<p>The population continues to age, creating ever-increasing demands on physicians to care for older adults. With a shortage of fellowship-trained geriatricians, primary care providers will increasingly be called upon to care for the aging population. In 2010, the essential geriatric competencies for Internal Medicine (IM) and Family Medicine (FM) residents were published, the result of input from program directors and clinical educators from a variety of specialties and professional organizations. To reinforce and disseminate these critical skills, we created a quick reference web application for IM and FM residents that addresses competencies in each of the seven key competency domains: <ul><li>Medication Management</li><li>Cognitive, Affective and Behavioral Health</li><li>Complex or Chronic Illness</li><li>Palliative and End-of-Life Care</li><li>Hospital Patient Safety</li><li>Transitions of Care</li><li>and Ambulatory Care</li></ul></p><p>This web application can be used as a comprehensive reference by learners of multiple levels and disciplines while caring for patients in a variety of settings, including inpatient wards, outpatient clinic, nursing homes and home visits. Various screening tools, criteria, mnemonics and guidelines supporting each competency are included in this concise guide to caring for aging adults.</p>
