Maintaining the Medication Cold Chain in a Large Ambulatory Practice

By Will Bachman, MEd, PMP, CSM, Diane Garry, RN, BSN, MEd, and Mariam Gendi, PharmD, CPh

Introduction

Medications (including medication samples and vaccines) are commonly stored in office-based practices and must be stored under regulated environmental parameters to continuously maintain their stability, integrity and efficacy. Overcoming the medication management challenges faced in ambulatory care settings that lack direct support services of an integrated pharmacy creates challenges for ensuring the safe storage, handling, and transfer of medications. This article describes the process implemented at a large multi-specialty academic ambulatory practice located on the Gulf Coast of Florida to ensure that while the medications are being procured, stored, and/or transported to outreach locations the proper storage temperature is maintained.

Most medications are stored at ambient temperature (15ºC – 25ºC) while other medications may require refrigeration (2 ºC – 8ºC) or freezing (-15ºC and -25ºC). Occasionally ultra-low temperatures (below -50ºC) may be required. Medications that require refrigeration or freezing are often referred to as “cold chain” medications. The Centers for Disease Control and Prevention (CDC) defines a “cold chain” as a temperature-controlled supply chain that includes all vaccine-related equipment and procedures (CDC, 2024). The cold chain begins with the cold storage unit at the manufacturing plant, extends to the transport and delivery of the medication and proper storage at the provider facility, and ends with administration of the medication to patients.

The process for ensuring that medications are stored according to the manufacturer’s instruction for use is the responsibility of each organization. Failure to comply with temperature control regulations can result in the risk of a patient receiving a medication whose efficacy and safety have been compromised. There may also be the risk of financial loss and legal consequences for the organization as well as the risk of loss of credibility for healthcare providers.

Development of the process

An assessment of our practice sites revealed that there were variations in the process for monitoring temperatures, the type of refrigerators/freezers being used (e.g., household and medical grade), the process for identifying and managing a temperature excursion and in the receipt of receiving medications at the practice site. Complicating matters is the over 30 different geographic locations of our ambulatory practice in Florida, a state that is subject to environmental extremes and natural disasters increasing the need to eliminate process variation. Additionally, medications arrive at our centralized warehouse and are then distributed to the designated ambulatory location, increasing the importance of establishing a highly reliable process for maintaining the cold chain during transit.

To address these concerns, a standardized process was developed for maintaining the cold chain in accordance with state regulations and the manufacturer’s handling instructions. When developing the process, we integrated several regulatory requirements from the state of Florida, such as those for Health Care Clinic Establishment (HCCE) permits as well as from the Florida Board of Pharmacy for institutional pharmacy permits. We incorporated evidence-based practice recommendations obtained from the World Health Organization (WHO) Annex 9 Model Guidance for the Storage and Transport of Time-and Temperature-Sensitive Pharmaceutical Products (TTSPPs) (World Health Organization [WHO], 2011) and findings from recent assessments of WHO cold chain conformity in health facilities (Nyirimanzi, Ngenzi, Kagisha, Bizimana, & Kayitare, 2023). Our standardized process reflects current regulatory standards and best practices, with a strong emphasis on maintaining medication integrity, efficiency, quality, and efficacy while ensuring patient safety.

This process incorporated the use of reliable storage solutions (such as medical-grade refrigerators and freezers) and digital data loggers (DDLs) for continuous temperature monitoring. Trained personnel were designated and accountable for receiving medications and overseeing this standardized process for temperature control. Additionally, the process included targeted procedures to address key improvement areas identified in our initial needs assessment, such as ensuring proper storage in ambulatory care setting, managing temperature excursions and monitoring temperatures during the transport of medications.

All medication refrigerators are monitored using standardized DDLs along with twice-daily manual temperature checks—preferably at the start and end of each business day. Recorded temperatures are documented on a log, which is a standard practice in ambulatory care settings. In addition to twice-daily manual temperature documentation, DDLs provide the added benefit of continuous temperature monitoring and recording. This ongoing data collection offers critical insights to support informed decisions related to the handling, transportation, and storage of temperature-sensitive medications.

In our experience, after the placement of the DDLs, temperature excursions were detected in the household-grade storage units occurring during non-working hours, typically coinciding with the units’ automatic defrost cycles. As a result, the household refrigerators and freezers were taken out of service and replaced with medical-grade units throughout all clinical spaces.

In the event of a temperature excursion, the clinic manager is expected to promptly remove and quarantine any medications stored in the affected unit and notify the Medication Safety Manager (MSM), a licensed pharmacist. The MSM or designee is available to provide immediate guidance and support whenever a team member identifies a potential excursion. Medications suspected of having been exposed to an excursion are immediately sequestered until the analysis of the excursion is completed. If the medication can still be used, the MSM in collaboration with the medical staff team member evaluate any potential impact on patients and oversees the disposal of any compromised medications when necessary.

In our setting, most of our clinics are staffed primarily with medical assistants and some licensed practical nurses and registered nurses. We observed variability in team member knowledge and attitudes regarding cold chain management, similar to findings in other healthcare contexts where knowledge, attitudes, and practices vary significantly among staff (Asamoah, Ebu Enyan, Diji, & Domfeh, 2021). While most team members verbalized the importance of temperature monitoring, adherence to twice daily check-ins of medication storage units was not consistent. We determined there was an opportunity to improve team member knowledge and attitudes regarding cold chain management best practices through a revised standard operating procedure (SOP) supported by interactive e-learning. This approach reinforced consistency in carrying out these processes to ensure medication safety.

E-learning module

The e-learning module was developed to train clinic managers, as well as other ambulatory healthcare workers, on best practices for maintaining the cold chain. Built in Articulate Storyline, the module integrates evidence-based instructional strategies from cognitive psychology and educational technology to maximize retention, understanding, and practical application.

The module’s learning objectives were restructured using the SMART (Specific, Measurable, Achievable, Relevant, Time-bound) framework and aligned to Bloom’s revised taxonomy. This ensured clarity in expectations while supporting the development of higher-order thinking skills. For example, learners are asked not only to recall temperature ranges but also to analyze refrigeration issues and apply contingency planning steps. Such alignment improves focus and self-regulated learning by setting transparent cognitive targets (Hattie & Timperley, 2007). In healthcare training, designing objectives at the application and analysis levels ensures knowledge is transferred into real-world clinical behavior (Mayer & Fiorella, 2014).

To promote deeper learning, the transcript was revised using Patti Shank’s 28 evidence-based tactics. Medical terminology was simplified or explained, sentences were made shorter, and the overall tone was direct and conversational. This approach minimizes extraneous cognitive load, an essential consideration when designing for adult learners with limited time and attention (Shank, 2017). Emphasis was placed on the most critical content areas using headings, lists, and plain language. These techniques have been shown to improve comprehension and retention, especially when dealing with high-stakes technical topics like temperature excursions or digital data logger calibration (Clark & Mayer, 2016).

Mayer’s 12 multimedia principles guided the visual and interactive elements of the course. We applied the coherence principle by excluding decorative or redundant content and instead presented focused visuals like storage diagrams in tandem with spoken narration. The modality principle was applied by using narration instead of text when visuals were shown, avoiding split attention and reducing cognitive load. These approaches leverage dual-channel processing, enabling deeper encoding of the material into long-term memory (Mayer, 2009). The segmenting principle was implemented to address the complexity of medication temperature management procedures. Learners could proceed slide-by-slide at their own pace, with complex processes like cold chain equipment set up divided into discrete, manageable steps. Each segment included clear transition points and a “continue” prompt to support self-paced learning. This approach has proven particularly effective for technical healthcare content where procedural accuracy is critical (Mayer, 2009).

Voiceover was generated using AI-based narration technology. Narration adhered to Mayer’s voice and modality principles by offering clear, natural-sounding speech in place of written text (Moreno & Mayer, 1999). While earlier research by Clark and Mayer suggested learners typically respond better to real human voices, recent studies by Sweeney et al. indicate that advances in AI have narrowed this perceptual gap significantly (Sweeney, Zhang, & Peterson, 2023). In comparative evaluations, contemporary AI-generated narration has shown engagement metrics comparable to human narration, particularly when optimized for prosody and pacing (Johnson & Miller, 2022). Using synthetic narration provided a scalable, editable, and high-quality solution that aligned well with learner needs while still fostering engagement and retention.

To further enhance retention and application, the module includes comprehension checks after each major topic. These low-stakes assessments include tailored feedback—explaining not just which answers are correct, but why. This form of corrective feedback is known to improve performance, especially when aligned closely with learning objectives and when provided immediately (Narciss, 2014). For example, if a learner incorrectly identifies the acceptable temperature range for frozen vaccines, the module explains the mistake and reinforces the correct range. These retrieval practices enhance retention and build learner confidence.

The Medication Temperature Management module was developed with an emphasis on evidence-based instructional design. By aligning objectives with Bloom’s taxonomy and the SMART framework, simplifying the transcript using Shank’s writing strategies, designing multimedia elements around Mayer’s principles, and integrating responsive AI narration and formative assessments, the module fosters deep learning and practical application. In high-risk clinical contexts, training that supports retention, judgment, and procedural accuracy is not optional – it is essential. This e-learning experience represents a replicable model for high-impact, scalable education in healthcare systems.

Safety reporting

Applying high reliability concepts in our organization has been paramount to our success. Safety reporting is encouraged and supported. All excursion events are entered into our safety reporting system for analysis and tracking. Team members involved in a medication excursion event participate in determining system level factors that contributed to the event. During medication safety rounds we acknowledge and appreciate team members who are routinely monitoring their temperatures. When excursions or near-miss excursions occur we are transparent about the event and share our findings at team meetings and during our Medication Safety Committee meetings. To improve leadership accountability, medication storage temperature monitoring is incorporated into the daily leader standard work tool. The MSM regularly reviews the monthly DDL reports to monitor any missed excursions. While adoption of these strategies has significantly improved medication safety, we plan to move to having a centralized repository for the DDL data so that we may receive reports of temperature fluctuations in real time and act on them before they become an excursion.

Conclusion

In the absence of an integrated pharmacy service, the risks to the process are many, but a strategy of proactive risk assessment and mitigation has enabled our organizations’ cold chain process to be more resilient. Maintaining best practices in cold chain management requires a well-structured process that includes all team members involved in the procurement, storage, and administration of medications. Implementing improvements to the level of supervision, Standard Operating Procedures (SOP) implementation, team members education, improved technology and ongoing monitoring and support have strengthened our adherence to best practices in cold chain management.
