Grace Medical Center Uses ZulaFly RTLS to Prevent Food, Medication Loss

The system, which utilizes CenTrak sensors and access points to capture temperature readings within each of 18 coolers, has already prevented the spoilage of $15,000 worth of food in a walk-in refrigerator since its installation in August.

Grace Medical Center uses the cloud-based software to set the temperature thresholds according to the needs of the medications or food items stored within each unit. If the captured temperature reading is found to be above or below the acceptable threshold, the Fuzion software issues an alert to the department manager, either via text message or e-mail. If the cooler has not returned to the acceptable range, or if a remediation has not taken place (such as closing the door) within two hours, the software contacts a medical center manager.

Since installing the technology, Winn reports, the hospital has learned details regarding how its coolers operate, as well as daily activity around the units. For instance, he says, it discovered that one refrigerator was dropping below freezing, and its own temperature sensor had not been detecting that deviation because the hospital didn't expect the refrigerator to get that cold and therefore had not configured its previous sensor system accordingly.

Placed inside each cooler is a temperature probe housed in a small bottle filled with propylene glycol and wired to a CenTrak tag mounted to the unit's exterior.
By installing two sensors within the walk-in refrigerator, the hospital learned that the temperature readings had previously been inaccurate, since the blower was pushing cold air toward the thermometer while other parts of the cooler were too warm. It also determined the times of the day during which the refrigerator was warming up, such as at night while it was being restocked.

Based on that information, Grace Medical Center has altered its walk-in cooler restocking process. Now, all temperature-sensitive foods are brought to a staging area near the refrigerator before being loaded into it, so that the door does not remain open for a lengthy period of time.

The combination of RFID data systems with Bluetooth or other sensor technologies is an easy win for providers investing in RFID. www.AirFinder.com is an example of a system that works with generic Bluetooth technologies.
