Roles for knowledge-based computer systems: Case studies in maternity care

Abstract

The design of medical knowledge-based computer systems requires effective interdisciplinary communication for the development of a community sharing common goals and a common language for design. Over the past 9 years the Perinatal Research Group, an interdisciplinary team of computer scientists, engineers and clinicians, have developed a prototype knowledge-based computer system to aid clinicians in the care of women in labour. The group were uncertain which approach to adopt to progress this system from a prototype to a useful clinical tool to support decision making. A case study and activity theory analysis, of an existing clinical knowledge-based computer system in routine use, helped to resolve a number of communication and methodological issues that the design team encountered. Sharing of backgrounds and perspectives caused the design team to question previous assumptions and to explore alternative functions and roles for knowledge-based computer systems in maternity care. We are now undertaking a longitudinal case study and activity theory analysis of obstetric teams and women in labour to analyse the relationships between clinicians, patients and technology. This work will inform the development of our knowledge-based computer system to place the patient at the centre of the decision-making process.
