Healthcare factors associated with the risk of antepartum and intrapartum stillbirth in migrants in Western Australia (2005-2013): A retrospective cohort study

BACKGROUND

Migrant women, especially from Indian and African ethnicity, have a higher risk of stillbirth than native-born populations in high-income countries. Differential access or timing of ANC and the uptake of other services may play a role. We investigated the pattern of healthcare utilisation among migrant women and its relationship with the risk of stillbirth (SB)-antepartum stillbirth (AnteSB) and intrapartum stillbirth (IntraSB)-in Western Australia (WA).

METHODS AND FINDINGS

A retrospective cohort study using de-identified linked data from perinatal, birth, death, hospital, and birth defects registrations through the WA Data Linkage System was undertaken. All (N = 260,997) non-Indigenous births (2005-2013) were included. Logistic regression analysis was used to estimate odds ratios and 95% CI for AnteSB and IntraSB comparing migrant women from white, Asian, Indian, African, Māori, and 'other' ethnicities with Australian-born women controlling for risk factors and potential healthcare-related covariates. Of all the births, 66.1% were to Australian-born and 33.9% to migrant women. The mean age (years) was 29.5 among the Australian-born and 30.5 among the migrant mothers. For parity, 42.3% of Australian-born women, 58.2% of Indian women, and 29.3% of African women were nulliparous. Only 5.3% of Māori and 9.2% of African migrants had private health insurance in contrast to 43.1% of Australian-born women. Among Australian-born women, 14% had smoked in pregnancy whereas only 0.7% and 1.9% of migrants from Indian and African backgrounds, respectively, had smoked in pregnancy. The odds of AnteSB was elevated in African (odds ratio [OR] 2.22, 95% CI 1.48-2.13, P < 0.001), Indian (OR 1.64, 95% CI 1.13-2.44, P = 0.013), and other women (OR 1.46, 95% CI 1.07-1.97, P = 0.016) whereas IntraSB was higher in African (OR 5.24, 95% CI 3.22-8.54, P < 0.001) and 'other' women (OR 2.18, 95% CI 1.35-3.54, P = 0.002) compared with Australian-born women. When migrants were stratified by timing of first antenatal visit, the odds of AnteSB was exclusively increased in those who commenced ANC later than 14 weeks gestation in women from Indian (OR 2.16, 95% CI 1.18-3.95, P = 0.013), Māori (OR 3.03, 95% CI 1.43-6.45, P = 0.004), and 'other' (OR 2.19, 95% CI 1.34-3.58, P = 0.002) ethnicities. With midwife-only intrapartum care, the odds of IntraSB for viable births in African and 'other' migrants (combined) were more than 3 times that of Australian-born women (OR 3.43, 95% CI 1.28-9.19, P = 0.014); however, with multidisciplinary intrapartum care, the odds were similar to that of Australian-born group (OR 1.34, 95% CI 0.30-5.98, P = 0.695). Compared with Australian-born women, migrant women who utilised interpreter services had a lower risk of SB (OR 0.51, 95% CI 0.27-0.96, P = 0.035); those who did not utilise interpreters had a higher risk of SB (OR 1.20, 95% CI 1.07-1.35, P < 0.001). Covariates partially available in the data set comprised the main limitation of the study.

CONCLUSION

Late commencement of ANC, underutilisation of interpreter services, and midwife-only intrapartum care are associated with increased risk of SB in migrant women. Education to improve early engagement with ANC, better uptake of interpreter services, and the provision of multidisciplinary-team intrapartum care to women specifically from African and 'other' backgrounds may reduce the risk of SB in migrants.

Gaps in the HIV diagnosis and care cascade for migrants in Australia, 2013-2017: A cross-sectional study

BACKGROUND

Globally, few studies compare progress toward the Joint United Nations Program on HIV/AIDS (UNAIDS) Fast-Track targets among migrant populations. Fast-Track targets are aligned to the HIV diagnosis and care cascade and entail achieving 90-90-90 (90% of people living with HIV [PLHIV] diagnosed, 90% of those diagnosed on treatment, and 90% of those on treatment with viral suppression [VS]) by 2020 and 95-95-95 by 2030. We compared cascades between migrant and nonmigrant populations in Australia.

METHODS AND FINDINGS

We conducted a serial cross-sectional survey for HIV diagnosis and care cascades using modelling estimates for proportions diagnosed combined with a clinical database for proportions on treatment and VS between 2013-2017. We estimated the number of PLHIV and number diagnosed using New South Wales (NSW) and Victorian (VIC) data from the Australian National HIV Registry. Cascades were stratified by migration status, sex, HIV exposure, and eligibility for subsidised healthcare in Australia (reciprocal healthcare agreement [RHCA]). We found that in 2017, 17,760 PLHIV were estimated in NSW and VIC, and 90% of them were males. In total, 90% of estimated PLHIV were diagnosed. Of the 9,391 who were diagnosed and retained in care, most (85%; n = 8,015) were males. We excluded 38% of PLHIV with missing data for country of birth, and 41% (n = 2,408) of eligible retained PLHIV were migrants. Most migrants were from Southeast Asia (SEA; 28%), northern Europe (12%), and eastern Asia (11%). Most of the migrants and nonmigrants were males (72% and 83%, respectively). We found that among those retained in care, 90% were on antiretroviral therapy (ART), and 95% of those on ART had VS (i.e., 90-90-95). Migrants had larger gaps in their HIV diagnosis and care cascade (85-85-93) compared with nonmigrants (94-90-96). Similarly, there were larger gaps among migrants reporting male-to-male HIV exposure (84-83-93) compared with nonmigrants reporting male-to-male HIV exposure (96-92-96). Large gaps were also found among migrants from SEA (72-87-93) and sub-Saharan Africa (SSA; 89-93-91). Migrants from countries ineligible for RHCA had lower cascade estimates (83-85-92) than RHCA-eligible migrants (96-86-95). Trends in the HIV diagnosis and care cascades improved over time (2013 and 2017). However, there was no significant increase in ART coverage among migrant females (incidence rate ratio [IRR]: 1.03; 95% CI 0.99-1.08; p = 0.154), nonmigrant females (IRR: 1.01; 95% CI 0.95-1.07; p = 0.71), and migrants from SEA (IRR: 1.03; 95% CI 0.99-1.07; p = 0.06) and SSA (IRR: 1.03; 95% CI 0.99-1.08; p = 0.11). Additionally, there was no significant increase in VS among migrants reporting male-to-male HIV exposure (IRR: 1.02; 95% CI 0.99-1.04; p = 0.08). The major limitation of our study was a high proportion of individuals missing data for country of birth, thereby limiting migrant status categorisation. Additionally, we used a cross-sectional instead of a longitudinal study design to develop the cascades and used the number retained as opposed to using all individuals diagnosed to calculate the proportions on ART.

CONCLUSIONS

HIV diagnosis and care cascades improved overall between 2013 and 2017 in NSW and VIC. Cascades for migrants had larger gaps compared with nonmigrants, particularly among key migrant populations. Tracking subpopulation cascades enables gaps to be identified and addressed early to facilitate achievement of Fast-Track targets.

Trends in the Use of Stereotactic Body Radiotherapy for Treatment of Prostate Cancer in the United States

IMPORTANCE

Stereotactic body radiotherapy is a hypofractionated, cost-effective treatment option for localized prostate cancer.

OBJECTIVE

To characterize US national trends and the clinical and socioeconomic factors associated with the use of stereotactic body radiotherapy in prostate cancer.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study used data collected by the National Cancer Database to assess the clinical and socioeconomic factors among 106 926 men diagnosed as having prostate cancer from 2010 to 2015 who underwent definitive radiotherapy and the trends in the use of this therapy. The initial analysis was performed between January and February 2018, with final updates performed August 2019.

EXPOSURE

Stereotactic body radiotherapy, defined as 5 fractions of radiotherapy.

MAIN OUTCOMES AND MEASURES

Temporal trends and clinical and sociodemographic factors associated with stereotactic body radiotherapy use.

RESULTS

In total, 106 926 patients diagnosed as having localized prostate cancer between 2010 and 2015 and receiving definitive radiotherapy were identified. White patients composed 77.3% of this cohort, whereas black patients composed 18.7%. Government-issued insurance was used by 61.2% of patients. More than 80% of patients had a Charlson-Deyo Comorbidity Index score of 0 (range, 0 to ≥3, with lower numbers indicating fewer comorbidities). In the study population, 25.7% had low-risk disease; 26.3%, favorable intermediate-risk disease; 23.3%, unfavorable intermediate-risk disease; and 24.7%, high-risk disease. The proportion of patients who underwent radiotherapy and received stereotactic body radiotherapy (a total of 5395 patients) increased from 3.1% in 2010 to 7.2% in 2015 (odds ratio, 0.36; 95% CI, 0.33-0.40; P < .001). Among the entire cohort, patients received a median dose of 36.25 Gy (range, 30.00-50.00 Gy). Androgen deprivation therapy use increased significantly as disease risk level increased among all patients receiving radiotherapy (9.5% with low risk to 76.6% with high risk; P = .02) and among those receiving stereotactic body radiotherapy (4.1% with low risk to 33.2% with high risk; P = .04) or not receiving stereotactic body radiotherapy (9.9% with low risk to 77.6% with high risk; P = .04). Patients treated at an academic center, living in an urban area, or possessing higher incomes and those who were healthier, white individuals, or were diagnosed as having lower-risk prostate cancer had higher odds of receiving stereotactic body radiotherapy.

CONCLUSIONS AND RELEVANCE

This study found that stereotactic body radiotherapy use in prostate cancer more than doubled from 2010 to 2015 but accounted for less than 10% of all patients undergoing radiotherapy. Androgen deprivation therapy use increased with disease risk among patients overall, regardless of receiving stereotactic body radiotherapy. Socioeconomic and clinical determinants of stereotactic body radiotherapy included risk category, Charlson-Deyo Comorbidity Index score, facility type and location, income, race/ethnicity, and year of diagnosis. These results are hypothesis generating; further studies evaluating potential disparities in stereotactic body radiotherapy use in localized prostate cancer are warranted.

Closing the inequality gaps in reproductive, maternal, newborn and child health coverage: slow and fast progressors

Introduction

Universal Health Coverage (UHC) is a critical goal under the Sustainable Development Goals (SDGs) for health. Achieving this goal for reproductive, maternal, newborn and child health (RMNCH) service coverage will require an understanding of national progress and how socioeconomic and demographic subgroups of women and children are being reached by health interventions.

Methods

We accessed coverage databases produced by the International Centre for Equity in Health, which were based on reanalysis of Demographic and Health Surveys, Multiple Indicator Cluster Surveys and Reproductive and Health Surveys. We limited the data to 58 countries with at least two surveys since 2008. We fitted multilevel linear regressions of coverage of RMNCH, divided into four main components-reproductive health, maternal health, child immunisation and child illness treatment-to estimate the average annual percentage point change (AAPPC) in coverage for the period 2008-2017 across these countries and for subgroups defined by maternal age, education, place of residence and wealth quintiles. We also assessed change in the pace of coverage progress between the periods 2000-2008 and 2008-2017.

Results

Progress in RMNCH coverage has been modest over the past decade, with statistically significant AAPPC observed only for maternal health (1.25, 95% CI 0.90 to 1.61) and reproductive health (0.83, 95% CI 0.47 to 1.19). AAPPC was not statistically significant for child immunisation and illness treatment. Progress, however, varied largely across countries, with fast or slow progressors spread throughout the low-income and middle-income groups. For reproductive and maternal health, low-income and lower middle-income countries appear to have progressed faster than upper middle-income countries. For these two components, faster progress was also observed in older women and in traditionally less well-off groups such as non-educated women, those living in rural areas or belonging to the poorest or middle wealth quintiles than among groups that are well off. The latter groups however continue to maintain substantially higher coverage levels over the former. No acceleration in RMNCH coverage was observed when the periods 2000-2008 and 2008-2017 were compared.

Conclusion

At the dawn of the SDGs, progress in coverage in RMNCH remains insufficient at the national level and across equity dimensions to accelerate towards UHC by 2030. Greater attention must be paid to child immunisation to sustain the past gains and to child illness treatment to substantially raise its coverage across all groups.

Association of the Robert Wood Johnson Foundations' social determinants of health and Medicare hospitalisations for ischaemic strokes: a cross-sectional data analysis

Objective

Social determinants of health (SDH) have previously demonstrated to be important risk factors in determining health outcomes. To document whether the SDH are associated with hospitalisations for ischaemic stroke.

Methods

This cross-sectional study examines data from fiscal year 2015. Patients from the national Medicare 100% Inpatient Limited Dataset were linked with SDH measures from the Robert Wood Johnson Foundation (RWJF) County Health Rankings. Medicare patients were included in the study group if they had either an admitting or primary diagnosis of ischaemic stroke. Counties without RWJF data were excluded from the study. Ischaemic strokes were compared with all other hospitalisations associated with characteristics of the SDH measures and benchmarked to above or below their respective national median. Estimates were performed with nested logistic regression.

Results

Approximately 256 766 Medicare patients had ischaemic stroke hospitalisations compared with all other Medicare patients (n=6 386 180) without ischaemic stroke hospitalisations while 30 853 patients were excluded due to residence in US territories. Significant factors included air pollution exceeding the national median (OR 1.06; 95% CI 1.05 to 1.07), per cent of children in single parent households exceeding the national median, (OR 1.02; 95% CI 1.01 to 1.03), violent crime rates exceeding the national median, (OR 1.02; 95% CI 1.01 to 1.03) and per cent smoking exceeding the national median, (OR 1.02; 95% CI 1.01 to 1.03).

Conclusions

When cross-sectional SDH are benchmarked to national median for ischaemic stroke hospitalisations and compared with all-cause hospitalisations, the effects remain significant. Further research on the longitudinal effects of the SDH and cardiovascular health, particularly disease-specific outcomes, is needed.

Race and socioeconomic differences associated with endovascular peripheral vascular interventions for newly diagnosed claudication

BACKGROUND

Despite guidelines cautioning against the use of endovascular peripheral vascular interventions (PVI) for claudication, more than 1.3 million PVI procedures are performed annually in the United States. We aimed to describe national rates of PVI for claudication, and identify patient and county-level risk factors associated with a high rate of PVI.

METHODS

We used the Medicare claims database to identify all Medicare beneficiaries with a new diagnosis of claudication between January 2015 and June 2017. A hierarchical logistic regression model accounting for patient age, sex, comorbidities; county region and setting; and a patient race-county median income interaction was used to assess the associations of race and income with a high PVI rate.

RESULTS

We identified 1,201,234 patients with a new diagnosis of claudication for analysis. Of these, 15,227 (1.27%) underwent a PVI. Based on hierarchical logistic regression accounting for patient and county-level factors, black patients residing in low-income counties had a significantly higher odds of undergoing PVI than their white counterparts (odds ratio [OR], 1.30; 95% confidence interval [CI], 1.20-1.40), whereas the odds of PVI for black versus white patients was similar in high-income counties (OR, 1.06; 95% CI, 0.99-1.14). PVI rates were higher for low versus high-income counties in both the black (OR, 1.46; 95% CI, 1.31-1.64) and white (OR, 1.19; 95% CI, 1.12-1.27) groups. There were no significant associations of Hispanic, Asian, North American native, or other races with PVI in either low- or high-income counties after risk adjustment (all P ≥ .09).

CONCLUSIONS

In the Medicare population, the mean rate of PVI of 12.7 per 1000 claudication patients varies significantly based on race and income. Our data suggest there are racial and socioeconomic differences in the treatment of claudication across the United States.

Ethnic disparities in cancer incidence and survival among the oldest old in the United States

Objective: To examine potential ethnic disparities in cancer incidence and survival rates among the oldest old using data from the SEER Program.Design: Cases diagnosed with one of the leading four cancer sites (lung and bronchus, colon and rectum, female breast, prostate) and four cancer sites (stomach, liver and intrahepatic bile duct, gallbladder, and cervical) that disproportionally affect Hispanics were reported to one of 18 SEER registries. Differences in cancer incidence were examined for cases aged ≥85 years diagnosed during the most recent 5-year time period (2009-2013) and, to examine changes over time, from 1992 to 2013. Five-year relative cancer survival probability was examined for Hispanics and non-Hispanics aged ≥85 years diagnosed 2006-2012.Results: From 2009 to 2013, non-Hispanics aged ≥85 years had higher incidence rates compared to Hispanics for colon and rectum, lung and bronchus, female breast, and prostate cancers. Five-year survival probability for cancers of all stages combined was higher for non-Hispanics than Hispanics in this age group. However, Hispanics had higher survival probability of colon and rectum and lung and bronchus cancers diagnosed at regional (colon and rectum: 67.2% vs. 60.5%; lung and bronchus: 15.9% vs. 12.7%) and distant (colon and rectum: 5.4% vs. 3.8%; lung and bronchus: 2.8% vs. 2.2%) stages than non-Hispanics, respectively.Conclusion: Ethnic differences in cancer incidence and survival probability exist for the ≥85 population. Continued efforts are needed to understand and reduce ethnic disparities in cancer prevention and treatment for this population.

Assisted reproductive technology use in the United States: a population assessment

OBJECTIVE

To study social and demographic differentiation of assisted reproduction technology (ART) use at the population level in the United States.

DESIGN

Population-based study.

SETTING

Not applicable.

PATIENT(S)

Women 15-49 years old in the American Community Survey and National Vital Statistics Birth Certificate data from 2010-2017.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

Birth rate after ART by major sociodemographic categories and likelihood of having an ART birth.

RESULT(S)

Net of education, age, period, and marital status, the incidence rates of ART births are lower for black women (0.57 times; 95% CI, 0.52-0.62) and Hispanic women (0.67 times; 95% CI, 0.57-0.62) relative to white women's rates; for Asian women, the incidence rates are 1.21 times that of white women's rates. Further, the incidence rates of ART births are higher for women with more than a 4-year degree (2.08 times; 95% CI, 1.90-2.27) relative to women with a 4-year degree, and are lower for women with less education. Women who are married have an incidence rate of ART that is 5.72 times (95% CI, 5.37-6.09) that of unmarried women. The incidence rates for 2013-2016 are statistically significantly higher than for 2010 by a factor of 1.16 (95% CI, 1.02-1.31), 1.16 (95% CI, 1.03-1.31), 1.27 (95% CI, 1.12-1.43), and 1.51 (95% CI, 1.43-1.82), respectively. The educational differences in ART exist across all age groups from 20 to 49, but are the largest among the 35-39 and 40-44 age groups.

CONCLUSION(S)

Large differences in the risk of an ART birth and the proportion of births and the total fertility rate due to ART exist across period, age, race, education, and marital status groups in the United States. Current measures of ART births may disguise an unmet need for ART.

Clinical Practice Patterns in Temporary Mechanical Circulatory Support for Shock in the Critical Care Cardiology Trials Network (CCCTN) Registry

BACKGROUND

Temporary mechanical circulatory support (MCS) devices provide hemodynamic assistance for shock refractory to pharmacological treatment. Most registries have focused on single devices or specific etiologies of shock, limiting data regarding overall practice patterns with temporary MCS in cardiac intensive care units.

METHODS

The CCCTN (Critical Care Cardiology Trials Network) is a multicenter network of tertiary CICUs in North America. Between September 2017 and September 2018, each center (n=16) contributed a 2-month snapshot of consecutive medical CICU admissions.

RESULTS

Of the 270 admissions using temporary MCS, 33% had acute myocardial infarction-related cardiogenic shock (CS), 31% had CS not related to acute myocardial infarction, 11% had mixed shock, and 22% had an indication other than shock. Among all 585 admissions with CS or mixed shock, 34% used temporary MCS during the CICU stay with substantial variation between centers (range: 17%-50%). The most common temporary MCS devices were intraaortic balloon pumps (72%), Impella (17%), and veno-arterial extracorporeal membrane oxygenation (11%), although intraaortic balloon pump use also varied between centers (range: 40%-100%). Patients managed with intraaortic balloon pump versus other forms of MCS (advanced MCS) had lower Sequential Organ Failure Assessment scores and less severe metabolic derangements. Illness severity was similar at high- versus low-MCS utilizing centers and at centers with more advanced MCS use.

CONCLUSIONS

There is wide variation in the use of temporary MCS among patients with shock in tertiary CICUs. While hospital-level variation in temporary MCS device selection is not explained by differences in illness severity, patient-level variation appears to be related, at least in part, to illness severity.

Progress in cancer survival, mortality, and incidence in seven high-income countries 1995-2014 (ICBP SURVMARK-2): a population-based study

BACKGROUND

Population-based cancer survival estimates provide valuable insights into the effectiveness of cancer services and can reflect the prospects of cure. As part of the second phase of the International Cancer Benchmarking Partnership (ICBP), the Cancer Survival in High-Income Countries (SURVMARK-2) project aims to provide a comprehensive overview of cancer survival across seven high-income countries and a comparative assessment of corresponding incidence and mortality trends.

METHODS

In this longitudinal, population-based study, we collected patient-level data on 3·9 million patients with cancer from population-based cancer registries in 21 jurisdictions in seven countries (Australia, Canada, Denmark, Ireland, New Zealand, Norway, and the UK) for seven sites of cancer (oesophagus, stomach, colon, rectum, pancreas, lung, and ovary) diagnosed between 1995 and 2014, and followed up until Dec 31, 2015. We calculated age-standardised net survival at 1 year and 5 years after diagnosis by site, age group, and period of diagnosis. We mapped changes in incidence and mortality to changes in survival to assess progress in cancer control.

FINDINGS

In 19 eligible jurisdictions, 3 764 543 cases of cancer were eligible for inclusion in the study. In the 19 included jurisdictions, over 1995-2014, 1-year and 5-year net survival increased in each country across almost all cancer types, with, for example, 5-year rectal cancer survival increasing more than 13 percentage points in Denmark, Ireland, and the UK. For 2010-14, survival was generally higher in Australia, Canada, and Norway than in New Zealand, Denmark, Ireland, and the UK. Over the study period, larger survival improvements were observed for patients younger than 75 years at diagnosis than those aged 75 years and older, and notably for cancers with a poor prognosis (ie, oesophagus, stomach, pancreas, and lung). Progress in cancer control (ie, increased survival, decreased mortality and incidence) over the study period was evident for stomach, colon, lung (in males), and ovarian cancer.

INTERPRETATION

The joint evaluation of trends in incidence, mortality, and survival indicated progress in four of the seven studied cancers. Cancer survival continues to increase across high-income countries; however, international disparities persist. While truly valid comparisons require differences in registration practice, classification, and coding to be minimal, stage of disease at diagnosis, timely access to effective treatment, and the extent of comorbidity are likely the main determinants of patient outcomes. Future studies are needed to assess the impact of these factors to further our understanding of international disparities in cancer survival.

Anticoagulation therapy patterns for acute treatment of venous thromboembolism in GARFIELD-VTE patients

BACKGROUND

Parenteral anticoagulants and vitamin K antagonists (VKAs) have constituted the cornerstone of venous thromboembolism (VTE) treatment. Meanwhile, direct oral anticoagulants (DOACs) provide physicians with an alternative. The Global Anticoagulant Registry in the FIELD (GARFIELD)-VTE observes real-world treatment practices.

OBJECTIVES

Describe initial anticoagulation (AC) treatment patterns in VTE patients who received parenteral AC, VKAs, and/or DOACs within ±30 days of diagnosis.

METHODS

VTE patients were categorized into parenteral AC only, parenteral AC with transition to VKA, VKA only, parenteral AC with transition to DOAC, and DOAC only.

RESULTS

A total of 9647 patients were initiated on AC treatment alone. 4781 (49.6%) patients received DOACs ± parenteral ACs; 3187 (33.0%), VKA ± parenteral ACs; and 1679 (17.4%) parenteral ACs alone. Rivaroxaban was the most frequently used DOAC (79.4%). DOACs were more frequently used in North America/Australia (58.1%), Europe (52.2%), and Asia (47.6%) than in Latin America (29.7%) and the Middle East/South Africa (32.5%). In patients with suspected VTE, most received parenteral AC monotherapy (67.7%). Patients with deep vein thrombosis were more likely to receive DOACs alone than those with pulmonary embolism with or without deep vein thrombosis (36.2% vs 25.9%). Active cancer patients received parenteral AC alone (58.9%), with 25.5% receiving DOAC ± parenteral AC and 12.8% parenteral AC and VKA. A total of 46.5% of pregnant patients received parenteral AC monotherapy, 34.0% were treated with VKA ± parenteral AC, and 19.5% received a DOAC (± parenteral AC).

CONCLUSION

AC treatment patterns vary by patient population, geographic region and site of VTE. Guidelines for AC therapy are not always adhered to.

Childhood Socioeconomic Status and Later Life Cognition: Evidence From the Wisconsin Longitudinal Study

Objectives:This study examined childhood socioeconomic status (SES) as a predictor of later life cognition and the extent to which midlife SES accounts for associations. Methods: Data came from 5,074 participants in the Wisconsin Longitudinal Study. Measures from adolescence included parents' educational attainment, father's occupational status, and household income. Memory and language/executive function were assessed at ages 65 and 72 years. Results: Global childhood SES was a stronger predictor of baseline levels of language/executive function than baseline memory. Associations involving parents' education were reduced in size and by statistical significance when accounting for participants' midlife SES, whereas associations involving parental income and occupational status became statistically nonsignificant. We found no associations between childhood SES and change in cognition. Discussion: Findings contribute to growing evidence that socioeconomic differences in childhood have potential consequences for later life cognition, particularly in terms of the disparate levels of cognition with which people enter later life.

Temporal Trends in Contemporary Use of Ventricular Assist Devices by Race and Ethnicity

BACKGROUND

The proportion of racial/ethnic minorities receiving ventricular assist devices (VADs) has previously been less than expected. It is unclear if trends have changed since the broadening of access to insurance in 2014 and the rapid adoption of VAD technology.

METHODS AND RESULTS

Using the Interagency Registry of Mechanically Assisted Circulatory Support, we analyzed time trends by race/ethnicity for 10 795 patients (white, 67.4%; African-American, 24.8%; Hispanic, 6.3%; Asian, 1.5%) who had a VAD implanted between 2012 and 2015. Linear models were fit to the annual census-adjusted rate of VAD implantation for each racial/ethnic group, stratified by sex and age group. From 2012 to 2015, African-Americans had an increase in the census-adjusted annual rate of VAD implantation per 100 000 (0.26 [95% confidence interval, 0.17-0.34]) while other ethnic groups exhibited no significant changes (white: 0.06 [-0.03 to 0.14]; Hispanic: 0.04 [-0.05 to 0.12]; Asian: 0.04 [-0.04 to 0.13]). Stratified by sex, rates increased in both African-American men and women (P<0.05), but the change in rate was highest among African-American men (men 0.37 [0.28-0.46]; women 0.16 [0.07-0.25]; interaction with sex P=0.004). Stratified by age group, rates increased in African-Americans aged 40 to 69 years and Asians aged 50 to 59 years (P<0.05). The observed differential change in VAD implantation rate by age group was significant among African-Americans (interaction with age, P<0.01) and Asians (interaction with age, P=0.02).

CONCLUSIONS

From 2012 to 2015, VAD implantation rates increased among African-Americans but not other racial/ethnic groups. The greatest increase in rate was observed among middle-aged African-American men, suggesting a decline in racial disparities. Further investigation is warranted to reduce disparities among women and older racial/ethnic minorities.

Heterogeneity in Standard Operating Procedures for Catheter Directed Thrombolysis for Peripheral Arterial Occlusions in The Netherlands: A Nationwide Overview

OBJECTIVE

Catheter directed thrombolysis (CDT) for acute arterial occlusions of the lower extremities is associated with a risk of major bleeding complications. Strict monitoring of vital functions is advised for timely adjustment or discontinuation of thrombolytic treatment. Nevertheless, current evidence on the optimal application of CDT and use of monitoring during CDT is limited. In this study the different standard operating procedures (SOPs) for CDT in Dutch hospitals were compared against a national guideline in a nationwide analysis.

METHODS

SOPs, landmark studies, and national and international guidelines for CDT for acute lower extremity arterial occlusions were compared. The protocols of 34 Dutch medical centres where CDT is performed were assessed. Parameters included contraindications to CDT, co-administration of heparin, thrombolytic agent administration, angiographic control, and patient monitoring.

RESULTS

Thirty-four SOPs were included, covering 94% of medical centres performing CDT in the Netherlands. None of the SOPs had identical contraindications and a strong divergence in relative and absolute grading was found. Heparin and urokinase dosages differed by a factor of five. In 18% of the SOPs heparin co-administration was not mentioned. Angiographic control varied between once every 6 h to once every 24 h. In 76% of the SOPs plasma fibrinogen levels were used for CDT dose adjustments. However, plasma fibrinogen level threshold values for treatment adjustments varied between 2.0 g/L and 0.5 g/L.

CONCLUSION

The SOPs for CDT for acute arterial occlusions of the lower extremities differ greatly on five major operating aspects among medical centres in the Netherlands. None of the SOPs exactly conforms to current national or international guidelines. This study provides direction on how to increase homogeneity in guideline recommendations and to improve guideline adherence in CDT.

Unmet supportive care needs in young adult cancer patients: associations and changes over time. Results from the AYA-Leipzig study

PURPOSE

Coping with cancer at a young adult age (AYA) is a challenge for many patients and raises support needs. We aim to examine unmet supportive care needs and to investigate predictors of and changes in unmet needs over time.

METHODS

We surveyed AYAs (18-39 years at time of diagnosis, diagnosis < 4 years) at two time points (t2 = 12 months after t1) using the Supportive Care Needs Survey (SCNS-SF34) among other validated measures. We conducted multiple hierarchical regressions to identify sociodemographic, medical and psychosocial predictors of unmet needs.

RESULTS

A total of 514 AYAs (386 women) with a mean age of 29.6 years participated at both times. Psychological needs (M_t1 = 35.7; M_t2 = 32.09; p = 0.001) and informational needs (M_t1 = 32.18; M_t2 = 29.04; p = 0.021) were the most often reported unmet needs at both measurements and decreased slightly at t2. All other SCNS domains, except for patient care, remained stable over time. Higher supportive needs were associated with greater levels of effort to cope with the disease at both times in all domains. Older age and female gender were significantly associated with two and one of six domains, respectively, at t1 and t2.

CONCLUSIONS

AYAs reported primarily unmet psychological and informational needs, which were stable over time and indicated that AYAs do not have sufficient access to the support they need. The degree of effort to cope with cancer plays a key role in terms of unmet support needs.

IMPLICATIONS FOR CANCER SURVIVORS

Regular screening for this variable in acute and especially follow-up care settings could pave the way for clinicians to offer more targeted support.

Changes in Perceptions of Discrimination in Health Care in California, 2003 to 2017

IMPORTANCE

Research in the early 2000s in California demonstrated that racial and ethnic minorities, immigrants, and those with limited English proficiency (LEP) experienced high rates of discrimination in health care. Less is known about how patients' perceptions of discrimination in health care have changed since then.

OBJECTIVE

To determine whether perceptions of discrimination in health care have changed overall and for specific vulnerable populations.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used data from the California Health Interview Survey for state residents aged 18 years and older for 2 periods, 2003 to 2005 and 2015 to 2017. χ2 analyses and multivariate logistic regression were performed to compare recent discrimination in health care in late vs early periods controlling for race/ethnicity, poverty level, education, insurance status, usual source of care, self-reported health, and LEP. Additional subanalyses were performed by race/ethnicity, immigrant status, and LEP status. Jackknife replicate weights were provided by the California Health Interview Survey.

EXPOSURE

Survey year was dichotomized as combined 2003 to 2005 and combined 2015 to 2017.

MAIN OUTCOMES AND MEASURES

Survey respondents were identified as having experienced recent discrimination in health care if they responded "yes" to the question, "Was there ever a time when you would have gotten better medical care if you had belonged to a different race or ethnic group?" and reported that this occurred within the last 5 years.

RESULTS

There were 84 088 participants in 2003 to 2005 (51.0% female; 14.7% aged ≥65 years) and 63 242 participants in 2015 to 2017 (51.1% female; 18.0% aged ≥65 years). Rates of recent discrimination in health care decreased from 6.0% to 4.0% (difference, 2.0%; 95% CI, 1.5%-2.5%; P < .001). In adjusted analyses, perceptions of discrimination in health care decreased in 2015 to 2017 compared with 2003 to 2005 (odds ratio [OR], 0.60; 95% CI, 0.53-0.68; P < .001). There was a significant race × period interaction for Latino individuals (OR, 0.58; 95% CI, 0.40-0.83; P = .003) but not for Asian individuals (OR, 0.76; 95% CI, 0.50-1.16; P = .20) or African American individuals (OR, 1.24; 95% CI, 0.76-2.02; P = .40). There was a significant immigrant status × period interaction (OR, 0.55; 95% CI, 0.44-0.69; P < .001) and LEP status × period interaction (OR, 0.67; 95% CI, 0.51-0.89; P < .001).

CONCLUSIONS AND RELEVANCE

This study suggests that perceptions of discrimination in health care in California decreased between 2003 to 2005 and 2015 to 2017 among Latino individuals, immigrants, and those with LEP. African American participants reported consistently high rates of discrimination, indicating that interventions targeting health care discrimination are still necessary.

Care practices and neonatal survival in 52 neonatal intensive care units in Telangana and Andhra Pradesh, India: A cross-sectional study

BACKGROUND

The Indian government supports both public- and private-sector provision of hospital care for neonates: neonatal intensive care is offered in public facilities alongside a rising number of private-for-profit providers. However, there are few published reports about mortality levels and care practices in these facilities. We aimed to assess care practices, causes of admission, and outcomes from neonatal intensive care units (NICUs) in public secondary and private tertiary hospitals and both public and private medical colleges enrolled in a quality improvement collaborative in Telangana and Andhra Pradesh-2 Indian states with a respective population of 35 and 50 million.

METHODS AND FINDINGS

We conducted a cross-sectional study between 30 May and 26 August 2016 as part of a baseline evaluation in 52 consenting hospitals (26 public secondary hospitals, 5 public medical colleges, 15 private tertiary hospitals, and 6 private medical colleges) offering neonatal intensive care. We assessed the availability of staff and services, adherence to evidence-based practices at admission, and case fatality after admission to the NICU using a range of tools, including facility assessment, observations of admission, and abstraction of registers and telephone interviews after discharge. Our analysis is adjusted for clustering and weighted for caseload at the hospital level and presents findings stratified by type and ownership of hospitals. In total, the NICUs included just over 3,000 admissions per month. Staffing and infrastructure provision were largely according to government guidelines, except that only a mean of 1 but not the recommended 4 paediatricians were working in public secondary NICUs per 10 beds. On admission, all neonates admitted to private hospitals had auscultation (100%, 19 of 19 observations) but only 42% (95% confidence interval [CI] 25%-62%, p-value for difference is 0.361) in public secondary hospitals. The most common single cause of admission was preterm birth (25%) followed by jaundice (23%). Case-fatality rates at age 28 days after admission to a NICU were 4% (95% CI 2%-8%), 15% (9%-24%), 4% (2%-8%) and 2% (1%-5%) (Chi-squared p = 0.001) in public secondary hospitals, public medical colleges, private tertiary hospitals, and private medical colleges, respectively, according to facility registers. Case fatality according to postdischarge telephone interviews found rates of 12% (95% CI 7%-18%) for public secondary hospitals. Roughly 6% of admitted neonates were referred to another facility. Outcome data were missing for 27% and 8% of admissions to private tertiary hospitals and private medical colleges. Our study faced the limitation of missing data due to incomplete documentation. Further generalizability was limited due to the small sample size among private facilities.

CONCLUSIONS

Our findings suggest differences in quality of neonatal intensive care and 28-day survival between the different types of hospitals, although comparison of outcomes is complicated by differences in the case mix and referral practices between hospitals. Uniform reporting of outcomes and risk factors across the private and public sectors is required to assess the benefits for the population of mixed-care provision.

[For a Europe 2019-2024 on the side of fundamental human rights.]

. For a Europe 2019-2024 on the side of fundamental human rights. Environmental conditions and inequalities profoundly affect our health and health systems. Some reflections are proposed, made by groups "external" to health systems, for a reflection on the cultural, environmental and social connections of these issues, which should serve as a backdrop to both the health practices and research.

The evolution of income-related inequalities in healthcare utilisation in Indonesia, 1993-2014

Objective

While the major policy changes in the Indonesian healthcare system over the last 25 years have been well documented, less is known about the accompanying changes in inequalities in healthcare utilisation during this period. Our study aimed to describe the trends in income-related inequalities in healthcare utilisation in Indonesia during the period 1993–2014.

Methods

A repeated cross-sectional study was conducted using data from the Indonesian Family Life Surveys from 1993, 2000, 2007, and 2014. We measured outpatient and inpatient healthcare utilisation in public and private provider as well as the overall utilisation. Standardised prevalence rate and relative index of inequality (RII) were used to measure the extent of inequalities in healthcare utilisation by income level (income-related inequalities).

Results

Relatively large income-related inequalities were observed in the utilisation of private outpatient care and public and private inpatient care in 1993. Income-related inequalities in public and private outpatient care utilisation decreased between 1993 and 2007 but increased in 2014. Income-related inequalities in public and private inpatient care utilisation continued to decrease between 1993 and 2014. The largest decrease was observed in private inpatient care utilisation.

Conclusion

Income-related inequalities in all types of healthcare utilisation decreased until 2007. This trend continued until 2014 only for public and private inpatient care utilisation. This phenomenon may be explained by the changes to the healthcare system (e.g. expansion of the government health insurance programme and health sector decentralisation), which coincided with the changes in inequalities in healthcare utilisation in Indonesia.

Emerging Concepts in Precision Medicine and Cardiovascular Diseases in Racial and Ethnic Minority Populations

Cardiovascular diseases remain the leading cause of mortality and a major contributor to preventable deaths worldwide. The dominant modifiable risk factors and the social and environmental determinants that increase cardiovascular risk are known, and collectively, are as important in racial and ethnic minority populations as they are in majority populations. Their prevention and treatment remain the foundation for cardiovascular health promotion and disease prevention. Genetic and epigenetic factors are increasingly recognized as important contributors to cardiovascular risk and provide an opportunity for advancing precision cardiovascular medicine. In this review, we explore emerging concepts at the interface of precision medicine and cardiovascular disease in racial and ethnic minority populations. Important among these are the lack of racial and ethnic diversity in genomics studies and biorepositories; the resulting misclassification of benign variants as pathogenic in minorities; and the importance of ensuring ancestry-matched controls in variant interpretation. We address the relevance of epigenetics, pharmacogenomics, genetic testing and counseling, and their social and cultural implications. We also examine the potential impact of precision medicine on racial and ethnic disparities. The National Institutes of Health's All of Us Research Program and the National Heart, Lung, and Blood Institute's Trans-Omics for Precision Medicine Initiative are presented as examples of research programs at the forefront of precision medicine and diversity to explore research implications in minorities. We conclude with an overview of implementation research challenges in precision medicine and the ethical implications in minority populations. Successful implementation of precision medicine in cardiovascular disease in minority populations will benefit from strategies that directly address diversity and inclusion in genomics research and go beyond race and ethnicity to explore ancestry-matched controls, as well as geographic, cultural, social, and environmental determinants of health.

Neighborhood Differences in Alternative Tobacco Product Availability and Advertising in New York City: Implications for Health Disparities

INTRODUCTION

Alternative tobacco products (ATPs), such as cigars, smokeless tobacco, and electronic nicotine delivery systems (ENDS), have a strong presence in the US retail environment amid declining cigarette consumption. This study documented the promotion of ATPs in tobacco retailers in New York City and examined associations with neighborhood demographics.

METHODS

Data on product availability and advertising were collected from a stratified, random sample of tobacco retailers in 2017 (n = 796). Multilevel models estimated adjusted prevalence ratios (aPRs) for each outcome by neighborhood racial/ethnic composition and median household income.

RESULTS

Nearly half (49.8%) of retailers carried 99-cent cigarillos, but availability was significantly greater in neighborhoods in the highest (vs. lowest) quartile for the percentage of Black residents [68.2%, aPR: 1.59 (1.19, 2.11)] and in the lowest (vs. highest) income quartile [67.3%, aPR: 1.56 (1.04, 2.35)]. Conversely, retailers in neighborhoods with the highest percentage of White residents were significantly more likely to carry ENDS [66.4%, aPR: 1.71 (1.11, 2.62)]. Advertisements for ENDS were less common in neighborhoods in the highest (vs. lowest) quartiles for the percentage of Black and Hispanic residents [20.3%, aPR: 0.64 (0.41, 0.99); 22.9%, aPR: 0.62 (0.40, 0.98)].

CONCLUSIONS

The marketing of inexpensive, combusted tobacco products disproportionately saturates low-income, minority communities, while potentially lower risk, noncombusted products are more accessible in largely White and higher income neighborhoods. This pattern may exacerbate tobacco-related inequities. Public health policies should prioritize reducing the appeal and affordability of the most harmful tobacco products to help reduce health disparities.

IMPLICATIONS

Although cigarette promotion at the point-of-sale is well documented in the literature, questions remain about the ways in which alternative tobacco products (ATPs) are marketed in communities. Importantly, these products fall on a continuum of harm, with combusted tobacco overwhelmingly responsible for tobacco-related death and disease. We found that retailers in minority and low-income communities were more likely to carry and advertise inexpensive ATPs such as cigarillos, while potentially less risky, noncombusted products such as smokeless tobacco and e-cigarettes were more accessible in higher income and predominantly White neighborhoods. Policies aligned with product risk may help reduce health disparities.

Changes in inequality of childhood morbidity in Bangladesh 1993-2014: A decomposition analysis

INTRODUCTION

Child health remains an important public health concern at the global level, with preventable diseases such as diarrheal disease, acute respiratory infection (ARI) and fever posing a large public health burden in low- and middle-income countries including Bangladesh. Improvements in socio-economic conditions have tended to benefit advantaged groups in societies, which has resulted in widespread inequalities in health outcomes. This study examined how socioeconomic inequality is associated with childhood morbidity in Bangladesh, and identified the factors affecting three illnesses: diarrhea, ARI and fever.

MATERIALS AND METHODS

A total of 43,860 sample observations from the Bangladesh Demographic and Health Survey, spanning a 22-year period (1993-2014), were analysed. Concentration curve and concentration index methods were used to evaluate changes in the degree of household wealth-related inequalities and related trends in childhood morbidity. Regression-based decomposition analyses were used to attribute the inequality disparities to individual determinants for the three selected causes of childhood morbidity.

RESULTS

The overall magnitude of inequality in relation to childhood morbidity has been declining slowly over the 22-year period. The magnitude of socio-economic inequality as a cause of childhood morbidity varied during the period. Decomposition analyses attributed the inequalities to poor maternal education attainment, inadequate pre-delivery care, adverse chronic undernutrition status and low immunisation coverage.

CONCLUSIONS

High rates of childhood morbidity were observed, although these have declined over time. Socio-economic inequality is strongly associated with childhood morbidity. Socio-economically disadvantaged communities need to be assisted and interventions should emphasise improvements of, and easier access to, health care services. These will be key to improving the health status of children in Bangladesh and should reduce economic inequality through improved health over time.
