Old age supportGrowing older is complicated. No two people will age in the exact same way, from the physiological changes they experience to the types of comorbidities they have to the ways their bodies absorb medications. This makes geriatrics care particularly intricate to navigate and highlights pharmacists’ pivotal role in team-based care. It also means that geriatrics education must focus on ensuring that students understand the nuances regarding prescribing and medication safety for older adults.

“Healthcare professionals working in geriatrics tend to be leaders in interprofessional collaboration because it’s so complicated. As you age you get more complex, you have more disease states and there are medication interactions to consider. Interprofessional collaboration is key,” explained Dr. Teresa DeLellis, chair, Department of Pharmacy Practice, Manchester University College of Pharmacy, Natural & Health Sciences. “Education starts with understanding what aging does physiologically to how the body handles medications. It requires knowing the pharmacology of each of these medications and the expected side effects, or knowing if the answer is not a medication.”

DeLellis is part of a team that is developing guidance for pharmacy programs regarding the concepts that every entry-level pharmacist should know about geriatrics. The team is also exploring best practices for teaching these topics in the most effective way. She and her colleagues are partnering with the American Society of Consultant Pharmacists, which has published a geriatric curriculum guide, as well AACP and some other American and Canadian pharmacy organizations to pull from their collective knowledge. “Unless you are in pediatrics, you are going to care for older adults,” she pointed out. “We are doing a literature review to see what pharmacists are doing in patient care right now, what are the pharmacy practice models and health outcomes associated with those. That will help us see what to prioritize in the Pharm.D. curriculum.”

Care givers

According to Census Bureau data, about one in six people in the United States were 65 or older in 2020—close to 17 percent of the population. That figure is expected to rise to 23 percent by 2050. A broader focus on geriatrics education in pharmacy can help students understand how physiology changes as people age, how response to medication changes and how best to communicate with older patients and their caregivers.

A Robust Curricular Commitment

The Virginia Commonwealth University (VCU) School of Pharmacy has made an intentional effort to keep geriatrics integrated in the curriculum so student pharmacists are exposed early and often to concepts related to caring for older adults. Students also have an option to pursue a Certificate in Aging Studies dual degree, thanks to a 30-year partnership with the Department of Gerontology. That commitment to geriatrics education recently earned the pharmacy school recognition from the Academy for Gerontology in Higher Education (AGHE) as a Program of Merit for Health Professions, making it the first Pharm.D. program in the country to receive the designation.

In addition to a geriatrics pharmacy elective and an APPE rotation in geriatrics, “one big thing we offer is a lot of opportunities for research and independent study with faculty,” said Dr. Emily Peron, associate professor. “We have five pharmacy faculty on board who are geriatrics trained. We offer projects for students who are interested in exploring the topic further. The gerontology faculty are instrumental. There’s a lot of overlap and collaboration with them.” She noted that the collaboration extends to several other schools within VCU.

“We have a nursing faculty that we consider to be part of our team that is working on related issues, as well as folks from medicine, occupational therapy and physical therapy. There are interprofessional offerings and clinics where we all work together in the community, plus a virtual case that all medicine, nursing and pharmacy students complete that is teamwork-based,” Peron said. “We’re starting to see growth in terms of community engagement. We’re partnering with societies and student interest groups. Sharing responsibilities makes it a richer experience for everyone.”

Dr. Patty Slattum, interim associate dean for research and graduate studies, added that the program was able to flourish thanks to a dean in the 1990s who championed the idea of hiring faculty who specialized in geriatrics. “Having the leadership that says this is important and we’re going to build something with that, probably that is what got us to the place where we could get the recognition from AGHE,” she said. “You look across many courses, and the pieces that are important to the care of older adults are included, and people with geriatrics expertise are teaching them. These are things that help our graduates become better prepared to care for older adults with complex medication needs.”

VCU prioritizes interprofessional education, with three required IPE courses built into the pharmacy curriculum. “If students are in the community clinics where faculty work, they can do rotations and get hands-on experience working with older adults,” Peron noted. “It’s vitally important to our students to be able to work interprofessionally. The system does work better that way to care for older adults. Patients’ needs can vary significantly. There are lots of opportunities for healthcare professionals to identify different issues as they come up.”

Senior Care

Older adults tend to present many complexities as patients, so student pharmacists need to be prepared to take those into account when it comes to therapeutic decision making, Slattum noted. “We see older patients experiencing adverse social determinants of health. How is that playing into chronic conditions and things like payment for services? We want students to be able to deal with that complexity and be comfortable through that decision making,” she said. “We also want students thinking about how you deprescribe drugs. We have a much bigger focus on that in this population. There are complexities of settings where care is delivered. You are dealing with assisted living or a family caregiver environment, and so how do you work through those as a healthcare professional?”

Peron added that the curriculum also encourages students to examine ageism in the healthcare system. “Pain gets overlooked in older adults,” she pointed out. “We tell students to look out for the phrase ‘what do you expect at this age?’ A big push we have is helping [future pharmacists] use terminology that’s appropriate and think more critically about choices they are making or whether they are making an assumption based on age. We want to ensure that we are doing what’s best for the individual patient. It’s not one size fits all. We want to dispel myths about aging and make working in geriatrics something that’s really making a difference.”

Slattum hopes to see more pharmacy schools pursue the AGHE designation and embrace working with this population. As Peron noted, “It may not seem like a sexy specialty, but there is so much value pharmacy can add to working with older adults. It’s a great opportunity for schools of pharmacy to identify areas of need. We need more healthcare professionals working in geriatrics. As people take more medications, pharmacists are going to be one of those groups that provide additional assistance in that realm.

Senior care

 

“There’s a fear of our own aging that can prevent us from looking at ways to make changes in care,” she continued, noting that she hopes other schools will consider expanding geriatrics opportunities. “The tenets of how we operate apply across the board. One special thing about geriatrics is that you are specializing in working with a population, but it allows you to work across many different practice settings. It’s a robust opportunity for pharmacists.”

Safety First

From Dr. Joseph Zorek’s perspective, integrating key concepts of geriatric pharmacotherapy throughout the pharmacy curriculum to weave in a deliberate focus on older adults would be ideal. Zorek, professor and executive director of Linking Interprofessional Networks for Collaboration at the University of Texas Health Science Center at San Antonio (UT Health San Antonio), teaches advanced pharmacotherapy to graduate nursing students and leads the university’s effort to advance IPE. “Older adults take lots of medications and have lots of comorbidities,” Zorek noted. “You would be hard-pressed to find an older adult who would not benefit from an interprofessional, team-based intervention.” The role of caregivers in this population adds another layer of complexity and challenge optimizing medication use. He added, “caregiving is really an ideal scenario to explore how important it is for different healthcare professionals to be working as a team.”

“The days of practicing in a silo are pretty much over in the vast majority of pharmacy practice settings. You have to be knowledgeable about other professionals. You have to be an advocate for yourself within the healthcare team. Many of the most rewarding pharmacy practice ventures have interprofessional aspects to them.”

At UT Health San Antonio, students participate in several large-scale IPE activities that leverage care-based learning rooted in real-world examples. In one of these IPE activities, students are put on interprofessional teams to conduct a simulated telehealth visit with the caregiver of an older adult living with dementia. Experiencing the difficulties faced by a family caregiver, including challenges with medication management, illustrates why team-based care is crucial. “You can’t really practice pharmacy without figuring out how you fit into the complex ecosystem of healthcare,” Zorek said. “The days of practicing in a silo are pretty much over in the vast majority of pharmacy practice settings. You have to be knowledgeable about other professionals. You have to be an advocate for yourself within the healthcare team. Many of the most rewarding pharmacy practice ventures have interprofessional aspects to them.”

Manchester’s DeLellis pointed out that pharmacists play a particularly important role when it comes to transitions of care. Establishing and maintaining medication histories is vital to prevent inaccuracies and errors. “At the beginning of a transition, pharmacists help determine what medication management should look like as we think about getting patients to the next place, and then they are involved at intake there,” she explained. “Patient education is a huge part of that. A lot of these medications will be self-managed. There have been a lot of impressive outcomes proven from pharmacists doing post-transition follow up after hospital discharge. A lot of errors have been caught and prevented that way. And it has saved hospitals a ton of money.”

“Education starts with understanding what aging does physiologically to how the body handles medications. It requires knowing the pharmacology of each of these medications and the expected side effects, or knowing if the answer is not a medication.”

Dr. Sunny Linnebur, professor, Department of Clinical Pharmacy, University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences, who also practices at a primary care clinic serving patients over 75, is focused on drug safety and deprescribing. “What I want students to understand is when you give a medication to a 40-year-old it has one outcome, but for an 80-year-old it can have a completely different outcome,” she said. “There are adverse reactions that can lead to hospitalization. We have to be careful and thoughtful about medications in older adults.”

Linnebur teaches students to look at kidney dysfunction as something that can affect many disease states in the geriatric population and that may require medication adjustment. “I teach a lecture on pharmacokinetics in older adults. I want students to be aware of drug-drug interactions with older patients and making sure they are providing safe dosages.”

With many patients having complicated polypharmacy situations, pharmacists are ideally positioned to help optimize medication therapy. Sometimes that means understanding which medications to take away, which Zorek agreed must be a component of geriatric pharmacy education. “Polypharmacy is associated with numerous negative outcomes. It correlates with depression, for example, and falls. [Pharmacy schools] need to hone in on the safety of medications,” he emphasized. “As individuals age, changes in our bodies lead to predictable changes in the pharmacokinetics and pharmacodynamics of medications. If you’re not paying close attention to the age-related physiological changes, you are likely to run into issues with medication management. Pharmacist-led deprescribing services have become quite popular, with several widely used tools available to help assess the appropriateness of medications.”

It Takes a Team

Given the large percentage of older adults in the United States and the rapid increase in medication use, Linnebur said, it would be smart for pharmacy schools to prioritize geriatrics education to train students to understand the needs of older adults. “One of the growing areas of clinical practice is ambulatory care specifically working with Medicare patients,” she noted. “We are able to bill for Medicare wellness visits. We are also starting to be able to bill for continuous glucose monitors in outpatient clinics. You can bill for other Medicare visits as well. In the past we have done billing through Medicare Part D. One of the growing areas of clinical practice is working with these patients over 65. If we are expecting pharmacy graduates to practice in an ambulatory setting and bill for services, then we need to train the students to have the skill sets and ability to work with that patient population.”

She credited the American Geriatrics Society, an interprofessional organization, with helping to ensure that pharmacists are at the table and part of the discussion about decisions related to the care of older adults. To recognize how the skill sets of multiple providers come together and how an interprofessional approach benefits older patients, Linnebur recommends having students shadow other team members such as physicians, nurses and social workers, or asking team members to teach in a pharmacy course.

This ties back to the need for team-based care in geriatrics. As Zorek pointed out, “Older adults don’t take medications in a vacuum. The advice and actions of numerous health professionals impact patients’ medication regimens and their medication-taking behaviors. To use medications safely, pharmacists have to understand and engage with these clinicians. For example, sharing concerns, providing recommendations, and coordinating efforts with physicians, physician assistants, nurse practitioners, dentists, physical therapists, social workers and many others to improve any given older adult’s care. It’s impossible to practice pharmacy without a good understanding of interprofessional dynamics.”

DeLellis hopes to see a more consistent emphasis on geriatrics across the board, which will help break down societal barriers. “We have ingrained in society a subtle ageism: it’s terrible, it’s depressing, so no one is interested in caring for older adults. We need to destigmatize aging and focus on how important this type of care is to ensure that aging doesn’t have to be a negative experience.”

As Linnebur noted, “Working in geriatrics is really rewarding. The providers are some of the best people to work with, and the quality of work life is really high when you work with older adults.
