The overall goal of the Systems Engineering, Usability, and Integrative Data Analytics(SEUI) Core is to leverage health systems engineering approaches to support the development of the individual Patient Safety Learning Lab projects, as well as their integration as a “system-of-systems”.

We have four specific aims:

  • Aim 1: Explore how the overall “system-of-systems” (SOS) functions under various risk states/conditions by validating a model of unit-based risk and usage of individual project tools.

  • Aim 2: Identify and provide appropriate systems design and engineering methods (e.g., statistical process control (SPC) charting, simulation modeling, failure modes effects analysis) to support use of individual project tools by patients and providers under all conditions. 

  • Aim 3: Provide human factors expertise to address user relationship and interface with the environment, the software, and the system as an integrated whole. 

  • Aim 4: Optimize implementation and performance of PSLL patient and provider engagement technical infrastructure through collaborative data analysis.  


The SEUI Core will support each of the PSLL projects with systems engineering and human factors usability methods appropriate to those projects. These approaches will maximize integration and performance with our EHR and safety reporting systems. We will accomplish these goals by modeling the overall system of systems as well as by refining our work for implementation in local contexts. 

As a general rubric, these activities will align with a continuous safety improvement process (Figure 1) including surveillance to identify at risk-patients, individualized risk assessment of threats to identified patients, mitigation strategies to reduce harm likelihood, and systematic analysis of threats and harms identified in the first 3 phases in order to iteratively refine this overall system of safety over time.
