IDWeek was held this year from Oct 8 to 12, 2014 in Philadelphia. IDWeek is the combined annual meeting of the Infectious Diseases Society of America (IDSA), the Society for Healthcare Epidemiology of America (SHEA), the HIV Medicine Association (HIVMA), and the Pediatric Infectious Diseases Society (PIDS). Given its wide ranging audience, there are many targeted streams that allow a range of topics. The abstract sessions featured over 1700 posters and are now already published and available in Open Forum Infect Dis (Fall 2014) as well as the abstracts from the oral presentations.
I have decided to create ‘buckets’ to best capture the various conference topics that I attended (Global outbreak threats, Surveillance in the hospital and the community, Infection control topic by topic, and Future issues for infection prevention). You will notice an emphasis on the Infection Prevention and Control (IPC) aspects of the sessions that are summarised. Please blame this on the fact that my bread is buttered this way!
Global outbreaks threats
Ebola dominated the conference, starting with the jam-packed first talk by Dr Robert Fowler on behalf of the World Health Organization. He shared personal experience of caring for patients in Sierra Leone and supportive care measures that can be implemented in resource-poor settings. This was followed by Bruce Ribner, MD, MPH, of Emory University his talk the Opening Special Plenary Session titled Treating Patients with Ebola Virus Infection in the U.S.: Lessons Learned  addressed the unique challenges of how to manage Ebola cases. Dr Ribner drew from the experience at Emory and highlighted all the relevant issues that need critical considerations (see summary of talk). He also mentioned that the PPE type, though important, is part of a multimodal approach to infection control and therefore encouraged healthcare facilities to prepare and practice for the potential of receiving an Ebola patient.
It has been two years since the first global cases of MERS-CoV were first reported . Dr Tariq Ahmed Madani, from the Ministry of Health, Saudi Arabia, in a talk aptly titled: “MERS Coronavirus – The Second Year” shared what he felt are the main problems that caused the uncontrollable outbreaks in hospitals. He condensed it to three points; i) overcrowded emergency departments, ii) suboptimal infection prevention practices, and iii) atypical presentation of patients. He proceeded to show evidence of camel to human transmission of MERS-CoV .
Surveillance in the hospital and the community
An entire symposium was dedicated to the revision of strategies to prevent healthcare-associated infections in acute healthcare titled ‘The Compendium’ . A couple of interesting points were shared under the banner of the symposium.
- Dr Deborah Yokoe’s talk “Highlights of the Compendium of Strategies to Prevent Healthcare-associated Infections in Acute Care Hospitals: 2014 Updates”  shared the complicated collaborative process involved in updating the 2008 recommendations  on Hand Hygiene, Clostridium difficile, CLABSI, CAUTI and VAPs.
- Dr Michael Howell in his talk “From VAP to VAE: Preventing Complications of Mechanical Ventilation” stated the confusion surrounding VAP surveillance is causing incomparable surveillance patterns. Instead of the CDC VAP definition, he offered the alternative, i.e. Ventilator Associated Events (VAE), which the audience felt was a more objective and measurable way of establishing harm related to ventilators .
An entire session was dedicated to how technology is now being used to conduct surveillance and gather information on outbreaks. For example, Dr John Brownstein revealed how software applications that are used daily by the public can allow Public Health institutions to predict outbreaks sooner than the current methods of conventional flu surveillance networks. He showed how from a cancelled dinner reservations  or public searches online one can deduce that influenza outbreaks are ravaging , also showing how a computer algorithm predicted the Ebola Outbreak before the WHO announced it.
Infection control, topic by topic
Clostridium difficile (Cdiff)
- Dr Tim Peto spoke about the Clinical Treatment and trials of Cdiff, sharing research about the use of whole genomic sequencing (WGS) in evaluating efficacy of new drugs against Cdiff. Dr Peto also partnered with Dr Derrick Crook in showcasing a myriad of applications of WGS, including as an outbreak management tool in infection control.
- Dr Colleen Kelly shared her study showing that Fecal Microbiota Transplantation appears to be a safe and effective treatment for recurrent, refractory, or severe CDI especially in a high-risk population of immunocompromised patients.
- Dr Curtis Donskey’s talk was on “Frequent transmission of Clostridium difficile by Asymptomatically colonized Long-Term Care Facility Residents during Hospital Admissions”. In his study, Donskey swabbed all long-term care patients on admission to hospital and realised that asymptomatic patients shed Cdiff spores and often can cause outbreaks . Dr Donskey reminded us of the need to ‘strategize’ on asymptomatic carriage of Cdiff.
- Dr Trevor Lawley (“Identifying commensal bacteria that provide resistance against Clostridium difficile Infection”) spoke about the advances in understanding of the microbiota in dealing with bacterial infections.
Healthcare cleaning & disinfection
- Dr Mark Rupp’s “Assessing Cleanliness and Motivating Environmental Service Workers” talk went through various auditing tools including microbiological methods, fluorescence monitoring and basic observation of staff cleaning. He also shared some new studies that show that positive attitude affects the quality of hospital housekeeping. He also shared a study that the time spent cleaning a hospital room does not correlate with the thoroughness of cleaning.
- Dr Deverick Anderson’s “Evaluating No-Touch Disinfection Systems” went through Ultraviolet, Hydrogen Peroxide Vapour (HPV) and self-disinfecting surfaces. Sharing his data on reducing UV room disinfection time as well as the data on the excellent efficacy of HPV he did caution adoption of impregnated surfaces citing research that more analysis is still needed.
Posters on cleaning & disinfection
- 1363 The Iowa disinfection cleaning project: opportunities, successes and challenges of a structured programmatic intervention in 56 hospitals.
- 1366 Surfaces closest to the patient have a higher multi-drug resistant organism (MDRO) bioburden on environmental surfaces in healthcare facilities.
- 1368 Assessment of environmental cleanliness in outpatient clinics – study showed that more work is needed in outpatient clinics.
Future issues for infection prevention
Stopping contact precautions on MRSA and VRE was a topic raised by Dr Michael Edmond and he covered elements that have been raised on his blog, and featured prominently at the SHEA conference earlier in the year. He concluded that with advances in hand washing and the use of chlorhexidine, there is no need to maintain contact precautions for MRSA and VRE. In addition, it was made clear during the conference that antimicrobial stewardship will play a huge role going forward in ensuring that the antibiotics that are in formulary will still remain effective.
As an Infection Preventionist, the talks offered plentiful choice and sometimes presented a challenge as to where to go since sessions of interest often ran concurrently. Unfortunately, as cloning is not widely available, I managed to stay in the loop about all talks of interest to me by following the #IDWEEK and #IDWEEK2014 hashtags on Twitter and Instagram, where attendees where tweeting from the various sessions allowing a more complete conference experience. I managed to make a lot of friends at ID Week 2014, and I am looking forward already to ID WEEK 2015!

Thanks Barley! A great summary. I feel like I was “almost there.” I must get to an ID Week!
Thanks Rodney. I absolutely loved the conference. Thanks for your kind words. Kudos to Jon for creating this knowledge sharing platform.
This is outstanding Barley, thank-you. As you know, I wasn’t able to make ID Week this year, so it’s great to have this resource.
It’s good to see that faecal microbiota transplantation continues to make waves in the professional community. It won’t be long now before it becomes standard of care for recurrent CDI, I’m sure.
Also, I am interested in the importance of asymptomatic colonization with toxigenic C. difficile. Could this be a big blind spot in our infection prevention and control approach? Put another way, is it time to start screening and isolating C. difficile carriers?
Then, of course, Ebola. It’s a shame in a way that the Ebola outbreak (important though it is) may be obscured the importance of some of the other aspects of the conference (not least the emergence of CRE), that represent a much more important ‘clear and present danger’ to healthcare facilities outside of West Africa!
There seems to be a strong trend, particularly in the US, away from targeted interventions towards universal interventions. I understand the logic here, but we need to be circumspect; indiscriminate use of biocides and especially antibiotics will cause more problems than it solves in the long term: http://www.micro-blog.info/2014/09/universal-vs-targeted-interventions-in-infection-prevention-and-control-the-case-for-a-targeted-strategy/
As cost goes down. I am all for swabbing for cdiff as patients come in. There seems to be a good case for this especially with asymptomatic carriers. I would donate to that cause.
