Attitudinal Barriers to Analgesic Use among Patients with Substance Use Disorders

Abstract EN

Attitudinal barriers towards analgesic use among primary care patients with chronic pain and substance use disorders (SUDs) are not well understood.

We evaluated the prevalence of moderate to significant attitudinal barriers to analgesic use among 597 primary care patients with chronic pain and current analgesic use with 3 subscales from the Barriers Questionaire II: concern about side effects, fear of addiction, and worry about reporting pain to physicians.

Concern about side effects was a greater barrier for those with opioid use disorders (OUDs) and non-opioid SUDs than for those with no SUD (OR (95% CI): 2.30 (1.44–3.68), P<0.001 and 1.64 (1.02–2.65), P=0.041, resp.).

Fear of addiction was a greater barrier for those with OUDs as compared to those with non-opioid SUDs (OR (95% CI): 2.12 (1.04–4.30), P=0.038) and no SUD (OR (95% CI): 2.69 (1.44–5.03), P=0.002).

Conversely, participants with non-opioid SUDs reported lower levels of worry about reporting pain to physicians than those with no SUD (OR (95% CI): 0.43 (0.24–0.76), P=0.004).

Participants with OUDs reported higher levels of worry about reporting pain than those with non-opioid SUDs (OR (95% CI): 1.91 (1.01–3.60), P=0.045).

Concerns about side effects and fear of addiction can be barriers to analgesic use, moreso for people with SUDs and OUDs.
