Association of neighborhood opportunity and pediatric hospitalization rates in the United States.
This study examined associations between a validated, multidimensional measure of social determinants of health and population-based hospitalization rates among children <18 years across 18 states from the 2017 Healthcare Cost and Utilization Project State Inpatient Databases and the US Census. Exposure was ZIP code-level Child Opportunity Index (COI), a composite measure of neighborhood resources and conditions that matter for children's health. The cohort included 614,823 hospitalizations among a population of 29,244,065 children, which measures at 21.02 hospitalizations per 1000. Adjusted hospitalization rates decreased significantly and in a stepwise fashion as COI increased, from 26.56 per 1000 in very low COI areas to 14.76 per 1000 in very high COI areas (incidence rate ratio 1.8). Decreasing neighborhood opportunity was associated with increasing hospitalization rates among children in the study.

Association of hospital discharge against medical advice and coded housing instability in the US.
This study examined the relationship between discharge type and housing instability, then identified primary reasons for hospitalization among self-discharged patients with housing instability. This cross-sectional, retrospective study analyzed the National Inpatient Sample between January 2017 and December 2019, available from the Agency for Healthcare Research and Quality’s Healthcare Cost and Utilization Project. Among 85,402,831 hospitalizations analyzed, 1.6% resulted in self-discharge. Compared to admissions with planned discharges, self-discharges were more likely to have coded housing instability. Among hospitalizations resulting in self-discharge, admissions with coded housing instability were more likely to result in self-discharge than those without coded housing instability. Relationships between housing instability and self-discharges were found among major medical conditions: septicemia, acute myocardial infarction, and respiratory failure. Alcohol-related disorders and opioid-related disorders were among the highest self-discharge volumes, but relationships were minimal.

Hospital location and socioeconomic disadvantage of emergency general surgery patients.
This study’s purpose was to test the hypothesis that a hospital’s neighborhood disadvantage is associated with vulnerability of its emergency general surgery (EGS) patients. An area deprivation index (ADI), which is a neighborhood-level measure of disadvantage, and key characteristics of 724 hospitals in 14 states were linked to patient-level data in State Inpatient Databases. Hospitals in more disadvantaged areas disproportionately serve underserved EGS patient populations but are less likely to have robust resources for EGS care or train future EGS surgeons.

Multilevel risk factors for hospital readmission among patients with opioid use disorder in selected US States: role of socioeconomic characteristics of patients and their community.
This study examined the association of socioeconomic characteristics of individuals hospitalized with a principal diagnosis of opioid use disorder and their all-cause 30-day readmission risks. Discharge data from the 2014 HCUP Survey was used and was linked to community and hospital characteristics using data from HRSA and the American Hospital Association. Medicare is associated with the highest readmission risk followed by Medicaid covered patients. Self-pay or covered by other payers had a similar risk to private insurance coverage. Urban patients also had a higher readmission rate than rural patients.

Associations between social risk factors and surgical site infections after colectomy and abdominal hysterectomy.
The purpose of this study was to determine whether social risk factors, including race/ethnicity, insurance status, and neighborhood income, were associated with higher rates of surgical site infections (SSI) after colectomy or abdominal hysterectomy, 2 surgical procedures for which SSI rates are publicly reported and included in pay-for-performance programs by Medicare and other groups. The investigators report that inconsistent associations between social risk factors and SSIs were found.

Adults with diabetes residing in "food swamps" have higher hospitalization rates.
This study examined the relationship between ‘food swamps’ and hospitalization rates among adults with diabetes. Food Swamps are defined and measured by a ratio of fast food outlets to grocery stores within a given area. Data resources for this study included the Blue Cross Blue Shield Association Community Health Management Hub(R), AHRQ’s Health Care Cost and Utilization Project State Inpatient Databases, and HHS’s Area Health Resources File. The study concludes that higher hospitalization rates among adults with diabetes are significantly associated with food swamps, more so in rural than urban communities, and that improvements to local food environments may help to reduce this disparity.

Geography, not health system affiliations, determines patients' revisits to the emergency department.
This study sought to determine how frequently patients revisit the emergency department after an initial encounter, and to describe revisit capture rates for the same hospital, health system, and geographic region. Seventy percent of 30-day returns occurred to the same hospital. The 30-day return capture rates were highest within the same geographic area: county-level capture at 92 percent versus health system capture at 75 percent.

Intimate partner violence-related hospitalizations in Appalachia and the non-Appalachian United States.
The objective of this study was to estimate the rate of intimate partner violence -related hospitalizations in Appalachia and the non-Appalachian United States for 2007-2011 and compare hospitalizations in each region by clinical and sociodemographic factors.. After adjusting for age and rurality, Appalachian counties had a 22 percent higher hospitalization rate than non-Appalachian counties.

Trends in 30-day readmission rates after COPD hospitalization, 2006-2012.
This study investigated trends in 30-day readmission rates after chronic obstructive pulmonary disease (COPD)-related hospitalization. Overall, the 30-day readmission rate for COPD-related hospitalization decreased modestly from 20.0 percent in 2006 to 19.2 percent in 2012. Similar to the overall population, the readmission rate over the 7-year period remained persistently high in most of AHRQ-defined priority populations.

Impact of race/ethnicity and socioeconomic status on risk-adjusted hospital readmission rates following hip and knee arthroplasty.
This study examined the extent to which risk-adjusting for race/ethnicity and socioeconomic status affected hospital performance in terms of readmission rates following total hip arthroplasty (THA) and total knee arthroplasty (TKA). It found that inclusion of race/ethnicity and socioeconomic status in the risk-adjustment algorithm led to a relative-performance change in readmission rates following THA and TKA at less than 3 percent of the hospitals.

Annual report on health care for children and youth in the United States: trends in racial/ethnic, income, and insurance disparities over time, 2002-2009.
Using MEPS and HCUP data, the authors examined trends in children's health access, utilization, and expenditures over time by race/ethnicity, income, and insurance status/expected payer. They found that disparities by race/ethnicity and income persist in access to and use of care, with Hispanic children experiencing progress in a number of measures, while black children did not.
