RESUMEN
OBJECTIVE: To investigate the differences in risk factors and in-hospital outcomes for women undergoing percutaneous coronary intervention (PCI) and peripheral vascular intervention (PVI). BACKGROUND: The clinical impact of coronary artery disease (CAD) and peripheral artery disease (PAD) is well characterized and is associated with high morbidity and mortality. There is lack of data comparing risk factors and in-hospital outcomes for PCI and PVI, particularly in women. METHODS: Only female hospitalizations (age ≥ 18 years) who underwent PCI or PVI from 2005 to 2014 were identified using appropriate International Classification of Diseases-Ninth Revision, Clinical Modification codes from the National Inpatient Sample database. Charlson's Comorbidity Index (CCI) was selected as the primary endpoint of the study. Coprimary endpoint was the cost of hospitalizations associated with PCI or PVI. RESULTS: Of the 2,461,328 female hospitalizations that were included, 85.6% (N = 2,105,236) underwent PCI and 14.4% (N = 356,092) received PVI. Compared to PCI, PVI hospitalizations were 3.2 years older (p < .001) and consisted of significantly more hospitalizations above 80 years of age (26.5% vs. 18.6%; p < .001). Hospitalizations with CCI ≥3 were significantly higher in the PVI cohort (29.1% vs. 24%; p < .001). CCI in women increased during the study period for both groups. PVI hospitalizations had a significantly longer length of stay (3 days vs. 2 days; p < .001) and cost of hospitalization ($23,610 vs. $20,571; p < .001), compared to PCI. Finally, the mean cost of hospitalizations increased during the study period for PCI and PVI. CONCLUSION: Women hospitalized for PVI had a greater risk-profile and resource utilization as demonstrated by the longer length of stay and higher cost compared to PCI.

GOALS: The goal of this study was to evaluate the impact of obesity on the outcomes of patients with lower gastrointestinal hemorrhage (LGIH). BACKGROUND: Obesity is considered as an independent risk factor for LGIH. We sought to analyze in-hospital outcomes and characteristics of nonobese and obese patients who presented with LGIH, and further, identify resource utilization during their hospital stay. MATERIALS AND METHODS: With the use of National Inpatient Sample from January 2005 through December 2014, LGIH-related hospitalizations (age≥18 y) were identified using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic codes. Patients were stratified into the nonobese and obese groups depending on their body mass index (>30 kg/m). The statistical analyses were performed using SAS 9.4. RESULTS: Of the total 482,711 patients with LGIH-related hospitalizations, 38,592 patients were found to be obese. In a propensity-matched analysis, the in-hospital mortality was higher in the nonobese patients (4.2% vs. 3.8%, P=0.004), however, the mean length of hospital stay and mean cost was higher in the obese group which could be due to a higher number of comorbidities in the obese group. Secondary outcomes such as the need for mechanical ventilation vasopressor use and colonoscopy was significantly higher in the obese group. CONCLUSIONS: The study results demonstrate that 'obesity paradox' do exist for LGIH-related hospitalizations for mortality. LGIH hospitalizations in the obese patients are associated with higher resource utilization as evidenced by the longer length of stay and higher cost of hospitalizations as compared with the nonobese patients.

To gain understanding of the burden of cardiac arrhythmias in patients with acutely decompensated diabetes mellitus (ADDM) on a large scale, we reviewed data on ADDM patients and subtypes of arrhythmias from the National Inpatient Sample from 2010 to 2014. The frequency and prevalence of cardiac arrhythmias were measured, as well as outcomes. Among 874,107 hospitalized ADDM patients identified, 87,970 (10.1%) developed arrhythmias. The ADDM-arrhythmia cohort showed higher all-cause mortality (1.4% vs 0.3%; adjusted odds ratio 2.58, 95% confidence interval 2.39-2.79, P < 0.001), prolonged hospital stays (4.2 ± 4.8 vs 3.3 ± 3.4 days), and higher hospital charges ($32,609 vs $23,741) compared to those without arrhythmias (P < 0.001). The prevalence of supraventricular arrhythmia (atrial fibrillation, supraventricular tachycardia, and atrial flutter) and ventricular arrhythmia (ventricular tachycardia and ventricular fibrillation) was 2965 and 446 per 100,000 ADDM-related hospitalizations, respectively. The prevalence of any arrhythmias and atrial fibrillation in ADDM patients increased by 20.4% and 38.1%, respectively. The highest increase in the prevalence of arrhythmia among ADDM patients was observed in adults aged 18 to 44 years (22.5%).
RESUMEN
We aimed to study the impact of Hepatic Cirrhosis (HC) on chronic obstructive pulmonary disease (COPD). Our study is a retrospective cohort study using the 2016-2017 National Readmission Database (NRD). NRD is part of the Healthcare Cost and Utilization Project (HCUP), organized and supported by means of the Agency for Healthcare Research and Quality (AHRQ). Patients were included if they were 18 years or older and had a principal diagnosis of COPD based on International Classification of Diseases, Tenth Revision (ICD-10- CM) codes and had a secondary diagnosis of HC. A total of 505,004 patients were included in the study with a diagnosis of COPD, 6196 (1.23%) of whom had HC. HC was found to be more common amongst male patients between the ages of 50 and 65 years. Medicare beneficiaries with high comorbidity burden, lower socioeconomic status, and those who received treatment in a large urban teaching hospital also had higher rates of HC. Patients with HC and COPD correlated to an increase of in-hospital mortality (adjusted odds ratio (aOR: 2.21, p<0.001) and 30-day hospital readmission rate (aOR: 1.23, p<0.001) compared with patients without HC. The in-hospital mortality rate was higher during readmission compared with index admissions (5.01% versus 2.16%; p<0.001). In addition, HC was associated with higher morbidity including prolonged mechanical ventilation (aOR: 1.39, p<0.001), resource utilization with prolong length of stay (LOS) (adjusted mean difference (aMD: 0.51, p<0.001), higher total hospitalization charges (aMD: 4967, p<0.001), and costs (aMD: 1200, p<0.001). Both patient groups had similar odds of being intubated (aOR: 1.18, p-0.13), tracheostomy (aOR: 0.81, p-069) and bronchoscopy rates (aOR: 1.27, p-0.36). The most common causes of hospital readmission were found to be COPD with acute exacerbation (19.7%), sepsis, unspecified organism (6.0%, acute and chronic respiratory failure with hypoxia (4.2%), acute on chronic systolic heart failure (3.9%), and hepatic failure, unspecified coma (3.1%). Various autonomous prognosticators of readmission were sex (particularly female), alcohol dependence, LOS greater than 7 days, lower comorbidity burden, and discharge to short term hospital or against medical advice. On the other hand, males, patients without a history of alcohol dependence, greater comorbidity burden, and LOS fewer than 3 days, were less likely to be readmitted. We found that HC is related to higher in-hospital mortality, LOS, increased mechanical ventilation, resource utilization with prolonged LOS, hospital costs, odds of intubation, and tracheostomy and bronchoscopy rates. Our study aims to shed light on the impact of HC on COPD in hopes to improve future management.
RESUMEN
We aim to study the impact of pulmonary hypertension on acutely exacerbated chronic obstructive pulmonary disease (AECOPD). We used the 2016 and 2017 National Readmission Database with an inclusion criterion of AECOPD as a primary and pulmonary hypertension as a secondary diagnosis using ICD 10-CM codes. Exclusion criteria were age under 18 years, non-elective admission, and discharge in December. The primary outcome was in-hospital mortality during the index admission. Secondary outcomes were 30-day readmission rate, resource utilization, and instrument utilization including intubation, prolonged invasive mechanical ventilation >96 h (PIMV), tracheostomy, chest tube placement, and bronchoscopy during the index admission. A total of 627,848 patients with AECOPD were included in the study, and 68,429 (10.90%) patients had a diagnosis of pulmonary hypertension. Pulmonary hypertension was more common among females (61.14%) with a mean age of 71 ± 11.66, Medicare recipients (79.5%), higher Charlson comorbidity index, and treatment in an urban teaching hospital. Pulmonary hypertension was associated with greater mortality (adjusted odds ratio (aOR) 1.89, p < 0.001), higher 30-day readmission (aOR 1.24, p < 0.001), higher cost (adjusted mean difference (aMD) $2785, p < 0.01), length of stay (aMD 1.09, p < 0.001), and higher instrument utilization including intubation (aOR 199, p < 0.001), PIMV (aOR 2.12, p < 0.001), tracheostomy (aOR 2.1, p < 0.001), bronchoscopy (aOR 1.46, p = 0.007), and chest tube placement (aOR 1.39 p < 0.004). We found that pulmonary hypertension is related to higher in-hospital mortality, length of stay, increased instrument utilization, readmission, and costs. Our study aims to shed light on the impact of pulmonary hypertension on AECOPD in hopes to improve future management.
RESUMEN
BACKGROUND: Secondary spontaneous pneumothorax (SSP) is defined as a pneumothorax presenting as a complication of underlying lung disease. Due to the high recurrence rate and the possibility of life-threatening complications, same-admission recurrence prophylaxis (SARP) following the first occurrence of SSP is recommended by many experts. The rate of SARP in SSP admissions has not been reported. RESEARCH QUESTION: How often were SARP procedures performed in SSP admissions in the United States? How did outcomes differ between SSP admissions with SARP vs those without SARP? STUDY DESIGN AND METHODS: This study used the Nationwide Readmission Database to analyze 71,451,419 inpatient admissions in the United States in 2016 and 2017. SSP admissions with patients aged ≥ 18 years were included, and admissions with documented traumatic or iatrogenic causes of pneumothorax were excluded. Outcomes were compared between SSP admissions with and without SARP. Multivariate logistic analysis was used to model binary-dependent variables. RESULTS: There were 21,838 SSP admissions in 2016 and 2017 (30.56 per 100,000 admissions per year), among which 7,366 (33.73%) received SARP. SARP was associated with lower odds of in-hospital mortality (adjusted OR [aOR], 0.48; 95% CI, 0.34-0.70), 30-day mortality (aOR, 0.52; 95% CI, 0.35-0.77), 90-day mortality (aOR, 0.56; 95% CI, 0.40-0.79), and 1-year mortality (aOR, 0.28; 95% CI, 0.10-0.74). SARP was also associated with lower all-cause readmission at 30 days (aOR, 0.40; 95% CI, 0.40-0.49), 90 days (aOR, 0.47; 95% CI, 0.40-0.55), and 1 year (aOR, 0.46; 95% CI, 0.30-0.68), as well as lower rates of postdischarge pneumothorax recurrence in 30 days (aOR, 0.22; 95% CI, 0.11-0.44), 90 days (aOR, 0.26; 95% CI, 0.20-0.33), and 1 year (aOR, 0.22; 95% CI, 0.11-0.44). INTERPRETATION: The rate of SARP in SSP admissions was 33.73% in the United States in 2016 and 2017. SARP was associated with lower mortality, all-cause readmission, and pneumothorax recurrence in SSP admissions.

INTRODUCTION: Atrial fibrillation is the most frequently occurring and studied arrhythmia. There is a limited data on young patients presenting with atrial fibrillation. OBJECTIVE: The objective of this research article was to assess the trend of hospitalization, epidemiological characteristics and economic burden in the young adult, aged 18-45 years, presenting with atrial fibrillation. METHODS: Hospitalization data from the National Inpatient Sample between 2005 and 2015 were used to analyze prevalence of risk factors and financial burden in young adults with atrial fibrillation. RESULTS: From 2005 to 2015, a total of 260,080 admissions were included in the study. From 2005 to 2015, there was a decreasing trend of total admissions with atrial fibrillation among the age group of 18-45 years compared to total admissions due to atrial fibrillation and total population. However, there was an increasing trend of admission observed in young females, white and black population. The frequency of hypertension, diabetes and obesity among young adults admitted with atrial fibrillation nearly doubled from 2005 to 2015. There was also a marked increase in the frequency of obstructive sleep apnea, alcohol abuse and drug abuse among patients admitted with atrial fibrillation. Furthermore, there was an increase in the mean cost of hospitalization from $7363 in 2005 to $7924 in 2015, Ptrend < 0.001. CONCLUSION: In conclusion, increased cardiovascular risk factors among young adult with admissions for atrial fibrillation warrants controlling of the risk factors to further curtail hospitalizations.

BACKGROUND: Thyroid dysfunction has been associated with cardiovascular dysfunction in the literature. However, the frequency of new-onset arrhythmias associated with thyroid disease hospitalization is unknown. Hence, we analyzed frequency, in-hospital outcomes, and resource utilization of new-onset arrhythmias associated with thyroid dysfunction hospitalizations. METHODS: The patients who were admitted with the primary reason of thyroid dysfunction were included using appropriate international classification of disease, ninth revision, clinical modification (ICD-9-CM) codes. We then identified new-onset arrhythmias using appropriate ICD-9-CM codes. We utilized the "present on admission" variable to exclude arrhythmias that were present on admission. RESULTS: Among the eligible patients with thyroid dysfunction, only 3% (n=12,111) developed a new-onset arrhythmia. Atrioventricular block (1.49%) is the most frequent followed by atrial fibrillation (0.92%), ventricular tachycardia (0.47%), atrial flutter (0.23%), supraventricular tachycardia (0.1%) and ventricular fibrillation (0.07%). Patients with new-onset arrhythmias were older (mean age 76.7±12.5 years), more predominantly white (n=9008, 74.4%), higher females (n= 7632, 63%), and had a higher frequency of comorbidities. In-hospital mortality occurred in 827 (6.8%) patients with new-onset arrhythmias and 8632 (2.2%) patients without new-onset arrhythmias (P-value <0.001). The medical length of stay and cost of hospitalization was also higher in these patients. CONCLUSION: Thyroid dysfunction is not associated with significantly higher rates of new-onset arrhythmias while inpatient. However, when developed, these arrhythmias are associated with higher mortality and resource utilization. The patients admitted to the hospital should have thyroid function checked when found to have an arrhythmia.
