Reframing Super-Utilization: A Complex Systems Review of Cost-Focused Interventions in High-Need, High-Cost Care. Radical Transformation is Needed

Le résumé fourni par la source

Super-utilization, defined as frequent and often avoidable use of emergency departments and hospital admissions, has attracted significant policy and research attention due to its impact on healthcare costs. Over the past decade, care management and integrated care interventions have been promoted as solutions to reduce per capita expenditure and service use. However, systematic reviews and primary studies consistently report limited success in shifting utilization patterns or improving care experiences. This scoping review explores the conceptual evolution of super-utilization and examines whether current approaches reflect the underlying complexity of the health system and patient needs. The three-phase scoping and complexity-informed review aimed to identify the evolution of Super-utilization as an issue and its key drivers, in relation to the dynamic systems in which it occurs. The findings reveal a predominant emphasis on cost containment and acute care metrics, with minimal incorporation of person-centred outcomes, lived experience, or local system dynamics. Even when addressing social determinants, interventions remain narrowly focused on utilization. Super-utilization reflects multi-level dynamics—biological, psychological, social, and political—yet these are rarely integrated into program design or evaluation. Centralised policy frameworks such as the Triple Aim risk reinforcing inequities unless they actively address under-resourced populations and the complexity of chronic illness and ageing. Radical transformation of policy is required to make the nature of care of high cost/high need super-utilizers central to quality metrics that may improve outcomes rather than inappropriate utilization metrics which make little impact on health care costs. This review concludes that super-utilization requires a shift in paradigm toward systems-informed, needs-based approaches that integrate complexity theory and distributive justice to guide future research and interventions.
