Cell Phones May Spread Infections

CHaN_316 writes "Yahoo is running an article talking about how cell phones from health workers are helping spread dangerous infections in hospitals. 'They found that 12 percent of healthcare providers' cell phones were contaminated with [Acinetobacter baumannii]. The results are disturbing because [it] has the propensity to develop resistance to almost all available antibiotics ... Cell phones provide a large dry surface that allows survival of A. baumannii--it requires no nutrients ... [it] is found in intensive care units, and the mortality rate among infected patients is very high -- between 50 and 60 percent.' The hospital that conducted this research no longer allows the use of cell phones, and are switching to devices that don't require hand contact like pagers." So how long before someone develops a cell phone that can be dunked in alcohol or run through the autoclave to sterilize it?

    Actually, you can sterilize just about anything but the cost and time are prohibitive. There is a sterilization process that uses gas where I have sterilized entire computers, monitors, mouse and keyboards that were placed in operating rooms. Also I have sterlized sensitive electronics that could not take either pressure or temperature that survived gas sterilization just fine. It is a trade off between cost of the sterilization process, the time it takes the equipment to be done, and the usefullness of the equipment.

    Well, you can't autoclave it. They usually only do this with certain metals, since they can withstand the heat involved.

    You could theoretically dip it in a biocide of some sort (they use stuff tougher than alcohol in operating rooms and on used surgical tools) but there's a "nook & cranny" problem. When designing non-metal surgical tools, you have to make sure you don't make any tiny cracks, holes, or grooves where stuff can cling and avoid the biocide. The last cell phone I saw had a lot of nooks and crannies. You'd possibly need to redesign one to be completely sealed, which is getting more feasible because of wireless battery charging technologies and wireless connectivity technologies.

    Another alternative is that you could stick it in a sterile container and use it wirelessly, but then your wireless headset would still need to be sterilizable.

      I couldn't agree more. When I did my alternative civilian service [Zivildienst] in a sheltered workshop [Werkstatt fr Behinderte], the handicapped people built the wiring harnesses for medical autoclaves from wire and crimp contacts. We had to rework the wiring harnesses several times, because the wires (mainly their electric insulation) and the contacts did not stand the conditions (heat and humidity) inside the autoclaves. The contacts corroded, the insulation melted or broke and caused short circuits, and so on.

      Those parts were specified for this hard conditions (but they actually did not met the specifications). Now guess what happens to a mobile phone that is certainly not designed for that conditions if you put it inside an autoclave.

      You may find some more information about autoclaves at the web site of the company we worked for: www.melag.de (english pages available). (I'm no longer related with that company, it's just the only company I know that produces autoclaves.)

    I thought people were not supposed to use cell phones in hospitals. Why are they even there?

    There was some panic over this early on, but it turned out to be a minimal issue.

    When I was working at a hospital, we did some testing of cellular devices and medical equipment. See, medical equipment gets an exemption from the regular FCC shielding requirements for some historical reason, and we all know if you're broadcasting interference you're an antenna too, and you don't have to accept interference if you're a medical device.

    That said, abuse isn't as rampant as assumed. With older analog phones (higher wattage) the only device found to be a problem was a ventilator device within about 6' of the cell phone, IIRC.

    What's not terribly intuitive is that one of the best ways to deal with the problem is to work with a cellular provider to put a 'tower' right on the hospital. If the tower is that close, the phones need to use far less power to broadcast, hence less interference. The new digital units are all lower-powered to begin with too, so the problem is further decreased.

    So, if you're going to visit a friend in the ICU, make sure you turn off your phone before going into the patient's room, but if you're sitting in the waiting room, it's not likely you'll cause problems.

    "Possibly, but what the hell are medical staff doing with cell phones on them in the first place while they're on the job, working with patients? "Hi, sorry, I'm smack in the middle of cracking open someone's ribcage, can I call you back?""

    There are a lot of different answers to this question because the term "medical staff" covers a lot of different people with different functions.

    Surgeons take calls during procedures. They always have, long before there were even cordless phones, much less cell phones. Medical treatment is sometimes dependent upon the rapid dispersal of information and an equally rapid decision being made in response to said information. I've talked to more than a few chest surgeons on the phone while they had their hands in someone else's chest. This was accomplished (aseptically) by speaker phone.

    With the advent of cell phones, many health care providers who care for patients dependent upon rapid decision-making carry cell phones with them 24/7/365. This easy access to decision-making resources has saved lives and reduced suffering, but these people represent a tiny, tiny fraction of the health care workers carrying cell phones today.

    Having said that, health care workers are people first, and there exists roughly the same proportion of stupid, thoughtless people in the industry as exist in the world at large. So, many health care workers use phones thoughtlessly. Should they stop? Sure.

    Wedding rings are virtual cesspools of virulent bacteria, particularly if they are engraved and/or contain a complex setting. Do you have any idea how difficult it is to get people to take off their wedding rings while working in ICU's even though we have reams of good, hard science demonstrating that rings are a very efficient way to infect patients with all kinds of deadly bugs? Forget cell phones, it's just another surface, just another pathogen vehicle. It's just a particularly powerful vehicle because people touch it with their hands.

    I despise cell phones only slightly more than I despise strollers. They are both a menace to civility in public space. But, there's nothing new here. My point is the cell phone problem discussed in this story, and all other similar hand-contamination vectors (past, present and future) can be stopped dead with 15 seconds of hand-washing. Just using running water , i.e., without soap, is almost as effective. It's not hard, it's just inconvenient.

    It really comes down to hand-washing.

    If you wash your hands between patients (and especially before going to see someone who's immune system has taken a hit... chemo, HIV, SCID, etc, etc), you'll cut down dramatically on the spread of disease.

    The nosocomial, or hospital-acquired infections are the worst actors... multiply-resistant, and prevelant in the one location where sick and vulnerable people are gathered in one place.

    This doesn't leave out healthcare workers. Your own commensal organisms that live on your skin and in your gut tend to be wild-type, and less-resistant than nosocomials.... until you wipe them out by doing something dumb, like taking antibiotics for an infection that's viral, or would clear up on its own given a little time (mild sinusitis, for example). This is why I advocate avoiding antibiotics unless clearly indicated... this includes taking antibiotics for infections that would get better with good wound care alone... like boils and smaller cutaneous abscesses. If you work in a health care facility, your normal bacterial population is the only thing protecting you from mass colonization with resistant bugs, particularly if you work with critically-ill patients. You don't want to get really sick with something, then find out there's nothing that can treat your infection... I've seen it happen to too many patients.

    So yes, wash your hands... and don't take antibiotics unless you damned well NEED them... If I personally get sick, and all the antibiotics are going to do is shorten my disease course by a day or two, I'll skip them... I'm not sacrificing my precious normal flora for such a minimal gain.

    The problem with antibiotic abuse in health care workers is particularly troubling, as you describe. I'm like you, I don't take them unless my clinical situation indicates it--meaning I have the right drug for the right bug and I'm getting worse instead of better.

    Don't even get me started on anti-bacterial soaps.... Not only does their misuse compound the problems we've discussed above, but these soaps only kill off the same flora that our antibiotics (particularly the cheap and safe ones) do, leaving the drug-resistant flora relatively unaffected. As they get washed into our communal water-treatment facilities, the drug-resistant strains are then left with reduced competiton for the limited, consumable resources (like food) that they need to live and multiply.

    Because of the use of the "New and Improved Anti-bacterial ____," we encourage the survival and colonization of the very bugs that cause the illnesses for which we don't have good and/or cheap antibiotics. I particularly regret seeing antibacterials used routinely at home around infants, which is the use for which they are most aggressively marketed....

    This "news" is unnecessarily alarmist. Acinetobacter baumannii usually doesn't cause infection in healthy individuals. Notice that they did this study in the intensive care unit, where they've known for a while that patients get this sort of infection. The patients might have open wounds or burns. Their immune systems tend to be shot to hell, from, for example, chemotherapy, HIV, some other illness, or just from the high levels of cortisol in their blood because of stress from, e.g., the extreme amounts of pain and/or respiratory distress they are in.

    From Harrison's Princples of Internal Medicine 15th edition, 2001:

    Acitenobacter is highly prevalent in the environment. It is found in most water and soil samples and has a wide habitat. Acitenobacter has been cultured from the moist skin of healthy humans; increased colonization of the skin and the respiratory and gastrointestinal tracts occurs in individuals in long-term-care facilities and hospitals. Reservoirs for acquisition in these settings include health care personnel, medical equipment, food, and the surrounding environment. Infections in healthy people in the community are unusual, but a few reports of pneumonia have been published. The overwhelming majority of infections are acquired in the hospital and long-term-care facilities.... Acinetobacter species account for 1 to 3% of hospital-acquired infections and affect primarily immunocompromised hosts and patients with comorbid disease. ICUs are a prominent site of Acitenobacter infections.

    The problem with this is that any radiation (UV, X-ray, hard gammas) that you might choose to use to sterilize the telephone will also likely degrade the plastic from which it is constructed.

    Depending on the particular composition of the telephone, radiation may cause either brittleness or softening of the plastic case and buttons. The clear display window will probably yellow or cloud, before failing completely. I would anticipate that there is potential for damage to the LCD itself, but that's not one of my areas of expertise.

    Also, UV is extremely vulnerable to nook-and-cranny failures. Any part of the phone that is potentially shaded--around buttons, holes in the speaker or microphone grille--can protect bacteria from UV exposure. Actually, just a little bit of dirt or dust can provide sufficient shade to permit bacteria to survive. UV works quite well on airborne pathogens, but surfaces must be carefully designed with UV sterilization in mind.
