BackgroundHealthcare organisations strive to meet their current and future challenges and need to increase their capacity for continuous organisational improvement and learning (COIL). A key aspect of this capacity is the development of COIL capability among employees.ObjectiveThis systematic review aims to explore common attributes of interventions that contribute to the development of COIL capability in healthcare organisations and to explore possible facilitating and hindering factors.MethodsA comprehensive search was conducted in Scopus, MEDLINE and Business Source Complete for primary research studies in English or Swedish, in peer-reviewed journals, focusing on organisational improvements and learning in healthcare organisations. Studies were included if they were published between 2013 and 23 November 2022, reported outcomes on COIL capability, included organisations or groups, and were conducted in high-income countries. The included articles were analysed to identify themes related to successful interventions and factors influencing COIL capability.ResultsThirty-six articles were included, with two studies reporting unsuccessful attempts at increasing COIL capability. The studies were conducted in nine different countries, encompassing diverse units, with the timeframes varying from 15 weeks to 8 years, and they employed quantitative (n=10), qualitative (n=11) and mixed methods (n=15). Analysis of the included articles identified four themes for both attributes of interventions and the factors that facilitated or hindered successful interventions: (1) engaged managers with a strategic approach, (2) external training and guidance to develop internal knowledge, skills and confidence, (3) process and structure to achieve improvements and learning and (4) individuals and teams with autonomy, accountability, and safety.ConclusionThis review provides insights into the intervention attributes that are associated with increasing COIL capability in healthcare organisations as well as factors that can have hindering or facilitating effects. Strategic management, external support, structured processes and empowered teams emerged as key elements for enhancing COIL capability.
