Candida auris screening practices at healthcare facilities in the United States: An Emerging Infections Network survey.

We surveyed members of the Emerging Infections Network about Candida auris screening practices at US healthcare facilities. Only 37% of respondents reported conducting screening; among these, 75% reported detection of at least 1 C. auris case in the last year. Increased screening could improve C. auris detection and prevent spread.

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.

What do infectious disease specialists think about managing long COVID?

This survey of infectious disease providers on long COVID care revealed a lack of familiarity with existing resources, a sentiment of missing guidelines, and scarcity of dedicated care centers. The low response rate suggests that infectious disease specialists do not consider themselves as the primary providers of long COVID care.

Antifungal Therapeutic Drug Monitoring Practices: Results of an Emerging Infections Network Survey.

In a survey of 523 infectious disease specialists, a moderate to high percentage reported using any antifungal therapeutic drug monitoring (TDM) during itraconazole (72%), posaconazole (72%), and voriconazole (90%) treatment, and a low to moderate percentage reported using any antifungal TDM during prophylaxis (32%, 55%, and 65%, respectively). Long turnaround times for send-out TDM testing and logistical difficulties were frequent barriers.

Harm Reduction: A Missing Piece to the Holistic Care of Patients Who Inject Drugs.

Background: The rise in injection drug use (IDU) has led to an increase in drug-related infections. Harm reduction is an important strategy for preventing infections among people who inject drugs (PWID). We attempted to evaluate the harm reduction counseling that infectious diseases physicians provide to PWID presenting with infections. Methods: An electronic survey was distributed to physician members of the Emerging Infections Network to inquire about practices used when caring for patients with IDU-related infections. Results: In total, 534 ID physicians responded to the survey. Of those, 375 (70%) reported routinely caring for PWID. Most respondents report screening for human immunodeficiency virus (HIV) and viral hepatitis (98%) and discussing the risk of these infections (87%); 63% prescribe immunization against viral hepatitis, and 45% discuss HIV preexposure prophylaxis (PrEP). However, 55% of respondents (n = 205) reported not counseling patients on safer injection strategies. Common reasons for not counseling included limited time and a desire to emphasize antibiotic therapy/medical issues (62%), lack of training (55%), and believing that it would be better addressed by other services (47%). Among respondents who reported counseling PWID, most recommended abstinence from IDU (72%), handwashing and skin cleansing before injection (62%), and safe disposal of needles/drug equipment used before admission (54%). Conclusions: Almost all ID physicians report screening PWID for HIV and viral hepatitis and discussing the risks of these infections. Despite frequently encountering PWID, fewer than half of ID physicians provide safer injection advice. Opportunities exist to standardize harm reduction education, emphasizing safer injection practices in conjunction with other strategies to prevent infections (eg, HIV PrEP or hepatitis A virus/hepatitis B virus vaccination).

Perspectives on Diagnosis and Management of All-Cause Encephalitis: A National Survey of Adult Infectious Diseases Physicians.

Background: Encephalitis is widely recognized as a challenging condition to diagnose and manage. The care of patients with encephalitis typically involves multiple disciplines, including neurologists and infectious disease (ID) physicians. Our objective was to describe the perspectives and needs of ID physicians regarding encephalitis, using a cross-sectional questionnaire survey. Methods: We performed a survey among physician members of the Infectious Diseases Society of America's (IDSA) Emerging Infections Network (EIN). Results: Response rate was 33% (480 among 1472 active EIN physician members). More than 75% of respondents reported caring for patients with suspected encephalitis. Although one-third were involved in the care of multiple patients with autoimmune encephalitis (AE) annually, comfort in diagnosing and managing encephalitis, and in particular AE, was low. Experience with advanced diagnostic tools was variable, as were approaches toward deployment of such tools. Respondents noted that training could be improved by incorporating a multidisciplinary approach taking advantage of online and virtual platforms. ID physicians report a heavy reliance on the 2008 IDSA guidelines for the management of encephalitis, and indicated strong support for a formal update. Conclusions: ID physicians play an important role in the diagnosis and management of all-cause encephalitis. Despite exposure to AE, few ID physicians are comfortable in recognizing, diagnosing, and treating AE. Moreover, comfort with and use of advanced diagnostic tools for infectious encephalitis was highly variable. Training in encephalitis should include a focus on use and stewardship of advanced diagnostic tools and on collaborative approaches with neurologists and other practitioners on mechanisms and clinical presentations of AE. There is a need for a formal update of 2008 guidelines on the management of encephalitis.

Use of Severe Acute Respiratory Syndrome Coronavirus 2 Antibody Tests by US Infectious Disease Physicians: Results of an Emerging Infections Network Survey, March 2022.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody tests have had limited recommended clinical application during the coronavirus disease 2019 (COVID-19) pandemic. To inform clinical practice, an understanding is needed of current perspectives of United States-based infectious disease (ID) physicians on the use, interpretation, and need for SARS-CoV-2 antibody tests. Methods: In March 2022, members of the Emerging Infections Network (EIN), a national network of practicing ID physicians, were surveyed on types of SARS-CoV-2 antibody assays ordered, interpretation of test results, and clinical scenarios for which antibody tests were considered. Results: Of 1867 active EIN members, 747 (40%) responded. Among the 583 who managed or consulted on COVID-19 patients, a majority (434/583 [75%]) had ordered SARS-CoV-2 antibody tests and were comfortable interpreting positive (452/578 [78%]) and negative (405/562 [72%]) results. Antibody tests were used for diagnosing post-COVID-19 conditions (61%), identifying prior SARS-CoV-2 infection (60%), and differentiating prior infection and response to COVID-19 vaccination (37%). Less than a third of respondents had used antibody tests to assess need for additional vaccines or risk stratification. Lack of sufficient evidence for use and nonstandardized assays were among the most common barriers for ordering tests. Respondents indicated that statements from professional societies and government agencies would influence their decision to order SARS-CoV-2 antibody tests for clinical decision making. Conclusions: Practicing ID physicians are using SARS-CoV-2 antibody tests, and there is an unmet need for clarifying the appropriate use of these tests in clinical practice. Professional societies and US government agencies can support clinicians in the community through the creation of appropriate guidance.

Defining Variability in Evaluation and Management of Children with Chronic Osteomyelitis.

Pediatric chronic osteomyelitis is a rare, debilitating condition lacking management guidelines. In a national survey of 162 pediatric infectious disease physicians through the Emerging Infections Network, tremendous variability in diagnostic approaches and management was noted, highlighting a need for a prospective study to better define the spectrum of pathogens and disease.

Exploring unintended consequences of adult antimicrobial stewardship programs: An Emerging Infections Network survey.

We performed a survey of adult infectious diseases (ID) physicians to explore unintended consequences of antimicrobial stewardship programs (ASP). ID physicians worried about disagreement with colleagues, provider autonomy, and remote recommendations. Non-ASP ID physicians expressed more concern regarding ASPs focus on costs, provider efficiency, and unintended consequences of ASP guidance.

Pediatric infectious disease physician perceptions of antimicrobial stewardship programs.

Pediatric antimicrobial stewardship programs (ASPs) improve antibiotic use for hospitalized children. Prescriber surveys indicate acceptance of ASPs, but data on infectious diseases (ID) physician opinions of ASPs are lacking. We conducted a survey of pediatric ID physicians, ASP and non-ASP, and their perceptions of ASP practices and outcomes.

Management of Histoplasmosis by Infectious Disease Physicians.

Background: The Infectious Diseases Society of America (IDSA) guidelines for the management of histoplasmosis were last revised 15 years ago. Since those guidelines were compiled, new antifungal treatment options have been developed. Furthermore, the ongoing development of immunomodulatory therapies has increased the population at increased risk to develop histoplasmosis. Methods: An electronic survey about the management practices of histoplasmosis was distributed to the adult infectious disease (ID) physician members of the IDSA's Emerging Infections Network. Results: The survey response rate was 37% (551/1477). Only 46% (253/551) of respondents reported seeing patients with histoplasmosis. Regions considered endemic had 82% (158/193) of physicians report seeing patients with histoplasmosis compared to 27% (95/358) of physicians in regions not classically considered endemic (P < 0.001). Most ID physicians follow IDSA treatment guidelines recommending itraconazole for acute pulmonary (189/253 [75%]), mild-moderate disseminated (189/253 [75%]), and as step-down therapy for severe disseminated histoplasmosis with (232/253 [92%]) and without (145/253 [57%]) central nervous system involvement. There were no consensus recommendations observed for survey questions regarding immunocompromised patients. Conclusions: Though there are increased reports of histoplasmosis diagnoses outside regions classically considered endemic, a majority of ID physicians reported not seeing patients with histoplasmosis. Most respondents reported adherence to IDSA guidelines recommending itraconazole in each clinical situation. New histoplasmosis guidelines need to reflect the growing need for updated general guidance, particularly for immunocompromised populations.

Approaches to healthcare personnel exemption requests from coronavirus disease 2019 (COVID-19) vaccination: Results of a national survey.

OBJECTIVE: Although a growing number of healthcare facilities are implementing healthcare personnel (HCP) coronavirus disease 2019 (COVID-19) vaccination requirements, vaccine exemption request management as a part of such programs is not well described. DESIGN: Cross-sectional survey. PARTICIPANTS: Infectious disease (ID) physician members of the Emerging Infections Network with infection prevention or hospital epidemiology responsibilities. METHODS: Eligible persons were sent a web-based survey focused on hospital plans and practices around exemption allowances from HCP COVID-19 vaccine requirements. RESULTS: Of the 695 ID physicians surveyed, 263 (38%) responded. Overall, 160 respondent institutions (92%) allowed medical exemptions, whereas 132 (76%) allowed religious exemptions. In contrast, only 14% (n = 24) allowed deeply held personal belief exemptions. The types of medical exemptions allowed varied considerably across facilities, with allergic reactions to the vaccine or its components accepted by 145 facilities (84%). For selected scenarios commonly used as the basis for religious and deeply held personal belief exemption requests, 144 institutions (83%) would not approve exemptions focused on concerns regarding right of consent or violations of freedom of personal choice, and 140 institutions (81%) would not approve exemptions focused on introducing foreign substances into one's body or the sanctity of the body. Most respondents noted plans for additional infection prevention interventions for HCP who received an exemption for COVID-19 vaccination. CONCLUSIONS: Although many respondent institutions allowed exemptions from HCP COVID-19 vaccination requirements, the types of exemptions allowed and how the exemption programs were structured varied widely.

Perceptions of risk of SARS-CoV-2 transmission in social and educational activities by infectious diseases and general pediatric healthcare providers, a pre-vaccine risk perception cross-sectional survey.

BACKGROUND: The perception of the transmission risks of SARS-CoV-2 in social and educational settings by US healthcare providers have not been previously quantified. METHODS: Respondents completed an online survey between September and October 2020 to estimate the risk of SARS-CoV-2 transmission on a scale of 0-10 for different social and educational activities prior to the availability of the SARS-CoV-2 vaccines. Demographic information and experiences during the pandemic were also collected. The risk assessment was emailed to three listservs of healthcare providers, including national listservs of pediatric (PID) and adult infectious diseases (AID) providers, and a listserv of general pediatric practitioners in the St Louis, USA metropolitan area. RESULTS: Respondents identified the highest risk of SARS-CoV-2 transmission in spending time in a bar, eating at a restaurant, and attending an indoor sporting event. In the school setting, lower risk was identified in elementary and daycare students compared to high school or university-level students. Comparatively, the risk of transmission to students and teachers was lower than the identified high-risk social activities. Factors increasing risk perception in social activities included the absence of children in the respondent's household and female gender. For the school setting, AID providers perceived greater risk compared to PID providers or pediatric practitioners. CONCLUSIONS: Respondents identified high risk activities that were associated with a high density of participants in an indoor space where masks are removed for eating and drinking. Differences were apparent in the school setting where pediatric providers perceived lower risks when compared to adult providers.

Diagnostic delays in infectious diseases.

OBJECTIVES: Diagnostic delays are a major source of morbidity and mortality. Despite the adverse outcomes associated with diagnostic delays, few studies have examined the incidence and factors that influence diagnostic delays for different infectious diseases. The objective of this study was to understand the relative frequency of diagnostic delays for six infectious diseases commonly seen by infectious diseases (ID) consultants and to examine contributing factors for these delays. METHODS: A 25-item survey to examine diagnostic delays in six infectious diseases was sent to all infectious diseases physicians in the Emerging Infections Network (EIN) who provide care to adult patients. Diseases included (1) tuberculosis, (2) non-tuberculous mycobacterial infections, (3) syphilis, (4) epidural abscess, (5) infective endocarditis, and (6) endemic fungal infections (e.g., histoplasmosis, blastomycosis). RESULTS: A total of 533 of 1,323 (40%) EIN members responded to the survey. Respondents perceived the diagnosis not being considered initially and the appropriate test not being ordered as the two most important contributors to diagnostic delays. Unusual clinical presentations and not consulting ID physicians early enough were also reported as a contributing factor to delays. Responses recorded in open-text fields also indicated errors related to testing as a likely cause of delays; specifically, test-related errors included ordering the wrong laboratory test, laboratory delays (specialized labs not available at the facility), and lab processing delays. CONCLUSIONS: Diagnostic delays commonly occur for the infectious diseases we considered. The contributing factors we identified are potential targets for future interventions to decrease diagnostic delays.

Coronavirus disease 2019 (COVID-19) vaccination preparedness policies in US hospitals.

We surveyed infectious disease specialists about early coronavirus disease 2019 (COVID-19) vaccination preparedness. Almost all responding institutions rated their facility's preparedness plan as either excellent or adequate. Vaccine hesitancy and concern about adverse reactions were the most commonly anticipated barriers to COVID-19 vaccination. Only 60% believed that COVID-19 vaccination should be mandatory.

Clinical characteristics of COVID-19 in solid organ transplant recipients following COVID-19 vaccination: A multicenter case series.

BACKGROUND: Solid organ transplant recipients (SOTR) have diminished humoral immune responses to COVID-19 vaccination and higher rates of COVID-19 vaccine breakthrough infection than the general population. Little is known about COVID-19 disease severity in SOTR with COVID-19 vaccine breakthrough infections. METHODS: Between 4/7/21 and 6/21/21, we requested case reports via the Emerging Infections Network (EIN) listserv of SARS-CoV-2 infection following COVID-19 vaccination in SOTR. Online data collection included patient demographics, dates of COVID-19 vaccine administration, and clinical data related to COVID-19. We performed a descriptive analysis of patient factors and evaluated variables contributing to critical disease or need for hospitalization. RESULTS: Sixty-six cases of SARS-CoV-2 infection after vaccination in SOTR were collected. COVID-19 occurred after the second vaccine dose in 52 (78.8%) cases, of which 43 (82.7%) occurred ≥14 days post-vaccination. There were six deaths, three occurring in fully vaccinated individuals (7.0%, n = 3/43). There was no difference in the percentage of patients who recovered from COVID-19 (70.7% vs. 72.2%, p = .90) among fully and partially vaccinated individuals. We did not identify any differences in hospitalization (60.5% vs. 55.6%, p = .72) or critical disease (20.9% vs. 33.3%, p = .30) among those who were fully versus partially vaccinated. CONCLUSIONS: SOTR vaccinated against COVID-19 can still develop severe, and even critical, COVID-19 disease. Two doses of mRNA COVID-19 vaccine may be insufficient to protect against severe disease and mortality in SOTR. Future studies to define correlates of protection in SOTR are needed.

Testing Practices for Fungal Respiratory Infections and SARS-CoV-2 among Infectious Disease Specialists, United States.

In an online poll, 174 infectious disease physicians reported that testing frequencies for coccidioidomycosis, histoplasmosis, blastomycosis, and cryptococcosis were similar before and during the COVID-19 pandemic, indicating that these physicians remain alert for these fungal infections and were generally not concerned about the possibility of under-detection.

Variability in the Use of Novel Diagnostic Technology in Children With Suspected Encephalitis and in the Management of Emerging Encephalitides by Pediatric Infectious Disease Providers.

We surveyed pediatric infectious disease physicians through the Infectious Disease Society of America's Emerging Infections Network regarding the diagnosis and management of encephalitis. We identified practice variations, particularly with the use of new diagnostic modalities and management of autoimmune encephalitides. These findings may inform the creation of updated management guidelines.
