Older persons' medical encounters and their outcomes

This article reviews research on older patients and their doctors, with particular attention to the medical encounter between an elderly patient and his or her physician. Major categories of variables affecting the medical encounter include provider and patient characteristics (age, gender, ethnicity, education, values) and the context or setting of the encounter (site, presence of a patient's companion, and whether the visit is an initial one for the physician-patient pair). The process and content of medical encounters are affected by participant characteristics and context variables, and these in turn affect outcome variables such as participant satisfaction, adherence to treatment regimens, and medical outcome. Process issues include transfer of information, medical decision making, and interpersonal relations. Methodological issues are discussed, including problems with theory generation, lack of standardized methodology, gaps in research knowledge, and prior emphasis on descriptive studies as opposed to testing of interventions to improve elderly patient-physician communication.
