Bias reported by family caregivers in support received when assisting patients with cancer-related decision-making
(Wiley, 2022) Dionne-Odom, J. Nicholas; Ornstein, Katherine A.; Azuero, Andres; Harrell, Erin R.; Gazaway, Shena; Watts, Kristen Allen; Ejem, Deborah; Bechthold, Avery C.; Lee, Kyungmi; Puga, Frank; Miller-Sonet, Ellen; Williams, Grant R.; Kent, Erin E.; University of Alabama Birmingham; Icahn School of Medicine at Mount Sinai; University of Alabama Tuscaloosa; University of North Carolina; University of North Carolina Chapel Hill
Background: Family caregivers play an increasing role in cancer treatment decision-making. We examined bias reported by family caregivers in the support they and their patient received from their healthcare team when making these decisions, including associations with distress. Methods: Analysis of 2021 national survey data of family caregivers of patients with cancer (N = 2703). Bias experienced in decision support was assessed with the item: "Have you felt that the support you and the person with cancer have received for making cancer-related decisions by your doctor or healthcare team has been negatively affected by any of the following?" Check-all-that-apply response options included: age, race, language, education, political affiliation, body weight, insurance type or lack of insurance, income, religion, sexual orientation, and gender/sex. Chi-square and regression analyses assessed associations between bias and caregiver distress (GAD-2, PHQ-2). Results: Of 2703 caregiver respondents, 47.4% (n = 1281) reported experiencing ≥1 bias(es) when receiving decision support for making cancer-related decisions. Bias was more prevalent among younger caregivers, males, transwomen/men or gender non-conforming caregivers, racial/ethnic minorities, and those providing care over a longer time period. The odds of having high anxiety (GAD-2 scores ≥ 3) were 2.1 times higher for caregivers experiencing one type of bias (adjusted OR, 2.1; 95% CI, 1.6-2.8) and 4.2 times higher for caregivers experiencing ≥2 biases (adjusted OR, 4.2; 95% CI, 3.4-5.3) compared to none. Similar results were found for high depression scores (PHQ-2 scores ≥ 3). Conclusions: Nearly half of caregivers involved in their care recipients' cancer-related decisions report bias in decision support received from the healthcare team. Experiencing bias was strongly associated with high psychological distress.
Diagnostic Yield of Population-Based Screening for Chronic Kidney Disease in Low-Income, Middle-Income, and High-Income Countries
(American Medical Association, 2021) Tonelli, Marcello; Tiv, Sophanny; Anand, Shuchi; Mohan, Deepa; Garcia, Guillermo Garcia; Padilla, Jose Alfonso Gutierrez; Klarenbach, Scott; Blackaller, Guillermo Navarro; Seck, Sidy; Wang, Jinwei; Zhang, Luxia; Muntner, Paul; University of Calgary; University of Alberta; Stanford University; Madras Diabetes Research Foundation; Universidad de Guadalajara; Peking University; University of Alabama Tuscaloosa
This epidemiologic assessment of population-based cohorts investigates the change in treatment for chronic kidney disease associated with population-based screening compared with measuring blood pressure and assessing glycemia. Question How frequently is population-based screening for chronic kidney disease (CKD) associated with a change in recommended treatment compared with a strategy of measuring blood pressure and assessing glycemia? Findings This epidemiologic assessment of 126 242 adults screened for CKD in population-based cohorts from China, India, Mexico, Senegal, and the United States found that most treatment gaps identified by population-based screening for CKD were apparent by measuring blood pressure or glycemic control. Case finding, defined by testing for CKD only in adults with hypertension or diabetes, was associated with a lower frequency of testing and a greater proportion of individuals with identified treatment gaps compared with screening. Meaning These findings suggest that case finding was more efficient than population-based screening and detected most patients with CKD requiring treatment changes. Importance Population-based screening for chronic kidney disease (CKD) is sometimes recommended based on the assumption that detecting CKD is associated with beneficial changes in treatment. However, the treatment of CKD is often similar to the treatment of hypertension or diabetes, which commonly coexist with CKD. Objective To determine the frequency with which population-based screening for CKD is associated with a change in recommended treatment compared with a strategy of measuring blood pressure and assessing glycemia. Design, Setting, and Participants This cohort study was conducted using data obtained from studies that evaluated CKD in population-based samples from China (2007-2010), India (2010-2014), Mexico (2007-2008), Senegal (2012), and the United States (2009-2014), including a total of 126 242 adults screened for CKD. Data were analyzed from January 2020 to March 2021. Main Outcomes and Measures The primary definition of CKD was estimated glomerular filtration rate less than 60 mL/min/1.73 m(2). For individuals with CKD, the need for a treatment change was defined as not taking an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker or having blood pressure levels of 140/90 mm Hg or greater. For individuals with CKD who also had diabetes, the need for a treatment change was also defined as having hemoglobin A(1c) levels of 8% or greater or fasting glucose levels of 178.4 mg/dL (9.9 mmol/L) or greater. Case finding was defined as testing for CKD only in adults with hypertension or diabetes. Results Among 126 242 adults screened for CKD, there were 47 204 patients in the China cohort, 9817 patients in the India cohort, 51 137 patients in the Mexico cohort, 2441 patients in the Senegal cohort, and 15 643 patients in the US cohort. The mean age of participants was 49.6 years (95% CI, 49.5-49.7 years) in the China cohort, 42.9 years (95% CI, 42.6-43.2 years) in the India cohort, 51.6 years (95% CI, 51.5-51.7 years) in the Mexico cohort, 48.2 years (95% CI, 47.5-48.9 years) in the Senegal cohort, and 47.3 years (95% CI, 46.6-48.0 years) in the US cohort. The proportion of women was 57.3% (95% CI, 56.9%-57.7%) in the China cohort, 53.4% (95% CI, 52.4%-54.4%) in the India cohort, 68.8% (95% CI, 68.4%-69.2%) in the Mexico cohort, 56.0% (95% CI, 54.0%-58.0%) in the Senegal cohort, and 51.9% (51.0%-52.7%) in the US cohort. The prevalence of CKD was 2.5% (95% CI, 2.4%-2.7%) in the China cohort, 2.3% (95% CI, 2.0%-2.6%) in the India cohort, 10.6% (95% CI, 10.3%-10.9%) in the Mexico cohort, 13.1% (95% CI, 11.7%-14.4%) in the Senegal cohort, and 6.8% (95% CI, 6.2%-7.5%) in the US cohort. Screening for CKD was associated with the identification of additional adults whose treatment would change (beyond those identified by measuring blood pressure and glycemia) per 1000 adults: China: 8 adults (95% CI, 8-9 adults); India: 5 adults (95% CI, 4-7 adults); Mexico: 26 adults (95% CI, 24-27 adults); Senegal: 59 adults (95% CI, 50-69 adults); and the US: 19 adults (95% CI, 16-23 adults). Case finding was associated with the identification of 46.2% (95% CI, 45.1%-47.4%) to 86.4% (95% CI, 85.4%-87.3%) of individuals with CKD depending on the country, an increase in the proportion of individuals requiring a treatment change by as much 89.6% (95% CI, 80.4%-99.3%) in the US, and a decrease in the proportion of individuals needing GFR measurements by as much as 57.8% (95% CI, 56.3%-59.3%) in the US. Conclusions and Relevance This study found that most additional individuals with CKD identified by population-based screening programs did not need a change in treatment compared with a strategy of measuring blood pressure and assessing glycemia and that case finding was more efficient than screening for early detection of CKD.
Does health literacy affect the uptake of annual physical check-ups?: Results from the 2017 US health information national trends survey
(BMC, 2021) Lee, Hee Yun; Kim, Sooyoung; Neese, Jessica; Lee, Mi Hwa; University of Alabama Tuscaloosa; Catholic University Pusan; University of North Carolina; East Carolina University
Background Little is known about how health literacy is linked to physical check-ups. This study aimed to examine the levels of physical check-ups (self-reported check-ups within the last year) by age group (those aged 18-59 years and those aged = >= 60 years) and the role of health literacy regarding physical check-ups in the United States. Methods Data for the study were obtained from the 2017 Health Information National Trends Survey. The original sample included 3,285 respondents, but only 3,146 surveys were used for this study. Andersen's Behavioral Model of Health Services Use guided this study, and a binomial logistic regression model was conducted using Stata 12.0 software package. Results While 82.0 % of the older group had an annual check-up, 67.3 % of the younger group had one. Both groups had similar ratios for health literacy-related item reporting. Study results show that annual check-up was positively associated with confidence in getting health information, having health insurance, and having a primary doctor for both age groups. However, getting a regular check-up was negatively associated with frustration while searching for information among the younger group. In comparison, it was positively associated with difficulty understanding information for the older group. Conclusions To increase annual physical check-ups, health literacy-related interventions should be developed and address the barriers most associated with health check-ups. One way of addressing this barrier is to improve communication from healthcare professionals to consumers through the use of easy-to-understand explanations appropriate for the consumer.
Enrolling a rural community pharmacy as a Vaccines for Children provider to increase HPV vaccination: a feasibility study
(BMC, 2021) Daniel, Casey L.; Lawson, Frances; Vickers, Macy; Green, Chelsea; Wright, Anna; Coyne-Beasley, Tamera; Lee, Hee Y.; Turberville, Stacie; University of South Alabama; University of Alabama Birmingham; University of Alabama Tuscaloosa
Background Human papillomavirus (HPV) is the most common sexually transmitted infection in the U.S. with over 80 million infected individuals. High-risk strains are associated with 6 different cancers. Although infection is preventable, U.S. vaccination rates remain suboptimal and there are noted disparities between urban and rural communities due to economic barriers, lack of access, and low awareness and education. Methods The current pilot study sought to overcome these barriers through an interprofessional collaborative enrolling a community pharmacy in a rural, medically underserved Alabama county as a Vaccines for Children (VFC) provider to provide free vaccines to eligible adolescents. Program evaluation was conducted to determine the intervention's feasibility. Potential efficacy was assessed by analyzing county-level HPV vaccination uptake and completion rates using state immunization registry data. Results Over the 8-month study, 166 total vaccines were administered to 89 adolescents ages 10-18, including 55 doses of HPV vaccine, 53 doses of Tdap vaccine, 45 doses of meningococcal vaccine, and 13 doses of influenza vaccine. Among these adolescents, mean age was 12.6 years old, and 64 (71.9%) were VFC patients. The pharmacy recorded an increase in total vaccine administration of 158.8%, an increase in prescription revenue of 34.8%, and an increase in total revenue by 24.4% during the course of the study, compared to the previous year. Conclusions Findings from the current work demonstrate the potential of this strategy and can serve as a blueprint for statewide and national dissemination and implementation to ultimately increase access to vaccination services, increase vaccination rates, and reduce urban-rural vaccine disparities.
The HIV treatment cascade and care continuum: updates, goals, and recommendations for the future
(BMC, 2016) Kay, Emma Sophia; Batey, D. Scott; Mugavero, Michael J.; University of Alabama Tuscaloosa; University of Alabama Birmingham
The HIV care continuum is a framework that models the dynamic stages of HIV care. The continuum consists of five main steps, which, at the population level, are depicted cross-sectionally as the HIV treatment cascade. These steps include diagnosis, linkage to care (LTC), retention in care (RiC), adherence to antiretroviral therapy (ART), and viral suppression. Although the HIV treatment cascade is represented as a linear, unidirectional framework, persons living with HIV (PLWH) often experience the care continuum in a less streamlined fashion, skip steps altogether, or even exit the continuum for a period of time and regress to an earlier stage. The proportion of PLWH decreases at each successive step of the cascade, beginning with an estimated 86% who are diagnosed and dropping dramatically to approximately 30% of PLWH who are virally suppressed in the United States (US). In this current issues review, we describe each step in the cascade, discuss targeted interventions that address weak points in the continuum, review domestic and international policies that help shape and direct HIV care strategies, and conclude with recommendations and future directions for HIV providers and policymakers. While we primarily examine issues related to domestic HIV care in the US, we also discuss international applications of the continuum in order to provide broader context.
Human-Technology Interaction Factors Associated With the Use of Electronic Personal Health Records Among Younger and Older Adults: Secondary Data Analysis
(JMIR Publications, 2021) Luo, Yan; Dozier, Krystal; Ikenberg, Carin; University of Alabama Tuscaloosa
Background: An electronic personal health record (ePHR), also known as a personal health record (PHR), has been broadly defined as an electronic application through which individuals can access, manage, and share their health information in a secure and confidential environment. Although ePHRs can benefit individuals as well as caregivers and health care providers, the use of ePHRs among individuals continues to remain low. Objective: The current study aims to examine the relationship between human-technology interaction factors and ePHR use among adults and then to compare the different effects of human-technology interaction factors on ePHR use between younger adults (18-54 years old) and older adults (55 years of age and over). Methods: We analyzed data from the Health Information National Trends Survey (HINTS 5 cycle 3) collected from US adults aged 18 years old and over in 2019. Descriptive analysis was conducted for all variables and each item of ePHR use. Bivariate tests (Pearson correlation coefficient for categorical variable and F test for continuous variables) were conducted over 2 age groups. Finally, after adjustments were made for sociodemographics and health care resources, a weighted multiple linear regression was conducted to examine the relationship between human-technology interaction factors and ePHR use. Results: The final sample size of 1363 (average age 51.19) was divided into 2 age groups: 18 to 54 years old and 55 years old and older. The average level of ePHR use was low (mean 2.76, range 0-8). There was no significant difference in average ePHR use between the 2 age groups. Including clinical notes was positively related to ePHR use in both groups: 18 to 54 years old (beta=.28, P=.005), 55 years old and older (beta=.15, P=.006). Although accessing ePHRs using a smartphone app was only associated with ePHR use among younger adults (beta=.29; P<.001), ease of understanding health information in ePHRs was positively linked to ePHR use only among older adults (beta=.13; P=.003). Conclusions: This study found that including clinical notes was positively related to ePHR use in both age groups, which suggested that including clinical notes as a part of ePHRs might improve the effective use of ePHRs among patients. Moreover, accessing ePHRs using a smartphone app was associated with higher ePHR use among younger adults while ease of understanding health information in ePHRs was linked to higher ePHR use among older adults. The design of ePHRs should provide the option of being accessible through mobile devices to promote greater ePHR use among young people. For older adults, providers could add additional notes to explain the health information recorded in the ePHRs.
Limited English Proficiency and Trajectories of Depressive Symptoms Among Mexican American Older Adults
(Oxford University Press, 2019) Kim, Giyeon; Kim, Minjung; Park, Soohyun; Jimenez, Daniel E.; Chiriboga, David A.; Chung Ang University; Ohio State University; University of Alabama Tuscaloosa; University of Miami; University of South Florida
Background and Objectives: This study examined the effect of limited English proficiency (LEP) on trajectories of depressive symptoms among Mexican American older adults in the United States. Research Design and Methods: The sample was drawn from Waves 1 to 6 (1993-2007) of the Hispanic Established Population for Epidemiological Studies of the Elderly (H-EPESE). A total of 2,945 Mexican American older adults were included in the analyses. A latent growth curve modeling was conducted. Results: After adjusting for covariates, results show that Mexican American older adults with LEP had higher levels of depressive symptoms than those with English proficiency (EP) at baseline as well as over a 14-year period. Differential trajectories were observed between those with LEP and EP over time, indicating that those with LEP had a significantly steeper curve of depressive symptom trajectories over time than those with EP. Discussion and Implications: These results suggest that LEP is a risk factor not merely for greater depressive symptomatology at each time point, but for an accelerated trajectory of depressive symptoms over time among Mexican American older adults. Overall, the findings emphasize the need to assist not only the informal support system of Mexican American older adults with LEP, but also the formal system.
Patterns and Influencing Factors of eHealth Tools Adoption Among Medicaid and Non-Medicaid Populations From the Health Information National Trends Survey (HINTS) 2017-2019: Questionnaire Study
(JMIR Publications, 2021) Yang, Xin; Yang, Ning; Lewis, Dwight; Parton, Jason; Hudnall, Matthew; University of Alabama Tuscaloosa
Background: Evidence suggests that eHealth tools adoption is associated with better health outcomes among various populations. The patterns and factors influencing eHealth adoption among the US Medicaid population remain obscure. Objective: The objective of this study is to explore patterns of eHealth tools adoption among the Medicaid population and examine factors associated with eHealth adoption. Methods: Data from the Health Information National Trends Survey from 2017 to 2019 were used to estimate the patterns of eHealth tools adoption among Medicaid and non-Medicaid populations. The effects of Medicaid insurance status and other influencing factors were assessed with logistic regression models. Results: Compared with the non-Medicaid population, the Medicaid beneficiaries had significantly lower eHealth tools adoption rates for health information management (11.2% to 17.5% less) and mobile health for self-regulation (0.8% to 9.7% less). Conversely, the Medicaid population had significantly higher adoption rates for using social media for health information than their counterpart (8% higher in 2018, P=.01; 10.1% higher in 2019, P=.01). Internet access diversity, education, and cardiovascular diseases were positively associated with health information management and mobile health for self-regulation among the Medicaid population. Internet access diversity is the only factor significantly associated with social media adoption for acquisition of health information (OR 1.98, 95% CI 1.26-3.11). Conclusions: Our results suggest digital disparities in eHealth tools adoption between the Medicaid and non-Medicaid populations. Future research should investigate behavioral correlates and develop interventions to improve eHealth adoption and use among underserved communities.
Regional Variation of Racial Disparities in Mental Health Service Use Among Older Adults
(Oxford University Press, 2013) Kim, Giyeon; Parton, Jason M.; DeCoster, Jamie; Bryant, Ami N.; Ford, Katy L.; Parmelee, Patricia A.; University of Alabama Tuscaloosa; University of Virginia
Purpose: Given the paucity of research on the role of geography in mental health care, this study examined whether racial differences in mental health service use varied across geographic regions among older adults. Design and Methods: Drawn from the Collaborative Psychiatric Epidemiology Surveys (CPES), blacks (n = 1,008) and whites (n = 1,870) aged 60 and older were selected for analysis. Logistic regression analyses were conducted. Results: Results showed significant racial disparities in mental health service use in the overall sample, as well as significant variation by region. Although no racial differences were observed in the Northeast, West, or Midwest regions, black elders in the South were significantly less likely than whites to use mental health services (odds ratios [OR], 2.08; 95% confidence interval [CI], 1.34-3.23). Implications: The findings suggest that improving the access to mental health care in certain regions, the South in particular, may be essential to reduce racial disparities at the national level. Policy implications are discussed.
