2 2 ©2010 University Hospitals of Geneva Context Critical treatmentsCritical treatments Dangerous productsDangerous products Severe consequences in case of error or misuseSevere consequences in case of error or misuse High costs of products, often low usability durationHigh costs of products, often low usability duration  Need for securing the whole process – from the prescription to the administration  Protocol driven prescription in the CPOE  Protocol driven production in the pharmacy  Avoidance of manual work at all places:  prescription, production, administration  Traceability of products and actions

3 3 ©2010 University Hospitals of Geneva Phases 1.Prescription Prescription of a protocol = set of medications, with specific dosages and calendar of administrationPrescription of a protocol = set of medications, with specific dosages and calendar of administration 2.Reception by the central pharmacy One or several medications taken in charge at a timeOne or several medications taken in charge at a time Preparation of the everything required for the fabricationPreparation of the everything required for the fabrication 3.Fabrication of the specific medication Combination of the ingredients for producing the specific medication for a specific patientCombination of the ingredients for producing the specific medication for a specific patient Global traceability at the pharmacy of what was produced, when, how, by whomGlobal traceability at the pharmacy of what was produced, when, how, by whom 4.Administration of the medication to the patient

5 5 ©2010 University Hospitals of Geneva Two interesting phases At the pharmacy:At the pharmacy: Registration of what is being selected for the fabrication (“ingredients”, material)Registration of what is being selected for the fabrication (“ingredients”, material) Registration of what is being really used for the fabricationRegistration of what is being really used for the fabrication At the bed side:At the bed side: Validation of what is being administered to who, when and by whomValidation of what is being administered to who, when and by whom Registration of the different phases (start, stop, …)Registration of the different phases (start, stop, …)

6 6 ©2010 University Hospitals of Geneva Traceability at the pharmacy Several steps performed by different persons: Preparation of the set of ingredients to be used:Preparation of the set of ingredients to be used: Identification of the true vials (product, batch number)Identification of the true vials (product, batch number) Identification of the manufacturing kitIdentification of the manufacturing kit Manufacturing of the final product:Manufacturing of the final product: Identification of the substances at each step of the preparationIdentification of the substances at each step of the preparation Identification of the batch numbers at each step of the preparationIdentification of the batch numbers at each step of the preparation Quality control & traceability of what has been used, when and for which final productQuality control & traceability of what has been used, when and for which final product  Identification of each final product with a unique ID

10 10 ©2010 University Hospitals of Geneva What kind of unique Ids ? Unique IDs for various types of « objects »:Unique IDs for various types of « objects »: Medications, Vials of raw products, other materialMedications, Vials of raw products, other material Persons (patients)Persons (patients) Documents (prescription, …)Documents (prescription, …)  Selection of the GS1 Standard:  GTIN for products & vials (unique ID, batch number)  GTIN for locally produced medications (serial number, expiry date)  GSRN for patients  GDTI for documents  Datamatrix representation as the vehicle for the ID

11 11 ©2010 University Hospitals of Geneva GS1 codes: Cytostatic production Application: Application: HUG HUG cyt cyt :30: :30:00 GS1: (01) (7003) (21)cyt

13 13 ©2010 University Hospitals of Geneva Conclusion (1) GS1 standard proved to be adequate for the selected objects to identifyGS1 standard proved to be adequate for the selected objects to identify HUG GS1 codes for objects « belonging » to HUG:HUG GS1 codes for objects « belonging » to HUG: Manufactured medicationsManufactured medications PatientsPatients Documents produced by the clinical information systemDocuments produced by the clinical information system Lack of usable codes on vialsLack of usable codes on vials Not all vials and material with unique ID (product + batch number)Not all vials and material with unique ID (product + batch number) Temporary solution by re-encoding vialsTemporary solution by re-encoding vials

14 14 ©2010 University Hospitals of Geneva Conclusion (2) Centralized management of codes (encoding, decoding)Centralized management of codes (encoding, decoding)  Semantic & Rules at ONE single place  Easy to manage, maintain, modify, enhance Temporary:(01) (8009) (21)cyt Final:(01) (7003) (21)cyt GS1 codes = envelope on existing codesGS1 codes = envelope on existing codes  GS1 adds the semantic meaning to existing identifiers  No re-invention of identification codes
