Diabetes and its comorbidities are leading causes of morbidity and mortality in the United States and disproportionately in Louisiana. Chronic care management (CCM) efforts, such as care coordination models, are important initiatives in mitigating the impact of diabetes, such as poorer health outcomes and increased costs. This study examined one such effort, the Centers for Medicare & Medicaid Services' non–face-to-face CCM reimbursement program, for patients with diabetes and at least 1 other chronic condition in Louisiana. This qualitative study included interviews with patients in this program and health care providers and system leaders implementing the program. Results include lessons learned from health system leadership relating to CCM design and implementation, challenges experienced, overlapping initiatives, perceived benefits, performance, billing, and health information technology. Another key finding is that co-pays seem to be a barrier to patient interest in participation in non–face-to-face CCM, especially given that the value of the program is not completely clear to patients. A common strategy to address this co-pay barrier is to target dual eligibles, as Medicaid will cover the co-pay. However, widespread use of such strategies may indirectly exclude individuals who need and may also benefit from non–face-to-face CCM.

The burden of illness related to diabetes and its complications is exceedingly high and growing globally. Systematic approaches to managing chronic care are needed to address the complex nature of the disease, taking into account health system structures. This study presents data collected from interviews with physicians, health system administrators, and other healthcare staff about chronic care management for elderly people with diabetes co-morbid with other chronic conditions in light of new programs intended to reduce barriers by incentivizing care encounters that take place through telephone and electronic communications (non-face-to-face care). Results indicate that health system personnel view non-face-to-face care as potentially providing value for patients and addressing systemic needs, yet challenging to implement in practice. Barriers and facilitators to this approach for managing diabetes and chronic care management for its complications are presented, with consideration to different types of health systems, and recommendations are provided for implementation.

In 2016, California enacted a law (T21) prohibiting tobacco product sales to individuals under 21 years of age. Given tobacco use disparities among sexual minority (SM) youth, this study investigated whether California’s T21 law was differentially associated with changes in tobacco use for SM and non-SM adolescents. Secondary analyses of California Healthy Kids Survey data from 2013–2014 to 2018–2019 for 7th, 9th, and 11th graders (N = 2 229 401). Multilevel mixed-effects logistic regression analyses showed that SM students were more likely than non-SM students to report past-30-day and lifetime cigarette (odds ratio (OR) = 2.47; OR = 2.37), e-cigarette (OR = 1.21; OR = 1.10), smokeless tobacco use (OR = 1.95; OR = 1.56), and use of any tobacco product (OR = 1.94; OR = 1.61). Among SM youth, T21 was associated with significant reductions in lifetime e-cigarette use (OR = 0.66), and lifetime use of any tobacco products (OR = 0.75). These decreases generally were greater than or equivalent to those observed for non-SM youth. For 30-day e-cigarette and any tobacco use, SM youth showed no significant increases, whereas non-SM youth showed significant increases (OR = 1.06; OR = 1.11) following T21. T21 was associated with smaller increases in lifetime cigarette use (OR = 1.34), and larger increases for past-30-day and lifetime smokeless tobacco use (OR = 1.34; OR = 1.28) among SM students, to those observed for non-SM students. California’s T21 policy may help reduce tobacco use disparities among SM students who are more at risk for tobacco use than their non-SM peers. Research on associations of T21 laws with tobacco use among sexual minority (SM) adolescents is lacking. The potential for unintended consequences of T21 for these adolescents raises concerns about increased health disparities. Importantly, our study generally found California’s T21 was associated with reductions in tobacco use among SM students that were equivalent to or greater than those for non-SM students. Future research should investigate whether T21 laws and similar policies have differential effects for other marginalized groups and, if so, identify mechanisms that can be targeted in prevention efforts.

Context: Public health accreditation is an ongoing national movement to improve the quality of public health departments and the public health system in the United States; however, calls have been made for more evidence regarding best practices in the accreditation process. Objective: The purpose of this work is to provide evidence about best practices in the accreditation process, specifically within the workforce development domain. It is the first in-depth investigation into workforce development using data collected by Public Health Accreditation Board (PHAB). Design: Using deidentified accreditation application data from PHAB, this study employs a mixed-methods approach to examining practices, lessons learned, challenges, and strategies pertaining to workforce development planning for Domain 8. Setting: United States. Participants: US state (n = 19) and local health departments (n = 115). Main Outcome Measures: Public Health Accreditation Board assessment scores for the workforce measures and the relationship between the health department's approach to meeting a PHAB measure criteria and the PHAB assessment score. Results: Of the 9 different approaches identified as ways of encouraging the development of a sufficient number of qualified public health workers (version 1, measure 8.1.1), only 1 approach (local health department internship programs with schools of public health; B = 0.25, P < .03) was significantly related to higher scores. An opportunity for improvement identified for measure 8.2.1 was that plans missing a clear identification of the gap between current staff competencies and staff needs were associated with a 0.88-point decrease in the 4-point score (P < .001). Conclusions: Findings suggest that there are approaches adopted for meeting PHAB domain 8 measures that will impact the overall conformance assessment and score of a health department pursuing accreditation. There are several opportunities for improvement that health departments might consider when planning for accreditation or assessing their activities.

Background: Management of diabetes may be uniquely challenging for older individuals with multiple chronic conditions. Health systems and policymakers have attempted to reduce barriers to chronic care management (CCM) through incentives to provide non-face-to-face care. This qualitative study aimed to investigate and present views on non-face-to-face care management held by elderly patients with diabetes and other chronic conditions in order to contribute to improved programming for this population. Materials and methods: Semi-structured interviews were conducted with patients over the age of 64 who have been diagnosed with diabetes and at least one other chronic health condition. Interview recordings were transcribed and analyzed by experienced researchers using a thematic analytic approach, and an illustrative case study was developed. Results: Thirty individuals participated in this study. Participants were drawn from three health systems in south Louisiana, an area with high rates of morbidity and mortality related to chronic diseases. We identified themes related to lived experiences with diabetes and other medical conditions, perception of personal health status, perceived value of non-face-to-face programs, and support needs for future programming. Additionally, we present one case study describing in detail an individual patient’s experience with non-face-to-face CCM. Conclusion: Health systems should consider intentionally recruiting participants who would benefit most from non-face-to-face care, including higher-need, less self-sufficient patients with resource constraints, while continuing to offer in-person services. Future research should examine whether tailoring non-face-to-face programming and support to address unique barriers can further enhance diabetes care at the population level.

Chronic diseases impact 117 million adults in the United States and account for $3.3 trillion in health care spending. This qualitative study investigated experiences with reimbursement structure for non-face-to-face (NFF) chronic care management (CCM) through diverse health system approaches in primary care settings in Southeastern Louisiana. In-depth interviews were conducted with 16 purposively selected key informants, and reflexive thematic analysis was utilized to explore findings. Variation in health system approaches for implementing and quality of NFF CCM programs were identified. Results included differences in health system motivation and methods for financial structuring and quality of third-party vendor and alternative models.
