Objective Structured Video Examinations (OSVEs) for geriatrics education.
The Medical College of Wisconsin (MCW) and the Wisconsin Geriatric Education Center (WGEC) are committed to developing educational materials for primary care physicians in training. In response to the opportunity created by the Accreditation Council for Graduate Medical Education (ACGME) competency mandate, an MCW-led interdisciplinary working group has developed competency-linked video-based assessment tools for use in primary care residency training programs. Modeled after the Objective Structured Clinical Examinations (OSCE), used as part of the medical licensing examination process, we created geriatric-focused Objective Structured Video Examinations (OSVEs) as a strategy to infuse geriatrics into residency training. Each OSVE tool contains a 1-3 minute video trigger that is associated with a series of multiple choice and/or constructed response questions (e.g., fill in the blank). These questions assess residents' understanding of video-demonstrated ACGME competencies including professionalism, systems-based practice, communication, and practice-based learning. An instructor's guide and scoring key are provided for each tool. Response to the OSVEs has been overwhelmingly enthusiastic including greater than 90% commitment by statewide faculty to use the tools in residency training.

The Medical College of Wisconsin's program to strengthen geriatrics education.
Medical care for geriatric patients requires physician training that promotes the acquisition of attitudes, knowledge and skills that will permit future practitioners to meet the health needs of increasing numbers of aged patients. MCW has strengthened its traditional curriculum by focusing on student attitudes in the early pre-clinical years through outreach and interest groups programs. Knowledge is integrated throughout the 4-year curriculum using our aging virtual patients. These patients are a teaching resource to the entire faculty. Attitudes, knowledge, and skills in geriatrics are further developed through an M3 geriatrics medicine option and the M4 Integrated Selective. Geriatric-specific skills are emphasized through the use of standardized patients and objective structured clinical examinations in the M4 Selective. It is anticipated that these students efforts will create interest in a novel residency experience (Med-Ger) that will ensure that upon successful completion of the program, residents are expert in geriatric medicine practice and meet criteria for board certification in geriatric medicine.
The underuse of therapy in the secondary prevention of hip fractures.
There is strong evidence to indicate that individuals who sustain a hip fracture are at a greater risk of developing another. The management of such patients should include efforts to prevent future fractures, including prescribing medications that have been shown to lower hip fracture risk. Such therapies that are currently available include calcium and vitamin D supplementation, alendronic acid and risedronic acid. In addition, there is epidemiological evidence to indicate that estrogen may also decrease the risk of hip fracture. Parathyroid hormone is another agent that has shown promise in this regard and is likely to be available for clinical use in the near future. However, the rates of utilisation of these therapies among patients with hip fractures are low. It is important to emphasise that secondary prevention of hip fractures should be an integral part of the management of individuals who sustain hip fractures.
Role of hormones in the pathogenesis and management of sarcopenia.
There is growing evidence to indicate that age-related declines in growth hormone (GH), insulin-like growth factor (IGF)-1, and androgen and estrogen production play a role in the pathogenesis of sarcopenia (an age-related decline in muscle mass and quality). Although GH supplementation has been reported to increase lean body mass in elderly individuals, the high incidence of adverse effects combined with a very high cost has limited the applicability of this form of therapy. The assessment of an alternative approach to enhance the GH/IGF-1 axis in the elderly by using GH-releasing hormone and other secretagogues is currently under way and is showing some promise. Testosterone replacement therapy may increase muscle mass and strength and decrease body fat in hypogonadal elderly men. Long-term randomised, controlled trials are needed, however, to better define the risk-benefit ratio of this form of therapy before it can be recommended. Available data are currently insufficient to decide what role estrogen replacement therapy may play in the management of sarcopenia. Therefore, although the evidence linking age-related hormonal changes to the development of sarcopenia is rapidly growing, it is still too early to determine the clinical utility of hormonal supplementation in the management of sarcopenia.
Minor depression and rehabilitation outcome for older adults in subacute care.
During recent years, numerous studies have found an association between minor depressive symptoms and physical functioning for older adults recuperating from illness or injury Whereas earlier research has focused on the effects of minor depression during rehabilitation in acute or long-term settings, this study examined 209 patients receiving subacute physical therapy. The dependent measures were total score changes on the Functional Independence Measure (FIM) obtained at admission, discharge, and 3-month follow-up. The independent measure was minor depressive symptoms, as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, obtained within 5 days of admission. A binary logistic regression analysis was conducted with dichotomized FIM scores and the presence/absence of minor depressive symnptoms. The results indicated a statistically significant relationship between FIM score change and minor depression from admission to discharge, but not from discharge to follow-up.
