M4 Students in our HIV Enhanced Education Track present Capstone Projects…and Today is MATCH DAY!

The UNMC College of Medicine offers a unique Enhanced Medical Education Track (EMET) program which provides an opportunity for medical students to delve into particular disciplines of interest in the field of medicine throughout their four year degree program. Track students attend seminars, preceptorships and complete a research project culminating in a poster or conference presentation.

Yesterday, on the eve of their Match Day, our two M4 Students, Rebecca Osborn and Daniel Cloonan (under the mentorship of Dr. Sara Bares) presented their Capstone Projects at UNMC College of Medicine.

Today, after years of hard work, months of interviews, weeks of decision and the most anxiety-filled week of their lives, they found out where they will be spending the next few years of their lives as newly minted doctors.

Rebecca’s project focused on a collaborative care program to help with medication adherence in patients living with HIV.  This collaborative worked with a local community pharmacy to create a program of direct engagement between pharmacists and patients in order to improve adherence. She will be submitting her work for presentation at a national conference and for publication. Rebecca will be continuing her medical training with Internal Medicine Residency at Yale. We wish her all the best and hope to see her again in the future for ID fellowship!

Daniel’s project looked at the gender affirming hormone therapy taken by transgender patients and possible interactions with Pre-exposure prophylaxis (PrEP), which is recommended to help prevent HIV infection in persons at high risk for acquiring the disease. Because of a fear of drug-drug interactions, many transgender individuals may avoid PrEP when they are at high risk, fearing an interruption in their hormone therapy. Daniel’s study is part of a larger study being led by Kim Scarsi, PharmD (HIV Clinical Pharmacist at the Specialty Care Center and Associate Professor in the College of Pharmacy) and Lauren Cirinccione, PharmD (Pharmacy Practice Fellow). The project, collaborating with the UNMC College of Pharmacy, hopes to answer this question and by doing so, remove some barriers to PrEP engagement when needed. Daniel will be continuing his medical training with a General Surgery Residency at Beth Israel Deaconess Medical Center. We wish him all the best in the future!

Each year, our UNMC HIV clinic takes two medical students into the EMET track, and we look forward to working with them over the course of their undergraduate medical training to immerse them in HIV care and Infectious Diseases. We will soon be announcing our new M1 EMET students, who will start working with us over the coming summer.

Congratulations again to Becky and Daniel, we are proud of you! And congratulations to all M4s out there who found out where they matched today!

What Patient Safety Means to Us – Part 2

In endeavoring to give you a real flavor of how important patient safety is to all of us, we have more comments today from our team. Patient safety is important to all of us and we wish we could highlight the all of important work everyone in our Division is doing to provide the best possible care while still preventing harm.

 

Adrienne Sy, RN, BSN; Quality Lead for CLABSI & CAUTI reduction starts us off today:

Patient safety means protecting someone’s loved one from harm.  My grandmother passed away after a fall two weeks before I took the NCLEX, and my mother-in-law passed away after a bloodstream infection three months after I got to marry her eldest son.

Two things that I am very excited to help run/coordinate are the CAUTI and CLABSI Roundups.  It gives me a chance to work with the nursing units, and I believe that these have been very helpful in identifying what is done well and what our areas of opportunity are.

 

Michelle Schwedhelm, RN adds a great global view of safety at Nebraska Medicine/UNMC:

Patient Safety is creating a safe zone and processes for patients seeking care at Nebraska Medicine. 

One project is doing Fire and Severe Weather Drills with our staff to assure they know how to evacuate and how to mitigate danger for our patients.  Another is our new Daily Shout Out meeting where we identify safety issues for patients and staff and encourage prompt resolution.  Visibility is at the highest levels of the organization.

 

Dr. Kelly Cawcutt on preventing harm in the ICU:

Dr. Kelly Cawcutt, Associate Director of Infection Control and Epidemiology

Patient safety is about always providing the best patient-centered care while preventing harm, for all patients. I work in the ICU also, and there we are providing care to the sickest patients in the hospital and often have to use invasive procedures and devices for life support measures. Providing excellent clinical care is one component of patient safety, but through working in Infection Control, I can also focus on preventing harm are a larger scale from how we prevent the spread of infections in the hospital to which types of devices we use in the ICU. 

Some examples of projects I have worked on are developing a vascular access algorithm to ensure we use the right device at the right time for our patients – whether that is a peripheral IV, midline, central venous catheter or another type of device. I also am working on how to address and prevent ventilator-associated events, including pneumonia, for our patients who require mechanical ventilation in the ICU. These projects reduce harm, prevent adverse events and in the end, I believe this work helps save lives. 

 

To me, patient safety is about imagining yourself as each patient or family member being cared for in the hospital, and asking “is the care I’m delivering what I would want for myself or my family?”, and if the answer to that is “no”, personally seeking ways to improve that care for our patients. 

Dr. Jasmine Riviere Marcelin is the Associate Medical Director, Nebraska Medicine Antimicrobial Stewardship Program

Much of my work in Antimicrobial Stewardship is focused on reduction of antibiotic use, primarily with a patient safety mission. Antibiotics are the only drugs where an individual prescriber’s use can affect patients s/he never even cared for. For example, when patients are prescribed antibiotics for viral illnesses which do not require them, this may lead to development of bacteria resistant to antibiotics. When a patient in that community then develops a serious bacterial infection with this resistant organism, they may face grave complications from the actual bacteria or from use of alternative antibiotics with serious adverse effects or toxicities. Collaborating with the Nebraska Antimicrobial Stewardship Assessment and Promotion Program (ASAP) and Nebraska Health Network (NHN), I created several educational materials for outpatient prescribers on appropriate use of antibiotics in upper respiratory illnesses.

Additionally, skin/soft tissue infections are another area where antibiotics are overused, and I personally have seen patients develop kidney failure from combination treatment with vancomycin and piperacillin-tazobactam for cellulitis when only cefazolin was indicated. I am currently working on updating our institutional skin/soft tissue infection guidance document which will help antibiotic prescribers make the right treatment choices for specific skin/soft tissue infections. These are just two of the many projects our Antimicrobial Stewardship Team are working on to decrease antibiotic overuse and misuse, keeping patients safe by reducing adverse effects, drug toxicities and antibiotic resistance. 


 

Antimicrobial Stewardship Program Takes Patient Safety Personally

At Nebraska Medicine, our Antimicrobial Stewardship Program’s (ASP) clinical mission is to optimize the utilization of antimicrobial agents, thereby improving patient outcomes (by reducing the risk of adverse events and Clostridium difficile infection) and limiting the spread of antimicrobial resistance.   These Antimicrobial Stewardship activities have been mandated by the Joint Commission and our program has been expanding its reach to include our satellite hospitals and our outpatient clinics to achieve this mission. Since a large majority of inappropriate antibiotic use occurs outside of the hospital, our outpatient initiatives are currently focused on education of clinic providers and patients on not using antibiotics for conditions that do not require them.

On the inpatient side, our stewardship activities have many impacts on patient safety.  First, many studies have demonstrated the benefit of early Infectious Disease consultation for patients with Staphylococcus aureus bloodstream infection (SAB). When ID doctors are involved, patients are less likely to die or suffer complications, respond faster to therapy and will have fewer adverse effects.  At Nebraska Medicine, we review approximately 150 SAB cases per year to prompt ID consultation. In addition, the discussion between the ASP reviewer and the primary team ensures the appropriate antibiotic is started immediately, even in advance of the ID consultation.

Last year, our ASP program documented over 2500 reviews of patients for appropriate antibiotic use, with 381 interventions to reduce antibiotic use by either discontinuing or de-escalating therapy, with a 90% acceptance rate of interventions. Not only did we assist with narrowing antibiotic use, 97 patients with untreated or resistant infections were identified and subsequently initiated on therapy as a result of ASP review, and nearly 200 ID consult requests were implemented in highly complex cases.

Furthermore, our ASP interventions have also resulted in reductions of vancomycin and piperacillin/tazobactam combination therapy when unnecessary. The combination of these two antibiotics has been shown to increase risk of kidney failure (which leads to worse clinical outcomes for patients), and the simple act of switching to alternative antibiotics to avoid this risk has tangible patient safety benefits.

In 2016, new initiatives were introduced to improve timing and redosing of antibiotic prophylaxis for surgery, in an effort to reduce the risk for surgical site infections (SSI). Coupled with the new SSI prophylaxis guidance, the program developed guidance on how to manage patients with beta-lactam allergies.  This is important for patient safety because many patients receive 2nd or 3rd line antibiotics inappropriately in the context of remote penicillin allergies. Sometimes, like in the case of surgical prophylaxis, the data is clear that use of antibiotics other than cefazolin can lead to increased SSI risk. Providing evidence-based guidance in collaboration with our allergists empowers physicians to provide best care for their patients without perceived harm of allergic reactions.

Antimicrobial stewardship is the balance between treating patients effectively and keeping them safe from harm.

Here at Nebraska Medicine, we take that balance personally; practicing Serious Medicine, delivering Extraordinary Care.


 

What Patient Safety Means To Us – Part 1

As mentioned on Monday, patient safety is a primary focus of our work, particularly in Infection Control and Epidemiology. To really highlight the commitment to this initiative, we wanted to share a series on what patient safety means to us and a few examples of how we have implemented that into our work.

 

Per Dr. Mark Rupp,  Division Chief and Medical Director of Infection Control & Epidemiology:

Patient safety, is the very reasonable expectation from our patients, that although in healthcare we do things that are inherently dangerous, we minimize the risk of harm as much as is possible.  Quite simply, we eliminate preventable harm.

In the Infection Control and Epidemiology Department our whole effort is dedicated toward minimizing the occurrence of healthcare associated infections (HAIs). 

In recent years at Nebraska Medicine we have taken aggressive measures to decrease central line associated bloodstream infections (CLABSI) and catheter-associated urinary tract infections (CAUTI).  We emphasize horizontal interventions which are measures that impact all patients or broad groups of patients – examples of horizontal interventions are hand hygiene, chlorhexidine bathing, and environmental cleaning and disinfection.  At the present time we are in the middle of a campaign to decrease infection due to Clostridium difficile and launching programs to further limit infections following surgery (surgical site infections).  Much of the work we do is behind the scenes and includes making sure the air is safe, the water is free of pathogens, and systems to provide clean and sterilized instruments and devices are working properly.” 

 

Dr. Angela Hewlett, Medical Director of Clinical Operations for the Biocontainment Unit,  Associate Medical Director of Infection Control & Epidemiology and Director of Infectious Diseases Outpatient Clinic said:

To me, ‘patient safety’ is the practice of doing everything we can to prevent harm from coming to our patients.  Patient safety protocols should be based on the best available scientific evidence and always be accompanied by education (for healthcare workers as well as patients).

 Examples:

  1. After it was noted that patients with fractures were placed on a variety of antibiotic regimens in an effort to prevent infections, I worked on a collaborative project with the Department of Orthopaedic Surgery to standardize antibiotic recommendations for patients with fractures.  We created an Epic order set, and conducted educational sessions with multiple physician groups, including the Emergency Department, Trauma Surgery and Orthopedics.  This evidence-based protocol will help with patient safety by ensuring that patients are receiving appropriate antibiotics and dosing for an appropriate amount of time. 
  2.  Chlorhexidine (CHG) bathing is a modality that has been shown to decrease healthcare-associated infections, and is a standard practice for all inpatients at UNMC.  Dr. Andrea Green and I created a survey of nursing staff to determine what barriers exist in regards to CHG bathing of patients.   We used the information generated from the survey to create education on the benefits of CHG bathing in an effort to increase compliance with this practice. 

 

Kim Hayes, RN and Infection Preventionist added her perspective with:

What does patient safety mean to me?  First and foremost, we must not harm our patients during the course of their treatment, either in our cares or with our devices.  We must be mindful that our patients were not always as we see them and their families have the expectation that we will keep them safe and not let harm come to them while they stay with us.

Two projects that I have been involved with were the CAUTI reduction team during which every nurse/tech in the facility was instructed in catheter insertion and appropriate catheter cares, supply lines were standardized and we updated our devices(sterile piston irrigation set).  The second was moving from the outdated split septum IV infusion sets and connectors to meet the industry standard with the needleless sets and connectors.  This was an enterprise wide change that touched every department and made IV treatment safer.  Alligator clips no longer popped off and infused medications into the bed linens, needles were no longer used in the system, so nurses are safer today as a result.

Patient Safety Awareness Week

“4 in 10 Americans say they have experienced a medical error in their own care or in the care of a loved one.”

Preventable Harm is critical to reduce in healthcare. It is a major cause of death, disability and costs, therefore the Institute for Healthcare Improvement created an initiative of Patient Safety Awareness Week from March 11 to the 17th. The mission is to raise awareness among providers and patients alike, to recognize the paramount importance of patient safety and that no matter what, WE ARE ALL PATIENTS. We all want medical care that is both excellent and safe.

How can you get involved with the events this week?

Take the pledge to help reduce harm.

Join the webinar at 12pm Central time for Engaging Patients and Providers: Speaking Up for a Culture of Safety

Join the Twitter chat. #PSAW18 Friday March 18th from 11AM -12PM Central Time on  Building a Culture of safety.

Check out resources for your institution and other events here: http://www.unitedforpatientsafety.org/

Here in the realm of Infectious Diseases, much of our work surrounds efforts that directly impact, and improve, patient safety. From antibiotic stewardship aid in improving our drug choices while minimizing adverse events to choosing the right types of IV catheters to even what may seem mundane, like making sure hand washing is easy-to-do and DONE! Throughout this week, we will be posting thoughts on what patient safety means to us and projects we have worked on that focus on patient safety.  This will included a broader array of the invaluable team members helping us all work toward safer healthcare everyday.


 

Match Day – Congratulations and Best Wishes!

Today is the day in which “the MATCH” happens for our 2018 students. This morning, at 11 AM they will find out if they matched into a residency program and this Friday, March 16, they will find out where they matched. Match Day is a day full of anxiety, excitement and some trepidation as you find out if you need to move, what city and state you may be relocating to before entering years of medical training as a resident.

The Match is meant to remove pressure and bias from both students and institutions during the process of choosing a residency program, but it is laced with the unknown and lack of control of where you go, and what you do next. It is a unique right of passage for physicians as they launch into the years of training after earning their MD.

Congratulations to medical students at UNMC and across the country as you celebrate and take the next steps toward becoming the future of medicine. No matter the result, you have come this far and you will continue to step forward as a physician into a realm of extraordinary opportunity to witness, and care for humanity, with all of it’s vulnerability and complexity.

From the UNMC ID Division, we wish you all the best and of course, we hope to see you join us again as fellows!

New Staff Spotlight – Danny Schroeder, PharmD

Tell us about the position you are starting:  I have recently started my role at Nebraska Medicine Bellevue as an Antimicrobial Stewardship pharmacist. I reach out to physicians at Nebraska Medicine Bellevue to discuss antibiotic therapy and try to obtain the best and safest therapy for our patients here. In addition, I work with Dr. Jasmine Marcelin in this role, she helps guide me with her expertise on some of Bellevue’s more complicated patients.

Tell us about your background:  I was born and raised in Omaha, Nebraska. I completed my pre-pharmacy studies at the University of Nebraska at Lincoln and came back to Omaha and obtained my PharmD in 2012 at the University of Nebraska Medical Center College of Pharmacy. I started at Nebraska Medicine Bellevue right after I graduated in 2012 as a casual pharmacist and started my full time position at Bellevue in early 2013.

Why UNMC? I obtained my PharmD at UNMC so I already knew how great of an organization UNMC is. I knew once I graduated that if I had a chance to get a position at UNMC I would take it. Everyone I know that works for the organization is happy working here and I enjoy working with all of the staff from UNMC as well. I also have an interest in teaching so working at an academic institution can help me pursue that interest.

What about ID makes you excited?  As I have been working at Nebraska Medicine Bellevue I found that the patients that have interested me most have been patients with infections. Progress notes from ID attending physicians have always been my favorite notes to read because it is fascinating to me how they go about figuring out what is wrong with their patients. I am excited to join the detective crew and do my part to help tackle these cases. In addition, I feel like I learn something new in the ID realm every day, there are advancements and new therapies introduced often and I am always eager to learn new treatment mechanisms.

Tell us something interesting about yourself UNRELATED to medicine: I really enjoy having a good beer. My wife and I traveled to Germany in 2016 and we attended an Oktoberfest celebration in Stuttgart. I also enjoy outdoor activities like hiking and disc golf. Lastly, I am a dog person, my wife and I have two Shih Tzus and they take up a lot of our time!

 

Danny Schroeder is joining the Nebraska Medicine Antimicrobial Stewardship Program (ASP) Team as an ASP Pharmacist primarily located at our Bellevue campus. We are pleased to have the opportunity to add this ASP complement to our Bellevue campus – Danny has been a great asset to the team.

Stewardship-driven Ertapenem Restriction: Can Reduced Utilization Affect the Antibiogram?

In this article review we learn about the impact of a large-scale, multi-institutional Antimicrobial Stewardship Intervention on significantly reducing the overall use of ertapenem without subsequent downstream effect on carbapenem-resistant Enterobacteriaceae (CRE) non-susceptibility patterns.

Delgado A, Gawrys GW, Duhon BM, Lee GC (2017). Impact of an Antimicrobial Stewardship Initiative on Ertapenem Use and Carbapenem Susceptibilities at Four Community Hospitals. J Infect Dis Ther 5: 341. doi:10.4172/2332-0877.1000341

Ertapenem has no activity against Pseudomonas spp. isolates, and although there is a theoretical risk of increasing carbapenem resistant Pseudomonas spp. isolates with ertapenem use, clinical studies have demonstrated that this is not the case.  Nevertheless, ertapenem use can potentially select for CRE, and there remains clinical value in minimizing its use.

The authors conducted a retrospective pre-post quality improvement study designed to reduce ertapenem usage, hoping to also demonstrate an effect in the prevalence of resistant Pseudomonas spp. and Enterobacteriaceae as a result of this intervention.  The multifaceted stewardship intervention was largely educational, but was supported by modification of electronic orders and providing audit-feedback opportunities to high frequency prescribers. They also included as a counter measure, evaluation of use of other alternative antimicrobials.

They were successful in significantly reducing ertapenem utilization by 60% with mean days of therapy (DOT) per 1000 adjusted patient days declining from 17.6 to 7.0, p<0.001. There was a decrease in overall antibiotic use but as expected, ceftriaxone and fluoroquinolones were highly utilized and increased around October 2014 (3 months after electronic alert restricting ertapenem).  They reported stability of carbapenem use as a class.  They only reviewed Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae isolates; so potential effect on other Enterobacteriaceae could not be assessed. There was no change in % of P. aeruginosa non-susceptibility to carbapenems, however the average incidence of carbapenem non-susceptible P. aeruginosa isolates per 10,000 adjusted patient days decreased from 4.9 to 3.7 (p=0.03). There were no changes in % or average incidence of carbapenem non-susceptible E. coli or K. pneumoniae.

The authors achieved the goal of reduced ertapenem usage from 18.3 to 5.1 DOT, but did not show an associated change in carbapenem non-susceptible organisms. Furthermore, their overall carbapenem use was stable (though appears to have slightly trended upwards on the graph) despite significant ertapenem utilization reductions; without a breakdown of individual carbapenem use, it is impossible to know if there was a concordant increase in imipinem/meropenem use to account for this.  Antibiotic shortages occurred during the study period, which unfortunately adds a confounder to the overall reduction of antibiotic utilization, as well as overall carbapenem utilization. – could these shortages have caused an increase in meropenem use? Additionally, limited (though number not specified)  carbapenem non-susceptible isolates at baseline makes it difficult to draw conclusions about effect of the intervention on the antibiogram. However, it demonstrates well that a multifaceted intervention can have significant impact on antibiotic utilization.
