[Intl_DxMedPhys] For Ohio physicists

[Ryan Fisher]

FWIW we have also not shared the rule update with our providers or OR management and don’t plan to do so. I’ll be happy to discuss why we’re not changing anything policy-wise with anyone who happens to dig into the rule update, but seeing as I wasn’t even aware of this change until after it was published I doubt our ortho surgeons are going to find out any time soon?

Apparently so. One physicist who attended the meetings contacted me off-list and invited me to contact him directly so he could explain the thought processes that went into that decision. I haven’t done that yet. I shared this with my radiology

I shared this with my radiology directors and am recommending that they do not share this information with the OR management. For the five hospitals where I’m IRRP (IRRP is Ohio-speak for RSO of radiation generating equipment), I have the authority to flat out refuse to accept this option, and that’s what I’m doing.

On the whole I think this is a bad idea.  Principally because those who are aware of this loophole will pressure their MPs or RSOs to implement this even if the MP or RSO is concerned about compliance and managing adherence to the recommended limits.  Did the MPs on the state advisory board participate in discussions prior to this rule change?

Hi Bob,

I echo your concerns and sentiment. Additionally, as you know, the ODH claims that it is the operator of a fluoroscope who is responsible for the safety of the persons present (and exposed) during fluoroscopic imaging. How are they supposed to know who does or doesn't require lead protection? And, if those individuals have occupational dosimetry, they will clearly need to have different dosimeter processing without EDE correction since they won’t be wearing lead apparel (unlikely site will pay attention to that and leave it on).

If there is any silver lining it is that a radiation expert must provide the documentation and parameters for implementing this allowance, and we should have the right to not provide such evidence and state that it is not acceptable in our professional judgement. I realize on the consulting side it may be trickier to take that stance. Even if provided though, the site will have to have administrative controls in place to monitor compliance (also not going to happen) otherwise jeopardize their compliance.

All the best,
Kevin

Sorry for clogging up an international list for an Ohio-specific question, but others may have input as well. New ODH regulations that went into effect last month now allow personnel participating in fluoroscopic procedures to be present in
Sorry for clogging up an international list for an Ohio-specific question, but others may have input as well.

New ODH regulations that went into effect last month now allow personnel participating in fluoroscopic procedures to be present in the procedure room without a protective apron if the physicist provides time and distance limitations. In other words, I can do calculations and allow certain members of OR staff to be in surgery cases as long as they stay at least X meters away from the table for no more than Y minutes of fluoro per week. Here’s the new reg:

“Any individual who is in the room during the fluoroscopic procedure will be adequately protected by standing behind a whole body protective barrier or will wear a protective lead apron of not less than 0.25 millimeter lead equivalent. If a handler's radiation expert includes documented evidence and specifies in the quality assurance program a distance and time interval in the room from the source at which an individual is unlikely to receive a total effective dose equivalent of greater than two millirem in any one hour or one hundred millirem in a year, the handler can forgo the use of a protective barrier or lead apron for that time at that distance.”

My first comment is, “Are they serious?!!??” I see this as a nearly impossible option given that the responsibility will ultimately fall on us to show that we track the movements and exposure of these individuals exempted from wearing lead aprons. Also, the time / distance limitations are moving targets. Someone can be 3 meters from table for a longer time than 2 meters. And how is the unshielded person supposed to keep track of fluoro time?

Even if there are personnel that we can exempt from wearing aprons because they pop in and out of OR’s for short periods, I can see, down the road, inspectors looking for some sort of tracking to verify that they are not overstaying their allowed exposure time.

Are any Ohio physicists planning to take advantage of this new regulation? And if so, how are you addressing the issues I mentioned?
