The cross-sectional association of frailty with past and current exposure to strong anticholinergic drugs

BACKGROUND

Anticholinergic drugs may contribute to frailty by impairing cognitive and physical functions. Strong anticholinergic drugs in particular may have adverse effects among older adults.

OBJECTIVES

Determine the association between frailty and the use of strong anticholinergic drugs among older US Veterans.

METHODS

This is a cross-sectional study of community-dwelling Veterans 65 years and older who had determinations of frailty status. Prescription data for patients using strong anticholinergic medications (never/past/current) was obtained via electronic health records. A 31-item VA Frailty Index (VA-FI) was generated at the time of the assessment. We dichotomized the groups into non-frail (FI =  < 0.21) and frail (FI ≥ 0.21) patients. We used binomial logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Frailty was the dependent variable and use of strong anticholinergic drugs was the independent variable. Multivariate adjustment was conducted for age, gender, race, ethnicity, marital status, and BMI.

RESULTS

Population sample consisted of 17,084 Veterans who were 71.05% Caucasian, 97.34% male, and with a mean age 75.60 (SD = 8.04) years. Among the population, 9940 (58.18%) patients had no previous use of strong anticholinergic drugs, whereas 5182 (30.33%) had past exposure and 1962 (11.49%) had current exposure. In binomial logistic regression, individuals with past (OR 3.27, 95% CI 3.03-3.54, p < 0.0005) or current (OR 4.78, 95% CI 4.30-5.31, p < 0.0005) exposure showed a higher association with frailty as compared to individuals who were never exposed.

CONCLUSIONS

Past and current use of strong anticholinergic drugs were associated with frailty in older Veterans. These results suggest that screening for frailty in patients with past or current exposure to strong anticholinergic medications may be necessary for proper management.

Depression but not frailty contributed to a higher risk for all-cause hospitalizations in male older veterans

INTRODUCTION

Frailty is a state of vulnerability to stressors resulting in higher morbidity, mortality, and utilization in older adults. Depression and frailty often coexist, suggesting a bidirectional relationship that may increase the effects of each individual condition on clinical outcomes and health-care utilization in older adults.

OBJECTIVE

To determine the effects of concurrent frailty and depression on all-cause hospitalizations.

METHODS/DESIGN

Prospective cohort study, conducted at a Veterans Affairs (VA) Medical Center. The participants were male, community-dwelling veterans 65 years and older. From 4 January through 30 December 2016, a 46-item frailty index was generated from data obtained from the VA electronic health record. Trained staff conducted in-depth reviews of electronic health records ascertaining depression status. Patients were followed through 31 December 2017 for all-cause hospitalizations following the initial assessment of frailty. After adjusting for covariates, the association of frailty and depression with all-cause hospitalizations was determined with the Andersen-Gill model, accounting for repeated hospitalizations.

RESULTS

Five hundred fifty-three male patients were part of the study, mean age 76.3 (SD = 8.2) years. One hundred eighty-one patients (32.7%) had depression diagnoses. During a median follow-up period of 530 days (interquartile range [IQR] = 245), 123 patients (22.2%) had 240 hospitalizations. Frailty status was not associated with future hospitalizations (adjusted hazard ratio [HR] = 1.61; 95% CI, 95-2.74; P > .05). Depression was associated with higher all-cause hospitalizations (adjusted HR = 1.57; 95% CI, 1.09-2.26); P = .0157).

CONCLUSIONS

Depression but not frailty was significantly associated with higher rates of all-cause hospitalization. Implementing interventions that target older adults with both frailty and depression may reduce the burden of both conditions and reduce hospitalizations.

The Association of Ageist Attitudes With All-Cause Hospitalizations and Mortality

Background: Ageism is the systematic stereotyping and discrimination against older adults. Explicit ageism involves conscious control and implicit ageism involves unconscious processes. Studies have shown that ageist attitudes may be associated with poor clinical outcomes like hospitalizations and mortality. Objective: Determine the association of explicit and implicit ageism with all-cause hospitalizations and mortality in a sample of Veterans. Method: Retrospective cohort study of community-dwelling Veterans 50 years and older who underwent evaluations of explicit ageism using Kogan’s Attitudes Toward Old People Scale and implicit ageism assessed with Implicit Association Test (IAT) during July 2014 to April 2015 and were followed until 2018. Data on all-cause hospitalizations and mortality following the initial assessment of ageism was aggregated. Results: The study included 381 participants, 89.8% male, 48.0% White, and mean age was 60.5 (SD = 7.2) years. A total of 339 completed the IAT. Over a mean follow-up of 3.2 years (SD = 0.3), 581 hospitalizations, and 35 deaths occurred. Neither explicit nor implicit ageism was associated with an increased risk for all-cause hospitalization or mortality on follow-up. Discussion: Future research may benefit from investigating whether ageist attitudes may predict all-cause hospitalizations and mortality in longitudinal studies including more diverse samples.

Is there an association between ageist attitudes and frailty?

BACKGROUND

Frailty is defined as a state of vulnerability to stressors that is associated with higher morbidity, mortality and healthcare utilization in older adults. Ageism is "a process of systematic stereotyping and discrimination against people because they are old." Explicit biases involve deliberate or conscious controls, while implicit bias involve unconscious processes. Multiple studies show that self-directed ageism is a risk factor for increased morbidity and mortality. The purpose of this study was to determine whether explicit ageist attitudes are associated with frailty in Veterans.

METHODS

This is a cross-sectional study of Veterans 50 years and older who completed the Kogan's Attitudes towards Older People Scale (KAOP) scale to assess explicit ageist attitudes and the Implicit Association Test (IAT) to evaluate implicit ageist attitudes from July 2014 through April 2015. We constructed a frailty index (FI) of 44 variables (demographics, comorbidities, number of medications, laboratory tests, and activities of daily living) that was retrospectively applied to the time of completion of the KAOP and IAT. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by multinomial logistic regression models with frailty status (robust, prefrail and frail) as the outcome variable, and with KAOP and IAT scores as the independent variables. Age, race, ethnicity, median household income and comorbidities were considered as covariates.

RESULTS

Patients were 89.76% male, 48.03% White, 87.93% non-Hispanic and the mean age was 60.51 (SD = 7.16) years. The proportion of robust, pre-frail and frail patients was 11.02% (n = 42), 59.58% (n = 227) and 29.40% (n = 112) respectively. The KAOP was completed by 381 and the IAT by 339 participants. In multinomial logistic regression, neither explicit ageist attitudes (KAOP scale score) nor implicit ageist attitudes (IAT) were associated with frailty in community dwelling Veterans after adjusting for covariates: OR = .98 (95% CI = .95-1.01), p = .221, and OR:=.97 (95% CI = .37-2.53), p = .950 respectively.

CONCLUSIONS

This study shows that neither explicit nor implicit ageist attitudes were associated with frailty in community dwelling Veterans. Further longitudinal and larger studies with more diverse samples and measured with other ageism scales should evaluate the independent contribution of ageist attitudes to frailty in older adults.

Association of the CAN score with the FRAIL scale in community dwelling older adults

BACKGROUND

Frailty is a state of vulnerability to stressors which results in higher morbidity, mortality and healthcare utilization. The FRAIL scale is used as a validated screening for frailty. The Care Assessment Need (CAN) score is automatically generated from electronic health record data using a statistical model that includes data elements similar to the deficit accumulation model for frailty and predicts risk for hospitalization and/or mortality.

AIM

To determine the correlation of the CAN score with the FRAIL scale.

METHODS

A cross-sectional study of 503 community-dwelling older adults. We compared the FRAIL scale with the CAN score.

RESULTS

The CAN score was significantly different between robust, prefrail and frail. Post hoc analysis revealed significant increases in scores from robust to prefrail and frail groups, in that order. The CAN score and FRAIL scale showed a correlation.

CONCLUSIONS

The CAN score show a moderate positive association with the FRAIL scale.

Validation of an automatically generated screening score for frailty: the care assessment need (CAN) score

BACKGROUND

Frailty is a state of vulnerability to stressors that is prevalent in older adults and is associated with higher morbidity, mortality and healthcare utilization. Multiple instruments are used to measure frailty; most are time-consuming. The Care Assessment Need (CAN) score is automatically generated from electronic health record data using a statistical model. The methodology for calculation of the CAN score is consistent with the deficit accumulation model of frailty. At a 95 percentile, the CAN score is a predictor of hospitalization and mortality in Veteran populations. The purpose of this study was to validate the CAN score as a screening tool for frailty in primary care.

METHODS

This is a cross-sectional, validation study compared the CAN score with a 40-item Frailty Index reference standard based on a comprehensive geriatric assessment. We included community-dwelling male patients over age 65 from an outpatient geriatric medicine clinic. We calculated the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of the CAN score.

RESULTS

184 patients over age 65 were included in the study: 97.3% male, 64.2% White, 80.9% non-Hispanic. The CGA-based Frailty Index defined 14.1% as robust, 53.3% as prefrail and 32.6% as frail. For the frail, statistical analysis demonstrated that a CAN score of 55 provides sensitivity, specificity, PPV and NPV of 91.67, 40.32, 42.64 and 90.91% respectively whereas at a score of 95 the sensitivity, specificity, PPV and NPV were 43.33, 88.81, 63.41, 77.78% respectively. Area under the receiver operating characteristics curve was 0.736 (95% CI = .661-.811).

CONCLUSION

CAN score is a potential screening tool for frailty among older adults; it is generated automatically and provides acceptable diagnostic accuracy. Hence, the CAN score may be a useful tool to primary care providers for detection of frailty in their patient panels.

Dramatic Reduction in 30-Day Readmissions Through High-Risk Screening and Two-Phase Interdisciplinary Care

OBJECTIVES

Thirty-day readmissions are common, serious, and costly. Most important, often they are preventable. The purpose of this quality improvement study was to evaluate an interdisciplinary, two-phase intervention to reduce 30-day readmissions among high-risk medical patients. One or two high-risk patients were selected each weekday by a hospitalist using literature-based, locally tested criteria that included common medical illnesses, active psychiatric illness, and recent or recurrent hospital admissions.

METHODS

Patients admitted to 1 of 5 medical hospitalist teams were selected to receive the intervention; patients admitted to the 4 remaining teams were used for comparison. The two-phase care coordination intervention consisted of a daily interdisciplinary team meeting for the selected high-risk patients and postdischarge interventions that included outpatient care coordination until the patients' first follow-up appointment. The care plan addressed medical/geriatric assessment, social stability, medication reconciliation, nutritional needs, care coordination including future appointments/testing, and community services. Eighty-five patients in the intervention group were compared with 84 patients from the comparison group using propensity score matching. Patient characteristics were similar at baseline.

RESULTS

The intervention group demonstrated a reduction in 30-day readmissions by 52% (11 vs 23, P = 0.019). Length of stay was reduced: 5.5 days compared with 7.2 days (P = 0.258).

CONCLUSIONS

This intervention produced a significant reduction in 30-day readmissions for high-risk patients and a trend for shorter lengths of stay compared with similarly matched patients. Future research trials are needed to verify these results.

Group-based differences in anti-aging bias among medical students

Medical students (MS) may develop ageist attitudes early in their training that may predict their future avoidance of caring for the elderly. This study sought to determine MS' patterns of explicit and implicit anti-aging bias, intent to practice with older people and using the quad model, the role of gender, race, and motivation-based differences. One hundred and three MS completed an online survey that included explicit and implicit measures. Explicit measures revealed a moderately positive perception of older people. Female medical students and those high in internal motivation showed lower anti-aging bias, and both were more likely to intend to practice with older people. Although the implicit measure revealed more negativity toward the elderly than the explicit measures, there were no group differences. However, using the quad model the authors identified gender, race, and motivation-based differences in controlled and automatic processes involved in anti-aging bias.

Effects on performance of individual versus dyadic practice during an avatar-based three-dimensional virtual home safety simulation

This pilot study tests the effects on individual performance of dyadic versus individual practice in a 3D virtual world (VW) home safety assessment. Sixty medical students in three conditions (dyadic spatially separated with paired avatars DPA; individual with avatar IND; and dyadic spatially together with single avatar DSA) participated in a geriatric home safety simulation. The participants, via avatars, conducted an assessment of physical hazards. Participants then worked individually in a separate 3D VW home assessment. Dyadic practice, spatially together with a single avatar (DSA), improved individual performance in the subsequent 3D VW home assessment.

Medical students' attitudes toward obese patient avatars of different skin color

Physicians' biases for skin color and obesity may negatively affect health-care outcomes. Identification of these biases is the first step to address the problem. We randomized 128 U.S medical students into one of four animated videos of avatar physician-patient counseling sessions, varying the weight and skin color of an elderly patient avatar: white-thin, black-thin, white-obese and black-obese. Medical students viewed white obese avatars as unattractive, ugly, noncompliant, lazy, and sloppy. Medical students' comments suggested a paternalistic attitude toward avatar patients. Avatar-mediated experiences can elicit medical students' bias potentially enabling medical educators to implement bias reduction interventions.

Simulating geriatric home safety assessments in a three-dimensional virtual world

Virtual worlds could offer inexpensive and safe three-dimensional environments in which medical trainees can learn to identify home safety hazards. Our aim was to evaluate the feasibility, usability, and acceptability of virtual worlds for geriatric home safety assessments and to correlate performance efficiency in hazard identification with spatial ability, self-efficacy, cognitive load, and presence. In this study, 30 medical trainees found the home safety simulation easy to use, and their self-efficacy was improved. Men performed better than women in hazard identification. Presence and spatial ability were correlated significantly with performance. Educators should consider spatial ability and gender differences when implementing virtual world training for geriatric home safety assessments.

Hispanic ethnicity and unintentional injury mortality in the elderly

BACKGROUND

Unintentional injury is a leading cause of preventable mortality in elderly populations and is most often related to accidental falls and motor vehicle accidents. Hispanic ethnicity has been previously associated with decreased risk of accidental fall death as well as improved outcomes in other health states, the "Hispanic paradox." A timely analysis of national data with consideration for multiple injury types and age could provide insight into this epidemiologic phenomenon and help guide the use of prevention efforts.

MATERIALS AND METHODS

Search of the Center for Disease Control's WISQARS database was performed to identify the number of fatalities in the U.S. between 2003 and 2006 by age group, gender, Hispanic ethnicity, and injury type. Total U.S. population and group populations for the years examined were obtained from the U.S. Census Bureau's American Community Survey for each year. Mortality was calculated as fatalities over the total group population for the years examined.

RESULTS

Independent of gender and age group, elderly Hispanics were at decreased risk of death from accidental fall or as an occupant in a motor vehicle accident, but increased risk of pedestrian fatality compared with white-NH.

CONCLUSIONS

The reduced fall and occupant mortality seen in elderly Hispanic populations may come at the cost of increased pedestrian-related mortality. This is consistent with and likely reflects differences in culture, socioeconomic status, and geographic distribution for the U.S. Hispanic population. Effective targeting of injury prevention programs, especially community based, should consider the role of Hispanic ethnicity and its impact on lifestyle.

A fourth-year medical school clerkship that addressed negative attitudes toward geriatric medicine

Despite extensive educational efforts, many medical students still have negative attitudes toward the field of geriatric medicine and the care of older adult patients. This article describes a fourth-year geriatric clerkship that addressed this issue by providing opportunities for students to actively discuss many of the negative stereotypes that exist regarding geriatric medicine. Emphasis was also placed on personalizing the course content to show the relevance of geriatric medicine to all medical students. During the 2008/09 academic year, 150 students completed the rotation. Although no students expressed an interest in pursuing a career as a geriatrician, they expressed a highly favorable evaluation of this personalized geriatric clerkship and voted this clerkship "the most outstanding clinical course" at the medical school.

Trial of a survey instrument to establish the hurricane preparedness of and medical impact on a vulnerable, older population

INTRODUCTION

Millions of vulnerable, elderly individuals live in coastal areas susceptible to hurricanes and are at risk for adverse health outcomes. The purpose of this study was to determine the status of preparedness for and possible health consequences of a hurricane on a vulnerable, but experienced, elderly population.

PROBLEM

Preparedness guidelines have been published, but it is unclear how well-prepared elderly individuals are for hurricanes, and what impact hurricanes may have on their health.

METHODS

Five hundred forty-seven ambulatory patients who attended an urban teaching hospital's geriatrics clinic in Florida were surveyed. A 25-question survey that asked whether subjects followed the American Red Cross guidelines for hurricane preparation was developed. The participants were asked what hurricane supplies they had, and whether they would need to evacuate or utilize storm-proof window shutters. They also were queried about definitions and their understanding of hurricane warnings. Three possible health impacts during the two weeks following Hurricane Wilma in 2005 were asked: (1) falls; (2) missed medication; and (3) missed doctor's appointments. An additional 105 patients in the same clinic were asked about the same three health outcomes one and one-half years after the hurricane struck.

RESULTS

Two-thirds of respondents were missing at least one supply item. A multivariate analysis indicated that there was no relationship between the subjects' demographic characteristics and the possession of the suggested disaster supplies. Although 36% would need to evacuate, only 56% of these 36% had a plan. Only 63% had storm-proof windows or shutters, and of these, only 46% could install them. Gasoline-powered electrical generators can be useful, but also a source of morbidity or mortality following a hurricane. For example, this study found that 28% of respondents had generators, but only 46% knew how to use them. Subjects immediately after the hurricane missed fewer doses of medication than at other times (3.4% vs. 6.7%; p < 0.0001) and fell slightly less often (8.8% vs. 12.9%; p < 0.0001). However, there were significantly more missed doctors appointments after the hurricane (11.6% vs. 0.1%, p < 0.0001).

CONCLUSIONS

The survey indicated that even a well-experienced population lacks adequate hurricane preparation. Most still are vulnerable in at least one aspect of preparation. The elderly may be more likely to miss medical appointments immediately following a hurricane. Interventions to improve hurricane preparedness should be piloted.

Computer-based animations and static graphics as medical student aids in learning home safety assessment: a randomized controlled trial

BACKGROUND

Although animations may intuitively seem more effective than static graphics for teaching, there is no clear-cut evidence for the superiority of simple computer-based animations in medical education.

AIMS

We investigated whether simple animations are better than static graphics as an aid to medical students in learning home safety assessment, an important part of geriatric curriculum.

METHODS

We used two versions of an interactive online module, one that depicted common home safety issues in static graphics and the other in animations. We randomized first-year medical students who agreed to participate into two groups. After the module, students completed a cognitive burden scale and a standardized competency assessment test in which they had to identify the salient home safety issues and give recommendations based on the hazards. We also captured time spent on task.

RESULTS AND CONCLUSIONS

We found no significant differences between the groups in the cognitive burden level, competency assessment scores, and time spent on task. The much cheaper-to-produce static graphics were equally effective as simple animations in this medical education scenario.

A competency-based medical student curriculum targeting key geriatric syndromes

The University of Miami Miller School of Medicine (UMMSM) has developed and implemented a competency-based undergraduate medical education (UME) curriculum that targets 61 learning objectives for three geriatric syndromes: dementia, falls, and delirium. This curriculum redesign changed the educational focus from what is taught to what is learned. Students complete 13 different competency assessments throughout their four years of training and are required to meet specific performance standards. Documentation of competency is now provided for 600 students annually. This paper describes the design, development, implementation, and evaluation of this curriculum, reviews our data-driven curriculum quality improvement efforts, and discusses the challenges to translating student competency into routine practice.

The Consortium of E-Learning in Geriatrics Instruction

This paper describes the activities of the Consortium of E-Learning in Geriatrics Instruction (CELGI), a group dedicated to creating, using, and evaluating e-learning to enhance geriatrics education. E-learning provides a relatively new approach to addressing geriatrics educators' concerns, such as the shortage of professionals trained to care for older people, overcrowded medical curricula, the move to transfer teaching venues to community settings, and the switch to competency-based education models. However, this innovative education technology is facing a number of challenges as its use and influence grow, including proof of effectiveness and efficiency. CELGI was created in response to these challenges, with the goal of facilitating the development and portability of e-learning materials for geriatrics educators. Members represent medical and nursing schools, the Department of Veterans Affairs healthcare system, long-term care facilities, and other institutions that rely on continuing streams of quality health education. CELGI concentrates on providing a coordinated approach to formulating and adapting specifications, standards, and guidelines; developing education and training in e-learning competencies; developing e-learning products; evaluating the effect of e-learning materials; and disseminating these materials. The vision of consortium members is that e-learning for geriatric education will become the benchmark for valid and successful e-learning throughout medical education.

An interactive e-learning tutorial for medical students on how to conduct the performance-oriented mobility assessment

We evaluated the effectiveness of an e-learning tutorial (iPOMA) as a supplement to traditional teaching of the Performance-Oriented Mobility Assessment. Second-year medical students (137) completed the iPOMA, in preparation for a session on fall risk assessment consisting of a lecture, practice with elder volunteers and small group debriefing. Before and after the tutorial, students completed online questionnaires, a quiz on POMA scoring immediately after the tutorial and competency assessments on POMA performance 1 month later. Self-efficacy in using the POMA increased and post-tutorial quiz scores were significantly correlated with self-efficacy. Students who completed the tutorial performed significantly better on the verbal instructions portion of the POMA. The iPOMA is an effective instructional modality.

The use of the internet in geriatrics education: results of a national survey of medical geriatrics academic programs

In order to characterize use of the Internet in medical geriatrics education programs, 130 medical education programs in the U.S. that train medical students, interns, residents, fellows and practicing physicians were asked to complete a survey developed by the Consortium of E-Learning in Geriatrics Instruction (CELGI). Sixty-eight programs (52.3%) returned surveys. Fifty-four (79%) of those responding reported using the Internet specifically for geriatric medical education, and 38 (56%) reported they are developing Internet materials. Twentythree undergraduate, 31 graduate, and 26 continuing medical education programs reported at least 25% of their curriculum was Internet-based. Users and developers of medical geriatric Internet materials had more full-time faculty and nonclinical faculty. The results of our survey indicate that the Internet is being widely used in medical geriatric education.

Learning objects in medical education

A learning object (LO) is a grouping of instructional materials structured to meet a specified educational objective. Digital LOs, which can be stored electronically, allow a new approach to instructional activity, making medical education more efficient, and potentially more cost-effective. They are reusable and can incorporate text, graphics, animations, audio, and video to support and enhance learning. A learning object can stand alone or be aggregated with additional objects to create larger forms of educational content meeting multiple educational objectives. Digital learning objects located in online repositories can be accessed by many computers and are easily handled by an array of learning management systems for delivery to learners at any time. Integrating digital learning objects with traditional educational methods in a blended learning approach assists medical educators in meeting the challenges of competing priorities. Multimedia LOs enable learners to tailor their experience to their preferred learning style. Through the use of learning objects, learners' reactions, their acquisition of knowledge, skills and attitudes, and their behavioral changes become readily measurable. Learning objects provide multiple research opportunities, such as their use in adaptive learning, their added value in preclinical versus clinical education, and their impact as part of a blended learning strategy.

The impact of E-learning in medical education

The authors provide an introduction to e-learning and its role in medical education by outlining key terms, the components of e-learning, the evidence for its effectiveness, faculty development needs for implementation, evaluation strategies for e-learning and its technology, and how e-learning might be considered evidence of academic scholarship. E-learning is the use of Internet technologies to enhance knowledge and performance. E-learning technologies offer learners control over content, learning sequence, pace of learning, time, and often media, allowing them to tailor their experiences to meet their personal learning objectives. In diverse medical education contexts, e-learning appears to be at least as effective as traditional instructor-led methods such as lectures. Students do not see e-learning as replacing traditional instructor-led training but as a complement to it, forming part of a blended-learning strategy. A developing infrastructure to support e-learning within medical education includes repositories, or digital libraries, to manage access to e-learning materials, consensus on technical standardization, and methods for peer review of these resources. E-learning presents numerous research opportunities for faculty, along with continuing challenges for documenting scholarship. Innovations in e-learning technologies point toward a revolution in education, allowing learning to be individualized (adaptive learning), enhancing learners' interactions with others (collaborative learning), and transforming the role of the teacher. The integration of e-learning into medical education can catalyze the shift toward applying adult learning theory, where educators will no longer serve mainly as the distributors of content, but will become more involved as facilitators of learning and assessors of competency.

The educational impact of a computer-based training tutorial on dementia in long term care for licensed practice nursing students

The purpose of this study was to examine whether training with a multimedia tutorial would have an impact on LPN students' knowledge of dementia care, attitudes toward dementia care, and self-efficacy ratings. A total of 38 nursing students participated. Pre-post comparisons of outcome measures revealed significant improvements in knowledge, attitudes, and self-efficacy ratings. Results of post-training satisfaction and usability questionnaires indicate that participants found the tutorials easy to understand and easy to use. These data support the effectiveness of the dementia tutorial and the use of computer-based training in educating our long-term care workforce.

Music therapy increases serum melatonin levels in patients with Alzheimer's disease

CONTEXT

Music therapy is known to have healing and relaxing effects. Although these effects appear to be mediated by release of neurotransmitters and neurohormones, the specific neurohormonal systems involved have not been fully investigated.

OBJECTIVE

To assess the effects of a music therapy intervention on concentrations of melatonin, norepinephrine, epinephrine, serotonin, and prolactin in the blood of a group of patients with Alzheimer's disease.

DESIGN

Blood samples were obtained before initiating the therapy, immediately at the end of 4 weeks of music therapy sessions, and at 6 weeks follow-up after cessation of the sessions.

SETTING

Miami Veterans Administration Medical Center, Miami, Fla.

PATIENTS

20 male inpatients with Alzheimer's disease.

INTERVENTION

30- to 40-minute morning sessions of music therapy 5 times per week for 4 weeks.

MAIN OUTCOME MEASURES

Changes in melatonin, norepinephrine, epinephrine, serotonin, and prolactin following music therapy.

RESULTS

Melatonin concentration in serum increased significantly after music therapy and was found to increase further at 6 weeks follow-up. A significant increase was found between baseline values and data recorded after the music therapy sessions as well as at 6 weeks follow-up. Norepinephrine and epinephrine levels increased significantly after 4 weeks of music therapy, but returned to pretherapy levels at 6 weeks follow-up. Serum concentration of prolactin and platelet serotonin levels remained unchanged after 4 weeks of music therapy and at 6 weeks follow-up.

CONCLUSION

Increased levels of melatonin following music therapy may have contributed to patients' relaxed and calm mood.

Hypothyroidism and hyperthyroidism in the elderly

Thyroid disease in the elderly can be easily overlooked. Symptoms too often are explained away as normal processes of aging. Development of unstable illness, especially cardiac disease, is a frequent mode of presentation. One symptom or one clinical feature of thyroid disease in the elderly may be overwhelming in its presentation, as in apathetic hyperthyroidism, thyroid myopathy, depression and dementia. Physical examination of the thyroid gland can be helpful but in a high percentage of older patients the gland is normal to palpation. The treatment of hypothyroidism is straightforward. Only myxedema coma requires large doses of levothyroxine parenterally; all other forms of hypothyroidism are treated with oral levothyroxine. The dose is started very low and increased gradually over months. The euthyroid state is achieved gradually and safely. Hyperthyroidism can be treated by several modalities. In the unstable elderly patient, antithyroid medication can quickly produce a euthyroid state. When the patient is stable, further decisions can be made regarding definitive therapy. Radioactive iodine therapy is well-tolerated and effective. On occasion, a second course of therapy is needed to suppress hyperthyroidism. Close follow-up of all patients ever having received this therapy is needed to identify the development of hypothyroidism. Surgical thyroid ablation may be necessary in patients who fail to respond to radioactive iodine therapy. Abnormalities associated with unresolved thyromegaly, dysphagia, or tracheal compression may require surgical intervention. If suspicion exists that the gland is cancerous, surgical intervention is warranted.

Asthma therapy: present trends and future prospects

The short-term treatment of asthma has for years included supplemental oxygen, IV theophylline, and subcutaneously administered and inhaled beta-adrenergic agonists, anticholinergics, and corticosteroids. This regimen has not really changed. What have changed, however, are the specificity of the drugs and the mode of their administration. Metered-dose inhalers can deliver selective beta-adrenergic agonists, anticholinergics, and corticosteroids directly to the airway mucosa. Topical delivery of medication has dramatically reduced the side effects of all classes of medication. As experience accrues, more studies indicate that inhalation therapy may become the mainstay of asthma treatment, even in the emergency department. Metered-dose inhalers have also aided in the resurgence of the use of cromolyn. There is certainly improved ease of administration and perhaps a reduced incidence of rebound bronchospasm. The appearance of newer beta 2-adrenergic agonists with improved beta 2-adrenergic selectivity and longer half-lives underscores the activity in asthma research. There is hope that selective bronchodilating corticosteroids or calcium-channel blockers can be developed. Bronchodilating prostaglandins and leukotrienes, or inhibitors of prostaglandins and leukotrienes that cause bronchoconstriction, are being investigated. An oral mast-cell membrane stabilizer is available and hopefully can be improved. Finally, the transdermal delivery of medication may open an entirely new avenue for the treatment of those suffering from asthma.
