Correlates of recency of eye examination among elderly African-Americans

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.

Eye Care Quality and Accessibility Improvement in the Community (EQUALITY): impact of an eye health education program on patient knowledge about glaucoma and attitudes about eye care

Purpose

To assess the impact of the education program of the Eye Care Quality and Accessibility Improvement in the Community (EQUALITY) telemedicine program on at-risk patients’ knowledge about glaucoma and attitudes about eye care as well as to assess patient satisfaction with EQUALITY.

Patients and methods

New or existing patients presenting for a comprehensive eye exam (CEE) at one of two retail-based primary eye clinics were enrolled based on ≥1 of the following at-risk criteria for glaucoma: African Americans ≥40 years of age, Whites ≥50 years of age, diabetes, family history of glaucoma, and/or preexisting diagnosis of glaucoma. A total of 651 patients were enrolled. A questionnaire was administered prior to the patients’ CEE and prior to the patients receiving any of the evidence-based eye health education program; a follow-up questionnaire was administered 2–4 weeks later by phone. Baseline and follow-up patient responses regarding knowledge about glaucoma and attitudes about eye care were compared using McNemar’s test. Logistic regression models were used to assess the association of patient-level characteristics with improvement in knowledge and attitudes. Overall patient satisfaction was summarized.

Results

At follow-up, all patient responses in the knowledge and attitude domains significantly improved from baseline (P≤0.01 for all questions). Those who were unemployed (odds ratio =0.63, 95% confidence interval =0.42–0.95, P=0.026) or had lower education (odds ratio =0.55, 95% confidence interval =0.29–1.02, P=0.058) were less likely to improve their knowledge after adjusting for age, sex, race, and prior glaucoma diagnosis. This association was attenuated after further adjustment for other patient-level characteristics. Ninety-eight percent (n=501) of patients reported being likely to have a CEE within the next 2 years, whereas 63% (n=326) had a CEE in the previous 2 years. Patient satisfaction with EQUALITY was high (99%).

Conclusion

Improved knowledge about glaucoma and a high intent to pursue eye care may lead to improved detection of early disease, thus lowering the risk of blindness.

Inappropriate Medication Use Among Underserved Elderly African Americans

OBJECTIVE

The goal of this study is to identify correlates and the prevalence of potentially inappropriate medication (PIM) use among underserved elderly African Americans.

METHOD

This cross-sectional study recruited 400 elderly African Americans living in South Los Angeles, and used structured, face-to-face surveys. These elicited data pertaining to the type, frequency, dosage, and indications of all medications used by participants.

RESULTS

Seventy percent of participants engaged in PIM use and used at least one medication that was classified as "Avoid" (27%) and "Use Conditionally" (43%) through Beers Criteria. Significant correlations emerged between PIM use and the number of autonomic and central nervous system, neurological and psychotherapeutic medications, medication duplications, and drug-drug interactions.

DISCUSSION

Our findings point to the need for multidisciplinary team programs of health care providers that include primary and specialist physicians, pharmacists, nurses, and social workers. Together, they can improve health outcomes, enhance the quality of life, and reduce morbidity and mortality due to inappropriate medication use.

Eye Care Quality and Accessibility Improvement in the Community (EQUALITY) for adults at risk for glaucoma: study rationale and design

Background

Primary open angle glaucoma is a chronic, progressive eye disease that is the leading cause of blindness among African Americans. Glaucoma progresses more rapidly and appears about 10 years earlier in African Americans as compared to whites. African Americans are also less likely to receive comprehensive eye care when glaucoma could be detected before irreversible blindness. Screening and follow-up protocols for managing glaucoma recommended by eye-care professional organizations are often not followed by primary eye-care providers, both ophthalmologists and optometrists. There is a pressing need to improve both the accessibility and quality of glaucoma care for African Americans. Telemedicine may be an effective solution for improving management and diagnosis of glaucoma because it depends on ocular imaging and tests that can be electronically transmitted to remote reading centers where tertiary care specialists can examine the results. We describe the Eye Care Quality and Accessibility Improvement in the Community project (EQUALITY), set to evaluate a teleglaucoma program deployed in retail-based primary eye care practices serving communities with a large percentage of African Americans.

Methods/Design

We conducted an observational, 1-year prospective study based in two Walmart Vision Centers in Alabama staffed by primary care optometrists. EQUALITY focuses on new or existing adult patients who are at-risk for glaucoma or already diagnosed with glaucoma. Patients receive dilated comprehensive examinations and diagnostic testing for glaucoma, followed by the optometrist’s diagnosis and a preliminary management plan. Results are transmitted to a glaucoma reading center where ophthalmologists who completed fellowship training in glaucoma review results and provide feedback to the optometrist, who manages the care of the patient. Patients also receive eye health education about glaucoma and comprehensive eye care. Research questions include diagnostic and management agreement between providers, the impact of eye health education on patients’ knowledge and adherence to follow-up and medication, patient satisfaction, program cost-effectiveness, and EQUALITY’s impact on Walmart pharmacy prescription rates.

Discussion

As eye-care delivery systems in the US strive to improve quality while reducing costs, telemedicine programs including teleglaucoma initiatives such as EQUALITY could contribute toward reaching this goal, particularly among underserved populations at-risk for chronic blinding diseases.

Pain in Community-Dwelling Elderly African Americans

OBJECTIVE

This study examines the type, severity, and correlates of pain among underserved elderly African Americans.

METHOD

This cross-sectional study includes 400 non-institutionalized underserved aged African Americans, recruited from 16 African American churches located in South Los Angeles.

RESULTS

Two thirds of our participants reported a level of pain of 5 or higher (on a scale of 0-10) for at least one of the pain items. Participants with severe level of pain showed a higher level of insomnia, depression, and deficiency in activity of daily living as well as a lower level of memory function and quality of physical and mental health. Also, level of pain is a statistically significant correlate of office-based physician visits and emergency department admission.

CONCLUSION

Our findings encourage multidisciplinary and interdisciplinary interventions to include pharmacotherapy, psychological support, and physical rehabilitation, specifically on neuropathic pain among aged African Americans with multiple chronic conditions.

A survey of Alabama eye care providers in 2010-2011

BACKGROUND

State level information regarding eye care resources can provide policy makers with valuable information about availability of eye care services. The current study surveyed ophthalmologists, optometrists and vision rehabilitation providers practicing in Alabama.

METHODS

Three mutually exclusive provider groups were identified, i.e., all ophthalmologists, optometrists, and vision rehabilitation providers working in Alabama in 2010. Eligible providers were contacted in 2010 and 2011 and information was requested regarding provider demographics and training, practice type and service characteristics, and patient characteristics. Descriptive statistics (e.g., means, proportions) were used to characterize provider groups by their demographic and training characteristics, practice characteristics, services provided and patients or clients served. In addition, county level figures demonstrate the numbers and per capita ophthalmologists and optometrists.

RESULTS

Ophthalmologists were located in 24 of Alabama's 67 counties, optometrists in 56, and 10 counties had neither an ophthalmologist nor an optometrist. Overall, 1,033 vision care professionals were identified as eligible to participate in the survey: 217 ophthalmologists, 638 optometrists, and 178 visual rehabilitation providers. Of those, 111 (51.2%) ophthalmologists, 246 (38.6%) optometrists, and 81 (45.5%) rehabilitation providers participated. Most participating ophthalmologists, optometrists, and vision rehabilitation providers identified themselves as non-Hispanic White. Ophthalmologists and optometrists estimated that 27% and 22%, respectively, of their patients had diabetes but that the proportion that adhered to eye care guidelines was 61% among ophthalmology patients and 53% among optometry patients.

CONCLUSIONS

A large number of Alabama communities are isolated from eye care services. Increased future demand for eye care is anticipated nationally given the aging of the population and decreasing numbers of providers; however, Alabama also has a high and growing prevalence of diabetes which will result in greater numbers at risk for diabetic retinopathy, glaucoma, and cataracts.

Effect of an eye health education program on older African Americans' eye care utilization and attitudes about eye care

We examined the impact of an eye health education program for older African Americans on attitudes about eye care and utilization, using a randomized trial design in a community setting. Participants were older African Americans attending activities at senior centers: Ten centers were randomized to an eye health education (InCHARGE) or social-contact control presentation. InCHARGE addressed the importance of annual dilated comprehensive examination and strategies reducing barriers to care. The control presentation was on the importance of physical activity. Outcomes were attitudes about eye care 6 months post event through questionnaire and eye care utilization during 12 months post event through medical record abstraction. At baseline, more than 80% participants in both arms said transportation and finding, communicating, and trusting a doctor were not problematic and agreed that yearly care was important. One-fourth said eye examination cost was problematic; one-half said spectacle cost was problematic. There were no group differences 6 months post event. During the 12 months pre event, the dilated exam rate was similar in the groups (38.3% InCHARGE, 40.8% control) and unchanged during the 12 moiths post event. Results suggest fewer than half of older African Americans received annual dilated eye care. Group-administered eye health education did not increase this rate. Even before the program, they had positive attitudes about care, yet many cited examination and spectacle cost as problematic, which was not mitigated by health education. Evidence-based strategies in a community setting for increasing eye care utilization rate in older African Americans have yet to be identified. Policy changes may be more appropriate avenues for addressing cost.

Educating older African Americans about the preventive importance of routine comprehensive eye care

Older African Americans have higher rates of vision impairment and lower utilization rates of comprehensive eye care, compared to Caucasians. InCHARGE is an eye health education program for this population that promotes prevention through the annual, dilated comprehensive eye examination. This study, using a pre-/postdesign, evaluated whether InCHARGE imparted knowledge about prevention and strategies for reducing barriers to care. The program was presented to 85 older African Americans in 5 senior centers in Montgomery, AL. Changes in attitudes about annual eye care were assessed by a questionnaire before and 3 months after InCHARGE. At baseline, most (> 85%) responded it would not be difficult for them to find an ophthalmologist or optometrist, and the exam cost was not a problem. Twenty-five percent reported problems finding transportation to the doctor and covering the eyeglasses cost. Forty-four percent reported not having an eye exam in the past year; 13% reported not having one within 2 years. Three months after InCHARGE, those who reported that they could find a way to get to the doctor increased (X2 = 3.8, p = 0.04). After InCHARGE, 72% said they either had received or scheduled an eye exam. Responses to a question about what was learned from InCHARGE indicated that the InCHARGE's key messages about comprehensive eye care were successfully imparted to most. This study suggests that older African Americans in the urban south have positive attitudes about eye care, even before an eye health education presentation. Following InCHARGE, they identified transportation problems less frequently as a barrier, indicated that they learned InCHARGE's key message and had plans for seeking routine, preventive eye care. A next step is to verify through medical record review the extent to which the high rates of self-reported eye care utilization reflect behavior.

Correlates of complementary and alternative medicine utilization in depressed, underserved african american and Hispanic patients in primary care settings

OBJECTIVES

This study seeks to examine the correlates of complementary and alternative medicine (CAM) use in depressed underserved minority populations receiving medical care in primary care settings.

METHODS

A prospective study using interviewer-administered surveys and medical record reviews was conducted at 2 large outpatient primary care clinics providing care primarily to underserved African American and Hispanic individuals located in Los Angeles, California. A total of 2321 patients were screened for depression. Of these, 315 met the Patient Health Questionnaire-9 criteria for mild to severe depression.

RESULTS

Over 57% of the sample reported using CAM sometimes or often (24%) and frequently (33%) for treatment of their depressive symptoms. Controlling for demographic characteristics, lack of health care coverage remained one of the strongest predictors of CAM use. Additionally, being moderately depressed, using psychotherapeutic prescription medications, and poorer self-reported health status were all associated with increased frequency of CAM utilization for treating depression.

CONCLUSIONS

The underserved African American and Hispanic individuals meeting the diagnostic criteria for depression or subsyndromal depression use CAM extensively for symptoms of depression. CAM is used as a substitute for conventional care when access to care is not available or limited. Since CAM is used so extensively for depression, understanding domains, types, and correlates of such use is imperative. This knowledge could be used to design interventions aimed at improving care for depression.

Factors related to vision care in an older adult cohort

PURPOSE

This study provides cross-sectional data on eye care utilization in a community-based adult population.

METHODS

Data are from a questionnaire administered during the 7-year follow-up of the Epidemiology of Hearing Loss Study in 2000 to 2002. Participants in the population-based Beaver Dam Eye Study were eligible for the Epidemiology of Hearing Loss Study, which began in 1997. The primary outcome was self-reported vision testing within the past year.

RESULTS

Subject ages ranged from 55 to 99 years (n = 2433), and 60.4% were female. Fifty-three percent of subjects reported they had their vision tested in the past year. Diabetes was self-reported by 11.5% of subjects, and 70.9% of diabetic participants had their vision tested in the past year. A current hospitalization or health insurance plan was reported by 98.6% of subjects. In multivariate analyses, self-reported factors significantly associated with having a vision test in the past year were female gender (odds ratio [OR] = 1.27; 95% confidence interval [CI] 1.06-1.52), current use of refractive correction for distance (OR = 1.98; 95% CI 1.56-2.52), glaucoma (OR = 3.52; 95% CI 2.37-5.24), cataract surgery (OR = 1.57; 95% CI 1.21-2.03), age-related macular degeneration (ARMD) (OR = 1.74; 95% CI 1.22-2.47), diabetes (OR = 2.46; 95% CI 1.83-3.31), visiting a primary care practitioner for any reason in the past year (OR = 1.72; 95% CI 1.32-2.25), having a hearing test in the past year (OR = 1.79; 95% CI 1.40-2.28), and the cessation of driving because of poor vision (OR = 1.64; 95% CI 1.16-2.52). In participants 65 years of age or older, having private insurance was associated with increased odds (OR = 3.39, 95% CI 1.82-6.31) of vision testing in the past year.

CONCLUSION

This study suggests that chronic ocular conditions, diabetes, health insurance beyond government entitlements, and the use of other healthcare services are associated with increased eye care utilization.

Self-management in African American women with diabetes

PURPOSE

This study describes demographic and medical characteristics, self-efficacy, locus of control, self-management defined by functional status, hemoglobin HbA1c outcomes, and the relationships among these variables based on age group differences (25-44 years, 45-64 years, and 65-84 years) in African American women with type 2 diabetes.

METHODS

Subjects (n = 75) in community medical practices were interviewed to complete a demographic and medical form, the Diabetes Self-efficacy Outcomes Expectancy Questionnaire (DSEQ), the Diabetes Locus of Control Scale, and the Medical Outcomes-Short Form 36 (SF-36). A venous blood sample was taken following the interview. Data were analyzed for the total sample and separately for age groups.

RESULTS

Scores on the self efficacy (DSEQ) and the locus of control (LOC) were above average for all 3 groups. Significant correlations were found among subscales of the LOC, SF-36, and HbA1c. HbA1c scores were abnormally high across groups. Significant group differences were found in duration of diabetes and number of medications used.

CONCLUSIONS

Despite high levels of internal locus of control and self-efficacy and scores indicating good mental, physical, emotional, and social health, self-management among the women was inadequate, as indicated by abnormally high HbA1c levels.

Access to vision care in an urban low-income multiethnic population

OBJECTIVE

This study applied a well-known, recently revised theoretical model of healthcare access and utilization, the Behavioral Model for Vulnerable Populations, to examine the relationship between access to care and utilization of eye care services among a multiethnic, predominately minority sample of residents from low-income public housing.

DESIGN

Population-based, cross-sectional survey of community sample.

SETTING

Urban Public Housing Communities in Los Angeles County, California.

PARTICIPANTS

A geographically defined stratified random sample of 152 residents (86% Latino or African American) 40 years of age and older from three urban public housing communities.

RESULTS

Only 62% of our sample of persons 40 years and older had received an eye examination within the past 2 years. Sixty-one percent of participants reported having vision care coverage. Yet, one out of four respondents claimed that no health care provider had ever told them that they needed an eye-examination. Applying multiple logistic regression and controlling for a number of predisposing, enabling, and need-for-care characteristics, the variables 1) receiving advice from health care providers for eye examination (OR = 3.9, p < 0.01), 2) possessing coverage for eye-care (OR = 3.2, p < 0.01), and 3) having regular and continuity of medical care (OR = 2.4, p < 0.01) remained significant predictors of eye-examination within the past 2 years.

CONCLUSION

This study documents significantly diminished utilization of eye care services relative to recommended guidelines for a low-income, predominately minority sample of residents from public housing communities. We documented no association between presence of diabetes or hypertension and recency of eye examination. Affordability, continuity, and regular sources of care, as well as receiving physician advice, remain the core factors significantly associated with receiving vision care. These results underscore the need for continued efforts to ensure that the medically underserved minority have access to vision care services. These findings also point toward the urgent need for educational and motivational interventions that encourage health care providers serving underserved communities to promote eye examination, particularly among diabetic patients, hypertensive patients, and other individuals at risk for eye-related disease and complications.

Correlates of cervical cancer screening among underserved Hispanic and African-American women

BACKGROUND

Substantial subgroups of American women, specifically those of ethnic minorities, have not been screened for cervical cancer or are not screened at regular intervals. The rates for receipt of female-related cancer screening tests remain far below the goals set forth in Healthy People 2010.

OBJECTIVE

This study applied a well-known, recently revised theoretical model of health care access and utilization, the Behavioral Model for Vulnerable Populations, to examine the correlates of the adherence to cervical cancer screening guidelines among publicly housed Hispanic and African-American women, two of the most vulnerable segments of our population.

METHODS

This study conducted a cross-sectional survey of a community-based random sample of 230 African-American and Latino female heads of household, from a geographically defined area, the three urban public housing communities in Los Angeles County, CA.

RESULTS

Only 62% of our sample had received a screening for cervical cancer within the past year. Yet, 29% of the sample claimed that no health care provider had ever told them that they needed a screening test for cervical cancer. Hispanic and older women are by far less likely to adhere to screening guidelines; in this study, 51% of Hispanics and 22% of African-Americans reported no screening within the last year. Multivariate analysis shows that affordability, continuity of care, and receiving advice from health care providers regarding a Papanicolaou (Pap) smear were significant predictors of up-to-date to cervical cancer screening.

CONCLUSION

This study documents a significant disparity in screening for cervical cancer among underserved minorities, particularly Hispanic, uninsured, and older women. The continuity of obtaining medical services and receiving recommendations from physicians remain the core factors that are significantly associated with obtaining cervical cancer screening. These results underscore the need for continued efforts to ensure that medically underserved minority women have access to cancer screening services.

Neuro-ophthalmology of diabetes

The devastating, blinding effects of diabetic retinopathy have been well publicized. Although individually less common, many neuro-ophthalmologic complications are also associated with diabetes. The vascular effects of diabetes contribute to nonarteritic ischemic optic neuropathy, vasculopathic cranial neuropathies, and strokes affecting both afferent visual function and ocular motility. The neuropathic effects of diabetes primarily affect pupillary function, and the immunosuppressive effects of diabetes predispose to certain infections, such as mucormycosis. Diabetes is also associated with numerous congenital syndromes. This paper reviews the literature published in the past year on the neuro-ophthalmologic effects of diabetes.
