Abstract
Statement of the Problem: Healthcare providers are always seeking for innovation based on engineering and information technology to improve care quality, manage risk, and reduce service cost. To develop this kind of innovation requires understanding of complex requirements including medical safety, patient privacy, patient pathology, clinical standard practice guideline, resource constraint, and change resistance. When requirements are unclear or unmanaged, a design can be too complicate to build or too expensive to maintain. A requirement engineering framework helps reducing under-clarification and promoting a viable design for healthcare technology related innovative system. The purpose of this study is to present a framework of requirement engineering in developing innovative systems for emergency healthcare and IPD care services.
Methodology & Theoretical Orientation: An adaptive requirement engineering framework based on conventional SDLC and agile model was utilized during requirement gathering and development of two systems: Mobile Stroke Unit and Preventing pressure ulcer in immobilized patients. The systems were implemented and tested in compliance with functional and non-functional requirements acquired and confirmed by the framework to understand its performance and validity.
Findings: In case of a Mobile Stroke Unit (MSU), the framework reduces time of design and implementation by 30% and supports objective of MSU in which the total time of CT scan + diagnosis by Cerebrovascular neurologist + rt-PA administration must be within 3.5 hours from onset. In pressure ulcer prevention, the framework provides a cost-effective system to support a clinical nursing practice guideline of 2-hour repositioning, promote patient-nurse relationship and reduce cases of pressure ulcer.
Conclusion & Significance: An engineering requirement framework is important for healthcare technology related innovation. The framework is usually under-recognized. This study recommends that the framework shall be implemented in all processes of innovation development.
