BACKGROUND: Chronic systemic anticoagulation use is prevalent for various thromboembolic conditions. Anticoagulation (usually through heparin products) is also recommended for the initial management of non-ST-elevation myocardial infarction (NSTEMI).
OBJECTIVE: To evaluate the in-hospital outcomes of patients with NSTEMI who have been on chronic anticoagulation.
METHODS: Using the National Inpatient Sample (NIS) years 2016-2020, NSTEMI patients and patients with chronic anticoagulation were identified using the appropriate International Classification of Diseases, 10th version (ICD-10) appropriate codes. The primary outcome was all-cause in-hospital mortality while the secondary outcomes included major bleeding, ischemic cerebrovascular accident (CVA), early percutaneous coronary intervention (PCI) (i.e., within 24 h of admission), coronary artery bypass graft (CABG) during hospitalization, length of stay (LOS), and total charges. Multivariate logistic or linear regression analyses were performed after adjusting for patient-level and hospital-level factors.
RESULTS: Among 2,251,914 adult patients with NSTEMI, 190,540 (8.5%) were on chronic anticoagulation. Chronic anticoagulation use was associated with a lower incidence of in-hospital mortality (adjusted odds ratio [aOR]: 0.69, 95% confidence interval [CI]: 0.65-0.73, p < 0.001). There was no significant difference in major bleeding (aOR: 0.95, 95% CI: 0.88-1.0, p = 0.15) or ischemic CVA (aOR: 0.23, 95% CI: 0.03-1.69, p = 0.15). Chronic anticoagulation use was associated with a lower incidence of early PCI (aOR: 0.78, 95% CI: 0.76-0.80, p < 0.001) and CABG (aOR: 0.43, 95% CI: 0.41-0.45, p < 0.001). Chronic anticoagulation was also associated with decreased LOS and total charges (adjusted mean difference [aMD]: -0.8 days, 95% CI: -0.86 to -0.75, p < 0.001) and (aMD: $-19,340, 95% CI: -20,692 to -17,988, p < 0.001).
CONCLUSIONS: Among patients admitted with NSTEMI, chronic anticoagulation use was associated with lower in-hospital mortality, LOS, and total charges, with no difference in the incidence of major bleeding.

BACKGROUND: Pneumonia places a significant burden on individuals and society, contributing to a substantial number of hospital admissions, emergency department visits, deaths, and healthcare costs each year. Comorbidities can greatly increase the risk of poor outcomes when associated with pneumonia. One comorbidity that has yet to be thoroughly researched is thrombocytopenia, which is known to play an important role in activating the immune response to infections. A decrease in platelet count may limit the immune response and consequently increase mortality in patients with pneumonia. The purpose of this study was to investigate whether comorbid thrombocytopenia and pneumonia are associated with poor outcomes.
METHODS: This study was a retrospective cohort analysis comparing mortality rates among patients with comorbid thrombocytopenia and pneumonia, pneumonia without thrombocytopenia, and thrombocytopenia without pneumonia. Data were collected from Freeman Health System using International Classification of Diseases, Tenth Revision (ICD-10) codes from January 1, 2019, to December 31, 2021. ICD-10 codes for pneumonia and thrombocytopenia were extracted and stratified into three groups: those with both pneumonia and thrombocytopenia, those with pneumonia without thrombocytopenia, and those with thrombocytopenia without pneumonia. Mortality rates were then compared across the three groups.
RESULTS: There were 4,414 patients admitted with pneumonia and 1,157 admissions for thrombocytopenia without pneumonia. Among the 4,414 patients admitted with pneumonia, 3,902 did not have thrombocytopenia, while 512 had thrombocytopenia. Of the patients without thrombocytopenia, 14% (3,902) expired. Among the 512 patients with thrombocytopenia, 43% expired. In the thrombocytopenia without pneumonia group, 11% (1,157) expired.
CONCLUSIONS: These results indicate a significant increase in mortality in patients with both pneumonia and thrombocytopenia compared to those with pneumonia without thrombocytopenia (an increase in mortality of 28.93% with a 95% CI: 24.50-33.36%, P < 0.0001). While pneumonia itself increases mortality compared to the general population, patients with both pneumonia and thrombocytopenia exhibit even higher mortality rates.

UNASSIGNED: This study examined inpatient mortality factors in geriatric patients with acute myeloid leukemia (AML) using data from the 2016 to 2020 National Inpatient Sample.
UNASSIGNED: Identifying patients through ICD-10 codes, a total of 127,985 individuals with AML were classified into age categories as follows: 50.58% were 65 to 74 years, 37.74% were 75 to 84 years, and 11.68% were 85 years or older. Statistical analysis, conducted with STATA, involved Fisher\'s exact and Student\'s t tests for variable comparisons. Mortality predictors were identified through multivariate logistic regression.
UNASSIGNED: Various hospital and patient-level factors, including an increase in age, race, a higher Charlson Comorbidity Index score, insurance status, and specific comorbidities such as atrial fibrillation and protein-calorie malnutrition, independently elevated the risk of inpatient mortality. Asthma, hyperlipidemia, and inpatient chemotherapy were linked to lower mortality. Although there was no statistically significant mortality rate change from 2016 to 2020, a decline in chemotherapy use in the eldest age group was noted.
UNASSIGNED: This study highlights the complexity of factors influencing inpatient mortality among geriatric patients with AML, emphasizing the need for personalized clinical approaches in this vulnerable population.

UNASSIGNED: Cachexia is a metabolic syndrome defined by a loss of more than 5% of body weight in patients with chronic diseases. The goal of this study was to investigate the link between cirrhotic cachexia and hospital mortality and the 30-day risk of all-cause readmission.
UNASSIGNED: The study utilized Nationwide Readmission Database for the years 2016-2019 in which all patients older than 18 year old with a primary diagnosis of cirrhosis were included. We excluded patients with a concurrent diagnosis of Human Immunodeficiency Virus, chronic lung disease, end-stage renal disease, malignancy, heart failure, and certain neurological diseases. We compared baseline characteristics and outcomes between those who were cachectic and those who were not. Survey multivariate logistic regression was used to analyze the independent impact of cachexia on categorical outcomes.
UNASSIGNED: The study cohort was 342,030 cases. Cachexia was identified in approximately 17% of the study population (58,509 discharges). The mean age was 56 years. Slightly more female patients noted in cachexia group (41% vs 38%). Inpatient mortality during index hospitalization were higher in patients with cirrhotic cachexia (6.7% vs 3%, P < .01). Inpatient mortality during first all-cause readmission within 30 days of index discharge was also higher in cachexia group (8.6% vs 6.5%, P < .01).
UNASSIGNED: Cachexia is an adverse prognosticator for inpatient outcomes in patients with cirrhosis. It is associated with greater readmission rates, inpatient mortality, and prolonged hospital admissions.

Background: This study investigated the impact of COVID-19 on patients with sickle cell crisis (SCC) using National Inpatient Sample (NIS) data for the year 2020. Methods: A retrospective cohort analysis was conducted utilizing International Classification of Diseases (ICD-10) codes to identify adults who were admitted with a principal diagnosis of sickle cell crisis. The primary outcomes examined were inpatient mortality, while the secondary outcomes assessed included morbidity, hospital length of stay, and resource utilization. Analyses were conducted with STATA. Multivariate logistic and linear regression analyses were used to adjust for confounding variables. Results: Of 66,415 adult patients with a primary SCC diagnosis, 875 were identified with a secondary diagnosis of COVID-19 infection. Unadjusted mortality rate was higher for SCC patients with COVID-19 (2.28%) compared to those without (0.33%), with an adjusted odds ratio (aOR) of 8.49 (p = 0.001). They also showed increased odds of developing acute respiratory failure (aOR = 2.37, p = 0.003) and acute kidney injury requiring dialysis (aOR = 8.66, p = 0.034). Additionally, these patients had longer hospital stays by an adjusted mean of 3.30 days (p < 0.001) and incurred higher hospitalization charges by an adjusted mean of USD 35,578 (p = 0.005). Conclusions: The SCC patients with COVID-19 presented higher mortality rates, increased morbidity indicators, longer hospital stays, and substantial economic burdens.

BACKGROUND: The \"obesity paradox\" claims that although obesity is a risk factor for atrial fibrillation, obese patients have lower inpatient mortality when admitted due to atrial fibrillation. This study aims to analyze if the obesity paradox still holds true after weight loss from bariatric surgery.  Methods: This study analyzed discharge data from the National Inpatient Sample, 2016-2020. Patients admitted due to atrial fibrillation or atrial flutter, with or without obesity, and with or without a past medical history of bariatric surgery were identified using ICD-10-CM and ICD-10-PCS codes. The primary outcome was mortality. Secondary outcomes included length of stay, resource utilization, necessity for endotracheal intubation, and necessity for cardioversion. STATA v.13 was used for univariate and multivariate analysis (StataCorp LLC, Texas, USA).
RESULTS: Among 2,292,194 patients who had a primary diagnosis of atrial fibrillation or atrial flutter, 494,830 were obese and 25,940 had bariatric surgery. Mortality was not significantly different in post-bariatric surgery patients when compared to the general population (OR 0.76; 95% [CI 0.482-1.2; p=0.24]). Mortality was significantly lower in obese patients when compared to the general population (OR 0.646; 95% [CI 0.583-0.717; p<0.001]). Therefore, post-bariatric surgery patients had a higher mortality than obese patients when compared to the general population. Obese patients spent more days in the hospital (regression 0.219; 95% [CI 0.19-0.248, p<0.001]), had higher resource utilization (regression 3491.995; 95% [CI 2870.085-4113.905, p<0.001]), more cardioversions (OR 1.434; 95% [CI 1.404-1.465; p<0.001]), and no difference in endotracheal intubation rate (OR 1.02; 95% [CI 0.92-1.127; p=0.724]) when compared to the general population. Post-bariatric patients had no difference in length of stay (regression -0.053; 95% [CI -0.137-0.031; p=0.218]) and resource utilization (regression 577.297; 95% [CI -1069.801-2224.396; p=0.492]), fewer endotracheal intubations (OR 0.583; 95% [CI 0.343-0.99; p=0.046]), and more cardioversions (OR 1.223; 95% [CI 1.134-1.32; p<0.001]) when compared to the general population.
CONCLUSIONS: Compared to the general population, post-bariatric patients had higher inpatient mortality than obese patients when admitted due to atrial fibrillation or atrial flutter. This research reinforces the presence of the obesity paradox following bariatric surgery with respect to mortality.

UNASSIGNED: Variceal and nonvariceal upper gastrointestinal bleeding (VUGIB and NVUGIB, respectively) require prompt intervention. Existing studies offer limited insight into the impact of interhospital transfers on patients with VUGIB and NVUGIB.
UNASSIGNED: We conducted a retrospective study using the US National Inpatient Sample database from 2017 to 2020. The outcomes included in-hospital mortality, incidence of complications, procedural performance, and resource utilization.
UNASSIGNED: A total of 28,275 VUGIB and 781,370 NVUGIB adult patients were included. Transferred VUGIB and NVUGIB patients, when compared to nontransferred ones, demonstrated higher inpatient mortality (adjusted odds ratio [AOR] 1.49 and 1.86, P < 0.05). Patients with VUGIB and NVUGIB had a higher likelihood of acute kidney injury requiring dialysis (AOR 3.79 and 1.76, respectively, P = 0.01), vasopressor requirement (AOR 2.13 and 2.37, respectively, P < 0.01), need for mechanical ventilation (AOR 1.73 and 2.02, respectively, P < 0.01), and intensive care unit admission (AOR 1.76 and 2.01, respectively, P < 0.01). Compared to their nontransferred counterparts, transferred VUGIB patients had a higher rate of undergoing transjugular intrahepatic portosystemic shunt (AOR 3.26, 95% CI 1.92-5.54, P < 0.01), while transferred NVUGIB patients had a higher rate of interventional radiology-guided embolization (AOR 2.01, 95% CI 1.73-2.34, P < 0.01) and endoscopic hemostasis (AOR 1.10, 95% CI 1.05-1.15, P < 0.01).
UNASSIGNED: Interhospital transfer is associated with worse clinical outcomes and higher resource utilization for VUGIB and NVUGIB patients.

Spontaneous coronary artery dissection (SCAD) is a rare cause of ST-segment elevation myocardial infarction (STEMI), predominantly affecting women. Because primary percutaneous coronary intervention (PPCI) is reserved for a select group of patients, vulnerable and minority patients may experience delays in appropriate management and adverse outcomes. We examined the racial differences in the outcomes for patients with SCAD who underwent PPCI for STEMI. Records of patients aged ≥18 years who underwent PPCI for SCAD-related STEMI between 2016 and 2020 were identified from the National Inpatient Sample database. Clinical, socioeconomic, and hospital characteristics were compared between non-White and White patients. Weighted multivariate analysis assessed the association of race with inpatient mortality, length of stay (LOS), and hospitalization costs. The total weighted estimate of patients with SCAD-STEMI who underwent PPCI was 4,945, constituting 25% non-White patients. Non-White patients were younger (56 vs 60.7 years, p <0.001); had a higher prevalence of diabetes, acute renal failure, and obesity; and were more likely to be uninsured and be in the lowest income group. Inpatient mortality (7.7% vs 8.4%, p = 0.74) and hospitalization costs ($34,213 vs $31,858, p = 0.27) were similar for non-White and White patients, and the adjusted analysis did not show any association between the patients\' race and inpatient mortality (odds ratio 0.60, 95% confidence interval [CI] 0.32 to 1.13, p = 0.11) or hospitalization costs (β [β coefficient]: 215, 95% CI -4,193 to 4,623, p >0.90). Similarly, there was no association between the patients\' race and LOS (incident rate ratio 1.20, 95% CI 1.00 to 1.45, p = 0.054). The weighted multivariate analysis showed that age; clinical co-morbidities such as diabetes, acute renal failure, valvular dysfunction, and obesity; low-income status; and hospitalization in the western region were associated with adverse outcomes. In conclusion, our study does not show any differences in inpatient mortality, LOS, and hospitalization costs between non-White and White patients who underwent PPCI for SCAD-related STEMI.

The level of nurse-doctor interprofessional collaboration may influence patient outcomes, including mortality. To date, no systematic reviews have investigated the association between the quantity of nurse-doctor interprofessional collaboration and inpatient mortality. A systematic review was conducted. We included studies that measured the quantity of nurse-doctor interprofessional collaboration and in-patient mortality. Five databases (MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Register) were searched. Two researchers undertook the title, abstract, and full-text screening. The risk of bias was determined using the Effective Public Health Practice Project (EPHPP) critical appraisal tool. Six reports from three observational studies met the inclusion criteria. Participants included 1.32 million patients, 29,591 nurses, and 191 doctors. The included studies had a high risk of bias. Of the three studies, one reported a significant association and one found no association between the quantity of nurse-doctor collaboration and mortality. The third study reported on the quantity of nurse-doctor collaboration but did not report the test of this association. We found no high-quality evidence to suggest the amount of nurse-doctor interprofessional collaboration was associated with mortality in medical and surgical inpatients. There is a need for further high-quality research to evaluate the association between the amount of nurse-doctor collaboration and patient outcomes.

BACKGROUND: Pheochromocytoma is a rare cause of hypertensive emergency. The objective of this analysis was to compare the clinical characteristics, comorbidities, and in-hospital outcomes of patients admitted with hypertensive emergencies with and without co-existing pheochromocytoma.
METHODS: A retrospective analysis of the National Inpatient Sample (NIS) Database from 2016 to 2020 was conducted, encompassing 640,395 patients hospitalized for hypertensive emergencies, including 2535 patients diagnosed with pheochromocytoma. We compared demographics, comorbidities, in-hospital outcomes and resource utilization metrics in patients with and without pheochromocytoma. Propensity-score matching was utilized to account for potential confounders and risk of complications was compared.
RESULTS: Among the pheochromocytoma cohort (51.9% female), a significant portion (35.7%) were under 50 years of age, with the majority being Caucasian (47.9%). Comorbid conditions such as obesity, diabetes, and smoking were prevalent, with notable differences in cancer (7.5% vs. 2.3%, p < 0.001) and peripheral vascular disease (17% vs. 8.2%, p < 0.001) rates compared to the non-pheochromocytoma cohort. Pheochromocytoma patients had a longer hospital stay (7.5 vs. 6 days, p = 0.002) and higher odds of acute kidney injury (AKI) (1.54, 1.18-2, p=0.001) but lower odds of requiring hemodialysis (0.52, 0.32-0.79, p < 0.001) or experiencing major cardiovascular events (0.5, 0.36-0.69, p < 0.001). No significant difference in inflation-adjusted hospitalization costs was found between the groups.
CONCLUSIONS: Patients with hypertensive emergencies and pheochromocytoma had a higher incidence of AK, certain comorbidities (cancer, peripheral vascular disease), and more complex hospital courses suggested by longer length of stay. However, the overall cost of hospitalization did not significantly differ between the two cohorts.
