BACKGROUND:There is no commonly accepted comprehensive framework for describing the practical specifics of external support for practice change. Our goal was to develop such a taxonomy that could be used by both external groups or researchers and health care leaders. METHODS:The leaders of 8 grants from Agency for Research and Quality for the EvidenceNOW study of improving cardiovascular preventive services in over 1500 primary care practices nationwide worked collaboratively over 18 months to develop descriptions of key domains that might comprehensively characterize any external support intervention. Combining literature reviews with our practical experiences in this initiative and past work, we aimed to define these domains and recommend measures for them. RESULTS:The taxonomy includes 1 domain to specify the conceptual model(s) on which an intervention is built and another to specify the types of support strategies used. Another 5 domains provide specifics about the dose/mode of that support, the types of change process and care process changes that are encouraged, and the degree to which the strategies are prescriptive and standardized. A model was created to illustrate how the domains fit together and how they would respond to practice needs and reactions. CONCLUSIONS:This taxonomy and its use in more consistently documenting and characterizing external support interventions should facilitate communication and synergies between 3 areas (quality improvement, practice change research, and implementation science) that have historically tended to work independently. The taxonomy was designed to be as useful for practices or health systems managing change as it is for research.

Importance/UNASSIGNED:Secondhand smoke (SHS) exposure is associated with many health conditions in children and adults. Millions of individuals in the US are currently exposed to SHS in their homes. Objective/UNASSIGNED:To investigate whether a federal ban on smoking in public housing settings was associated with a decrease in indoor SHS levels in New York City public housing developments 12 months after the policy's implementation. Design, Setting, and Participants/UNASSIGNED:This cohort study tracked indoor air quality longitudinally from April 2018 to September 2019 and used difference-in-differences analysis to examine SHS exposure before vs after implementation of the 2018 federal smoke-free housing (SFH) policy in 10 New York City Housing Authority (NYCHA) buildings vs 11 matched low-income buildings not subject to the SFH policy (ie, Section 8 buildings). Exposures/UNASSIGNED:Federal SFH policy implementation, beginning July 30, 2018. Main Outcomes and Measures/UNASSIGNED:Comparison of nicotine concentration levels from passive, bisulfate-coated filters before vs 12 months after implementation of the federal SFH policy. Secondary outcomes included changes in particulate matter less than 2.5 μm in diameter, measured with low-cost particle monitors, and counts of cigarette butts in common areas. Results/UNASSIGNED:Air quality was measured repeatedly in a total of 153 NYCHA and 110 Section 8 nonsmoking households as well as in 91 stairwells and hallways. Before the SFH policy implementation, air nicotine was detectable in 19 of 20 stairwells (95.0%) in NYCHA buildings and 15 of 19 stairwells (78.9%) in Section 8 buildings (P = .19) and in 17 of 19 hallways (89.5%) in NYCHA buildings and 14 of 23 hallways (60.9%) in Section 8 buildings (P = .004). Nicotine was detected less frequently inside nonsmoking apartments overall (26 of 263 [9.9%]) but more frequently in NYCHA apartments (20 of 153 [13.1%]) than in Section 8 apartments (6 of 110 [5.5%]) (P = .04). One year after policy implementation, there was no differential change over time in nicotine concentrations measured in stairwells (DID, 0.03 μg/m3; 95% CI, -0.99 to 1.06 μg/m3) or inside nonsmoking households (DID, -0.04 μg/m3; 95% CI, -0.24 to 0.15 μg/m3). Larger decreases in nicotine concentration were found in NYCHA hallways than in Section 8 hallways (DID, -0.43 μg/m3; 95% CI, -1.26 to 0.40 μg/m3). Conclusions and Relevance/UNASSIGNED:The findings suggest that there was no differential change in SHS in NYCHA buildings 12 months after SFH policy implementation. Additional support may be needed to ensure adherence to SFH policies.

STUDY OBJECTIVE/OBJECTIVE:Housing instability is prevalent among emergency department (ED) patients and is known to adversely affect health. We aim to determine the incidence and timing of homeless shelter entry after an ED visit among patients who are not currently homeless. METHODS:We conducted a random-sample survey of ED patients at an urban public hospital from November 2016 to September 2017. Patients provided identifying information and gave informed consent for us to link their survey data with the New York City Department of Homeless Services shelter database. Shelter use was followed prospectively for 12 months after the baseline ED visit. We examined timing of shelter entry in the 12 months after the ED visit, excluding patients who were homeless at baseline. RESULTS:Of 1,929 unique study participants who were not currently homeless, 96 (5.0%) entered a shelter within 12 months of their baseline ED visit. Much of the shelter entry occurred in the first month after the ED visit, with continued yet slower rates of entry in subsequent months. Patients in our sample who entered a shelter were predominantly men and non-Hispanic black, and commonly had past shelter and frequent ED use. CONCLUSION/CONCLUSIONS:In this single-center study, 5.0% of urban ED patients who were not currently homeless entered a homeless shelter within the year after their ED visit. Particularly if replicated elsewhere, this finding suggests that ED patients may benefit from efforts to identify housing instability and direct them to homelessness prevention programs.

Few studies have assessed the fidelity of practice facilitation (PF) as an implementation strategy, and none have used an a priori definition or conceptual framework of fidelity to guide fidelity assessment. The authors adapted the Conceptual Framework for Implementation Fidelity to guide fidelity assessment in HealthyHearts NYC, an intervention that used PF to improve adoption of cardiovascular disease evidence-based guidelines in primary care practices. Data from a web-based tracking system of 257 practices measured fidelity using 4 categories: frequency, duration, content, and coverage. Almost all (94.2%) practices received at least the required 13 PF visits. Facilitators spent on average 26.3 hours at each site. Most practices (95.7%) completed all Task List items, and 71.2% were educated on all Chronic Care Model strategies. The majority (65.8%) received full coverage. This study provides a model that practice managers and implementers can use to evaluate fidelity of PF, and potentially other implementation strategies.

HealthyHearts New York City (HHNYC), one of 7 cooperatives funded through the Agency for Healthcare Research and Quality's EvidenceNOW initiative, evaluated the impact of practice facilitation on implementation of the Million Hearts guidelines for cardiovascular disease prevention and treatment. Tracking the intervention required a system to facilitate process data collection that was also user-friendly and flexible. Coupled with protocols and training, a strategically planned and customizable customer relationship management system (CRMS) was implemented to support the quality improvement intervention with 257 small independent practices. Features of the CRMS and implementation protocols were customized to optimize program management, practice facilitation tracking and supervision, and data collection for performance feedback to practices and research. The CRMS was a valuable tool for tracking and managing the intervention systematically. Successful implementation of the HHNYC protocol also required an articulated implementation plan and adoption process.

BACKGROUND:Effective strategies are needed to increase implementation and sustainability of evidence-based tobacco dependence treatment (TDT) in public health systems in low- and middle-income countries (LMICs). Our two-arm cluster randomized controlled trial (VQuit) found that a multicomponent implementation strategy was effective in increasing provider adherence to TDT guidelines in commune health center (CHCs) in Vietnam. In this paper, we present findings from a post-implementation qualitative assessment of factors influencing effective implementation and program sustainability. METHODS:We conducted semi-structured qualitative interviews (n = 52) with 13 CHC medical directors (i.e., physicians), 25 CHC health care providers (e.g., nurses), and 14 village health workers (VHWs) in 13 study sites. Interviews were transcribed and translated into English. Two qualitative researchers used both deductive (guided by the Consolidated Framework for Implementation Research) and inductive approaches to analysis. RESULTS:Facilitators of effective implementing of TDT included training and point-of-service tools (e.g., desktop chart with prompts for offering brief counseling) that increased knowledge and self-efficacy, patient demand for TDT, and a referral system, available in arm 2, which reduced the provider burden by shifting more intensive cessation counseling to a trained VHW. The primary challenges to sustainability were competing priorities that are driven by the Ministry of Health and may result in fewer resources for TDT compared with other health programs. However, providers and VHWs suggested several options for adapting the intervention and implementation strategies to address challenges and increasing engagement of local government committees and other sectors to sustain gains. CONCLUSION/CONCLUSIONS:Our findings offer insights into how a multicomponent implementation strategy influenced changes in the delivery of evidence-based TDT. In addition, the results illustrate the dynamic interplay between barriers and facilitators for sustaining TDT at the policy and community/practice level, particularly in the context of centralized public health systems like Vietnam's. Sustaining gains in practice improvement and clinical outcomes will require strategies that include ongoing engagement with policymakers and other stakeholders at the national and local level, and planning for adaptations and subsequent resource allocations in order to meet the World Health Organization's goals promoting access to effective treatment for all tobacco users.

BACKGROUND:Most hookah use studies have not included racial and ethnic minorities which limits our understanding of its use among these growing populations. This study aimed to investigate the individual characteristics of hookah use patterns and associated risk behaviors among an ethnically diverse sample of college students. METHODS:A cross-sectional survey of 2460 students (aged 18-25) was conducted in 2015, and data was analyzed in 2017. Descriptive statistics were used to present the sociodemographic characteristics, hookah use-related behavior, and binge drinking and marijuana use according to the current hookah use group, including never, exclusive, dual/poly hookah use. Multivariate logistic regression was conducted to examine how hookah related behavior and other risk behaviors varied by sociodemographics and hookah use patterns. RESULTS:Among current hookah users (n = 312), 70% were exclusive hookah users and 30% were dual/poly hookah users. There were no statistically significant differences in sociodemographic characteristics except for race/ethnicity (p < 0.05). Almost half (44%) of the exclusive hookah users reported having at least five friends who also used hookah, compared to 30% in the dual/poly use group. Exclusive users were less likely to report past year binge drinking (17%) and past year marijuana use (25%) compared to those in the dual/poly use group (44 and 48% respectively); p < 0.001. CONCLUSIONS:The socialization aspects of hookah smoking seem to be associated with its use patterns. Our study calls for multicomponent interventions designed to target poly tobacco use as well as other substance use that appears to be relatively common among hookah users.

Research Objective: Studies have found that race/ethnicity concordance between patients and providers improves medication adherence among patients with hypertension and single CVD outcomes (eg, blood pressure control). Our objective was to examine the association of patient-physician race/ethnicity concordance on adherence to the Million Hearts "ABCS" CVD guidelines: (A) aspirin when indicated, (B) blood pressure control, (C) cholesterol management, and (S) smoking screening and cessation. To the best of our knowledge, this is the first study to examine the impact of race/ ethnicity concordance on guideline adherence to multiple CVD outcome measures.
Study Design: This study was part of HealthyHearts NYC, a stepped-wedge cluster randomized controlled trial funded through AHRQ's EvidenceNOW initiative to test the effectiveness of practice facilitation on helping primary care practices adhere to CVD guidelines. The main outcomes were the Million Hearts' ABCS measures. Two additional measures were created: (a) proportion of patients who use tobacco who received a cessation intervention (smokers counseled) and (b) a composite measure that assessed the proportion of patients meeting treatment targets for A, B, and C (ABC composite). Practice-level outcome data were extracted for thirteen quarters from practices' electronic health record (EHR) systems, encompassing the control, intervention, and follow-up periods of the intervention. Patient-physician race/ethnicity concordance was calculated using patient race/ethnicity data extracted from the practices' EHR and physician race/ethnicity data collected via a Provider Survey. The concordance measure was calculated as the proportion of patients with the same race/ethnicity as the physician, for example, if practice is led by an Asian physician, and patients are 33% non-Hispanic white, 5% non-Hispanic black, 5% Hispanic, and 57% Asian, the concordance is 0.57. Population Studied: 211 small primary care practices in NYC. Principal Findings: 57.7% of Hispanic, 53.6% of black, 73.6% of Asian, 74.2% of non-Hispanic white, and 24.1% of Hawaiian/Pacific Islander patients had the same race/ethnicity as their physicians. 44.7% of physicians had the same race/ethnicity as at least 70% of their patients. Patient-physician race/ethnicity concordance was associated with adherence to four of our six outcome measures: aspirin (IRR = 1.08, 95% CI: 1.03-1.14, P < .001); blood pressure (IRR = 1.09, 95% CI: 1.07-1.12, P < .001); smoking screening and cessation (IRR = 1.06, 95% CI: 1.04-1.08, P < .001); and ABC composite (IRR = 1.42, 95% CI: 1.33-1.52, P < 0.001). We did not find an association for race/ethnicity concordance with Cholesterol and Smokers Counseled.
Conclusion(s): Increasing opportunities for patient-physician race/ ethnicity concordance may improve adherence to CVD guidelines. The largest improvement was observed in the ABC Composite measure, suggesting that patient-physician race/ethnicity concordance is particularly important for managing medically complex patients who have multiple chronic diseases. Implications for Policy or Practice: Health policy should fund programs that support the recruitment and retention of a wide diversity of students and faculty to increase the level of concordance in patient-clinician encounters. Policy makers may also want to consider legislation to help support or protect small practices that predominantly serve communities of color, where a large proportion of the physicians may be racially/ ethnically concordant with the patient population. Medical education programs should incorporate patient-physician communication training to minimize gaps potentially created by race/ethnicity discordance

OBJECTIVE:Understanding barriers and facilitators to engaging with implementation science (IS) research can provide insight into how to improve efforts to encourage more researchers to participate in IS research. STUDY DESIGN/METHODS:The study design used is a grounded theory qualitative study. METHODS:We conducted semistructured telephone interviews with 20 health researchers familiar with IS that both report engaging in IS research and those that do not. We explored perceptions of barriers and facilitators to engaging in IS research. Themes surrounding difficulties defining IS, lack of training availability, and obstacles to forming research partnerships were discussed as barriers to engaging IS research. Interview topics were informed by the result of an online survey of health researchers in the US. RESULTS:Themes surrounding difficulties defining IS, lack of training availability, and obstacles to forming research partnerships were discussed as barriers to engaging IS research. While accessible mentorship, exposure to formative experiences that develop interest in IS research and an increasing IS visibility were described as motivators for engaging in IS research. CONCLUSIONS:These results highlight the importance of mentorship and exposure to IS ideas in motivating engagement in IS research and the presence of training and methodological barriers to engagement. Future research should expand this line of inquiry to include the perspectives of more junior researchers and students to better reflect the current IS environment.
