Strategies for developing a successful career in academic medicine.

Academic medicine provides physicians an opportunity for long-term career satisfaction and fulfillment. However, despite the potential for great reward, academic careers can be challenging. To better define approaches to successfully navigate academic medicine, the Southern Society for Clinical Investigation sponsored a workshop titled 'Successful Careers in Academic Medicine' during the 2023 Southern Regional Meeting held in New Orleans; the critical elements of which are highlighted in the following summary. Participants discussed the benefits of an academic career, summarized strategies for negotiating a job, listed critical tools for career development, and discussed key concepts about planning and navigating the academic medicine promotion process. The information provides a roadmap for physicians to develop successful careers in academic medicine.

Implementation of contact precautions for multidrug-resistant organisms in the post-COVID-19 pandemic era: An updated national Emerging Infections Network (EIN) survey.

OBJECTIVE: To understand how healthcare facilities employ contact precautions for patients with multidrug-resistant organisms (MDROs) in the post-coronavirus disease 2019 (COVID-19) era and explore changes since 2014. DESIGN: Cross-sectional survey. PARTICIPANTS: Emerging Infections Network (EIN) physicians involved in infection prevention or hospital epidemiology. METHODS: In September 2022, we sent via email an 8-question survey on contact precautions and adjunctive measures to reduce MDRO transmission in inpatient facilities. We also asked about changes since the COVID-19 pandemic. We used descriptive statistics to summarize data and compared results to a similar survey administered in 2014. RESULTS: Of 708 EIN members, 283 (40%) responded to the survey and 201 reported working in infection prevention. A majority of facilities (66% and 69%) routinely use contact precautions for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) respectively, compared to 93% and 92% in 2014. Nearly all (>90%) use contact precautions for Candida auris, carbapenem-resistant Enterobacterales (CRE), and carbapenem-resistant Acinetobacter baumannii. More variability was reported for carbapenem-resistant Pseudomonas aeruginosa and extended-spectrum ß-lactamase-producing gram-negative organisms. Compared to 2014, fewer hospitals perform active surveillance for MRSA and VRE. Overall, 90% of facilities used chlorhexidine gluconate bathing in all or select inpatients, and 53% used ultraviolet light or hydrogen peroxide vapor disinfection at discharge. Many respondents (44%) reported changes to contact precautions since COVID-19 that remain in place. CONCLUSIONS: Heterogeneity exists in the use of transmission-based precautions and adjunctive infection prevention measures aimed at reducing MDRO transmission. This variation reflects a need for updated and specific guidance, as well as further research on the use of contact precautions in healthcare facilities.

The impact of COVID-19 on multidrug-resistant organisms causing healthcare-associated infections: a narrative review.

Coronavirus disease 2019 (COVID-19) changed healthcare across the world. With this change came an increase in healthcare-associated infections (HAIs) and a concerning concurrent proliferation of MDR organisms (MDROs). In this narrative review, we describe the impact of COVID-19 on HAIs and MDROs, describe potential causes of these changes, and discuss future directions to combat the observed rise in rates of HAIs and MDRO infections.

Poor outcomes in both infection and colonization with carbapenem-resistant Enterobacterales.

OBJECTIVES: To describe the epidemiology of patients with nonintestinal carbapenem-resistant Enterobacterales (CRE) colonization and to compare clinical outcomes of these patients to those with CRE infection. DESIGN: A secondary analysis of Consortium on Resistance Against Carbapenems in Klebsiella and other Enterobacteriaceae 2 (CRACKLE-2), a prospective observational cohort. SETTING: A total of 49 US short-term acute-care hospitals. PATIENTS: Patients hospitalized with CRE isolated from clinical cultures, April, 30, 2016, through August 31, 2017. METHODS: We described characteristics of patients in CRACKLE-2 with nonintestinal CRE colonization and assessed the impact of site of colonization on clinical outcomes. We then compared outcomes of patients defined as having nonintestinal CRE colonization to all those defined as having infection. The primary outcome was a desirability of outcome ranking (DOOR) at 30 days. Secondary outcomes were 30-day mortality and 90-day readmission. RESULTS: Of 547 patients with nonintestinal CRE colonization, 275 (50%) were from the urinary tract, 201 (37%) were from the respiratory tract, and 71 (13%) were from a wound. Patients with urinary tract colonization were more likely to have a more desirable clinical outcome at 30 days than those with respiratory tract colonization, with a DOOR probability of better outcome of 61% (95% confidence interval [CI], 53%-71%). When compared to 255 patients with CRE infection, patients with CRE colonization had a similar overall clinical outcome, as well as 30-day mortality and 90-day readmission rates when analyzed in aggregate or by culture site. Sensitivity analyses demonstrated similar results using different definitions of infection. CONCLUSIONS: Patients with nonintestinal CRE colonization had outcomes similar to those with CRE infection. Clinical outcomes may be influenced more by culture site than classification as "colonized" or "infected."

Healthcare worker mental models of patient care tasks in the context of infection prevention and control.

OBJECTIVE: Understanding the cognitive determinants of healthcare worker (HCW) behavior is important for improving the use of infection prevention and control (IPC) practices. Given a patient requiring only standard precautions, we examined the dimensions along which different populations of HCWs cognitively organize patient care tasks (ie, their mental models). DESIGN: HCWs read a description of a patient and then rated the similarities of 25 patient care tasks from an infection prevention perspective. Using multidimensional scaling, we identified the dimensions (ie, characteristics of tasks) underlying these ratings and the salience of each dimension to HCWs. SETTING: Adult inpatient hospitals across an academic hospital network. PARTICIPANTS: In total, 40 HCWs, comprising infection preventionists and nurses from intensive care units, emergency departments, and medical-surgical floors rated the similarity of tasks. To identify the meaning of each dimension, another 6 nurses rated each task in terms of specific characteristics of tasks. RESULTS: Each HCW population perceived patient care tasks to vary along 3 common dimensions; most salient was the perceived magnitude of infection risk to the patient in a task, followed by the perceived dirtiness and risk of HCW exposure to body fluids, and lastly, the relative importance of a task for preventing versus controlling an infection in a patient. CONCLUSIONS: For a patient requiring only standard precautions, different populations of HCWs have similar mental models of how various patient care tasks relate to IPC. Techniques for eliciting mental models open new avenues for understanding and ultimately modifying the cognitive determinants of IPC behaviors.

Occupational risk factors for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection among healthcare personnel: A cross-sectional analysis of subjects enrolled in the COVID-19 Prevention in Emory Healthcare Personnel (COPE) study.

Among 353 healthcare personnel in a longitudinal cohort in 4 hospitals in Atlanta, Georgia (May-June 2020), 23 (6.5%) had severe acute respiratory coronavirus virus 2 (SARS-CoV-2) antibodies. Spending >50% of a typical shift at the bedside (OR, 3.4; 95% CI, 1.2-10.5) and black race (OR, 8.4; 95% CI, 2.7-27.4) were associated with SARS-CoV-2 seropositivity.

Occupational risk factors for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection among healthcare personnel: A 6-month prospective analysis of the COVID-19 Prevention in Emory Healthcare Personnel (COPE) Study.

OBJECTIVES: To determine the incidence of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection among healthcare personnel (HCP) and to assess occupational risks for SARS-CoV-2 infection. DESIGN: Prospective cohort of healthcare personnel (HCP) followed for 6 months from May through December 2020. SETTING: Large academic healthcare system including 4 hospitals and affiliated clinics in Atlanta, Georgia. PARTICIPANTS: HCP, including those with and without direct patient-care activities, working during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Incident SARS-CoV-2 infections were determined through serologic testing for SARS-CoV-2 IgG at enrollment, at 3 months, and at 6 months. HCP completed monthly surveys regarding occupational activities. Multivariable logistic regression was used to identify occupational factors that increased the risk of SARS-CoV-2 infection. RESULTS: Of the 304 evaluable HCP that were seronegative at enrollment, 26 (9%) seroconverted for SARS-CoV-2 IgG by 6 months. Overall, 219 participants (73%) self-identified as White race, 119 (40%) were nurses, and 121 (40%) worked on inpatient medical-surgical floors. In a multivariable analysis, HCP who identified as Black race were more likely to seroconvert than HCP who identified as White (odds ratio, 4.5; 95% confidence interval, 1.3-14.2). Increased risk for SARS-CoV-2 infection was not identified for any occupational activity, including spending >50% of a typical shift at a patient's bedside, working in a COVID-19 unit, or performing or being present for aerosol-generating procedures (AGPs). CONCLUSIONS: In our study cohort of HCP working in an academic healthcare system, <10% had evidence of SARS-CoV-2 infection over 6 months. No specific occupational activities were identified as increasing risk for SARS-CoV-2 infection.

Carbapenem-resistant Enterobacterales bacteriuria and subsequent bacteremia: A population-based study.

OBJECTIVE: To describe the epidemiology of carbapenem-resistant Enterobacterales (CRE) bacteriuria and to determine whether urinary catheters increase the risk of subsequent CRE bacteremia. DESIGN: Using active population- and laboratory-based surveillance we described a cohort of patients with incident CRE bacteriuria and identified risk factors for developing CRE bacteremia within 1 year. SETTING: The study was conducted among the 8 counties of Georgia Health District 3 (HD3) in Atlanta, Georgia. PATIENTS: Residents of HD3 with CRE first identified in urine between 2012 and 2017. RESULTS: We identified 464 patients with CRE bacteriuria (mean yearly incidence, 1.96 cases per 100,000 population). Of 425 with chart review, most had a urinary catheter (56%), and many resided in long-term care facilities (48%), had a Charlson comorbidity index >3 (38%) or a decubitus ulcer (37%). 21 patients (5%) developed CRE bacteremia with the same organism within 1 year. Risk factors for subsequent bacteremia included presence of a urinary catheter (odds ratio [OR], 8.0; 95% confidence interval [CI], 1.8-34.9), central venous catheter (OR, 4.3; 95% CI, 1.7-10.6) or another indwelling device (OR, 4.3; 95% CI, 1.6-11.4), urine culture obtained as an inpatient (OR, 5.7; 95% CI, 1.3-25.9), and being in the ICU in the week prior to urine culture (OR, 2.9; 95% CI, 1.1-7.8). In a multivariable analysis, urinary catheter increased the risk of CRE bacteremia (OR, 5.3; 95% CI, 1.2-23.6). CONCLUSIONS: In patients with CRE bacteriuria, urinary catheters increase the risk of CRE bacteremia. Future interventions should aim to reduce inappropriate insertion and early removal of urinary catheters.

Sustained decrease in urine culture utilization after implementing a reflex urine culture intervention: A multicenter quasi-experimental study.

Accurately diagnosing urinary tract infections (UTIs) in hospitalized patients remains challenging, requiring correlation of frequently nonspecific symptoms and laboratory findings. Urine cultures (UCs) are often ordered indiscriminately, especially in patients with urinary catheters, despite the Infectious Diseases Society of America guidelines recommending against routine screening for asymptomatic bacteriuria (ASB).1,2 Positive UCs can be difficult for providers to ignore, leading to unnecessary antibiotic treatment of ASB.2,3 Using diagnostic stewardship to limit UCs to situations with a positive urinalysis (UA) can reduce inappropriate UCs since the absence of pyuria suggests the absence of infection.4-6 We assessed the impact of the implementation of a UA with reflex to UC algorithm ("reflex intervention") on UC ordering practices, diagnostic efficiency, and UTIs using a quasi-experimental design.

The impact of an electronic medical record nudge on reducing testing for hospital-onset Clostridioides difficile infection.

OBJECTIVE: To determine the effect of an electronic medical record (EMR) nudge at reducing total and inappropriate orders testing for hospital-onset Clostridioides difficile infection (HO-CDI). DESIGN: An interrupted time series analysis of HO-CDI orders 2 years before and 2 years after the implementation of an EMR intervention designed to reduce inappropriate HO-CDI testing. Orders for C. difficile testing were considered inappropriate if the patient had received a laxative or stool softener in the previous 24 hours. SETTING: Four hospitals in an academic healthcare network. PATIENTS: All patients with a C. difficile order after hospital day 3. INTERVENTION: Orders for C. difficile testing in patients administered a laxative or stool softener in <24 hours triggered an EMR alert defaulting to cancellation of the order ("nudge"). RESULTS: Of the 17,694 HO-CDI orders, 7% were inappropriate (8% prentervention vs 6% postintervention; P < .001). Monthly HO-CDI orders decreased by 21% postintervention (level-change rate ratio [RR], 0.79; 95% confidence interval [CI], 0.73-0.86), and the rate continued to decrease (postintervention trend change RR, 0.99; 95% CI, 0.98-1.00). The intervention was not associated with a level change in inappropriate HO-CDI orders (RR, 0.80; 95% CI, 0.61-1.05), but the postintervention inappropriate order rate decreased over time (RR, 0.95; 95% CI, 0.93-0.97). CONCLUSION: An EMR nudge to minimize inappropriate ordering for C. difficile was effective at reducing HO-CDI orders, and likely contributed to decreasing the inappropriate HO-CDI order rate after the intervention.
