Multiple outcome interactions in healthcare systems: a participatory outcome mapping approach

Outcomes, which are the result state or condition from a process or intervention, are essential elements of healthcare system design and an important indicator of performance. They are included in well-known system analysis frameworks such as the Systems Engineering Initiative for Patient Safety (SEIPS) and Cognitive Work Analysis (CWA). However, fewer practical approaches exist for understanding and communicating interactions among healthcare outcomes. This study applies a novel mapping method as a practical approach to collect, aggregate and visualise interrelations among multiple healthcare outcomes. Graphic facilitation mapping sessions with eleven healthcare providers and ten patients with chronic conditions were conducted. Participants created outcome interrelationship maps following a six-step process. Two outcome-based network visualisations were synthesised using network analysis. This outcome-based approach advances how we frame healthcare systems, focussing on accommodating multiple stakeholders' visions, understanding interrelations, and defining trade-offs. This practical approach may complement frameworks such as SEIPS and CWA. Practitioner summary: The presented outcome-based mapping approach can facilitate the understanding of outcomes as part of the interrelated healthcare system. The approach allows the discussion and integration of different stakeholders' outcome priorities to identify critical elements and better inform the development or adaptation of healthcare systems.
