RESUMO
BACKGROUND AND OBJECTIVES: This study characterizes the multiple morbidities experienced by senior-aged women Veterans so that the Veterans Health Administration (VHA) and other healthcare systems may be better prepared to meet the healthcare needs of this growing cohort. RESEARCH DESIGN AND METHODS: Using the VHA's Corporate Data Warehouse (CDW), we conducted a retrospective observational study of the 38,597 female veteran patients who were at least sixty-five years old and received care in the VHA during 2013 and 2014. We use a latent class analysis model to cluster diagnoses associated with inpatient and outpatient events over the years. RESULTS: The senior-aged women Veterans are characterized by six major classes of disease clusters. We defined these classes as: Healthy (16.24% of the cohort); Ophthalmological Disorders (13.84%); Musculoskeletal Disorders (14.22%); At Risk for Cardiovascular Disease (37.53%); Diabetic with Comorbidities (9.05%); and Multimorbid (9.12%). The patterns and prevalence of these condition classes vary by race, age and marital status. DISCUSSION AND IMPLICATIONS: Each of the six clusters can be used to develop clinical practice guidelines that are appropriate for senior-aged women Veterans. Consistent with past literature, the most common conditions in this cohort are hypertension and hyperlipidemia; together they form the most common class, "At Risk of Cardiovascular Disease (CVD)". Results also show evidence of race-related disparities, with Blacks being more likely to be in the highest risk classes. Also, members of the cohort who are currently married having improved chances of being in the healthy class. And finally, we see a "healthy survivor" effect with the oldest women in our cohort having low overall rates of disease.
RESUMO
The Community Health Worker (CHW) model has been used to combat disparities in healthcare access by utilizing community members as healthcare liaisons to promote improved community health. CHW interventions have been effective in improving diabetes management. This case study reports on a low-intensity CHW intervention in a predominantly Hispanic and non-Hispanic Black population in two Chicago neighborhoods: North Lawndale and South Lawndale. CHWs conducted door-to-door outreach and, for individuals with self-reported type 2 diabetes, offered home visits at baseline and one-year follow-up to provide diabetes education, create an individual management strategy, and refer to clinic-based support services. During 2012, 459 participants were enrolled, with 343 completing follow-up visits in 2013 (75 % retention). The mean HbA1c decrease was 0.5 %. At follow-up, participants were less likely to be depressed, to forget to take their diabetes medications, and were more likely to report higher social support and score higher on an assessment of diabetes knowledge. Patients who were younger, Hispanic, had uncontrolled diabetes, and had lower levels of diabetes self-care at baseline demonstrated increased odds of a significant HbA1c decrease with the intervention than patients without these characteristics. This study demonstrates the effectiveness of a home-based, low-intensity CHW intervention in medically underserved communities, and identifies population groups who might benefit the most from future similar CHW interventions.
