Evaluation of a community pharmacy dispensing process using a Coloured Petri NetTools Naybour, M., Remenyte-Prescott, R. and Boyd, M. (2018) Evaluation of a community pharmacy dispensing process using a Coloured Petri Net. In: 28th International European Safety and Reliability Conference (ESREL 2018), 17-21 June 2018, Trondheim, Norway. (In Press) Full text not available from this repository.AbstractUK customers visited community pharmacies to receive NHS prescriptions 1.104 billion times in 2016. One study of dispensing errors found an error rate of 3.3%. Severe dispensing inaccuracies often receive a high level of media attention, however, lower level errors could also be causing significant inefficiencies in the delivery of primary healthcare. This paper presents a modelling approach for analysing the reliability and efficiency of community pharmacies performance using a Coloured Petri Net (CPN) methodology. The model consider show single prescriptions are processed, the use of staff resources, and the occurrence of errors. The CPN evaluates performance over a set of key performance indicators. Results are validated, where possible, against published studies of community pharmacies.
