The Globalization of Infectious Diseases

The recent arrival of Ebola in the United States has captured the attention of both the public and the media for many reasons.  One key reason is that Ebola is making many people realize for the first time that serious diseases which were formerly confined largely to developing countries have the potential to spread more widely across the globe.  But Ebola is not the first infectious disease to spread in this way, and it’s valuable for Americans to realize that many diseases which are often viewed as existing only in developing countries are already present in the developed world, due to a complex set of factors including migration and climate change.

Specifically, serious diseases transmitted by insects like chikungunya, dengue fever, and Chagas disease are already here in the United States.  I blogged here in August about DARPA’s prize to predict the spread of chikungunya, and the CDC’s estimates suggest that the disease may be finding a foothold in this country, with 11 locally-transmitted cases in addition to the more than 1500 travel-associated cases confirmed so far in 2014.  Compared to an average of just 28 cases per year since 2006, the spread is concerning.  Scientists also contend that dengue fever, a disease with similarly debilitating symptoms, is now endemic to Florida.

The case of Chagas is even more dramatic.  Categorized by the CDC as a “neglected parasitic infection,” it is estimated that 300,000 infected people live in the United States.  That’s ten times as many people as are diagnosed with ALS, a disease which has made much more of a mark on the public consciousness.  Chagas’ impact (both human and economic) on the United States’ health system is and will continue to be extremely costly, with one study estimating the economic cost to the United States at roughly $900 million annually.  Some of these costs are indirect — for instance, donated blood must now be screened for the presence of the parasite, to prevent its transmission.  But most are direct.  Over the long term, Chagas can cause severe, even fatal damage to the heart and gastrointestinal tract.  Continue reading

More on the Maine Ebola Order

By Nicolas Terry

Today’s order from Chief Judge LaVerdiere is available here. It removes restrictions on Kaci Hickox’s movements and essentially orders her to comply with the latest CDC guidelines that she was already following on a voluntary basis. According to this report the state troopers that had been posted outside her house have left. Two paragraphs at the end of the order are worth quoting in full.

First, we would not be here today unless Respondent generously, kindly and with compassion lent her skills to aid, comfort, and care for individuals stricken with a terrible disease. We need to remember as we go through this matter that we owe her and all professionals who give of themselves in this way a debt of gratitude.

Having said that, Respondent should understand that the court is fully aware of the misconceptions, misinformation, bad science and bad information being spread from shore to shore in our country with respect to Ebola. The court is fully aware that people are acting out of fear and that this fear is not entirely rational. However, whether that fear is rational or not, it is present and it is real. Respondent’s actions at this point, as a healthcare professional, need to demonstrate her full understanding of human nature and the real fear that exists.…

An interview with Ms Hickox suggested she was taking the judge’s advice, “I am sensitive… I don’t want to make anyone uncomfortable.” However, according to this recent report Governor LePage believes, “we don’t know what we don’t know about Ebola” and does not trust Ms. Hickox.

The Medical Liability Climate: The Calm Between Storms Is the Time For Reforms

By: Michelle Mello, JD, PhD
Stanford Law School and Stanford University School of Medicine

On November 4, Californians will vote on Proposition 46, a ballot initiative to adjust the $250,000 state’s noneconomic damages cap in medical malpractice cases for inflation, raising it to $1.1 million virtually overnight.  It’s a long overdue move – California has one of the most stringent damages caps in the country, and the cap really affects access to the legal system.  Now is the perfect time to do it, because after years of turbulence, the medical liability environment has calmed.

In an analysis published October 30 in the Journal of the American Medical Association (JAMA), David Studdert, Allen Kachalia and I report that data from the National Practitioner Data Bank show that the frequency and average cost of paid malpractice claims have been declining.  The rate of paid claims against physicians decreased from 18.6 to 9.9 paid claims per 1,000 physicians between 2002 and 2013, with an estimated annual average decrease of 6.3% for MDs and a 5.3% decrease for DOs. Among claims that resulted in some payment, the median amount paid increased from $133,799 in 1994 to $218,400 in 2007, an average annual increase of 5%. Since 2007 the median payment has declined, reaching $195,000 in 2013, an average annual decrease of 1.1%.

Trends in insurance premiums vary more according to which market you’re looking at, according to data from the Medical Liability Monitor’s Annual Rate Survey, but also look pretty favorable overall. None of the locations we examined showed large increases over the last 10 years, and most showed flat or declining premiums.  Continue reading

Courts as Ebola Educators

By Scott Burris

News in this afternoon is that a Maine state judge has lifted the quarantine order on nurse Kaci Hickox, saying that she “currently does not show symptoms of Ebola and is therefore not infectious.”

The ruling conforms to the best available scientific evidence and CDC recommendations.  It also shows the importance of judicial review as a check on the exercise of emergency powers. Hearkening back to the many school exclusion cases during the HIV epidemic, I hope it will help reassure a public confused by the gap between what CDC and other experts say is necessary and what some political leaders are doing.  The best way for government to keep our trust in this outbreak is to offer accurate information — and then behave accordingly.

Doctors’ Decision-Making: Regression Proof?

By Kate Greenwood
[Cross-posted at Health Reform Watch]

As I have blogged about before, last year, in Kaiser v. Pfizer, the First Circuit joined the handful of courts to have approved a causal chain of injury running from a pharmaceutical company’s fraudulent promotion, through the prescribing decisions of thousands of individual physicians, to the prescriptions for which a third-party payer paid.  To establish but-for causation in the case, Kaiser submitted an expert report and testimony from Dr. Meredith Rosenthal, a health economist at the Harvard School of Public Health. Dr. Rosenthal conducted a regression analysis to determine the portion of physicians’ prescribing of the drug Neurontin that was caused by the defendant’s fraudulent promotion, arriving at percentages ranged from 99.4% of prescriptions for bipolar disorder to 27.9% of prescriptions for migraine.

Pfizer argued that Dr. Rosenthal’s regression analysis should not have been admitted (and at least suggested that such an analysis should never be admitted in a third-party payer case) because regression analysis could not “take into account the patient-specific, idiosyncratic decisions of individual prescribing physicians.” Dr. Rosenthal’s report, the company argued, “merely demonstrated ‘correlation’ and not ‘causation.’”  The First Circuit disagreed, upholding the lower court’s determination that the challenged evidence was admissible under Federal Rule of Evidence 702, because “regression analysis is a well-recognized and scientifically valid approach to understanding statistical data” and because it “fit” the facts of the case.

Eric Alexander, a partner at Reed Smith, made a similar argument to Pfizer’s when he critiqued a decision issued in July in a third-party payer case in the Eastern District of Pennsylvania. Writing at the Drug and Device Law blog, Alexander criticized the court for failing to address “the fundamental—to us—issue of whether an economist [Dr. Rosenthal was the plaintiff’s expert in that case, too] can ever determine why prescriptions were written.”  Alexander points out that “[t]o get to millions of dollars of revenue from prescriptions, many physicians have to prescribe the drug to many patients[,]” and those physicians can “pretty much do what they want[.]” Economists, Alexander argues, should not be allowed to by-pass this complexity and simply “assume” causation.

I would argue that, as idiosyncratic as physician decision-making may be, it is not uniquely so.  Continue reading

Above the (Public Health) Law: Healthcare Worker Deception and Disobedience in a Time of Distrust

[Author’s Note: Addendum and updates (latest: 4  pm, 10/31) added below.]

A physician shall… be honest in all professional interactions, and strive to report physicians… engaging in fraud or deception, to appropriate entities.
AMA Principles of Medical Ethics

This is a troubling series of news reports about deception and defiance on the part of some healthcare workers (HCWs) in response to what they believe to be unscientific, unfair, and/or unconstitutional public health measures (to be clear, the text is not mine (until after the jump); it’s cut and pasted, in relevant part, from the linked sources):

(1) Ebola Aide Doc: I’m Not Telling My Team To Tell The Truth

Gavin Macgregor-Skinner, an epidemiologist and Global Projects Manager for the Elizabeth R. Griffin Foundation, who has led teams of doctors to treat Ebola in West Africa, reported that he “can’t tell them [his doctors] to tell the truth [to U.S. officials]” on Monday’s “CNN Newsroom.”

“At the moment these people are so valuable . . . I have to ensure they come back here, they get the rest needed. I can’t tell them to tell the truth at the moment because we’re seeing so much irrational behavior,” he stated. “I’ve come back numerous times between the U.S. and West Africa. If I come back now and say ‘I’ve been in contact with Ebola patients,’ I’m going to be locked in my house for 21 days,” Macgregor-Skinner said as his reason for not being truthful with officials, he added, “when I’m back here in the US, I am visiting US hospitals everyday helping them get prepared for Ebola. You take me out for three weeks, who’s going to replace me and help now US hospitals get ready? Those gaps can’t be filled.

He argued that teams of doctors and nurses could be trusted with the responsibility of monitoring themselves, stating, “When I bring my team back we are talking each day on video conferencing, FaceTime, Skype, text messaging, supporting each other. As soon as I feel sick I’m going to stay at home and call for help, but I’m not going to go to a Redskins game here in Washington D.C. That’s irresponsible, but I need to get back to these hospitals and help them be prepared.

UPDATE: Here is the CNN video of his remarks.

(2) Ebola Doctor ‘Lied’ About NYC Travels

The city’s first Ebola patient initially lied to authorities about his travels around the city following his return from treating disease victims in Africa, law-enforcement sources said. Dr. Craig Spencer at first told officials that he isolated himself in his Harlem apartment — and didn’t admit he rode the subways, dined out and went bowling until cops looked at his MetroCard the sources said. “He told the authorities that he self-quarantined. Detectives then reviewed his credit-card statement and MetroCard and found that he went over here, over there, up and down and all around,” a source said. Spencer finally ’fessed up when a cop “got on the phone and had to relay questions to him through the Health Department,” a source said. Officials then retraced Spencer’s steps, which included dining at The Meatball Shop in Greenwich Village and bowling at The Gutter in Brooklyn.

Update 11PM, 10/30: A spokesperson for the NYC healh department has now disputed the above story, which cites anonymous police officer sources, in a statement provided to CNBC. The spokesperson said: “Dr. Spencer cooperated fully with the Health Department to establish a timeline of his movements in the days following his return to New York from Guinea, providing his MetroCard, credit cards and cellphone.” . . . When CNBC asked again if Spencer had at first lied to authorities or otherwise mislead them about his movements in the city, Lewin replied: “Please refer to the statement I just sent. As this states, Dr. Spencer cooperated fully with the Health Department.”

(3) Ebola nurse in Maine rejects home quarantine rules [the WaPo headline better captures the gist: After fight with Chris Christie, nurse Kaci Hickox will defy Ebola quarantine in Maine]

Kaci Hickox, the Ebola nurse who was forcibly held in an isolation tent in New Jersey for three days, says she will not obey instructions to remain at home in Maine for 21 days. “I don’t plan on sticking to the guidelines,” Hickox tells TODAY’s Matt Lauer. “I am not going to sit around and be bullied by politicians and forced to stay in my home when I am not a risk to the American public.”

Maine health officials have said they expect her to agree to be quarantined at her home for a 21-day period. The Bangor Daily News reports. But Hickox, who agreed to stay home for two days, tells TODAY she will pursue legal action if Maine forces her into continued isolation. “If the restrictions placed on me by the state of Maine are not lifted by Thursday morning, I will go to court to fight for my freedom,” she says.

Some thoughts on these reports, after the jump.  Continue reading

Asian Americans as a Vulnerable Population

By Deborah Cho

I was excited to learn of an article in a recent issue of American Family Physician on the topic of caring for Asian American patients.  The contents of the article are worth a read (most of it is available here), but it generally states that medical providers should consider the Asian American health care culture in their care of Asian American patients.  That information is not new, but it does highlight important facets of the Asian American culture, such as the collectivistic approach within families to medical decisions and that many Asian American patients do not mention the use of supplements and herbals unless explicitly asked during medication review.  Though these tips were worth mentioning, the main reason this article caught my attention was because it was about a population that often seems overlooked in health care.

I think one reason that there appears to be little attention on the nuances of caring for Asian American patients is buried in this phrase: “despite the common perception that all Asians are well-educated, many Asian immigrants have low educational attainment and poor medical knowledge.” (emphasis added).  Perhaps we do not consider this population to be vulnerable or otherwise in need of particular concern.  As the author of the AFP article notes, however, this perception is possibly misguided (“30% of Vietnamese Americans 25 years or older have completed less than a high school education (compared with 11% in non-Hispanic whites)” and “A high percentage of Asian Americans have limited English proficiency”).  Continue reading

HLS Health Law Workshop with Matt Lamkin

HLS Health Law Workshop: Matt Lamkin

November 3, 2014 5:00 PM
Griswold Hall, Room 110 (Harvard Law School)
1525 Massachusetts Ave., Cambridge, MA [Map here.]

Download the paper: “Regulating Identity: Medical Regulation as Social Control”

Matt Lamkin is Assistant Professor of Law at the University of Tulsa College of Law. He previously was a Fellow at Stanford Law School’s Center for Law and the Biosciences. Prior to entering academia, he was in private practice in Chicago and Indianapolis, served as a law clerk to a federal judge, and worked as a policy advisor to the Mayor of Indianapolis. Matt’s scholarship explores the intersection of health care, law, and ethics, with a particular focus on how the increasing commercialization of medical care is reshaping our understandings of disease and disability, informed consent and personal responsibility, and the role of government in regulating medical care.

Against Hearings in Medicare?

As the backlog of Medicare appeals indicates, Medicare claimants are seeking many more hearings than we can currently provide. The mismatch makes a fundamental question particularly acute: Why do we hold hearings to review Medicare coverage decisions in the first place?

It’s a question worth asking. The Affordable Care Act mandated that denials of private health insurance coverage be reviewed by external, contract medical specialists, without a hearing. (See here.) If we are comfortable with private, sometimes profit-motivated coverage decisions obtaining external review review by someone other than an Administrative Law Judge (ALJ), without a hearing, why do we feel differently about Medicare coverage decisions?

Ebola: A Problem of Poverty Rather than Health

By David Orentlicher
[Cross-posted at Health Law Profs and PrawfsBlawg.]

Undoubtedly, the death toll in West Africa would be much lower if Guinea, Liberia, and Sierra Leone had better health care systems or if an Ebola vaccine had been developed already. But as Fran Quigley has observed, Ebola is much more a problem of poverty than of health. Ebola has caused so much devastation because it emerged in countries ravaged by civil wars that disrupted economies and ecosystems.

Ultimately, this Ebola epidemic will be contained, and a vaccination will be developed to limit future outbreaks. But there are other lethal viruses in Africa, and more will emerge in the coming years. If we want to protect ourselves against the threat of deadly disease, we need to ensure that the international community builds functioning economies in the countries that lack them.

Our humanitarian impulses in the past have not been strong enough to provide for the needs of the impoverished across the globe. Perhaps now that our self-interest is at stake, we will do more to meet the challenge.

Problems with Medicare’s Settlement Methods

One option for dealing with the backlog of Medicare claims waiting for a hearing is to settle them. That’s up to the Centers for Medicare and Medicaid Services, not the Office of Medicare Hearings and Appeals that actually oversees the process, so it’s not an administrative fix that the Office of Medicare Hearings and Appeals could actually implement alone. But it is worth considering, and the CMS has shown an openness to it by going along with the proposal for facilitated settlement and by offering to settle a big chunk of pending inpatient hospital admission disputes for 68 cents on the dollar. (See Nick Bagley’s post at the incidental economist.)

These settlement efforts have received some high-level scrutiny, however. Last month Representative Brady, Chair of the House Ways and Means Committee, Subcommittee on Health, sent the HHS a strongly-worded letter after the inpatient hospital settlement was announced, arguing that the settlement may exceed CMS’s statutory authority, among other problems. (See the letter linked here (“I question whether HHS has statutory authority for this settlement process.”)

I tend to share Congressman Brady’s skepticism.  Continue reading

Ebola Quarantines: Remembering Less Restrictive Alternatives

By Wendy Parmet

The heartfelt letter issued by Kaci Hickox, the nurse being held in quarantine in a New Jersey hospital, calls into question the surprising decision by Governors Christie and Cuomo to quarantine health care workers returning from West Africa. It also shines a spotlight on the all-important, but largely unexplored, question of how the less restrictive “alternative test” applies to quarantine. In her letter, Hickox describes being treated in a shockingly harsh and unsupported manner, being kept for hours in isolation at Newark International Airport, and then in a tent outside of University Hospital in Newark, given only a granola bar to eat. Even after she tested negative for Ebola, and her purported fever had vanished, she remains confined in the hospital. How, she asks, will returning health care workers be treated when they return from Africa?  “Will they be made to feel like criminals and prisoners?”

Hickox’s question points to the critical flaw in the decision by Governor’s Cuomo and Christie to quarantine asymptomatic health care workers returning from Africa. By using the “big gun” of quarantine, the most restrictive public health law we have, rather than a less restrictive approach, the Governors seek to show an anxious public that they’re being tough on Ebola. No doubt this is a politically popular stance. But, as many public health experts have noted, the Governors’ approach can only impede efforts to convince health care workers to go to Africa, where they are desperately needed if the world is to be freed of Ebola. The quarantines may also discourage US-based health care workers and first responders from caring for those who are stricken stateside. If 21 days of confinement in a hospital is demanded for those who care for patients in Liberia, why won’t the same approach be used here? And if so, who will answer the 911 call?

The dangers posed by the Governors’ draconian approach demonstrate the public health importance of the basic constitutional principles that guide the law of quarantine: while governments have the right, if not the duty, to impose quarantine in appropriate circumstances to protect the public’s health, individuals can only be detained when doing is the least restrictive alternative. Exactly what that means has not been fully explored by the courts, in part because quarantine cases are relatively rare. Most modern cases concern patients with tuberculosis. These cases, including ones from New York and New Jersey (e.g., City of New York v. Doe, 205 A.D.2d 469, 614 N.Y.S.2d 8 (N.Y. App. Div., 1 Dept. 1994); City of Newark v. J.S., 652 A.2d 265 (N.J. Super. Ct. Law Div. 1993)), suggest that detention is permissible, but only upon a showing that the patient has been non-complaint with less restrictive approaches (such as directly observed therapy). Courts have also made clear that prisons are not appropriate placements for patients, and that decisions must be based on the best medical and public health evidence. And although courts have not explored these issues, it seems clear that states must provide care and support for those are unable to care for themselves due to public health orders. People who are quarantined are serving the public. We need to treat them accordingly.

In the face of Ebola, fealty to the least restrictive means principle as well as sound public health policy requires that policymakers proceed with a far more nuanced approach than we have seen from the Governors of New York and New Jersey. Without question, public health controls are appropriate, indeed necessary, in response to this awful disease. In Dallas, health officials required health care workers to sign documents agreeing to self-monitor and avoid public transportation. Because Ebola cannot be spread before someone becomes ill, even the latter may be excessive. But these measures were far less restrictive and more tailored than those now being employed in New Jersey and New York. Indeed, a wide range of measures lie between the neglect the public fears, and the over-reaction that the Governors have instituted. Both public health and the Constitution demand we explore them.

Ebola and Privacy

By Michele Goodwin

As the nation braces for possibly more Ebola cases, civil liberties should be considered, including patient privacy.  As news media feature headline-grabbing stories about quarantines,  let’s think about the laws governing privacy in healthcare. Despite federal laws enacted to protect patient privacy, the Ebola scare brings the vulnerability of individuals and the regulations intended to help them into sharp relief.

In 1996, Congress enacted the Health Insurance Portability and Accountability Act (HIPAA) to protect patient privacy.  Specifically, HIPAA’s Privacy Rule requires that healthcare providers and their business associates restrict access to patients’ health care information.  For many years, the law has been regarded as the strongest federal statement regarding patient privacy. But it may be tested in the wake of the Ebola scare with patients’ names, photographs, and even family information entering the public sphere.

Ebola hysteria raises questions not only about how to contain the disease, but also to what extent Americans value their healthcare privacy.  What liberties are Americans willing to sacrifice to calm their fears?  How to balance the concern for public welfare with legal and ethical privacy principles?  For example, will Americans tolerate profiling travelers based on their race or national origin as precautionary measures?  What type of reporting norms should govern Ebola cases?  Should reporting the existence of an Ebola case also include disclosing the name of the patient?  I don’t think so, but the jury appears out for many.

Art Caplan on Ebola Quarantines

Over at his NBC News column, Art Caplan proposes a different approach to quarantining ebola “heroes.”

How to combat fear? Honor these heroes by giving them paid R &R, with their partner if they so choose, for 21 days. Give them a vacation in the guise of quarantine. Give them a reason to want to go back to fight Ebola. Give other doctors and nurses a reason to emulate them. Build or buy a nice hotel for these heroes.

And more, on why a general quarantine is a bad idea:

When officials respond to panic with quarantine they basically say they can’t trust public health officials, science and the ethics of doctors and nurses. There is no substitute for that trust. None. If state and city officials undermine trust out of panic or politics, then they destroy the best weapon we have to control Ebola — good science implemented by heroes.

The Ebola “Czar”

By David Orentlicher
[Cross-posted at Health Law Profs and PrawfsBlawg.]

In the wake of Craig Spencer’s decision to go bowling in Brooklyn, governors of three major states—Illinois, New Jersey, and New York—have imposed new Ebola quarantine rules that are inconsistent with national public health policy, are not likely to protect Americans from Ebola, and may compromise the response to Ebola in Africa, as health care providers may find it too burdensome to volunteer where they are needed overseas. Don’t we have an Ebola czar who is supposed to ensure that our country has a coherent and coordinated response to the threat from Ebola?

Of course, the term “czar” was poorly chosen precisely because Ron Klain does not have the powers of a czar. He will oversee the federal response to Ebola, but he cannot control the Ebola policies of each state. Unfortunately, on an issue that demands a clear national policy that reflects medical understanding, public anxieties will give us something much less desirable.
