For health systems focused on optimizing the clinician’s experience, the decision to incorporate clinical workflow tools is an easy one. Mobile solutions are often used to fill voids in EHR-based workflows. However, since healthcare systems vary in terms of their informatics infrastructure, access to development resources, and experience in implementing new technology, health systems typically weigh the merits of two distinct paths: building an in-house solution or evaluating and implementing a vendor solution. Both options have a variety of strengths and weaknesses. In this session, the speakers will share Penn Medicine’s experience and approach utilizing their journey on each of these paths--implementing a vendor-built secure messaging solution and building a homegrown clinical workflow tool. They will describe the factors that influence homegrown vs. vendor decision, discuss barriers to implementation and how the solutions are sustained and financed by the healthcare system.
