CAAS and CAMTS Accreditation: How USP Good Distribution Practices Come into Play

The business of emergency medical services is all about saving lives. That includes having the best-trained staff and most current technology and equipment to ensure both the fastest response times and the best patient outcomes. But, as you know, there’s so much more that goes into maintaining the highest quality of care – even down to the seemingly smallest detail, like keeping medications within the ideal temperature range.

There are a variety of standards that EMS organizations can use to make sure they are up-to-date with industry best practices where safe temperatures are concerned. However, most accreditation agencies rely heavily on US Pharmacopeia (USP) for best practices on shipping and storing pharmaceuticals. And while not required, many EMS providers seek accreditation as a point of differentiation and illustration of best practices from one or both the Commission on Accreditation of Ambulance Services (CAAS) or the Commission on Accreditation of Medical Transport Systems (CAMTS).

If you are considering working toward accreditation – understanding USP guidelines from the outset could help the process go a bit more smoothly for you. That’s because both require procedures be in place for monitoring the temperature of medication in storage and vehicles, and both also base their standards on USP guidelines.

The Story Behind USP

USP has had standards in place for many years around the best practices for shipping and storing pharmaceuticals. USP Chapter 659 Packaging and Storage Requirements, for instance, provides definitions for appropriate and various packing materials as well as storage conditions. This includes temperature definitions for frozen, refrigerated, cold, cool, room temperature and controlled room temperature. There is also information related to allowable temperature excursions and how best to measure and track temperature, all to protect the integrity of drugs as well as ensure patient safety.

More recently, as the industry has been working toward Good Distribution Practices, the USP updated their guidelines to include Chapter 1079 Good Storage and Distribution Practices for Drug Products. This informational chapter builds on the definitions provided in the earlier Chapter 659 and is used as guidance for all organizations and individuals involved in any aspect of the storage and distribution of all drug products, including Emergency Medical Services.

The Commission on Accreditation of Ambulance Services

As noted, CAMTS includes air transportation in its standards in addition to ambulances, vans and other ground EMS vehicles. In the tenth edition of their accreditation standards, updated in October of 2015, the CAMTS states in Section 03.06.00, Page 3.27 and 3.28:

Storage of medications allows for protection from extreme temperature changes if environment deems it necessary. If there is a refrigerator on the vehicle for medications, a temperature monitoring and tracking policy is required, and the refrigerator is used and labeled ‘for med use only.’”

“Determination of when the blood product was released from the Blood Bank. Blood must be maintained at a controlled temperature of 2-8 degrees C during transport and must be infused within 4 hours of removal from ther­mal control. The temperature of the cooling mechanism is monitored and recorded.”

A Case in Point: Walton County Fire Rescue

Walton County Fire Rescue is a 130-member department providing fire suppression and prevention as well as emergency medical services in Walton County, Florida. Working out of 11 stations, the highly trained crews serve people living in a 760 square mile area north of the Choctawhatchee Bay.

In 2019, Walton County Fire Rescue began working toward earning certification from CAAS. Among the requirements for certification is the ability to verify that medication and devices stored in stations and carried in emergency vehicles are kept within compliant temperatures, as outlined by the manufacturer and referenced in USP Guidelines, explains Tim Turner, Division Chief of EMS Training, Walton County Fire Rescue.

For much of the medication the Fire Rescue crews carry, this means either refrigerated temperature (36⁰F to 46⁰F) or controlled room temperature (68°F to 77°F). “While our medications were all kept in a climate-controlled environment, we had no formal process in place for monitoring and recording temperature data,” Chief Turner says. When he and Kayleigh Sanders, the organization’s Accreditation Clerk, began talking to other EMS providers about what they were doing to monitor and record temperatures – they found that many were doing it manually. Overall, says Chief Turner, the results did not seem to be meeting CAAS standards. That’s when Walton Fire Rescue decided to look for a more automated, reliable process.

The Benefits of Automated, Wireless Temperature Monitoring

An S-400 wireless sensor in a medical container with vialsThe team settled on a comprehensive solution that includes 60 wireless, Bluetooth®-enabled sensors to monitor medication in storage areas on rescue vehicles, in drug bags and in supply rooms. That includes supply closets and refrigerators at each of their 11 stations as well as on their six primary ambulances where they have a sensor in each StatPack™ and cooler.

Fifteen corresponding wireless gateways were also installed, which collect data when vehicles return to the station and store it in the cloud where it can be easily accessed or downloaded for generating reports. A gateway is also installed directly on the two EMS vehicles. With gateways in these ambulances, the Fire Rescue team can get alerts in real-time while crews are in the field. If that happens, they can quickly log in to the free mobile app or web-based system to see exact temperature exposures as they are happening.

Since everything is automated and cloud-based, they don’t need to rely on crews to log correct temperatures “It just takes stress away from crews, which is important so they can concentrate on saving lives and putting out fires,” says Chief Turner. In addition to using the temperature monitoring system to earn accreditation, Chief Turner says the sensors are invaluable also because they give him and his crews a new level of confidence in the efficacy of the medications they administer.

Technology Streamlines Compliance Reporting

Wireless sensors can be programmed from a smartphone or tablet using a mobile app. This allows users to set preferences such as alarms, datalogging intervals and startup options as well as time and temperature units. Mobile apps also make it easy to access temperatures, locations and other information captured by the wireless sensor.

Using the free mobile app, temperatures and alarms can be viewed on demand.

A web application with a sophisticated dashboard gives users a consolidated snapshot of data uploaded from sensors to the cloud. This allows users to view and manage all information, including temperatures, the location where sensors were read and any alarms that might have occurred. Data can easily be exported to PDF or CSV files to generate detailed reports of sensor readings, events and settings for internal tracking as well as to meet CAAS and CAMTS requirements. According to Shaun Curtis, Support Services Manager for Medstar Mobile Healthcare in Texas, reports are detailed enough that compliance with temperature monitoring has been the easiest part of their CAAS audits – which take place every three years.
