Overview

Summary of dataset and variables

This dataset is based on items prescribed by any Welsh general practice staff member, qualified to prescribe, which are subsequently dispensed in the community in the UK. 'Items’ refer to each different medicine or appliance listed on a prescription regardless of quantity or volume. Only items which are dispensed are counted. Net ingredient cost, measured in pounds sterling, is the underlying cost of the item, before any additional fees (for example, dispensing fees to pharmacies) or discounts (NHS clawbacks) are applied. The British National Formulary (BNF) is a pharmaceutical reference book containing information and advice on prescribing. Every item prescribed is categorized by its BNF chapter. In 2024-25 there were 23 different chapters. A 'cluster' is a collaborative way of providing health services in Wales, which brings together services provided by general practices, other primary care services, district nurses, social services and the third sector Clusters are not based on exact geographic areas, but bring together neighbouring service providers.

Data collection or calculation

Prescriptions data are obtained from Prescribing Services, NHS Wales Shared Services Partnership and are based on information on prescription forms sent by the prescriber for payment. The Welsh Reference Data and Terminology Service (WRTS) in Digital Health and Care Wales are responsible for mainatining lists of clusters, with look ups to match each general practice to a cluster. Changes are infrequent, but cluster names and 'boundaries' can change over time. In addition, constituent general practices may move in and out of clusters.
