Abstract
Rural physicians need access to digital health sciences libraries (DHSLs) that is easy and reasonably rapid. The goal of this project was to study rural hospitals' access to a DHSL on the Internet, by comparing differing access speeds with differing costs and their acceptability for retrieving text, image, and video information in a DHSL.
DHSL system response time was measured at three different times during the day over three different types of network connections (T1, Frame Relay, Modem). Text, image, and video information was retrieved. Costs were determined for installation and operation of the different types of network connections.
System response times were consistent at the three different testing times for each media type retrieved by each of the three network connection types. System response times for text retrieval met literature standards for all connections. Image retrieval met literature standards for T1 and Frame relay connections. No connection met literature standards for video retrieval.
High speed access to DHSLs is preferable; Frame relay connections provide substantively similar service as T1 connections at less cost. However, access via modem to a DHSL can provide access to the majority of information--text--in a DHSL with an acceptable system response time.
