INCIDENCE AND RISK FACTORS FOR NON-DEVICE ASSOCIATED HEALTHCARE ASSOCIATED INFECTIONS
Due to current targeted surveillance programs of healthcare associated infections (HAIs), there is a paucity of research on non-device associated urinary tract infections (ND-UTIs), non-device associated pneumonia (ND-pneumonia), and non-device associated bloodstream infections (ND-BSIs). However, limited data that do exist suggest that the proportion of all HAIs that were non-device associated have increased over the last decade. Thus, the purpose of this study was to update current estimates of ND-HAI rates and their frequency relative to device associated infections, assess temporal trends, and identify potential risk factors for ND-HAIs among adult patients hospitalized at the University of North Carolina (UNC) Hospitals between 2013 – 2017. Between 2013 and 2017, the rates of ND-UTIs and ND-pneumonia remained relatively stable, and the rate of ND-BSIs increased. Additionally, ND-UTIs and ND-pneumonia cases represent the majority of infections, with almost 3 in 4 UTIs and pneumonia cases being non-device associated in 2017. One in three BSIs are non-device associated at UNC Hospitals. Females, older adults, peptic ulcer disease, paralysis, immunosuppression, opioid use, TPN, and trauma patients all had a higher risk of ND-UTI. Urinary retention, suprapubic catheters and nephrostomy tubes may also increase patient risk of ND-UTI, although estimates were imprecise. Risk factors for ND-pneumonia included male sex, older age, ICU admission, and chronic bronchitis/emphysema, congestive heart failure, paralysis, and immunosuppression. Finally, risk factors for ND-BSIs included male sex, peptic ulcer disease, paralysis, general anesthesia, opioids, and peripheral venous catheters; higher Morse Fall Risk score, beta-blockers, and UTIs (device or non-device associated) also appeared to increase patient risk. These results all suggest that specific patient and clinical characteristics may increase the risk for certain ND-HAIs, and future studies should explore targeting modifiable risk factors for potential prevention strategies.Doctor of Philosoph
Improved Survival of Patients With Extensive Burns: Trends in Patient Characteristics and Mortality Among Burn Patients in a Tertiary Care Burn Facility, 2004–2013
Classic determinants of burn mortality are age, burn size, and the presence of inhalation injury. Our objective was to describe temporal trends in patient and burn characteristics, inpatient mortality, and the relationship between these characteristics and inpatient mortality over time. All patients aged 18 years or older and admitted with burn injury, including inhalation injury only, between 2004 and 2013 were included. Adjusted Cox proportional hazards regression models were used to estimate the relationship between admit year and inpatient mortality. A total of 5540 patients were admitted between 2004 and 2013. Significant differences in sex, race/ethnicity, burn mechanisms, TBSA, inhalation injury, and inpatient mortality were observed across calendar years. Patients admitted between 2011 and 2013 were more likely to be women, non-Hispanic Caucasian, with smaller burn size, and less likely to have an inhalation injury, in comparison with patients admitted from 2004 to 2010. After controlling for patient demographics, burn mechanisms, and differential lengths of stay, no calendar year trends in inpatient mortality were detected. However, a significant decrease in inpatient mortality was observed among patients with extensive burns (≥75% TBSA) in more recent calendar years. This large, tertiary care referral burn center has maintained low inpatient mortality rates among burn patients over the past 10 years. While observed decreases in mortality during this time are largely due to changes in patient and burn characteristics, survival among patients with extensive burns has improved
Timeline of health care–associated infections and pathogens after burn injuries
Infections are an important cause of morbidity and mortality after burn injuries. Here, we describe the timeline of infections and pathogens after burns
Practice Characteristics and Job Satisfaction of Private Practice and Academic Surgeons
IMPORTANCE: Private practice and academic surgery careers vary significantly in their daily routine, compensation schemes, and definition of productivity. Data are needed regarding the practice characteristics and job satisfaction of these career paths for surgeons and trainees to make informed career decisions and to identify modifiable factors that may be associated with the health of the surgical workforce. OBJECTIVE: To obtain and compare the differences in practice characteristics and career satisfaction measures between academic and private practice surgeons. DESIGN, SETTING, AND PARTICIPANTS: In this cross-sectional survey performed from June 4 to August 1, 2018, an online survey accommodating smartphone, tablet, and desktop formats was distributed by email to 25 748 surgeons who were actively practicing fellows of the American College of Surgeons; had completed a general surgery residency or categorical fellowship in plastic, cardiothoracic, or vascular surgery; and had an active email address on file. MAIN OUTCOMES AND MEASURES: Demographic, training, and current practice characteristics were obtained, and satisfaction measures were measured on a 5-point Likert scale and compared by surgeon type. Nonresponse weights adjusted for respondent sex, age, and presence of subspecialty training between respondents and the total surveyed American College of Surgeons population. RESULTS: There were 3807 responses (15% response rate) from surgeons: 1735 academic surgeons (1390 men [80%]; median age, 53 years [interquartile range (IQR), 44-61 years]) and 1464 private practice surgeons (1276 men [87%]; median age, 56 years [IQR, 48-62 years]); 589 surgeons who reported being neither an academic surgeon nor a private practice surgeon and 19 surgeons who did not respond to questions on their practice type were excluded. Academic surgeons reported working a median of 59 hours weekly (IQR, 38-65 hours) compared with 57 hours weekly (IQR, 45-65 hours) for private practice surgeons. Academic surgeons reported more weekly hours performing nonclinical work than did private practice surgeons (24 hours [IQR, 14-38 hours] vs 9 hours [IQR, 4-17 hours]; P < .001). Academic surgeons were more likely than private practice surgeons to be satisfied with their career as a surgeon (1448 of 1706 [85%] vs 1109 of 1420 [78%]; P < .001) and their financial compensation (997 of 1703 [59%] vs 546 of 1416 [39%]; P < .001). Academic surgeons were less likely than private practice surgeons to feel that competition with other surgeons is a threat to financial security (341 of 1705 [20%] vs 559 of 1422 [39%]; P < .001) and less likely to feel that malpractice experience has decreased job satisfaction (534 of 1703 [31%] vs 686 of 1413 [49%]; P < .001). CONCLUSIONS AND RELEVANCE: This study suggests that, although overall surgeon satisfaction was high, academic surgeons reported higher career satisfaction on several measures when compared with private practice surgeons. Advocacy for private practice surgeons is important to encourage career longevity and sustain US surgeon workforce needs

Impact of Type 2 Myocardial Infarction (MI) on Hospital‐Level MI Outcomes: Implications for Quality and Public Reporting
Background: The International Classification of Diseases (ICD) coding system does not recognize type 2 myocardial infarction (MI) as a separate entity; therefore, patients with type 2 MI continue to be categorized under the general umbrella of non–ST‐segment–elevation myocardial infarction (NSTEMI). We aim to evaluate the impact of type 2 MI on hospital‐level NSTEMI metrics and discuss the implications for quality and public reporting. Methods and Results: We conducted a single‐center retrospective analysis of 1318 patients discharged with a diagnosis of NSTEMI between July 2013 and October 2014. The Third Universal Definition was used to define type 1 and type 2 MI. Weighted Kaplan–Meier curves were used to analyze risk of mortality and readmission. Overall, 1039 patients met NSTEMI criteria per the Third Universal Definition; of those, 264 (25.4%) had type 2 MI. Patients with type 2 MI were older, were more likely to have chronic kidney disease, and had lower peak troponin levels. Compared with type 1 MI patients, those with type 2 MI had higher inpatient mortality (17.4% versus 4.7%, P<0.0001) and were more likely to die from noncardiovascular causes (71.7% versus 25.0%, P<0.0001). Despite weighting for patient characteristics and discharge medications, patients with type 2 MI had higher mortality at both 30 days (risk ratio: 3.63; 95% confidence interval, 1.67–7.88) and 1 year (risk ratio: 1.98; 95% confidence interval, 1.44–2.73) after discharge. Type 2 MI was also associated with a lower 30‐day cardiovascular‐related readmission (risk ratio: 0.49; 95% confidence interval, 0.12–2.06). Conclusions: NSTEMI metrics are significantly affected by type 2 MI patients. Type 2 MI patients have distinct etiologies, are managed differently, and have higher mortality compared with patients with type 1 MI. Moving forward, it may be appropriate to exclude type 2 MI data from NSTEMI quality metrics
Endotoxin enhances respiratory effects of phthalates in adults: Results from NHANES 2005-6
Phthalates have been associated with respiratory symptoms in adults; they may enhance effects of inflammatory compounds. To assess the potential interactions of phthalates and endotoxin on respiratory and allergic symptoms in adults, we used cross-sectional information from the 1091 adults with complete data on urinary phthalates and house dust endotoxin from NHANES 2005-2006. We used multivariable logistic regression to assess whether endotoxin levels modified the association between nine phthalate metabolites and four current allergic symptoms (asthma, wheeze, hay fever, and rhinitis). Endotoxin was classified into tertiles (25EU/mg dust). Urinary phthalate and dust endotoxin levels were not correlated (r < |0.02|). Under low endotoxin conditions, no associations between phthalates and respiratory outcomes were observed. Under medium or high endotoxin conditions, exposure-response relationships were observed between specific phthalates and wheeze and asthma. For wheeze, three phthalates (mono-benzyl phthalate (MBzP), mono(carboxyoctyl) phthalate (MCOP), and di-ethylhexyl phthalate (DEHP) had significant interactions with endotoxin); for asthma, two phthalates (MCOP and mono(carboxyoctyl) phthalate (MCNP)) had significant interactions. Endotoxin did not modify the associations between phthalates and hay fever or rhinitis. These results are consistent with the hypothesis that endotoxin enhances the respiratory toxicity of phthalates; however this cross-sectional study cannot address key temporal issues. The lack of an association between wheeze or asthma and phthalates when endotoxin exposure was low suggests that phthalates alone may not increase these symptoms

COVID-19 vaccination willingness and uptake among low-income Black/African American, Latino, and White adults living in the U.S
The purpose of this study was to assess differences in COVID-19 vaccine willingness and uptake between low-income and non-low-income adults and across race-ethnicity. We utilized data from the COVID-19's Unequal Racial Burden online survey, which included baseline (12/17/2020-2/11/2021) and 6-month follow-up (8/13/2021-9/9/2021) surveys. The sample included 1,500 Black/African American, Latino, and White low-income adults living in the U.S. (N = 500 each). A non-low-income cohort was created for comparison (n = 1,188). Multinomial logistic regression was used to assess differences in vaccine willingness and uptake between low-income and non-low-income adults, as well as across race-ethnicity (low-income adults only). Only low-income White adults were less likely to be vaccinated compared to their non-low-income counterparts (extremely willing vs. not at all: OR = 0.58, 95% CI = 0.39-0.86); low-income Black/African American and Latino adults were just as willing or more willing to vaccinate. At follow-up, only 30.2% of low-income adults who reported being unwilling at baseline were vaccinated at follow-up. White low-income adults (63.6%) appeared less likely to be vaccinated, compared to non-low-income White adults (80.9%), low-income Black/African American (70.7%), and low-income Latino adults (72.4%). Distrust in the government (46.6), drug companies (44.5%), and vaccine contents (52.1%) were common among those unwilling to vaccinate. This prospective study among a diverse sample of low-income adults found that low-income White adults were less willing and less likely to vaccinate than their non-low-income counterparts, but this difference was not observed for Black/African American or Latino adults. Distrust and misinformation were prevalent among those who remained unvaccinated at follow-up
