An expanded chronic care management approach to multiple chronic conditions in Hispanics using community health workers as community extenders in the Rio Grande Valley of Texas.

INTRODUCTION: The synergistic negative effects of type 2 diabetes (T2DM) and hypertension increases all-cause mortality and the medical complexity of management, which disproportionately impact Hispanics who face barriers to healthcare access. The Salud y Vida intervention was delivered to Hispanic adults living along the Texas-Mexico Border with comorbid poorly controlled T2DM and hypertension. The Salud y Vida multicomponent intervention incorporated community health workers (CHWs) into an expanded chronic care management model to deliver home-based follow-up visits and provided community-based diabetes self-management education. METHODS: We conducted multivariable longitudinal analysis to examine the longitudinal intervention effect on reducing systolic and diastolic blood pressure among 3806 participants enrolled between 2013 and 2019. Participants were compared according to their program participation as either higher (≥ 10 combined educational classes and CHW visits) or lower engagement (<10 encounters). Data was collected between 2013 and 2020. RESULTS: Baseline mean systolic and diastolic blood pressure were 138 and 81 mmHg respectively. There were overall improvements in systolic (-6.49; 95% CI = [-7.13, -5.85]; p < 0.001) and diastolic blood pressure (-3.97; 95% CI = [-4.37, -3.56]; p < 0.001). The higher engagement group had greater systolic blood pressure reduction at 3 months (adjusted mean difference = -1.8 mmHg; 95% CI = [-3.2, -0.3]; p = 0.016) and at 15 month follow-up (adjusted mean difference = -2.3 mmHg; 95% CI = [-4.2, -0.39]; p = 0.0225) compared to the lower engagement group. CONCLUSION: This intervention, tested and delivered in a real-world setting, provides an example of how CHW integration into an expanded chronic care model can improve blood pressure outcomes for individuals with co-morbidities.

Participant engagement in a community health worker-delivered intervention and type 2 diabetes clinical outcomes: a quasiexperimental study in MexicanAmericans.

OBJECTIVES: This study helps to fill the existing research gap related to participant engagement in behavioural interventions and diabetes management. We examined type 2 diabetes control over time among Mexican Americans by level of engagement in a chronic care management (CCM) program that included community health worker (CHW)-delivered multilevel interventions. The programme complemented clinical care and promoted behaviour changes to improve diabetes self-management. DESIGN: Quasiexperimental study. SETTING: The study was implemented in the Rio Grande Valley region in the USA. Recruitment was conducted in clinics and community events. All other visits were provided in participant homes and community locations. PARTICIPANTS: 5649 adults (aged ≥18 years) with poorly controlled type 2 diabetes who enrolled in a community-delivered CCM programme between September 2013 and 2018. INTERVENTIONS: The intervention comprised two components: CHW home visits conducted every 3 months and diabetes self-management education (DSME) classes provided in community locations. PRIMARY OUTCOME MEASURES: The primary outcome was haemoglobin A1c (HbA1c) measured at baseline every 3 months for up to 24 months. We first examined changes in HbA1c levels over time. The number of completed CHW and DSME encounters was used to classify participants into engagement groups-high engagement defined as ≥10 encounters (n=2952); low engagement defined as 1-9 encounters (n=2697). We used univariable and multivariable longitudinal linear regression models with a generalised estimating equation method. We tested interactions between engagement groups and time. RESULTS: Participants' mean HbA1c decreased from 10.20% at baseline to 8.93% (p<0.0001) at 3 months, remaining stable thereafter. Changes in HbA1c were statistically different between the engagement groups. High engagement participants had lower HbA1c levels over the first 15 months of the follow-up period compared with low engagement participants, as compared at 3 months (-0.44%, 95% CI -0.57% to -0.31%; p<0.0001), 6 months (-0.31%, 95% CI -0.43% to -0.14%; p<0.0001), 9 months (-0.27%, 95% CI -0.42% to -0.13%; p=0.0001), 12 months (-0.23%, 95% CI -0.37% to -0.08%; p=0.0025) and 15 months (-0.32%, 95% CI -0.54% to -0.10%; p=0.0040). At months 18, 21 and 24, the HbA1c differences were not statistically significant (18 months: -0.34%, 95% CI -0.77% to 0.08%; p=0.1086; 21 months: -0.22%, 95% CI -1.00% to 0.56%; p=0.5721; 24 months: -0.42%, 95% CI -1.38% to 0.55%; p=0.3966). CONCLUSIONS: Higher engagement in the CCM programme delivered by CHWs and coordinated with clinical care was associated with beneficial improvements in type 2 diabetes control, but both engagement groups showed strong improvements.

A Chronic Care Management Framework Bridging Clinic, Home, and Community Care in a Mexican American Population.

Despite evidence that chronic care management improves outcomes, a framework designed for low income, uninsured populations is still needed to improve health disparities and guide further replication. We describe the Innovative Care for Chronic Conditions framework implemented by a coalition of clinics and agencies to address chronic care management for Mexican Americans with Type 2 diabetes mellitus who have low income and primarily uninsured. The core elements of the framework are described by clinic, home and community settings with community health workers playing an essential role in the delivery of community-based services that address the social determinants of health. Promising results are described. This framework expands the understanding of chronic care management approaches and contributes to further replication of the framework in diverse settings.

A comparison of posttraumatic stress disorder between combat casualties and civilians treated at a military burn center.

BACKGROUND: Posttraumatic stress disorder (PTSD) has been identified in 12% to 20% of noninjured veterans and in 32% of combat casualties. Eight percent of the US general population experience PTSD symptoms, whereas 25.5% of civilians with major burns have PTSD. Known predictors of physical outcomes of patients with burn are age, total body surface area (TBSA) burned, and Injury Severity Score (ISS). The United States Army Institute of Surgical Research Burn Center provides burn care for combat casualties and civilians. We hypothesized that we would find no difference in PTSD incidence between these two populations and that age, TBSA, and ISS are associated with PTSD. METHOD: We retrospectively examined the clinical records of 1,792 patients admitted between October 2003 and May 2008. Records were stratified by PTSD, age, TBSA, and ISS. PTSD scores were compared. Descriptive analyses were used. RESULTS: Four hundred ninety-nine patients (372 military [74.5%]; 127 civilians [25.5%]) were assessed for PTSD using PTSD checklist military and civilian versions. PTSD was defined as >or=44 on the PTSD checklist instruments. We found no significant difference in PTSD between combat casualties and civilians (25% vs. 17.32%, p = 0.761). TBSA and ISS were significantly associated with PTSD; however, no association between age and PTSD was found. CONCLUSION: The incidence of PTSD is not significantly different in burned combat casualties and civilians treated at the same burn unit. These findings suggest that PTSD is related to the burn trauma and not to the circumstances surrounding the injury.
