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

Background: In 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. Methods: Members 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 Eft/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. Results: Of 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. Conclusion: In 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.
