Aetna Follows CMS Policy on Home Testing

Please see my earlier posts today about CMS approving home testing for OSA.

Aetna's Policy is very similar to Medicare's:

Aetna considers the diagnosis and treatment of obstructive airway disease medically necessary according to the criteria outlined below.
Diagnosis
Aetna considers any of the following diagnostic techniques medically necessary for members with symptoms suggestive of OSA:
Full-channel nocturnal polysomnography (NPSG) (Type I device) performed in a healthcare facility;
Unattended home sleep monitoring using a Type II, III, or IV device.
Split-night study NPSG in which the final portion of the NPSG is used to titrate continuous positive airway pressure (CPAP);
Note: On occasion, an additional full-night CPAP titration NPSG may be necessary if the split-night study did not allow for the abolishment of the vast majority of obstructive respiratory events or prescribed CPAP treatment does not control clinical symptoms.
Limited-channel NPSG for members with a high pretest probability of OSA (as suggested by the simultaneous presence of snoring, excessive daytime sleepiness, obesity, and observed apneas or nocturnal choking or gasping);
Video-EEG-NPSG (NPSG with video monitoring of body positions and extended EEG channels) to assist with the diagnosis of paroxysmal arousals or other sleep disruptions that are thought to be seizure related when the initial clinical evaluation and results of a standard EEG are inconclusive.
Thank you to my colleague in Ohio for sending me the link to Aetna's policy.

The Key Line in the CMS decision

Please see my post earlier today for the full CMS decision on Home Testing.

I found this line interesting:

unattended home sleep monitoring device of Type IV, measuring at least three channels

I only have a basic understanding of the main Type 4 device on the market, the Resmed ApneaLink. My understanding is that it utilizes a nasal pressure transducer. I just googled it and came up with this site:

http://www.resmed.com/en-us/products/clinical_systems/apnealink/apnealink.html?menu=products

It looks like there is an optional oximeter available, that adds 2 channels (pulse and oximetry) to the nasal pressure transducer channel, giving the required 3 channels.

Are most doctors who are currently using the Resmed ApneaLink also using the optional oximeter??? If anyone has some info about this device, please leave a comment. Thanks.

CMS Approves Home Testing for Obstructive Sleep Apnea

Decision Summary
We received a request to reconsider the 2005 National Coverage Determination (NCD) for CPAP Therapy for OSA (CAG-00093R) to allow coverage of CPAP based upon a diagnosis of OSA by home sleep testing (HST). After considering public comments and additional information, we are making the following changes to the NCD for CPAP. The revised indications and limitations NCD are noted in Appendix B.
Coverage of CPAP is initially limited to a 12 week period for beneficiaries diagnosed with OSA as subsequently described. CPAP is subsequently covered for those beneficiaries diagnosed with OSA whose OSA improved as a result of CPAP during this 12 week period.We remind the reader that Durable Medical Equipment, Prothetics, Orthotics, and Supplies (DMEPOS) suppliers are required to provide beneficiaries with necessary information and instructions on how to use Medicare-covered items safely and effectively. 42 CFR 424.57(c)(12). Failure to meet this standard may result in revocation of the DMEPOS supplier’s billing privileges. 42 CFR 424.57(d).
CPAP for adults is covered when diagnosed using a clinical evaluation and a positive:
polysomnography (PSG) performed in a sleep laboratory; or
unattended home sleep monitoring device of Type II; or
unattended home sleep monitoring device of Type III; or
unattended home sleep monitoring device of Type IV, measuring at least three channels
We remind the reader that, in general, pursuant to 42 CFR 410.32(a) diagnostic tests that are not ordered by the beneficiary’s treating physician are not considered reasonable and necessary. Pursuant to 42 CFR 410.32(b) diagnostic tests payable under the physician fee schedule that are furnished without the required level of supervision by a physician are not reasonable and necessary.
A positive test for OSA is established if either of the following criterion using the Apnea-Hypopnea Index (AHI) or Respiratory Distress Index (RDI) are met:
AHI or RDI greater than or equal to 15 events per hour, or
AHI or RDI greater than or equal to 5 and less than or equal to 14 events per hour with documented symptoms of excessive daytime sleepiness, impaired cognition, mood disorders or insomnia, or documented hypertension, ischemic heart disease, or history of stroke. The AHI is equal to the average number of episodes of apnea and hypopnea per hour. The RDI is equal to the average number of respiratory disturbances per hour.
If the AHI or RDI is calculated based on less than two hours of continuous recorded sleep, the total number of recorded events to calculate the AHI or RDI during sleep testing is at least the number of events that would have been required in a two hour period.
We are deleting the distinct requirements that an individual have moderate to severe OSA and that surgery is a likely alternative.
I wish to thank my colleague in Ohio for sending this to me.

Behavioral Sleep Medicine- Who Should Practice It?

I would like to thank Dr. Perlis for his thougtful response to my Saturday March 1 post. Since not everyone reads the comments, I think that Dr. Perlis's reply deserves its own post and am reprinting it below:

===========> Michael Perlis Reply RE: Michael Rack, MD Post #1169The Threat FROM Psychologists===========>
It is interesting that Dr. Rack phrased the subject to his email this way. I think many people who specialize in Behavioral Sleep Medicine would see this differently, i.e., be concerned about recent initiatives by the AASM as a THREAT TO the continued participation of Psychologists in Sleep Medicine.
MR: Has anyone read the editorial in this month's issue of JCSM by Michael Perlis, Phd? In this editorial about behavioral sleep medicine/CBT-insomnia, Dr. Perlis advocates for the requirement that all accredited sleep disorders centers be required to "have a provider on staff (full time or part time) who is BSM "boarded" or board eligible. ===========>

This was indeed one of many recommendations. There are two issues here. First, it is a fact that most accredited Sleep Disorders Centers (SDCs) do not have people who specialize in the assessment and tx of insomnia. Second, it is a fact that the people who are "boarded" in BSM specialize in the assessment and tx of insomnia and are the only Sleep Medicine clinicians with any certification to conduct CBT-I. So it follows that fully accredited SDCs
Given that the need to provide treatment for all sleep DXs Incl. insomnia
Given the desire to provide the highest standard of care possible
should have BSM "boarded" or board eligible on staff.

MR: I am a DABSM and also certified in sleep medicine by the ABIM. I have also passed the AASM behavioral sleep medicine certification exam, and so I periodically receive emails from Dr. Perlis regarding the issue of who can provide behavioral sleep medicine services (I am also a member of the behavioral sleep medicine committee, but I will not reveal those confidential discussions). There is a growing movement among psychologists who are upset because they are not eligible for the new physician sleep boards to require accredited sleep centers to have BSM-certified individuals (primarily psychologists) on staff.===========>
While there is a contingent of PhD clinicians that are indeed upset about not being eligible for the ABMS exam, this is not the main issue for BSM clinicians. In fact, this issue is old news. The BSM exam was designed and established by the original AASM Presidential Committee for BSM (of which I was a member) precisely to fill the void left by the closure of the ABMS to PhD clinicians. Note: Unlike the new Sleep Medicine Exam… The BSM exam is (and should continue to be) open to PhDs and MDsThe current debate is whether to extend the credentialing process to MA level clinicians (NPs, PAs, etc.). The commentary written by Dr. Smith and I airs out the issues related to this movement and how this might be achieved in a manner that guarantees the highest standards of care be maintained. Finally, please note that one of the recommendations made in our JCSM Commentary is that both BSM and ABMS certified individuals should supervise MA level clinicians.
MR: I encourage all sleep physicians to write the AASM Board of Directors and support the position that physician board certification in sleep medicine qualifies the physician to practice all aspects of sleep medicine, including behavioral sleep medicine. ===========>
There is no question that the certification in sleep medicine does indeed proffer the right for all such certified individuals to practice BSM. The real questions are
1. Do most MDs certified in sleep medicine feel themselves qualified to practice and/or supervise CBT-I and other BSM interventions ?
2. Do most MDs want to practice in this arena ? I think the answer to both questions would be an emphatic “No!”. Perhaps the best analogy, as I understand this, is that MD degree and license is sufficient to for any MD to conduct any form of medicine. So any MD, for example, can conduct assessments and treatment for sleep disorders. The question here, again, is should they ? Are they really qualified? Will they provide the best possible treatment? Like Dr. Rack – I also encourage you to engage these issues and, whatever your opinion, share them with the BSM section leaders and the AASM BOD.
MR: In addition, consider attending the Insomnia Section meeting at Sleep 2008. The Insomnia Section has become a center for psychologists who support Dr. Perlis's position.===========> Please do attend. Although if your expecting this to be a Perlis Supporter Che-Guevara-type meeting… you’ll likely be very disappointed. Sincerely Michael Perlis

Restless Legs Syndrome and Cardiovascular Disease

Dr. Poceta at Sleep Expert recently posted about the link between Restless Legs and Heart Attacks. It seems that restless legs syndrome isn't just an abnormal sensory/motor experience, it also has adverse health consequences:
In a recent blog post,
I reviewed a new study that showed an increased risk of heart disease in patients with restless legs syndrome (RLS). This study and others suggest that RLS, like sleep apnea, is more than just an unpleasant sleep disorder; such that RLS actually raises the chances of having a serious medical condition.
RLS is more than a feeling—patients with RLS have poor sleep and also have periodic limb movements (PLM's) during sleep.
PLM's are the repetitive movements of the foot, leg, and thigh that happen mostly during sleep in patients with RLS.
A recent study sheds some light on how and why RLS could lead to heart attacks—by raising blood pressure during the PLM's.
The study is published in the medical journal Clinical Neurophysiology in mid 2007.
I encourage you to read the full post at Sleep Expert, a revolutionhealth blog.

The Growing Threat from Psychologists

I recently posted the following in the American Academy of Sleep Medicine discussion forums. There is a growing movement among sleep psychologists to limit the ability of sleep physicians to practice the full aspect of sleep medicing. Specifically, some sleep psychologists are trying to make it a condition of sleep center accreditation that the sleep center has a practioner certified in behavioral sleep medicine (which is an AASM certificate examination) on staff. The AASM behavioral sleep medicine certification is primarily for psychologists, though some MD's, including myself, have taken and passed the exam.

Has anyone read the editorial in this month's issue of JCSM (The Feb issue of the Journal of Clinical Sleep Medicine) by Michael Perlis, PhD?
In this editorial about behavioral sleep medicine/CBT-insomnia, Dr. Perlis advocates for the requirement that all accreditied sleep disorders centers be required to "have a provider on staff (full time or part time) who is BSM "boarded" or board elgible.
I am a DABSM and also certified in sleep medicine by the ABIM. I have also passed the AASM behavioral sleep medicine certification exam, and so I periodically receive emails from Dr. Perlis regarding the issue of who can provide behavioral sleep medicine services (I am also a member of the behavioral sleep medicine committee, but I will not reveal those confidential discussions).
There is a growing movement among psychologists who are upset because they are not elgible for the new physician sleep boards to require accredited sleep centers to have BSM-certified individuals (primarily psychologists) on staff.
I encourage all sleep physicians to write the AASM Board of Directors and support the position that physician board certification in sleep medicine qualifies the physician to practice all aspects of sleep medicine, including behavioral sleep medicine. In addition, consider attending the Insomnia Section meeting at Sleep 2008. The Insomnia Section has become a center for psychologists who support Dr. Perlis's position.

Sleep psychologists are trying to force sleep disorders centers to hire them on staff, using AASM accreditation as the enforcement mechanism. Most sleep physicians, including myself, would have no problem with referring CBT-I (cognitive behavioral therapy for insomnia) cases out to qualified psychologists. We board-certified sleep physicians should not, however, be force to hire psychologists, nor be limited in our ability to practice the full spectrum of sleep medicine, including, if we choose, behavioral sleep medicine.

Obtaining Coverage for CPAP and CPAP titrations

Medicare and some insurance companies have strict criteria about covering the purchase of a CPAP machine for a patient. Here is my response to a question on the AASM discussion forums about getting CPAP and CPAP titrations covered for patients who have OSA/Upper airway resistance, but don't meet their insurance company's criteria for CPAP:

My understanding is that the MEdicare criteria (4% desat, etc), are for the coverage of the cpap machine. The actually cpap titration is covered if the attending feels it is medically necessary. So if the AHI (using 4% desat criteria for hypopneas) is less than 5, one approach would be to do a cpap titration-covered by Medicare- and then try to get a DME company to sell the pt a used, discounted cpap machine.

This approach also works with other insurance companies- usually diagnostic testing/titration is covered by a different department within the insurance company than DME. Though it may seem illogical, even insurance companies that have strict criteria for cpap machines will usually approve cpap titrations (at least in the state of Mississippi).

Update on Home Testing for OSA

Sleep Well and Live reports that home testing for OSA will not be covered in many states:

Effective April 1, 2008: “For a study to be reported as a polysomnogram, sleep must be recorded and staged and must be attended. Sleep studies should be performed in a hospital, sleep laboratory or by an Independent Diagnostic Testing Facility that is supervised by a physician (MD/DO) trained in analyzing and interpreting the recordings and should be attended by a trained technologist. Sleep studies performed in the home are not covered.”

The LCD affects the following primary geographic jurisdictions: American Samoa, California, Connecticut, Delaware, Guam, Hawaii, Kentucky, Illinois, Indiana, Maine, Marina Islands, Massachusetts, Michigan, Nevada New Hampshire, New Jersey, New York (with the exception of Queens County), Ohio, Vermont, Virginia, West Virginia, and Wisconsin.

The decline of physician-practice sleep labs

There are 3 basic business structures of sleep labs:
1. hospital-owned
2. independent diagnostic and testing facility (IDTF's)
3. extension of a physician practice

At the AASM Sleep Management course I went to in February, it was reported that business structure 3 comprised less than 5% of sleep labs. The differences between the 3 business structures can be complex, and I plan to talk about this more in future posts. To briefly illustrate the complexity, I will just mention at this time that physicians are often part-owners of IDTF's and hospital associated sleep labs. Physicians sometimes fully own an IDTF.

In my brief career in sleep medicine, the decline of stucture #3 has been a disturbing trend. Sleep Review Magazine reports on how a new interpretation of an old Florida law has led to severe restriction on this type of lab:

In responding to a request from Jacksonville Heart Center (Jax Heart), the State of Florida Board of Medicine finds that physicians of physician-owned labs must directly supervise sleep studies.
In its request, Jax Heart, a group practice comprised of 17 cardiovascular physicians, proposed to establish an eight-bed sleep center as part of its medical practice. The request stated, in part, “.... For sleep studies performed after normal business hours, a Jax Heart physician would be on-call and immediately available by phone."
.....the main issue with the request submitted by Jax Heart was whether the sleep center’s services were being conducted under the “direct supervision” of Jax Heart.
The State of Florida Board of Medicine stated, “If the Sleep Center does provide services under the direct supervision of Jax Heart, the Petitioner’s proposed arrangement does not constitute a ‘referral’ that is precluded by Section 458.053(5), Florida Statutes.
“We found that the law dictated that patients needing a sleep study would be supervised differently depending upon whether the lab was owned by a physician group rather than an IDTF/Hospital,” said Masters.
Ultimately, the Board found that Jax Heart would not be providing services under the “direct supervision” (meaning supervision by a physician who is present in the office suite and immediately available to provide assistance and direction throughout the time services are being performed), and that Jax Heart’s proposed referral of patients to its sleep center is precluded by Section 458.053(5), Florida Statutes.
“It is also important to note that the declaratory statement did not say that physicians are not able to own their own lab—rather that they must provide direct supervision for patient care in a sleep center,” Masters said. “Secondly, the Board reinforced that physician-owned sleep labs must only treat their patients in the sleep center. This provision would not change even if the Direct Supervision requirement was changed to be an exception.”
Read the entire decision here.
Basically, the state of Florida is requiring sleep labs that are an extension of a physician practice to have a physician present whenever sleep studies are run. This is a poorly written article; as I pointed out above, a physician can own all or part of an IDTF. There is a definite distinction between a physician-owned sleep lab and a sleep lab that is an extension of a physician practice.

My Last Comment about Home Testing for OSA

This is my last comment about home testing for OSA, until CMS makes its final decision in March. I have previously extensively discussed the AASM's task force report on home testing, and its role in bringing about home testing for obstructive sleep apnea (click on the Home Testing or Portable Home Testing label below for more details).

Nic Butkov, the RPSGT guru, discusses another development that paved the way to home testing in this month's issue of SLEEP REVIEW:
It has been suggested by some that the new scoring manual is paving the way for portable, limited channel sleep studies and automated scoring. The manual does, in fact, present the respiratory scoring parameters apart from the rest of the polysomnogram, without discussing the relevance of viewing respiratory patterns within the context of the patient's sleep/wake physiology. The only reference to other PSG channels is made by the brief mention of arousal, as a possible scoring criterion for the alternative hypopnea definition and as a criterion for the optional scoring of RERAs. The lack of discussion regarding other PSG parameters creates the impression that respiratory events can be evaluated based solely on respiratory tracings and oximetry, without viewing the polysomnogram as a whole. This is unfortunate because without correlating respiratory patterns with the patient's physiological state, and evaluating their effects upon that state, the interpretation of respiratory events becomes largely a matter of guesswork.
So in addition to the Task Force report, the new American Academy of Sleep Medicine Scoring Manual also played a role in bringing about CMS approval of home testing for qualifying a patient for cpap therapy. Although the AASM claims it is going to work with regional Mediare carriers to limit home testing to board certified sleep specialists (wouldn't it be funny if some carriers excluded diplomates of the American Board of Sleep Medicine but instead required passing the new American Board of Internal Medicine test?), it is my opinion that most Medicare carriers will not limit the specialties that can perform home testing. The AASM has made its bed and now has to lie in it.

Respiratory Therapists Try to Take over Polysomnography in California

I previously posted on the attempt of respiratory therapists to take control over polysomnography in California.
The process is moving forward. As reported by Sleep Review Magazine,
Introduced by State Sen Jeff Denham (R-Merced), the “Polysomnographic Technologist Act” Senate Bill 1125 aims to prevent criminal abuse and ensure proper medical diagnosis, as well as ensure a standard of training and accountability for the profession.
"Hundreds and possibly thousands of unlicensed technicians are working with patients in vulnerable circumstances where most have not had a criminal background check and competency testing is optional. Failure to perform competently and protect the consumer holds little or no consequence for unlicensed personnel," said Stephanie Nunez, executive officer for the Respiratory Care Board of California.
The actual text of the bill is here. Some key parts of the bill:
"Board" means the Respiratory Care Board of California.

b) The failure of an employer to provide documents as required bythis section is punishable by an administrative fine not to exceedfifteen thousand dollars ($15,000) per violation. This penalty shallbe in addition to, and not in lieu of, any other civil or criminalremedies. 3818. The board shall issue, deny, suspend, place probationaryterms upon, and revoke licenses to practice polysomnography andpolysomnography-related respiratory care services.
The board shall determine the hours of credit tobe granted for the passage of particular examinations. 3819.5. The board may require successful completion of one ormore professional courses offered by the board, the AmericanAssociation for Respiratory Care, the California Society forRespiratory Care, or the National Board for Respiratory Care in anyor all of the following circumstances: (a) As part of continuing education. (b) Prior to initial licensure.
As I interpret it, this California bill would give respiratory therapists, through their board, the power to license sleep lab technicians and fine labs that hire technicians not licensed by their board. This law is a slap in the face to the majority of sleep technicians who are not respiratory therapists.

The Failure of the AASM Leadership

The Feb 15 issue of the Journal of Clinical Sleep Medicine has an editorial on "Why CMS Approved Home Sleep Testing for CPAP Coverage", by Dr. Chediak, President of the American Academy of Sleep Medicine. The editorial is a glaring whitewash of AASM's role in this debacle. A sample statement from this editorial is: "While there was variance in the degree of conviction, in general, the AASM, ACCP, and ATS testified against the indiscriminate use of HST" (HST= home sleep testing).
Dr. Chediak makes no mention of the AASM Task Force Report on Portable Monitors in the Diagnosis of Obstructive Sleep Apnea. This report, which came out in the middle of the CMS decision making process, basically came out in favor of home testing (when performed by sleep physicians in AASM-accredited sleep centers). After the task force report came out, the perception among CMS officials and the public was that the AASM had approved of home testing. After this task report came out, how could CMS not approve of home testing?
----------------------------------------
Valid arguements can be made in favor of HST. However for the AASM to initially come out against HST and then months later publish a task force report that was widely viewed as being an endorsement of HST is an incredible lack of leadership on the part of the AASM's Board of Directors.
I think that every member of the AASM Board of Directors who voted to approve the Task Force Report should resign.

The life of a sleep doctor

I have answered 20 questions about the life of a sleep physician for the Student Doctor Network.
Here is a sample question and answer:
What is the best way to prepare for this specialty?
Sleep medicine is a one year fellowship after a psychiatry, neurology, ENT, family practice, pediatrics, or internal medicine residency. The best way to prepare is to do one or two sleep medicine elective months during residency. Sleep medicine is becoming a more competitive fellowship, and it is hard for someone who has only completed an internal medicine residency to get- general internists are competing with pulmonary specialists for slots. If a resident is trying to go straight from internal medicine residency to sleep fellowship (rather than doing a pulmonary fellowship first), some sleep research during residency would be helpful.

Treatment of Posttraumatic Sleep Disturbances

Sleep disturbance is common after head injury. Here is part of an article I wrote on posttraumatic sleep disturbance:

Patients with narcolepsy secondary to a head injury or posttraumatic hypersomnia often require stimulant medication such as methylphenidate or amphetamines in doses similar to those for idiopathic narcolepsy-cataplexy syndrome. Modafinil may be the medication of first intention; it has fewer side-effects overall than the other stimulants. The dosage is usually 300 to 400 mg, administered in 2 divided doses in the morning and at lunch time. Modafinil, however, activates hypothalamic regions and does not act directly through dopaminergic or noradrenergic pathways; and patients with severe head trauma who complain of intellectual slowness may benefit more from amphetamine-like medications. These medications will have a general “activating” effect that is not solely devoted to sleepiness. Of course, any coexistent sleep pathology or neurologic disease requires independent management. The potential beneficial effects of naps have not been studied; they should probably be restricted to less than 30 minutes to avoid significant sleep inertia effects. They should be taken when the patient feels sleepiest but not within 4 or 5 hours of habitual nocturnal sleep time.
Cases of sleep apnea resulting from a head injury are treated in the usual manner with continuous or bilevel positive airway pressure therapy. Sometimes the spontaneous/timed mode of bilevel positive airway pressure therapy is necessary for central sleep apnea and mixed obstructive/central sleep apnea. Adaptive-servo ventilation has recently become available to treat central and mixed sleep apnea, but experience in non-heart failure patients is limited. Treatment of sleep apnea should be conducted by a sleep disorders specialist. Posttraumatic organic insomnia has generally proven difficult to treat. Patients respond rather poorly to the benzodiazepine hypnotics employed to help initiate and maintain sleep. Cognitive behavioral therapy, including stimulus control, sleep restriction, cognitive restructuring, sleep hygiene education, and fatigue management, can improve nocturnal sleep quality as well as reduce daytime fatigue (Ouellet and Morin 2007

Cell Phones and Sleep

A new study suggests that mobile phones interfere with sleep:
By Geoffrey Lean, Environment Editor
Published: 20 January 2008
Radiation from mobile phones delays and reduces sleep, and causes headaches and confusion, according to a new study.
The research, sponsored by the mobile phone companies themselves, shows that using the handsets before bed causes people to take longer to reach the deeper stages of sleep and to spend less time in them, interfering with the body's ability to repair damage suffered during the day.
The scientists studied 35 men and 36 women aged between 18 and 45. Some were exposed to radiation that exactly mimicked what is received when using mobile phones; others were placed in precisely the same conditions, but given only "sham" exposure, receiving no radiation at all.
The people who had received the radiation took longer to enter the first of the deeper stages of sleep, and spent less time in the deepest one. The scientists concluded: "The study indicates that during laboratory exposure to 884 MHz wireless signals components of sleep believed to be important for recovery from daily wear and tear are adversely affected."
The embarrassed Mobile Manufacturers Forum played down the results, insisting – at apparent variance with this published conclusion – that its "results were inconclusive" and that "the researchers did not claim that exposure caused sleep disturbance".
But Professor Bengt Arnetz, who led the study, says: "We did find an effect from mobile phones from exposure scenarios that were realistic. This suggests that they have measurable effects on the brain."

My Official Comment on Home Testing

Although several posts ago I stated that I was not going to comment on home testing for osa at the official CMS comment site, I changed my mind. Here is what I posted a few minutes ago:

Comment: I am against home testing for osa, but if home testing is to be implemented, allow me to make the following suggestions:
1. DME companies should not be allowed to provide home testing, due to the conflict of interest in providing a qualifying test for a product the DME company provides.
2. Any licensed physician should be able to provide home testing for osa. I am not aware of any precedent limiting a diagnostic test to a particular specialty, and I do not believe that limiting a safe test such as portable monitoring for osa to sleep specialists is justified.
3. Related to point #2, home testing should NOT be limited to sleep labs. One of the main rationales of home testing for osa is to expand diagnosis of osa to areas/populations currently not being served by sleep labs, and limiting home testing to sleep labs would defeat this purpose.

I am against home testing for osa. With the rapidly expanding number of sleep labs, I think that most of the US is now within convenient location of a sleep lab, and I don''t see the need for a test that is inferior to in-lab polysomnography. However, now that the American Academy of Sleep Medicine has signed off on home testing, I don''t see any point in arguing further against it, and hope that you will consider my suggestions for implementing home testing.

Resmed Consultant Behind Home Testing Movement

Sleep Well and Live has an interesting post today about the movement for home osa testing and its originator:
At the 2004 Annual Meeting of the American Academy of Otolaryngology - Head and Neck Surgery Foundation in New York, Terence Davidson, an Otolaryngologist (ENT) and Dean of Continuing Education at the University of California, San Diego, was invited to give a “mini seminar” entitled “Thinking of Opening a Sleep Lab?” Dr. Davidson could also be called the “father” of the current attempt to get Medicare to approve unattended home testing for sleep apnea. It was his Jan. 29, 2004 letter to the Centers for Medicare and Medicaid Services (CMS) that argued that the current policy is inhibiting the diagnosis of obstructive sleep apnea (OSA) because the nation’s 692 sleep labs are simply too full.

During Dr. Davidson’s presentation in New York, he had some interesting opinions and comments and also seemed to have some conflicts of interest and an astounding degree of arrogance towards the Sleep Medicine and Pulmonary Medicine professions.
Although he has claimed to have no conflicts of interest, Dr. Davidson is on the Medical Advisory Board of Directors of ResMed, Inc. as a paid consultant. ResMed and their auto titration CPAP units stand to benefit substantially from gaining Medicare’s approval of in-home, unattended testing.
As to Dr. Davidson’s assertion that the current policy for our Medicare population is inhibiting the diagnosis of OSA because the nation’s sleep labs are simply too full, recent data from the American Academy of Sleep Medicine states that the availability of sleep laboratories across the United States based on a 2001 study of 2001 data estimates that 427 PSG were performed per year per 100,000 population. (5) Since 2001, the number of sleep laboratories accredited by the AASM has more than doubled to 1,169, with 129 applications having been received in just the first three months of 2007, alone.
In a 2004 AASM survey, there was an average wait of about three weeks for a sleep study or sleep consultation. An independent survey in 2004 by Shariq estimated there were more than 2,500 accredited and non-accredited sleep laboratories in the US with an average wait time for a PSG between two and three weeks.
I encourage you to read the full post.

osa home testing hits the mainstream media

This is the first news article I've seen about home testing for osa outside of an industry publication:
Last month, the American Academy of Sleep Medicine, which represents sleep centers, changed its position to say home tests can help certain high-risk patients - but should be administered by sleep specialists.Medicare's proposal wouldn't limit which doctors offer home tests. The American Academy of Otolaryngology, head-and-neck surgeons, requested the change.
There are some inaccuracies in the article, like this statement:
In fact, Medicare concluded a sleep-lab test isn't perfect, either - and thus proposed that all patients get a 12-week trial of CPAP treatment. Only if their doctors certify they're being helped would treatment continue.

Why I am not commenting (officially) on Home Testing

On the AASM discussion forum (open to members only), some have been advocating that sleep physicians comment on the CMS (Medicare) website either 1) in oppostion to home testing for osa or 2) to request that home testing be limited to certain devices or to AASM accredited sleep labs. I posted this on the AASM discussion forum a few minutes ago:

I am not going to comment on the CMS website comment section because:
1. Home testing is inevitable. How can a sleep physician argue against home testing when industry publications, such as Sleep Review Magazine, have "AASM Approves Home Sleep Testing to Detect Sleep Apnea" as one of their headlines.
2. Some have argued that sleep physicians should try to limit home testing to type 3 devices, as opposed to type 4. This would make very little economic difference to sleep centers. Frankly, if home testing is going to be a reality, I would like the freedom to pick the device that I, as a sleep professional, felt was most appropriate for the situation. For example, home oximetry could be useful for triaging patients to psg vs split-night study. Here is a study from the JCSM that supports the use of the ApneaLink, a single channel recording device: http://www.aasmnet.org/jcsm/Articles/030409.pdf
3. Some have argued that home testing should be limited to AASM-accredited labs. As an accreditation site visitor for nearly a year, it is my understanding that AASM accreditation was always meant to be voluntary, and that the AASM's position was that it did not promote accreditation status as being necessary for insurance reimbursement. The AASM is not a government agency! I don't think that the AASM should have the power to determine which sleep labs are elgible for government (Medicare) reimbursement. Michael Rack, MD
