) founded in 1999, became such after retiring from Medtronics in 2002. From 2003-2004, Mr. Terrance Gregg served as the Chair of the Research Foundation Board of the American Diabetes Association. DexCom focuses 100% on continuous glucose sensing technologies, working toward a future permanent implantable “pancreas” (dexCom 2010).
While all of these devices use the same technology, for the purpose of avoiding redundancy, only the DexCom Seven Plus is portrayed below.
All three companies have a wireless receiver as pictured above, about the size and weight of a cell phone which receives input then portrays it on a screen. The receiver can only be 5 to 10 feet from the patient to transmit (medronics, abbot, and dexCom 2010). This one allows a distance of 5 feet (dexCom 2010).
The enlarged photo of the Seven Plus screen shows the glucose reading of 160, a large arrow indicating a current increase or decrease in sugar levels, and a trend graph which can be manipulated to display 1, 3, 6, 12, and 24-hour glucose trends (dexCom 2010).
The horizontal dotted lines are the alarm settings of high and low glucose ranges which do respond audibly if limits are exceeded. They also provide clear demarcation of any spikes in either direction as they are happening (medronics, abbott, dexCom 2010).
The sensor, the second of three components of CGMD, is a glucose oxidase/based electrochemical sensor placed beneath the skin into the subcutaneous tissue, the feeling of insertion being equivalent to a finger stick (George 2009). It is about the size of two human hairs and is very soft, flexible, and attaches to the skin with an adhesive patch. It is good for up to 7 days in the Seven Plus, 5 in the Medronics Guardian, and only 3 in the Abbott Navigator (medronics, abbot, dexCom 2010).
The adhesive patch attaches the sensor to the transmitter, which sends interstitial glucose levels to the receiver usually every 5 minutes, and is water proof (medronics, abbott, and dexcom 2010).
In addition to the previously mentioned advantages of patient comfort, rapid recognition of abnormal glucose swings, and less nursing time on the task, the greatest advantage to the patient is comparable to the accucheck being like a snapshot whereas the CGMD is like a video, hence much quicker at detecting undesirable glucose levels. And while interstitial glucose levels lag behind serum levels on the average of 7 minutes, recent studies show that when glucose levels are falling, the interstitial glucose fluid may drop faster than the serum level, which would further prevent an acute hypoglycemic event (Oliver 2009).
The greatest disadvantage for all of these products is the cost, compounded by very few insurance companies covering any expenses, although some are starting to. DexCom is slightly more costly, but its sensor lasts the longest. And of course, the parts are not interchangeable from the different manufactures. The receiver and transmitter have a year warranty, but can last up to 18 months. The receiver is battery operated with an overnight electric charger, much like a cell phone. The transmitter costs around $300, the receiver around $400, and the sensor $50 to $70 each, the DexCom more because it lasts longer. The adhesive patches are about a dollar each (medronics, abbott, dexCom 2010).
For this product to be effective in our perioperative setting, there would need to be several transmitters and receivers in the OR, one per room, in addition to several in the pre and post op areas. The initial investment would have to be repeated on an annual to semiannual basis, in addition to the weekly costs of the disposable sensors and patches. Unless the patient happens to have the same product at home use, he would not be able to utilize the sensor once discharged from the hospital.
Proposal
Because these 3 companies are well established, reputable and financially stable, and their products are so similar in quality and expense, and insurance companies are beginning to cover some of these costs, a proposal will be extended to each of these companies for the best pricing and company support, with the hope that competitive marketing can work toward our hospital’s most equitable investment, and our clients financial advantage.

Interseting subject matter. We poke our patients all of the time in ICU and even as frequently as q30-60 minutes when on an insulin drip, and having to correct hypoglycemia. Will be interested to see the results.
ReplyDeleteI got a little lost in the amount of historical info that was posted on all of the individuals from the diffent companies.
Keep up the good work as you tackle this project on your own. Let me know if I can help in any way.
This is an excellent RFP! I agree with Winnie above, that the historical info may not be quite necessary for the purpose of this assignment - but the document is very well organized, and I absolutely enjoyed the fact that not only have you listed all the facts of the vendors but you have carefully analyzed and investigated advantages vs. disadvantages and show detailed comparisons of the various systems. It is evident that you have done extensive research and have digested all the information you've gathered to produce this document. Keep up the great work!
