    This study evaluated the relation between hospital- and surgeon volume and different risk-adjusted outcomes after oesophago-gastric (OG) cancer surgery in England between 2011 and 2013. In data from the National Oesophago-Gastric Cancer Audit from the UK, multivariable random-effects logistic regression models were used to quantify the effect of surgeon and hospital volume on three outcomes: 30-day and 90-day mortality and anastomotic leakage.

    The authors draw attention to the fact that there is a lot to be gained from bringing together transitional care programmes with approaches that address the wider health system environment in order to address the increasing complexity in the management of care transitions. They aim to illustrate the application of organizational models to improve quality and safety using an international best-practice example. The chapter ends with recommendations for policymakers, health care decision-makers and evaluators regarding the alignment of theory, model specification, implementation and attribution of quality and safety outcomes to effects.

    Healthy Kinzigtal is the only fully population-based system in Germany that has been subject to rigorous external evaluation. The authors describe the evaluated success of Healthy Kinzigtal in improving quality and care experience, while reducing costs. They also show a number of conditions need to be met to ensure that the results can be scaled up and successfully replicated elsewhere.

    For the standard work "Handbook Integrated Care", Gröne and Hildebrandt present the development from Healthy Kinzigtal to one of the most well-known best practice models in the field of integrated care. They outline important framework conditions for a successful adaptation based on associated evaluation studies.
