Study Design: Retrospective trends analysis. Objectives: Cervical fusion is a common adjunctive surgical modality used in the treatment of cervical spondylotic myelopathy (CSM). The purpose of this study was to quantify national trends in patient demographics, hospital characteristics, and outcomes in the surgical management of CSM. Methods: This was a retrospective study that used the National Inpatient Sample. The sample included all patients over 18 years of age with a diagnosis of CSM who underwent cervical fusion from 2003 to 2013. The outcome measures were in-hospital mortality, length of stay, and hospital charges. Chi-square tests were performed to compare categorical variables. Independent t tests were performed to compare continuous variables. Results: We identified 62 970 patients with CSM who underwent cervical fusion from 2003 to 2013. The number of fusions performed per year in the treatment of CSM increased from 3879 to 8181. The average age of all fusion patients increased from 58.2 to 60.6 years ( P < .001). Length of stay did not change significantly from a mean of 3.7 days. In-hospital mortality decreased from 0.6% to 0.3% ( P < .01). Hospital charges increased from $49 445 to $92 040 ( P < .001). Conclusions: This study showed a dramatic increase in cervical fusions to treat CSM from 2003 to 2013 concomitant with increasing age of the patient population. Despite increases in average age and number of comorbidities, length of stay remained constant and a decrease in mortality was seen across the study period. However, hospital charges increased dramatically.

e19016 Background: Perianal infection is a rare and poorly understood complication of patients with acute myeloid/lymphocytic leukemia (AML/ALL). With the advancements in oncology, patients are living longer in an immunocompromised state and thus bearing the inherent problems such as infections that arise with it. Perianal infection and its management impacts patients' quality of life as well as interrupts their ongoing oncologic treatment. The optimal treatment strategy for perianal infections in this highly immunocompromised group remains unclear, as does the selection and outcomes of patients for operative intervention. The aim of this study is to identify patient characteristics associated with perianal infection and to delineate outcomes in patients that undergo operative intervention. Methods: The National Inpatient Sample (NIS) database was used to identify hospitalized patients with diagnoses of perianal abscess and AML/ALL between 2007 and 2015. Patient data were weighted to obtain national estimates. Demographics and clinical characteristics were compared between patients with and without perianal disease using Rao-Scott Chi-square test for categorical variables, and weighted simple linear regression for continuous variables. Characteristics and outcomes were compared between patients who underwent operative or non-operative management. Results: There were 12,626 (0.7%) patients with perianal disease among 1,782,778 AML/ALL patient admissions. Patients with perianal disease were more likely to be younger (43.9 (42.5 – 45.3) years, p < 0.001), male (67.4% vs 32.6%, p < 0.001) and white (65.8% vs 54.8%, p < 0.001). Length of stay (18.4 days vs 9 days, p < 0.001) and hospital cost ($54K vs $25K, p < 0.001) were higher in those with perianal disease, but there was no difference in in-hospital mortality (5.5% in those with perianal diseases vs 6.2% in those without, p = 0.150). Greater proportion of patients without perianal disease were discharged to hospice (12.6% patients without perianal disease vs 5.1% patients with perianal disease, p < 0.001). Receiving a surgical intervention did not improve outcomes with respect to in-hospital mortality (5.9% operative vs 5.4 non-operative, p = 0.596), length of stay (20.2 days vs 18.2 days, p = 0.582) or hospital cost ($67K vs $53K, p = 0.525). Conclusions: Perianal disease is a rare but distressing complication in AML/ALL patients associated with longer hospital stays and higher hospital costs. Operative intervention for perianal disease did not reduce rates of in-hospital mortality, length of stay or hospital cost but it does impact the probability of discharge to hospice. Non-operative and operative intervention both remain equivocal in changing the outcomes these patients. Further studies are required to examine these associations and determine best practices for treatment of this condition in this complex patient population.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Atrial fibrillation is a common disorder in the elderly population and a known risk factor for stroke and dementia. Purpose  To study the burden of dementia in Afib hospitalizations and identify the predictors of in-hospital mortality in Afib with dementia hospitalizations. Methods We queried January 2016 to December 2018 National Inpatient Sample (NIS) to identify adult (≥18 yrs) hospitalizations with a primary diagnosis of Afib. Hospitalizations of Afib with dementia was compared with Afib without dementia. We used the Chi-square test for differences between categorical variables, and Student’s t-test for continuous variables. Multivariate logistic regression was used in outcomes analysis to adjust for potential hospital and patient-level confounders. Results  We identified 1,236,540 weighted Afib hospitalizations across three years. Of which, 79,405 (6.4%) of them were associated with dementia. Afib with dementia hospitalizations were associated with older age (mean age 83.2 vs 70.0 yrs; P &lt; 0.01), higher rate of chronic Afib (15.3% vs 7.5%; P &lt; 0.01), higher rate of comorbidity (% of &gt;3 Elixhauser comorbidity score 91.8% vs 83.6%; P &lt; 0.01). After adjusting for patient and hospital-level characteristics, we observed that Afib with dementia hospitalizations was associated with higher odds of in-hospital mortality compared to Afib without dementia [Odds Ratio (OR): 1.6 (1.4 – 1.9); P &lt; 0.01]. We also observed statistically significant association with increased LOS [4.7 vs 3.2 days; P &lt; 0.01], repeated falls [OR: 2.8 (2.5 – 3.1); P &lt; 0.01] and protein calorie malnutrition [OR: 1.9 (1.7 – 2.0); P &lt; 0.01] in Afib with dementia group. Conclusion Afib with dementia hospitalizations are not only associated with higher mortality, but they are also associated with higher repeated fall rates, and skilled nursing facility discharge dispositions. Co-morbidities like hypertension, CKD, obesity, HFrEF, HFpEF, OSA are associated with higher in-hospital mortality. Our study findings emphasize the burden of dementia in Afib hospitalizations and the need for prevention of poor outcomes in this population.

Background: Warfarin anticoagulation presents a common barrier to undergoing cardiac catheterization procedures. Using radial access and other bleeding mitigation strategies, it is not known if elevated INR truly portends an increased risk of adverse events. We sought to understand the relationship between in hospital mortality and bleeding with INR in patients undergoing coronary interventional catheterization procedures. Methods: The prospectively-collected Dartmouth Dynamic Registry was queried for all patients who underwent catheterization with coronary intervention from 2014 to 2018. Of the 5015 patients identified, 2120 patients had a recorded INR value within 24 hours of the procedure. Demographics, procedural variables, and in hospital outcomes were collected. Patients were divided into two groups: INR &lt1.8 and INR &gt1.8. Incidence of bleeding (access site hematoma &gt5cm, post procedure blood transfusion) as well as in-hospital mortality were queried for each group. Stata was used to determine statistical significance, using chi-square analysis for categorical variables and standard t-test for continuous variables. Results: Of the 2120 patients with INR values, 1968 patients were identified with INR &lt1.8 (median INR 1.1; range 0.7-1.7) and 152 patients with INR &gt1.8 (median INR 2.2; range 1.8-11.1). Patients with elevated INRs had higher acuity (urgent or emergent cases) and were older. Other baseline and procedural characteristics were similar. Outcomes between those with elevated INR and those with lower INR values were similar, including access site injury, hematoma, and need for transfusion (Table I). Overall mortality did not differ between the two groups. Conclusion: When compared to patients with INR &lt1.8, patients with INR &gt1.8 are more likely to undergo coronary intervention on an urgent or emergent basis. Despite this, there is no difference in bleeding, need for transfusion, or overall in-hospital mortality.

Abstract Background Early pathogen identification and initiation of appropriate antimicrobial therapy is key in the management of Gram-negative rods (GNR) bloodstream infection (BSI). The Accelerate Pheno System (ACC) has been shown to reduce time to GNR identification compared to traditional culture-based methods. We aimed to determine the impact of ACC on the management of GNR BSI in the setting of a well-established antimicrobial stewardship program (ASP). Table 1 Methods ACC was introduced in our institution on February 2019. Due to issues incorporating ACC, of patients with GNR BSI, 74% had ACC done and 26% had reporting through traditional methods. This allowed for the design of a retrospective cohort study (instead of a pre-post analysis) to evaluate the association of interest. We included adult patients admitted to three affiliated hospitals in Des Moines, Iowa with BSI due to Enterobacteriales from February 2019 to February 2020. Exclusion criteria were Emergency Department visit only and death within 48 hours of blood culture collection. Primary outcomes were length of hospital stay, days to therapy optimization and in-hospital mortality. Continuous variables were compared by non-parametric methods and categorical variables were compared by Chi-square and Fisher-exact test. Logistic regression models were used to calculate odds ratio for the impact of the intervention on therapy optimization. Results A total of 268 patients were analyzed. The median length of stay among patients who had ACC done was 5.2 days (IQR 3.6–8.7) and in those on who ACC was not done it was 5.5 (IQR 3.8–8.9) (p=0.54). No differences in in-hospital mortality were found (p=0.942). Changes in therapy and missed opportunities for optimization according to whether ACC was done are shown in Table 1. Patients who had ACC done had 99% higher odds of de-escalation within 48 hours of blood culture collection compared to patients who did not have it done (95% CI 1.01–3.92; p=0.044). Conclusion In the context of hospitals with baseline short length of stay and a well-established ASP, performing ACC was associated with higher odds of de-escalation within 48 hours of blood culture collection but did not impact length of stay or mortality among patients hospitalized with GNR BSI.

Abstract Background: Several studies have demonstrated the deleterious effects of anticholinergic drugs on the cognitive functions of the elderly. However, their effects on the onset of delirium have produced conflicting results. We assessed the association of the anticholinergic burden of treatment at admission according to 3 anticholinergic scales, the ADS, the modified ADS (mADS) and the Marante Scale on the onset of delirium in elderly hospitalized patients. We also analyzed the inter-rater reliability of the scales and their prognostic value in terms of length of stay and hospital mortality.Methods: This retrospective study included patients over 75 years of age hospitalized in medical and surgical departments between January 2014 and June 2019. Delirium was diagnosed by the Confusion Assessment Method (CAM). The anticholinergic burden was assessed by ADS, mADS and Marante Scale in patients with and without delirium.Results were reported as percentages for categorical variables and mean ± standard deviation (SD) and median [interquartile range] for continuous variables after Kolmogorov- Smirnov distribution test. Descriptive statistics were performed using paired Student t-test or Chi-square test. Spearman’s correlation was run to assess the inter-rater reliability between ADS, mADS and the Marante Scale. Results: Among the 1487 patients included, 26% developed delirium. No statistically significant difference in anticholinergic burden was observed between the delirium group and the control group, regardless of the anticholinergic scale used. The correlation coefficient was respectively 0.35 and 0.33 between ADS, mADS and the Marante Scale, and 0.97 between ADS and mADS (all p<0.001). None of the three scales were associated with length of stay, intra-hospital mortality, or one-year mortality. In multivariate analysis, ADS and mADS scores were independently associated with depression (p=0.003 and <0.0001), drug withdrawal (both p<0.001) and the number of drugs on admission (both p<0.001), and Marante Scale score was independently associated with living in a nursing home (p=0.018) and the number of drugs on admission (p<0.0001).Conclusions: Regardless of the scale used, we did not demonstrate a significant association between the anticholinergic burden of treatment upon admission and the onset of delirium during hospitalization.

Background and Objectives: Evidence suggests variations in medical services provided by hospital teaching status. However, there is limited data on how it affects hospital outcomes. The aim of this study is to examine differences in outcomes among patients who underwent multi-vessel percutaneous coronary intervention (MVPCI) stratified by hospital teaching status. Methods: We queried the 2016 Nationwide Inpatient Sample database and identified patients who underwent MVPCI using ICD-10 procedure codes. Hospital teaching status was classified as urban teaching vs. non- teaching. Chi-square and Wilcoxon rank-sum tests were used to compare the following outcomes between hospitals: patient demographics, clinical outcomes, in-hospital mortality, length of stay (LOS), and total charges. Results: Among the 15,611 MVPCI procedures performed, 73.5% were done in teaching hospitals. 68.4% of the MVPCI in teaching hospitals were in males and 54.1% in patients aged ≥65 years. Teaching hospitals had a lower proportion of whites (74.1% vs 79.5%, p<0.001). Teaching and non-teaching hospitals did not differ significantly in impella use (1.7% vs 1.7%, p=0.9928), IABP use (2.2% vs. 2.3%, p=0.7156) and in-hospital mortality (2.0% vs 2.2% p=0.3399). The incidence of acute renal failure (14.0% vs 13.5%, p=0.3858), cardiogenic shock (4.5% vs 4.7%, p=0.5969), cardiac tamponade (0.2% vs 0.2% p=0.5769), and ventricular fibrillation (2.6% vs 2.9%, p=0.2570) did not differ significantly. However, the median length of stay (LOS) (3 vs 2 days, p=0.0075) and hemorrhage requiring transfusion (HRT) (5.6% vs 4.7%, p=0.0414) were significantly greater in teaching centers. In contrast, total hospital charges ($96,465 vs. $106,711, p<0.0001) was lower in teaching centers. Conclusion: Our analysis did not show any differences with regards to in-hospital deaths, IABP use, impella use and many of the hospital outcomes in MVPCI. In teaching centers, the occurrence of HRT and the mean LOS was increased, but there was no increased financial costs.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Obesity is a common and known risk factor for many cardiovascular diseases. Prior studies on chronic systolic heart failure have demonstrated that obesity is inversely associated with mortality, the so-called obesity paradox. Purpose  To study the phenomenon of obesity paradox in HFrEF hospitalizations Methods We queried January 2016 to December 2018 National Inpatient Sample (NIS) to identify adult (≥18 yrs) hospitalizations with a primary diagnosis of HFrEF. Patients with an associated diagnosis of obesity and higher BMI were also identified based on appropriate ICD-10 CM codes. We used the Chi-square test to evaluate the differences between binary or categorical variables, and Student’s t-test for continuous variables. Multivariate logistic regression was used in outcomes analysis to adjust for potential hospital and patient-level confounders. Results  We identified 639,944 weighted HFrEF hospitalizations across three years. Of which, 130,949 (20.4%) of them were associated with obesity. HFrEF with obesity hospitalizations were associated with younger age (mean age 62.0 vs 70.7 yrs; P &lt; 0.01), lesser CAD (55% vs 61%; P &lt; 0.01), higher rate of comorbidity (% of &gt;3 Elixhauser comorbidity score 99.2% vs 94.1%; P &lt; 0.01) and higher Medicaid primary payer (18.2% vs 12.7%, P &lt; 0.01). After adjusting for patient and hospital-level characteristics, we observe statistically significant difference in odds of in-hospital mortality when HFrEF with obesity hospitalizations was compared to HFrEF without obesity [Odds Ratio (OR): 1.1 (0.8 – 1.5); P = 0.52]. We observed statistically significant association with increased LOS [6.0 vs 5.3 days; P &lt; 0.01], increased total hospitalization charges [US$ 61524 vs 55677; P &lt; 0.01] and decreased coronary catheterizations [OR: 0.7 (0.5 – 0.9); P = 0.01] in HFrEF with obesity group compared to HFrEF without obesity. Conclusion In this retrospective cohort of hospitalized patients with HFrEF, higher BMI and obesity was not associated with in-hospital mortality. However, it was associated with longer LOS and higher total hospitalization charges. HFrEF with obesity hospitalizations are associated with lesser left coronary catheterizations. This may be explained by lesser burden of CAD in this patient population.

The purpose of this study is to evaluate the relationship between hydroxychloroquine (HCQ) and diabetic retinopathy (DR) via the national health insurance research database (NHIRD) of Taiwan. All patients with newly diagnosed type 2 diabetes (n = 47,353) in the NHIRD (2000–2012) were enrolled in the study. The case group consists of participants with diabetic ophthalmic complications; 1:1 matching by age (±1 year old), sex, and diagnosis year of diabetes was used to provide an index date for the control group that corresponded to the case group (n = 5550). Chi-square test for categorical variables and Student’s t-test for continuous variables were used. Conditional logistic regression was performed to estimate the adjusted odds ratio (aOR) of DR. The total number of HCQ user was 99 patients (1.8%) in the case group and 93 patients (1.7%) in the control group. Patients with hypertension (aOR = 1.21, 95% CI = 1.11–1.31) and hyperlipidemia (aOR = 1.65, 95% CI = 1.52–1.79) significantly increased the risk of diabetic ophthalmic complications (p < 0.001). Conversely, the use of HCQ and the presence of rheumatoid diseases did not show any significance in increased risk of DR. HCQ prescription can improve systemic glycemic profile, but it does not decrease the risk of diabetic ophthalmic complications.

Abstract Purpose To compare the outcomes of patients with AMI underwent percutaneous coronary intervention (PCI) complicated by cardiogenic shock treated with IABP vs MLVAD. Methods The Nationwide Inpatient Sample (NIS) database is the largest inpatient registry in the U.S. We used NIS year 2009–2014 to identify adult patients admitted for AMI, who received PCI and complicated by cardiogenic shock. Based on the use of IABP or MLVAD, the study population was divided into 2 groups. To reduce selection bias, we performed propensity score matching using Kernell method. Patient characteristics, hospital characteristics, and comorbidities were matched. Logistic regression was used for categorical variables including in-hospital mortality, requirement of blood transfusion, sepsis, cardiac arrest and cardiac complications (including iatrogenic complications, hemopericardium, and cardiac tamponade). Poisson regression was used for continuous variables including length of stay and total cost. Results A total of 49837 patients were identified. With propensity score match, 34132 patients in IABP group were matched to 1430 patients in MLVAD group. Compared with MLVAD group, the IABP group had lower in-hospital mortality rates (28.29% vs 40.36%, OR 0.58 (0.42–0.81), p=0.002), lower rate of blood transfusion (9.63% vs 11.50%, OR 0.49 (0.27–0.88), p=0.017), and lower cost (47167 vs 70429 USD, p&lt;0.001). IABP and MLVAD group had similar length of stay (8.9 versus 9.3 days, p=0.882), rates of cardiac complication (6.50% vs 7.24%, OR 0.56 (0.26–1.19), p=0.134), rates of sepsis (9.30% vs 14.98%, OR 0.66 (0.38–1.14), p=0.133), and rates of cardiac arrest (37.84% vs 41.05%, OR 0.70 (0.45–1.10), p=0.123). Conclusion In patients with AMI underwent PCI and complicated by cardiogenic shock, MLAVD compared with IABP was associated with higher risk of in-hospital mortality, requirement of blood transfusion indicating presence of major bleeding complications, and cost, although study interpretation is limited by retrospective observational design. Further research is warranted to elucidate the optimal MCSD in these patients. Funding Acknowledgement Type of funding source: None

Abstract Background Neurocysticercosis is a Neglected Tropical Disease and an important public health issue. Our goal was to collect and analyze data regarding clinically significant gender differences among our Neurocysticercosis patients. Methods A retrospective chart search with ICD 9/ ICD 10 diagnostic code for Neurocysticercosis and neuroimaging suggestive of Neurocysticercosis was performed for clinical encounters in the hospital or affiliated clinics between years 2013–2018. After a careful chart review, patients who were clinically diagnosed with Neurocysticercosis were included in the study. T-test was used to compare means of continuous variables and chi-square test to compare proportions of categorical variables. Results Among 90 total patients included, male (49.4%) and female (50.6%) distribution were nearly identical. The mean age in females was found to be higher than males (52.5 vs 42.0, P &lt; 0.0001). Almost an equal number of males and females presented with either seizures (63.6% vs 57.8%, P= 0.85), headaches (25.0% vs 28.9%, p= 0.85), or other symptoms (11.4% vs 13.3%, p= 0.85). Males had more generalized seizures compared to females (60% vs 38%, P= 0.37), although this result was not statistically significant. Females were more likely to present with &gt; 1 lesion (82.2% vs 56.8%, P= 0.01). Males were more likely to have cystic lesions (64.7% vs 27.9%, P &lt; 0.001) compared to females who had more calcified lesions on presentation (65.1% vs 20.6%, P &lt; 0.001). Male patients were more likely to have contrast enhancement or edema surrounding the lesions (61.4% vs 33.3%, P= 0.01) and were more likely to require treatment with Albendazole/Praziquantel (75.8% vs 31.7%, P &lt; 0.001). Conclusion Although previously reported data is limited, there is a suggestion that there are gender differences in host immune response and that inflammation surrounding parenchymal lesions is more intense in females. This study suggests that men either present early in the disease phase or have different immune responses than women and require anti-parasitic therapy more frequently. More research in this aspect is needed. Disclosures All Authors: No reported disclosures
