PROBLEM TO BE SOLVED : To provide a system for implementation of a chemical request corresponding to a chemical inclusion unit and a related method. SOLUTION : The system of the invention can comprise a request implementation logic for providing determination data which is used for selecting one out of plural different implementation places by which a given chemical request is implemented, to a care provider of a patient. A request router can send the chemical request to the selected one out of the plural implementation places. The implementation place can provide chemical request metadata (for example, data related to preparation and handling of the chemical) to a chemical request database corresponding to the chemical request implemented by the implementation place. The chemical request metadata can be stored in the chemical request database, and to which access is possible for promoting improvement of a management function related to a chemical which is distributed by a care provider of a patient.
