The researchers used quality indicators developed for the Assessing Care of Vulnerable Elders (ACOVE) project. Forty-three quality indicators addressed 4 aspects of pharmacologic care. First, did patients receive medications that were indicated for their medical conditions? Second, did patients receive medications that were likely to do more harm than good? Third, did patients receive appropriate education about their medications and was there appropriate documentation about these medications and communication with other doctors? Fourth, did patients receive appropriate monitoring while using the medications? The researchers reviewed patients' medical records and interviewed patients or their caregivers to obtain information about each of the quality indicators relevant to each patient. They then examined how often and in what types of situations care met the quality standards.
