Background Tobacco, alcohol and opioid misuse are associated with substantial morbidity and mortality among people with HIV (PWH). Despite existence of evidence-based counseling and medications for addiction, these treatments are infrequently offered in HIV clinics. The Working with HIV clinics to adopt Addiction Treatment using Implementation Facilitation (WHAT-IF?) study was conducted to address this implementation challenge. The study's goals were to conduct a formative evaluation of barriers to and facilitators of implementing addiction treatment for PWH followed by an evaluation of the impact of Implementation Facilitation (IF) on promoting adoption of addiction treatments and clinical outcomes. Methods The study was conducted at four HIV clinics in the northeast United States, using a hybrid type 3 effectiveness-implementation stepped wedge design and guided by the Promoting Action on Research Implementation in Health Services Research (PARiHS) framework. A mixed-methods approach was used to identify evidence, context, and facilitation-related barriers to and facilitators of integration of addiction treatments into HIV clinics and to help tailor IF for each clinic. An evaluation was then conducted of the impact of IF on implementation outcomes, including provision of addiction treatment (primary outcome), organizational and clinician and staff readiness to adopt addiction treatment, and changes in organizational models of care used to deliver addiction treatment. The evaluation also included IF's impact on effectiveness outcomes, specifically HIV-related outcomes among patients eligible for addiction treatment. Conclusions Results will generate important information regarding the impact of IF as a reproducible strategy to promote addiction treatment in HIV clinics.

Globally, substance use disorders are common and contribute to significant morbidity and mortality among people with HIV (PWH). [1] [2] [3] Tobacco use disorder leads to more years of life lost than HIV, particularly among those who are receiving antiretroviral treatment. 4 Alcohol use disorder contributes to worse outcomes along the HIV care continuum and is independently associated with increased risk of liver disease, cardiovascular disease, and malignancies and sexual risk behaviors with ongoing HIV transmission. 3 Similarly, opioid use disorder is associated with poorer engagement in HIV care and viral suppression, overdose death, and risk behaviors. [5] [6] [7] Fortunately, effective evidence-based counseling and medication treatments (referred to as "addiction treatments") for each of these conditions are available, can be safely provided to PWH receiving antiretroviral therapy ( Table 1) , [8] [9] [10] [11] [12] [13] [14] and are recommended by clinical guidelines. 15 Importantly, patient health outcomes are better when addiction and HIV care are delivered in an integrated fashion. 14, 16, 17 To date, routine adoption of addiction treatments in HIV clinics has been inconsistent. [18] [19] [20] [21] This is due in part to patients who are ambivalent about substance use treatment, 22 but it is also a function of some clinicians who are hesitant to adopt addiction treatments because they have limited knowledge of and discomfort with these evidence-based practices. 23, 24 To address this urgent implementation gap, innovative, feasible, reproducible strategies that promote sustainable adoption are needed. Implementation Facilitation (IF), also known as "Practice Facilitation," may represent one solution. 25, 26 Endorsed by the Agency for Healthcare Research and Quality, 27 IF is defined as a "a multi-faceted process of enabling and supporting individuals, groups and organizations in their efforts to adopt and incorporate clinical innovations into J o u r n a l P r e -p r o o f Journal Pre-proof routine practices." The literature suggest that IF is an effective implementation strategy for promoting evidence-based practices that address chronic diseases. 25, 26 Whereas IF is actively being applied to promote specific addiction treatments in general medicine settings, 28,29 to our knowledge, it is has not yet been applied to promote addiction treatment in HIV clinics and with a simultaneous focus on three distinct substances. A strength of the IF approach is the inclusion of a formative evaluation. Defined as "a rigorous assessment process designed to identify potential and actual influences on the progress and effectiveness of implementation efforts," 30 the formative evaluation allows for tailoring and adaptation of IF activities to meet site-specific needs and acknowledges the role of contextual factors in promoting implementation of evidence-based practices. This may be particularly relevant for integration of addiction treatment into HIV clinics, where a variety of factors such as the substance, clinician expertise, and resources, may impact the best model for such care integration. For example, all clinicians may be interested and willing to provide addiction treatment on site to each of their patients; prefer to have a clinician who is already part of the clinical team serve as the "specialist", or decide that new expertise need to be brought into the clinic or that all patients should be referred elsewhere. 31 Notably, preferences may vary across substance and clinicians within a particular site or across sites and different team members may be involved. 32 Given this, we conducted the Working with HIV clinics to adopt Addiction Treatment using Implementation Facilitation (WHAT-IF?) study. Employing a hybrid type 3 effectivenessimplementation stepped wedge design, 33,34 the goals of this study were to first conduct a formative evaluation of barriers to and facilitators of implementation of addiction treatment grounded in the Promoting Action on Research Implementation in Health Services (PARiHS) J o u r n a l P r e -p r o o f Journal Pre-proof framework. 35 Defined as a "rigorous assessment process designed to identify potential and actual influence on the progress and effectiveness of implementation efforts," formative evaluation can be done at several stages during an implementation effort. For instance, preimplementation, the formative evaluation can be directly used to inform selection and tailoring of the site specific implementation efforts. 30 Our formative evaluation was guided by PARiHS, a widely applied framework that was specifically developed to understand the factors impacting implementation of evidence-based practices in clinical settings. 35, 36 Then, we evaluated the impact of IF on promoting adoption of addiction treatments (primary outcome); clinician and staff as well as organizational readiness to provide addiction treatment; a description of models for delivering addiction treatment; and clinical outcomes. Herein, we describe the rationale, aims, and study design of the WHAT-IF? study.

Funded by the National Institute on Drug Abuse (NIDA) as part of a dedicated initiative to promote integration of infectious diseases and substance use intervention services for individuals with HIV, 37 WHAT-IF? was a multi-site hybrid type 3 effectiveness-implementation study that used a stepped wedge design to randomly assign sites to the onset of study activities (i.e., IF) (Figure 1) . 33, 34 Consistent with a hybrid type 3 effectiveness-implementation design where evaluation emphasis is on delivery of the treatment rather than patient outcomes, 34 the primary outcome for this study was provision of addiction treatment, assessed using electronic health record (EHR) data upon completion of IF. Secondary outcomes included additional J o u r n a l P r e -p r o o f Journal Pre-proof implementation outcomes (clinician and staff as well as organizational readiness to provide addiction treatments; models of care) and patient-level effectiveness outcomes (antiretroviral regimen receipt; HIV viral suppression; VACS Index 2.0 scores; and retention in HIV care).

We focused on promoting addiction treatment to address tobacco, alcohol, and opioid use given their prevalence and adverse impact on individuals with HIV and the existence of evidence-based counseling-as well as medication-based treatment options to address use of these substances that are recommended by clinical guidelines and can be provided in HIV clinics.

A hybrid type 3 effectiveness-implementation approach was appropriate given the existing evidence and clinical guidance supporting the use of addiction treatment among PWH and our interest in primarily evaluating the impact of the implementation strategy on practice change. In a stepped wedge design, a variation of a cluster randomized trial, clusters (namely, clinics in this study) are randomly assigned to the time at which they receive the intervention. 33, [38] [39] [40] This approach was chosen for this study as it: 1) allows all sites to receive the intervention, which is important when there is lack of clinical equipoise and it is desirable for all study units to receive the intervention; 2) facilitates conduct of the study related to logistical and personnel challenges with a small team of investigators leading the IF; and 3) allows for consideration of temporal trends, which is particularly relevant given the heightened focus on the opioid epidemic. 33 J o u r n a l P r e -p r o o f

We chose IF as the implementation strategy for several reasons. First, it is an effective implementation strategy (typically including audit and feedback; goal setting; system-level change; and collaborative meetings) for promoting evidence-based practices to address chronic diseases in clinical settings. 25, 26 To our knowledge, however, only few studies have applied IF or its components to promoting adoption of substance use disorder treatment 29, [41] [42] [43] and in a pilot fashion. 44 Second, given limited clinician training and potentially stigmatizing attitudes associated with addiction and existence of systems which have traditionally siloed addiction treatment into specialty settings outside of routine medical care, we believed stakeholder engagement would be particularly important. A strength of IF is that stakeholder engagement, including through the conduct of the formative evaluation, is inherent to the approach. Third, IF allows for flexibility such that different approaches to promote delivery of a given evidencebased practice may be adapted; given the variable contexts of our participating sites and desire to enhance generalizability to a range of settings, IF was deemed an appropriate implementation strategy. Fourth, we believed that a multi-pronged approach would be required that included more intensive engagement during the IF phase, that then tapered during evaluation and maintenance phases with the ongoing Learning Collaborative. Last, members of our team had experience with IF components. 32, [45] [46] [47] To guide our approach, we chose the PARiHS framework, which has identified three core elements for determining whether an evidence-based practice will be successfully implemented into clinical care: 1) the nature of the evidence (e.g., research, clinical experience) and key stakeholder's perceptions of that evidence; 2) qualities of the context in which the evidence is being introduced and enacted upon; and 3) the facilitation (i.e., implementation intervention), the strategy used to make it J o u r n a l P r e -p r o o f easier for both individuals and an organization to adopt a practice. 35, 36 It is therefore a usual framework for guiding qualitative work to understand barriers and facilitators to implementation of a given evidence-based practice 35 and also has been applied to guide the development of the Organizational Readiness to Change Assessment (ORCA), a quantitative assessment of organizational readiness to adopt a given evidence-based practice. 48 

The study was conducted in the context of the Yale's Center for Interdisciplinary

Research on AIDS (CIRA)-supported New England HIV Implementation Science Network, whose settings, but vary in terms of their affiliations (e.g., academic vs. community-based hospital clinic), infrastructure (e.g., on-site behavioral health), and resources (e.g., external grant funding). All sites rely on an EHR. The study was approved by the Institutional Review Boards at Yale University and at each of the participating universities and healthcare sites.

The study included two distinct participant groups who contributed both quantitative and qualitative data to the study: 1) clinicians and staff and 2) PWH actively receiving care at the participating clinics.

All clinicians, including prescribing (i.e., physicians, nurse practitioners, physician assistants) and non-prescribing clinicians (e.g., psychologists, social workers), as well as staff (e.g., nurses, community health workers) who had been employed at the given site for at least six months, were invited to participate in qualitative and quantitative data collection. We purposefully sought to elicit perspectives of diverse clinicians and staff given that 1) teambased multidisciplinary care is the norm in HIV clinics, 2) perspectives across clinicians and staff regarding addiction treatment could impact implementation of that treatment, and 3) different disciplines could serve a role in optimizing addiction treatment depending on resources and the context. Clinicians and staff were provided a meal and received a $50 gift card for participation in a focus group. In addition, meals and/or restaurant gift cards were offered at some sites to incentivize survey completion.

At each of the four participating clinics, a sample of PWH who had a diagnosis of a tobacco, alcohol and/or opioid use disorder were invited to participate in a focus group. We In addition, we used EHR data on all PWH actively receiving care in the participating clinics from July 16, 2016 through July 25, 2020 who had been diagnosed with a tobacco, alcohol and/or opioid use disorder. Patients were identified as having HIV using the visit reason and international diagnostic codes (ICD-9 and ICD-10). Patients were considered to be actively receiving care at a participating site if they had a scheduled visit at the clinic during the time period of interest, regardless of whether they attended the visit. Patients were eligible to enter the cohort (i.e., open cohort design) at any point during the study period once they met inclusion criteria. We intended to be inclusive in considering a patient active in care given that patients may cycle in and out of care. 50,51

Due to the potential for contamination from a distinct NIDA-funded project at The Miriam Hospital Immunology Center, this site was assigned to receive IF last. However, that project was never initiated, thereby reducing concerns regarding potential contamination. The other three study clinics were randomized to the time at which they would begin IF by the YCAS. Members of the investigative team and study sites remained blinded to the sequence until approximately 6 weeks prior to the start of IF to allow for planning of site visits.

The PARiHS framework 35, 36 guided the quantitative and qualitative assessments.

Specifically, we assessed ratings and perspectives on the evidence for addiction treatments J o u r n a l P r e -p r o o f ("evidence"), the HIV clinical context for delivering such treatments ("context"), and support needs and efforts for promoting adoption of addiction treatments in HIV clinics ("facilitation").

At each site, a clinic director or medical director completed a Qualtrics TM survey at survey initiation and then every six months over the course of the 3.5 years for a total of seven surveys to provide information on their patients served and resources, particularly as it related to provision of addiction treatment. Survey items included assessed clinic volume, patient demographics and insurance status, estimated prevalence of substance use disorders, HIV viral suppression, and retention in care. In addition, we collected data on types and availability of different clinical expertise available in the clinic (e.g., addiction medicine, addiction psychiatry, clinicians certified to prescribe buprenorphine, social workers); availability of on-site and offsite treatments for tobacco, alcohol, and opioid use disorder (e.g., counseling, case management, harm reduction, addiction specialist, outreach services); associated processes for linking patients to treatment (e.g., patient education about community resources, written referral, appointment, navigation); and current model for delivering care for tobacco, alcohol and opioid use disorder (Appendix 1). For example, to assess the clinic's approach to providing treatment for opioid use disorder, the survey asks: "How would you describe your clinic's current approach to providing treatment for opioid use disorder?" where options include: 1.

"Each clinician treats both HIV and opioid use disorder in their own patient panel;" 2. "At least one clinician in our clinic provides onsite treatment of opioid use disorder for their own patients and other clinicians' patients," 3. "Specialists provide treatment of opioid use disorder onsite at our clinic, but do not provide HIV primary care for any patients," and 4. "Specialists J o u r n a l P r e -p r o o f provide treatment for opioid use disorder outside of our HIV clinic (e.g. by referral)." These options are intended to capture the spectrum of possible care integration, including on the clinician level, clinic level, or system level. We additionally assess availability of on-site and offsite services to address each substance (e.g., substance use counseling, case management, addiction specialist, outreach services) and referral mechanism to off-site services.

After being provided an introduction to the survey from their medical director, clinicians and staff were invited to complete a confidential, web-based survey collected via Qualtrics TM at the same time points as the site description survey (i.e., study initiation and every six months for a total of seven surveys) . Surveys are open for six weeks with weekly reminders. Surveys were timed to occur at the end of each 6-month period (Figure 1) and immediately prior to IFrelated activities commencing at a site newly starting the intervention. Prior to filling out the survey, individuals were provided information about the survey and its purpose; the decision to complete the survey was considered consent to study participation. Based on our prior experiences, 24,31,52,53 literature review, and initial pilot testing and refinement with our multidisciplinary team, the survey was developed and designed to assess: 1) demographics and expertise; 2) past 6-month and lifetime experiences with prescribing and/or referring patients for counseling and medications to address tobacco, alcohol and opioid use; 3) preferred model of care for addressing tobacco, alcohol and opioid use (e.g. all clinicians are trained to deliver treatment, on-site specialist is available for referral); 31 4) readiness to provide or refer patients for treatment assessed by a readiness ruler (where response anchors included 0=not ready, 10=ready and responses were dichotomized as 0-<7=least ready; >7-10=most ready); 29 and 5) J o u r n a l P r e -p r o o f ratings on the ORCA, which was adapted from the original measure 48 to focus on adoption of counseling and medications to address tobacco, alcohol, and opioid use in HIV clinics (Appendix 1). Grounded in the PARiHS framework, the ORCA has been used to evaluate and predict the impact of implementation interventions 54, 55 and was used by our team in an implementation study designed to promote buprenorphine initiation in Emergency Departments. 29 Participants were asked to rate 1) the "evidence" supporting each evidence-based practice, 2) the HIV clinic Culture. An additional item assesses Slack Resources to examine resources available to support practice change. Subscale response options also included "don't know" or "not applicable," which were recoded as "neither agree nor disagree" or "neither frequently nor infrequently" to allow computation of subscale scores. 56

Upon IF initiation at each site and to gain a deep understanding of and contextualize the quantitative data, we conducted two focus groups at each site including one with clinicians and staff and a second with patients. The goals of these focus groups were to understand the: 1) degree of implementation of addiction treatment; 2) determinants of the current practices; 3) J o u r n a l P r e -p r o o f potential barriers to and facilitators of practice change; and 4) feasibility of the planned WHAT-IF? IF activities. 30 Focus groups were led by physicians with expertise in internal medicine, psychiatry, addiction medicine, HIV, qualitative methods and implementation science and grand tour questions were informed by the PARiHS framework (Appendix 2). Participants also completed a brief demographic survey.

These focus groups were digitally recorded and transcribed. We used a rapid assessment process 57,58 to inform IF activities and summarize and share findings with the medical director. We then followed this by a more detailed directed content analysis, 59 whereby members of the investigative team independently reviewed each of the transcripts line by line to develop and refine the codebook and reach consensus on codes and thematic saturation. 60 After there was consensus on the codebook and assigned codes, one investigator reviewed all transcripts to confirm these codes were consistently applied to all transcripts and entered into NVivo software to facilitate data organization and retrieval. Themes were then generated based on coded quotations and discussion with the research team within the PARiHS framework.

Among active PWH, we extracted past 12-month data at baseline and then in 6-month intervals during the study period on demographics, diagnoses, receipt of counseling and medications, visit frequency, and Veterans Aging Cohort Study (VACS) Index 2.0 score 61 components based on data collected as part of routine clinical care. Demographics variables included: age, race, ethnicity, gender, first three digits of zip code (as a proxy for socioeconomic J o u r n a l P r e -p r o o f status and to keep data de-identified), and insurance status. Diagnostic variables included presence of substance use disorders and mental illness based on the problem list, encounter reason and ICD-9 and ICD-10 codes. 62 Counseling to address substance use was captured based on encounters with a clinician, social worker, or psychologist and included psychiatric and substance use assessments, individual and group psychotherapy, individual counseling, case management, crisis intervention, prolonged services, family services, and health and behavior education. 63 Medications included prescription for antiretroviral agents consistent with an active HIV treatment regimen 64 and medications to treat addiction ( Table 1 ) that may be provided through HIV clinics. We assumed medications were taken as prescribed and assessed medication coverage in a given 6-month interval by determining days supplied with a given prescription such that a single prescription could span two separate intervals. For injectable naltrexone, we assumed the medication was active for 30 days, and administered on schedule as prescribed. Visits included completed office and follow-up visits to the HIV clinic with a clinician. Health status measures, which were ascertained based on labs closest to baseline and the end of each 6-month interval, included HIV biomarkers (CD4 cell count, HIV viral load) and the VACS Index 2.0 score. 61 The VACS Index 2.0 scores is calculated based on HIV biomarkers and additionally white blood cell count, hemoglobin, aspartate aminotransferase, alanine aminotransferase, serum creatinine, hepatitis C virus (HCV) antibody and RNA, albumin and body mass index. 61 The VACS Index score is a validated measure of morbidity and mortality that is sensitive to changes in substance use and its treatment among PWH. 65,66

For the current study, we adapted an existing IF manual used to promote mental health treatment into primary care 67 (Appendix 3) , which we have since further adapted for promoting buprenorphine initiation in Emergency Departments. 29 IF included a bundle of activities designed to promote addiction treatment into HIV clinics tailored to site specific needs ( Table 2) . Informed by the survey data collected prior to IF initiation and information regarding the clinical organizational structure, IF activities began with a formative evaluation of barriers and facilitators to promoting addiction treatments in HIV clinics. This involved a full day site visit to each site during which initial focus groups were conducted with stakeholders, as well as a face-to-face meeting with the medical director, tour of the HIV clinic, review of workflow and electronic medical record documentation. These initial site visits were followed by two follow-up visits to each site during which academic detailing was conducted and efforts were made to bridge silos across disciplines (e.g., Addiction Psychiatry and/or Addiction Medicine and Infectious Disease) within the same institution. These visits were complemented by ongoing communications (via email, telephone) with the sites to facilitate additional IF activities. In addition, upon initiation of the IF period, sites were invited to join the Learning Collaborative activities, which extended for the duration of the study to support implementation efforts. Throughout the course of the study, we tracked conduct and participation in IF activities using a tracking log. 68 This included, for example, how many clinicians and staff received academic detailing; delivery of on-site lectures and journal clubs focused on addiction treatment; and timing and content of Learning Collaborative calls.

Consistent with the goals of a hybrid 3 effectiveness-implementation study, the primary goal of this study was to assess the impact of IF on provision of addiction treatment among eligible patients by the clinics over time (baseline vs. evaluation vs. maintenance periods).

Informed by prior work, we anticipated an 11% absolute increase during the evaluation phase and 19% absolute increase during the maintenance phase from baseline. A parallel group design, unadjusted for clustering and repeated measures would require a sample size of 592 (296 in each the control and intervention arms) to detect the estimated effect size assuming 90% power and Type I error of 0.05. To account for the stepped wedge design, we made the following assumptions: 1) each clinic would provide a minimum of 300 addiction treatment eligible patients; 2) intracluster correlation, =0.001; 3) number of steps, κ=4; 4) number of baseline measurements, b=1; and 5) number of measurements taken after each step, t=1. 69 This yielded a derived design effect of 0.63 and assuming a cross-sectional design, a required adjusted sample size of 375 across the four clinics.

The primary implementation outcome for this study was the change in the percentage of treatment eligible patients who received addiction treatment during the evaluation and maintenance periods compared to the baseline period.

Secondary implementation outcomes included ORCA and readiness rulers scores, each as continuous outcomes, and models of care used to deliver addiction treatment.

J o u r n a l P r e -p r o o f

We additionally evaluated the impact of IF on effectiveness (i.e., patient-level outcomes) among patients diagnosed with a tobacco, alcohol or opioid use disorder. Secondary outcomes included: prescription for an active antiretroviral regimen; HIV viral suppression, defined as an HIV RNA <200 copies/mL 15 ; VACS Index 2.0 score; and retention in HIV care, assessed by whether patients had at least one visit in a 6-month period. 70

Characteristics of patients and clinics will be shown by randomization status in each step of the design. For all analyses, we will use an intent-to-treat approach according to the time clinics were intended to cross over from control condition to IF. For the primary implementation outcome, we will use a generalized linear mixed model, adjusting for calendar time (a potential confounder due to its association with both exposure to the intervention and outcome), with a random effect for clinic, a fixed effect for each step and allowing for repeated measures for patients in the clinics. Since the population of the clinics participating in this study are generally stable, rendering this a cohort stepped wedge design, an additional random effect for patients in each clinic will be included. We will apply a similar approach to evaluate the impact of IF on ORCA subscale scores and readiness ruler scores. Additional analyses will be used to evaluate whether ORCA subscale scores mediated the proportion of treatment eligible patients receiving addiction treatment. 71 To determine the impact of IF on models of care, we will describe the extent to which provision of treatment for each substance is coordinated (facilitated by the clinic), co-located J o u r n a l P r e -p r o o f (provided in the clinic) or integrated (provided by the primary HIV clinician) by clinic. We will track changes in these models of care from the control period to the evaluation and maintenance periods.

We will examine each of the HIV-related secondary effectiveness outcomes at the 6month intervals of control, evaluation and maintenance phases based on the provision of addiction treatment. We will determine the association between provision of addiction treatment and effectiveness outcomes using the repeated measures MIXED models for continuous outcomes and generalized estimating equations for dichotomous outcomes. We will adjust for demographics, substance use disorder and psychiatric diagnoses. We will describe the associations with least squares means or odds ratios and 95% confidence intervals.

As of June 30, 2020, all sites are in the "maintenance phase" of the study. To date, there have been several unpredictable factors impacting study implementation. First, as above, due to a competing NIDA-funded study at one of the sites, we intentionally assigned this site to receive IF last to avoid contamination. Second, study timing overlapped with changes in the EHR; at one site, this occurred in the beginning of the study while in a second site, this occurred during the last period of the study with potential impact on how well diagnoses are captured. This may impact denominators (i.e., patients identified as eligible for addiction treatment) due to changes in charting practices and numerators (given the impact of EHR changes on clinical practice during the transition phase). Third, the novel coronavirus (COVID-19) resulted in a global pandemic beginning March, 2020 in the northeast United States. This has yielded J o u r n a l P r e -p r o o f substantial changes in the healthcare system, including decreased on-site clinic visits and the use of telehealth for routine HIV care. Since this event occurred toward the end of our study, we believe this threat to the validity of our findings will be minimal; however, we will conduct sensitivity analyses excluding the data that overlap with this time period. As of September 8, 2020, sites are finalizing extractions from the EHR for the final study period and efforts to disseminate findings (i.e., abstract submissions, manuscripts) are anticipated starting in 2021.

Strategies are needed to increase the provision of addiction treatment to address tobacco, alcohol and opioid misuse in HIV clinics. This protocol describes a novel application of IF to enhance delivering of treatments for unhealthy substance use for which there are both counseling and medication-based options that are suitable for delivery in HIV clinics. In addition, by using a hybrid type 3 effectiveness-implementation design, we will gain critical data regarding both the impact of IF on the clinic, clinician and staff, as well as on patients. Given the variability in the clinic structures, we will learn important lessons for implementation of addiction treatment in both academic and community-based settings.

There are several limitations to our protocol. First, we will be using electronic health record to assess adoption of counseling services to address opioid, alcohol, and tobacco use disorder, but will be limited in our ability to confirm that substance use was specifically addressed during these sessions. In secondary analyses, we will be able to evaluate the concordance between electronic medical record data and self-reported provision of counseling J o u r n a l P r e -p r o o f among clinicians and staff using the survey data. Second, while we focus on provision of addiction treatment as a primary outcome of this study; we did not evaluate how IF translates into quality of care. Future studies of IF and other implementation strategies, however, should focus on assessment of the quality of care that is provided. Third, findings from this study may not be generalizable to clinics located in other parts of the United States. Fourth, we may not be able to fully account for factors that may lead to disruptions in clinical care (e.g., EHR transition, clinic moves) and staffing changes. Fifth, based on our measurement of adoption, we will be unable to determine whether any observed gaps in provision of addiction treatment are driven by clinician or patient level factors. Lastly, given variable practices in screening for and documenting presence of substance use and substance use disorders, the denominators will likely be an underestimate of true prevalence.

The current study will provide much needed data on the impact of a reproducible, adaptable strategy for promoting treatment of tobacco, alcohol, and opioid misuse in HIV clinics. Given the profound individual and public health impacts of these conditions among PWH, solutions for promoting adoption of guideline-recommended care are urgently needed.
