IDWeek 2018: Why We Still Don’t Wash Our Hands

At IDWeek 2018, the annual conference for the Infectious Diseases Society of America, I was struck by one simple truth.

We are still talking about washing our hands, or in our professional lingo, hand hygiene.

Hand hygiene is the simplest, most effective way to prevent infection. Most of us know this intuitively, without the science, as we grew up being reminded by our parents and teachers to wash our hands. It simply makes sense. Our hands are the most exposed part of our body and are in constant contact with our non-sterile environment (fecal veneer, anyone?). If someone does not wash their hands in the restroom, we are aghast. Don’t they realize that is a health risk?

This issue even resulted in an #IDWeek2018 Twitter post regarding the excellent hand hygiene in the restrooms.

Consider that, excellent hand hygiene noted by healthcare workers, as compared to what? Their home, hospital or clinic? Where else do they observe more hand washing?

We take those hands and feed ourselves, our loved ones. We provide care, and perform procedures and surgeries (with gloves as further protection, of course). But since 1847, when Semmelweis demonstrated the value of hand washing, we have struggled to have full compliance with hand hygiene in healthcare. In the face of the continual fight against sepsis, still we talk, study, and publish articles on the importance of hand washing.

The simplest thing. Wash your hands. Or now, use the hand sanitizer. Before and after patient care. Before eating, after using the restroom. It takes 15 seconds or less, depending on the method. It is so easy. Session discussions included ideas on how to monitor hand washing – direct observations on the unit? App use for recording hand hygiene opportunities? Technology on badges or door frames? Silent monitoring on sinks? Why on Earth would we still need sessions on achieving adherence with hand hygiene in 2018? Why do we not all simply do what we know is best for the health of ourselves and our patients?

This, my friends, is where sociology, more specifically, sociobehavioral science comes into play.

There may be ample science showing the benefits of handwashing. There are pre-created campaigns for handwashing (5 Moments of Hand Hygiene from WHO), and even specific marketing focused on hand hygiene. Not to mention the seemingly endless amounts of hand sanitizer and sinks with soap that can be found in every hospital.

It turns out that knowing the science and being reminded is simply not enough. A four-hour workshop led by Dr. Julia Syzmczak (University of Pennsylvania) at IDWeek entitled “Changing Hearts and Minds: A Sociobehavioral Approach to Antimicrobial Stewardship and Infection Prevention” focused on the fact that science and education do not necessarily equate to behavioral changes in humans (improved hand hygiene). How we as humans behave in a hospital is subject to the same sociologic pressures as the rest of the world. We are not robots, we are humans. We are subject to the impact of perceptions and perceived culture. And if I learned anything, I learned that culture will beat science EVERY DAY OF THE WEEK when it comes to human behavior.

So, what does this mean for us? Do we stop trying? Do we stop innovating?

No, of course not. But, we need to stop forgetting that the successful implementation of science and best practices carries a wild card with it – humanity.

Medical care is increasingly complex, fast-paced and full of “priorities” for providing state of the art care. The reality is, not everything can be a priority. In a realm of competing priorities, how does a single provider pick which priority is actually most important? Will preventing infection via handwashing always fall at the top of the priority list? Should it?

Where do we go from here? The answer, I believe, is as infectious diseases physicians, healthcare epidemiologists, infection preventionists, healthcare providers and patients, we must give human behavior and sociology, an equitable seat at the table with science.

We need to address the competing priorities, study and understand the behaviors we want to change (not always washing your hands) and why that behavior exists. Then focus our interventions on the behavior itself. Science and education are critical to this role; but can no longer be touted as the holy grail of implementation. We need to consider human nature, the social constructs of our institutions, our organizational ‘culture.’

It is crucial that we embrace the sociologic components of healthcare as we strive to continually provide the best possible care for our patients.

Why? Because in the end, we are all patients.

And as your patient, I want you to wash your hands.

Pharm to Exam Table: Doravirine DRIVES the way to more ART options

The Department of Health and Human Services HIV guidelines panel currently recommends antiretroviral therapy (ART) consisting of two nucleoside reverse transcriptase inhibitors plus an integrase inhibitor for most treatment naïve HIV infected individuals1.  Prior to the advent of integrase inhibitors, the utilization of non-nucleoside reverse transcriptase inhibitor (NNRTI) based regimens had been common.   Both efavirenz and rilpivirine had been commonly used although both NNRTI’s present some challenges.  Efavirenz related neuropsychiatric adverse effects and drug metabolism enzyme induction properties present challenges for its use.  Rilpivirine has been shown to be less efficacious in naïve patients with baseline viral loads greater than 100,000 copies per milliliter or CD4 counts less than 200/cmm.  In addition, patients requiring a proton pump inhibitor cannot use rilpivirine due to its need for an acidic environment to be absorbed.  An NNRTI without similar restrictions may be beneficial.

Doravirine (DOR) is a novel NNRTI that provides a similar efficacy for the treatment of HIV infection with activity against HIV variants that are resistant to efavirenz (EFV) and rilpivirine (RPV).  Doravirine offers a better safety profile without neuropsychiatric adverse effects, minimal drug-drug interactions and is unaffected by food intake and need for an acidic absorption environment.  In August, 2018, doravirine was approved by the FDA for use and will be available solely (Pifeltro™) or as a single tablet regimen (Delstrigo™) in combination with lamivudine (3TC) and tenofovir disoproxil fumurate (TDF).

Two phase III trials, DRIVE-AHEAD and DRIVE-FORWARD, provided the basis for FDA approval.  The summary of these trials follows.

DRIVE-AHEAD2: A randomized, double-blind, phase III trial compared doravirine to another NNRTI, efavirenz. Adults with HIV-1 infection naïve to ART, HIV RNA >1,000 copies/ml, and CD4 >100/mm3 were randomized to receive DOR 100mg with 3TC 300mg/TDF 300mg or EFV 600mg with TDF 300mg/emtricitabine (FTC) 200mg. The primary endpoint of the study measured virologic response with the proportion of patients achieving HIV RNA <40 copies/ml at week 48. Comparisons between each arm were similar, 77% in DOR arm vs. 78% in EFV arm, demonstrating non-inferiority. Clinical adverse events deemed drug-related were reported in 31% of patients in DOR arm and 56% in EFV arm.  Dizziness (6.5% DOR vs. 25% EFV) and abnormal dreams (5.6% DOR vs. 14.8% EFV) had the largest variation between the two groups. Only one emergent NNRTI mutation arose to the DOR group, K101K/E mutation, which causes intermediate resistance to RPV and low-level resistance to EFV.

DRIVE-FORWARD3: A randomized, controlled, double-blind, phase III, non-inferiority trial compared doravirine to ritonavir-boosted darunavir, a protease inhibitor. Adults with HIV-1 infection naïve to ART, with plasma HIV RNA >1,000 copies/ml were screened and randomized to receive DOR 100mg or DRV 800mg/RTV 100mg (DRV/r), in combination with either TDF/FTC or ABC/3TC based on investigator choice. The proportion of patients that achieved plasma HIV-1 RNA <50 copies/ml at week 48 defined the primary endpoint of this trial. Doravirine showed non-inferiority to ritonavir boosted darunavir, with 84% in DOR arm vs. 80% in DRV/r arm achieving success with HIV RNA <50c/ml at week 48. Clinical adverse events due to drug therapy were reported in 31% in DOR and 32% in DRV/r group, with diarrhea comprising 5% of DOR patients vs. 13% of DRV/r patients. Lab abnormalities were similar between the two regimens, except LDL-cholesterol increases in <1% of DOR patients vs. 9% of DRV/r patients. Resistance testing was performed in 15 protocol-defined virologic failure (PDVF) patients, and within this group no emergent mutations to DOR were found. One case of resistance was found in a patient that discontinued treatment because of non-compliance at week 24, thus was not included in the PDVF category, encompassing resistance to DOR (V106I, H221Y, F227C) and FTC (M184V).

In summary, doravirine paired with 3TC/TDF demonstrates similar efficacy to regimens anchored by efavirenz or ritonavir boosted darunavir at week 48 in HIV infected treatment naïve patients.  Doravirine demonstrated an acceptable tolerability and safety profile with very little treatment emergent ART resistance mutations.  Studies investigating a switch to DOR/3TC/TDF in virologically suppressed experienced patients (DRIVE-SHIFT) and in ART naïve patients with NNRTI transmitted resistance are currently ongoing.  However, comparisons of doravirine based regimens versus any of the currently recommended INI based regimens is unknown.

Update for HIV Care Providers and Educators Revived and Reinvigorated!

Content written by Nikki Regan, APRN

After a several year hiatus, the UNMC HIV Update conference was back and better than ever.  The conference planning committee at the UNMC/Nebraska Medicine Specialty Care Clinic started organizing this event over a year ago.  “The interest was definitely there,” said Ann Fitzgerald, APRN at the clinic and AIDS Education and Training Program Director for Nebraska. “In the past we have had about 80 attendees. This year’s conference brought in over 100 participants, and according to our live polling, 40% of them were first-time attendees.”

The attendees were from diverse backgrounds, including social workers, nurses, advance practice providers, physicians, pharmacists, dentists and public health workers, with some people travelling over 50-100 miles to attend.

The HIV Update conference was jam-packed with hot topics, focused on a multidisciplinary approach to care.

  • Dr. Sara Bares kicked the morning off with a review of new and upcoming approaches for the management of HIV. She shared information about the updated treatment guidelines, as well as new FDA approvals and other treatment options coming down the pipeline, such as long-acting injectable ARV therapy.
  • Dr. Mark Malliard shared the joy and new-found simplicity of treating Hepatitis C–“You will cure their Hepatitis C, and your patients will love you.”
  • Dr. Jasmine Marcelin gave a moving presentation on the history and persistence of disparities in healthcare for people living with HIV, especially people of color. She urged the audience to move the focus from equality to equity, and ultimately—social justice.
  • Josh Havens, PharmD, discussed Pre-Exposure Prophylaxis (PrEP) for HIV negative patients and encouraged providers who aren’t yet providing PrEP to consider doing so. Unfortunately, there are few providers in the area who are prescribing PrEP at this time.
  • Dr. Jean Amoura deciphered terminology and care considerations related to transgender care.
  • Dr. Susan Swindells, Kim Scarsi, PharmD, and Precious Davis, MSN, opened up discussion of several case-based scenarios to demonstrate how the inter-professional team can work together to meet the needs of complex patients.
  • Dr. Mario Sanchez and Dr. Alex Dworak, from One World Community Health Center, teamed up to highlight the importance of addressing mental health and substance abuse disorders. Their advice for uncovering these comorbidities: “Ask. Then be prepared for the answer.”
  • Daniel Cobos, RN, MPH and Nikki Regan, APRN, wrapped up the day with an entertaining debate regarding condoms. Cobos argued that in the era of U=U and PrEP, condoms are outdated. Regan noted the increase prevalence of other STIs, as well as the underlying complexity of U=U, and suggested we “keep condoms in the conversation”.

Community partners, including Douglas County Health Department and Charles Drew Health Center, were also on hand to promote their services and interact with providers.

The Planning committee would like to thank all of their sponsors and partners for the event, including the Midwest AIDS Training & Education Center, and the Nebraska Ryan White Part B program.  The committee would also like to thank Deanna Hansen, Deb Justesen and Sara Weber for their hard work in keeping the conference running smoothly throughout the day. You can find more quotes, photos, and audience reactions to the day on Twitter: #UNMCHIV2018, and be sure to follow @UNMC_ID to be the first to hear about future conferences!

An Empiric Nudge in the Right Direction

The following review was originally posted by Dr. Marcelin to the September 2018 SHEA Journal Club and featured on Medscape’s SHEA Expert Commentary earlier this month. 

Use of empiric antimicrobial treatment in acute care settings is often the result of the “diagnosis momentum” heuristic, wherein the antibiotics started in one location for “sepsis” are continued for several additional days after transfer to a second location. Vancomycin remains one of the most commonly prescribed inpatient antibiotics, despite a decline in prevalence of invasive MRSA infections. The authors of the first article “Rate of positive cultures necessitating definitive treatment in patients receiving empiric vancomycin therapy” compared the rate of actual positive culture requiring vancomycin to the rate of vancomycin use in a single-center retrospective observational study. The majority of these infections were SSTIs, bacteremia and pneumonia.

Concern for MRSA is likely the driver of overuse of vancomycin, yet this organism was confirmed in only 8.4% of the positive cultures. Over the three-month period studied, only 11% of 1662 patients on vancomycin had a positive culture necessitating vancomycin use as definitive therapy.  This means that up to 90% of patients on empiric vancomycin can likely be safely de-escalated, especially after 48 hrs. of negative cultures.  However, convincing prescribers to discontinue presents a separate challenge for Antimicrobial Stewardship Programs (ASP).

In the second article, “Microbiology Comment Nudge Improves Pneumonia Prescribing”, the authors capitalized on the fact that perhaps most decisions to start empiric vancomycin/piperacillin-tazobactam in setting of pneumonia occur in the context of concern for unidentified MRSA or Pseudomonas aeruginosa. Even with negative cultures, are prescribers continuing these antibiotics because of a fear that these bacteria are lurking in the cultures, but missed by the microbiology lab? In active stewardship education, we can tell people “the likelihood that MRSA or pseudomonas is going to be present in a person without specific risk factors is low”. In a complex patient care scenario however, prescribers can talk themselves into the possibility of these bacteria being present even when it highly unlikely. What if the micro lab could say unequivocally that these organisms were absent; would that change practice?

In this quasi-experimental study conducted within a 4-hospital system in Detroit, the microbiology lab cultured respiratory specimens of individuals being treated for pneumonia. The lab made a simple modification to their reporting system for normal “commensal respiratory flora” (which included growth of Neisseria, Corynebacterium and Streptococcus, with no dominant growth of any single organism). The lab added the statement: “No S. aureus/MRSA [methicillin-resistant Staphylococcus aureus] or P.[Pseudomonas] aeruginosa” to the report, and the ASP provided a brief education to prescribers.  

After this behavioral nudge was implemented, prescribers were 34% (p<0.01) and 5.5-fold more likely to de-escalate antibiotics than when the report only stated “commensal respiratory flora”. Additionally, with fewer vancomycin/piperacillin-tazobactam combination days of therapy (DOT), they noted a 17% reduction in acute kidney injury (p<0.03) even after adjusting for severity of illness with APACHE II or Charlson comorbidity index scores.  The DOT of MRSA and antipseudomonal therapy was reduced from 7 to 5 days (P<0.01). The authors do not state how long their lab took to finalize cultures, but assuming at least a preliminary result of the “commensal respiratory flora” comment nudge in 48 hrs. even the intervention arm had room for earlier de-escalation, with a median empiric DOT of 5 days. Multidrug-resistant organisms (MDROs) were not generally prevalent in either group, however there was a significant difference in development of subsequent MDROs after the culture result nudge (8% vs 1%, p=0.035). Despite these significant stewardship outcomes, however, no effect on mortality, development of Clostridium difficile infection, or change in length of ICU/hospital stay was observed.

Behavioral nudges use positive reinforcement and indirect messaging to influence decision-making, and exist in many areas of our clinical environment already. Many microbiology labs already include resistance markers in the rapid diagnostic test results, which serve to passively guide prescribers to appropriate antibiotic choices. As ASPs aim to collaborate with prescribers to change behaviors, these behavioral nudges can be a useful low-effort/high-yield tool to further assist with antibiotic de-escalation, even in critically ill patients.

Dancing with the Doctors – An Event for Child Life 

This is a theme the pediatric patients are used to: bright lights and surrounded by doctors while their families are anxiously waiting nearby hoping for the best.  This time, the patients and doctors will meet outside of the Medical Center and their hospital gowns will be replaced with ballroom gowns.

Under the coaching of Vintage Ballroom instructor, Rebekah Pasqualetto, three pediatric patients are teaming up with the doctors’ who saved them to put on the biggest performance of their young lives. The dancing isn’t easy. Between school, doctor appointments, and daily lives the girls dedicated two months to learning three styles of dance: Rumba, Merengue, and Country Swing. Each song matches the personality of each child. 11-year old Daisy likes to dance with her friends to the latest pop hits. 12-year old Maura has dance training from previous years of ballet. Even with surgery restrictions, Maura is adamant about performing a trick on the dance floor. 12-year old Raeleigh loves fashion, she is very considerate of others. Raeleigh will be joined on the dance floor by her younger sister Addisyn who suffers from watching Raeleigh undergo treatment.

The girls will not be partnered up with strangers. They will be dancing with their doctors and they love it. Unfortunately, years of medical experience do not transfer to dancing. The doctors – Alan Langnas, David Mercer, James Ford, and Sachit Patel – also need to train at Vintage Ballroom to prepare for the show.

The show is quite special. Dancers from across the country will file into the Hilton Double Tree Banquet hall for the Nebraska Dance Festival on October 20, 2018. The day-long event will be filled with hundreds of competitors trying to out-dance one another. You can find more details about the event at https://www.nebraskadancefestival.com/

Dr. Diana Florescu is coordinating the fundraiser with Child Life, Vintage Ballroom, and Nebraska Dance Festival. The organizers of Nebraska Dance Festival – Amanda & Ilya Reyzin and Igor Litvinov – are supporting Child Life Services from University of Nebraska Medical Center! Through their donation, they will share the gift of reading and spread some fun to pediatric patients at Nebraska Medicine. Hospitalization can be a scary and isolating experience for children and teens. Many of the kids are hospitalized for long periods of time – months or even years – due to the severity of their illnesses. Books and games will allow kids to experience normalcy, socialization, and continued growth and development while hospitalized.

Please come to encourage these amazing kids and watch our doctors perform! You can also support these amazing kids by donating at www.nufoundation.org to Nebraska Medicine Child Life Impact Fund (#01145270).

Intensive Infection Control experience for UNMC ID Fellows

The Nebraska Medicine Infection Control and Epidemiology Department (IC&E) is well recognized for excellence. The department is staffed by 5 full-time Infection Preventionists (IP), a data analyst, and a staff assistant; Terry Michaels, manages the department. Dr. Rupp serves as the Medical Director and is assisted by Drs. Ashraf, Cawcutt, Marcelin, and VanSchooneveld as Associate Directors.

During the first 2 years of ID Fellowship, UMMC ID fellows have terrific opportunities to learn about infection prevention and the hospital infection control program. Each fellow has a month-long elective in infection control – during that month of intense study, they learn the nuts and bolts of hospital infection control. Working alongside experienced IPs and medical directors, ID fellows have hands on observation of infection surveillance, healthcare associated infection prevention efforts, and outbreak investigation.

During the month rotation a small special project is also conducted and a specialized curriculum/lecture series is conducted. ID fellows are exposed to the infection control literature during a monthly infection control journal club in which they take turns critiquing recent publications along with IPs and faculty. The infection control experience is capped off by attendance of the SHEA/CDC basic course in Hospital Epidemiology. For the ID fellow interested in infection control as a career, opportunity for a third year of Fellowship directed toward specialized training in infection control and hospital epidemiology is encouraged.

Additional opportunities for experience and research in infection control is afforded through the CDC/Nebraska HHS-funded Infection Control Assessment and Promotion Program (ICAP) that is charged with improving infection control practices in health care settings (long-term care, critical access hospitals, acute care, dialysis units, ambulatory surgical centers, etc.) across the state of Nebraska. Learn more about the Nebraska ICAP directed by Dr. Salman Ashraf at https://icap.nebraskamed.com/

Allergy Emancipation

The following was originally posted to the Controversies in Hospital Infection Prevention Blog on 9/24/18 by Dr. Marcelin.

September 28, 2018 marks 90 years since Sir Alexander Fleming discovered penicillin as an effective antimicrobial which would soon save millions of lives. He warned soon afterwards that unless we used penicillin judiciously, we would see antibiotic resistance, and he was right. With decades of inappropriate antibiotic prescribing, we have dug ourselves a deep hole of antimicrobial resistance, and inaccurate penicillin allergies is but one shovel used to put us in this mess. How? Simple If/And/Then construct: IF unverified penicillin allergies lead to unnecessary/inappropriate use of broad-spectrum antibiotics which contributes to antimicrobial resistance, AND antimicrobial resistance is a public health problem, THEN unverified penicillin allergies are a public health problem.

In a single day on hospital service the Infectious Diseases consult team encountered a few patients with beta lactam allergies: one had developed significant angioedema in the last year with amoxicillin; another had developed a questionable rash on nafcillin therapy; a third recalled his mother telling him that he turned green after receiving oral penicillin as a child. Our approach: in the first case we avoided penicillin; in the second, we recommended a cephalosporin graded challenge which the patient tolerated; in the third, after detailed history we gave the patient full dose amoxicillin-clavulanate, he tolerated it well and he was able to discharge without IV antibiotics. These are fantastic cases for teaching purposes, but additionally, how exhilarating it is to liberate a patient from an irrelevant penicillin “allergy” and give them appropriate treatment upfront!

Penicillin allergies are frequently documented drug allergies in the hospital setting, with 10% of Americans reporting a penicillin allergy.  Some penicillin allergies are real. However, most penicillin allergies are either inaccurate or inconsequential, with only 1% of Americans actually demonstrating true allergy upon testing. Furthermore, most patients with true penicillin allergies lose hypersensitivity over time, and by 10 years after the event, 80% of patients are no longer penicillin allergic. Can you imagine if all potential food allergies were treated the same as penicillin allergies? People wouldn’t eat at all! Most people, if they have what they think might be a reaction to a food they like, might either try the food again or get tested to know for certain they cannot eat that food. But 50 years ago, if they had a rash that coincided with penicillin administration, it would never occur to them to try it again.

Once a penicillin allergy is listed in a patient’s record, they are more likely to receive inappropriate broad-spectrum antibiotics – a practice that can be both costly and have worse clinical outcomes.  Patients with methicillin-susceptible Staphylococcus aureus bacteremia treated with vancomycin instead of a beta-lactam have higher mortality rates than those receiving appropriate beta-lactam therapy. Patients undergoing surgery who receive alternative antibiotics for preoperative infection prophylaxis (due to reported penicillin allergies) have a 50% higher risk of developing a surgical site infection than those who appropriately receive beta lactam prophylaxis.

The Infectious Disease Society of America (IDSA) and Society of Healthcare Epidemiology of America (SHEA) recommend that patients with reported beta lactam allergy should undergo beta lactam allergy skin testing. Allergy verification and penicillin allergy skin-testing are becoming more recognized components of antimicrobial stewardship and de-labelling allergies can have significantly improved patient outcomes.  Following a simple algorithm can help to easily identify patients suitable for skin testing and could avoid almost 3 weeks hospitalization and 1000 days of second-line antibiotics. However in some situations or in low-resource settings, it may not be practical to perform skin testing on everyone who reports a penicillin allergy. In a previous blog post about beta-lactam skin testing I mused about whether better allergy histories are more bang for the buck, since a structured allergy history can potentially decrease inappropriate 2nd line antibiotic use by 26%.

There’s an age-old joke that if a team wants a detailed history on a patient, just consult ID. If our attention to detail is already expected, shouldn’t we feel empowered to take that allergy history and de-label the penicillin allergy?  Inpatient allergy consultations are difficult to coordinate when those divisions may be understaffed and allergists are busy with outpatient practices.  So how can we capitalize on their expertise when they can’t see the patient in the hospital? Simple: partner with them to create guidance for practice, utilize ordersets for allergy de-labelling and facilitate outpatient allergy evaluations after discharge.

In honor of Sir Alexander Fleming and National Penicillin Allergy Day, let us pledge to emancipate our patients from the fake allergies. Go on, get that detailed history! Get some penicillin skin testing! Do that graded challenge! Give that first line beta-lactam antibiotic! But for goodness’ sake when you do, please DELETE the allergy from the health record so that the ordeal does not have to be repeated!

UNMC ID Division Accolades!

Our Faculty at University of Nebraska Medical Center Division of Infectious Diseases have worked hard to maintain a strong academic presence at UNMC. We are a growing division, filled with faculty at all stages of their careers, and their collective academic prowess has our division leading the pack.  We are proud of our faculty and would like to share some of their accomplishments with our followers.

Dr. Angela Hewlett has been elected to the Executive Board of the Musculoskeletal Infection Society and will serve as MSIS President in 2020. She was recently an invited delegate at the International Consensus Meeting on Periprosthetic Joint Infection in Philadelphia, where experts in orthopedic infections from around the world (over 80 countries were represented) came together to develop a document based on the available scientific evidence and consensus when evidence is lacking, that can be used to improve the care of patients with musculoskeletal infections. Dr. Hewlett will be an invited speaker at #IDWeek2018 at the Meet the Professor Session on outbreak preparedness. She also published  the book,  Bioemergency Planning: A Guide for Healthcare Facilities.

Dr. Jasmine Marcelin was awarded the SHEA Race Against Resistance Scholarship, funding provided for a new Antimicrobial Stewardship clincian to learn more about the field. Dr. Marcelin partnered with Physicians Weekly to co-moderate two twitter chats on Minorities in medicine, and was recently featured on the cover of the July issue of Helio Infectious Diseases News in an article discussing Women in Infectious Diseases.

Dr. Susan Swindells was awarded the Department of Medicine Faculty Clinical and Educational Mentoring Award.

Dr. Trevor Van Schooneveld was recently named UNMC College of Medicine Resident Program Director of the Month in September (ID Fellowship Program Director)
