Dissemination and implementation strategies in software requirements elicitation

Clinical software is a fundamental tool for supporting healthcare systems because it improves the quality of patient care and automatizes the most frequently performed clinical tasks. Nevertheless, since health systems include various components, such as supplies, transportation, laboratories, and interoperability, eliciting the most critical requirements for understanding the problem that the clinical software must solve is quite a complex task. Indeed, the requirement elicitation process may directly determine the success or failure of the clinical software. In this article, we present the D&I framework, a methodology that uses dissemination and implementation strategies to recommend guidelines for the elicitation of clinical software requirements. The objective of this framework is to support software developers in the identification of key requirements with the goal of more holistically understanding the problem to be solved by the clinical software. We evaluated the D&I framework with a real case study related to a bed management system. We employed a usability instrument with 50 clinicians to evaluate tasks in software modules that represent clinical priorities defined by stakeholders. The results indicate that the perception of usability by end-users is acceptable, suggesting that the evaluated tasks satisfy the established clinical priorities. The D&I framework provides a starting point for research and discussion about the contribution of dissemination and implementation strategies to the body of knowledge about requirement engineering.
