Quality dimensions of readmission risk prediction models

Dimension	Key domain	Description of barrier
Development	Validation	Inadequate validation causing poor model discrimination when generalised
	Features	Over-reliance on biomedical features from administrative and claims data
	Timeframe	Possibility that the 30-day timeframe is not optimal for accurate prediction
	Data access	Dependence on inaccessible, low quality, outdated or manually entered data
Implementation	Resources	Insufficient personnel, statistical expertise or financial resources
	Vision	Lack of leadership, purpose or policy priorities related to readmission prediction
	Clinical relevance	Unclear clinical utility, actionability or relevance
	Workflow integration	Poor integration into the clinical workflow
	Maintenance	Inadequate maintenance or continuous improvement
