BACKGROUND: Takotsubo cardiomyopathy (TC) is a commonly observed complication among patients with intracerebral hemorrhage (ICH); however, the incidence of TC in patients with ICH have not been investigated yet. The goal of this study was to examine the incidence of TC in ICH and identify its risk factors, incidence rate, and outcomes of TC in patients with ICH in a US nationwide scale. METHODS: Data for patients with ICH between the years of 2015 and 2018 were extracted from the Nationwide Inpatient Sample and stratified based on the diagnosis of TC. RESULTS: Our results showed that the incidence rate of TC in ICH discharges was 0.27% (95% confidence interval [CI] 0.24-0.31). The mean age of patients with ICH developing TC was 66.28 years ± 17.11. There were significantly more women in the TC group, with an odds ratio (OR) of 3.65 (95% CI 2.63-5.05). Acute myocardial infarction (OR 7.91, 95% CI 5.80-10.80) was significantly higher in the TC group. The mortality rate of patients with ICH who had TC was significantly higher (33.48%, p < 0.0001). Length of stay (mean days; 15.72 ± 13.56 vs. 9.56 ± 14.10, p < 0.0001) significantly increased in patients with ICH who had TC. Patients with intraventricular ICH (OR 2.46, 95% CI 1.88-3.22) had the highest odds of TC. CONCLUSIONS: Takotsubo cardiomyopathy is associated with a higher mortality, longer hospitalization period, and more acute myocardial infarctions in patients with ICH. It is illustrated that intraventricular ICH is associated with higher odds of TC.

OBJECTIVE: Takotsubo cardiomyopathy (TC) is a stress-induced cardiomyopathy that can be precipitated by aneurysmal subarachnoid hemorrhage (aSAH). Several studies have shown patients who develop TC following aSAH have an increased risk of disability and mortality. The goal of this study is to examine the incidence of TC in aSAH, identify its risk factors, and analyze its impact on patient outcomes. METHODS: Data for patients with aSAH between the years of 2009 and 2018 were extracted from the Nationwide Inpatient Sample (NIS) and stratified based on the diagnosis of TC. Univariate analysis was used to assess the incidence of TC and covariates including patient demographics, aneurysmal treatment, in-hospital mortality rate, length of stay and costs. Multivariate logistic regression models analyzed the relationship between TC and these variables RESULTS: 80,915 aSAH patient-discharges were included in this study, 673 (0.83%) of which, developed TC. Females (OR 3.49, CI [2.82-4.33], P < 0.001), white ethnicity (69% vs 63%, P = 0.003) and patients with certain comorbidities including smoking (OR 1.64, CI [1.38-1.95], P < 0.0001) and seizures (OR 1.32, CI [1.07, 1.64], P = 0.01) were most likely to develop TC. Patients who developed TC had significantly increased mortality (OR 1.36, CI [1.13-1.65], P = 0.001), hospital stays (mean days of 19.4 vs 11.5, P < 0.0001), and costs ($104,111 vs $48,734, P < 0.0001). Hypertension (OR 0.63, CI [0.54-0.74], P < 0.0001) and hyperlipidemia (OR 0.63, CI [0.51-0.77], P < 0.0001) were found to be protective against TC. Patients with TC after acute SAH were more likely to undergo endovascular coiling (OR 1.68, CI [1.327-2.127], P < 0.001) rather than surgical clipping (OR 0.66, CI [0.52-0.83], P < 0.0001). CONCLUSIONS: Female sex, white ethnicity, smoking and seizures represented significant predictors of developing TC after aSAH, while hypercholesterolemia and hypertension were protective.

Skull bone graft failure is a potential complication of autologous cranioplasty after decompressive craniectomy (DC). Our objective was to investigate the association of graft size with subsequent bone graft failure after autologous cranioplasty. This single-center retrospective cohort study included patients age ≥18 years who underwent primary autologous cranioplasty between 2010 and 2017. The primary outcome was bone flap failure requiring graft removal. Demographic, clinical, and radiographic factors were recorded; three-dimensional (3D) reconstructive imaging was used to perform accurate measurements. Univariate and multi-variate regression analysis were performed to identify risk factors for the primary outcome. Of the 131 patients who underwent primary autologous cranioplasty, 25 (19.0%) underwent removal of the graft after identification of bone flap necrosis on computed tomography (CT); 16 (64%) of these were culture positive. The mean surface area of craniectomy defect was 128.5 cm2 for patients with bone necrosis and 114.9 cm2 for those without bone necrosis. Linear regression analysis demonstrated that size of craniectomy defect was independently associated with subsequent bone flap failure; logistic regression analysis demonstrated a defect area >125 cm2 was independently associated with failure (odds ratio [OR] 3.29; confidence interval [CI]: 0.249-2.135). Patient- and operation-specific variables were not significant predictors of bone necrosis. Our results showed that increased size of antecedent DC is an independent risk factor for bone flap failure after autologous cranioplasty. Given these findings, clinicians should consider the increased potential of bone flap failure after autologous cranioplasty among patients whose initial DC was >125 cm2.
RESUMEN
OBJECTIVE: This study investigates the effect of aneurysm circulation on mortality and patient outcomes after aneurysmal subarachnoid hemorrhage (SAH) within the United States. METHODS: A retrospective cohort study was conducted using the Nationwide Inpatient Sample (NIS), a part of the Healthcare Cost and Utilization Project (HCUP), with ICD-10 codes for non-traumatic SAH between 2015-2016. Aneurysms were stratified as either anterior or posterior circulation. Multivariate logistic regression was used to find the impact of selected variables on the odds of mortality. RESULTS: The NIS reported 1,892 cases of non-traumatic SAH within the study period that were predominantly anterior circulation (82.6%), female (68.6%), white (57.7%), with mean age of 59.07 years, and in-hospital mortality of 21.4%. Anterior circulation aneurysms were associated with lower severity of initial illness (pâ¯=â¯0.014) but higher likelihood of vasospasm (pâ¯=â¯0.0006) than those of the posterior circulation. In a multivariate logistic regression analysis, mortality was associated with posterior circulation aneurysms (OR: 1.42; CI 95% 1.005-20.10, pâ¯=â¯0.047), increasing age (OR: 1.035; 95% CI 1.022-1.049; p < 0.0001), and shorter hospital stays (OR: 0.7838; 95% CI 0.758-0.811; p < 0.0001). Smoking history (OR: 0.825; 95% CI 0.573-1.187, p > 0.05) and vasospasm (OR: 1.005; 95% CI 0.648-1.558; p > 0.05) were not significantly associated with higher odds of mortality. CONCLUSIONS: Mortality following aneurysmal SAH is associated with posterior circulation aneurysms, and increasing age, but not smoking history or vasospasm. These findings may be useful for prognostication and counseling patients and families.

BACKGROUND: This report highlights a rapidly progressive case of Creutzfeldt-Jakob Disease (CJD) whose time from symptom onset to death spanned less than two months. We also explore the most recently available in-patient demographics data for discharges with CJD in the United States. METHODS: We reviewed a CJD case and systematically analyzed a retrospective cohort of CJD discharges using the Healthcare Cost and Utilization Project (HCUP) to evaluate the existing national data on the status of CJD demographics and dispositions in the United States in 2016. RESULTS: An estimated total of 710 hospital discharges with a diagnosis of CJD were seen across the United States in 2016. According to HCUP, the average age of patients was 66.15⯱â¯11.54 years with 48.6 % female. Average time to intubation from admission to hospital was 4.71⯱â¯7.32 days with a rate of intubation of 6.34 %. The mean hospital cost was $19,901.25 ± $18,743.48. The rate of in-hospital mortality was 8.45 %. No significant geographical differences were noted (pâ¯=â¯0.49). No significant differences were seen among incidence in specific ethnic groups (pâ¯=â¯0.33) or income quartiles (pâ¯=â¯0.90). CONCLUSIONS: Our data shows that the incidence of CJD in 2016 appears to be equally distributed among individuals in the United States by demographic categories. Additionally, our case-study from 2019 illustrates an important example for diagnosing a rapidly-progressing case of CJD.

OBJECTIVES: The epidemiological analysis of brain death (BD) can assist physicians in their development of relevant guidelines regarding training and action protocols. This study aims to find the incidence of BD in the United States. PATIENTS AND METHODS: This is a cross-sectional study between 2012 and 2016 in the United States. BD data were extracted from the Healthcare Cost and Utilization Project (HCUP) and compared with those of all in-hospital Cardio-Pulmonary Deaths (ih-CPD). RESULTS: There were 69,735 BD (0.039%) and 3,309,955 ih-CPD (1.85%) with one BD for every fifty ih-CPD. The number of BD increased from 12,575 in 2012 to 15,405 in 2016 (p < 0.0001), with an average of 39 BD per 100,000 discharges and a mean age of 47.83 ± 20.93 years old. Both groups were mainly male and ethnically white; however blacks had the highest rate of BD per capita (p < 0.0001). The most frequently reported cause for BD was the Central Nervous System diseases (50.17%). CONCLUSIONS: In recent years, the incidence of BD has increased in the United States. Knowing the incidence of BD and the establishment of long-term programs that raise awareness about BD may increase the number of potential organ donors in the future.

BACKGROUND: The ARUBA trial (A Randomized Trial of Unruptured Brain Arteriovenous Malformations) was the first randomized control trial to investigate unruptured cerebral arteriovenous malformation (cAVM) treatments and concluded that medical management was superior to interventional therapy for the treatment of unruptured cAVMs. This conclusion generated considerable controversy and was followed by rebuttals and meta-analyses of the ARUBA methodology and results. We sought to determine whether the ARUBA results altered treatment trends of cAVMs within the United States. METHODS: Using the National Inpatient Sample, the largest all-payer inpatient care database within the United States, we isolated patients who were admitted on an elective basis for cAVM treatment and determined the treatment modality undergone by these patients. The cohort was dichotomized separately at 2 ARUBA time points: the European Stroke Conference presentation in May 2013, and The Lancet publication in February 2014. RESULTS: We found that the overall treatment rate of unruptured cAVMs decreased after both time points. However, the rate of surgical excision alone, relative to other modalities, was significantly increased, and endovascular intervention demonstrated a nonsignificant decrease. CONCLUSIONS: Our findings suggest that the ARUBA trial has influenced unruptured cAVM treatment patterns within the United States. Although the overall treatment rate has decreased, unruptured cAVMs, when treated post-ARUBA, are most commonly approached with surgical excision alone.

BACKGROUND: Socio-demographic factors have been suggested to contribute to differences in healthcare utilization for several elective orthopedic procedures. Reports on disparities in utilization of orthopedic trauma procedures remain limited. The purpose of our study is to assess the roles of clinical and socio-demographic variables in utilization of operative fixation of calcaneus fractures in the USA. METHODS: The National Inpatient Sample (NIS) dataset was used to analyze all patients from 2005 to 2014 with closed calcaneal fractures. Multivariate logistic regression analyses were performed to evaluate the impact of clinical and socio-demographic variables on the utilization of surgical versus non-surgical treatment. RESULTS: A total of 17,156 patients with closed calcaneus fractures were identified. Operative treatment was rendered in 7039 patients (41.03%). A multivariate logistic regression demonstrated multiple clinical and socio-demographic factors to significantly influence the utilization of surgical treatment including age, gender, insurance status, race/ethnicity, income, diabetes, peripheral vascular disease, psychosis, drug abuse, and alcohol abuse (p < 0.05). In addition, hospital size and hospital type (teaching versus non-teaching) showed a statistically significant difference (p < 0.05). CONCLUSIONS: Besides different clinical variables, we identified several socio-demographic factors influencing the utilization of surgical treatment of calcaneus fractures in the US patient population. Further studies need to identify the specific patient-related, provider-related, and system-related factors leading to these disparities.

OBJECTIVE: The management of patients suffering traumatic brain injury (TBI) in the context of multiple significant trauma represents one of the most challenging scenarios in trauma critical care. The identification of risk factors, utilizing large national databases, may help in developing medical strategies and health care policies aimed at improving outcomes in these patients. In this study, our aim was to assess in-hospital mortality following craniotomy for multiple significant trauma in the United States. PATIENT AND METHODS: A retrospective cohort study was conducted using the Nationwide Inpatient Sample (NIS) on subjects having "Craniotomy with Multiple Significant Trauma" between 2008-2016. Multivariate logistic regression was used to find the impact of selected variables on the odds of mortality. RESULTS: There were 26,650 discharges within the study period that were predominantly male (73.2%), white (65.1%), with a mean age of 39.7 ± 22.3, and in-hospital mortality of 35.4%. During the study period, the mortality of this population increased from 34.8% to 38.3% (p = 0.18). In a multivariate logistic regression analysis, the following conditions were associated with higher mortality: being on pressors (OR: 8.41; CI 95% 5.55-12.75, p = 0), having Status Epilepticus (OR: 3.33; CI 95% 1.26-8.81, p = 0.015), self-pay (OR: 4.81; CI 95% 1.49-2.59, p = 0), privately insured (OR: 1.97; CI 95% 1.49-2.59, p = 0) and discharge from urban teaching hospitals (OR = 1.4; CI 95% 1.16-1.68, p = 0). CONCLUSION: Patients who underwent craniotomy with multiple significant trauma had high mortality, at a rate of about one in three; mortality has been increasing during recent years. Those who required vasopressors and those who developed Status Epilepticus had a significant association with higher death. These associations may be due to the complexity of injuries in this population. Patients with these conditions should seek further attention by the clinicians. Further studies are warranted to characterize these differences.

OBJECTIVES: The purpose of this study was to identify the incidence of anesthetic errors per discharges in the United States within these errors, the incidence of death. A secondary aim was to identify any association between the mortality and patient comorbidities. METHODS: A retrospective analysis of the hospitals in the United States using the Nationwide Inpatient Sample (NIS) database during 2007-2014 was performed. The study population consisted of patients who were recorded as inpatient discharges who experienced complications as a result of incorrect anesthetic administration resulting from either an overdose or inappropriate medication administration in the United States. RESULTS: Between 2007 and 2014, a total of 17,116 anesthetic errors were reported. There was a substantial decrease in the total number of these errors over time, from 2483 in 2007 to 1391 in 2014 (44% decrease). There were 131 reported deaths in this cohort (0.77% mortality rate), with 61 mortalities in teaching hospitals (0.86% mortality rate) and 57 in nonteaching hospitals (0.73% mortality rate). During the study period, deaths decreased from 21 in 2007 (0.85% mortality rate) to 11 in 2014 (0.79% mortality rate), corresponding with a 7.1% decrease in the mortality rate. Comorbidities associated with a significant increase in mortality from anesthetic substances included fluid and electrolyte disorders (odds ratio 8.82, 95% confidence interval 5.24-14.83, P < 0.001) and coagulopathies (odds ratio 5.26, 95% confidence interval 2.53-10.93, P < 0.001). CONCLUSIONS: Our study showed that although the incidence of anesthetic errors is small, they do still exist in our hospitals. Certain comorbidities appear to predispose patients to increased risk. The subsets of patients who appear to be at the greatest risk include those with preexisting electrolyte and fluid disorders and coagulopathies.

OBJECTIVES: Over the last two decades, various studies have evaluated the impact of weekend admission to the hospital on inpatient mortality. Our study sought to identify whether or not the "weekend effect" was true for patients with Intracranial Hemorrhage (ICH) admitted to United States hospitals and whether or not the introduction of comprehensive stroke centers (CSCs) made an impact on the "weekend effect" for ICH. PATIENTS AND METHODS: Searched the Nationwide Inpatient Sample for the ICH discharges between 2006 and 2014. Multivariate regression analysis was performed to evaluate the factors that impacted in-hospital mortality. Additional subgroup analysis was performed based on two time periods, before CSCs (2006-2009) and afterward (2010-2014). RESULTS: 146,587 discharges with ICH were reported by the NIS with 37,471 (25.6%) weekend admissions. The weekday admission cohort was 50.6% male with a mean age of 67.1 years. There was a total of 35,362 deaths among ICH admissions. The in-hospital mortality rate was significantly higher for weekend admissions compared to that of weekday admissions (25.2% vs. 23.8%, pâ¯<â¯0.001). Multivariate analysis of mortality for the 2006-2009 subgroup demonstrated a statistically significant higher odds of death with weekend admission (ORâ¯=â¯1.15, 95% CI [1.10, 1.20], pâ¯=â¯0) but not for the 2010-2014 subgroup (ORâ¯=â¯1.03, 95% CI [0.99, 1.07], pâ¯=â¯0.09). CONCLUSION: Our study showed that in-hospital mortality was found to be increased for patients with ICH admitted on a weekend; however, this association was lost after the initiation of CSCs. Further prospective studies are warranted to gain a better understanding regarding this association.

OBJECTIVE: Multiple studies have shown worse outcomes in patients admitted for medical and surgical conditions on the weekend. However, past literature analyzing this "weekend effect" on subarachnoid hemorrhage (SAH) found no significant increase in mortality. This study utilizes more recent data to re-evaluate the association between weekend admission and mortality of patients hospitalized for SAH. METHODS: This retrospective cohort study queried the SAH patients in the Nationwide Inpatient Sample (NIS) database who were discharged from 2006 through 2014 during the weekend. RESULTS: Of the 54,703 admissions for SAH identified during the study period, 14,821 (27.1%) occurred over the weekend. Patients admitted over the weekend had a mean age of 59.2 years and were most likely to be female (59.6%), to be white (62.9%), located in the south region of the USA (40.1%), and be admitted to a teaching hospital (74.4%). When compared directly to weekday admissions, patients admitted over the weekend had higher odds of in-hospital mortality (odds ratio 1.07; confidence interval 95%, 1.02-1.12). There was no significant difference shown in the rate patients get surgical clipping versus endovascular coiling (p = 0.28) or the amount of time between admission to procedure for clipping (p = 0.473) or coiling (p = 0.255) on the weekend versus a weekday. CONCLUSION: Based on our findings, the likelihood of the in-hospital mortality was higher for patients admitted over the weekend. However, the characteristics of the study, primarily observational, prevent us arriving at an accurate conclusion about why this occurs; hence, we believe it is an important starting point to consider for future research.
