U.S. primary care physicians' attitudes about medication for treatment of OUD.

Stratified analyses comparing survey results among early (waves 1 to 3) versus late (waves 4 to 6) responders showed overlapping 95% CIs for all items. Point estimates differed by less than 6 percentage points for all items, with 1 exception: 64.9% (95% CI, 58.7% to 70.7%) of early responders versus 54.0% (CI, 43.3% to 64.4%) of late responders reported that methadone is an effective treatment of OUD. Error bars represent 95% CIs. To create dichotomous measures for each domain, response categories 1 and 2 were combined. OUD = opioid use disorder.

* Used a 5-point Likert scale (1 = strongly agree; 2 = somewhat agree; 3 = neither agree nor disagree; 4 = somewhat disagree; 5 = strongly disagree).

† Used a 5-point Likert scale (1 = very interested; 2 = somewhat interested; 3 = neither interested nor uninterested; 4 = somewhat uninterested; 5 = very uninterested).

‡ Physicians indicated their current practices and future plans about prescribing medication to treat OUD by selecting from a list of options.

§ Used a 5-point Likert scale (1 = strongly favor; 2 = somewhat favor; 3 = neither favor nor oppose; 4 = somewhat oppose; 5 = strongly oppose). The item about the buprenorphine training and registration requirement had an additional option (6 = I am not familiar with this requirement).

∥ Used a 5-point Likert scale (1 = very important; 2 = somewhat important; 3 = neither important nor unimportant; 4 = somewhat unimportant; 5 = very unimportant).
