Background: Pain is common in patients with chronic liver disease. Our limited understanding of patterns and severity of pain in this population hinders the development of effective cirrhosis-specific pain management strategies.
Methods: Using cross-sectional data from the 2016-2021 National Health Interview Survey, we examined rates, severity, and functional limitations due to pain in respondents with liver disease (viral hepatitis, cirrhosis, and liver cancer), compared to the general population and those with other chronic conditions associated with pain (ie, arthritis, diabetes, and chronic kidney disease). Categorical and continuous variables were compared using χ2 and t test. Multivariable logistic regression was used to determine the predictors associated with pain and opioid use.
Results: Our liver disease cohort comprised 5267 participants (63% viral hepatitis, 49% cirrhosis, and 2% liver cancer). Participants with liver disease were more likely to report pain than those without liver disease (42% vs. 22%); they were also more likely to report severe pain (42% vs. 30%) and functional limitations by pain (28% vs. 13%) (p < 0.001 for all). On multivariable logistic regression, liver disease is an independent predictor of pain (OR: 2.31, 95% CI: 2.05-2.59, p < 0.001), even after adjustment for demographic factors. Liver disease respondents had similar rates of pain as those with diabetes (p = 0.8) and were more functionally limited by pain than those with arthritis (p < 0.001). Adjusted for demographic and pain-related factors, liver disease was also an independent predictor of chronic opioid use (OR: 1.47, 95% CI: 1.12-1.92, p = 0.0054).
Conclusions: Liver disease independently increases the likelihood of experiencing widespread and debilitating pain. Clinicians should consider liver disease a painful condition, ensuring that they are frequently assessing and appropriately treating pain in all liver disease patients.
