Evaluating IAIMS at Yale: information access.

OBJECTIVE: To evaluate use of information resources during the first year of IAIMS implementation at the Yale-New Haven Medical Center. The evaluation asked: (1) Which information resources are being used? (2) Who uses information resources? (3) Where are information resources used? (4) Are multiple sources of information being integrated? DESIGN: Measures included monthly usage data for resources delivered network-wide, in the Medical Library, and in the Hospital; online surveys of library workstation users; an annual survey of a random, stratified sample of Medical Center faculty, postdoctoral trainees, students, nurses, residents, and managerial and professional staff; and user comments. RESULTS: Eighty-three percent of the Medical Center community use networked information resources, and use of resources is increasing. Both status (faculty, student, nurse, etc.) and mission (teaching, research, patient care) affect use of individual resources. Eighty-eight percent of people use computers in more than one location, and increases in usage of traditional library resources such as MEDLINE are due to increased access from outside the Library. Both survey and usage data suggest that people are using multiple resources during the same information seeking session. CONCLUSIONS: Almost all of the Medical Center community is using networked information resources in more settings. It is necessary to support increased demand for information access from remote locations and to specific populations, such as nurses. People are integrating information from multiple sources, but true integration within information systems is just beginning. Other institutions are advised to incorporate pragmatic evaluation into their IAIMS activities and to share evaluation results with decision-makers.

The MEDLINE experience at Yale: 1986-1996.

The Cushing/Whitney Medical Library began providing end-user access to MEDLINE in 1986 and switched to the OVID system in 1993. MEDLINE is a core service of the library, and the choice of delivery systems has had a significant impact throughout the Yale-New Haven Medical Center. This paper describes the user response to MEDLINE, discusses the effects of MEDLINE on other library services, and suggests ways in which technology, policy, and funding have influenced use. Yale's experience suggests that removing barriers in all three areas can dramatically expand the points of access, the number of users, and the amount of use with manageable effects on other library services.
