Neighborhood Deprivation and Crime on Asthma Exacerbations and Utilization in Mild Adult Asthma.

BACKGROUND: Social determinants of health (SDOH) have a significant impact on asthma outcomes, with factors such as income level and neighborhood environment playing crucial roles. OBJECTIVE: This study aimed to assess the impact of Neighborhood Deprivation Index (NDI) and Total Crime Index (TCI) on acute asthma exacerbation (AAE) and asthma-related Emergency Department and urgent care (ED/UC) visits in adults with mild asthma. METHODS: This retrospective cohort study utilized administrative data from Kaiser Permanente Southern California among 198,873 mild adult asthma patients between January 1, 2013, and December 31, 2018. Robust Poisson regression models, adjusted for age and sex, were employed to investigate the associations of NDI and TCI with AAE and asthma-related ED/UC visits. Data analysis included subgroup assessments by race and ethnicity and BMI categories to explore potential disparities in asthma outcomes. RESULTS: Among the cohort, 12,906 patients (6.5%) experienced AAE in one year, with Black patients having the highest AAE percentage (7.1%). Higher NDI quintiles were associated with increased AAE risk (aRRs: 1.11-1.27), with similar trends across BMI categories and race or ethnicity, except for Black patients. TCI showed weaker associations with AAE. Regarding ED/UC visits, 5.0% had such visits within one year. Higher NDI quintiles were associated with higher ED/UC visit risk (aRRs: 1.23-1.75), while TCI associations were weaker. CONCLUSION: Addressing socioeconomic disparities, as indicated by NDI, may be crucial in mitigating asthma exacerbations and reducing healthcare utilization, highlighting the importance of incorporating social determinants into asthma management strategies even in patients with mild asthma.

Distinct effects of racial and socioeconomic disparities on biliary atresia diagnosis and outcome.

OBJECTIVES: To identify and distinguish between racial and socioeconomic disparities in age at hepatology care, diagnosis, access to surgical therapy, and liver transplant-free survival in patients with biliary atresia (BA). METHODS: Single-center retrospective cohort study of 69 BA patients from 2010 to 2021. Patients were grouped into White and non-White cohorts. The socioeconomic milieu was analyzed utilizing neighborhood deprivation index, a census tract-based calculation of six socioeconomic variables. The primary outcomes of this study were timing of the first hepatology encounter, surgical treatment with hepatic portoenterostomy (HPE), and survival with native liver (SNL) at 2 years. RESULTS: Patients were 55% male and 72% White. White patients were referred at a median of 34 days (interquartile range [IQR]: 17-65) vs. 67 days (IQR: 42-133; p = 0.001) in non-White patients. White infants were more likely to undergo HPE (42/50 patients; 84%) compared to non-White (10/19; 53%), odds ratio (OR) 4.73 (95% confidence interval: 1.46-15.31; p = 0.01). Independent of race, patients exposed to increased neighborhood-level deprivation were less likely to receive HPE (OR: 0.49, p = 0.04) and achieve SNL (OR: 0.54, p = 0.02). CONCLUSIONS: Racial and socioeconomic disparities are independently associated with timely BA diagnosis, access to surgical treatment, and transplant-free survival. Public health approaches to improve screening for pathologic jaundice in infants of diverse racial backgrounds and to test and implement interventions for socioeconomically at-risk families are needed.

The Impact of Neighborhood Deprivation on the Survival Rates of Patients with Cancer in Korea.

The objective of this study is to investigate the correlation between the neighborhood deprivation index and survival rates of cancer patients in Korea. In this study, 5-year age-standardized survival rates of patients with cancer were determined using the National Cancer Cohort from 2014 to 2018 in Korea. The primary cancer sites were the stomach, colorectum, liver, lung, breast, cervix, prostate, and thyroid. Disparities were measured, and their impact on the overall survival rates was assessed using the Korean version of the Neighborhood Deprivation Index. Pearson's correlation coefficient was calculated to determine the strength of the correlation. The study cohort comprised 726,665 patients with cancer, of whom 50.7% were male. The predominant primary cancer sites were the stomach (n = 138,462), colorectum (n = 125,156), and thyroid gland (n = 120,886). Urban residents showed better survival outcomes than those situated in rural areas. The most deprived quartile had the lowest survival rate, while the least deprived quartile had the highest (p < 0.001). Most cancer types revealed significant correlations between neighborhood deprivation and 5-year age-standardized overall survival, with lung cancer showing the most substantial negative correlation (r = -0.510), followed by prostate cancer (r = -0.438). However, thyroid cancer showed only a marginal correlation (p = 0.069). The results of this study suggested that neighborhood deprivation is closely linked to disparities in overall survival across various types of cancer. A substantial negative correlation between the neighborhood deprivation index and all-cause mortality for lung and prostate cancer, as compared to breast and cervical cancers covered by the National Cancer Screening Program, may reinforce the need to address healthcare access and improve the early detection of cancer in socioeconomically deprived neighborhoods.
