Stimulant use for self-management of pain among safety-net patients with chronic non-cancer pain.
Stimulant use for self-management of pain among safety-net patients with chronic non-cancer pain. Substance abuse Beliveau, C. M., McMahan, V. M., Arenander, J., Angst, M. S., Kushel, M., Torres, A., Santos, G., Coffin, P. O. 2021: 1–8Abstract
BACKGROUND: Chronic pain affects one-fifth of US adults. Reductions in opioid prescribing have been associated with increased non-prescription opioid use and, chronologically, increased stimulant (methamphetamine and cocaine) use. While non-prescription opioid use is commonly attributed to pain self-management, the role of stimulants in managing pain is unclear.METHODS: We analyzed baseline data from a longitudinal study of patients with chronic non-cancer pain in an urban safety-net healthcare system who had been prescribed an opioid for =3 of the last 12months, and had a history of non-prescription opioid, cocaine, or amphetamine use (N=300). We estimated the prevalence and identified correlates of stimulant use to treat pain among a subgroup of patients who reported past-year stimulant use (N=105). Data sources included computer-assisted questionnaire (demographics, substance use, pain), clinical exam and procedures (pain, pain tolerance), and chart abstraction (opioid prescriptions). We conducted bivariate analyses to assess associations between demographics, pain characteristics, non-opioid therapies, substance use, opioid prescriptions, and self-reported symptoms, with reporting using stimulants to treat pain. Demographic variables and those with significant bivariate associations were included in a multivariable logistic regression model.RESULTS: Fifty-two percent of participants with past-year stimulant use reported using stimulants in the past year to treat pain. Participants who used stimulants for pain reported slightly higher average pain in the past 3months (median of 8 (IQR: 6-8) vs 7 (7-9) out of 10, p=0.049). In the multivariable analysis, female gender (AOR= 3.20, 95% CI: 1.06-9.63, p=0.039) and higher score on the Douleur Neuropathique 4 neuropathic pain questionnaire (AOR = 1.34, 95% CI: 1.05-1.70, p=0.017) were associated with past-year stimulant use to treat pain.CONCLUSION: Stimulants may be used for pain self-management, particularly for neuropathic pain and among women. Our findings suggest an underexplored motivation for stimulant use in an era of reduced access to prescribed opioids.
