AbstractThe optimal vascular access type for elderly hemodialysis patients is controversial. We evaluated the impact of comorbidity burden on the association between vascular access type and mortality risk among 23,100 hemodialysis patients aged ≥65 years from the Korean Society of Nephrology End-Stage Renal Disease registry data. Subjects were stratified into tertiles according to the simplified Charlson comorbidity index (sCCI), and the survival and hospitalization rates were compared with respect to vascular access type: arteriovenous fistula (AVF), arteriovenous graft (AVG), and central venous catheter (CVC). Among all tertiles of sCCI, CVC use showed highest risk of mortality than AVF use. In the lowest to middle tertile, no difference was observed in survival rates between the use of AVF and AVG. However, in the highest tertile, AVG use showed higher risk of mortality than AVF use. When subjects were classified according to a combination of sCCI tertile and access type (AVF vs. AVG), patients with the highest CCI with AVG showed 1.75-folded increased risk of mortality than those with the lowest sCCI with AVF. Hospitalization rates due to access malfunction were highest in patients with CVC in all sCCI tertiles. In the highest tertile, patients with AVG showed increased rates of hospitalization compared to those with AVF due to access malfunction. However, hospitalization rates due to access infection were highest in patients with AVG in all tertiles. The use of AVF may be of benefit and switching to AVF should be considered in elderly hemodialysis patients with a high burden of comorbidity.

Background: More data are needed about the safety of antibiotic de-escalation in specific clinical situations as a strategy to reduce exposure to broad-spectrum antibiotics. This study aims to compare the survival curve of patient de-escalated (early or late) against those not de-escalated on antibiotics, to determine the association of patient related, clinical related, and pressure sore/device related characteristics on all-cause 30-day mortality and determine the impact of early and late antibiotic de-escalation on 30-day all-cause mortality. Methods: This is a retrospective cohort study on patients in medical ward Hospital Kuala Lumpur, admitted between January 2016 and June 2019. A Kaplan–Meier survival curve and Fleming–Harrington test were used to compare the overall survival rates between early, late, and those not de-escalated on antibiotics while multivariable Cox proportional hazards regression was used to determine prognostic factors associated with mortality and the impact of de-escalation on 30-day all-cause mortality. Results: Overall mortality rates were not significantly different when patients were not de-escalated on extended or restricted antibiotics, compared to those de-escalated early or later (p = 0.760). Variables associated with 30-day all-cause mortality were a Sequential Organ Function Assessment (SOFA) score on the day of antimicrobial stewardship (AMS) intervention and Charlson’s comorbidity score (CCS). After controlling for confounders, early and late antibiotics were not associated with an increased risk of mortality. Conclusion: The results of this study reinforce that restricted or extended antibiotic de-escalation in patients does not significantly affect 30-day all-cause mortality compared to continuation with extended and restricted antibiotics.

First Choice

Current international guidelines advocate fistula creation as first choice for vascular access in haemodialysis patients, however, there have been suggestions that in certain groups of patients, in particular the elderly, a more tailored approach is needed. The prevalence of more senior individuals receiving renal replacement therapy has increased in recent years and therefore including patient age in decision making regarding choice of vascular access for dialysis has gained more relevance. However, it seems that age is being used as a surrogate for overall clinical condition and it can be proposed that frailty may be a better basis to considering when advising and counselling patients with regard to vascular access for dialysis. Frailty is a clinical condition in which the person is in a vulnerable state with reduced functional capacity and has a higher risk of adverse health outcomes when exposed to stress inducing events. Prevalence of frailty increases with age and has been associated with an increased risk of mortality, hospitalisation, disability and falls. Chronic kidney disease is associated with premature ageing and therefore patients with kidney disease are prone to be frailer irrespective of age and the risk increases further with declining kidney function. Limited data exists on the relationship between frailty and vascular access, but it appears that frailty may have an association with poorer outcomes from vascular access. However, further research is warranted. Due to complexity in decision making in dialysis access, frailty assessment could be a key element in providing patient-centred approach in planning and maintaining vascular access for dialysis.

The Impact

An increased interest regarding the impact of frailty on the prognosis of cardiovascular disease (CVD) has been observed in the last decade. Frailty is a syndrome characterized by a reduced biological reserve that increases the vulnerability of an individual in relation to stressors. Among the patients with CVD, a higher incidence of frailty has been reported in those with heart failure (HF). Regardless of its conceptualizations, frailty is generally associated with negative outcomes in HF and an increased risk of mortality. Psychological factors, such as depression and anxiety, increase the risk of negative outcomes on the cardiac function and mortality. Depression and anxiety are found to be common factors impacting the heart disease and quality of life (QoL) in patients with HF. Depression is considered an independent risk factor of cardiac-related incidents and death, and a strong predictor of rehospitalization. Anxiety seems to be an adequate predictor only in conjunction with depression. The relationship between psychological factors (depression and anxiety) and frailty in HF has hardly been documented. The aim of this paper is to review the reported data from relevant studies regarding the impact of depression and anxiety, and their effects on clinical outcomes and prognosis in frail patients with HF.

180 Background: Current guidelines recommend six months of chemotherapy (CT) for stage III colon cancer and consideration for high-risk stage II colon cancer. No previous studies have examined the impact of CT gaps on survival. This retrospective study examines determinants of CT gaps and the effect of gaps on survival. Methods: Using national Surveillance, Epidemiology, and End Results registry-Medicare linked data, high-risk stage II and stage III colon cancer patients diagnosed between 2000-2007 who received surgery and CT were identified. CT duration and gaps were calculated. CT gap was defined as 30 to 90 days between two CT claims. Data on demographics, clinical factors (comorbidity, tumor grade), and treatment factors (time to CT initiation, toxicity, hospitalization) were collected. Multivariable regression was used to examine factors associated with gaps. Cox proportional hazards analysis examined the effect of gaps on risk of mortality. Results: 7,371 patients were identified. Median age was 75 (IQR: 71-79); 47% were male. Among all patients, 1,803 (24%) had a gap. 2,674 patients (36%) received 5 to 7 months of CT, of which 469 (18%) had a gap. Multivariable regression analysis showed that patients who were black (OR 1.3, 95% CI: 1.1-1.7), stage III (1.2, 1.0-1.3), had toxicity (1.3, 1.1-1.4), or had 3 to 4 months of CT (vs. 5-7 months, 2.6, 2.3-3.0) were more likely to have a gap, while patients with a more recent diagnosis in 2007(vs. 2000, 0.6, 0.5-0.8) were less likely to have a gap. 3-year cancer-specific survival was the same in all patients with CT gaps compared with no gaps (80%, 95% CI: 78%-82% vs. 81%, 95% CI: 80%-82%). Cox proportional hazard models showed that patients with gaps did not have increased risk of mortality (HR 0.99, 0.89-1.1) adjusting for patient and clinical factors. Among those who received 5 to 7 months of CT, 3-year survival was 8% lower in patients with gaps compared to those with no gaps (80%, 95% CI: 75%-83% vs. 88%, 95% CI: 87%-90%). Conclusions: Nearly 25% of high-risk stage II and III patients who received CT had a gap. CT gaps were associated with worse survival in patients who received 5 to 7 months of CT. Interventions to improve CT toxicity management and reduce gaps are needed to maximize the benefit of CT.

510 Background: In treatment of rectal adenocarcinoma, an increased time delay (TD) of 6-12 weeks from the end of radiation therapy to surgery may increase the rate of complete pathologic response (pCR), but the optimal TD with respect to survival has not been established. This study evaluates the impact of TD on overall mortality. Methods: The NCDB was queried for patients with adenocarcinoma of the rectum and no evidence of metastasis at diagnosis, who underwent preoperative chemoradiation followed by radical surgical resection. Standard statistical methods were employed for descriptive statistics and Cox model development. Results: The study included 6805 patients, predominantly Caucasian (87.2%) and males (63.9%) who generally were treated with low anterior resection (57.3%), colonanal reanastomosis (8.4%), or abdominoperineal resection (28.4%), and had median survival of 66.6 months. The effects of age, surgical margins (-/+), comorbidity index, time to discharge after surgery, TMN pathologic staging, surgical volume, and patient income significantly impacted mortality after radiation and surgery (p<0.05 for all values). There was a significant relationship between TD and pCR (p=.0002). At TD less than 30 days, 4.0% of patients achieved pCR, while 9.3% of patients have achieved pCR by 75 days. In TD of greater than 75 days, the rate of pCR decreased. Overall, 6.8% of patients (n=461) achieved pCR. Using a refined cox model, a TD of more than 60 days was associated with 20% greater risk of mortality (95% CI 1.068 – 1.367). This effect became more pronounced with increasing TD; a TD of greater than 75 days was associated with 28% (95% CI 1.06-1.55) increased risk of mortality, while patients with TD less than 60 days saw a survival benefit. Conclusions: Though an interval up to 75 days between radiation and surgery may achieve higher rates of complete pathologic response, delay of more than 60 days from radiation to surgical resection and subsequent systemic chemotherapy decreases overall survival in patients with rectal cancer.

Abstract Background: Racial disparities in outcomes of cancer patients have been reported. Access to comprehensive cancer centers is associated with improved overall survival (OS) but racial/ethnic minorities may have a disparate access to such care. While the impact of treatment facility volume on outcomes has been evaluated, outcomes of centers with minority-predominant patient population have not been studied. We compared demographic profiles, facility level data and OS of patients treated at minority-predominant facilities to facilities that treated predominantly non-Hispanic Whites (NHW) with non-DLBCL. Methods: The National Cancer Database (NCDB) was used to identify all non-DLBCL patients diagnosed between 2004 and 2015. "Minority-treating facilities" were defined as facilities in the top decile by proportion for initial treatment of non-Hispanic African-Americans (NHAA), Hispanics and other races. We performed univariate and multivariate analyses to compare sociodemographic and clinical factors influencing outcomes between minority treating and non-minority treating facilities. A subgroup analysis stratified by race/ethnicity was also conducted to study the effect of treating facilities on the outcome of NHWs and minorities separately. Results: Of 1339 total facilities, 123 (9.1%) qualified as minority treating. Of 207,239 eligible patients in NCDB, 18,719 (9.03%) received treatment at the minority-treating facilities and of these, 11,190 (~60%) belonged to the minority races. Overall, 4.5% (6,988/156,664) NHWs and 30% (11,190/37,639) minorities received treatment at the minority-treating facilities. Several demographic and facility level characteristics were significantly different among the patients treated at minority-treating facilities as compared to non-minority treating facilities. Overall, significantly higher number of patients in minority-treating hospitals had lower income and education, had Medicaid coverage or lack of insurance. The OS of patients in minority treating facilities was significantly worse as compared to non-minority facilities (Figures). On multivariate analysis, patients who received treatment at minority-treating facilities were at 10% (HR=1.10, 95% CI: 1.06-1.14 p<0.001) higher risk of mortality as compared to those treated at the non-minority treating facilities. On multivariate analysis, NHAA (30% increased risk) and 'other races' (9% increased risk) were at significantly higher risk of mortality as compared to the NHW (Table 2). To study the effect of treatment at minority-treating facilities on OS among the patients of same race/ethnicity group, a multivariate analysis was also run separately for NHW and racial minorities. The NHWs who received treatment at minority-treating facilities were at 13% higher risk of death (HR=1.13, 95% CI: 1.08-1.19 p<0.001) as compared to NHWs who were treated at non-minority treating facilities. Similarly, the racial minorities who received treatment at minority treating facilities were at 8% higher risk of death (HR=1.08, 95% CI: 1.03-1.19 p=0.003) as compared to those who received treatment at the nonminority treating facilities. Conclusions:Outcomes of patients who received treatment at minority treating facilities was significantly worse than those at non-minority treating facilities. This was true for NHWs and racial minorities separately as well. Several demographic and facility level characteristics were significantly different in the two groups however OS remained worse after adjusting for them. Causes of poor outcomes at minority-treating facilities must be analyzed to mitigate them and improve outcomes for all. Figure. Figure.

Abstract Background Data in the literature about HSV reactivation in COVID-19 patients are scarce, and the association between HSV-1 reactivation and mortality remains to be determined. Our objectives were to evaluate the impact of Herpes simplex virus (HSV) reactivation in patients with severe SARS-CoV-2 infections primarily on mortality, and secondarily on hospital-acquired pneumonia/ventilator-associated pneumonia (HAP/VAP) and intensive care unit-bloodstream infection (ICU-BSI). Methods We conducted an observational study using prospectively collected data and HSV-1 blood and respiratory samples from all critically ill COVID-19 patients in a large reference center who underwent HSV tests. Using multivariable Cox and cause-specific (cs) models, we investigated the association between HSV reactivation and mortality or healthcare-associated infections. Results Of the 153 COVID-19 patients admitted for ≥ 48 h from Feb-2020 to Feb-2021, 40/153 (26.1%) patients had confirmed HSV-1 reactivation (19/61 (31.1%) with HSV-positive respiratory samples, and 36/146 (24.7%) with HSV-positive blood samples. Day-60 mortality was higher in patients with HSV-1 reactivation (57.5%) versus without (33.6%, p = 0.001). After adjustment for mortality risk factors, HSV-1 reactivation was associated with an increased mortality risk (hazard risk [HR] 2.05; 95% CI 1.16–3.62; p = 0.01). HAP/VAP occurred in 67/153 (43.8%) and ICU-BSI in 42/153 (27.5%) patients. In patients with HSV-1 reactivation, multivariable cause-specific models showed an increased risk of HAP/VAP (csHR 2.38, 95% CI 1.06–5.39, p = 0.037), but not of ICU-BSI. Conclusions HSV-1 reactivation in critically ill COVID-19 patients was associated with an increased risk of day-60 mortality and HAP/VAP.

Background: Pre-end stage renal disease (ESRD) Kidney Disease Education (KDE) has been shown to improve multiple chronic kidney disease (CKD) outcomes but, its impact on vascular access outcomes is not well-studied. In 2010, Medicare launched KDE reimbursements policy for patients with advanced CKD. Methods: In this retrospective USRDS analysis, we identified all adult incident hemodialysis patients with a minimum of 6-months of pre-ESRD Medicare coverage during the first five-years of CMS-KDE policy and divided them into CMS-KDE services recipients (KDE-cohort) and non-recipients (non-KDE cohort). The primary outcome was incident arteriovenous fistula (AVF) and the composite of incident AVF or arteriovenous graft (AVG) utilization. Secondary outcomes were central venous catheter (CVC) with maturing AVF/AVG and pure CVC utilizations. Step-wise multivariate analyses were performed in four progressive models (model 1: KDE alone, model 2: multivariate model encompassing model 1 with socio-demographics, model 3: model 2 with comorbidity and functional status, and model 4: model 3 with pre-ESRD nephrology care). Results: Of the 211,990 qualifying incident hemodialysis patients during the study period, 2,887(1.4%) received KDE services before dialysis initiation. The rates of incident AVF and composite AVF/AVG were more than double (29.7% and 34.9% respectively, compared to 14.2% and 17.2%) and pure catheter use about a third lower (40.4% compared to 64.5%) in the KDE cohort compared to the non-KDE cohort. Maximally adjusted odds ratio(99% confidence interval) in model 4 for study outcomes were: incident AVF use: 1.78 (1.55-2.05), incident AVF/AVG use: 1.78 (1.56-2.03), incident CVC with maturing AVF/AVG: 1.69 (1.44-1.97)and pure CVC without any AVF/AVG: 0.51 (0.45-0.58). The benefits of KDE service were maintained even after accounting for the presence, duration and facility of ESRD care. Conclusion: Occurrence of pre-ESRD KDE service is associated with significantly improved incident vascular access outcomes. Targeted studies are needed to examine the impact of KDE on patient engagement and self-efficacy as a cause for improvement in vascular access outcomes.

The impact of the coronavirus disease 2019 (COVID-19) pandemic on health-care quality in the emergency department (ED) in countries with a low risk is unclear. This study aimed to explore the effects of the COVID-19 pandemic on ED loading, quality of care, and patient prognosis. Data were retrospectively collected from 1 January 2018 to 30 September 2020 at the ED of Tri-service general hospital. Analyses included day-based ED loading, quality of care, and patient prognosis. Data on triage assessment, physiological states, disease history, and results of laboratory tests were collected and analyzed. The number of daily visits significantly decreased after the pandemic, leading to a reduction in the time to examination. Admitted patients benefitted from the pandemic with a reduction of 0.80 h in the length of stay in the ED, faster discharge without death, and reduced re-admission. However, non-admitted visits with chest pain increased the risk of mortality after the pandemic. In conclusion, the COVID-19 pandemic led to a significant reduction in low-acuity ED visits and improved prognoses for hospitalized patients. However, clinicians should be alert about patients with chest pain due to their increased risk of mortality in subsequent admission.
