Adopting information technology in hospitals: the relationship between attitudes/expectations and behavior.

The purpose of this field study was to measure the influence of three factors on the adoption of information technology in a health care setting--namely, attitudes toward using the technology, subjective norms or beliefs about others' expectations, and perceived voluntariness. Approximately 77 percent of the variance of intent to use the technology was explained by three attitude variables (beliefs related to perceived relative advantage and compatibility with previous work patterns as well as result demonstrability), and one variable associated with subjective norms (influence of a senior policymaker, the director of nursing). Use of this model may provide insights for administrators managing the process of information technology implementation in health care.
