Estimating state-specific population-based hospitalization rates from in-state hospital discharge data.
The purpose of this study was to develop weights to estimate state population-based hospitalization rates for all residents of a state using only data from in-state hospitals. The researchers utilized Agency for Healthcare Research and Quality, Healthcare Cost and Utilization Project (HCUP), State Inpatient Databases (SID), for data from 2018-2019, including 47 states plus Washington D.C. and excluding residents treated in other states. SID were based on administrative billing records collected by hospitals, shared with statewide data organizations, and provided to HCUP. The study found that of 34,186,766 discharged patients in 2018, 4.2% were movers. A greater share of movers (vs. stayers) lived in state border and rural counties; a lower share had discharges billed to Medicaid or were hospitalized for maternal/neonatal services. The difference between 2019 observed and estimated total discharges for all included states and D.C. was 9,402. The researchers reported an overestimation of discharges with an expected payer of Medicaid, from the lowest income communities, and for maternal/neonatal care. The researchers reported an underestimation of discharges with an expected payer of private insurance, from the highest income communities, and with injury diagnoses and surgical services. Estimates for the majority of subsets were reported to be not within a 95% confidence interval, attributed to factors such as hospital closures/openings, shifting consumer preferences, and other issues impossible to account for.

Critical revisits among children after emergency department discharge.
This retrospective study’s objectives were to determine the rate of critical emergency department (ED) revisits among children discharged from the ED and to identify factors associated with critical revisits. Using the HCUP State ED Databases (SEDD) and State Inpatient Databases (SID), researchers examined data from six states, including patients under 21 years old. The findings indicated that critical ED revisits after discharge were uncommon and patient death within three days of ED discharge were rare; patients with complex chronic conditions were more likely to have a critical ED revisit. The researchers concluded that future research should focus on understanding higher risk among patients with asthma or a history of complex chronic conditions.

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.

Assessment of hospital readmissions from the emergency department after implementation of Medicare's hospital readmissions reduction program.
The purpose of this study was to examine whether the Medicare Hospital Readmissions Reduction Program (HRRP) was associated with changes in the probability of readmission at emergency department (ED) visits after hospital discharge (ED revisits) overall and depending on whether admission is typically indicated for the patient's condition at the ED revisit. Using hospital and ED discharge data from California, Florida, and New York, findings suggested that implementation of the HRRP was associated with a lower likelihood of readmission for recently discharged patients presenting to the ED, specifically for congestive heart failure. These findings highlighted the critical role of the ED in readmission reduction under the HRRP and suggested that patient outcomes after HRRP implementation merit further study.

Association between severe maternal morbidity and psychiatric illness within 1 year of hospital discharge after delivery.
The purpose of this study was to estimate whether severe maternal morbidity is associated with increased risk of psychiatric illness in the year after delivery hospital discharge. Results showed that although absolute numbers were modest, severe maternal morbidity was associated with increased risk of severe postpartum psychiatric morbidity and substance use disorder. The highest period of risk extended to 4 months after hospital discharge.

Medicare Advantage and traditional Medicare hospitalization intensity and readmissions.
This study uses 2013 Healthcare Cost and Utilization Project hospital discharge data from 22 states to compare hospital cost, length of stay, and readmissions for Traditional Medicare and Medicare Advantage. The authors found that Medicare Advantage hospitalizations were substantially less expensive and shorter for mental health stays but costlier and longer for injury and surgical stays.

Mental health conditions and unplanned hospital readmissions in children.
Mental health conditions (MHCs) are prevalent among hospitalized children and could influence the success of hospital discharge. The objective of this retrospective cross-sectional study was to assess the relationship between MHCs and 30-day readmissions. The investigators concluded that MHCs were associated with a higher likelihood of hospital readmission in children admitted for medical conditions and procedures. They suggest that understanding the influence of MHCs on readmissions could guide strategic planning to reduce unplanned readmissions for children with co-occurring physical and mental health conditions.

Hospital length of stay and readmission: an early investigation.
This study is a retrospective examination of the association between length of stay in an index hospitalization and readmission within 7 days and within 30 days of discharge. It found negative associations between length of stay and readmission probability, particularly for heart attack patients; however, the magnitude of the effect was modest for heart attack.

Variation in prevalence of gestational diabetes mellitus among hospital discharges for obstetric delivery across 23 states in the United States.
The authors examined variability in diagnosed gestational diabetes mellitus (GDM) prevalence at delivery by race/ethnicity and state. Their results suggest that GDM rates differ by state, with this variation attributable to differences in obesity at the population level, age, race/ethnicity, hospital, and insurance.
