Project description:The Centers for Disease Control and Prevention considers carbapenem-resistant Enterobacteriaceae (CRE) an urgent public health threat; however, its economic burden is unknown.We developed a CRE clinical and economics outcomes model to determine the cost of CRE infection from the hospital, third-party payer, and societal, perspectives and to evaluate the health and economic burden of CRE to the USA.Depending on the infection type, the median cost of a single CRE infection can range from $22 484 to $66 031 for hospitals, $10 440 to $31 621 for third-party payers, and $37 778 to $83 512 for society. An infection incidence of 2.93 per 100 000 population in the USA (9418 infections) would cost hospitals $275 million (95% CR $217-334 million), third-party payers $147 million (95% CR $129-172 million), and society $553 million (95% CR $303-1593 million) with a 25% attributable mortality, and would result in the loss of 8841 (95% CR 5805-12 420) quality-adjusted life years. An incidence of 15 per 100 000 (48 213 infections) would cost hospitals $1.4 billion (95% CR $1.1-1.7 billion), third-party payers $0.8 billion (95% CR $0.6-0.8 billion), and society $2.8 billion (95% CR $1.6-8.2 billion), and result in the loss of 45 261 quality-adjusted life years.The cost of CRE is higher than the annual cost of many chronic diseases and of many acute diseases. Costs rise proportionally with the incidence of CRE, increasing by 2.0 times, 3.4 times, and 5.1 times for incidence rates of 6, 10, and 15 per 100 000 persons.

Project description:BackgroundAcinetobacter baumannii is a common cause of healthcare-associated infections. Carbapenem-resistant (CR) A baumannii is a significant threat globally. We used a large reference laboratory database to study the epidemiology of A baumannii in children in the United States.MethodsAntimicrobial susceptibility data from The Surveillance Network were used to phenotypically identify antibiotic resistance in A baumannii isolates in children 1-17 years of age between January 1999 and July 2012. Logistic regression analysis was used to calculate trends in the prevalence of antibiotic resistance in A baumannii. Isolates from infants (<1 year old) were excluded.ResultsThe crude proportion of cephalosporin-resistant (CephR) A baumannii increased from 13.2% in 1999 to 23.4% in 2012 with a peak of 32.5% in 2008, and the proportion of CR A baumannii increased from 0.6% in 1999 to 6.1% in 2012 with a peak of 12.7% in 2008. From 1999 to 2012, the proportion of CephR and CR A baumannii increased each year by 3% and 8%, respectively (CephR odds ratio [OR] = 1.03, 95% confidence interval [CI], 1.01-1.04; CR OR = 1.08, 95% CI, 1.05-1.12); however, after 2008, a significant decrease in trend was observed (CephR OR = 0.78, 95% CI, 0.71-0.87; CR OR = 0.73, 95% CI, 0.62-0.86), but resistance remained higher than baseline (1999).ConclusionsOverall, between 1999 and 2012, CephR and CR A baumannii isolates increased in children; however, a decreasing trend was observed after 2008.There is a need for ongoing surveillance of A baumannii infections and continued assessment of effective prevention strategies in vulnerable populations.

Project description:Carbapenem-resistant Enterobacteriaceae (CRE) are an emerging global public health threat. Infections due to CRE are associated with significant morbidity and mortality. Few therapeutic options are available for treatment of these infections, and optimal antibiotic treatment regimens are unclear. Along with the rapidly increasing prevalence of CRE in the USA and worldwide, several studies have described the epidemiology of CRE in the adult population. While CRE are now also reported sporadically in children, there is a significant lack of data on the epidemiology, risk factors, treatment, and outcomes in this population. This article provides a comprehensive review of what is known to date about CRE, including clinical and molecular epidemiology, microbiologic diagnosis, antibiotic treatment options, and outcomes. In particular, this review will focus on the available data on CRE in the pediatric population.

Project description:Background:Carbapenem-resistant Enterobacteriaceae (CRE) pose an urgent public health threat in the United States. An important step in planning and monitoring a national response to CRE is understanding its epidemiology and associated outcomes. We conducted a systematic literature review of studies that investigated incidence and outcomes of CRE infection in the US. Methods:We performed searches in MEDLINE via Ovid, CDSR, DARE, CENTRAL, NHS EED, Scopus, and Web of Science for articles published from 1/1/2000 to 2/1/2016 about the incidence and outcomes of CRE at US sites. Results:Five studies evaluated incidence, but many used differing definitions for cases. Across the entire US population, the reported incidence of CRE was 0.3-2.93 infections per 100,000 person-years. Infection rates were highest in long-term acute-care (LTAC) hospitals. There was insufficient data to assess trends in infection rates over time. Four studies evaluated outcomes. Mortality was higher in CRE patients in some but not all studies. Conclusion:While the incidence of CRE infections in the United States remains low on a national level, the incidence is highest in LTACs. Studies assessing outcomes in CRE-infected patients are limited in number, small in size, and have reached conflicting results. Future research should measure a variety of clinical outcomes and adequately adjust for confounders to better assess the full burden of CRE.

Project description:Infections due to carbapenem-resistant Enterobacteriaceae (CRE) are increasingly prevalent in children and are associated with poor clinical outcomes. Optimal treatment strategies for CRE infections continue to evolve. A lack of pediatric-specific comparative effectiveness data, uncertain pediatric dosing regimens for several agents, and a relative lack of new antibiotics with pediatric indications approved by the US Food and Drug Administration (FDA) collectively present unique challenges for children. In this review, we provide a framework for antibiotic treatment of CRE infections in children, highlighting relevant microbiologic considerations and summarizing available data related to the evaluation of FDA-approved antibiotics (as of September 2019) with CRE activity, including carbapenems, ceftazidime-avibactam, meropenem-vaborbactam, imipenem/cilastatin-relebactam, polymyxins, tigecycline, eravacycline, and plazomicin.

Project description:Infections caused by carbapenem-resistant Enterobacteriaceae (CRE) are on the rise worldwide but are not well described in pediatric populations. This study characterizes the clinical, phenotypic and genotypic characteristics of CRE infections at a free-standing US children's hospital.CRE were defined as any clinical Enterobacteriaceae isolate non-susceptible to either imipenem or meropenem and resistant to ceftriaxone, cefotaxime and ceftazidime determined by routine antimicrobial susceptibility testing. The modified Hodge test was performed to screen for the production of carbapenemase. Clinical data were reviewed, and molecular characterization of phylogenetic and resistance-associated traits was performed.CRE isolates were recovered from sterile and non-sterile sites in 10 patients, 6 weeks to 24 years of age, between 2011 and 2013. Co-morbidities included hematologic, genetic and urologic abnormalities. Two patients had traveled abroad (India, Lebanon) before CRE recovery. Carbapenemase determinants were detected in 5 cases, including KPC-3 in 2 Klebsiella pneumoniae (ST258 and ST18) and 1 Escherichia coli (ST131), and NDM-1 in 1 K. pneumoniae (ST37) and 1 E. coli (ST101) isolate. Additional resistance determinants were detected, including CTX-M-15, SHV-11, TEM-1, CMY-2, CMY-4 and CMY-42. Four patients died, including 2 of 3 patients with CRE bacteremia. There was no evidence of epidemiologic or molecular relatedness between any 2 cases.This report documents the appearance of highly resistant Gram-negative pathogens in a vulnerable patient population at a pediatric tertiary referral center in a major US metropolitan area. Detailed understanding of the distribution and spread of CRE is essential for the timely detection and containment of these perilous pathogens.

Project description:BackgroundPolymyxins (colistin, polymyxin B) have been first-line antibiotics against carbapenem-resistant Enterobacteriaceae (CRE) infections. New anti-CRE antibiotics (ceftazidime-avibactam, meropenem-vaborbactam, plazomicin) improve outcomes in CRE-infected patients and reduce toxicity compared with polymyxins. It is unclear how widely polymyxins and newer agents are used to treat CRE infections.MethodsWe conducted an online survey of US hospital-based pharmacists to determine antibiotic positioning against CRE infections. Numbers of all infections and CRE infections treated with different antibiotics in the United States were determined using IQVIA prescription data and Driving Re-investment in Research and Development and Responsible Antibiotic Use (DRIVE-AB) estimates of CRE infections.ResultsCeftazidime-avibactam, meropenem-vaborbactam, or plazomicin were positioned as first-line agents against CRE pneumonia, bacteremia, intra-abdominal infections, and urinary tract infections at 87%, 90%, 83%, and 56% of surveyed US hospitals, respectively. From February 2018 to January 2019, an estimated 9437 and 7941 CRE infections were treated with an intravenous polymyxin or new agent, respectively; these figures represented ~28% (range, 19%-50%) and ~23% (range, 16%-42%) of CRE infections in the United States. Use of ceftazidime-avibactam, meropenem-vaborbactam, or plazomicin exceeded that of intravenous polymyxins against CRE infections as of December 2018. Currently, the new drugs are estimated to treat 35% (23% to 62%) of CRE infections in which they were expected to be first-line agents.ConclusionsNew anti-CRE agents recently surpassed intravenous polymyxins as treatment for CRE infections, but use is less than expected from their positioning at US hospitals. Research on behavioral and economic factors that impact use of new antibiotics is needed, as are financial "pull" incentives that promote an economically viable marketplace.

Project description:BACKGROUND:Millions of Americans live in the US territories, but health outcomes and payments among Medicare beneficiaries in these territories are not well characterized. METHODS:Among Fee-for-Service Medicare beneficiaries aged 65 years and older hospitalized between 1999 and 2012 for acute myocardial infarction (AMI), heart failure (HF), and pneumonia, we compared hospitalization rates, patient outcomes, and inpatient payments in the territories and states. RESULTS:Over 14 years, there were 4,350,813 unique beneficiaries in the territories and 402,902,615 in the states. Hospitalization rates for AMI, HF, and pneumonia declined overall and did not differ significantly. However, 30-day mortality rates were higher in the territories for all 3 conditions: in the most recent time period (2008-2012), the adjusted odds of 30-day mortality were 1.34 [95% confidence interval (CI), 1.21-1.48], 1.24 (95% CI, 1.12-1.37), and 1.85 (95% CI, 1.71-2.00) for AMI, HF, and pneumonia, respectively; adjusted odds of 1-year mortality were also higher. In the most recent study period, inflation-adjusted Medicare in-patient payments, in 2012 dollars, were lower in the territories than the states, at $9234 less (61% lower than states), $4479 less (50% lower), and $4403 less (39% lower) for AMI, HF, and pneumonia hospitalizations, respectively (P<0.001 for all). CONCLUSIONS AND RELEVANCE:Among Medicare Fee-for-Service beneficiaries, in 2008-2012 mortality rates were higher, or not significantly different, and hospital reimbursements were lower for patients hospitalized with AMI, HF, and pneumonia in the territories. Improvement of health care and policies in the territories is critical to ensure health equity for all Americans.
