This study investigated the association between long-term opioid use and the risk of dementia in patients with chronic pain. The results showed that long-term opioid use may be associated with an increased risk of dementia. These findings highlight the need for cautious prescribing and monitoring of opioid use in this population.
Objective: This study aimed to investigate the association between long-term opioid use and the risk of dementia in patients with chronic pain. Design: A head-to-head propensity score-matched (PSM) comparative cohort study was conducted to examine the effect of long-term opioid use on dementia risk. A time-varying Cox regression analysis was performed to calculate adjusted hazard ratios (aHRs) with 95% CIs to identify independent predictors of dementia risk. Setting and Participants: The study included 41,636 patients after PSM, with 20,968 in the opioid use group (>= 180 defined daily doses per year) and 20,968 in the non-opioid use group. Methods: Multivariate Cox regression analysis was conducted to compare the dementia risk between the opioid use and non-opioid use groups. The incidence of dementia was calculated as the number of cases per 10,000 person-years for each group. Adjusted incidence ratios were determined to assess the dementia risk associated with opioid use. Results: The multivariate Cox regression analysis showed that the aHR for dementia risk in the opioid use group, compared with the non-opioid use group, was 1.86 (95% CI 1.25-2.09; P < .001). The incidence of dementia was higher among opioid users (44.09 per 10,000 person-years) compared with nonusers (38.85 per 10,000 person-years). The adjusted incidence ratio for dementia risk in the opioid use group, compared with the nonuse group, was 1.13 (95% CI: 1.07-1.21, P < .001). Conclusions and Implications: Long-term opioid use may be associated with an increased risk of dementia in patients with chronic pain. These findings highlight the need for cautious prescribing and monitoring of opioid use in this population, considering the potential long-term cognitive implications.
