PurposeQuality improvement collaboratives (QICs) are a popular approach to improving healthcare services and patient outcomes. This paper evaluates a QIC implemented by a large, integrated healthcare organisation in Wales in the UK.Design/methodology/approachThis evaluation study draws on two well-established evaluation frameworks: Kirkpatrick's approach to gather data on participant satisfaction and learning and Stake's approach to gather data and form judgements about the impact of the intervention. A mixed methods approach was taken which included documentary analysis, surveys, semi-structured interviews, and observation of the QIC programme.FindingsTogether the two frameworks provide a rounded interpretation of the extent to which the QIC intervention was fit-for-purpose. Broadly the evaluation of the QIC was positive with some areas of improvement identified.Research limitations/implicationsThis study is limited to a QIC conducted within one organisation. Further testing of the hybrid framework is needed that extends to different designs of QICs.Practical implicationsA hybrid framework is provided to assist those charged with designing and evaluating QICs.Originality/valueEvaluation studies are limited on QICs and if present tend to adopt one framework. Given the complexities of undertaking quality improvement within healthcare, this study uniquely takes a hybrid approach.
