Preparing medical students to care for older adults: the impact of a Senior Mentor Program.

PURPOSE: To provide alternative training experiences for medical students to improve the competencies needed to provide care for older adults. METHOD: Part of a comprehensive approach to integrating geriatric content at the University of South Carolina (USC) School of Medicine, the Senior Mentor Program (SMP) was launched in 2000. The SMP links pairs of students with older community volunteers in the spring of the first year. Students visit their mentors throughout medical school, and execute assignments that complement materials covered in the traditional curriculum. To evaluate the feasibility and efficacy of the SMP, the authors describe the program's operation and outputs, the extent to which undergraduate medical education at USC and the SMP meet the core competencies for care of older adults promulgated by the American Geriatrics Society (AGS), and analyze the coverage of geriatrics content from 2000 to 2005 at USC, as indicated by responses to the Medical School Graduation Questionnaire. RESULTS: From 2000 to 2005, 379 students enrolled in the SMP; 133 graduates of the classes of 2004 and 2005 have completed the SMP. Students and mentors indicated high acceptance and enthusiasm. The program has been maintained with minimal administrative burden. USC covered only half of AGS competencies before the SMP, but now covers 100%, with nearly a third met specifically through the SMP. USC graduates reporting inclusion of geriatrics throughout their four years of training rose from 66% in 2002 to 96% in 2004-05. CONCLUSIONS: The SMP has had a substantial impact on students' preparation for dealing with an aging patient population.

Cross-sectional and longitudinal association between antihypertensive medications and cognitive impairment in an elderly population.

BACKGROUND: The effect of antihypertensive medications on cognitive function has not been well studied. The authors' objectives were to investigate the cross-sectional and longitudinal association between the use of antihypertensive medications and cognitive function and to compare different antihypertensive medication classes with regard to this association in an elderly population. METHODS: The medical records of a convenience sample of patients (n = 993 cross-sectional and 350 longitudinal; mean age, 76.8 +/- 0.3 years; 74% women; 87% White) followed at a geriatric practice were reviewed. Data abstracted included demographics, medical history (Alzheimer's disease [AD] or vascular dementia [VaD]), use of antihypertensive medications, and results of cognitive assessments (the Mini-Mental Status Examination [MMSE] and the Clock Draw Test [CDT]). RESULTS: In the cross-sectional analysis, antihypertensive use was not associated with MMSE (p >.05), CDT (p >.05), or dementia diagnosis (odds ratio for AD, 0.8; 95% confidence interval [CI], 0.6 to 1.2; odds ratio for VaD, 1.6; 95% CI, 0.6 to 4.0). In the longitudinal analysis, antihypertensive use was associated with a lower rate of cognitive decline on the MMSE (-0.8 +/- 2 points in users vs -5.8 +/- 2.5 points in nonusers; p =.007) and on the CDT (-0.3 +/- 0.8 points in users vs -2.2 +/- 0.8 points in nonusers; p =.002), and with a lower risk for the development of cognitive impairment (odds ratio, 0.56; 95% CI, 0.38 to 0.83; p =.004). The trend was similar in patients with baseline AD (p =.02). Patients taking diuretics (p =.007), angiotensin-converting enzyme inhibitors (p =.016), and beta-blockers (p =.014) had a lower rate of cognitive decline, and patients taking angiotensin receptor blockers (p =.016) had improved cognitive scores. CONCLUSIONS: Antihypertensive use, particularly diuretics, angiotensin-converting enzymes inhibitors, beta-blockers, and angiotensin receptor blockers, may be associated with a lower rate of cognitive decline in older adults, including those with AD. Until a randomized clinical trial confirms our results, findings of this observational study should be interpreted with caution.

Geriatric content in medical school curricula: results of a national survey.

Despite recent gains in establishing academic sections, divisions, and departments of geriatrics in medical schools, much remains to be done to meet the medical needs of an aging population. To better understand how medical schools are educating students in geriatric-related topics, all U.S. allopathic and osteopathic medical schools were surveyed in two waves, in 1999 and 2000, using a questionnaire based on recommendations from the Education Committee of the American Geriatrics Society. Responding schools were more likely to address diseases and conditions of aging, psychosocial issues, and ethical issues and less likely to cover anatomic changes, nutrition, knowledge of healthcare financing, outcome measurement, and cultural aspects of aging. Although limited, the results indicate that medical schools have increased coverage of aging-related material, although further expansion of geriatric content will be necessary to meet the needs of an aging society.

Geriatrics training and education for nongeriatrician faculty: the Dean's Faculty Scholars in Aging Program.

The University of South Carolina School of Medicine in Columbia implemented the Dean's Faculty Scholars in Aging (DFSA) Program in 2001 to strengthen the knowledge of geriatrics of nongeriatrician faculty members. The primary indicator of strengthening physicians' geriatrics knowledge was the development of new educational experiences by physicians in the DFSA Program. Twenty-six nongeriatrician faculty in seven departments were recruited to participate as scholars. Most scholars were in key educational positions, including assistant deans, department chairs, and clerkship and residency directors. Scholars received special training to develop geriatrics educational experiences based on their medical specialty and interests. Training encouraged cross-departmental collaboration. Scholars also had access to resources, including professional geriatric educators. Funds were available to support development of educational experiences and for a small amount of salary support. Since the program was implemented, 36 new geriatric experiences have been developed, 29 of the 36 were implemented, and 11 of the 36 were evaluated. Experiences included an elective for residents in the care of older patients in the emergency room and a required hospice rotation in the psychiatry clerkship for third-year medical students. All scholars developed a geriatrics educational experience, and most implemented one. This suggests that scholars demonstrated successful progress in geriatrics training.

Use of a questionnaire to screen for frailty in the elderly: an exploratory study.

BACKGROUND AND AIMS: In a pilot study of community-dwelling geriatric clinic patients (N=48, aged 63-90) we examined the use of a questionnaire to classify frailty status by comparing it with standardized markers of frailty. The questionnaire, developed by Strawbridge et al. in 1998, defines frailty as difficulty in more than one of four domains of functioning: physical, cognitive, sensory, and nutritive. METHODS: Subjects were classified as frail or not frail by questionnaire and assignment was compared with testing of physical and cognitive measures in cross-sectional analysis. Demographic variables, functional inventories, physical activity levels, clinician impression of frailty, and 3-year health outcomes were also examined. RESULTS: Thirty-three percent of subjects were classified as frail. Frailty classification by the Strawbridge questionnaire was correlated to Timed Up and Go and repetitive Sit-to-Stand tests, bimanual dexterity and cognitive tests. A discrepancy was found between assignment of cognitive difficulty, by questionnaire and cognitive performance. When overall Strawbridge frailty scores were modified to account for those with poor cognitive performance who did not report cognitive difficulty, the prevalence of frailty increased to 42%. At 3-year follow-up, the modified Strawbridge frailty classification (p<0.05) and clinician impression of frailty (p<0.01) were both significant predictors of death and institutionalization combined. CONCLUSIONS: This study serves as an initial inquiry into the potential validity and utility of the Strawbridge frailty questionnaire as a simple screening tool to identify patients who may warrant detailed functional testing.

Assessing geriatrics in undergraduate medical education: two different approaches.

Most medical schools do not have a separate course in geriatrics, but rather incorporate geriatrics into existing courses. Tracking and assessing curriculum content is more difficult in this setting. This paper describes and compares two approaches to assess curriculum content in geriatrics: a survey of course directors and a course objectives review. The results suggest that course directors report more geriatric content when asked as part of a regular survey than they identify as specific course objectives. Course objectives may be more reflective of the actual emphasis placed on aging-related material in courses. These two approaches appear to be complementary. Medical educators may find both self-report and course objective analysis to be useful and complementary in tracking geriatric material in the undergraduate medical curriculum.

The effectiveness and costs of comprehensive geriatric evaluation and management.

Comprehensive geriatric assessment (CGA) is a multidimensional interdisciplinary diagnostic process focused on determining a frail elderly person's medical, psychological, and functional capabilities in order to develop a coordinated and integrated plan for treatment and long-term follow-up. Geriatrics interventions building on CGA are defined from their historical emergence to the present day in a discussion of their complexity, goals and normative components. Through literature review, questions of the effectiveness and costs of these interventions are addressed. Evidence of effectiveness is derived from individual trials and, particularly, recent systematic reviews. While the trial evidence lends support to the proposition that geriatric interventions can be effective, the results have not been uniform. Review of meta-regression studies suggests that much of this outcome variability is related to identifiable program design parameters. In particular, targeting the frail, an interdisciplinary team structure with clinical control of care, and long-term follow-up, tend to be associated with effective programs. Answers to cost-effectiveness questions also vary and are more rare. With some exceptions, existing evidence as exists suggest that geriatrics interventions can be effective without raising total costs of care. Despite the attention given to these questions in recent years, there is still much room for clinical and scientific advance as we move to better understand what CGA interventions do well and in whom.

The impact of the use of statins on the prevalence of dementia and the progression of cognitive impairment.

BACKGROUND: Previous evidence suggests that treatment with 3-hydroxy-3-methylglutaryl-coenzyme-A reductase inhibitors (statins) has a positive impact on dementia. We decided to investigate the association between the use of statins and the prevalence of dementia and statins' impact on the progression of cognitive impairment. METHODS: This is a case-control and a retrospective cohort study of a community-based ambulatory primary care geriatric practice. We included a convenience sample of all patients (N = 655, mean age 78.7 +/- 0.3 years, 85% Caucasian, 74% women) with hypercholesterolemia or dementia, or using statins. We compared those using statins with those who do not with respect to the clinical diagnosis of dementia and its subtypes and the progression of cognitive impairment. RESULTS: At the initial visit, 35% had dementia, and 17% were using statins. After covariate adjustments, patients on statins were less likely to have dementia (odds ratio [OR] for dementia based on composite definition = 0.23; 95% confidence interval [CI] [0.1-0.56], p =.001, OR Alzheimer's disease = 0.37; 95% CI [0.19-0.74], p =.005, OR vascular dementia = 0.25; 95% CI [0.08-0.85], p =.027). At follow-up, patients on statins showed an improvement on their Mini-Mental Status Examination score by 0.7 +/- 0.4 compared to a decline by 0.5 +/- 0.3 in controls, p =.025 (OR for no change or improvement on statins = 2.81; 95% CI [1.02-8.43], p =.045) and scored higher on the Clock Drawing Test (difference of 1.5 +/- 0.1, p =.036). CONCLUSIONS: The use of statins is associated with a lower prevalence of dementia and has a positive impact on the progression of cognitive impairment.

Coordination and advocacy for rural elders (CARE): a model of rural case management with veterans.

PURPOSE: To describe a pilot initiative sponsored by the Veterans Health Administration (VHA) to improve the health and community tenure of frail older veterans living in rural counties 50-100 miles from two host VHA medical centers. DESIGN AND METHODS: Veterans aged 75 and older who scored at risk of repeated hospital admission on the PRA-Plus telephone questionnaire were targeted and visited by evaluators who administered a comprehensive health questionnaire prior to being assessed at home by the Coordination and Advocacy for Rural Elders (CARE) program clinical teams. Guided by current state-of-the-art practices, the nurse-social worker teams performed in-home standardized assessments using the MDS-HC, developed patient-specific care plans, and mobilized family, community, and VHA resources to implement plans. RESULTS: On average, eight problems were identified for each patient, most commonly falls risk, social needs, pain, and needs related to IADL disability. As a result of initial assessment, two thirds of CARE participants received referral/linkage to formal services, more than half to medical providers. IMPLICATIONS: Through CARE, the VHA is learning more about the unmet needs of older rural veterans. Further development and evaluation should guide the VHA toward providing efficient, effective community-based services to all frail older veterans.

Comprehensive geriatric assessment.

BACKGROUND: As an adjunct to the general and cancer-specific clinical and diagnostic examinations, comprehensive geriatric assessment (CGA) is an integral tool that examines factors affecting the course of disease and the outcome of treatment. The principal areas of focus of the CGA include the patient's functional, physical, mental, emotional, pharmacotherapeutic, and socioeconomic status. METHODS: We describe the role of CGA in the identification and management of frail elderly patients. The literature is reviewed to outline the components, programmatic configurations, and process of CGA. Information from systematic reviews of clinical trials of different CGA program models is summarized, and observations relating to the research agenda concerning the applicability of CGA and CGA principles to management of older cancer patients are discussed. RESULTS: Since age itself is not predictive of outcome in an elderly cancer patient, the CGA helps to distinguish between elderly patients who should be treated with intent to cure and those who will benefit from clinical oncologic and geriatric co-management. CONCLUSIONS: A more accurate evaluation of prognostic indicators that includes CGA parameters could lead to a higher number of older patients being included in clinical cancer trials and being treated effectively in practice. It would also identify those who would benefit from gero-oncologic CGA and ongoing management aimed at maintaining function and community living.
