OBJECTIVES: To determine if demographic and practice factors affect intention to prescribe buprenorphine for Texas Drug Addiction and Treatment Act (DATA 2000) waivered providers. METHODS: Qualtricsxm online survey instrument was developed based on a prior focus group study with Texas DATA 2000 waivered providers. A list of 1,000 providers were selected after merging the Drug Enforcement Administration (DEA) database with the physician’s database from the Texas Medical Board (TMB). Three rounds of postcards were sent to providers with the survey link. Multiple linear regression was used to analyze the impact of attitude, subjective norm, perceived behavioral control, demographic (e.g., age, gender and race) and practice factors (e.g., experience in years and practice location) on intention to prescribe buprenorphine. Independent t-tests were used to compare means of the theory of planned behavior constructs between the groups of providers. RESULTS: A total of 81 completed surveys were obtained. The included providers were 54 years of age or older (39.5%), white (67.9%) and male (69.1%), and had more than 16 years of practice experience (54.3%). Most participants were licensed to practice as Doctor of Medicine (MD) or Doctor of Osteopathic Medicine (DO) (92.5%). A total of 33% of the variance in intention was predicted by the variables of attitude, subjective norm, perceived behavioral control, gender, age, race, years of experience and practice location. Perceived behavioral control and gender were significantly associated with intention to prescribe buprenorphine. Significant difference in means was seen between perceived behavioral control for providers with, <5-15 years and 16+ years of age. CONCLUSIONS: Perceived behavioral control was associated with higher intention to prescribe buprenorphine. Interventions should be developed such that providers perceive more control over prescribing practices for buprenorphine. Steps are required to close the experience gaps between providers by encouraging peer support from experienced providers.
