Requirements development for a patient computing system.

Critical parts of the software development life cycle are concerned with eliciting, understanding, and managing requirements. Though the literature on this subject dates back for several decades, practicing effective requirements development remains a current and challenging area. Some projects flourish with a requirements development process (RDP) that is implicit and informal, but this approach may be overly risky, particularly for large projects that involve multiple individuals, groups, and systems over time. At Partners HealthCare System in Boston, Massachusetts, we have applied a more formal approach for requirements development to the Patient Computing Project. The goal of the project is to create web-based software that connects patients electronically with their physician's offices and has the potential to improve care efficiency and quality. It is a large project, with over 500 function points. Like most technological innovation, the successful introduction of this system requires as much attention to understanding the business needs and workflow details as it does to technical design and implementation. This paper describes our RDP approach, and key business requirements discovered through this process. We believe that a formal RDP is essential, and that informatics as a field must include proficiencies in this area.

Storage and retrieval of coded patient diagnoses and data on a clinical laboratory computer system.

A system has been developed which allows for easy storage and retrieval of patient diagnoses using ICD-9-CM codes. Entered codes are automatically interpreted by the computer and then both the code and the interpretation are stored as in integral part of the patient record. Teaching clinicians may use an automated, keyword-search algorithm to display the code for a diagnosis of interest and then use that code to find any hospitalized patient with such a primary or secondary diagnosis. Entered diagnoses automatically appear on worksheets in the clinical laboratory. Retrospective studies also may be performed whenever a pathologist wants to compare diagnoses with laboratory results.

The effectiveness of a hospital bedside computer system.

A hospital implemented a computerized documentation system using planned change. Nursing staff and managers were instrumental in reviewing and choosing a system, and implementing and evaluating project results. The project was successful and raised some critical ethical and legal issues.
