Topic: Risk, prevention and care in population studies
Background The Resource Utilization in Dementia (RUD) questionnaire is the most widely used instrument for resource use data collection in dementia, enabling comparison of costs of care across countries with differing health care provisions. Recent feedback from payers questioned its face validity given that health care provisions have changed since the initial development of the RUD in 1998. The aim of this study was to update the RUD to improve its face validity in Alzheimer's disease (AD) clinical research and its utility for health care resource allocation. Methods An extensive PubMed review was conducted of current relevant resource items in AD in 15 countries. The findings were complemented by interviews with local care providers and experts in dementia care and health economics. Their proposed revisions were discussed with five leading dementia experts in North and South America, northern and southern Europe, and Asia. A new version of the RUD was developed based on their recommendations. Results RUD users identified a need for more information relevant to coverage decisions. Proposed revisions included changes to existing questions (e.g., to capture more accurately the number and type of health care visits) and the addition of new questions (e.g., on informal caregiver hours and the primary caregiver's hours of sleep). Conclusion Several minor changes were made to the RUD instrument to improve the accuracy and precision of the data while maintaining comparability with the original version and reflecting current medical practice. The RUD Complete Version 4.0 is now available for use in future AD clinical trials.

Key findings
- Results RUD users identified a need for more information relevant to coverage decisions.
Why it matters
This study updated the Resource Utilization in Dementia questionnaire to improve its face validity for Alzheimer's disease clinical research and health care resource allocation. It is about a cost and resource measurement tool and does not test any treatment, cure, or prevention for Alzheimer's disease.
