Delirium due to potentially avoidable hospitalizations among older adults.
This retrospective cross-sectional study examined delirium rates among 39,933 older adults hospitalized for ambulatory care-sensitive conditions (ACSCs) at a large Southeastern academic medical center from 2015 to 2019. Delirium occurred in 15.6% of admissions, with lower rates observed for ACSC admissions compared to non-ACSC admissions. Older age and higher comorbidity were significant predictors of delirium development. While delirium rates were lower for ACSC admissions, optimizing outpatient management of ACSCs remains crucial for reducing hospitalizations and associated complications like delirium.

Association between community social vulnerability and preventable hospitalizations.
The purpose of this study was to explore the relationship between variations in social vulnerability and preventable hospitalization rates. The researchers analyzed county-level preventable hospitalization rates for 33 states linked with data from the 2020 Social Vulnerability Index (SVI). The study found that preventable hospitalizations were 40% greater in the most vulnerable counties compared with the least vulnerable. Adjusted regression results confirm the strong relationship between social vulnerability and preventable hospitalizations.

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.

Home health agencies with high quality of patient care star ratings reduced short-term hospitalization rates and increased days independently at home.
Accurate Medicare Quality of Patient Care home health star ratings are crucial to helping patients find high-quality care, yet critics of these ratings indicate that they are not valid. The purpose of this retrospective study was to assess whether using the highest-rated home health agency available in a ZIP code improves outcomes. The researchers included 1,870,080 Medicare fee-for-service beneficiaries using home health care from July 2015 through July 2016 in the United States. The study found that treatment by the highest-rated agencies available decreased risks of hospitalization, emergency department use, and institutionalization during the initial episode, and increased days independently at home by 2.6% or 3.75 days in the 180 days after the end of the initial episode. Treatment effects were stronger for agencies that were above-average, had 1 or more stars than the next-best agency, and nonrural residents. Effects were positive for both postacute and community-entry patients.

Rates of medical errors and preventable adverse events among hospitalized children following implementation of a resident handoff bundle.
The researchers sought to determine whether introduction of a multifaceted handoff program was associated with reduced rates of medical errors and preventable adverse events, fewer omissions of key data in written handoffs, improved verbal handoffs, and changes in resident-physician workflow. They found that implementation of a handoff bundle was associated with a significant reduction in medical errors and preventable adverse events among hospitalized children.

Ethnic differences in potentially preventable hospitalizations among Asian Americans, Native Hawaiians, and other Pacific Islanders: implications for reducing health care disparities.
This study aimed to produce reliable estimates of health care quality among Native Hawaiian (NH), Other Pacific Islander (PI), and Asian American (AA) small population subgroups. Results showed that, despite efforts to reduce racial/ethnic health care disparities, significant gaps remain in potentially preventable hospitalization rates.

Inpatient rehabilitation centers and concern for increasing volume of ischemic stroke patients requiring rehabilitation.
The researchers aimed to quantify the proportion of medically stable ischemic stroke patients with prolonged length of stay (pLOS) caused by a lack of IRF bed availability. They concluded that for the majority of our patients, pLOS was caused by acquired medical complications and delayed disposition, most commonly inpatient rehabilitation.

Predictors of medical or surgical and psychiatric hospitalizations among a population-based cohort of homeless adults.
This study identified factors associated with inpatient hospitalizations among a population-based cohort of homeless adults in Toronto, Ontario. Health care need was a strong predictor of medical or surgical and psychiatric hospitalizations. Some hospitalizations among homeless adults were potentially avoidable, whereas others represented an unavoidable use of health services.

Estimating inpatient hospital prices from state administrative data and hospital financial reports.
The researchers developed a tool for estimating hospital-specific inpatient prices for major payers. They found that hospital prices can be reasonably estimated for 10 geographically diverse states. They further found that estimated prices compare well with Medicare, MarketScan private insurance, and the Medical Expenditure Panel Survey prices for major payers, given limitations of each dataset.

Standardizing Medicare payment information to support examining geographic variation in costs.
This paper describes a method for standardizing claim payments, and demonstrates the difference in actual versus standardized payments by geographic region. It found that without standardization of payments, certain areas of the country are mischaracterized as either high or low healthcare resource-consuming areas.

Potentially avoidable hospitalizations for elderly long-stay residents in nursing homes.
The authors sought to determine the relationship between clinical risk factors, facility characteristics and State policy variables, and both avoidable and unavoidable hospitalizations. Using data from the Nursing Home Stay file, 2006-2008, they found that three fifths of hospitalizations were potentially avoidable and most were for infections, injuries, and congestive heart failure. Clinical risk factors included renal disease, diabetes, and a high number of medications. Staffing, quality, and reimbursement affected avoidable, but not unavoidable, hospitalizations.

Hospital utilization, costs, and mortality for adults with multiple chronic conditions, Nationwide Inpatient Sample, 2009.
The investigators provided a national estimate across all payers of the distribution and cost of selected chronic conditions for hospitalized adults in 2009, stratified by demographic characteristics. They found that there were approximately 28 million adult discharges from US hospitals other than those related to pregnancy and maternity; 39% had 2 to 3 multiple chronic conditions (MCC), and 33% had 4 or more. They concluded that their descriptive analysis of multipayer inpatient data provides a robust national view of the substantial use and costs among adults hospitalized with MCC.

Microsimulation of financial impact of demand surge on hospitals: the H1N1 influenza pandemic of fall 2009.
Microsimulation was used to assess the financial impact on hospitals of a surge in influenza admissions in advance of the H1N1 pandemic in the fall of 2009 with the goal of estimating net income and losses of a response of filling unused hospital bed capacity proportionately and postponing elective admissions. They concluded that aggregate and distributional results did not suggest that a policy of promising additional financial compensation to hospitals in anticipation of the surge in flu cases was necessary.

Variation in emergency department admission rates across the United States.
The authors investigated factors related to variation in hospital-level emergency department (ED) admission rates. Using HCUP data, they found that higher proportions of Medicare and uninsured patients, more inpatient beds, lower ED volumes, for-profit ownership, trauma center status, and higher hospital occupancy rates were associated with higher ED admission rates.
