Long short-term memory model identifies ARDS and in-hospital mortality in both non-COVID-19 and COVID-19 cohort.
The objective of this study was to identify risk of acute respiratory distress syndrome (ARDS) and in-hospital mortality using a long short-term memory (LSTM) framework in mechanically ventilated (MV) COVID-19 and non-COVID-19 cohorts. The results indicated that the LSTM algorithm accurately identified the risk of ARDS or death in both non-COVID-19 and COVID MV patients. The researchers concluded that a tool that alerts to the risk of ARDS or death can improve the implementation of evidence-based ARDS management and facilitate goals-of-care discussions involving high-risk patients.

Predicting healthcare-associated infections, length of stay, and mortality with the nursing intensity of care index.
The purpose of this study was to develop, validate, and utilize a simulation model to predict healthcare-associated infections (HAIs), length of stay (LOS), and patient mortality, as well as evaluate whether the variation in incidence of HAIs was dependent upon the adequacy of unit staffing levels. The researchers analyzed data from all patients discharged from four different types of New York City hospitals within a single healthcare network between 2012-2016 (N=562,435). The researchers developed a simulation model to estimate the daily probability rates of 5 different HAIs, length of stay, and mortality, and modeled staffing adequacy based on nursing care supply (as indicated by total nurse staffing) and nursing care demand (indicated using the Nursing Intensity of Care Index.) The study results indicated that the model predictions were within 95% confidence intervals of the actual outcomes. The authors reported that the incidence of HAI was the highest when total nurse staffing (supply) was lowest and nursing care intensity (demand) was highest.

Inpatient hospital performance is associated with post-discharge sepsis mortality.
The objective of this study was to test the hypothesis that hospitals with high risk-adjusted inpatient sepsis mortality also have high post-discharge mortality, readmissions, and discharge to nursing homes. Sepsis hospitalization survivors among age-qualifying Medicare beneficiaries were followed for 180 days post-discharge; mortality, readmissions, and new admission to skilled nursing facilities were measured. Findings showed that hospitals with the highest risk-adjusted sepsis inpatient mortality also had higher post-discharge mortality and increased readmissions, suggesting that post-discharge complications were a modifiable risk that may be affected during inpatient care. Recommendations for future work include seeking to elucidate inpatient and healthcare practices that can reduce sepsis post-discharge complications.

Hospital mortality and functional outcomes in pediatric neurocritical care.
Pediatric neurocritical care (PNCC) outcomes research is scarce. In this study, the investigators aimed to expand knowledge about outcomes in PNCC by evaluating death and changes in Functional Status Scale (FSS) from baseline among PNCC diagnoses. The investigators concluded that PNCC patients had high rates of death and new disability at discharge, varying significantly between PNCC diagnoses. Multiple domains of disability were affected, underscoring the ongoing multidisciplinary health care needs of survivors.

Prevalence, underlying causes, and preventability of sepsis-associated mortality in US acute care hospitals.
The purpose of this study was to estimate the prevalence, underlying causes, and preventability of sepsis-associated mortality in acute care hospitals. A retrospective medical record review was conducted of 568 randomly selected adults admitted to six US academic and community hospitals who died in the hospital or were discharged to hospice and not readmitted. Medical records were reviewed. Sepsis was found to be the most common immediate cause of death; however, most underlying causes were related to severe chronic comorbidities. Most sepsis-associated deaths were unlikely to be preventable through better hospital-based care. The authors conclude that further innovations in the prevention and care of underlying conditions may be necessary before a significant reduction in sepsis-associated deaths can be achieved.

Variation in and hospital characteristics associated with the value of care for Medicare beneficiaries with acute myocardial infarction, heart failure, and pneumonia.
The objectives of this study were to investigate the association between hospital-level 30-day risk-standardized mortality rates (RSMRs) and 30-day risk-standardized payments (RSPs) for acute myocardial infarction (AMI), heart failure (HF), and pneumonia (PNA); to characterize patterns of value in care; and to identify hospital characteristics associated with high-value care (defined by having lower than median RSMRs and RSPs).

Relationship between hospital 30-day mortality rates for heart failure and patterns of early inpatient comfort care.
This study describes the use of early comfort care for patients with heart failure (HF), and whether hospitals that more commonly initiate comfort care have higher 30-day mortality rates. It found that hospital use of early comfort care for HF varies, has not increased over time, and on average, is not correlated with 30-day risk-standardized mortality rates.

Association of hospitalist years of experience with mortality in the hospitalized Medicare population.
The purpose of the study is to describe the association of hospitalist years of experience with 30-day mortality and hospital mortality of their patients. The authors noted that patients cared for by hospitalists in their first year of practice experienced higher mortality. The authors asserted that early-career hospitalists may require additional support to ensure optimal outcomes for their patients.

Managed care and inpatient mortality in adults: effect of primary payer.
This study provides a comprehensive assessment of the association between managed care and inpatient mortality for Medicare and privately insured patients. Privately insured patients in managed care plans, especially older adults, had better outcomes than those in fee-for-service (FFS) plans. Patients in Medicare managed care had outcomes similar to those in Medicare FFS.

Risk-adjusted in-hospital mortality models for congestive heart failure and acute myocardial infarction: Value of clinical laboratory data and race/ethnicity.
This study examined the impact of key laboratory and race/ethnicity data on the prediction of in-hospital mortality for congestive heart failure (CHF) and acute myocardial infarction (AMI). It found that adding a simple three-level summary measure based on the number of abnormal laboratory data observed to hospital administrative claims data significantly improved the model prediction for inpatient mortality.
