BACKGROUND: Clinical guidelines recommend medications from four drug classes, collectively referred to as quadruple therapy, to improve outcomes for patients with heart failure with reduced ejection fraction (HFrEF). Wide gaps in uptake of these therapies persist across a range of settings. In this qualitative study, we identified determinants (i.e., barriers and facilitators) of quadruple therapy intensification, defined as prescribing a new class or increasing the dose of a currently prescribed medication. METHODS: We conducted interviews with physicians, nurse practitioners, physician assistants, and pharmacists working in primary care or cardiology settings in an integrated health system or federally qualified health centers (FQHCs). We report results with a conceptual model integrating two frameworks: (1) the Theory of Planned Behavior (TPB), which explains how personal attitudes, perception of others' attitudes, and perceived behavioral control influence intentions and behaviors; and (2) the Consolidated Framework for Implementation Research (CFIR) 2.0 to understand how multi-level factors influence attitudes toward and intention to use quadruple therapy. RESULTS: Thirty-one clinicians, including 18 (58%) primary care and 13 (42%) cardiology clinicians, participated in the interviews. Eight (26%) participants were from FQHCs. A common facilitator in both settings was the belief in the importance of quadruple therapy. Common barriers included challenges presented by patient frailty, clinical inertia, and time constraints. In FQHCs, primary care comfort and ownership enhanced the intensification of quadruple therapy while limited access to and communication with cardiology specialists presented a barrier. Results are presented using a combined TPB-CFIR framework to help illustrate the potential impact of contextual factors on individual-level behaviors. CONCLUSIONS: Determinants of quadruple therapy intensification vary by clinician specialty and care setting. Future research should explore implementation strategies that address these determinants by specialty and setting to promote health equity.

The federal Ending the HIV Epidemic (EHE) initiative was created to reduce new US HIV infections, largely through pre-exposure prophylaxis and HIV treatments that reduce HIV transmissibility to zero. Behavioral health disorders (mental health and substance use) remain significant barriers to achieving EHE goals. Addressing behavioral health (BH) disorders within HIV primary care settings has been promoted as a critical EHE strategy. Implementation of efficacious HIV-BH care integration and its impact on HIV-related health outcomes is not well documented. In a federally-funded, exploratory phase implementation science study, we used the Collective Impact Framework to engage partners in seven EHE jurisdictions about the feasibility, acceptability, and sustainability of implementing HIV-BH integration interventions within local HIV settings. Partners concluded that full integration will remain the exception unless health systems invest in collaborative practice, professional training, appropriate health technology, and inter-system communication. Partners supported smaller incremental improvements including transdiagnostic approaches to reinforce each team member's sense of value in the shared endeavor. This early phase implementation science study identified research and implementation gaps that are critical to fill to end the HIV epidemic. Both the Collective Impact Framework and implementation science show promise for guiding future implementation of evidence-based HIV-BH intervention integration.

BACKGROUND: Integrated care attempts to address multiple care needs, but barriers to implementation remain. The service user perspective can guide policy and practice to advance implementation. OBJECTIVE: To map barriers and facilitators to integrated primary care from the perspective of people with chronic conditions and multiple care needs. METHODS: A scoping review was conducted by searching PubMed, Embase, Web of Science, CINAHL, and grey literature. Eligible studies were analysed by categorising barriers and facilitators at the micro, meso, and macro levels of the healthcare system. They were further mapped by the components retrieved from the SELFIE framework for integrated care for multimorbidity. RESULTS: Across the 34 included studies, people with multiple care needs identified more barriers and facilitators at the micro level than at the meso and macro levels. Mapped under 'the individual and their environment', social and personal barriers (e.g. socioeconomic disadvantages, lack of social support) hindered integrated care. Mapped under 'service delivery' and 'workforce', a trusting relationship with a key care provider as part of a multidisciplinary care team was identified to facilitate integrated care. CONCLUSIONS: Our findings show that 'soft' relational and social factors are critical to integrated care. These 'soft' factors are primarily created at the micro level, but seem actionable at meso and macro levels. The unique perspective of people with multiple care needs suggests that more rigorous involvement of service users at higher levels is needed to inform policymakers and care providers on how to shape enabling conditions for the implementation of integrated care.
