“…Several studies noted that a system-wide approach is needed to improve patient management, while taking into account competing hospital priorities [11,41,44,45,49,55,82,84,90,91]. The articles relied on various systems-based frameworks for investigating patient management, including the concept of High Reliability Organisations (HRO) [16,43]; lean management models [23,83,86,90]; Plan-Do-Study-Act [49,75,85,90]; quality improvement (QI) [83,85,92,93]; process mapping/tracking [78,81,83,85]; Ishikawa Diagrams [78,83]; and Design-Measure-Analyse-Improve-Control (DMAIC) [83]. One paper described a systems engineering approach to analyse and maximise capacity in one health system for BAU, which resulted in the establishment of a centralised capacity command center [41].…”
