Emergency Department Utilization among Underserved African American Older Adults in South Los Angeles

Pharmacists and transitions of care from emergency department to home

OBJECTIVES

To determine the impact of a pharmacist-led telephone outreach program among patients discharged from the emergency department (ED) to home.

STUDY DESIGN

We conducted a randomized controlled study from February to November 2019 at a tertiary care academic medical center.

METHODS

At ED discharge, participants were randomly assigned to usual care (controls) or usual care plus the pharmacist's review (intervention group). Eligible individuals included those being discharged from the ED to home with 8 or more medications. A pharmacist telephoned patients in the intervention group within 48 to 96 hours after ED discharge. The medications in the patient's record from the ED were compared with what the patient was taking at home. Discrepancies were communicated to the primary provider via fax or telephone. The primary outcome was overall health care utilization including unplanned hospital readmissions or ED visits within 30 days of discharge. The effect of the intervention on the number of acute events was analyzed using a Poisson regression model adjusting for relevant baseline characteristics.

RESULTS

Of 90 eligible participants, 45 patients each were in the intervention and control groups. A total of 26 patients (58%) in the intervention group were reached, and 56 interventions were provided by the pharmacists. There was no significant difference between groups for overall health care utilization (adjusted risk ratio [aRR], 1.01; 95% CI, 0.50-2.06; P = .96), hospitalizations (aRR, 0.20; 95% CI, 0.02-2.18; P = .19), and ED visits (aRR, 1.24; 95% CI, 0.56-2.79; P = .59).

CONCLUSIONS

A pharmacist-led telephone outreach program conducted after ED discharge was not associated with a change in health care utilization.

Disease risk and healthcare utilization among ancestrally diverse groups in the Los Angeles region

An individual's disease risk is affected by the populations that they belong to, due to shared genetics and environmental factors. The study of fine-scale populations in clinical care is important for identifying and reducing health disparities and for developing personalized interventions. To assess patterns of clinical diagnoses and healthcare utilization by fine-scale populations, we leveraged genetic data and electronic medical records from 35,968 patients as part of the UCLA ATLAS Community Health Initiative. We defined clusters of individuals using identity by descent, a form of genetic relatedness that utilizes shared genomic segments arising due to a common ancestor. In total, we identified 376 clusters, including clusters with patients of Afro-Caribbean, Puerto Rican, Lebanese Christian, Iranian Jewish and Gujarati ancestry. Our analysis uncovered 1,218 significant associations between disease diagnoses and clusters and 124 significant associations with specialty visits. We also examined the distribution of pathogenic alleles and found 189 significant alleles at elevated frequency in particular clusters, including many that are not regularly included in population screening efforts. Overall, this work progresses the understanding of health in understudied communities and can provide the foundation for further study into health inequities.

Call to action: equity, diversity, and inclusion in emergency medicine resident physician selection

OBJECTIVES

This call to action seeks to improve emergency care in Canada for equity-deserving communities, enabled by equitable representation among emergency physicians nationally. Specifically, this work describes current resident selection processes and makes recommendations to enhance the equity, diversity, and inclusion (EDI) of resident physician selection in Canadian emergency medicine (EM) residency programs.

METHODS

A diverse panel of EM residency program directors, attending and resident physicians, medical students, and community representatives met monthly from September 2021 to May 2022 via videoconference to coordinate a scoping literature review, two surveys, and structured interviews. This work informed the development of recommendations for incorporating EDI into Canadian EM resident physician selection. At the 2022 Canadian Association of Emergency Physicians (CAEP) Academic Symposium, these recommendations were presented to symposium attendees composed of national EM community leaders, members, and learners. Attendees were divided into small working groups to discuss the recommendations and address three conversation-facilitating questions.

RESULTS

Symposium feedback informed a final set of eight recommendations to promote EDI practices during the resident selection process that address recruitment, retention, mitigating inequities and biases, and education. Each recommendation is accompanied by specific, actionable sub-items to guide programs toward a more equitable selection process. The small working groups also described perceived barriers to the implementation of these recommendations and outlined strategies for success that are incorporated into the recommendations.

CONCLUSION

We call on Canadian EM training programs to implement these eight recommendations to strengthen EDI practices in EM resident physician selection and, in doing so, help to improve the care that patients from equity-deserving groups receive in Canada's emergency departments (EDs).

Emergency Department Utilization, Hospital Admissions, and Office-Based Physician Visits Among Under-Resourced African American and Latino Older Adults

OBJECTIVES

This study uses a theoretical model to explore (a) emergency department (ED) utilization, (b) hospital admissions, and (c) office-based physician visits among sample of under-resourced African American and Latino older adults.

METHODS

Nine hundred five African American and Latino older adults from an under-resourced urban community of South Los Angeles participated in this study. Data was collected using face-to-face interviews. Poisson and logistic regression analysis were used to estimate the parameters specified in the Andersen behavioral model. Predictors included predisposing factors, defined as demographic and other personal characteristics that influence the likelihood of obtaining care, and enabling factors defined as personal, family, and community resources that support or encourage efforts to access health services.

RESULTS

African American older adults have a greater frequency of hospital admissions, ED, and physician visits than their Latino counterparts. About 25%, 45%, and 59% of the variance of the hospital admissions, ED utilization, and physician visits could be explained by predisposing and enabling characteristics. Lower health-related quality of life was associated with a higher number of hospital admissions, ED, and physician visits. Financial strain and difficulty accessing medical care were associated with a higher number of hospital admissions. Being covered by Medicare and particularly Medi-Cal were positively associated with higher hospital admissions, ED, and physician visits.

DISCUSSION

Compared to African American older adults, Latino older adults show higher utilization of (a) emergency department (ED) utilization, (b) hospital admissions, and (c) office-based physician visits. A wide range of predisposing and enabling factors such as insurance and financial difficulties correlate with some but not other types of health care use. Multi-disciplinary, culturally sensitive, clinic- and community-based interventions are needed to address enabling and predisposing factors that influence ED utilization and hospital admission among African American and Latino older adults in under-resourced communities.

Technological Proficiencies, Engagement, and Practical Considerations for mHealth Programs at an Urban Safety-Net Hospital Emergency Departments: Data Analysis

Background

Safety-net emergency departments often serve as the primary entry point for medical care for low income predominantly minority patient populations. Herein, we sought to provide insight into the feasibility, technological proficiencies, engagement characteristics, and practical considerations for a mHealth intervention at a safety-net emergency department.

Objective

We aimed to analyze patient technological proficiency to understand the feasibility of and draw practical considerations for mobile phone technology (mHealth) solutions for patients with chronic disease served by safety-net emergency departments.

Methods

We analyzed data from a previous diabetes randomized clinical mHealth trial for a diabetes social support intervention. Patients from a safety-net emergency department with preexisting diabetes who used SMS text messages, owned a mobile phone, and with hemoglobin A_1c levels >8.5% were enrolled. A text message–based mHealth program to improve disease self-management was provided to all patients. Supporters of patients were randomized to receive a mailed copy or mHealth-based curriculum designed to improve diabetes support. Among enrolled patients, we surveyed mobile technological capacity and frequency of use. We performed latent class analysis to identify classes of patients by level of technological proficiency and compared demographic characteristics between the latent classes to identify demographic subgroups that may require more training or tailoring of the mHealth approach. Study engagement between classes was assessed by comparing the mean number of text messages exchanged, loss to follow-up, and early termination.

Results

Of 1876 patients who were approached, 44.2% (n=829) of patients had a stable mobile phone and were able to use text messages. Among them 166 met the trial inclusion and enrolled, 90% (149/166) of the cohort were ethnically diverse. Significant variance was found in technology capacity and frequency of use. Our latent class analysis classified 75% (124/166) of patients as highly technologically proficient and 25% (42/166) patients as minimally technologically proficient. Age (P<.001) and level of education (P<.001) were associated with class membership. Highly technologically proficient patients were younger and had higher levels of education (45.74 years old; high school or more: 90%) than minimally technologically proficient patients (53.64 years old; high school or more: 18%). Highly technologically proficient participants exchanged a mean of 40 text messages with the system coordinators compared to a mean of 10 text messages by minimally technologically proficient patients (P<.001).

Conclusions

This study found that nearly half of the patients screened at the safety-net emergency department were equipped for an SMS text message–based mHealth intervention. In the small sample of patients who were enrolled, the majority were classified as highly technologically proficient. These highly proficient patients had greater study engagement. mHealth use in emergency departments may be an opportunity to improve health of ethnically diverse populations by pairing sophisticated chronic disease self-management program with SMS text message–based and traditional in-person interventions to reach patients through the method that is most familiar and comfortable.

Evaluating racial disparities in healthcare system utilization and caregiver burden among older adults with dementia

OBJECTIVE

To evaluate racial differences in healthcare utilization and caregiver burden in a culturally diverse population of older adults with dementia.

METHOD

One hundred and thirty-three dyads (person with dementia, PWD and caregiver, CG), with at least one emergency department (ED) visit or hospitalization 12 months prior, were enrolled. Independent sample t-tests and chi-squared analyses were performed to compare racial groups on healthcare utilization and CG burden. Mann-Whitney U test was used for item-level analyses, principal component analysis was used to examine relationships among outcomes, and regressions were used to identify the relationship between race and potential covariates.

RESULTS

PWD sample mean age was 79 years, predominantly female, and with high school education. Racial distribution was 65% White and 35% Black. CG sample mean age was 64 years, predominantly female, with more than 12 years of education. No differences were found for age or dementia severity across racial groups. Black PWD experienced more ED and ambulance utilization when compared to White counterparts. Non-emergency hospitalization rates were higher for White PWD. No significant differences were found by race for CG burden total score; however, item-level analysis suggested more anger, reduced social life, uncertainty, and inadequacy in White CGs. Regressions demonstrated a positive relationship between Black race and adult-child CGs with increased ED visits, while dyad educational attainment was associated with hospitalizations independent of race.

CONCLUSIONS

Healthcare utilization disparities extend to older adults with dementia diagnoses. Our findings suggest that culturally tailored interventions may be appropriate. Future research is encouraged to explore the effect of other covariates.

Psychotropic and Opioid-Based Medication Use among Economically Disadvantaged African-American Older Adults

African-American older adults, particularly those who live in economically deprived areas, are less likely to receive pain and psychotropic medications, compared to Whites. This study explored the link between social, behavioral, and health correlates of pain and psychotropic medication use in a sample of economically disadvantaged African-American older adults. This community-based study recruited 740 African-American older adults who were 55+ yeas-old in economically disadvantaged areas of South Los Angeles. Opioid-based and psychotropic medications were the outcome variables. Gender, age, living arrangement, socioeconomic status (educational attainment and financial strain), continuity of medical care, health management organization membership, sleeping disorder/insomnia, arthritis, back pain, pain severity, self-rated health, depressive symptoms, and major chronic conditions were the explanatory variables. Logistic regression was used for data analyses. Arthritis, back pain, severe pain, and poor self-rated health were associated with opioid-based medications. Pain severity and depressive symptoms were correlated with psychotropic medication. Among African-American older adults, arthritis, back pain, poor self-rated health, and severe pain increase the chance of opioid-based and psychotropic medication. Future research should test factors that can reduce inappropriate and appropriate use and prescription of opioid-based and psychotropic medication among economically disadvantaged African-American older adults.

Smoking Status and Well-Being of Underserved African American Older Adults

Purpose: This study investigated the association between current and past cigarette smoking, with four domains of well-being, namely, physical quality of life, mental quality of life, depressive symptoms, and self-rated health status (SRH), among older African American adults who lived in economically impoverished areas of South Los Angles. Methods: This community-based cross-sectional study included a convenience sample of economically-disadvantaged African Americans adults (n = 740) who were 55 years old and older residing in South Los Angeles. We conducted in-depth face-to-face interviews to collect data on the socioeconomic status (level of education and fiscal pressures), demographic factors (age and gender), physical health (number of chronic medical conditions), smoking (never smokers (reference group), past smokers, and current smokers), and well-being (quality of life, depressive symptoms, and self-rated health). Linear regressions were used to analyze the data. Results: Over 21% reported that they are current smokers, compared with 31% who identified as former smokers. Almost 40% perceived the quality of their health status to be fair or poor. Compared with non-smokers, current cigarette smokers reported a worse physical quality of life, depressive symptoms, and self-rated health. Current smokers also reported a marginally worse mental quality of life. Past smoker status was inconsistently associated with worse well-being in some, but not all, indicators. The association between smoking status and worse well-being was independent of gender, socioeconomic status, and physical health status. Conclusion: Current smoking is associated with worse well-being of older African American adults in economically constrained urban settings. As the same pattern could not be found for former smokers, quitting smoking may be a strategy for economically-disadvantaged African American individuals to enhance their well-being. This provides additional support for programs that help African American individuals who are smokers to quit smoking, particularly in economically-disadvantaged urban areas.

Eye Examination Recency among African American Older Adults with Chronic Medical Conditions

Background: Pervasive racial and economic inequalities have a disproportionate impact on health care utilization among African Americans. One area where we see such disparities is in the recency of eye examinations among the economically disadvantaged. However, our current understanding of the barriers and facilitators of eye examinations in underserved African-American older adults is limited. Aims: Building on Andersen’s model of health service use and using an exploratory approach; we tested various demographic, social, and health factors that were associated with eye examination among underserved middle-aged and older adults in South Los Angeles. We examined predisposing characteristics, enabling factors, and need-for-care characteristics. Methods: With a cross-sectional design, we conducted this survey on a convenience sample of (n = 740) non-institutionalized African-American older adults who were 55+ years old and residing in South Los Angeles, CA, USA. Data were collected on demographic factors, continuity of care, access to care, self-rated health, chronic medical conditions, and depressive symptoms. The outcome was recency of eye examination. Multivariate regression was used for data analysis. Results: 59% of the participants had received at least one eye examination during the last 12 months. A total of 17% had an eye examination within the last two years. Notably, 26% of diabetic participants did not have an eye examination within the last two years. One out of four participants indicated that, within the last two years, no provider ever recommended that they receive an eye examination. Age, education, continuity of medical care, accessibility of medical care, satisfaction with medical care, providers’ recommendation for eye examination, self-rated health, and a diagnosis of hypertension and diabetes mellitus were predictors of eye examination recency. Overall, our analysis indicates that these enabling factors accounted for most of the variance in the recency of eye examinations. Conclusion: A large proportion of underserved African-American middle-aged and older adults in South Los Angeles do not comply with the recommended annual eye examination. This is, in part, because about one-third of them have not received an eye exam recommendation from their health care providers. However, a wide range of factors such as age, education, continuity of care, satisfaction with access, self-rated health, and a diagnosis of hypertension and diabetes mellitus, also influence whether or not African-American middle-aged and older adults receive an eye examination. Programs should address a wide range of multi-level factors to tackle this health inequality.

Polypharmacy Is Associated with Lower Memory Function in African American Older Adults

Although previous research has linked polypharmacy to lower cognitive function in the general population, we know little about this association among economically challenged African American (AA) older adults. This study explored the link between polypharmacy and memory function among AA older adults. This community-based study recruited 399 AA older adults who were 65+ years old and living in economically disadvantaged areas of South Los Angeles. Polypharmacy (taking 5+ medications) was the independent variable, memory function was the outcome variable (continuous variable), and gender, age, living arrangement, socioeconomic status (educational attainment and financial strain), health behaviors (current smoking and any binge drinking), and multimorbidity (number of chronic diseases) were the covariates. Linear regression was used for data analyses. Polypharmacy was associated with lower scores on memory function, above and beyond covariates. Among AA older adults, polypharmacy may be linked to worse cognitive function. Future research should test the mechanisms by which polypharmacy is associated with lower levels of cognitive decline. There is a need for screening for memory problems in AA older adults who are exposed to polypharmacy.

Insomnia Symptoms among African-American Older Adults in Economically Disadvantaged Areas of South Los Angeles

BACKGROUND

Although psychosocial and health factors impact insomnia symptoms, less is known about these effects in economically disadvantaged African-American older adults.

AIMS

This study investigated social and health determinants of insomnia symptoms among economically disadvantaged African-American older adults.

METHODS

This survey enrolled 398 African-American older adults (age ≥ 65 years) from economically disadvantaged areas of South Los Angeles. Gender, age, educational attainment, financial difficulty, number of chronic diseases, self-rated health, pain intensity, and depression were covariates. Total insomnia, insomnia symptoms, and insomnia impact were our outcomes. Linear regression was applied for data analysis.

RESULTS

Based on linear regression, higher financial difficulty (B = 0.48, 95% CI = 0.35-0.61), smoking status (B = 1.64, 95% CI = 0.13-3.16), higher pain intensity (B = 0.39, 95% CI = 0.11-0.67), higher number of chronic diseases (B = 0.34, 95% CI = 0.05-0.64), and more depressive symptoms (B = 0.35, 95% CI = 0.12-0.57) were associated with a higher frequency of insomnia symptoms. Based on a logistic regression model, lower age (B = 0.91, 95% CI = 0.91-1.00) and high financial difficulty (OR = 1.15, 95% CI = 1.08-1.24), pain (OR = 2.08, 95% CI = 1.14-3.80), chronic disease (OR = 1.27, 95% CI = 1.07-1.51) and depression (OR = 2.38, 95% CI = 1.22-4.65) were associated with higher odds of possible clinical insomnia. We also found specific predictors for insomnia symptoms and insomnia impact.

CONCLUSIONS

Among African-American older adults in economically disadvantaged areas of South Los Angeles, insomnia symptoms co-occur with other economic, physical, and mental health challenges such as financial difficulty, smoking, multimorbidity, pain, and depression. There is a need to address sleep as a component of care of economically disadvantaged African-American older adults who have multiple social and health challenges.

Obesity and Polypharmacy among African American Older Adults: Gender as the Moderator and Multimorbidity as the Mediator

Despite high prevalence of obesity and polypharmacy among African American (AA) older adults, little information exists on the associations between the two in this population. This study explored the association between obesity and polypharmacy among AA older adults who were residing in poor urban areas of South Los Angeles. We also investigated role of gender as the moderator and multimorbidity as the mediator of this association. In a community-based study in South Los Angeles, 308 AA older adults (age ≥ 55 years) were entered into this study. From this number, 112 (36.4%) were AA men and 196 (63.6%) were AA women. Polypharmacy (taking 5+ medications) was the dependent variable, obesity was the independent variable, gender was the moderator, and multimorbidity (number of chronic medical conditions) was the mediator. Age, educational attainment, financial difficulty (difficulty paying bills, etc.), income, marital status, self-rated health (SRH), and depression were the covariates. Logistic regressions were used for data analyses. In the absence of multimorbidity in the model, obesity was associated with higher odds of polypharmacy in the pooled sample. This association was not significant when we controlled for multimorbidity, suggesting that multimorbidity mediates the obesity-polypharmacy link. We found significant association between obesity and polypharmacy in AA women not AA men, suggesting that gender moderates such association. AA older women with obesity are at a higher risk of polypharmacy, an association which is mainly due to multimorbidity. There is a need for screening for inappropriate polypharmacy in AA older women with obesity and associated multimorbidity.

Depression Fully Mediates the Effect of Multimorbidity on Self-Rated Health for Economically Disadvantaged African American Men but Not Women

Background. Although chronic medical conditions (CMCs), depression, and self-rated health (SRH) are associated, their associations may depend on race, ethnicity, gender, and their intersections. In predominantly White samples, SRH is shown to better reflect the risk of mortality and multimorbidity for men than it is for women, which suggests that poor SRH among women may be caused not only by CMCs, but also by conditions like depression and social relations-a phenomenon known as "the sponge hypothesis." However, little is known about gender differences in the links between multimorbidity, depression, and SRH among African Americans (AAs). Objective. To study whether depression differently mediates the association between multimorbidity and SRH for economically disadvantaged AA men and women. Methods. This survey was conducted in South Los Angeles between 2015 to 2018. A total number of 740 AA older adults (age ≥ 55 years) were enrolled in this study, of which 266 were AA men and 474 were AA women. The independent variable was the number of CMCs. The dependent variable was SRH. Age and socioeconomic status (educational attainment and marital status) were covariates. Depression was the mediator. Gender was the moderator. Structural Equation Modeling (SEM) was used to analyze the data. Results. In the pooled sample that included both genders, depression partially mediated the effect of multimorbidity on SRH. In gender specific models, depression fully mediated the effects of multimorbidity on SRH for AA men but not AA women. For AA women but not AA men, social isolation was associated with depression. Conclusion. Gender differences exist in the role of depression as an underlying mechanism behind the effect of multimorbidity on the SRH of economically disadvantaged AA older adults. For AA men, depression may be the reason people with multimorbidity report worse SRH. For AA women, depression is only one of the many reasons individuals with multiple CMCs report poor SRH. Prevention of depression may differently influence the SRH of low-income AA men and women with multimorbidity.

Associations between Polypharmacy, Self-Rated Health, and Depression in African American Older Adults; Mediators and Moderators

Background. Despite the prevalence of multimorbidity among African American (AA) older adults, little information exists on correlates of polypharmacy (using 5+ medications) in AA older adults. There is more information available regarding the link between polypharmacy and physical aspects of health than subjective ones. Aims. In a local sample of AA older adults in Los Angeles, this study investigated the association of polypharmacy with self-rated health (SRH) and depression. We also explored gender differences in these links. Methods. This community-based study was conducted in south Los Angeles. A total number of 708 AA older adults (age ≥ 55 years) were entered into this study. From this number, 253 were AA men and 455 were AA women. Polypharmacy was the independent variable. Self-rated health (SRH) and depression were the dependent variables. Age, educational attainment, financial difficulty (difficulty paying bills, etc.), and marital status were covariates. Gender was the moderator. Multimorbidity, measured as the number of chronic diseases (CDs), was the mediator. Logistic regressions were applied for data analysis. Results. Polypharmacy was associated with worse SRH and depression. Multimorbidity fully mediated the association between polypharmacy and depressive symptoms. Multimorbidity only partially mediated the association between polypharmacy and poor SRH. Gender moderated the association between polypharmacy and SRH, as polypharmacy was associated with poor SRH in women but not men. Gender did not alter the association between polypharmacy and depression. Conclusions. AA older women with polypharmacy experience worse SRH and depression, an association which is partially due to the underlying multimorbidity. There is a need for preventing inappropriate polypharmacy in AA older adults, particularly when addressing poor SRH and depression in AA older women with multimorbidity.
