pharmacies has a bright future, according to Paul Le Brun (Hospital pharmacist – clinical pharmacologist, Leiden University Medical Centre, The Netherlands). This is being driven by the increasing focus on patient safety, the demand for personalised medicine, the advent of complex medicines such as advanced therapy medicine products (ATMPs) and the emergence of new technologies such as robotics and 3D printing. Ready-to-use (RTU) and ready-to-administer (RTA) medicines are needed to avoid errors in reconstitution. These can arise because of calculation errors, procedural errors such as incomplete dissolution or use of the wrong diluent, incompatible administration devices or microbiological contamination. Dr Le Brun said that a risk-based approach should be used to determine where injections should be prepared and by whom. The European Resolution on good reconstitution practice (Resolution CM/Res (2016)2) sets out the requirements for safe reconstitution of injectable medicines. Among other provisions, healthcare establishments are expected to nominate a designated person, preferably a pharmacist, who is responsible for the management of good reconstitution throughout the organisation. Risk assessment of each product determines which products should be reconstituted where (that is, pharmacy or clinical area). In practice, more than 90% of reconstitutions are simple and can be carried out on wards (with suitable training and support); the remainder are complex and need to be carried out in the pharmacy. Ongoing risk management with regular reviews of risks is essential to improve safety on wards, explained Dr Le Brun. Personalised medicines for patients with shared disease markers would increasingly be used in future. At present everyone receives the same treatment; some patients benefit from it, some do not, and some experience adverse effects. In future, biomarker diagnostics would enable clinicians to select the right (that is, effective) treatment for each individual, he predicted. One of the challenges will be dealing with increasingly complex medicinal Further development of robotic technology for parenteral products will be important not only for efficiency, productivity and product quality but also for the safety and health of the staff involved products. For example whereas a paracetamol molecule has a diameter of about one nanometre (nm), monoclonal antibodies are about 10-times bigger and cells could be as big as 50 micrometres in diameter (50,000nm). In future, pharmacies will be expected to handle ATMPs. These may be gene therapy (GTMP), cell therapy (CTMP), tissue engineered products (TEP) or combined products. For gene and cell therapy, cells (for example, haematopoietic cells) are harvested from the patients, loaded with therapeutic genetic material in vitro and then infused back into the patient. A number of ATMPs have now received marketing authorisations, including Holoclar, a tissue-engineered product for limbal cell deficiency and Imlygic (talimogene laherparepvec) a GTMP for unresectable melanoma, noted Dr Le Brun. Special 46 | Issue 90 | 2018 | hospitalpharmacyeurope.com Ready-to-use (RTU) and ready- to-administer (RTA) medicines are needed to avoid errors in reconstitution facilities and expertise will be required to handle ATMPs. The raw materials could themselves be a source of risk and contaminant control will be challenging given that sterilisation by filtration is not an option and there can be no sterilisation of the final product. Furthermore there is unlikely to be any product-specific reference material (for final product testing) and the shelf-life may be hours or days if the product is not cryopreserved. Good Manufacturing Practice for ATMPs came into force in the European Union in May 2018. Further development of robotic technology for parenteral products is likely and this will be important not only for efficiency, productivity and product quality but also for the safety and health of the staff involved. Repetitive strain injuries and exposure to hazardous substances can be avoided by these means. Lastly, 3D printing of medicines is likely to become a reality. In fact, the first 3D-printed medicine – Spritam (levetiracetam) – has been approved by the FDA. In future, bioprinting (organs on chips, diagnostic tissue) and small-scale preparation of biologicals could follow, said Dr Le Brun. All of this means that the need for pharmaceutical expertise in the preparation of medicines will not diminish. Proper handling of the pharmaceutical product is part of clinical treatment, he emphasised. “Education is paramount. Now is the time to invest in skills and technology”, he concluded. Discharge management The implementation of a comprehensive discharge medication management system called for multidisciplinary input and cooperation, said Irene Kramer (Director of Pharmacy, University Hospital, Mainz, Germany). Hospitals in Germany were required by law to introduce a structured discharge management scheme by October 2017. The scheme makes use of the German national electronic medication record (see HPE 83), a measure that was developed to improve medication safety and reduce the number of medication-related problems that led to hospital admissions. The electronic record can be printed for patients but also contains all the information in a 2D-barcode that allows rapid transfer (by scanning) of accurate information when a patient is admitted to and discharged from hospital. Studies have shown that use of the medication record improves patient knowledge and reliable use of medicines, noted Professor Kramer. The present scheme requires active pharmaceutical management at the interface, she explained. At the time of admission, pharmacists scan the medication record to obtain a list of medicines and add to the record any medicines that are being used for self-treatment and any necessary changes are made to conform to the in-house formulary. A ‘medication analysis’ is also performed to check for interactions, dosing inconsistencies, etc. The electronic record is updated when changes are made and, at the time of discharge, the medication is explained and a printed copy of the up-to-date record is given to the patient. The 43rd scientific congress of the Bundesverband Deutscher Krankenhausapotheker (ADKA) took place in Stuttgart, Germany on 3–5 May 2018.
