Medical student education program in Alzheimer’s disease: The PAIRS Program
BMC Medical Educationvolume 12, Article number: 80 (2012)
As life expectancy increases, dementia incidence will also increase, creating a greater need for physicians well-trained to provide integrated geriatric care. However, research suggests medical students have limited knowledge or interest in pursuing geriatric or dementia care. The purpose of this study is to evaluate the PAIRS Program and its effectiveness in enhancing medical education as a service-learning activity and replication model for the Buddy ProgramTM.
Between 2007 and 2011, four consecutive classes of first year Boston University School of Medicine students (n = 45; 24 ± 3 years, 58% female, 53% White) participated in a year-long program in which they were paired with a patient with early-stage Alzheimer’s disease (AD). Assessments included pre- and post-program dementia knowledge tests and a post-program reflective essay.
Program completion was 100% (n = 45). A paired-sample t-test revealed a modest improvement in dementia knowledge post-program (p < 0.001). Using qualitative coding methods, 12 overarching themes emerged from the students’ reflective essays, such as observing care partner burden, reporting a human side to AD, reporting experiences from the program that will impact future clinical practice, and obtaining a greater understanding of AD.
Quantitative and qualitative findings suggest that the PAIRS Program can enhance the acquisition of knowledge, skills, and positive attitudes regarding geriatric healthcare in future generations of physicians, a skill set that is becoming increasingly relevant in light of the rapidly aging population. Furthermore, results suggest that The Buddy ProgramTM model can be successfully replicated.
Alzheimer’s disease (AD) affects an estimated 5.3 million older Americans . While there are a number of pharmacological and non-pharmacological approaches that have been shown to effectively treat AD symptoms, there is no proven treatment to prevent, arrest, or reverse pathophysiological changes associated with the disease [2–5]. Given the complexity of AD diagnosis and management, it is not surprising that approximately one third of general practitioners find clinically managing dementia more frustrating than rewarding  and a similar number report the dementia diagnosis is the responsibility of a specialist . However, older adults receive the majority of their healthcare from primary care physicians , who report pessimistic attitudes toward dementia care , including difficulty establishing a definitive diagnosis , discomfort discussing diagnosis and care options , and lack of community and social service referral information [9, 10]. Unfortunately, a majority of medical students report similar barriers with limited knowledge about aging , mixed attitudes toward older adults [12, 13], and limited interest in pursuing geriatrics or dementia care [13, 14]. Early exposure may increase comfort with older patients [15, 16].
The Boston University Partnering in Alzheimer’s Instruction Research Study (PAIRS) Program is one unique service-learning program aimed at enhancing geriatric healthcare issues in medical education. The program’s student-focused objectives include: (1) educating students about AD and related cognitive impairment; (2) familiarizing students with care and support-related issues patients and their families encounter; (3) improving students’ communication skills with elders and cognitively impaired individuals; and (4) introducing students to career opportunities in geriatrics and related fields.
The PAIRS Program is the first educational initiative to replicate the Northwestern University Buddy ProgramTM. The current study aims to quantitatively and qualitatively evaluate the PAIRS Program in fulfilling the four learning objectives outlined above. We hypothesized that dementia knowledge would quantitatively increase post-program and that qualitative analysis of end-of-the-year reflective essays would yield themes aligned with the PAIRS Program objectives.
Starting in 2007 and repeating annually, first year Boston University medical students were invited to apply to the PAIRS Program, which included a written application and interview process. In September, students were selected for participation based on enthusiasm, professionalism, and commitment level for the program requirements across the academic year. Selected students completed pre-program dementia knowledge tests upon program enrollment (i.e., prior to training). Students then participated in three hours of formal lectures on AD and dementia fundamentals and communication skills for interacting with aging and cognitively impaired adults. Students were paired with an early-stage AD “buddy” (taking into consideration shared interests and geographical proximity) and introduced to their “buddy” at a Match Day event in October. Between November and May, the “pairs” met monthly for a minimum of four hours and participated in social and cultural activities, such as dinner or visiting a museum. Students reported reactions via activity journal entries and attended monthly luncheons to receive supplemental education from guest lecturers (e.g., AD diagnostics, neuropathology) and share experiences with each other and program staff. Students completed post-program dementia knowledge tests following the final program meeting in May. Students received elective credit upon completion. The Institutional Review Board approved the use of program data for research and determined the research was exempt from written consent in accordance with federal regulation 45 CFR 46.101(1). While written consent was not obtained, all students provided assent to allow their de-identified program data to be used for research purposes.
The Buddy ProgramTMDementia Knowledge Test
A 33-item measure assessed dementia knowledge pre- and post-program . Scores range 0–33 with higher scores indicating increased knowledge.
The Boston University PAIRS Program Dementia Knowledge Test
In 2009, a 64-item measure was developed in an effort to more comprehensively assess dementia knowledge pre- and post-program. This measure was first implemented at the beginning of program year 3 and therefore completed by a subset of students enrolled in program years 3 and 4. Scores range 0–64 with higher scores indicating increased knowledge.
Students write an end-of-the-year essay reflecting on their PAIRS Program experiences, including what they knew about AD before beginning the program, what they learned during the program, and how their participation will affect their medical career.
Descriptives were generated for the student applicants and participants. Pre- and post-program knowledge scores were compared using paired-sample t-tests with a post-hoc item analysis. Analyses were conducted using SPSS 16.0 (Chicago, IL). Significance was set at p < 0.01 for primary analyses and p < 0.001 for post-hoc comparisons.
To qualitatively analyze the essays, Consensual Qualitative Research strategies were employed . Two staff (LB, NC) independently reviewed the essays from program years 1 and 2 (n = 22), developed major themes (domains), and coded content according to domains. The program director (AJ) provided feedback on overlap and discrepancies. Next, the coders came to a consensus on a final list of domains and core ideas within each domain. Finally, essays from program years 3 (n = 11) and 4 (n = 12) were analyzed by the two coders to verify that existing domains were saturated (i.e., no additional information was found that contributed to the understanding of the existing domains) .
Between 2007 and 2011, 4 program years were completed with 79 student applicants and 45 enrollees out of 700 total medical students enrolled between 2007 and 2010. Comparison of admitted (n = 45) versus not admitted applicants (n = 34) revealed no between-group differences for age (t(62) = −1.32, p = 0.19), sex (x 2 = 0.47, p = 0.49), education (t(77) = −0.47, p = 0.64), prior professional experience with an individual with AD (x 2 = 0.03, p = 0.87), or personal/familial familiarity with AD (x 2 = 0.96, p = 0.33). See Table 1.
Dementia knowledge test performance at program entry as assessed by the Buddy Program knowledge test was unrelated to students’ prior professional experience with AD (t(43) = 0.47, p = 0.64) or personal familiarity with AD (t(43) = 0.09, p = 0.93).
A post-program statistical improvement in knowledge was observed (t(44) = −6.3, p < 0.001). Inspection of mean pre- and post-program performances suggests an improvement of 2.5 items, corresponding to 7.5% enhanced accuracy (see Table 2). Post-hoc examination of items with the greatest improvement (i.e., p-values <0.001) suggests two key areas of increased learning. Students increased their knowledge about autopsy as the only method for a definitive diagnosis for AD (i.e., 36% accuracy pre-program versus 73% accuracy post-program) and the misconception that dementia is untreatable (i.e., 64% accuracy pre-program versus 91% accuracy post-program).
A post-program improvement in knowledge was also observed for the subset of participants (n = 23) who completed the Boston University PAIRS Program Dementia Knowledge Test (t(22) = −5.1, p < 0.001). Inspection of mean pre- and post-program performances suggests an improvement of approximately 4.5 items, corresponding to 7% enhanced accuracy (see Table 2). Post-hoc examination of items with the greatest improvement in accuracy (i.e., p-values <0.001) suggests several key areas of enhanced knowledge. Students increased their understanding of the symptoms of “sundowning” (i.e., 44% accuracy pre-program compared to 76% accuracy post-program) and their knowledge about risk factors for AD, such as educational attainment (i.e., 26% accuracy pre-program compared to 51% accuracy post-program). Similar to the Buddy Program Knowledge Test, students enhanced their knowledge about autopsy as the only definitive method for diagnosing AD (i.e., 39% accuracy pre-program compared to 74% accuracy post-program).
Essay themes are summarized in Table 3 and described below.
Reasons for joining program
Students joined the program to enhance their understanding of AD and develop clinical skills. One student explained: “I [joined]…because of the unique learning experience that it offered students to become involved outside of the classroom.” Another student wrote:
“I wanted to have some positive experiences with Alzheimer’s patients especially since I am interested in Geriatrics. I knew that [AD] impacts many people in the geriatric population and will continue to have a growing impact and therefore it was important to me to learn how to effectively communicate with this population.”
Previous scientific knowledge of AD
Previous AD knowledge was scientific and academic in nature. One student explained: “I didn’t know much about [AD] except for what I learned in school - memory loss, tau protein, tangles…a scientist view.” Another student wrote, “Prior to joining…I had a vague idea of the pathophysiology, but I had no knowledge at all regarding the personal and social impact of [AD].”
Previous experience with AD patient
Some students had limited prior experience with AD. One student wrote: “I had never met anyone who had [AD] or who was a caregiver for someone with it.” Students with personal familiarity described their experience:
“I can remember visiting [my grandmother] at the nursing home…at first she was very sociable, but after a few years…minor issues, such as turning off the bathroom light, progressed to major issues, such as remembering where she was…finally the day came when she forgot who I was.”
Initial impressions of buddy
Students had preconceived notions about their buddies. One student wrote: “At first, I did not see any major deficits. This was not the picture of Alzheimer’s that had been painted for me in my Biochemistry courses.” One student admitted: “My expectations of [his] capabilities were low…according to my initial perception of what AD was, he blew me out of the water every time I met with him.” One student confided: “I was nervous…about hitting it off with my buddy and being able to spend so much time with him, but we connected really well and I greatly looked forward to our outings.”
Observation of AD symptoms
One student reported: “I hadn’t known that long-term memory stays largely intact. [He] could tell me all about his days in the U.S. Navy…in pretty astonishing detail, but he couldn’t tell me what he had for breakfast.” Another student recalled: “He spent a lot of time trying to get the camera to work. At times the camera was upside down, or he would press the on/off button instead of the snapshot button.” Another student explained: “[He makes] inappropriate [jokes] or misunderstood jokes with strangers because he has forgotten the context.”
Greater understanding of AD
Through formal and experiential learning, students gained a deeper understanding of AD. One student remarked: “Before I started…I did know about different aspects of Alzheimer’s but not in any context; the program helped tie all my knowledge together while providing much more data – both scientific and experience related.” One student concluded: “[This] has been an incredible experience for me to learn about how far [AD] permeates into a person’s life, far beyond the signs and symptoms that the physician or neuroscientist witnesses.”
Students reported observing the physical and emotional strain of the caregiver. One student reported: “I hadn’t realized how draining being a caregiver can become. We hear about the strain on caregivers all the time, but it is another thing to see it right in front of you.” A student wrote: “At one point [my buddy’s wife] told me that he was a different person. It’s hard to completely understand what that’s like, in a way she was losing him while he was still there.”
Human side of AD
Witnessing the everyday impact of AD on the patient’s life revealed a humanistic side of the disease. One student wrote: “My buddy allowed me to see Alzheimer’s through his eyes [and] to better understand his difficulties, frustrations and concerns.” Another student reported: “It’s one thing to study how proteins in the brain affect cognitive functioning, it’s quite another to see how families deal with a fading husband or father.” One student stated: “As a first year medical student, I am so glad I had the opportunity to witness firsthand the personal side of a disease. Classes this year focused on scientific study of disease, but my personal experiences seem equally important.” Another student wrote:
“Medical students don’t always get such personal accounts, yet such experiences enrich our understanding [so] that we remember for future patients to treat the person as well as the disease, a concept that…sometimes is lost.”
Buddy and caregiver's hopeful outlook
Students were surprised by their buddy and family’s optimistic approach for coping with AD. Students wrote: “[His] upbeat attitude despite his often depressing illness was refreshing and motivating” and “[My buddy] is one of the strongest people I have ever met and she continues to keep a positive attitude in the face of her terrible disease.” Another student wrote:
“The way [they] cope with this life-altering condition is very inspiring. Instead of being consumed by negative feelings, they actively took charge of the huge transition in both of their lives. They both play active roles in the Alzheimer’s Association. [My buddy] spoke…on TV about the disease. But he did not attain his current optimism without struggle.”
Monthly program meetings
Students reported benefits of the monthly meetings. One student wrote: “I’ve learned so much about AD not just from my buddy but also from my fellow [program] classmates…who have shared their experiences and their reactions in our monthly meetings.” Another student wrote: “Discussing and sharing stories about our buddies…has enlightened me on how each individual with AD experiences the symptoms in unique ways and how AD affects family members in different ways.”
Program impact on clinical practice
Students reported that participation changed their future practice and improved their attitudes towards elders. A student reflected: “I learned practical skills, such as communicating with elder patients…and how to treat patients with empathy and respect. I think that PAIRS is a valuable program and has made me a better overall healthcare provider and human being.” Another student noted: "The great doctor takes the time to assess the impact on the patient’s quality of life and also treats the emotional and social ‘symptoms’ of the problem.” One student explained: “This program has given me knowledge and experience that I believe will make me a better physician regardless of the field that I go into.”
Influence on specialization
For certain students, participation either solidified an existing interest or positively influenced their opinion of geriatrics or AD-related fields they may not have previously considered. Students wrote: “I entered the program with a slight interest in neurology, but I leave it with a significant one” and “The program…has certainly made me more comfortable working with older adults.” Another student wrote:
“I certainly have a stronger interest in [the older adult] patient population as a result of the program. I used to have this perception that it would be very difficult to work with older patients, especially those with dementia, but I realize now that although it takes a bit more effort, it is more than worthwhile.”
This study quantitatively and qualitatively evaluated the PAIRS Program’s impact on first year medical student education. Results indicate quantitative improvements in dementia knowledge that are unrelated to prior professional or personal exposure to AD, offering support of the program’s first objective of increasing student knowledge about AD and related cognitive impairment. Qualitative essay results further support this finding, as students reported directly observing cognitive and behavioral symptoms, such as difficulties with memory, verbal fluency, communication skills, and inhibition. The buddy interactions were augmented by group discussion and guest lecturers during monthly meetings with program leadership and staff. Because each student formed a unique relationship with a different patient, discussion of experiences exposed students to multiple perspectives and situations not encountered with their own buddy. Students reported that the guest lecturers covering neuropathology, diagnostic advances, and emerging therapeutic targets complimented their experiential learning. Collectively, these data imply that a combination of formal and experiential education facilitated acquisition of a deeper understanding of AD.
Qualitative findings further support the program’s second objective to enhance student awareness of care and support-related issues encountered by patients and their families. By establishing a personal relationship, students were exposed to the psychosocial challenges of coping with a chronic disease that extend beyond a prescribed set of symptoms. Students reported witnessing the psychosocial and physical impact of caregiving, reflecting recognition of the disease’s impact on the entire family system. Qualitative results suggest program participation increased students’ awareness of the human side of AD and their compassion for elders experiencing dementia.
Results from the reflective essays also support the third program objective, namely enhancing students’ communication skills and patterns when interacting with older individuals. Students reported feeling more comfortable with their communication skills and more confident that their newfound understanding of AD would translate into more compassionate and considerate care of elders. Students reported improved attitudes toward older and cognitively impaired individuals and discussed the value of maintaining respect and optimism when delivering a diagnosis or recommendations. Finally, students described increased awareness of elder-centric healthcare needs and expressed increased interest in or comfort working with elders.
The fourth program objective was to introduce students to career opportunities in geriatrics and related fields. Some students reported that their buddy experiences favorably influenced or even confirmed their decision to specialize in geriatrics or neurology. Other students developed an interest in contributing to AD research, either during medical training or later in their career. Such specialization outcomes will require follow-up of the student cohort, as only 18 of the 45 student participants to date have completed the residency matching process.
Collectively, our quantitative and qualitative findings support the notion that the Buddy ProgramTM model can be successfully replicated and that this program model enhances first year medical student educational experiences. The program structure compliments a recent progression of medical curriculum toward experiential learning initiatives. Contemporary medical school curricula are dissolving traditional divisions of pre-clinical and clinical training with a trend toward early exposure to practical experience and patient populations . In fact, the Liaison Committee on Medical Education recently changed accreditation policies to incorporate service-learning, defined as a structured learning experience that combines community service with preparation and reflection. Medical schools must now provide sufficient opportunities for medical students to participate in service-learning. Our program model not only meets such service-learning criteria but can be replicated by other institutions to enhance their service-learning opportunities.
Innovative educational programs that enhance the acquisition of knowledge, skills, and positive attitudes regarding geriatric healthcare are more important than ever. As life expectancy increases, the demand for physicians qualified to handle complex geriatric healthcare will exceed physicians available . Knowledge and skills in geriatric care, regardless of specialty, is essential to providing quality, cost-effective healthcare to elders with chronic conditions, including dementia. Therefore, core medical school training would benefit from geriatric-based programs and sensitization to geriatric issues to ensure competency among future physicians caring for older adults. As an example, senior mentor programs introduce students to healthy community-based elders to help students view aging as a multidimensional process . Such programs have enhanced students’ attitudes towards elders [23, 24], improved students’ communication skills , and taught students the value of interdisciplinary care . Our findings suggest that the PAIRS Program and The Buddy ProgramTM expand the fundamentals of existing mentor programs with a unique focus on needs of older adults with cognitive impairment. Therefore, in addition to fulfilling a service-learning need, the PAIRS Program responds to the need for medical school curriculum to improve attitudes toward elders.
The present study has several strengths. Our program is the first formal replication of The Buddy ProgramTM, and our quantitative and qualitative outcomes support the reproducibility of the model for fulfilling the student training objectives put forth. Second, while experiential educational programs between students and elders currently exist, these programs emphasize healthy older adults, often screened to exclude individuals with chronic disease or cognitive impairment. The Buddy ProgramTM and PAIRS Program model is among the first to exclusively expose medical students to cognitively impaired elders and represents a unique educational initiative responding to the increased prevalence of dementia and efforts to provide medical students with service-learning opportunities. Finally, the combination of qualitative and quantitative methodology provides a comprehensive examination of program data and extends prior outcomes from The Buddy ProgramTM.
In light of our small sample size (n = 45) and the purposeful selection of our students, generalizability of our findings to a larger medical student population may be limited. Because only students interested in the program goals elected to apply and the students selected were among the more enthusiastic and committed students who interviewed, it is possible that our participants’ engagement in the program does not reflect that of the average first year medical student. It is noteworthy that comparison of our participants with applicants not selected for participation suggests comparable pre-existing exposure to and personal/familial familiarity with AD. However, it is still plausible that all applicants, whether selected or not selected for participation, are fundamentally different from their classmates who did not apply for the program. Another noteworthy limitation is that while there was a modest improvement on the pre-and post-tests of Alzheimer’s disease and dementia knowledge, the source of improvement is unknown. That is, it is unknown if enhanced knowledge over the academic year was due to the monthly student luncheons with supplemental education, monthly buddy interactions, or some combination of these curricular elements. Themes from the student’s reflective essays support the notion that a combination of the monthly luncheons and the buddy interactions enhanced student knowledge; however, future evaluation methods should attempt to better understand the most valuable element of the program in enhancing student knowledge.
Future directions include continued assessment of the PAIRS Program and expansion of existing evaluation methods. We will continue to track the residency selections for program alumnae with each class of graduating students. In program year 5, we introduced quantitative assessment of changes in students’ attitudes, stigma, and empathy via survey tools pre- and post-program participation. These measures are designed to more comprehensively monitor the development of key elements of humanism in medicine. Research is also needed to evaluate prospective replication of the program model among other student cohorts, such as nurses, social workers, and undergraduate students. Finally, evaluation methods could be enhanced by addition of buddy and care partner feedback.
This study evaluated the PAIRS Program and its effectiveness in enhancing medical education as a service-learning. Quantitative and qualitative analyses of data from the first four program years show post-program improvements aligned with the program objectives. Performance on knowledge tests and themes extracted from students’ reflective essays demonstrate an increase in dementia knowledge, appreciation for the psychosocial and support-related challenges faced by patients and families, enhanced communication skills, and exposure to dementia-related fields of medicine and research following completion of the program. Our findings suggest the PAIRS Program can successfully fulfill the need for service learning opportunities while improving positive attitudes regarding the healthcare of older or cognitively impaired adults. Increased interest in geriatric healthcare is more important than ever in light of the growing needs of our rapidly aging population. Moreover, our study supports the ability to successfully replicate The Buddy ProgramTM model and encourages additional institutions to implement similar programs to enrich students’ medical education.
