Quality Assurance and Performance Improvement
Concurrent Education Session - 60 minutes
Our aging population is escalating the need for orthopedic surgeries to replace injured and worn out knees, hips, and shoulders. Although many advancements in surgical techniques, implant designs, and improved material biocompatibility have reduced infection percentages over the years, the increase in prosthetic surgeries multiplies the number of patients at risk for serious infection. The alteration of the entire implant site, bacterial defense strategies, and protective actions along with the patient’s distracted immune defense reactions have only recently been better understood.
This session will discuss why only a few bacteria are needed to start an infection in the periprosthetic site, how the microbial invaders evade the patient’s immune defenses, and how they set up pathogen reservoirs to feed lingering or recurring infections. Participants will learn how better risk reduction practices for the patient before, during, and after surgery can reduce infections, readmissions, morbidity, and mortality.
Participants will hear a first-hand account from a patient who was affected by this issue, and who will relate his experience after several recurrences of periprosthetic infection following his hip replacement surgery. This real-life example will help emphasize how critical this issue is, particularly as facilities face escalating numbers of at-risk elderly patients requiring implant surgery while expanding antimicrobial resistance and pay-for-performance financial vulnerability increase the demand for more effective IPC.
We’ll also discuss new information on microcolony mutant surviving bacteria, the understanding of the role of treatments encouraging mutant strains and biofilm formation, hampered treatment efficacy due to tissue encapsulation, and how to prevent the progression to post-surgical complications. The need for adjustments in specimen processing techniques will be addressed, as will the critical role of device reprocessing.
Case studies will also be presented to help us relate with those living through the consequences of infections described in this course and to identify causes that could have been avoided.
