Introduction: There is a need to improve the psychosocial well-being of cancer patients. To date, intervention research has primarily focussed on improving psychosocial well-being through targeting singular aspects of care at the individual patient level. Sustainable, high-quality psychosocial care should address the issues faced by people diagnosed with cancer throughout the care pathway using a system-based approach.
Aims: To examine the number of intervention trials attempting to improve psychosocial cancer care that have implemented a system-based approach.
Method: Five journals were selected and relevant studies across all years were extracted. Four criteria, argued to be essential characteristics of system-based change, were assessed: (1) establishing a culture change within the healthcare system/organisation, through designated leaders who endorse organisational goals; (2) adopting a multidisciplinary approach to change; (3) mapping the system and identifying points of leverage; and (4) measuring the impact of change and adapting establish feedback loops.
Results: The search strategy returned 1174 citations, of which five met the inclusion criteria. Of the intervention studies identified, three met none of the four defined criteria for a systems-based intervention, one study met criterion 2 only, and one study met all four criteria, however, was not a rigorous study design.
Conclusions: This review of published psychosocial intervention trials in top-ranking psychosocial cancer care journals only found one study that met our criteria for evaluating system-based change. This is likely to be a consequence of the significant pragmatic and political barriers to conducting system-based intervention research.
