BackgroundThe HEART Pathway combines a History ECG Age Risk factor (HEAR) score and serial troponins to risk stratify patients with acute chest pain. However, it is unclear whether patients with HEAR scores of <1 require troponin testing. The objective of this study is to measure the major adverse cardiac event (MACE) rate among patients with <1 HEAR scores and determine whether serial troponin testing is needed to achieve a miss rate <1%.MethodsA secondary analysis of the HEART Pathway Implementation Study was conducted. HEART Pathway risk assessments (HEAR scores and serial troponin testing at 0 and 3 hours) were completed by the providers on adult patients with chest pain from three US sites between November 2014 and January 2016. MACE (composite of death, myocardial infarction (MI) and coronary revascularisation) at 30 days was determined. The proportion of patients with HEAR scores of <1 diagnosed with MACE within 30 days was calculated. The impact of troponin testing on patients with HEAR scores of <1 was determined using Net Reclassification Improvement Index (NRI).ResultsProviders completed HEAR assessments on 4979 patients and HEAR scores<1 occurred in 9.0% (447/4979) of patients. Among these patients, MACE at 30 days occurred in 0.9% (4/447; 95% CI 0.2% to 2.3%) with two deaths, two MIs and 0 revascularisations. The sensitivity and negative predictive value for MACE in the HEAR <1 was 97.8% (95%CI 94.5% to 99.4%) and 99.1% (95% CI 97.7% to 99.8%), respectively, and were not improved by troponin testing. Troponin testing in patients with HEAR <1 correctly reclassified two patients diagnosed with MACE, and was elevated among seven patients without MACE yielding an NRI of 0.9% (95%CI −0.7 to 2.4%).ConclusionThese data suggest that patients with HEAR scores of 0 and 1 represent a very low-risk group that may not require troponin testing to achieve a missed MACE rate <1%.Trial registration numberNCT02056964

Introduction: We sought to (1) classify patients who underwent stress echocardiography in an emergency department observation unit based on their pretest probabilities of obstructive CAD using the Diamond-Forrester criterion, (2) to compare observed versus expected frequencies of obstructive CAD based on the Diamond-Forrester risk categories of low (<25%), intermediate (25-75%), and high (>75%) pretest probability of disease, and (3) to test the association of traditional cardiovascular risk factors (age, gender, hypertension, diabetes, high cholesterol, and smoking) with obstructive CAD. METHODS: Retrospective review of the electronic medical record for patients who presented to the emergency department with chest pain and underwent observation followed by stress echocardiography between the period January 1, 2012 to December 31, 2012. Patients were classified as low, intermediate, or high risk for obstructive CAD using the Diamond-Forrester criterion. Main outcome measures were stress echocardiography results as well as receipt of cardiac catheterization and results. RESULTS: A total of 504 patients were included in the final analysis. Overall, 4.8% had a positive stress test and only 1.2% had angiographic evidence of obstructive CAD. In each category of risk, the observed frequency of obstructive CAD was significantly lower than expected. Having a high pretest probability as defined by the Diamond-Forrester criterion was significantly associated with obstructive CAD. Age, gender, diabetes, hypertension, high cholesterol, and smoking were not independently associated with evidence of obstructive CAD; nor were any composites of these risk factors. CONCLUSIONS: The traditional Diamond-Forrester criterion significantly overestimates the probability of obstructive CAD in ED observation unit patients. Reliance on the Diamond-Forrester criterion and other traditional risk factors associated with obstructive CAD in the outpatient setting could lead to faulty Bayesian reasoning, overuse of non-invasive imaging, and improper interpretation of test results in an ED population of low-risk chest pain patients. Further work is required to determine an optimal risk-assessment strategy for this patient population.

IntroductionPatients presenting to EDs with chest pain of possible cardiac origin represent a substantial and challenging cohort to risk stratify. Scores such as HE-MACS (History and Electrocardiogram-only Manchester Acute Coronary Syndromes decision aid) and HEAR (History, ECG, Age, Risk factors) have been developed to stratify risk without the need for troponin testing. Validation of these scores remains limited.MethodsWe performed a post hoc analysis of the Limit of Detection and ECG discharge strategy randomised-controlled trial dataset (n=629; June 2018 to March 2019; 8 UK hospitals) to calculate HEAR and HE-MACS scores. A <4% risk of major adverse cardiac events (MACE) at 30 days using HE-MACS and a score of <2 calculated using HEAR defined ‘very low risk’ patients suitable for discharge. The primary outcome of MACE at 30 days was used to assess diagnostic accuracy.ResultsMACE within 30 days occurred in 42/629 (7%) of the cohort. HE-MACS and HEAR scores identified 85/629 and 181/629 patients as ‘very low risk’, with MACE occurring in 0/85 and 1/181 patients, respectively. The sensitivities of each score for ruling out MACE were 100% (95% CI: 91.6% to 100%) for HE-MACS and 97.6% (95% CI: 87.7% to 99.9%) for HEAR. Presenting symptoms within these scores were poorly predictive, with only diaphoresis reaching statistical significance (OR: 4.99 (2.33 to 10.67)). Conventional cardiovascular risk factors and clinician suspicion were related to the presence of MACE at 30 days.ConclusionHEAR and HE-MACS show potential as rule out tools for acute myocardial infarction without the need for troponin testing. However, prospective studies are required to further validate these scores.

BackgroundThe majority of patients presenting to the ED with cardiac sounding chest pain have a non-diagnostic ECG and the problem of differentiating those suffering an acute coronary syndrome from those without is familiar to all ED clinical staff. To stratify risk in these patients, specific scores have been developed. Recent work has focused on incorporating newer high-sensitivity cardiac troponin (hs-cTn) assays; however, issues regarding performance and availability of these assays remain.AimProspectively compare HEART, Global Registry of Acute Coronary Events (GRACE) and Thrombolysis in Myocardial Infarction (TIMI) scores, using a single contemporary cTn at admission, to predict a major adverse cardiac event (MACE) at 30 days.MethodProspective observational cohort study performed in a UK tertiary hospital in patients with suspected cardiac chest pain and no significant ST elevation on initial ECG. Data collection took place 2 December 2014 to 8 February 2016. The treating clinician recorded risk score data real time and a single contemporary cTn taken at presentation was used in score calculation. The primary endpoint was 30-day MACE. C-statistic was determined for each score and diagnostic characteristics of high-risk and low-risk cut-offs were calculated.Results189/1000 patients in the study developed a 30-day MACE. The c-statistic of HEART for 30-day MACE (0.87 (95% CI 0.84 to 0.90)) was higher than TIMI (0.78 (95% CI 0.74 to 0.81)) and GRACE (0.74 (95% CI 0.70 to 0.78)).HEART score ≤3 identified low-risk patients with sensitivity 99.5% (95% CI 97.1% to 99.9%) and negative predictive value (NPV) 99.6% (95% CI 97.3% to 99.9%) exceeding TIMI 0 (sensitivity 97.4% (95% CI 93.9% to 99.1%) and NPV 97.8% (95% CI 94.8% to 99.1%)) and GRACE score 0–55 (sensitivity 95.2% (95% CI 91.1% to 97.8%) and NPV 95.8% (95% CI 92.2% to 97.7%)).ConclusionHEART outperformed both TIMI and GRACE in overall discriminative capacity for 30-day MACE. Using a single contemporary cTn at presentation, a HEART score of ≤3 demonstrated sensitivity and NPV of ≥99.5% for 30-day MACE. These results reach the threshold for a safe discharge strategy but should be interpreted thoughtfully in light of other work.

262 Background: Patients receiving chemotherapy are at risk for febrile neutropenia following treatment. The American Society of Clinical Oncology (ASCO) and National Comprehensive Cancer Network (NCCN) recommend screening patients for risk of febrile neutropenia and risk stratification based on likelihood of febrile neutropenia events. Prophylactic growth factors (G-CSF) should be in patients receiving high-risk regimens or intermediate-risk regimens with individual risk factors. The impact of electronic medical record system (EMR) implementation on compliance with G-CSF support guidelines has not been studied. Methods: At West Virginia University/Mary Babb Randolph Cancer Center we conducted an IRB approved retrospective chart review of cancer patients receiving chemotherapy from January 1, 2007 to August 1, 2008 (pre-EMR) and January 1, 2011 to December 31, 2011 (post-EMR). We reviewed the chemotherapy regimens and patient risk factors for developing febrile neutropenia, and determined if the G-CSF usage was consistent with guideline recommendations. Results: Compliance with prophylactic G-CSF guidelines was 75.6% in the post-EMR arm, compared to 67.5% in the pre-EMR arm (p=0.041, ch-square). The post EMR data of 1,042 new chemotherapy initiations showed: (see Table). The appropriateness of usage in high and low risk patients were the most compliant, as G-CSF orders were built into chemotherapy plans of high risk regimens and omitted from low risk regimens. Conclusions: Appropriate prophylactic G-CSF usage can be improved when orders are integrated into standard chemotherapy order sets in an EMR. An area of further improvement would include automatic identification of individual risk factors by the EMR. [Table: see text]
