RESUMEN
OBJECTIVES: To develop an electronic descriptor of clinical deterioration for hospitalized patients that predicts short-term mortality and identifies patient deterioration earlier than current standard definitions. DESIGN: A retrospective study using exploratory record review, quantitative analysis, and regression analyses. SETTING: Twelve-hospital community-academic health system. PATIENTS: All adult patients with an acute hospital encounter between January 1, 2018, and December 31, 2022. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: Clinical trigger events were selected and used to create a revised electronic definition of deterioration, encompassing signals of respiratory failure, bleeding, and hypotension occurring in proximity to ICU transfer. Patients meeting the revised definition were 12.5 times more likely to die within 7 days (adjusted odds ratio 12.5; 95% CI, 8.9-17.4) and had a 95.3% longer length of stay (95% CI, 88.6-102.3%) compared with those who were transferred to the ICU or died regardless of meeting the revised definition. Among the 1812 patients who met the revised definition of deterioration before ICU transfer (52.4%), the median detection time was 157.0 min earlier (interquartile range 64.0-363.5 min). CONCLUSIONS: The revised definition of deterioration establishes an electronic descriptor of clinical deterioration that is strongly associated with short-term mortality and length of stay and identifies deterioration over 2.5 hours earlier than ICU transfer. Incorporating the revised definition of deterioration into the training and validation of early warning system algorithms may enhance their timeliness and clinical accuracy.

BACKGROUND: Respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and parainfluenza virus (PIV) hospitalize many people yearly. Though severe lower respiratory tract disease has been described in children, the elderly, and the immunocompromised, there is a gap in our understanding of RSV, hMPV, and PIV in hospitalized adults. We sought to evaluate the association of RSV, hMPV, and PIV with severe respiratory disease requiring noninvasive or mechanical ventilation and death in hospitalized adults in the United States. METHODS: We conducted a retrospective, pooled, cross-sectional study of general medicine hospitalizations in the United States from 2016 to 2019 using the National Inpatient Sample published by the Agency for Healthcare Quality and Research. We used multivariable Poisson regression to estimate the likelihood of severe respiratory disease or death. We used linear regression to estimate the mean difference in length of stay for those hospitalized with and without a respiratory virus. RESULTS: We found that RSV (incidence rate ratio [IRR]: 1.68, 95% confidence interval [CI]: 1.61-1.74, p < .001), hMPV (IRR: 1.82, 95% CI: 1.71-1.93, p < .001), and PIV (IRR: 1.81, 95% CI: 1.68-1.94, p < .001) were independently associated with severe respiratory disease, even after adjustment. Additionally, we found the presence of a respiratory virus prolonged hospitalizations by (0.79 ± 0.27 days, p < .003) for RSV, (0.88 ± 0.28 days, p < .002) for hMPV, and (1.43 ± 0.30 days, p < .001) for PIV. CONCLUSIONS: RSV, hMPV, and PIV have a significant burden on hospitalized adults, even without classic risk factors.

BACKGROUND: Malnutrition in hospitalized patients is associated increased length of stay, cost, readmission, and death. No recent studies have examined trends in prevalence or outcomes of hospitalized patients with a diagnosis of malnutrition. OBJECTIVES: To study the prevalence of malnutrition diagnostic codes and associated hospital outcomes in the United States between 2016 and 2019. METHODS: We conducted a retrospective trends study to identify use of malnutrition codes in hospitalizations in the National Inpatient Sample between 2016 and 2019. We used direct standardization by logistic regression to adjust outcomes of percutaneous gastrostomy tube placement, mechanical ventilation, and death for age, Gagne comorbidity score, and sex. We then used linear regression to test for trends over time by malnutrition type. RESULTS: Across all hospitalizations, codes for diagnoses of non-severe malnutrition and severe malnutrition were present in 3.7% and 4.1% of hospitalizations, respectively. Codes for any malnutrition increased over time, from 6.6% in 2016 to 8.6% in 2018 (p = .03). Codes for severe malnutrition increased from 3.3% to 4.7% (p = .01). Among hospitalizations with coded severe malnutrition diagnoses, there was a statistically significant decrease in adjusted rate of death over time (-0.54% per year, p = .03) which was not seen in hospitalizations without coded malnutrition diagnoses. CONCLUSIONS: Use of malnutrition diagnosis codes increased significantly from 2016 to 2019. During this time, mortality among hospitalizations with a diagnosis code for severe malnutrition decreased. Though the increased prevalence of malnutrition codes may represent a change in the clinical characteristics of hospitalized patients, the decline in mortality suggests some of the increase may be due to lower threshold for coding and assignment of the diagnosis to less ill patients.
RESUMEN
Background: COVID-19 is associated with hypercoagulability and increased incidence of thrombosis. We compared the clinical outcomes of adults hospitalized with COVID-19 who were on therapeutic anticoagulants to those on prophylactic anticoagulation. Materials and methods: We performed an observational study of adult inpatients' with COVID-19 from March 9 to June 26, 2020. We compared patients who were continued on their outpatient prescribed therapeutic anticoagulation and those who were newly started on therapeutic anticoagulation for COVID-19 (without other indication) to those who were on prophylactic doses. The primary outcome was overall death while secondary outcomes were critical illness (World Health Organization Ordinal Scale for Clinical Improvement score ≥5), mechanical ventilation, and death among patients who first had critical illness. We adjusted for age, sex, race, body mass index (BMI), Charlson score, glucose on admission, and use of antiplatelet agents. Results: Of 1716 inpatients with COVID-19, 171 patients were continued on their therapeutic anticoagulation and 78 were started on new therapeutic anticoagulation for COVID-19. In patients continued on home therapeutic anticoagulation, there were no differences in overall death, critical illness, mechanical ventilation, or death among patients with critical illness compared to patients on prophylactic anticoagulation. In patients receiving new therapeutic anticoagulation for COVID-19, there was increased death (OR 5.93; 95% CI 3.71-9.47), critical illness (OR 14.51; 95% CI 7.43-28.31), need mechanical ventilation (OR 11.22; 95% CI 6.67-18.86), and death after first having critical illness (OR 5.51; 95% CI 2.80-10.87). Conclusions: Therapeutic anticoagulation for inpatients with COVID-19 was not associated with improved outcomes.
