Hospital characteristics and the use of computer processing and abstract services. A logistic analysis.

The use of computer processing and abstract services by hospitals is in a state of continuing change. Although many hospitals subscribe to abstract or turnkey systems, others are leaving shared services to set up their own in-house systems. To better understand the relationship between hospital characteristics and the use of computer processing and/or abstract services, data from the AHA 1982 Special Survey on Selected Hospital topic were analyzed using logistic regression analysis. Hospital size, ownership, and region were clearly related to the use of computer processing and/or abstract services for processing discharge data. Teaching status was also related to the use of abstract services, although teaching status hospitals also reported more reliance on in-house computer processing. Hospitals located in SMSAs and belonging to chains reported a higher use of discharge abstract services, and hospitals with higher operating margins were more likely to use abstract services on an "off-line" or batch-processing basis. The significance of these findings and their implications for abstract services are discussed.
