Gaps, traps, bridges and props: a mixed-methods study of resilience in the medicines management system for patients with heart failure at hospital discharge.

Poor medicines management places patients at risk, particularly during care transitions. For patients with heart failure (HF), optimal medicines management is crucial to control symptoms and prevent hospital readmission. This study explored the concept of resilience using HF as an example condition to understand how the system compensates for known and unknown weaknesses. We explored resilience using a mixed-methods approach in four healthcare economies in the north of England. Data from hospital site observations, healthcare staff and patient interviews, and documentary analysis were collected between June 2016 and March 2017. Data were synthesised and analysed using framework analysis. Interviews were conducted with 45 healthcare professionals, with 20 patients at three time points and 189 hours of observation were undertaken. We identified four primary inter-related themes concerning organisational resilience. These were named as gaps, traps, bridges and props. Gaps were discontinuities in processes that had the potential to result in poorly optimised medicines. Traps were features of the system that could produce errors or unintended adverse medication events. Bridges were features of the medicines management system that promoted safety and continuity which ensured that, despite varying conditions, care could be delivered successfully. Props were informal, temporary or impromptu actions taken by patients or healthcare staff to avoid potential adverse events. The numerous opportunities for HF patient safety to be compromised and for suboptimal medicines management during this common care transition are mitigated by system resilience. Cross-organisational bridges and temporary fixes or 'props' put in place by patients and carers, healthcare teams and organisations are critical for safe and optimal care to be delivered in the face of continued system pressures.
