Ulbricht CM, et al. - Researchers investigated the multidimensional nature of the non-malignant pain experienced by many nursing home residents in order to identify and describe pain symptom subgroups and to evaluate whether subgroups differed by sex. Analysis of newly admitted nursing home residents reporting pain (n=119,379) identified using Minimum Data Set 3.0 data (2011-2012), they identified four latent subgroups: Severe (15.2%), Moderate Frequent (26.4%), Moderate Occasional with (26.4%) and without (32.0%) Depressive Symptoms. Subgroups were distinguished by depressed mood, sleep disturbances, and fatigue. An inverse association of age ≥ 75 years was noted with belonging to the Severe, Moderate Frequent, or Moderate Occasional with Depressive Symptoms subgroups. In the Severe Pain subgroup and Moderate Frequent Pain subgroup, residents with severe cognitive impairment had reduced odds of membership, however, these had increased odds in the Moderate Occasional Pain with Depressive Symptoms subgroup. These findings emphasize the necessity to consider physical and psychological components of pain.
