Abstract Background Opioid dependence and overdose are at epidemic levels in the United States. Ohio has the third highest rate of opioid-related overdose deaths. Infectious complications of intravenous drug use (IDU) include increased acquisition of hepatitis C, HIV and infective endocarditis. In this study, we aimed to characterize cases of infective endocarditis admitted to our healthcare system over a five-year period. We additionally sought to determine the validity of using ICD codes to identify infective endocarditis cases and IDU. Methods Patients with ICD-9 or 10 discharge diagnosis codes for infective endocarditis were identified from our institution’s electronic health record. ICD codes pertaining to substance abuse were used to classify patients according to IDU status. Readmissions during the same episode of infective endocarditis were excluded. We compared chart review to ICD code for the identification of infective endocarditis and IDU in a random sample of 296 of 1590 cases. Results Of 296 charts reviewed, 133 (44.9%) were excluded because they did not meet criteria for definite infective endocarditis by modified Duke’s criteria or because the episode was a readmission. A total of 163 (55.1%) cases met inclusion criteria, all of whom were seen in consultation by the inpatient Infectious Disease service. Of these, 52 (31.9%) had ICD 9 or 10 codes linked to substance abuse. Following manual chart review, we established that in fact 86 of these 163 cases (52.8%) had evidence of substance abuse. Conclusion Misclassification due to use of ICD codes is a well-established challenge to epidemiological research. However, the extent of misclassification in this analysis was greater than expected. If prior research on IDU and infective endocarditis has relied on medical record data alone without verification through manual chart review, the observed epidemiological trends may not be accurate.

Abstract Objective To evaluate the phenotyping performance of three major electronic health record (EHR) components: International Classification of Disease (ICD) diagnosis codes, primary notes, and specific medications. Materials and Methods We conducted the evaluation using de-identified Vanderbilt EHR data. We preselected ten diseases: atrial fibrillation, Alzheimer’s disease, breast cancer, gout, human immunodeficiency virus infection, multiple sclerosis, Parkinson’s disease, rheumatoid arthritis, and types 1 and 2 diabetes mellitus. For each disease, patients were classified into seven categories based on the presence of evidence in diagnosis codes, primary notes, and specific medications. Twenty-five patients per disease category (a total number of 175 patients for each disease, 1750 patients for all ten diseases) were randomly selected for manual chart review. Review results were used to estimate the positive predictive value (PPV), sensitivity, and F -score for each EHR component alone and in combination. Results The PPVs of single components were inconsistent and inadequate for accurately phenotyping (0.06–0.71). Using two or more ICD codes improved the average PPV to 0.84. We observed a more stable and higher accuracy when using at least two components (mean ± standard deviation: 0.91 ± 0.08). Primary notes offered the best sensitivity (0.77). The sensitivity of ICD codes was 0.67. Again, two or more components provided a reasonably high and stable sensitivity (0.59 ± 0.16). Overall, the best performance ( F score: 0.70 ± 0.12) was achieved by using two or more components. Although the overall performance of using ICD codes (0.67 ± 0.14) was only slightly lower than using two or more components, its PPV (0.71 ± 0.13) is substantially worse (0.91 ± 0.08). Conclusion Multiple EHR components provide a more consistent and higher performance than a single one for the selected phenotypes. We suggest considering multiple EHR components for future phenotyping design in order to obtain an ideal result.

Background: Infective endocarditis (IE) affects up to 20,000 people per year in the United States. Stroke is a feared complication of IE and is associated with high morbidity and mortality. We aim to identify predictors of stroke in a large sample of patients treated at a tertiary care center. Methods: A retrospective chart review was carried out using ICD9 codes for IE and cerebrovascular events in patients admitted to the New York Presbyterian Hospital/Columbia University Medical Center from 2000 to 2015. Incident stroke was ascertained if imaging demonstrated an acute infarction during the hospital visit in which endocarditis was diagnosed using Duke’s criteria. Demographics, vascular risks and ancillary data were obtained by chart review. Generalized linear models were used to obtain the risk ratio (RR) and their 95% confidence intervals (95%CI) adjusting for age, sex, ethnicity, hypertension, diabetes, dyslipidemia, smoking, congestive heart failure (CHF), presence of cardiac vegetations, valvular abscesses, positive blood culture, and immunosuppression. Results: The sample included 727 IE subjects (mean age 61±18, range 18-101, 62% men, 62% non-white). Twelve percent of the sample were immunosuppressed. The majority of the patient had vegetations (61%) and positive blood cultures (87%, MRSA 13%) while valvular abscess were less frequent (13%). Of the 727 patients, 13% had an acute pre-surgical stroke (10% ischemic and 3% hemorrhagic). Meanwhile, of the 314 patient who underwent surgical intervention, only 0.5% had post-surgical strokes. The risk of pre-operative ischemic stroke was higher among patients with diabetes (RR 1.7, 1.1-2.8), cardiac vegetations (RR 2.8, 1.6-5.0), and history of prior stroke (RR 1.8, 1.8-2.9) while the risk of pre-surgical hemorrhagic stroke was higher among patients with history of prior stroke (RR 4.5, 1.7-11.9). Conclusions: Prior stroke was a risk factor for ischemic and hemorrhagic stroke, which suggests baseline brain vulnerability that may influence the risk of stroke in the setting of IE. Additionally, diabetes and the presence of vegetations increased the risk of ischemic stroke. Early identification of sub-populations with IE at risk of stroke may help stratify risk and test preventive interventions.

Abstract Objectives This study aimed to compare comorbidities and biologic DMARD (bDMARD) use between AS and non-radiographic axial SpA (nr-axSpA) patients, using a large cohort of patients from routine clinical practice in the United States. Methods We performed a cross-sectional study using electronic medical records from two academic hospitals in the United States. Data were extracted using automated searches (⩾3 ICD codes combined with text searches) and supplemented with manual chart review. Patients were categorized into AS or nr-axSpA according to classification criteria. Disease features, comorbidities (from a list of 39 chronic conditions) and history of bDMARD prescription were compared using descriptive statistics. Results Among 965 patients identified, 775 (80%) were classified as having axSpA. The cohort was predominantly male (74%) with a mean age of 52.5 years (s.d. 16.8). AS patients were significantly older (54 vs 46 years), more frequently male (77% vs 64%) and had higher serum inflammatory markers than those with nr-axSpA (median CRP 3.4 vs 2.2 mg/dl). Half of all patients had at least one comorbidity. The mean number of comorbidities was 1.5 (s.d. 2.2) and similar between AS and nr-axSpA groups. A history of bDMARD-use was seen in 55% of patients with no difference between groups. The most commonly prescribed bDMARDs were adalimumab (31%) and etanercept (29%). Ever-prescriptions of individual bDMARDs were similar between AS and nr-axSpA. Conclusion Despite age differences, nr-axSpA patients had similar comorbidity burdens as those with AS. Both groups received comparable bDMARD treatment in this United States clinic-based cohort.

Objective: As the opioid addiction epidemic continues to grow, other serious health issues regarding drug use has also increased. This study examines the trends in admissions and population characteristics of those who experience infective endocarditis with opioid drug dependence.Methods: We used ICD-9-CM and ICD-10-CM codes to identify patients admitted to a hospital with infective endocarditis and with a secondary diagnosis of opioid use related disorders using data released by the Florida Agency for Health Care Administration (AHCA). Data included age, gender, ethnicity, race, discharge disposition, admission type, payer status, total charges, and zip code of patients’ residence.Results: During the four-year period, the percent of patients diagnosed with infective endocarditis and a diagnosis code associated with opioid abuse or dependence doubled (4.48% to 8.52%). Of the patients dually diagnosed, the mean age was 37.47 and the majority were white (90.78%), non-Hispanic (91.96%), and female (58.55%). Nearly 47% of the patients did not have health insurance. The percentage of patients with both diagnosis codes living in urban counties was 91.37%. Median length of stay was 10 days and median total charges for patients was $101,604.Conclusions: With the increasing incidence of opioid dependence and addiction within the United States, there is a rise in infective endocarditis, a costly and debilitating disease. Our analysis provides the framework for hospital systems to identify patients who may benefit from addiction services, which through downstream effects will cause less of a health and financial burden.

Abstract Background In many areas of the United States, substance use disorders (SUD) have increased dramatically over the past decade. Overdose deaths have increased as well, and Kentucky ranks among the nation’s leaders in deaths per 100,000 population. Infective endocarditis (IE) is a well-known complication of intravenous drug use, contributing to significant morbidity and mortality, but few studies have evaluated the effect of the current SUD epidemic on rates and demographics of IE. We sought to examine the trends in IE and IE with SUD at our institution. Methods We collected data from patients admitted to a large academic medical center in Kentucky between January 1, 2013 and December 31, 2016. Patients were classified according to the International Classification of Diseases, Tenth Revision. Patients were considered to have IE if they received codes I33 or I38. Patients were considered to have an SUD if they received codes F11.10, F15.10, F14.10, F19.10, or Z86.59. Data were collected through the TriNetX database (TriNetX, Cambridge, MA). Results There were 2,100 cases of IE during the study period. The mean (SD) age was 53 years (21). Of those, 440 also had an SUD. The mean (SD) age of these patients was 41 years (11). Patients in both the IE and IE/SUD categories were primarily male (54% and 55%) and white (94% and 94%). The number of cases of IE increased from 190 in 2013 to 430 in 2016 (R2 = 0.9877). The number of IE cases diagnosed as having an SUD increased from 30 (16% of all IE cases) in 2013 to 130 (30% of all IE cases) in 2016 (R2 = 0.7352 for the trend). This increase in cases corresponds to a 333% increase in the number of cases of IE with SUD. Conclusion Between 2014 and 2016, opioid overdose deaths in Kentucky rose from 24.7 to 33.5 per 100,000 population, a 35.6% increase. During a similar timeframe, the number of IE cases associated with SUD at our institution rose 333%. While it is possible that increased coding of substance use disorders factored into this dramatic increase, it appears that the number of IE cases associated with SUD is rising at a disproportionately rapid rate.

Substance abuse is a major medical and social problem. Estimates suggest that each year some 15 percent of the 4 million babies born in the United States are exposed to drugs or alcohol. Research demonstrates that exposure to these substances is harmful to the children in both the short term and across their developmental trajectory. This chapter summarizes the harms that might result from such prenatal exposure and considers the ways that both federal and state law respond to this. The chapter argues for universal drug testing of newborns in an effort to ascertain whether they have been prenatally exposed to such substances so that treatment and other services can be provided.

Purpose: Safety net hospitals (SNH) have been associated with inferior surgical outcomes and increased resource use. Utilization and outcomes for extracorporeal membrane oxygenation (ECMO), a rescue modality for patients with respiratory or cardiac failure, may vary by safety net status. We hypothesized SNH to be associated with inferior outcomes and costs of ECMO in a national cohort. Materials and Methods: The 2008-2017 National Inpatient Sample was queried for ECMO hospitalizations and safety net hospitals were identified. Multivariable regression was used to perform risk-adjusted comparisons of mortality, complications and resource utilization at safety net and non-safety net hospitals. Results: Of 36,491 ECMO hospitalizations, 28.2% were at SNH. On adjusted comparison SNH was associated with increased odds of mortality (AOR: 1.23), tracheostomy use (AOR: 1.51), intracranial hemorrhage (AOR: 1.39), as well as infectious complications (AOR: 1.21, all P < .05), with NSNH as reference. SNH was also associated with increased hospitalization duration (β=+4.5 days) and hospitalization costs (β=+$32,880, all P < .01). Conclusions: We have found SNH to be associated with inferior survival, increased complications, and higher costs compared to NSNH. These disparate outcomes warrant further studies examining systemic and hospital-level factors that may impact outcomes and resource use of ECMO at SNH.

Abstract Background Homelessness has been a growing issue in the United States and worldwide. Bartonella quintana, the causative agent of “Trench fever”, is a well known illness among homeless populations in urban centers. While many cases of B. quintana are self limited, the disease can have advanced presentations including endocarditis. We present a short case series of three cases of B. quintana infective endocarditis (IE) in homeless individuals in Los Angeles and review the literature of cases of B. quintana IE in the homeless population. Methods Here we report three cases of B. quintana IE encountered in homeless individuals at the University of California, Los Angeles (UCLA) hospital system. A literature review was also conducted. PubMed was searched for published cases of human IE secondary to B. quintana in homeless individuals. Results All three patients were male with ages ranging from 39 to 57 years old with a history of homelessness and alcohol use. Presentations were subacute to chronic in nature consisting of constitutional symptoms as well as a range of symptoms corresponding with heart and renal failure. Each patient was found to have varying degrees of aortic insufficiency with either identified aortic valve vegetation or valvular thickening. Diagnosis was made with a combination of Bartonella serologies and whole genome sequencing PCR. All three patient’s courses were complicated by renal failure at varying points limiting the use of gentamicin for the full treatment course. Two patients ultimately underwent aortic valve replacement due to severe aortic insufficiency and completed therapy with doxycycline and rifampin. A single patient was discharged with plan to complete doxycycline and rifampin therapy however was lost to follow up. A literature review of 10 manuscripts describing 13 cases of B. quintana IE were identified. All the patients were male and the median age was 45. Six of the cases were in Europe and eight were in North America. All cases had left sided valve involvement (10 aortic, 6 mitral, 3 both valves). No cases of right sided IE were identified. Conclusion B. quintana IE should be considered in homeless patients with a clinical presentation concerning for IE. A combination of serology and PCR testing can be useful in diagnosis of this uncommon cause of infective endocarditis. Disclosures Jeffrey Klausner, MD, MPH, Nothing to disclose

Abstract Background There has been a dramatic rise in IV drug use (IVDU) and its associated mortality and morbidity, however, the scope of this effect has not been described. Kentucky is at the epicenter of this epidemic and is an ideal place to better understand the health complications of IVDU in order to improve outcomes. Methods All adult in-patient admissions to University of Kentucky hospitals in 2018 with an Infectious Diseases (ID) consult and an ICD 9/10 code associated with IVDU underwent thorough retrospective chart review. Demographic, descriptive, and outcome data were collected and analyzed by standard statistical analysis. Results 390 patients (467 visits) met study criteria. The top illicit substances used were methamphetamine (37.2%), heroin (38.2%), and cocaine (10.3%). While only 4.1% of tested patients were HIV+, 74.2% were HCV antibody positive. Endocarditis (41.1%), vertebral osteomyelitis (20.8%), bacteremia without endocarditis (14.1%), abscess (12.4%), and septic arthritis (10.4%) were the most common infectious complications. The in-patient death rate was 3.0%, and 32.2% of patients were readmitted within the study period. The average length of stay was 26 days. In multivariable analysis, infectious endocarditis was associated with a statistically significant increase in risk of death, ICU admission, and hospital readmission. Although not statistically significant, trends toward mortality and ICU admission were identified for patients with prior endocarditis and methadone was correlated with decreased risk of readmission and ICU stay. FIGURE 1: Reported Substances Used FIGURE 2: Comorbidities FIGURE 3: Types of Severe Infectious Complications Conclusion We report on a novel, comprehensive perspective on the serious infectious complications of IVDU in an attempt to measure its cumulative impact in an unbiased way. This preliminary analysis of a much larger dataset (2008-2019) reveals some sobering statistics about the impact of IVDU in the United States. While it confirms the well accepted mortality and morbidity associated with infective endocarditis and bacteremia, there is a significant unrecognized impact of other infectious etiologies. Additional analysis of this data set will be aimed at identifying key predictive factors in poor outcomes in hopes of mitigating them. Disclosures All Authors: No reported disclosures
