Characteristics of pharmacological pain treatment in older nursing home residents.

Abstract

Background: Pain in older subjects with cognitive impairement is frequently undertreated.Purpose: The aim of the study was to characterize pain treatment among 199 elderly nursing home residents (NHR), aged 65 years and above.Patients and methods: In all studied subjects, cognitive functions were assessed. Based on the results, participants were divided into two groups: group 1 – cognitively intact subjects in whom the pain was evaluated based on Numerical Rating Scale (NRS), and group 2 – subjects with cognitive impairment, in whom Abbey Pain Scale (APS) was used to assess pain. Thereafter, subjects with inappropriately treated pain (ie, ineffectively treated or untreated) were analyzed in detail as group 1a (NRS >0) and group 2a (Abbey >2).Results: The prevalence of pain in group 1 and 2 did not differ (65% and 70% respectively). However, inappropriately treated pain occurred more frequently in group 2 (2a=85% vs 1a=64%; p<0.01). This was related to the more frequent occurrence of untreated pain (52% vs 22%; p<0.001), because the presence of ineffectively treated pain was comparable in both groups (34% vs 42%). Qualitative analysis of pharmacotherapy in subjects with inappropriately treated pain demonstrated that acetaminophen in low dosages was the most frequently consumed drug from the first step of the analgesic ladder (16 individuals), from the second step – a combination of tramadol and acetaminophen (8 individuals), and from the third step – buprenorphine was the only drug applied (6 individuals).Conclusion: Our study showed a high frequency of untreated or ineffectively treated pain in NHR, regardless of the cognitive status of studied subjects. However, these phenomena were particularly frequent in subjects with cognitive impairment. Thus, proper education of the staff is needed to increase their knowledge about both the pain assessment and its treatment.
