Health Disparities Experienced by People with Disabilities in the United States: A Behavioral Risk Factor Surveillance System Study

The Americans with Disabilities Act became law in 1990; since then research has shown that people with disabilities continue to experience barriers to health care. The purpose of this study was to compare utilization of preventive services, chronic disease rates, and engagement in health risk behaviors of participants with differing severities of disabilities to those without disabilities. This study was a secondary analysis of 2010 data collected in the Behavioral Risk Factor Surveillance System national survey in the United States. Rao Chi square test and logistic regression were employed. Participants with disabilities had significantly higher adjusted odds ratios for all chronic diseases, for physical inactivity, obesity and smoking. They were significantly more likely to participate in some preventive services (flu/pneumonia vaccination, HIV test) and significantly less likely to participate in other preventive services (mammogram, Pap test). Our findings suggest that people with disabilities are less able to fully participate in all preventive services offered.

Effect of a congregation-based intervention on uptake of HIV testing and linkage to care in pregnant women in Nigeria (Baby Shower): a cluster randomised trial

BACKGROUND Few effective community-based interventions exist to increase HIV testing and uptake of antiretroviral therapy (ART) in pregnant women in hard-to-reach resource-limited settings. We assessed whether delivery of an intervention through churches, the Healthy Beginning Initiative, would increase uptake of HIV testing in pregnant women compared with standard health facility referral. METHODS In this cluster randomised trial, we enrolled self-identified pregnant women aged 18 years and older who attended churches in southeast Nigeria. We randomised churches (clusters) to intervention or control groups, stratified by mean annual number of infant baptisms (<80 vs ≥80). The Healthy Beginning Initiative intervention included health education and on-site laboratory testing implemented during baby showers in intervention group churches, whereas participants in control group churches were referred to health facilities as standard. Participants and investigators were aware of church allocation. The primary outcome was confirmed HIV testing. This trial is registered with ClinicalTrials.gov, identifier number NCT 01795261. FINDINGS Between Jan 20, 2013, and Aug 31, 2014, we enrolled 3002 participants at 40 churches (20 per group). 1309 (79%) of 1647 women attended antenatal care in the intervention group compared with 1080 (80%) of 1355 in the control group. 1514 women (92%) in the intervention group had an HIV test compared with 740 (55%) controls (adjusted odds ratio 11·2, 95% CI 8·77-14·25; p<0·0001). INTERPRETATION Culturally adapted, community-based programmes such as the Healthy Beginning Initiative can be effective in increasing HIV screening in pregnant women in resource-limited settings.

Culture, Caregiving, and Health: Exploring the Influence of Culture on Family Caregiver Experiences

Ethnic minorities are expected to experience a greater demand for family caregiving than non-Latino Whites due to their projected population growth. Although the consensus of researchers on caregiving and culture finds that the caregiving experience differs significantly among cultural/ethnic groups, the question remains as to how cultural values and norms influence the caregiver experiences. We conducted an interpretative, phenomenological qualitative analysis of focus group transcripts from four groups (African American, Asian American, Hispanic American, and European American) for cultural influences on caregiving. Data were collected in Nevada between December 7, 2009, and August 20, 2010. Thirty-five caregivers participated in this study. We found commonalities among all of the cultural/ethnic groups in their experiences of the difficulties of caregiving. However, there were some significant differences in the cultural values and norms that shaped the caregiving experience. We categorized these differences as: (a) cultural embeddedness of caregiving, (b) cultural determinants of caregiving responsibilities or taxonomy of caregiving, and (c) cultural values and norms underlying the decision to provide care. The significance of this study is that it highlights the culturally perceived mandate to provide care in the African, Asian, and Hispanic American cultures.

Linkage to care early infant diagnosis and perinatal transmission among infants born to HIV-infected Nigerian mothers: Evidence from the Healthy Beginning Initiative.

Background:In 2014, Nigeria accounted for 33% of all new childhood HIV infections that occurred among the 22 Global Plan priority countries where 80% of HIV-infected women reside. Even with a vertical HIV transmission rate of 27%, only 6% of infants born to HIV-infected women in Nigeria receive early infant diagnosis (EID). This article reports rates of antiretroviral prophylaxis, EID, and mother-to-child transmission in a congregation-based Healthy Beginning Initiative (HBI) designed to increase HIV testing among pregnant women in southeast Nigeria. Methods:This is a nested cohort study of HIV-exposed infants (HEI) within the HBI trial originally designed as a 2-arm cluster randomized trial. HIV-infected mothers and infants were followed between January 2013 and August 2014. Results:Across both arms of the study, 72 HIV-infected women delivered 69 live infants (1 set of twins) and 4 had miscarriages. Of the 69 live-born HEI, HIV status was known for 71% (49/69), 16% (11/69) died before sample collection, and 13% (9/69) were lost to follow-up. Complete information was available for 84% of HEI (58/69), of which 64% (37/58) received antiretroviral prophylaxis. Among the 49 infants tested for HIV, 88% (43/49) received EID within 2 months and 12% (6/49) received antibody testing after 18 months. The mother-to-child transmission rate was 8.2% (4/49). Conclusions:EID was higher and HIV transmission rate was lower among the HBI participants compared to reported rates in 2014. However, further progress is needed to achieve goals of elimination of infant HIV infection.

Accommodations for Patients with Disabilities in Primary Care: A Mixed Methods Study of Practice Administrators

Structural barriers that limit access to health care services for people with disabilities have been identified through qualitative studies; however, little is known about how patients with disabilities are accommodated in the clinical setting when a structural barrier is encountered. The purpose of this study was to identify how primary care medical practices in the United States accommodated people with disabilities when a barrier to service is encountered. Primary care practice administrators from the medical management organization were identified through the organization’s website. Sixty-three administrators from across the US participated in this study. Practice administrators reported that patients were examined in their wheelchairs (76%), that parts of the exam where skipped when a barrier was encountered (44%), that patients were asked to bring someone with them (52.4%) or that patients were refused treatment due to an inaccessible clinic (3.2%). These methods of accommodation would not be in compliance with requirements of the Americans with Disabilities Act. There was not a significant difference (p>0.05) in accommodations for patients with disabilities between administrators who could describe the application of the ADA to their clinic and those who could not. Practice administrators need a comprehensive understanding of the array of challenges encountered by patients with disabilities throughout the health care process and of how to best accommodate patients with disabilities in their practice.

Ebola Outbreak in Nigeria: Increasing Ebola Knowledge of Volunteer Health Advisors

In many low-income countries, volunteer health advisors (VHAs) play an important role in disseminating information, especially in rural or hard-to-reach locations. When the world’s largest outbreak of Ebola virus disease (EVD) occurred in 2014, a majority of cases were concentrated in the West African countries of Guinea, Liberia, and Sierra Leone. Twenty cases were reported in Nigeria initially and there was a need to rapidly disseminate factual information on Ebola virus. In southeast Nigeria, a group of VHAs was being used to implement the Healthy Beginning Initiative [HBI], a congregation based intervention to increase HIV testing among pregnant women and their male partners. The purpose of this study was to assess the baseline and post EVD training knowledge of VHAs during the outbreak in Nigeria. In September 2014, 59 VHAs attending a HBI training workshop in the Enugu State of Nigeria participated in an Ebola awareness training session. Participants completed a 10-item single-answer questionnaire that assessed knowledge of Ebola epidemiology, symptoms, transmission, prevention practices, treatment and survival prior to the Ebola awareness training. After the training, the VHAs repeated the questionnaire. Answers to pre and post questionnaires were analyzed using paired t-tests. Multiple linear regression was used to examine the relationship between pre and post total questionnaire scores and age, education, current location and employment. The average pre-test score was 7.3 and average post-test score was 7.8 which was a significant difference (t=-2.5, p=0.01). Prior to the training, there was a significant difference in Ebola knowledge based on the VHAs education only (p<0.01). After training, education was no longer significant for Ebola knowledge. Existing community health programs can be used as a platform to train VHAs in times of epidemics for quick dissemination of vital health information in areas lacking adequate health infrastructure and personnel.

Barriers to HIV Testing Among Young Men Who Have Sex With Men (MSM): Experiences from Clark County, Nevada

Clark County, Nevada had a 52% increase in newly diagnosed HIV infections in young people age 13-24 with 83% of the new diagnoses in this age group being men who have sex with men (MSM). HIV testing and counseling is critical for HIV prevention, care and treatment, yet young people are the least likely to seek HIV testing. The purpose of this study was to identify barriers and facilitators to HIV testing experienced by young MSM in Clark County, Nevada. We conducted a qualitative focus group discussion to identify barriers and facilitators to HIV testing among eleven young MSM in March, 2015. The primary barrier to HIV testing identified by the group was a lack of awareness or knowledge about testing for HIV. Other barriers within the person included: fear of results, fear of rejection, and fear of disclosure. Barriers identified within the environment included: access issues, stigma, and unfriendly test environments for young people. In addition to increasing awareness, intervention to increase HIV testing among MSM young people should incorporate access to testing in environments where the adolescents are comfortable and which reduces stigma. HIV testing sites should be convenient, accessible and young person/gay friendly.

Why are children still being infected with HIV? Impact of an integrated public health and clinical practice intervention on mother-to-child HIV transmission in Las Vegas, Nevada, 2007–2012

Background: During a 9 months period, September 2005 through June 2006, Nevada documented six cases of pediatric HIV acquired through mother to child transmission. Subsequently, a community based approach to the care of women and children living with or exposed to HIV was implemented. Subjects and Methods: A detailed review of mother infant pairs where HIV transmission occurred was performed to identify missed opportunities for prevention of mother to child HIV transmission. An intervention program was developed and implemented using the six step process. Data were collected prospectively over a 6 years period (2007–2012) and were evaluated for six core outcomes measures: (1) adequacy of prenatal care (2) HIV diagnoses of expectant mothers prior to delivery (3) appropriate use of antiretroviral (ARV) therapy before delivery (4) appropriate use of cesarean section for delivery (5) adequacy of zidovudine prophylaxis to newborn (6) HIV transmission rate. Results: Twenty six infants were born to HIV infected mothers from July 2005 to June 2006 with 6 documented infections. One hundred and five infants were born to HIV infected mothers from January 2007 to December 2012. Postimplementation, adequacy of prenatal care increased from 58% (15/26) to 85% (89/105); appropriate use of ARV therapy before delivery increased from 73% (19/26) to 86% (90/105); cesarean section as the method for delivery increased from 62% (16/26) to 74% (78/105); adequacy of zidovudine prophylaxis to newborn increased from 54% (14/26) to 87% (91/105). HIV transmission rate dropped from 23% (6/26) to 0%. Conclusion: Integrating public health and clinical services in the care of HIV infected pregnant women and exposed infants leads to better coordination of care and improved quality of care.

Brief Report: Geographical Variation in Prevalence of Cryptococcal Antigenemia Among Hiv-infected, Treatment-naive Patients in Nigeria

Objective:Worldwide, HIV-associated cryptococcal meningitis affects approximately 1 million persons and causes 600,000 deaths each year mostly in sub-Saharan Africa. Limited data exist on cryptococcal meningitis and antigenemia in Nigeria, and most studies are geographically restricted. We determined the prevalence of cryptococcal antigenemia (CrAg) among HIV-infected, treatment-naive individuals in Nigeria. Design/Methods:This was a retrospective, cross-sectional study across 4 geographic regions in Nigeria. We performed CrAg testing using a lateral flow immunoassay on archived whole-blood samples collected from HIV-infected participants at US Presidents Emergency Plan for AIDS Relief (PEPFAR)-supported sites selected to represent the major geographical and ethnic diversity in Nigeria. Eligible samples were collected from consenting patients (>15 years) naive to antiretroviral therapy with CD4+ count less than 200 cells per cubic millimeter and were stored in an −80°C freezer. Results:A total of 2752 stored blood samples were retrospectively screened for CrAg. Most of the samples were from participants aged 30–44 years (57.6%), and 1570 (57.1%) were from women. The prevalence of CrAg positivity in specimens with CD4 <200 cells per cubic millimeter was 2.3% (95% confidence interval: 1.8% to 3.0%) and varied significantly across the 4 regions (P < 0.001). At 4.4% (3.2% to 5.9%), the South East contained the highest prevalence. Conclusions:The significant regional variation in CrAg prevalence found in Nigeria should be taken into consideration as plans are made to integrate routine screening into clinical care for HIV-infected patients.

Interventions to Reduce Loss to Follow-up During All Stages of the HIV Care Continuum in Sub-Saharan Africa: A Systematic Review

The continuum of care for successful HIV treatment includes HIV testing, linkage, engagement in care, and retention on antiretroviral therapy (ART). Loss to follow-up (LTFU) is a significant disruption to this pathway and a common outcome in sub-Saharan Africa. This review of literature identified interventions that have reduced LTFU in the HIV care continuum. A search was conducted utilizing terms that combined the disease state, stages of the HIV care continuum, interventions, and LTFU in sub-Saharan Africa and articles published between January 2010 and July 2015. Thirteen articles were included in the final review. Use of point of care CD4 testing and community-supported programs improved linkage, engagement, and retention in care. There are few interventions directed at LTFU and none that span across the entire continuum of HIV care. Further research could focus on devising programs that include a series of interventions that will be effective through the entire continuum.ResumenLa continuidad de la atención para el éxito del tratamiento del VIH incluye la prueba del VIH, la vinculación y el compromiso en el cuidado y mantenimiento de la terapia antirretroviral (TAR). Las pérdidas durante el seguimiento (LTFU) es una alteración significativa de esta vía y un resultado común en el África subsahariana. Esta revisión de la literatura identificó intervenciones que han reducido LTFU en el continuo de la atención del VIH. Se realizó una búsqueda utilizando términos que combinaban el estado de la enfermedad, las etapas del continuo de la atención del VIH, las intervenciones y LTFU en el África subsahariana y los artículos publicados entre enero de 2010 y julio de 2015. Trece artículos fueron incluidos en la revisión final. El uso del punto de atención pruebas de CD4 y los programas apoyados por la comunidad mejorar la articulación, compromiso, y la retención de los pacientes. Hay pocas intervenciones dirigidas a LTFU y ninguno que se extienden a lo largo de todo el continuo de la atención del VIH. La investigación adicional podría centrarse en la elaboración de programas que incluyen una serie de intervenciones que serán efectivas a través de toda la cadena.
