Role of risk assessment and bone density monitoring in osteoporosis.

Osteoporosis and its complications are prevalent medical problems. Of the risk factors for fractures, low bone mass is the best predictor. Measuring bone density in a person with risk factors for osteoporosis can provide important information for both patient and physician when choosing clinical interventions. For patients with the disease it is a way to assess response to drug therapy. Advances in technology have made measuring bone density safer, faster, and more practical than ever. Guidelines addressing when, where, and how the test should be done are useful when deciding how to apply this technology to patient care.

Optimal medication use in elders. Key to successful aging.

Pharmacotherapy represents one of the most important ways in which the practice of geriatric medicine differs from conventional medical care. The older patients is a major consumer of prescription and nonprescription medications, and proper use of these agents can lead to more cost-effective strategies in reaching optimal health. A key difference in distinguishing appropriate from inappropriate drug use is evident in the themes of polymedicine and polypharmacy. Polymedicine describes the use of medications for an older population for the treatment of multiple co-morbid conditions, while polypharmacy represents a less-than-desirable state with duplicative medications, drug-to-drug interactions, and inadequate attention to pharmacokinetic and pharmacodynamic principles. The purpose of this paper is to outline strategies toward optimal medication use as a key to successful aging. Specifically, we discuss themes of cost-effective prescribing, the role of medication compliance, overuse and underuse of medication, over-the-counter products, alcohol abuse, and preventive medicine. In addition, we discuss policy implications and responsibility for ensuring the high quality of pharmaceutical care. The reader should have a practical understanding of the pertinent issues in geriatric clinical pharmacology and its relationship to successful aging.

Assessment of medication management skills in older outpatients.

OBJECTIVE: To identify risk factors for poor medication management skills in community-dwelling older adults by using a performance-based medication management assessment instrument. DESIGN: A cross-sectional investigation. SETTING: A university outpatient geriatric assessment clinic. PARTICIPANTS: Fifty-nine community-dwelling older adults aged 62-102 years. MEASUREMENTS: Patients were assessed on their ability to perform medication management tasks, including reading prescription labels, interpreting medication instructions, opening safety-capped vials, removing tablets from vials, and differentiating tablet colors. The Mini-Mental State Examination (MMSE) was administered and the Katz index of activities of daily living was obtained during the same clinic visit. RESULTS: Cognitive impairment (MMSE < 24) and physical dependency (Katz > or = 1) were both found to be risk factors for the inability to perform individual tasks and independent risk factors for poor overall outcome on the medication management assessment, odds ratios (95% confidence interval) 9.39 (7.82 to 10.96) and 7.24 (5.60 to 8.88), respectively. Age, gender, education, or number of prescription medications were not associated with the ability to perform individual tasks or to overall outcome on the medication management assessment. CONCLUSIONS: Cognitive deficits and physical dependency appear to be strong predictors for the inability to perform tasks associated with medication management. Assessment of medication management skills in older adults living in the community may help identify specific problems, aid in planning patient care, and promote independence.

Effect of the Omnibus Reconciliation Act 1987 on antipsychotic prescribing in nursing home residents.

OBJECTIVE: To determine the impact of OBRA 87 on antipsychotic prescribing in a 485-bed nursing home. DESIGN: Twelve-month retrospective cohort review of medical charts, medication administration records, and computerized pharmacy records. MEASUREMENTS: The percent of residents by diagnostic group and antipsychotic use. MAIN RESULTS: An attempt was made to stop or lower the dose of antipsychotic in 75% of the 107 residents studied. Antipsychotics were stopped in 45% of residents with a dementia-only diagnosis and 25% of residents with a psychiatric diagnosis (P < 0.05). Residents with documented symptoms appropriate for the use of antipsychotic, per OBRA 87, were significantly less likely to have their antipsychotic stopped. Twenty percent of residents whose antipsychotic was either stopped or its dose lowered had the agent restarted or its dose increased. CONCLUSION: OBRA 87 had a significant impact on antipsychotic use in this facility.

Perceived purpose of prescription drugs: the Iowa 65+ Rural Health Study.

In order to assess elderly patients' knowledge of their medications, the Iowa 65+ Rural Health Study asked a rural, elderly population the purpose of their prescription drugs. Ten percent of all drug purposes reported were considered inappropriate by our criteria. There was some variability between therapeutic categories and their frequency of purpose misperception. For 40 percent of drugs whose purpose was inappropriate, the respondent reported another drug for which that purpose would have been appropriate. Respondents were as likely to state a medication's appropriate purpose whether it had been dispensed by a pharmacy or a physician. The highest percentage of drugs whose purpose was appropriately perceived was dispensed by mail-order pharmacies.
