To our knowledge, this is the first qualitative study to examine the cross-training needs of HIV and substance use disorder treatment clinicians. In general, both HIV and substance use clinicians desired additional cross-training in assessment and treatment. Although many of the clinicians reported some form of previous training on these topics, they noted that this training was provided a long time ago (e.g. in college or graduate training), occurred primarily “on the job” without formal instruction, and/or was monotonous. These findings about the low rates of cross-training are consistent with prior research documenting a need for more addiction-related curriculum, using interactive teaching methods, to be offered throughout medical training [19]. In recent years, some medical programs have begun to integrate buprenorphine waiver training into their curricula [20, 21], but the interplay of HIV and substance use risk still remains an area in need of focus.
In regards to areas of specific training need, both HIV and substance use clinicians discussed a need for sensitivity or anti-stigma training, as well as training in the latest medications and referral resources. In line with previous studies, some clinicians expressed that stigmatized behavior towards PLWH and people who use drugs could serve as a barrier to treatment retention [22–24]. Medications to treat opioid use disorder and medications to prevent/treat HIV were also cited as areas in need of further training. These findings are consistent with prior research indicating that insufficient knowledge of HIV, PrEP, and substance use disorder treatment options hinders linkage to appropriate treatment and integrated care for patients with comorbid HIV and substance use disorder [25].
The current results underscore the need for more formal cross-training opportunities in HIV and substance use. However, these trainings need to be carefully developed given that knowledge/skill gain in these topics may be a low priority for some practicing clinicians [16]. First, workforce training in integrated HIV and substance use care should begin in graduate training programs (e.g. in medical school, licensed substance use counseling programs) to build early knowledge about treatment best practice guidelines. Early training may be especially important, as clinicians face numerous barriers such as inability to bill for training time, high workplace productivity requirements, and low training availability once they begin practicing [12]. Second, training efforts should evaluate and prioritize areas of need, including screening and referral to treatment, identification of local HIV and substance use referral resources, and medications such as methadone and buprenorphine for opioid use disorder and PrEP and antiretroviral therapy for HIV [12]. Finally, both early and ongoing trainings should explicitly focus on stigma, and especially the intersectional stigma that may be experienced in healthcare settings by PLWH who use drugs [26, 27].
Our results also highlighted clinician preferences for training structure/format, including didactic workshops and ongoing supervision. Substance use disorder clinicians indicated a desire for an in-person workshop training far more frequently than HIV clinicians, suggesting that the ideal training strategies will likely differ by discipline. In general, clinicians expressed a desire for frequent HIV or substance use training delivered by skilled trainers. Training programs for substance use and HIV clinicians may need to incorporate strategies beyond traditional workshop training, as workshops are insufficient to promote behavior change [28] and were less preferred by HIV clinicians. Strategies such as incorporating active learning and behavioral rehearsal in training [29], and ongoing support activities such as supervision and performance feedback may be effective to enhance integrated care guideline uptake [30, 31]. Academic detailing strategies, or the provision of quick, personalized, one-on-one training in the clinician’s office [32], may also be particularly useful as it aligns with clinicians’ report of commonly learning “on the job.” Finally, all training and ongoing support strategies should incorporate intersectional stigma as a theme, including provision of stigma education, engagement with people with lived experience, and active learning opportunities to integrate destigmatizing practices (e.g. person first language; [26].
Study Limitations
The current findings must be considered within the context of several limitations. First, generalizability of the sample is limited by the focus on clinicians from New England, the majority of which were well educated with limited racial/ethnic diversity. It cannot be assumed that these results will be applicable to other regions. Second, this study was designed to focus on the provider perspective and, as such, did not consider the patient perspective. It is possible that patients would have different impressions of the areas of greatest training need in HIV and substance use treatment settings, and may offer unique views of intersectional stigma in healthcare. Finally, clinician feedback about their areas of greatest training need was likely limited by their familiarity with the discipline. Clinicians may have other areas of training need that did not emerge in these interviews due to limited provider awareness.
