Elucidating the Mechanisms of Anesthesia

The Anesthesia Blog has tended to attract a certain tech-geek type of anesthesia provider.  We have attempted to cater to our audience by highlighting anesthesia tech products, smartphone apps and advances in our field.  Like many who sit and ponder about all things anesthesia, we’ve often wondered how anesthesia actually produces its desired effect?  Meyer-Overton was a nice thought but proven too simplistic.   Last we heard it had something to do with meddling with the lipid bilayer sandwich…but nobody seems to know for sure.

In a provocatively titled article in Scientific American called “What Doctors Don’t Understand About Anesthesia” we dive deeper into an interesting revelation into the effects of anesthesia on the brain:

Highlighting these fundamental gaps in knowledge, a group of researchers recently made a surprising discovery about how we transition out of consciousness and back. The common view holds that going under (induction) and coming back up (emergence) are the same process, albeit in different directions. However, a recent study published in the journal PLoS ONE suggests that going under is not the same as coming back up.

The researchers, led by Dr. Max Kelz at the University of Pennsylvania School of Medicine, observed that less anesthetic is required to keep the brain anesthetized than to induce unconsciousness. To explain these observations, the researchers have introduced a concept they call “neural inertia,” referring to the brain’s resistance to transitions between consciousness and unconsciousness. Elucidating the mechanisms of neural inertia could be critical to the task anesthesiologists perform every day, namely preventing patients from experiencing pain or awareness during surgery and in helping those patients who exhibit delays returning to the conscious state. This line of research could also provide insights into disrupted states of consciousness like coma.

Excellent work by Dr Kelz.  Thanks for adding to our understanding.

Update on the Company Model of Anesthesia Services

Guest post by Mark F. Weiss, J.D., Advisory Law Group

Background: The “company model” is the name given to a type of suspect anesthesia joint venture likely violative of the federal antikickback law. In its simplest form, it involves the creation of a business structure by the surgeons controlling the flow of referrals to an ASC in order to profit from the provision of anesthesia services at the facility. Read my article The Company Model: Is Making Less Money To Work at a Surgicenter Worth Jail Time? appearing in the January 2011 issue of Anesthesiology News and available on the articles page at advisorylawgroup.com.

It’s one thing to make a profit from medical practice – in fact, I’m more than all for it.

It’s quite another to extort a kickback for the referral of patients. That’s a crime. In connection with Medicare and Medicaid patients it’s a violation of the federal antikickback statute (the “AKS”). In fact, simply offering or soliciting remuneration for referrals is a crime under that statute.

Over the past several years, the so-called “company model” of anesthesia services has taken form, through which ASC owner surgeons have extracted a share of fees from the anesthesiologists working at the facility.

Although this post is appearing on an anesthesia blog, you may want to remind your colleagues in other specialties that the company model is not simply an anesthesiologist’s issue. In a very real sense, anesthesiologists are the “canaries in the coal mine.” Little suspension of disbelief is required to see anesthesia company model thinking permeating into other areas, say, internists setting up entities to capture the profit of referrals to gastroenterologists.

Of course, all company model situations are rife with compliance concerns.

The AKS

The AKS prohibits remuneration, that is, the transfer of anything of value, for referrals. It also prohibits offering or soliciting that remuneration.

Certain exceptions, known as safe harbors, define permissible practices not subject to the antikickback statute because they are unlikely to result in fraud or abuse. The failure to fit within a safe harbor does not mean that an arrangement violates the law; there’s just no free pass.

Joint Ventures

HHS’s Office of Inspector General (the “OIG”) coordinates enforcement of the AKS.

The OIG uses the term “joint venture” to mean any arrangement, whether contractual or involving a new legal entity, between parties in a position to refer business and those providing items or services for which Medicare or Medicaid pays. Some joint ventures are legal – others are simply disguised violations of the AKS.

The OIG issued two important alerts on joint ventures, its 1989 Special Fraud Alert on Joint Venture Arrangements, republished in 1994, and a 2003 Special Advisory Bulletin on Contractual Joint Ventures, describing the features of suspect arrangements.

In essence, suspect ventures involve an owner in one line of health care business which expands into another related health care business line to serve the owner’s federal health care program patients. The expansion is accomplished by contracting with an existing provider of the second business line – that is, a potential competitor as to the second business line. The owner essentially arranges for the existing provider to run the new business line for the new venture, with the owner participating in the profits from what are essentially its own referrals.

Safe Harbors Are Not So Safe

Both the AKS and the OIG’s regulations set forth “safe harbors,” i.e., requirements, which if complied with, provide assurance that the payment practice will not be considered a violation of the AKS.

The OIG’s position is that good faith is required for protection within a safe harbor. Additionally, as the OIG made clear in the 2003 Special Advisory Bulletin, although a safe harbor may protect the payments in one direction, the discount given in the other direction may not be protected and therefore may trigger prosecution.

The Tighter the Economy the Stickier the Fingers

As the general, and the healthcare, economies become tighter, more individuals and entities in a position to generate referrals will consider the profitability of joint ventures. A subset will disregard the issue of legality.

For years, the American Society of Anesthesiologists has been urging the OIG to adopt a Special Fraud Alert on the company model situation. The ASA’s most recent letter to the OIG on this topic, dated February 2011, sites a survey in which 41% of the responding anesthesia practices indicated that they had been approached by ASCs to do company model deals, and that out of the total 332 requests to participate in a company model entity, the practices lost their contract to provide services at the requesting ASC in at least 159 instances. The OIG has yet to act.

However, in April 2011, the OIG issued an advisory opinion (Advisory Opinion 11-03) involving a proposed pharmacy company set up very similar to the average company model deal.

In the proposed facts disclosed to the OIG, a pharmacy providing products and services to long-term care facilities would form a new long-term care pharmacy to be owned in common with one or more long-term care facilities. The long term care facilities would, of course, now share in the profits of pharmacy services generated from their own facilities.

The OIG found the proposed arrangement likely violative, focusing on similarity between the proposed deal and the problematic arrangement outlined in the 2003 Special Advisory Bulletin, with the long-term care facility owners doing nothing to operate the new venture but receiving a share of the profits. Those facility owners would have little or no business risk and the payment to the new joint venture would vary with the volume or value of referrals from the facilities to the new business.

Even though, legally, the advisory opinion does not extend beyond that particular deal, it certainly does not bode well for potential requestors of opinions in respect of anesthesia company entities. Note, though, that a deal which is planned around the problematic elements of the Fraud Alert and the Special Advisory Bulletin may well receive the approval of the OIG.

Unfortunately, there’s no bright line test and the facts and circumstances of each situation must be fully analyzed to achieve an understanding of the potential risk. But in terms of potential penalties, fines, exclusion from Medicare and Medicaid, and even jail time, understanding the risk is worth substantially more than just a good night’s sleep.

What’s your hourly rate?

I’ve long been in denial about the commoditization of anesthesiology and medicine in general.  The health care reformers have been expediting this process much to our dismay.  CNBC isn’t really helping the cause here:

It’s not uncommon for doctors to earn $100 an hour or more but one category you might not expect is anesthesiologist. These are the doctors – yes, they are MDs — who administer anesthetics, the drugs that knock a patient out, during surgery or other medical procedure.

Where do I begin with this one?  Yes they are MDs?  Why do under-informed journalists get to print this garbage?  The truth is many ACT member makes more than $100 per hour, including non-MDs.  Its only trivial until the sh-t hits the fan, the surgeon can’t remember ACLS and grandma’s rhythm doesn’t want to cooperate.  How much is that worth?  Doofus. 

Fear not because this well-researched blurb ends on a positive note for all who pass the gas:

The outlook for this profession is good, due to a growing population and growing health-care needs.

Brilliant.

Anesthesia in the NY Times

In case you missed it the NY Times ran an article about a program at Mount Sinai School of Medicine called the Humanities and Medicine Program.  The program allows select premeds admission without the usual premed requirements.  More specifically, it allows students to forego organic chemistry, physics and the MCATS.  It was designed to create more “well-rounded” physicians.  The article specifically mentions anesthesiology hence the mention in this blog:


The study found that, by some measures, the humanities students made more sensitive doctors: they were more than twice as likely to train as psychiatrists (14 percent compared with 5.6 percent of their classmates) and somewhat more likely — though less so than Dr. Kase had expected — to go into primary care fields, like pediatrics and obstetrics and gynecology (49 percent compared with 39 percent). Conversely, they avoid some fields, like surgical subspecialties and anesthesiology.


Are psychiatrists inherently more “sensitive doctors” than those of us who pass the gas?  Perhaps.  Anesthesiology done properly does involve a signficant amount of knowlege of pharm and physiology, neither of which can be understood without physics and chemsitry.  I am all for more well-rounded physicians in all fields.  The personality disorders that medicine engenders can be exhausting at times and perhaps this is one solution.   I do also agree the undergrad should be a time to study non-medical subjects as in depth as possible.   Maybe all medical schools should look into this model as the article suggests.
