HMT's February Focus Survey deviates from the customary format to present the first segment of a multipart survey that was conducted by William Halverson, principal of Network Associates and a technical director for Pacific Bell's Healthcare Marketing Group. This first survey segment is designed to educate wide area network users about the multiple services that are offered within the U.S. market. General service availability and prices, as well as service descriptions and required equipment are covered in this segment of the survey. The remainder of Halverson's work will be published in the June issue of Health management Technology, and will detail service availability and prices for individual companies.
