This article reports on a new instrument, the Geriatric Institutional Assessment Profile (GIAP), developed to assess (1) hospital workers' knowledge, attitudes, and perceptions regarding care of geriatric patients, and (2) the perceived adequacy of an institutional environment to serve geriatric patients' needs. Findings are reported from 303 questionnaires completed by health care employees from a 658-bed academic medical center. Internal consistency estimates were consistently high for the various components of the GIAP. Factor analysis was performed to examine underlying dimensions of knowledge and institutional environment. The GIAP has the potential to narrow the gap between actual and best practice in geriatric care by identifying staff information needs and concerns, as well as institutional barriers and facilitators to providing quality geriatric hospital care.
