Summary of Changes - this document summarises the updates to both the product and underlying design from the last Local Payment product release. Users are advised to read before using the latest Grouper.
Grouper User Manual - this document provides full instructions on how to prepare and group data using the updated HRG4+ Grouper software application, as well as illustrating how the revised product can be used to support users.
Chapter Summaries - this provides an overview of the scope, composition and grouping logic of individual subchapters, including the update to the new HRG design.
Code to Group - this workbook provides details of constituent elements that contribute to HRG grouping. It contains reference data, such as the ICD-10 and OPCS-4 codes used in the design, procedure and diagnosis hierarchies relevant to a specific design, and the Complication and Comorbidities lists for HRG subchapters. It also includes information on Programme Budgeting Category (PBC) mapping and comprehensive list of HRG codes.
Test data and expected results - these files provide sample data to test the Grouper installation (running the sample data should result in 90% grouped, 10% ungrouped). The file format of the sample data is representative of that in the default RDFs, provided within the Grouper application. These files can easily be used as example patient data, or as a template to understand the required input to the Grouper to enable successful grouping.
Casemix Companion - this document can now be found on our new web page The why, what and how of Casemix. This document is a starting point and general reference guide for anyone interested in learning about Casemix. It gives an introduction to HRGs, groupers, HRG4+ design concepts and grouping logic.
