Are Your Sterile Implants Really Sterile?

Are Your Sterile Implants Really Sterile?

 

I have been on both sides of patient safety for over 13 years.

On the one side, I am a harmed patient who suffered a multitude of adverse events stemming from pharmaceuticals and medical devices, including contracting Methicillin-resistant Staphylococcus aureus (MRSA) and Sepsis. In addition, I have had over 3 dozen surgeries, some of them resulting in errors and infections.

On the other side, I am a Special Government Employee (SGE) at the U.S. Food and Drug Administration’s Center for Device and Radiological Health (CDRH). As the consumer representative on the Advisory Committee, my role is to analyze scientific data, understand research design, discuss benefits and risks, and evaluate the safety and efficacy of medical devices under review.

I was recently contacted via LinkedIn by Dr. Aakash Agarwal, Director of Research and Development for Spinal Balance Inc. at the University of Toledo to tell me about the growing problem of device contamination. After a brief phone call, Dr. Agarwal sent me research literature. I was alarmed by what I read and I feel that this matter needs to be brought to the public’s attention, including patients, physicians, and regulators. I agree with Dr. Agarwal that a public hearing needs to be held at the FDA to discuss the pedicle contamination. This is a matter that is not talked about and it should be.

Pedicle screws are used in spinal fusion surgeries to add extra support and strength to the fusion while it heals. The screws are placed above and below the vertebrae that were fused. A rod is used to connect the screws which prevents movement and allows the bone graft to heal. They can become contaminated and it is a growing problem in the United States; a fact that most people don’t know.

Bacterial infections following spinal surgery are estimated at 12.7% according to Dr. Agarwal.

The average hospital bill following such infections is $63,000, with hospitalization being necessary in 5.5% of those cases.

Pedicle screws are the most common implant used in spinal fusion surgery. A surgeon will typically have over a hundred screws available for use during surgery, but actually uses a small amount.

The pedicle screws’ low usage rate leads to these screws being repeatedly reprocessed—or “automated washing with contaminated instruments from theatre and then sterilized without prior inspection by hospital staff” by the sterilization processing department (SPD).

In essence, these “sterile” implants, alarmingly, have been found to contain contaminants.

Furthermore, unused pedicle screws are subject to contamination during surgery.

Pedicle screws are linked to MRSA infections during their handling during the procedure, and during the reprocessing before and after surgery. MRSA is a bacterium that causes infections in different parts of the body and it is tougher to treat than most strains because it is resistant to some commonly used antibiotics. Re-processed screws have been found to harbor corrosion, biofilm, endotoxins, fatty tissue, and soap residue mixed with fat, whereas exposed pedicle screws in “sterile-field” become contaminated. These infections were present in at least 10% to 30% of patients with chronic pain and were detected only during revision spine surgery. I have these screws following spinal surgery and suffered infections as a result.

In order to keep pedicle screws from becoming contaminated, researchers are suggesting providing the implant in an individual sterile pack (single-use and ready for implantation), and each implant should have a functional guard around it to protect from direct exposure during handling. Dr. Agarwal and his colleagues co-authored a study to determine the magnitude of the issue, and how to prevent surgical site contamination linked to pedicle screws in spine surgery.

Dr. Agarwal explains it like this:  “The single center study as well as our multicenter study, showed that all unguarded screws resulted in bacterial contamination inside the “sterile field” during live surgeries, whereas guarded screws had no such contamination. The key constituents that define the pathogenesis of SSI (Surgical Site Infection) are the virulence, host-site immunity, and dosage. We demonstrated the preventative method effective on reducing the dosage of bacteria.”

The guards used on the single-use pedicle screw are commercially available.

Dr. Agarwal has filed a Citizens Petition with the U.S. Food and Drug Administration calling for a ban on the reprocessing of pedicle screws in the U.S. It is currently under review, a process which could take a year or longer. Agarwal requests “the Commissioner of Food and Drugs to cease clearing 510(k)s and approving PMAs [pre-market approvals] for reprocessing of pedicle screws and other implantable orthopedic devices and cease clearing 510(k)s for re-usable implantable orthopedic device[s].”

In addition to asking for the cessation of approvals for reprocessed pedicle screws and interbody cages, the petition requests that every implantable orthopedic device should be provided “such that it is not touched or exposed before implantation, by the operating room staff, in the sterile field.”

I am a patient who has undergone dozens of surgeries and have several medical implants. This is all information I wish I had known prior to my surgeries. Contamination is preventable and reprocessing needs to be banned.

Your life could depend on it.

Sepsis: This time it’s personal

Throughout my years in patient safety, I’ve been to many meetings, conferences, and summits. In those years, I’ve been introduced to patient safety leaders involved in reducing sepsis and raising awareness about it. Being in the field of antibiotic safety, my work often crosses with advocates regarding infection control.

I have these people to thank for saving my life.

I have to admit, prior to meeting them, I didn’t know what sepsis even was. But one thing that always stuck with me after the meetings was the phrase “Could this be sepsis?”.

I just found out how asking that question could save your life.

Let me back track a bit and explain how this became personal for me.

I broke my ankle in 3 places and ruptured 5 tendons. Repairing it required extensive reconstructive surgery. I had three incisions. Two weeks following the surgery, I developed an infection. The incisions were blistery, peeling, red, swollen, and leaking some kind of fluid. In addition, I had a very high fever. Taking the advice of a nurse friend, I had it checked out and I was treated for infection.

I didn’t give it a second thought until one day after physical therapy a few weeks later. Later that night, my ankle was red, swollen and leaking. I wasn’t alarmed about it until I had the chills so bad that it looked like I was having a seizure. My breathing and heart rate became rapid and I was hallucinating.

This felt different than the last time I developed an infection.

I went to Carolinas Medical Center in Charlotte, North Carolina.

I remembered that crucial phrase from my meetings, “Could this be sepsis?”

I didn’t realize I’d said it out loud until someone said “Yes, it could”.

Code Sepsis was called.

For those who don’t know, Code Sepsis is a protocol in which a patient is given fluids and antibiotic therapy within three hours of triage. For their compliance with Sepsis protocols, Carolinas Healthcare System was named a 2015 Sepsis Hero by the Sepsis Alliance.

I met several people from the Sepsis Alliance over the years. Thanks to the protocols they helped implement, I survived sepsis. It is not lost on me that I developed- and survived- sepsis during the month of September, which is Sepsis Awareness Month.

From what we can piece together, one of the three incisions was not healing properly and it opened me up to infection. I contracted MRSA at a physical therapy facility. It then turned into Sepsis. Luckily it was caught early and I was home within the week.
