Reliance Rx: Year-round Facility Monitoring to Verify Medication Temperatures


Reliance Rx is a full-service specialty pharmacy that provides necessary biologics, oral oncolytics, disease-modifying and ancillary specialty pharmaceuticals to patients across the country. Their mission is to provide the highest-quality specialty pharmacy experience to their patients – which includes promoting positive patient outcomes and efficient use of specialty services. The organization had long been monitoring temperatures of medication stored onsite, but as technology advanced they were interested in upgrading their processes for a more automated solution with Temptime’s W-200 wireless sensors.

Business Challenge

At one time, Reliance Rx used a T1 line – an early form of communications transmission and data connectivity – to monitor power outages and temperature excursions. As technology advanced, however, the specialty pharmacy saw the opportunity to add a wireless solution. “We felt this would give us greater visibility into exact temperatures and provide further continuous monitoring,” says Tim Carroll, PharmD, Vice President, Pharmacy Operations and Business Development

Reliance Rx had been using Temptime’s TransTracker® temperature indicators for patient shipments. These single-use indicators give patients an easy-to-read visual cue of whether their medication has gotten too hot or too cold during transit. Based on this established relationship and Temptime’s knowledge of the specialty pharmacy’s cold chain monitoring needs, Tim says they turned to the company for guidance.

The solution they chose was the W-200 wireless sensors along with a wireless gateway and web-based dashboard application.

Benefits At-a-Glance: W-200 Wireless Sensors

  • Monitors both temperature and relative humidity for CRT, refrigerated and frozen environments
  • Individual sensor configuration and NIST probes for precise calibration
  • Alarm alerts and notifications of temperature or humidity excursions
  • Easy setup and remote temperature access via a web-based application
  • Compact design, long battery life and low-cost connectivity using LoRaTM, the latest technology for the Internet of Things (IoT)

The Solution

Reliance Rx now uses five W-200 wireless sensors to monitor medication temperatures and relative humidity in drug bays and refrigerators. “We conducted a yearlong demo of the devices to make sure they met our internal standards,” explains Tim. This included a move to a large scale fulfillment site where the W-200s were used as an integral part of their temperature and monitoring strategy.

Each sensor can be programmed individually with different temperature and humidity highs and lows, making them customizable for every type of medication storage environment. A wireless gateway gathers data from the sensors and uploads it to the cloud for easy access to temperature profiles and history via a web-based dashboard.

The Result

One of the best features for Reliance Rx, says Tim, is how easy the devices are to program using the web application dashboard. “We were able to install the gateway and program the sensors on our own, but when we do have questions – Temptime is always responsive and provides thorough and thoughtful support.”

Beyond that, he adds, the W-200 delivers peace-of-mind knowing a precise, NIST verified temperature readout is available. Ensuring that readout is correct is a critical step in the cold chain process. “Online access to data has given us the ability to make remote decisions instead of always having to physically go to the facility after hours.”
