PurposeThis paper aims to present the impact evaluation findings from a multiprofessional leadership programme commissioned in the South East of England to support primary care networks (PCNs) to lead system improvement together. It identifies programme impact at micro and meso system levels; a leadership impact continuum that can be used by individuals and teams to evidence impact of improvements in PCN practices; the learning and development strategies that were effective and proposes implications for other networks. Design/methodology/approachMixed methods underpinned by practice development methodology were used to explore the impact of the programme on two practitioner cohorts across 16 PCNs. Data were collected at the start, mid-point and end of the eight-month programme. FindingsResults illustrate an innovative approach to collective leadership development. A continuum of impact created with participants offers insight into the journey of transformation, recognising that “change starts with me”. The impact framework identifies enablers, attributes and consequences for measuring and leading change at micro, meso and macro levels of the health-care system. Participants learned how to facilitate change and collaboratively solve problems through peer consulting which created a safe space for individuals to discuss workplace issues and receive multiprofessional views through action learning. These activities enabled teams to present innovative projects to commissioners for service redesign, enabling their PCN to be more effective in meeting population health needs. The authors believe that this programme may provide a model for other PCNs England and other place-based care systems internationally. Originality/valueThis study offers insight into how to enable a journey of transformation for individuals and PCN teams to enhance team effectiveness and collective leadership for system-wide transformation required by the National Health Service Long Term Plan (2019).
