Larsson B, et al. - This population study aimed to identify subgroups based on pain and psychological symptoms among Swedish older adults in the general population and compares derived subgroups with respect to socio-demographics, health aspects, and health care costs. The authors identified 2 high-risk clusters of older adults suffering from chronic pain; 1 mainly based on psychological symptoms and 1 mainly on pain intensity and pain spread, correlated with decreased quality of life and health and increased health care costs. The findings showed that subgroup-specific treatment would improve pain management and reduce health care costs.
