Impact of opioid dose reduction on individuals with chronic pain: results of an online survey.

Abstract

BackgroundIn 2016, the Centers for Disease Control and Prevention (CDC) released a guideline on opioid prescribing for primary care physicians. Patients with chronic pain receiving long-term opioid therapy were surveyed to assess the incidence and impact of opioid dose reduction following this guideline’s promulgation.MethodsMembers of an advocacy organization for people with chronic pain were invited to participate in a 16-item, anonymous, online survey conducted in September/October 2017. Eligibility requirements included current treatment of ≥7 months’ duration for chronic pain with the same extended-release (ER)/long-acting (LA) opioid. The final sample consisted of respondents who reported being on the same ER/LA opioid for ≥1 year and excluded respondents whose 1) ER/LA opioid dose increased; 2) ER/LA opioid dose decreased and immediate-release (IR) opioid dose increased; and 3) ER/LA opioid dose was unchanged and IR opioid dose was changed. Survey results were analyzed using z-test to ascertain differences between proportion of responses for ER/LA opioid dose decreased vs dose unchanged groups.ResultsOf the 511 eligible respondents, 362 respondents were included in the final sample. In the final sample, the subgroup with decreased ER/LA opioid dose (n=149) was significantly more likely (P≤ 0.05) than those who reported no dose change (n=213) to rate their condition as “worse” for level of pain (73.2 vs 33.3%), level of function (67.8 vs 31.5%), mental health (64.4 vs 32.9%), ability to work (62.9% of 97 respondents vs 33.8% of 145 respondents), and interpersonal relationships (48.3 vs 25.8%) during the previous 6 months.ConclusionIn this Internet-based survey of people with chronic pain, reduction of ER/LA opioid dose was associated with reduced pain control and diminished function. These results indicate a need for further guidance on how to apply the CDC guideline to patients with chronic pain who are stable on long-term opioid therapy.
