The fungibility of time in claims of efficiency: The case of making transmission of prescriptions electronic in English general practice.

This paper presents a study of the effects of the implementation of the NHS Electronic Prescription Service (EPS) on time spent on repeat prescribing in English general practice. EPS is a new network service for the electronic transmission of primary care prescriptions, principally between GP practices and community pharmacies. This service is promoted on the basis of the importance of safe and timely supply of medicines, and the level of medicines use by many patients with treatable chronic conditions. The service is also based on presumptions of significant time-savings and efficiency gains for general practices and GPs. Our objective was to assess the time-related changes (including time savings) conditioned by digital transmission of prescriptions, specifically for repeat prescribing activity in primary care practices.
