We Should Pay More Attention to Cross-sectoral Cooperation, Incentives and Practice-Oriented Evaluation Comment on "The Effect of Integrated Care After Discharge From Hospitals on Outcomes Among Korean Older Adults".

In their study, Choi and Yoo analysed a pilot project of the Koran government providing integrated care of older adults discharged from hospitals. The pilot project resulted in reduced length of home stay, cost reduction in total expenses and emergency visits for participants compared to controls, but increased hospital readmissions. This commentary provides actionable insights for stakeholders and researchers interested in testing, implementing and monitoring integrated care services in routine care settings. An essential requirement is that barriers and success factors of such projects need to be addressed in scientific evaluations. Also, understanding implementation projects as a continuous quality improvement process may increase knowledge gain and practical relevance of innovative initiatives. Furthermore, heterogeneity across healthcare providers, patient populations, and regions should be considered an asset from which different solutions can emerge. Regulatory authorities are in the position to create a framework so that stakeholders have the required scope for action.
