A meta-model for computer executable dynamic clinical safety checklists

Table 1 Mapping dynamic checklist concepts to BPMN concepts

Checklist concept	BPMN concept	Explanation
Clinical pathway	Process	A clinical pathway is a kind of process.
Care flow	Sequence flow, Gateways, Ad-hoc subprocess	A care flow specifies how two or more clinical tasks are connected.
Sequential flow	Sequence flow	Two tasks are executed sequentially.
Parallel flow	Parallel gateway	Two tasks are executed simultaneously.
Conditional flow	Exclusive gateway, Inclusive gateway	The succeeding task can only be executed if some conditions are met.
Ad-hoc flow	Ad-hoc subprocess	Tasks are executed without a specific order.
Clinical activity	Task	A clinical activity is a clinical-oriented task.
Clinical task	User task	A clinical task is a clinical-oriented user task.
Potential owner	Potential owner	A potential owner is an expected owner of a clinical task.
Role	Resource role	A role is the clinical role of a potential owner. A potential owner may have one or more roles.
Safety guard activity	User task	Safety guard activity is a clinical task dedicated to preventing potential medical errors.
Potential problem	N/A	Potential problem describes what possibly might go wrong while performing a clinical task.
Trigger	N/A	A trigger is a description of when should a safety guard activity be executed.
