Abstract

Objectives

Methods

Results

Criterion validation (n=422) demonstrated total LMQ scores negatively correlated with TSQM scores for global satisfaction (r=-0.616); domain scores showed similar correlations: effectiveness (r=-0.628), side-effects (r=-0.597), practicalities (r=-0.529). Total LMQ score was negatively correlated with EQ VAS (r=-0.383) and showed weak/moderate relationships with individual EQ-5D-5L dimensions.

Conclusion

The LMQ-3 instrument has acceptable construct, criterion-related and known-groups validity, and is internally consistent as a measure of medicines burden, although reliability requires further confirmation. It could be used to measure the outcome of interventions designed to reduce the burden of polypharmacy.
