Abstract
This review addresses current views on prevention of infectious endocarditis (IE). History of establishing the concept of antibacterial prophylaxis (ABP), major approaches, and substantiation of changes in ABP in recent years are described. Recent international and national guidelines are highlighted, specifically, guidelines of the European Society of Cardiologists, American Heart Association/American College of Cardiology, and the Japanese Circulation Society. The review presents critical evaluation of previously approved international guidelines, including analysis of the effect of partial or complete ABP restriction on IE morbidity and incidence of complications. Special attention is paid to awareness of practitioners, particularly dentists, about ABP issues in their practice. Aspects of validity and key features of preventive approaches in implanting cardiac electronic devices and transcatheter aortic valve implantation are discussed.

Abstract
BACKGROUND Injection drug use-associated infective endocarditis (IDU-IE) is a growing epidemic. The objective of this survey was to identify the beliefs and practice patterns of Canadian cardiac surgeons regarding surgical management of IDU-IE. METHODS A 30-question survey was developed by a working group and distributed to all practicing adult cardiac surgeons in Canada. Data were analyzed using descriptive statistics. RESULTS Of 146 surgeons, 94 completed the survey (64%). Half of surgeons (49%) would be less likely to operate on patients with IE if associated with IDU. In the case of prosthetic valve IE owing to continued IDU, 36% were willing to reoperate once and 14% were willing to reoperate twice or more. Most surgeons required commitments from patients before surgery (73%), and most referred patients to addiction services (81%). Some surgeons would offer a Ross procedure (10%) or homograft (8%) for aortic valve IE, and 47% would consider temporary mechanical circulatory support. Whereas only 17% of surgeons worked at an institution with an endocarditis team, 71% agreed that there was a need for one at each institution. Most surgeons supported the development of IDU-IE-specific guidelines (80%). CONCLUSIONS Practice patterns and surgical management of IDU-IE vary considerably across Canada. Areas of clinical unmet needs include the development of a formal addiction services referral protocol for patients, the development of an interdisciplinary endocarditis team, as well as the creation of IDU-IE clinical practice guidelines.

Novel Routes of Potential Hepatitis C Virus Transmission among People Who Inject Drugs: Secondary Blood Exposures Related to Injection Drug Use. Subst Use Misuse 2021; 56:751-757.

Abstract
BACKGROUND The US is in the midst of a national Hepatitis C Virus (HCV) epidemic that appears to be driven by new cases among people who inject drugs (PWID). While HCV transmission among PWID is believed to occur mostly through direct sharing of syringes, some infections may be spread via secondary processes and materials involved in injecting. OBJECTIVES Here, we present the prevalence of secondary blood exposures on clothing and nearby surfaces after injection episodes and examine the correlations of these exposures to lifetime HCV infection among a targeted sample of 553 PWID in Los Angeles and San Francisco, California in 2016-18. RESULTS In multivariate logistic regression models, higher odds of blood on clothing in the last 30 days was significantly (p < 0.05) associated with lifetime positive HCV status, opioids as primary drug, injecting with others, sharing cookers, and receptive syringe sharing. Higher adjusted odds of blood on nearby surfaces in the last 30 days was significantly associated with lifetime positive HCV status, sharing cookers, and receptive syringe sharing. Native American race was associated with significantly lower adjusted odds of both outcome variables. Conclusions/Importance: Results indicate the relevance of physical and social micro-environments to the potential for blood exposures secondary to injection episodes. Individuals with chronic HCV seropositivity are potentially more likely to expose others to blood due to decreases in the blood's ability to clot. This highlights the need for increased HCV testing at harm reduction sites and increased supply of first aid and wound-care materials to help stop potential blood exposures after injection episodes.

Abstract
U.S. cardiac surgeons encounter complex decision-making when treating patients with injection drug use-associated infective endocarditis (IDU-IE). We evaluated surgeons' treatment approaches for IDU-IE compared to non-IDU-IE. This is an anonymous survey of U.S. cardiac surgeons who answered hypothetical infective endocarditis (IE) clinical scenarios that varied based on patient substance use history, addiction treatment, and history of IE. Treatment approaches were classified as operative vs nonoperative. Responses were descriptively analyzed. The survey response rate was 8.7% (n = 208). Survey respondents were mostly male (85.6%) and non-Hispanic white (67.8%), but were from all regions of the United States. Surgeons reported they would operate at similar proportions for patients with native valve non-IDU-IE (63%) and IDU-IE engaged in methadone treatment (64.5%). Most surgeons reported they would operate on patients with recurrent non-IDU-IE (93.1%) compared to only 26.4% for patients with recurrent IDU-IE (P < 0.001). Most surgeons reported they would place no limits on the number of operations for patients with recurrent non-IDU-IE (73.1%), whereas 83.5% of surgeons would limit the number of surgeries for patients with recurrent IDU-IE (P < 0.001). Most respondents reported having declined to operate on patients with IDU-IE (63.5%). Cardiac surgeons are less likely to report favoring operative management for primary and recurrent infection in patients with IDU-IE, though patient engagement in methadone treatment increased the likelihood of them taking an operative approach. There is opportunity to standardize the care, including addiction treatment, of patients with IDU-IE to optimize positive short and long-term outcomes.

Harm Reduct J 2020; 17:96. [PMID: 33267848 PMCID: PMC7709308 DOI: 10.1186/s12954-020-00447-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Accepted: 11/20/2020] [Indexed: 12/31/2022] Open
Abstract
Introduction Skin and soft tissue infections (SSTIs) are among the leading causes of morbidity and mortality for people who inject drugs (PWID). Studies demonstrate that certain injection practices correlate with SSTI incidence among PWID. The opioid epidemic in the USA has particularly affected rural communities, where access to prevention and treatment presents unique challenges. This study aims to estimate unsafe injection practices among rural-dwelling PWID; assess treatments utilized for injection related SSTIs; and gather data to help reduce the overall risk of injection-related SSTIs. Methods Thirteen questions specific to SSTIs and injection practices were added to a larger study assessing unmet health care needs among PWID and were administered at six syringe exchange programs in rural Wisconsin between May and July 2019. SSTI history prevalence was estimated based on infections reported within one-year prior of response and was compared to self-reported demographics and injection practices. Results Eighty responses were collected and analyzed. Respondents were white (77.5%), males (60%), between the ages 30 and 39 (42.5%), and have a high school diploma or GED (38.75%). The majority of respondents (77.5%) reported no history of SSTI within the year prior to survey response. Females were over three times more likely to report SSTI history (OR = 3.07, p = 0.038) compared to males. Water sources for drug dilution (p = 0.093) and frequency of injecting on first attempt (p = 0.037), but not proper skin cleaning method (p = 0.378), were significantly associated with a history of SSTI. Injecting into skin (p = 0.038) or muscle (p = 0.001) was significantly associated with a history of SSTI. Injection into veins was not significantly associated with SSTI (p = 0.333).
Conclusion Higher-risk injection practices were common among participants reporting a history of SSTIs in this rural sample. Studies exploring socio-demographic factors influencing risky injection practices and general barriers to safer injection practices to prevent SSTIs are warranted. Dissemination of education materials targeting SSTI prevention and intervention among PWID not in treatment is warranted.

Abstract
BACKGROUND Opioid use disorder, defined as a pattern of problematic opioid use leading to clinically significant impairment, has resulted in considerable morbidity and mortality throughout the world. This is due, at least in part, to the marginalized status of patients with opioid use disorder, limiting their access to appropriate laboratory testing, diagnosis, and treatment. Infections have long been associated with illicit drug use and contribute considerably to morbidity and mortality. However, barriers to testing and negative stigmas associated with opioid use disorder present unique challenges to infectious disease testing in this patient population. CONTENT This review addresses the associations between opioid use disorder and infectious organisms, highlighting the health disparities encountered by patients with opioid use disorder, and the important role of laboratory testing for diagnosing and managing these patients. SUMMARY Infections are among the most frequent and adverse complications among patients with opioid use disorder. As a result of health disparities and systemic biases, patients that misuse opioids are less likely to receive laboratory testing and treatment. However, laboratories play a crucial in identifying patients that use drugs illicitly and infections associated with illicit drug use.

Abstract
BACKGROUND Injection drug use has far-reaching social, economic, and health consequences. Serious bacterial infections, including skin/soft tissue infections, osteomyelitis, bacteremia, and endocarditis, are particularly morbid and mortal consequences of injection drug use. METHODS We conducted a population-based retrospective cohort analysis of hospitalizations among patients with a diagnosis code for substance use and a serious bacterial infection during the same hospital admission using Oregon Hospital Discharge Data. We examined trends in hospitalizations and costs of hospitalizations attributable to injection drug use-related serious bacterial infections from January 1, 2008 through December 31, 2018. RESULTS From 2008 to 2018, Oregon hospital discharge data included 4,084,743 hospitalizations among 2,090,359 patients. During the study period, hospitalizations for injection drug use-related serious bacterial infection increased from 980 to 6,265 per year, or from 0.26% to 1.68% of all hospitalizations (P<0.001). The number of unique patients with an injection drug use-related serious bacterial infection increased from 839 to 5,055, or from 2.52% to 8.46% of all patients (P<0.001). While hospitalizations for all injection drug use-related serious bacterial infections increased over the study period, bacteremia/sepsis hospitalizations rose most rapidly with an 18-fold increase. Opioid use diagnoses accounted for the largest percentage of hospitalizations for injection drug use-related serious bacterial infections, but hospitalizations for amphetamine-type stimulant-related serious bacterial infections rose most rapidly with a 15-fold increase. People living with HIV and HCV experienced increases in hospitalizations for injection drug use-related serious bacterial infection during the study period. Overall, the total cost of hospitalizations for injection drug use-related serious bacterial infections increased from $16,305,129 in 2008 to $150,879,237 in 2018 (P<0.001). CONCLUSIONS In Oregon, hospitalizations for injection drug use-related serious bacterial infections increased dramatically and exacted a substantial cost on the health care system from 2008 to 2018. This increase in hospitalizations represents an opportunity to initiate substance use disorder treatment and harm reduction services to improve outcomes for people who inject drugs.

Abstract
With over 20 years of the opioid crisis, our collective response has evolved to address the ongoing needs related to the management of opioid use and opioid use disorder. There has been an increasing recognition of the need for standardized metrics to evaluate organizational management and stewardship. The clinical laboratory, with a wealth of objective and quantitative health information, is uniquely poised to support opioid stewardship and drive valuable metrics for opioid prescribing practices and opioid use disorder (OUD) management. To identify laboratory-related insights that support these patient populations, a collection of 5 independent institutions, under the umbrella of the Clinical Laboratory 2.0 movement, developed and prioritized metrics. Using a structured expert panel review, laboratory experts from 5 institutions assessed possible metrics as to their relative importance, usability, feasibility, and scientific acceptability based on the National Quality Forum criteria. A total of 37 metrics spanning the topics of pain and substance use disorder (SUD) management were developed with consideration of how laboratory insights can impact clinical care. Monitoring these metrics, in the form of summative reports, dashboards, or embedded in laboratory reports themselves may support the clinical care teams and health systems in addressing the opioid crisis. The clinical insights and standardized metrics derived from the clinical laboratory during the opioid crisis exemplifies the value proposition of clinical laboratories shifting into a more active role in the healthcare system. This increased participation by the clinical laboratories may improve patient safety and reduce healthcare costs related to OUD and pain management.

Abstract
BACKGROUND Skin and soft tissue infections (SSTI) are common complications of injection drug use. We aimed to determine if rehospitalization and recurrent SSTI differ among persons with opioid use disorder (OUD) hospitalized for SSTI who are initiated on MOUD within 30 days of discharge and those who are not. METHODS We performed a retrospective analysis of commercially insured adults aged 18 years and older in the U.S. with OUD and hospitalization for injection-related SSTI from 2010-2017. The primary exposure was initiation of MOUD in the 30 days following hospitalization for SSTI. The primary outcomes included 30-day and 1-year 1) all-cause rehospitalization and 2) recurrent SSTI. We calculated the incidence rates for the two groups: MOUD group and no MOUD group for the primary outcomes. We developed Cox models to determine if rehospitalization and recurrent SSTI differ between the two groups. RESULTS Only 5.5 % (357/6538) of people received MOUD in the month following their index SSTI hospitalization. 30-day rehospitalization incidence was higher in the MOUD group compared to no MOUD (35.9 vs 27.5 per 100 person-30 days) and one-year SSTI recurrence was lower (10.3 vs 18.7 per 100 person-years). In multivariable modeling, the MOUD group remained at significantly higher risk of 30-day rehospitalization compared to the no MOUD group and at lower risk for one-year SSTI recurrence. CONCLUSIONS MOUD receipt following SSTI hospitalization decreases risk of recurrent SSTI among persons with OUD. Further expansion of these in-hospital services could provide an effective tool in the U.S. response to the opioid epidemic.

Abstract
BACKGROUND Infective endocarditis (IE) often requires surgical intervention. An increasingly common cause of IE is injection drug use (IDU-IE). There is conflicting evidence on whether postoperative mortality differs between people with IDU-IE and people with IE from etiologies other than injection drug use (non-IDU-IE). In this manuscript, we compare short-term postoperative mortality in IDU-IE vs non-IDU-IE through systematic review and meta-analysis. METHODS The review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Publication databases were queried for key terms included in articles up to September 2017. Randomized controlled trials, prospective cohorts, or retrospective cohorts that reported on 30-day mortality or in-hospital/operative mortality following valve surgery and that compared outcomes between IDU-IE and non-IDU-IE were included. RESULTS Thirteen studies with 1593 patients (n = 341 [21.4%] IDU-IE) were included in the meta-analysis. IDU-IE patients more frequently had tricuspid valve infection, Staphylococcus infection, and heart failure before surgery. Meta-analysis revealed no statistically significant difference in 30-day postsurgical mortality or in-hospital mortality between the 2 groups. CONCLUSIONS Despite differing preoperative clinical characteristics, early postoperative mortality does not differ between IDU-IE and non-IDU-IE patients who undergo valve surgery. Future research on long-term outcomes following valve replacement is needed to identify opportunities for improved healthcare delivery with IDU-IE.

Abstract
Abstract
Background
People who inject drugs (PWID) are at increased risk of deleterious sequelae due to infective endocarditis (IE). A standardized, hospital-wide drug use–associated infection protocol targeting medication safety, pain management, and limiting external risk factors was implemented at an academic medical center to improve outcomes in PWID with IE.
Methods
A quasi-experimental study included patients with active injection drug use and definite IE from January 2013 to July 2017 (preintervention group) and from September 2017 to January 2019 (intervention group). The primary outcome of interest was the 90-day all-cause readmission rate. Secondary outcomes included infection-related readmission rates, in-hospital and all-cause mortality rates, and the frequency of patients leaving against medical advice.
Results
A total of 168 patients were included, in the 100 preintervention and 68 in the intervention group. Patients in the intervention group had reduced odds of 90-day all-cause readmission (adjusted odds ratio, 0.2; 95% confidence interval, 0.08–0.6) after adjustment for confounding variables. The 12-month all-cause mortality rate was also significantly reduced in the intervention group (adjusted odds ratio, 0.25; 95% confidence interval, .07–.89). The intervention group had a higher proportion of patients leaving against medical advice (6% for the preintervention group vs 35% for the intervention group, P < .001).
Conclusions
A drug use–associated infection protocol demonstrated reduced 90-day all-cause readmission and 12-month all-cause mortality rates in PWID with IE. This study highlights the importance of standardized care processes for improving care in this specialized patient population.

Abstract
Infective endocarditis associated with injection drug use (IDU-IE) is markedly increasing in the United States and Canada. Long-term outcomes are dismal and stem from insufficient substance use disorder treatment. In this review, we summarize the principles of antimicrobial and surgical management for infective endocarditis associated with injection drug use. We discuss approaches to opioid use disorder care and harm reduction in the inpatient setting and review opportunities to address preventable infections among persons injecting drugs. We highlight barriers to implementing optimal treatment and consider novel approaches that may reshape infective endocarditis associated with injection drug use treatment in coming years.

Abstract
BACKGROUND Opioid abuse is a significant cause of morbidity and mortality in the United States, and injection drug use (IDU) is a common form of opioid abuse. IDU is a major risk factor for infections including infective endocarditis (IE). OBJECTIVES To determine the prevalence of opioid abuse among patients with IE in both patient problem lists and diagnostic codes and describe underlying patient characteristics. METHODS A retrospective chart review from 1-1-2010 to 11-19-2018 of a large academic medical center's patients with documented IE was performed. Demographic, comorbidity, opioid prescription data and records of drug abuse in both the patient's problem list and ICD9/10 codes were recorded. RESULTS Of the 796 patients with documented IE, 105 patients (13.2%) had opioid abuse or related IDU in their problem list, but only 22 received an ICD-9/10 code associated with drug abuse. IE patients with opioid abuse were generally younger (43.6 vs 61.7 years [P < 0.001]), had fewer chronic comorbidities, and were prescribed opioids more often (86.7% vs 53.8% [P < 0.001]). CONCLUSIONS Opioid abuse and IDU are commonly recorded in the problem list of patients with IE, but opioid abuse is frequently not listed as a diagnosis in administrative billing codes.

Disparities in United States hospitalizations for serious infections in patients with and without opioid use disorder: A nationwide observational study. PLoS Med 2020; 17:e1003247.

Abstract
BACKGROUND Patients with opioid use disorder (OUD) who are hospitalized for serious infections requiring prolonged intravenous antibiotics may face barriers to discharge, which could prolong hospital length of stay (LOS) and increase financial burden. We investigated differences in LOS, discharge disposition, and charges between hospitalizations for serious infections in patients with and without OUD. METHODS AND FINDINGS We utilized the 2016 National Inpatient Sample-a nationally representative database of all discharges from US acute care hospitals. The population of interest was all hospitalizations for infective endocarditis, epidural abscess, septic arthritis, or osteomyelitis. The exposure was OUD, and the primary outcome was LOS until discharge, assessed by using a competing risks analysis to estimate adjusted hazard ratios (aHRs). Adjusted odds ratio (aOR) of discharge disposition and adjusted differences in hospital charges were also reported. Of 95,470 estimated hospitalizations for serious infections (infective endocarditis, epidural abscess, septic arthritis, and osteomyelitis), the mean age was 49 years and 35% were female. 46% had Medicare (government-based insurance coverage for people age 65+ years), and 70% were non-Hispanic white. After adjustment for potential confounders, OUD was associated with a lower probability of discharge at any given LOS (aHR 0.61; 95% CI 0.59-0.63; p < 0.001). OUD was also associated with lower odds of discharge to home (aOR 0.38; 95% CI 0.33-0.43; p < 0.001) and higher odds of discharge to a post-acute care facility (aOR 1.85; 95% CI 1.57-2.17; p < 0.001) or patient-directed discharge (also referred to as "discharge against medical advice") (aOR 3.47; 95% CI 2.80-4.29; p < 0.001). There was no significant difference in average total hospital charges, though daily hospital charges were significantly lower for patients with OUD. Limitations include the potential for unmeasured confounders and the use of billing codes to identify cohorts. CONCLUSIONS Our findings suggest that among hospitalizations for some serious infections, those involving patients with OUD were associated with longer LOS, higher odds of discharge to post-acute care facilities or patient-directed discharge, and similar total hospital charges, despite lower daily charges. These findings highlight opportunities to improve care for patients with OUD hospitalized with serious infections, and to reduce the growing associated costs.

Abstract
Background Prior studies have used International Classification of Disease (ICD) diagnosis codes in administrative data to identify patients with infective endocarditis (IE) associated with intravenous drug use (IVDU). Little is known about the accuracy of ICD codes for IVDU-IE. Methods We used 2 previously described algorithms to identify patients with potential IVDU-IE admitted to 125 Veterans Administration hospitals from January 2010 through December 2018. Algorithm A identified patients with concurrent ICD-9/10 codes for IE and drug use during the same admission. Algorithm B identified patients with drug use coded either during the IE admission or during outpatient or other visits within 6 months of admission. We reviewed 400 randomly selected patient charts to determine the positive predictive value (PPV) of each algorithm for clinical documentation of IE, any drug use, IVDU, and IVDU-IE, respectively. Results Algorithm A identified 788 patients, and B identified 1314 patients, a 68% increase. PPVs were high for clinical documentation of diagnoses of IE (86.5% for A and 82.6% for B) and any drug use (99.0% and 96.3%). PPVs were lower for documented IVDU (74.5% and 64.1%) and combined diagnoses of IVDU-IE (65.0% and 55.2%), partly because of a lack of ICD codes specific to IVDU. Among patients identified by algorithm B but not A, 72% had clinical documentation of drug use during the IE admission, indicating a failure of algorithm A to capture cases due to incomplete recording of inpatient ICD codes for drug use. Conclusions There is need for improved algorithms for IVDU-IE surveillance during the ongoing opioid epidemic.

Abstract
BACKGROUND The rising incidence of infective endocarditis (IE) among people who inject drugs (PWID) has been a major concern across North America. The coincident rise in IE and change of drug preference to hydromorphone controlled-release (CR) among our PWID population in London, Ontario intrigued us to study the details of injection practices leading to IE, which have not been well characterized in literature. METHODS A case-control study, using one-on-one interviews to understand risk factors and injection practices associated with IE among PWID was conducted. Eligible participants included those who had injected drugs within the last 3 months, were > 18 years old and either never had or were currently admitted for an IE episode. Cases were recruited from the tertiary care centers and controls without IE were recruited from outpatient clinics and addiction clinics in London, Ontario. RESULTS Thirty three cases (PWID IE+) and 102 controls (PWID but IE-) were interviewed. Multivariable logistic regressions showed that the odds of having IE were 4.65 times higher among females (95% CI 1.85, 12.28; p = 0.001) and 5.76 times higher among PWID who did not use clean injection equipment from the provincial distribution networks (95% CI 2.37, 14.91; p < 0.001). Injecting into multiple sites and heating hydromorphone-CR prior to injection were not found to be significantly associated with IE. Hydromorphone-CR was the most commonly injected drug in both groups (90.9% cases; 81.4% controls; p = 0.197). DISCUSSION Our study highlights the importance of distributing clean injection materials for IE prevention. Furthermore, our study showcases that females are at higher risk of IE, which is contrary to the reported literature. Gender differences in injection techniques, which may place women at higher risk of IE, require further study. We suspect that the very high prevalence of hydromorphone-CR use made our sample size too small to identify a significant association between its use and IE, which has been established in the literature.

Abstract
BACKGROUND Addiction Consult Services care for hospitalized patients with substance use disorders (SUD), who frequently utilize costly medical services. This study evaluates whether an addiction consult is associated with 30-day acute care utilization. METHODS This was a retrospective cohort study of 3905 inpatients with SUD. Acute care utilization was defined as any emergency department visit or re-hospitalization within 30 days of discharge. Inverse probability of treatment weighted generalized estimating equations logistic regression models were used to evaluate the relationship between receipt of an addiction consult and 30-day acute care utilization. Exploratory subgroup analyses were performed to describe whether this association differed by type of SUD and discharge on medication for addiction treatment. RESULTS The 30-day acute care utilization rate was 39.5 % among patients with a consult and 36.0 % among those without. Addiction consults were not significantly associated with care utilization (Adjusted Odds Ratio 1.02; 0.82, 1.28). No significant differences were detected in subgroup analyses; however, the decreased odds among patients with OUD given medication was clinically notable (AOR 0.69; 0.47, 1.02). DISCUSSION Repeat acute care utilization is common among hospitalized patients with SUD, particularly those seen by the addiction consult services. While this study did not detect a significant association between addiction consults and 30-day acute care utilization, this relationship merits further evaluation using prospective studies, controlling for key confounders and with a focus on the impact of medications for opioid use disorder.

Abstract
Background Within the context of Canada’s opioid crisis, medical complications associated with intravenous drug use (IVDU) are increasing. Infective endocarditis (IE) is a serious complication of IVDU, and understanding the characteristics of these patients could aid health systems, clinicians, and patients in the optimization of treatment and prevention of IVDU-IE. Methods At a tertiary care hospital in southern New Brunswick, we conducted a retrospective chart review to identify patients with IVDU-IE admitted between January 1, 2013, and December 31, 2017. We collected data related to the epidemiology, microbiology, clinical manifestations, echocardiography, complications during hospital admission, and outcomes. Results Forty-two cases of IVDU-IE met inclusion criteria. The rate of IVDU-IE increased from 2.28 per 100,000 population in 2014 to 4.00 in 2017, which, although not statistically significant, reflects patterns in other jurisdictions. Most patients (72.4%) were male, and the mean age was 38.3 (±11.5) years. Most patients (79.3%) injected opioids. The most common clinical sign was fever (90.5%), and Staphylococcus aureus (61.9%) was the most common microorganism. The tricuspid valve was most commonly infected (58.5%), 50% of cases had heart failure as a complication during admission, and 45.2% of cases required valve replacement or repair. The 2-year survival rate after admission for initial IVDU-IE episode was 62.0% (95% confidence interval: 36.5-79.7). Conclusion IVDU-IE is common in New Brunswick and may be increasing. Despite the relatively young age of this patient population, IVDU-IE is associated with significant morbidity and mortality. Expanding effective harm reduction and addiction treatment strategies for this cohort is recommended.

The Evolving Burden of Drug Use Associated Infective Endocarditis in the United States. Ann Thorac Surg 2020; 110:1185-1192. [PMID: 32387035 DOI: 10.1016/j.athoracsur.2020.03.089] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Revised: 03/17/2020] [Accepted: 03/25/2020] [Indexed: 01/04/2023]
Abstract
BACKGROUND The rise in the number of valve operations performed for infective endocarditis (IE) due to drug use is an important manifestation of the opioid epidemic. This study characterized national trends and outcomes of valve surgery for drug use-associated IE (DU-IE). METHODS Adults undergoing valve surgery for active IE in The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database between July 2011 and June 2018 were stratified as DU-IE and non-DU-IE. Trends and clinical profiles were analyzed. Early outcomes were assessed. The association of DU-IE with outcomes was analyzed with multivariable regression, adjusting for STS Valve Risk model covariates. RESULTS There were 34,905 valve operations performed for IE, of which 33.7% were for DU-IE. DU-IE operations increased 2.7-fold during the study period. There was considerable regional variability in DU-IE operations, ranging from 28% to 58% of all IE surgeries in 2018, with highest rates observed in East South Central and South Atlantic regions. DU-IE patients were younger and had fewer cardiovascular comorbidities. Risk-adjusted major morbidity and in-hospital mortality were significantly higher in the DU-IE group. Redo valve procedures in DU-IE patients were associated with worse outcomes, compared with those receiving a first valve operation. CONCLUSIONS Operations for DU-IE have increased sharply in the United States during the last several years, exhibiting substantial regional variability. DU-IE patients have unique clinical profiles, and worse risk-adjusted outcomes. This demonstrates the significant impact of the opioid epidemic on endocarditis surgeries and punctuates the urgent need for multidisciplinary regional and national efforts to reverse this trend.

Abstract
OBJECTIVE To assess contemporary trends in the incidence, characteristics, and outcomes of hospital admissions for infective endocarditis (IE) in the United States. PATIENTS AND METHODS Patients ≥18 years admitted with IE between January 1, 2003, and December 31, 2016, were identified in the National Inpatient Sample. We assessed the annual incidence, clinical characteristics, morbidity, mortality, and cost of IE-related hospitalizations. RESULTS The incidence of IE-related hospitalizations increased from 34,488 (15.9; 95% confidence interval [CI], 15.73, 16.06) per 100,000 adults) in 2003 to 54,405 (21.8; 95% CI, 21.60-21.97) per 100,000 adults) in 2016 (P<.001). The prevalence of patients below 30 years of age, and those who inject drugs, increased from 7.3% to 14.5% and from 4.8% to 15.1%, respectively (P<.001). The annual volume of valve surgery for IE increased from 4049 in 2003 to 6460 in 2016 (P<.001), but the ratio of valve surgery to IE-hospitalizations did not decrease (11.7% in 2003; 11.8% in 2016). There was also a temporal increase in risk-adjusted rates of stroke (8.0% to 13.2%), septic shock (5.4% to 16.3%), and mechanical ventilation (7.7% to 16.5%; P<.001). However, risk-adjusted mortality decreased from 14.4% to 9.8% (P<.001). Median length-of-stay and mean inflation-adjusted cost decreased from 11 to 10 days and from $45,810±$61,787 to $43,020±$55,244, respectively, (P<.001). Nonetheless, the expenditure on IE hospitalizations increased ($1.58 billion in 2003 to $2.34 billion in 2016; P<.001). CONCLUSIONS There is a substantial recent rise in endocarditis hospitalizations in the United States. Although the adjusted in-hospital mortality of endocarditis and the cost of admission decreased over time, the overall expenditure on in-hospital care for endocarditis increased.

Reasons for assisting with injection initiation: Results from a large survey of people who inject drugs in Los Angeles and San Francisco, California. Drug Alcohol Depend 2020; 209:107885. [PMID: 32058244 PMCID: PMC7127951 DOI: 10.1016/j.drugalcdep.2020.107885] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2019] [Revised: 01/25/2020] [Accepted: 01/28/2020] [Indexed: 11/23/2022]
Abstract
UNLABELLED Injection drug initiation usually requires assistance by someone who already injects drugs. To develop interventions that prevent people from starting to inject drugs, it is imperative to understand why people who inject drugs (PWID) assist with injection initiation. METHODS Injection initiation history and motives for initiating others were collected from 978 PWID in Los Angeles and San Francisco, CA, from 2016-17. This article documents motivations for providing injection initiation assistance and examines demographic, economic, and health-related factors associated with these motivations using multivariable logistic regression modeling. RESULTS Among the 405 PWID who ever facilitated injection initiation, motivations for initiating were: injury prevention (66%), skilled at injecting others (65%), to avoid being pestered (41%), in exchange for drugs/money (45%), and for food/shelter/transportation (15%). High frequency initiation (>5 lifetime injection initiations) was associated with all motivations except for being pestered. Initiation to prevent injury was associated with being female. Initiation due to pestering was associated with recycling income and sex work. Being skilled was associated with age and HIV status, while initiation for money or drugs was associated with age, race, education, social security income, and substance use treatment. Lastly, initiation for food, shelter, or transportation was associated with age, sexual orientation and education level. CONCLUSION Diverse factors were associated with reported motivations for assisting someone to initiate injection for the first time. Our analysis underscores the need for prevention strategies focused on improving economic and housing conditions along with implementing drug consumption rooms to disrupt the social processes of injection initiation.

Abstract
Objectives Infective endocarditis (IE) with non-HACEK Gram-negative (GN) organisms is rare, but associated with poor outcomes. The purpose of this study was to quantify the microbiology, treatment strategies, and frequency of poor outcomes in patients with non-HACEK GN IE. Materials Retrospective cohort of adults with definite non-HACEK GN IE from 1/11-1/19. The primary endpoint was poor patient outcome, defined as a composite of all-cause death or infection-related readmission within 90-days of index infection. Results 43 patients were included: 51% patients were men, and the median (IQR) age was 40 (31–50) years. Forty patients reported injection drug use. The most common organisms were Pseudomonas aeruginosa (68%) and Serratia marcescens (9%). Seventy-six percent of patients received definitive combination therapy; the most common antibiotics used in combination with a β-lactam were aminoglycosides (50%) and fluoroquinolones (34%). Three patients discontinued combination therapy due to toxicity. Twelve-month, all-cause mortality and readmission was 30% and 54%, respectively. In multivariable logistic regression, variables independently associated with composite poor outcome were receipt of fluoroquinolone-based IE combination therapy and septic shock. Conclusions Long-term mortality and readmission rates were high. Patients who received fluoroquinolone-based IE combination therapy more frequently developed poor outcomes than those who did not.

Abstract
PURPOSE The purpose of this study was to describe left-sided infective endocarditis (LSIE) in persons who inject drugs (PWID) and compare that group to PWID with non-LSIE and to non-PWID with LSIE. METHODS Retrospective single-center study of adult IE patients from 2011 to 2018. RESULTS Of the 333 patients in our cohort, 54 were PWID with LSIE, 75 were PWID with non-LSIE, and 204 were non-PWID with LSIE. When comparing LSIE vs non-LSIE in PWID, the LSIE group was older (median age 35 vs 28.5, p < 0.01), had fewer S. aureus infections (59% vs 92%, p < 0.01), was more likely to have cardiac surgery (31% vs 13%, p < 0.01), and had a higher 10-week mortality (22% vs 5%, p < 0.01). When comparing PWID with LSIE to non-PWID with LSIE, the PWID group were younger (median age 35 vs 46, p < 0.01); had more frequent multi-valve involvement (33% vs 19%, p = 0.04), Staphylococcus aureus infections (54% vs 27%, p < 0.01), and previous IE (24% vs 8%, p < 0.01); and experienced more strokes (54% vs 31%, p < 0.01). Ten-week mortality was similar for LSIE in both PWID and non-PWID (24% vs 20%, p = 0.47). CONCLUSIONS LSIE in PWID is not uncommon. Compared to non-LSIE in PWID, valve surgery is more common and mortality is higher. For reasons that are unclear, stroke is more frequent in LSIE in PWID than in non-PWID with LSIE but mortality is no different.

Abstract
Background The incidence of infective endocarditis, a serious heart infection that can result from injection drug use, has increased in step with the opioid epidemic. Harm reduction services aimed at decreasing infectious complications of injection drug use are limited in rural areas; however, it is unknown whether the burden of opioid use–associated infective endocarditis varies between rural and urban populations. Methods We used 2003–2016 National (Nationwide) Inpatient Sample data and joinpoint regression to compare trends in hospitalization for opioid use–associated infective endocarditis between rural and urban populations. Results Rates of US hospitalizations for opioid use–associated infective endocarditis increased from 0.28 to 3.86 per 100 000 rural residents, as compared with 1.26 to 3.49 for urban residents (overall difference in annual percent change P < .01). We observed 2 distinct trend periods, with a period of little change between 2003 and 2009/2010 (annual percent change, 0.0% rural vs –0.08% urban) followed by a large increase in hospitalization rates between 2009/2010 and 2016 (annual percent change, 0.35% rural vs 0.36% urban). Over the study period, opioid use–associated infective endocarditis hospitalizations shifted toward younger age groups for both rural and urban residents, and rural resident hospitalizations increasingly occurred at urban teaching hospitals. For both groups, Medicaid was the most common payer. Conclusions The increase in US hospitalizations for opioid use–associated infective endocarditis over the past decade supports the importance of public health efforts to reduce injection-related infections in both urban and rural areas. Future studies should examine factors affecting the higher increase in rate of these hospitalizations in rural areas.

THE LANCET. INFECTIOUS DISEASES 2020; 20:487-497. [PMID: 31981474 DOI: 10.1016/s1473-3099(19)30705-4] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Revised: 08/03/2019] [Accepted: 11/12/2019] [Indexed: 01/09/2023]
Abstract
BACKGROUND The incidence of infective endocarditis related to injection drug use is increasing. On the basis of clinical practice and epidemiological and in-vitro data, we postulated that exposure to controlled-release hydromorphone is associated with an increased risk of infective endocarditis among people who inject drugs. METHODS We used linked health administrative databases in Ontario, Canada, to assemble a retrospective cohort of adults (aged 18-55 years) who inject drugs for the period of April 1, 2006, to Sept 30, 2015. Cases of infective endocarditis among this cohort were identified using International Classification of Diseases 10 codes. We estimated exposure to hydromorphone and risk of infective endocarditis among this cohort in two ways. First, in a population-level analysis, we identified patients living in regions with high (≥25%) and low (≤15%) hydromorphone prescription rates and, after matching 1:1 on various baseline characteristics, compared their frequency of infective endocarditis. Second, in a patient-level analysis including only those with prescription drug data, we identified those who had filled prescriptions (ie, received the drug from the pharmacy) for controlled-release or immediate-release hydromorphone and, after matching 1:1 on various baseline characteristics, compared their frequency of infective endocarditis with that of patients who had filled prescriptions for other opioids. RESULTS Between April 1, 2006, and Sept 30, 2015, 60 529 patients had evidence of injection drug use, 733 (1·2%, 95% CI 1·1-1·3) of whom had infective endocarditis. In the population-level analysis of 32 576 matched patients, we identified 254 (1·6%) admissions with infective endocarditis in regions with high hydromorphone use and 113 (0·7%) admissions in regions with low use (adjusted odds ratio [OR] 2·2, 95% CI 1·8-2·8, p<0·0001). In the patient-level analysis of 3884 matched patients, the frequency of infective endocarditis was higher among patients who filled prescriptions for hydromorphone than among those who filled prescriptions for non-hydromorphone opioids (2·8% [109 patients] vs 1·1% [41 patients]; adjusted OR 2·5, 95% CI 1·8-3·7, p<0·0001). This significant association was seen for controlled-release hydromorphone (3·9% [73 of 1895 patients] vs 1·1% [20 of 1895]; adjusted OR 3·3, 95% CI 2·1-5·6, p<0·0001), but not for immediate-release hydromorphone (1·8% [36 of 1989] vs 1·1% [21 of 1989]; 1·7, 0·9-3·6, p=0·072. INTERPRETATION Among people who inject drugs, the risk of infective endocarditis is significantly higher for those exposed to controlled-release hydromorphone than to other opioids. This association might be mediated by the controlled-release mechanism and should be the subject of further investigation.

THE JOURNAL OF IMMUNOLOGY 2020; 204:1188-1200.

Abstract
Endogenous opioid peptides are released at sites of injury, and their cognate G protein-coupled opioid receptors (ORs) are expressed on immune cells. Although drugs of misuse appropriate ORs, conflicting reports indicate immunostimulatory and immunosuppressive activity, in that opioid users have elevated infection risk, opioids activate innate immune cells, and opioids attenuate inflammation in murine T cell-mediated autoimmunity models. The i.v. use of drugs transmits bloodborne pathogens, particularly viruses, making the study of CD8+ T cells timely. From a cohort of nonuser controls and methadone users, we demonstrate, via t-Stochastic Neighbor Embedding and k-means cluster analysis of surface marker expression, that chronic opioid use alters human CD8+ T cell subset balance, with notable decreases in T effector memory RA+ cells. Studying global CD8+ T cell populations, there were no differences in expression of OR and several markers of functionality, demonstrating the need for finer analysis. Purified CD8+ T cells from controls respond to opioids ex vivo by increasing cytoplasmic calcium, a novel finding for OR signal transduction, likely because of cell lineage. CD8+ T cells from controls exposed to μ-OR agonists ex vivo decrease expression of activation markers CD69 and CD25, although the same markers are elevated in μ-OR-treated cells from methadone users. In contrast to control cells, T cell subsets from methadone users show decreased expression of CD69 and CD25 in response to TCR stimulus. Overall, these results indicate a direct, selective role for opioids in CD8+ T cell immune regulation via their ability to modulate cell responses through the opioid receptors and TCRs.

Abstract
BACKGROUND Endocarditis, once predominately found in older adults, is increasingly common among younger persons who inject drugs. Untreated opioid use disorder (OUD) complicates endocarditis management. We aimed to determine if rates of overdose and rehospitalization differ between persons with OUD with endocarditis who are initiated on medications for OUD (MOUDs) within 30 days of hospital discharge and those who are not. METHODS We performed a retrospective cohort study using a large commercial health insurance claims database of persons ≥18 years between July 1, 2010, and June 30, 2016. Primary outcomes included opioid-related overdoses and 1-year all-cause rehospitalization. We calculated incidence rates for the primary outcomes and developed Cox hazards models to predict time from discharge to each primary outcome as a function of receipt of MOUDs. RESULTS The cohort included 768 individuals (mean age 39 years, 51% male). Only 5.7% of people received MOUDs in the 30 days following hospitalization. The opioid-related overdose rate among those who did receive MOUDs in the 30 days following hospitalization was lower than among those who did not (5.8 per 100 person-years [95% confidence interval [CI], 5.1-6.4] vs 7.3 per 100-person years [95% CI, 7.1-7.5], respectively). The rate of 1-year rehospitalization among those who received MOUDs was also lower than those who did not (162.0 per 100 person-years [95% CI, 157.4-166.6] vs 255.4 per 100 person-years [95% CI, 254.0-256.8], respectively). In the Cox hazards models, the receipt of MOUDs was not associated with either of the outcomes. CONCLUSIONS MOUD receipt following endocarditis may improve important health-related outcomes in commercially insured persons with OUD.

Abstract
Background The addiction crisis is widespread, and unsafe injection practices among people who inject drugs (PWID) can lead to infective endocarditis. Methods A retrospective analysis of adult patients with definite or possible infective endocarditis admitted to a tertiary care center in Portland, Maine was performed over three-year period. Our primary objective was to examine differences in demographics, health characteristics, and health service utilization between injection drug use (IDU)-associated infective endocarditis and non-IDU infective endocarditis. The association between IDU and mortality, morbidity (defined as emergency department visits within 3 months of discharge), and cardiac surgery was examined. Bivariate and multivariate analyses were performed. A subgroup descriptive analysis of PWID was also performed to better examine substance use disorder (SUD) characteristics, treatment with medication for opioid use disorder (MOUD) and health service utilization. Results One-hundred and seven patients were included in the study, of which 39.2% (n = 42) had IDU-associated infective endocarditis. PWID were more likely to be homeless, uninsured, and lack a primary care provider. PWID were notably younger and had less documented comorbidities, however had similar in-hospital mortality rates (10% vs. 14%, p = 0.30), ED visits (50% vs. 54%, p = 0.70) and cardiac surgery (33% vs. 26%, p = 0.42) compared to those with non-IDU infective endocarditis. Ninety-day mortality was less among PWID (19.0% vs. 36.9%, p = 0.05). IDU was not associated with morbidity (adjusted odds ratio (AOR) 0.73, 95% CI 0.18–3.36), 90-day mortality (AOR 0.72, 95% CI 0.17–3.01), or cardiac surgery (AOR 0.15, 95% CI 0.03–0.69). Ninety-day mortality among PWID who received MOUD was lower (3% vs 15%, p = 0.45), as were ED visits (10% vs. 41%, p = 0.42) compared to those who did not receive MOUD. Conclusions Our results highlight existing differences in health characteristics and social determinants of health in people with IDU-associated versus non-IDU infective endocarditis. PWID had less comorbidities and were significantly younger than those with non-IDU infective endocarditis and yet still had similar rates of cardiac surgery, ED visits, and in-hospital mortality. These findings emphasize the need to deliver comprehensive health services, particularly MOUD and other harm reduction services, to this marginalized population.

Long term surgical outcomes for infective endocarditis in people who inject drugs: a systematic review and meta-analysis. BMC Infect Dis 2019; 19:918. [PMID: 31699053 PMCID: PMC6839097 DOI: 10.1186/s12879-019-4558-2] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Accepted: 10/11/2019] [Indexed: 02/18/2023] Open
Abstract
Background In recent years, the number of infective endocarditis (IE) cases associated with injection drug use has increased. Clinical guidelines suggest deferring surgery for IE in people who inject drugs (PWID) due to a concern for worse outcomes in comparison to non-injectors (non-PWID). We performed a systematic review and meta-analysis of long-term outcomes in PWID who underwent cardiac surgery and compared these outcomes to non-PWID. Methods We systematically searched for studies reported between 1965 and 2018. We used an algorithm to estimate individual patient data (eIPD) from Kaplan-Meier (KM) curves and combined it with published individual patient data (IPD) to analyze long-term outcomes after cardiac surgery for IE in PWID. Our primary outcome was survival. Secondary outcomes were reoperation and mortality at 30-days, one-, five-, and 10-years. Random effects Cox regression was used for estimating survival. Results We included 27 studies in the systematic review and 19 provided data (KM or IPD) for the meta-analysis. PWID were younger and more likely to have S. aureus than non-PWID. Survival at 30-days, one-, five-, and 10-years was 94.3, 81.0, 62.1, and 56.6% in PWID, respectively; and 96.4, 85.0, 70.3, and 63.4% in non-PWID. PWID had 47% greater hazard of death (HR 1.47, 95% CI, 1.05–2.05) and more than twice the hazard of reoperation (HR 2.37, 95% CI, 1.25–4.50) than non-PWID. Conclusion PWID had shorter survival that non-PWID. Implementing evidence-based interventions and testing new modalities are urgently needed to improve outcomes in PWID after cardiac surgery.

Abstract
Background Infective endocarditis (IE) is a lethal disease which has been changing significantly over the past decades; however, information about IE in China remains scarce. This study surveyed the changes in clinical characteristics of IE at a tertiary hospital in south China over a period of nearly 18 years. Methods Medical records with IE patients consecutively hospitalized between June 2001 and June 2018 were selected from the electronic medical records system in Nanfang Hospital of Southern Medical University. Data were divided by admission time into two groups equally: early-period group, June 2001 to December 2009 and later-period group, January 2010 to July 2018. Results A Total of 313 IE patients were included in our study. Compared with the early-period group, patients in the later-period group included fewer intravenous drug users (IVDUs), older age at onset, reduced development of pulmonary embolism, less renal dysfunction, decreased proportion of Staphylococcus aureus infection and fewer vegetations observed in the right heart by echocardiography. The later-period group also showed a higher proportion of ischemic strokes and higher proportion of positive microbiological findings compared with the early-period group. The in-hospital mortality remained about the same between the two periods and the multivariate analysis identified intravenous drug addicted, prosthetic valve endocarditis, hemorrhagic stroke, acute congestive heart failure, renal insufficiency, left-sided endocarditis, early surgical as independent predictors of in-hospital mortality. Conclusions Our study demonstrated a dramatic change in the profile of IE over a period of 18 years at a tertiary hospital in south China and presented several independent predictors of in-hospital mortality. The geographic variations observed in our study will be of important value to profile the clinical feature of China and offer the reference for clinical decisions in our region.

Abstract
BACKGROUND Fueled by the burgeoning opioid epidemic, valve surgeries for substance use disorder-related infective endocarditis (SUD-IE) are increasing. The impact of substance use disorder on postvalve replacement morbidity needs further investigation. METHODS We queried The Society of Thoracic Surgeons Adult Cardiac Surgery Database for all valve surgeries for infective endocarditis at Tufts Medical Center (2002-2016) and collected demographic and disease-related data, including timing of mortality subclassified as short-term (<6 months including operative), midterm (6 months to 5 years), and extended-term (>5 years). Patients with documentation of illicit drug use before the operation were considered to have SUD-IE. Deaths were confirmed through review of medical record and matching with the Massachusetts Vital Statistics Database. We performed univariate and multivariate proportional hazard regressions examining the impact of substance use disorder mortality in people who received a valve replacement. RESULTS In the cohort of 228 patients, 80 (35%) had SUD-IE. Eight-six people (38%) died, and overall mortality was higher in people with SUD-IE compared with non-SUD-IE (48% vs 32%, P = .025). SUD-IE was associated with a higher risk of overall mortality (adjusted hazard ratio, 2.41; 95% confidence interval, 1.38-4.20; P = .002). Although the difference between short-term or extended-term mortality was not significant, SUD-IE was associated with increased frequency of midterm mortality (53% vs 31%, P = .003). CONCLUSIONS Our data reflect high rates of postvalve surgery morbidity and mortality in people with SUD-IE at a tertiary care center. The midterm postoperative period is a vulnerable period for people with SUD-IE worthy of further investigation.

Abstract
Background There has been an increase in the prevalence of drug abuse (DA) in the national opioid epidemic. With increasing DA, there is an increased risk of infective endocarditis (IE). There are limited recent data evaluating national trends on the incidence and geographical distribution of DA‐IE. We aim to investigate those numbers as well as the determinants of outcome in this patient population. Methods and Results Hospitalized patients with a primary or secondary diagnosis of IE based on the International Classification of Diseases, Ninth and Tenth Revisions (ICD‐9, ICD‐10) were included. We described the national and geographical trends in DA‐IE. We also compared DA‐IE patients’ characteristics and outcomes to those with IE, but without associated drug abuse (non‐DA‐IE) using Poisson regression models. Incidence of DA‐IE has nearly doubled between 2002 and 2016 All US regions were affected, and the Midwest had the highest increase in DA‐IE hospitalizations (annual percent change=4.9%). Patients with DA‐IE were younger, more commonly white males, poorer, had fewer comorbidities, and were more likely to have human immunodeficiency virus, hepatitis C, concomitant alcohol abuse, and liver disease. Their length of stay was longer (9 versus 7 days; P<0.001) and were more likely to undergo cardiac surgery (7.8% versus 6.2%; P<0.001), but their inpatient mortality was lower (6.4% versus 9.1%; P<0.001). Conclusions DA‐IE is rising at an alarming rate in the United States. All regions of the United States are affected, with the Midwest having the highest increase in rate. Young‐adult, poor, white males were the most affected.

Abstract
There has been tremendous evolution in the care of cardiac surgical patients in 2018. In this article, 4 topics of considerable impact on cardiac surgical care in the current landscape are reviewed based on recent publications. The first topic reviews the recent paradigm shift to value-based payments and the potential role of bundled payments on health care and physician reimbursement. The second topic highlights the impact of the opioid crisis on cardiac surgery. The third topic demonstrates the increasing utilization and expanding role of novel percutaneous suction thrombectomy technique in the extraction of caval and right-sided intracardiac thrombi and vegetations with veno-venous bypass. The final topic reviews the current trend of minimally invasive left ventricular assist device placement. Each of these topics addresses the contemporary issues in cardiac surgery with the reasoning for evolution in our current practices in 2018.

Abstract
BACKGROUND People who inject drugs (PWID) represent a high-risk subgroup of endocarditis patients. This is highlighted by poorer post-operative outcomes in injection drug use-related infective endocarditis (IDU-IE), which is largely attributable to the increased vulnerability of prosthetic valves to re-infection. Consequently, many centres do not perform valve replacement on these patients. A parallel, but often underrecognized, component of care is the role of multidisciplinary management for individuals with IDU-IE, including perioperative addictions and psychiatric care. Consequently, surgical management options in IDU-IE remain a controversial topic. OBJECTIVES To determine the characteristics of optimal surgical and psychiatric care for individuals with IDU-IE. METHODS We conducted a narrative synthesis of the findings of literature retrieved from searches of computerized databases, hand searches, and authoritative text, organizing the findings into several key themes: clinical characteristics and factors associated with mortality in IDU-IE, alternative surgical management options, perioperative risk stratification techniques, principles of psychiatric and addictions management in IDU-IE, ethical considerations and controversies, and future research directions. RESULTS/CONCLUSIONS Managing IDU-IE involves the treatment of two comorbidities: the intra-cardiac infection and the underlying substance use disorder. Cardiac surgery represents a high-intensity intervention with appreciable risk, and the benefit it is not always clear. As patients often present acutely, it is not feasible to use drug abstinence as a prerequisite to surgery. Involvement of inpatient psychiatry and addictions teams, however, appears to be an evidence-based approach that can bridge IDU-IE patients with opioid agonist therapy in hospital and adequate outpatient treatment options for their underlying addiction upon their discharge from hospital. It is likely that a majority of these patients are not receiving optimal psychiatric management despite increasing recognition of efficacy. Further interdisciplinary studies are needed to elucidate optimal surgical and multidisciplinary protocols. BACKGROUND Infective endocarditis (IE) is an infection of the innermost lining of the heart often affecting the heart valves. Over the last few decades, the epidemiology of IE has shifted in the developed world and while it continues to be a significant cause of morbidity and mortality, there has been a significant increased incidence among persons who inject drugs (PWID). To date, well-conducted epidemiologic studies of IE among PWID have been sparse, which has limited our ability to fully characterize this disease phenomenon. To address this knowledge deficit, we conducted a narrative synthesis of the findings of literature retrieved from searches of computerized databases, hand searches, and authoritative text, and organized our findings into six key themes: clinical characteristics and factors associated with mortality in IDU-IE, alternative surgical management options, perioperative risk stratification techniques, principles of psychiatric and addictions management in IDU-IE, ethical considerations and controversies, and future research directions.

Abstract
Background Hospitalizations for individuals with injection drug use-related infective endocarditis (IDU-IE) represent an increasing portion of all patients with endocarditis. This study describes the evolving trends in demographics, clinical characteristics, rates of surgical intervention, and mortality among patients hospitalized with IE, comparing those with and without injection drug use. Methods This is a retrospective cohort study of patients admitted between January 1, 2007 to June 30, 2015 at a tertiary care center in Boston, Massachusetts. Endocarditis was defined by International Classification of Diseases, Ninth Revision code and verified by the modified Duke Criteria for IE. The clinical characteristics, microbiology, site of infection, complications of IE, and outcome were all abstracted by chart review. Rates of surgical consultation and surgical intervention within 90 days of admission were obtained, and assessment of surgical risk calculated was by EuroSCORE II (euroscore.org/calc). Subsequent hospitalizations for all causes were also reviewed. Results Injection drug use-related infective endocarditis occurred in younger patients with lower rates of diabetes, renal dysfunction, and prior cardiothoracic (CT) surgery than those without IDU. Injection drug use-related infective endocarditis was associated with higher rates of complications, CT surgery consultation, and surgery within 90 days for absolute surgical indication. Readmissions for endocarditis occurred in 20% of IDU-IE patients and 9% of those with non-IDU IE. All-cause 1-year mortality rates were similar (IDU-IE 16%, non-IDU IE 13%; P = .58). Conclusions Despite younger age, fewer medical comorbidities, and fewer prior cardiac surgeries, all-cause 1-year mortality was similar for patients after sentinel admission for IDU-IE compared with non-IDU IE. Interventions in the acute hospital setting and after discharge are needed to support patients with IDU-IE, focusing on harm reduction and treatment of addiction to reduce the unexpectedly high mortality of this young population.
