New Lab Matters: Sharing the value of public health laboratories

New Lab Matters: Sharing the value of public health laboratories |

The need for a laboratory voice in budgetary discussions has become more urgent recently, and “human-to-human relationships” are as critical as technical knowledge. So how does a public health laboratory raise its profile within the community? By telling a good story…over and over again.

In the summer issue of Lab Matters, our feature article examines how laboratories are sharing their value, one interview, photo or outreach moment at a time.

Here are just a few of this issue’s highlights:

Fighting antimicrobial resistance requires clinical and public health response

Fighting antimicrobial resistance requires clinical and public health response |

By Kelly Wroblewski, director, Infectious Disease Programs, APHL

They may be invisible to the naked eye and their names may be hard to pronounce, but antimicrobial resistant bacteria – bacteria that don’t respond to common antibiotics – pose a serious threat to the public’s health that is impossible to ignore. Until recently, antimicrobial resistance was seen as a problem to be addressed at the patient or healthcare facility level where the impact on the lives of people was immediately visible. Testing, responding to and controlling antimicrobial resistant pathogens was not often seen as something that fell under the purview of public health. But that’s finally changing.

I began my career as a clinical microbiologist. My first job was the lead micro technologist in a small hospital laboratory in a rural area at a time when hospital acquired MRSA – or “nosocomial MRSA” –rates had doubled. I still think about a specific case, an eight-month old baby girl who was a patient in the ER. I drew her blood myself, brought it to the lab and immediately inoculated it into blood culture bottles. A few days later, I was the person to isolate and identify MRSA in her sample. Several weeks after she had been transferred to a hospital with more advanced pediatric care, I saw her obituary in the paper.

MRSA control was a significant focus for the hospital where I worked. Because we were a small hospital, it was easy to keep track of patients who presented with MRSA, something I began doing shortly after starting my job. The patient population was mostly elderly and we often admitted, discharged and readmitted patients from the community’s three long-term care facilities and one rehabilitation center. It quickly became clear that the frequent transfer of patients between facilities was contributing to MRSA rates in the entire county. (Patient transfers between health care facilities is a well-known source of antimicrobial resistance spread.)

The hospital was able to work with the other facilities to implement infection control strategies to control (but not eliminate) the problem. This was possible because our small community allowed for open communication between healthcare facilities and meant that all testing was occurring in a single microbiology laboratory. Coordination of this sort of response and control effort would be much more difficult in a more populous area without external monitoring and assistance. This is where public health can and should play a vital role.

That is finally going to change.

In the coming year, public health laboratories will play a critical role in the Obama administration’s National Action Plan to Combat Antimicrobial Resistance. One of the initial roles for public health labs was announced by CDC last week: the launch of the Antimicrobial Resistance Laboratory Network (ARLN). Seven public health laboratories have been chosen to provide testing in support of a national surveillance system that will monitor and respond to drug resistance throughout the country. This fall the chosen laboratories will receive training and begin implementing highly specialized tests that will allow them to respond to outbreaks, characterize and track different mechanisms of resistance, and to detect new kinds of resistance in the pathogens that most concern public health officials. All 50 state labs, DC and several large local labs will also be implementing testing to confirm and characterize carbapenem-resistant Enterobacteriaceae (CRE), which has been described as one of the most urgent threats to public health.

APHL looks forward to assisting CDC in the roll-out, training and coordination of this laboratory network in the coming months. My colleagues and I are eager to see the impact of the ARLN on antimicrobial resistance surveillance and response activities

While no one will ever know if the ARLN or other new public health measures would have prevented that baby girl from contracting and succumbing to MRSA, I am optimistic that the network represents a significant step forward.

The isolate on the left plate is susceptible to the antibiotics on the discs and is therefore unable to grow adjacent to the discs. The plate on the right was inoculated with a carbapenem-resistant Enterobacteriaceae (CRE) bacterium that proved to be resistant to all of the antibiotics tested and is therefore able to grow near the discs.
