Public health care agencies lack the infrastructure to meet the increasing operational demands on them, but there is little comparative data on alternative operational structures and systems from which to formulate remedies. Improved information management systems could help address both the workload and the gathering of critically needed data. PC-based database and application programs (PC-APs) that communicate with the mainframe are proposed as a methodology for filling the information-processing gap between mainframe computing and manual information systems. We also propose a model for systematic study of information management systems in clinical settings which can be used to evaluate other aspects of clinical program operations as well. A pilot study demonstrating these methodologies suggests that this is a fruitful approach to assessing ambulatory care operations and that PC-APs can improve administrative and clinical functions and enhance FTE productivity at lower overall cost.
We collected 69 questions generated by physicians based on their active patient medical records. Each question was associated with a single term in a specific record (Key Term). These questions were analyzed with respect to word content and concept content. Concepts were matched to the National Library of Medicine's Metathesaurus (Meta-1). Sixty-eight Key Terms were completely matched by Meta-1 terms. Each question matched to an average of 3.7 Meta-1 terms for a total of 255 concepts. Based on word count, these 255 concepts accounted for 43%, stop words accounted for 36%, and numbers and drug trade names accounted for 3% of the words. The remaining 18% of the words could be matched to 143 concepts not in Meta-1. Review of all concepts showed that they could be divided into medical terms (Noun Concepts), modifiers (Modifier Concepts), and concepts that provided context for the questions (Relation Concepts). The majority of Relation Concepts did not match concepts in Meta-1. A vocabulary of Relation Concepts would provide a useful starting point for a computer system designed to aid physicians in answering these questions.
Automated ambulatory medical records systems (AAMRSs) have been operational for over 20 years but have not been adopted by more than a small fraction of their potential users. This paper presents a detailed analysis of the uses and benefits of the COSTAR-based AAMRS at the Harvard Community Health Plan and of the factors which have inhibited the dissemination of COSTAR. We conclude that AAMRSs have been an orphan technology and cite trends in health care that favor the future development of AAMRSs.
