Anxiety Disorders Among Older Primary Care Patients

Data from the 1997 National Ambulatory Medical Care Survey (NAMCS) were accessed to obtain information about naturalistic patterns of recognition, service utilization, and treatment for late-life anxiety in primary care. The NAMCS is a national probability sample survey of office visits to non-Federal, U.S. physicians engaged in patient care. The survey was conducted by the Division of Health Care Statistics, National Center for Health Statistics, and Centers for Disease Control and Prevention (CDC). Data are now in the public domain. For the current report, all cases indicating office visits for patients age 60 and older were selected (n = 7,687). Anxiety disorders were assigned for 1.3% (n = 99) of these visits, with anxiety disorder NOS the most frequent diagnosis. For 20.2% of these visits (n = 20), a coexistent depressive disorder also was diagnosed. Depression without coexistent anxiety was diagnosed for 2.3% of all visits (n = 176). These figures suggest that late-life anxiety may often go unrecognized and may be more difficult to detect than depression. Nevertheless, other data indicate that appropriate pharmacological treatment and mental health services or referrals are often provided when anxiety or depression is recognized. However, visits wherein these disorders are recognized require increased physician time, and significant proportions of patients in some groups may still not receive appropriate mental health care. Results are discussed in terms of the nature of usual care for late-life anxiety and the needs for future research.
