I recently listened in to a Webinar related to infectious disease prevention strategies in elementary schools. The lead speaker (Dr. Thomas Sandora) was the principal investigator of a research study that was sponsored by Clorox and published in the Journal, Pediatrics a few months ago. I thought the results were interesting.
Study Design
This study was a randomized, controlled trial of 285 third to fifth graders in a school in Avon, Ohio. The study took place over a two-month period: from March to May, 2006. Half of the classrooms were randomized to the intervention group (which included having the kids apply hand sanitizer before and after lunch, and the teachers perform a sanitary wipe down of all their desks once/day), the other half were observed during their “business as usual” daily routine without sanitizers. The primary outcome measure was “days of school missed due to illness – either upper respiratory or gastrointestinal.” Swabs of surfaces in both the intervention and control groups were taken.
Results
Interestingly, there was no difference in the groups in terms of days of school missed due to upper respiratory type illnesses. There was a small but significant (9%) reduction in gastrointestinal-related illnesses absenteeism in the intervention group. Surface swabs picked up norovirus with higher frequency in the control group classrooms. No MRSA was detected during the study.
Discussion
Upper respiratory tract infections (URIs) are highly contagious, and are commonly spread by droplets in the air as well as surface contact (some viruses and bacteria can survive for 2 hours or more outside the body). Due to an infected child’s continuous contact with their own nasal secretions (sorry for the graphic photo), it is difficult to reduce the spread of URIs through the occasional hand washing or sanitizing. One would have to wash a child’s hands after each time they touched their mouth or nose.
On the other hand, gastrointestinal infections like norovirus are spread via the fecal-oral route, and are therefore not dripped and sneezed all over the place the way URI-causing viruses tend to be. Instead, GI infections are spread when hands are not washed thoroughly after a trip to the bathroom – and then food is touched and ingested.
So it’s not all that surprising that the transmission of GI-related infections were particularly susceptible to this study’s intervention: hand sanitizing before and after lunch, and a daily desk surface wipe.
An interesting point that Dr. Sandora made was that alcohol-based hand sanitizers don’t contribute to antibiotic resistance, because their killing mechanism is not related to antibiotics. I guess it’s like saying that humans don’t become resistant to knife injuries when exposed to attacks with greater frequency.
Conclusions
Hand sanitizer and surface disinfectant strategies may be more effective in reducing the transmission of gastrointestinal illnesses than respiratory tract illnesses in elementary school children. But since compliance is challenging – the total reduction in GI illness transmission remains modest though probably worth the hygiene effort. One glance at the photo above tells you all you need to know.

The blogosphere has been buzzing lately about the idea of “fecal transplants,” probably because this treatment (first studied in the 80’s) was recently mentioned on Grey’s Anatomy. Proponents of the therapy (which involves the introduction of donor stool into a patient via enema or naso-gastric tube) say that it can rejuvenate intestinal flora and cure c. diff colitis, and various inflammatory bowel disorders. I had my doubts about these claims and decided to interview gastroenterologist Dr. Brian Fennerty to get to the bottom (sorry abou the bad pun) of this issue.
Dr. Fennerty is a Professor of Medicine in the Division of Gastroenterology at Oregon Health & Science University in Portland, Oregon, where he also serves as Section Chief of Gastroenterology.
Listen to the podcast here:
[Audio:http://blog.getbetterhealth.com/wp-content/uploads/2008/11/brianfennertyfecallq.mp3]
Dr. Val: What exactly is a “fecal transplant?”
Dr. Fennerty: First, by way of background, you need to understand that the GI tract is populated with thousands of varieties of “good” bacteria that are essential for our health. If we didn’t have bacteria in our colon and small intestine, we would die. Fecal transplantation is the repopulation of a person’s gut bacteria (flora) with fecal matter from somebody else. Some argue that this helps to treat certain diseases.
Dr. Val: How is this procedure performed?
Dr. Fennerty: As it was originally described, fecal transplantation involved removing the undigested food particles from the stool sample of a “healthy” person, and then spinning it so that a pellet (of hundreds of thousands of species and quasi-species of bacteria) remains. The pellet is then introduced to the patient through a nasogastric tube into the small intestine, or the pellet can be resuspended in liquid and introduced into the rectum via an enema. The idea is that the bacteria will colonize the patient’s colon and squeeze out the bad bacteria that are in there.

I posted this true story on my blog previously, but I think it bears repeating (especially with the recent news of increased violence against physicians and threats at gunpoint). Details of the story were altered to ensure privacy of all involved.
***
The son of a business tycoon experienced some diarrhea. He went to his local emergency room immediately, explaining to the staff who his father was, and that he required immediate treatment.
Because of his father’s influence, the man was indeed seen immediately. The physicians soon realized, however, that there was nothing emergent about this man’s complaints. After several blood tests and a stool sample were taken, he was administered some oral fluids and monitored for several hours, they chose to release him to recover from his gastroenteritis (stomach flu) at home.
The man complained bitterly and said that he wanted to be admitted to the hospital. The physicians, with respect, explained that he didn’t show any signs of dehydration, that he had no fever, his diarrhea was indeed fairly mild (he had only gone to the restroom once during the hours of his ED visit – and that was when he was asked to produce a stool sample). The man’s pulse was in the 70’s and he had no acute abdominal tenderness.
The man left in a huff, and called his father to rain down sulfur on the ED that wouldn’t admit him.
And his father did just that.
Soon every physician in the chain of command, from the attending who treated him in the ED right up to the hospital’s medical chief of staff had received an ear full. Idle threats of litigation were thrown about, and vague references to cutting key financial support to the hospital made its way to the ear of the hospital CEO.
The hospital CEO appeared in the ED in person, all red and huffing, quite convinced that the physicians were “unreasonable” and showed “poor judgment.” Arguments to the contrary were not acceptable, and the physicians were told that they would admit this man immediately.
The triumphant young man returned to the ED for his admission. Since the admitting diagnosis was supposedly dehydration, a nurse was asked to place an IV line. The man was speaking so animatedly on his cell phone, boasting to a friend about how the doctors wouldn’t admit him to the hospital so his dad had to make them see the light, that he moved his other arm just at the point when the nurse was inserting the IV needle. Of course, the poor woman missed his vein.
And so the man flew into a rage, calling her incompetent, cursing the hospital, and refusing to allow her to try again.
At this point, the ED physicians just wanted him out of the emergency room – so they admitted him to medicine’s service with the following pieces of information on his chart:
Admit for bowel rest. Patient complaining of diarrhea. Blood pressure 120/80, pulse 72, temperature 98.5, no abdominal tenderness, no white count, patient refusing IV hydration.
Now, this is code for: this admission is total BS. Any doctor reading these facts knows that the patient is perfectly fine and is being admitted for non-health related reasons. With normal vital signs, and no evidence of dehydration or infection, this hardly qualifies as a legitimate reason to take up space in a hospital bed. And when the patient is refusing the only treatment that might plausibly treat him, you know you’re in for trouble.
The man was discharged the next day, after undergoing (at his insistence) an abdominal CAT scan, a GI consult, an ultrasound of his gallbladder, and a blood culture. His total hospital fee was about $8,000.
Do you think he paid out of pocket for this? No. He submitted the claim for payment to his insurance company. Their medical director, of course, reviewed the hospital chart and realized that the man had no indication for admission, and refused medical care to boot, so he denied the claim.
So the son appealed to his father, who then rained down sulfur on the insurance company, threatening to pull his entire business (with its thousands of workers insured by them) from the company if they didn’t pay his son’s claim.
The medical director at the insurance company dug in his heels on principle, assuming that if he continued to deny the claim, the hospital would (eventually) agree to “eat the cost.”
In the end, the insurance company did not pay the claim. The CEO of the insurance company called the hospital CEO, explaining that it was really the doctor’s fault for admitting a man who didn’t meet admission requirements. The hospital CEO agreed to discipline the physician (yes, you read that corretly) and eat the cost to maintain a good relationship with the insurance company that generally pays the hospital in a timely manner for a large number of patient services.

I recently met with Tim Turnham, CEO for the Colon Cancer Alliance, to find out what’s been going on in his neck of the woods. He presented me with one of the best non-profit marketing pitches I’ve seen in a long time. His team is organizing a series of races designed to raise support and awareness for colon cancer. The theme? Running the race in your boxer shorts. The title:
The UNDY 5000: A Brief Run To Fight Colon Cancer (see image of Indy 5000 flags made of boxer shorts)
Become an UNDY 5000 sponsor today… because time is short.
I love it.
If you or your organization would like to sponsor a race, check out this website or contact Fran Campion Watson, Director of Events at the Colon Cancer Alliance. Phone: 202-731-0122.
I hope that proceeds will go towards research that will help friends like mine who are battling colon cancer.
For more information about colon cancer (from one of the nation’s prominent researchers) check out Dr. Heinz Josef Lenz’s colon cancer curriculum at Revolution Health.This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.
