The Future of Health Reform - IV - Patients

From a coverage standpoint, patients (in select states) have been the big winner of the PPACA. Let's look at how.

First, and most importantly, the PPACA has delivered on its promise to get more people covered through health insurance.

This graph from Obamacarefacts (a pro-Obamacare website) shows the percentage of uninsured in the US by quarter from 2008 to 2015. The uninsured rate dropped from an average of ~16% before the PPACA went fully into action to ~11% with the insurance provisions in full effect.

The graph below shows the uninsured rate on a longer timescale, going back to 1963 when Medicare and Medicaid were introduced. Medicare and Medicaid brought the uninsured rate from 25% to ~15%, which has of course dropped down to 11% after PPACA.

Now, over the course of a middle class person's life, his insurance coverage will be as follows:


  • As a student and up until age 26, he will be covered under his parent's insurance
  • In his working years, he will be covered through insurance provided through work. If he is in a small company (less that 50 full-time employees), he will get insurance through an exchange.
  • In his retirement years, he will receive Medicare after age 65. 
For a lower class person who has trouble gaining and keeping employment, he will be covered by Medicaid. Medicaid has expanded eligibility going up to 133% of the Federal Poverty Line.

According to a Forbes article, the newly insured come from various sources:

  • 9.6 million from employer sponsored plans (42%)
  • 6.5 million from an expansion in Medicaid  (28%)
  • 4.1 million from individual plans on state exchanges (18%)
  • 1.2 million from individual plans not on state exchanges (5%)
  • 1.5 million from other insurance sources (7%)

The article suggests that the gains in the employer sponsored plans could simply be due to a recovering economy. In addition, the articles suggests that the individual mandate is haven't the desired effect.

With the state exchanges making health care insurance more affordable, the expansion of Medicaid eligibility, combined with the penalties imposed on businesses and individuals for not having insurance, I wonder why the insured rate hasn't dropped down further than 11%. I would expect that only those people who pay the penalty for not having insurance would not be covered. Let's examine the uninsured population in an Obamacare world.

According to a Kaiser Family Foundation article, the main reasons for lack of insurance are:


  • High cost of insurance
  • No job and therefore no insurance through work
  • Poor adults in states that didn't expand Medicaid
  • People who didn't know about the subsidies available to them 
  • Undocumented immigrants aren't eligible for insurance

In a later article, we'll discuss the implementation of Obamacare, in particular which states expanded Medicaid and which set up their own health care exchanges.

The Future of Health Care Reform - III - Jobs

In my last article in the series, I wrote that PPACA is now expected to have a negative impact on the federal budget due to reduction in labor, and thus the reduction in taxes to the government. Let's dive deeper into how the PPACA will affect the labor market. There are two sides to this issue: Obamacare opponents make a more direct argument on the reduction of jobs and cutting of hours, while Obamacare proponents argue that the law will indirectly improve the labor market.

Negative Impact to Labor Market

Obamacare requires businesses with more than 50 full-time employees to subsidize health insurance for their employees. Full-time employees are defined as those who work more than 30 hours per week. 

Subsidizing health care for employees is large expense for companies. Companies on average pay:

  • $5,179 for single employees (83% of the premium)
  • $12,591 for employees with families (72% of the premium)



As a result of the law, in order to bring their costs down, many companies have resorted to tactics like:
  • Not hiring employees to get under the 50 employee limit
  • Cutting hours to less than 30 so as to have fewer full-time employees to provide insurance for
  • Cutting other benefits
  • Raising prices of their products
  • Cutting back on raises
Small Business Health Care Survey
Companies that can't offset the costs of providing health insurance have to deal with lower profits and lower stock prices. These companies pay fewer taxes to the government, leading to the budget deficit we saw in the previous article.

Forbes - Obamacare Killing Jobs

Positive Impact to Labor Market



According to Obamacarefacts, a pro Obamacare website, PPACA "creating new jobs in healthcare and government, increasing operating costs for some larger businesses, eliminating 'job-lock', and saving money for small businesses via the SHOP marketplace."


The website also cites that there have been 58 months of consecutive job growth, so allegations of 'job killing' are exaggerated. 
In addition, PPACA allows for "tax credits for up to 50% of employee premiums to smaller firms with less than 25 full-time equivalents, so they are be able to attract more workers due to their ability to provide them with better benefits at cheaper rates."

The main argument from the pro-Obamacare side is that employees no longer need to stay at jobs they don't like simply to get insurance. Because of the insurance exchanges, they can change jobs to one they like more and still get insurance. Thus, PPACA increases job mobility, which ultimately spurs the economy.

Finally, the strongest argument for Obamacare's positive impact on the economy is the same one that progressives use to justify most of their government spending initiatives: if people are healthier, they will be happier, more productive members of society. In economic terms, they will work harder and generate more revenues for their businesses, thus spurring the overall economy. This is a strong argument, even if it is highly indirect.

Obamacare Facts

Summary

Both sides of the argument have their merits. The negative argument makes a more direct connection between the law's effects and the impact to companies. In addition, we have been in a bull market for the last few years. So, we can't give PPACA the credit for the job growth or say that it hasn't hurt jobs as the effects may have been masked by general economic growth.

The real test of Obamacare and the job market would come if the economy falters. What will employers do then?

Until then, I believe the negative side has the stronger arguments and assert that the direct effects of PPACA aren't good for the economy. 

Eli Lilly's Alzheimmer Drug Fails in Pivotal Trial

Taking a break from PPACA analysis, I'm going to examine an Alzheimmer's drug that failed its pivotal trial last week. That drug is solanezumab from Eli Lilly. Upon announcement of the failed trial, Eli Lilly's stock dropped 11%.

Solanezumab is a monoclonal antibody which aims to prevent or reduce amyloid plaque in the braid. Amyloid plaque is thought to be a cause or effect of Alzheimmer's disease. The drug attaches to free amyloid protein to prevent it from joining together with other protein to form plaque.

I didn't follow this drug carefully, but it appears that it had failed two previous trials, so expectations may have already been tempered and priced into the stock. Those two trials suggested that Solanezumab may have a positive effect in patients with mild dementia. These results were the design of Eli Lilly's Phase III trial for solanezumab.

Unfortunately, patients treated with the drug did not experience a statistically significant decrease in cognitive impairment, the primary endpoint for the clinical trial.

But, even in this failure there are important learnings for alzheimmer's treatment. The clinical experience of Solanezumab suggests that by the time amyloid shows up on brain scans, it may be too late for amyloid plaque reduction to improve a patient's cognitive abilities. Thus, the effects of the disease and the resulting dementia may have set in much earlier.

If that's true, then Alzheimmer's research could go into two directions:

1) Earlier detection. If the plaque is found in its very early stages and removed, can dementia be avoided? --> Can we use liquid biopsy and genomic testing to identify early stage Alzheimmer's disease?

2) Regeneration of brain cells involved in cognitive abilities. The amyloid plaque may just be an effect of Alzheimmer's disease. --> Can we use stem cell therapy to regenerate the appropriate places in the brain?

Of course, a variety of other approaches are being studied:

  • Gantenerumab (Roche): amyloid plaque reducer for people who haven't shown symptoms yet
  • BACE inhibitors: block an enzyme required for amyloid plaque production
  • Crenezumab (Genentech): passive immunity monoclonal antibodies for alpha beta peptides

The Future of Health Care Reform - II - PPACA Budget

The PPACA was expected to increase federal spending by $2T. However, it was also expected to reduce the budget deficit through revenues to the government. Now, that appears not to be true. 

First, looking at the provisions of PPACA, we can identify the ones that expand government. These are the ones that must be paid for. These are: 

Government Spending
  • Expanded Medicaid eligibility to 133% of Federal Poverty Line
  • Simplified enrollment in CHIP (Children's Health Insurance Program)
  • Setting up government run health care exchanges to allow people not covered through other means to purchase health care. 
  • Tax credits for individuals and families who make less than 400% of the Federal Poverty Level who buy their health care through a state exchange.
  • Cost sharing subsidies for individuals and families who make less than 400% of the Federal Poverty Level who buy their health care on an exchange. 
  • High risk insurance pool of $5B as a stop gap measure to insure individuals with pre-existing conditions until PPACA takes full effect.
The PPACA has one way in which it reduces government spending:

Government Spending Cuts

  • Medicare payments to providers would be bundled and would be reduced
Finally, the PPACA creates multiple sources of revenue to support the increase in government spending:

Revenue to the Government

  • .9% increase in Medicare tax rate and 3.8% new tax on unearned income for people making more than $200,000 / year (as individuals) or $250,000 / year (as joint filers) --> $210B
  • Annual fee on health insurance providers --> $60B
  • 40% tax on "cadillac" insurance policies that cost more than $10,200 for an individual and $27,500 for a family --> $32B
  • Fee on manufacturers and importers of branded drugs --> $27B
  • Medical device tax of 2.3% --> $20B
  • When filing taxes, medical expenses can only be deducted if they exceed 10% of an individual's adjusted gross income (up 2.5% from 7.5% prior to PPACA) --> $15B
  • Limit of $2,500 to Flexible Spending Accounts, which are deducted from income subject to payroll tax --> $13B
  • Other sources (i.e 10% tax on individuals who utilize tanning salons) --> $14B
Impact to Federal Budget

The PPACA was not intended to raise the federal deficit. However, estimates have changed over the years on its impact to the deficit. Initially, based on a 2012 estimate from the Congressional Budget Office, PPACA was expected to reduce the deficit by $109B from 2013-2022, and $180B from 2015-2024. 

However, Senate Budget Committee (SBC) estimates from 2014 show that PPACA will increase the federal deficit by $131B, largely due to reduced revenue to the government from reduced labor. In other words, the SBC believes that by 2024 the PPACA will result in 2.5M workers leaving the work force, a reduction in hours by 1.5 - 2%, and a reduction in wages of 1%. This reduction in labor will reduce the amount of taxes (including Medicare taxes) paid to the government. 

Of course, the budget impact is highly sensitive to the impact on the job market, as that creates the tax base for the government. If labor force participation increases, so too will the taxes paid to the government, and PPACA will again show a surplus. 

The next article will examine the impact of the PPACA to the jobs market.

The Future of Health Care Reform - I - Obamacare Defined

Now that the dust of the 2016 election has settled, we can expect the health care landscape to change, probably dramatically. In the first part of this series, I'll cover the main components of the Patient Protection and Affordable Care Act (PPACA):

1. Expansion of coverage to more citizens

2. Increasing the quality of that coverage

3. Increasing the quality and reducing the cost of care


I. Expansion of Insurance Coverage

A. Insurance companies can't deny coverage based on pre-existing conditions

B. Expanded Medicaid eligibility to 133% of Federal Poverty Line

C. Simplified enrollment in CHIP (Children's Health Insurance Program)

D. Children could remain on parent's insurance until age 26

E. Individual Mandate - all citizens must have health insurance

E1. Government run health care exchanges were setup to allow people not covered through other means to purchase health care.


F. Employer Mandate - businesses with over 50 employees must offer health insurance or pay a fine

II. Increasing Quality of Insurance Coverage

A. Essential Health Benefits - all health insurance must provide essential health benefits to its covered members. https://en.wikipedia.org/wiki/Essential_health_benefits

B. Contraceptives & Women's Reproductive Health must be covered

C. Risk management for insurance companies - temporary reinsurance, temporary risk corridors and permanent risk adjustment.

D. Elimination of lifetime coverage caps on essential health benefits

E. Can't drop policy holders when they get sick

F. Out of pocket expenses must be capped

G. Same premium to members based on age, not gender or pre-existing conditions

H. Preventive care, vaccinations and medical screenings cannot be subject to co-payments, co-insurance or deductibles.

I. 4 tiers of insurance coverage: bronze, silver, gold, and platinum.

J. 80-85% of premium costs must go to health care coverage. Rebates must be issue if this is violated.

III. Increasing the Quality and Reducing the Cost of Care

A. Creation of ACOs (Accountable Care Organizations). ACOs are groups of health care providers that come together to provide high quality, cost effective care to Medicare patients. If successful, the ACO will share in the savings it has generated.

The PPACA is one of the most complex and sweeping pieces of legislation that has been passed by the US government. In the next series, we'll cover how this legislation is being funded.

Hearing Glasses

Medical technology is rapidly improving to restore compromised senses. Our sensory abilities depend on our body’s ability to 1) obtain environmental signals 2) process those signals and 3) respond based on those signals. My time working on spinal cord stimulators has given me an appreciation of these processes and the problems that can arise. The acquisition of external signals comes from our key sensory organs: ears (hearing), eyes (seeing), nose (smelling), skin (touching), and mouth (tasting). The signals are transmitted to the brain via the spinal cord. In the brain, the signals are processed and we make decisions on what to do next based on the analysis: if the cookie tastes good, we have another bite. If the stove is hot, we retract our hands. If the song is good, we turn the radio up. Because we need our senses to interact with the world, not surprisingly, when our senses are compromised, quality of life is dramatically compromised. 
























As neurostimulation has advanced, our ability to restore the senses has improved. However, this technology is usually incredibly difficult to get right, invasive, expensive, and fraught with regulatory hurdles. Spinal cord stimulators, for example, though highly effective for some types of pain, can cost  upwards of $25,000. Thus, solutions that can improve external acquisition of signals could be attractive on many levels. 

My dad has trouble hearing and has worn hearing aids for the last several years. While hearing aid technology has improved, there are fundamental issues that still exist. He can hear pretty well in a 1:1 conversation, provided the person he is speaking to doesn’t have soft voice. However, he struggles listening to someone who is talking to him in a crowded room. Apparently, this is a common problem for people with moderate to severe hearing loss: 


According to this article, one of the causes of hearing problems in crowded rooms is the inability to hear a normal range of frequencies. 

One solution to this problem is a product out of Holland: the Varibel Hearing Glass.  
According to Varibel, with regular hearing aids, people “hear each noise, amplified, creating an uncomfortable experience for the wearer”. By contrast, Variable’s Hearing Glasses amplify sound coming from the front while dampening. The user will theoretically be able to better hear the person he is talking to while not getting distracted by background noise. 

Varibel offers two varieties. The first offers bluetooth connectivity to a smartphone. The second offers four microphones for directional hearing. It costs 2,300 - 2,500 Euros. 

Unlike neurostimulation approaches, this approach to hearing problems is non-invasive (no surgery required), and focuses on improving signal acquisition. 

The company has been around since 2003 but does not sell in the US. As a medical device professional, I’m surprised I haven’t heard of this technology. Why might that be? With products of this nature (they should be home runs, but aren't), I have found that the problems usually boil down to:

  • The product doesn’t work 
  • The product is uncomfortable
  • The product is too expensive
    • Insurance doesn’t reimburse it
  • The product looks tacky
We can look to Google Glass's short time on the market to get clues on what might be slowing up Varibel.

Google Glass was halted (at least temporarily) due to technical issues (some described it as a product not ready for primetime), but also in large part to the negative social perception. However, I expect that a product like Varibel’s would not create the same negative backlash as it is aimed to improve the quality of life of its users, and no one is going to object to that. 

I look forward to the day when a product with Google Glass-like features is launched with improved aesthetics and augmented hearing features. Clinical trials may ultimately be needed to establish efficacy and to ensure reimbursement by insurance providers.  Else, the price may need to be lowered drastically to ensure that the majority of the market can afford the product through out-of-pocket payment. People certainly need cheaper, non-invasive solutions like this to their hearing problems.

Medical Sorcery

Modern healthcare is akin to "witchcraft", according to Vinod Khosla, co-founder of Sun Microsystems and former Kleiner Perkins venture capitalist who recently started his own VC firm (Khosla Ventures). According to Khosla, in Do We Need Doctors or Algorithms, technology will replace 80% of physicians. Machines, which can assimilate large sets of data, can do much of the work of physicians, he argues. Khosla also believes that major disruptions in the health care industry will come from individuals outside the industry. He cites the example of Square, a revolutionary wireless payment system that allows anyone to accept credit cards. How did Square do to the payments industry what many had tried and failed to do? According to Khosla, the background of Square employees made this disruption possible: only 5% of Square's 250 employees worked in the industry.

In the last 3 years, I have worked with dermatologists, oncologists, interventional cardiologists, pain anesthesiologists, and neurosurgeons. I wonder how the roles of these physicians have changed over time, and how they will change in an era where technology plays a larger role in 1) determining therapies and 2) the therapy itself.

As expected, Khsola's 2011 comments drew wide spread discussion and criticism from the medical community.  Many felt that a doctor's intuition and therapuetic touch can not be replaced. In addition, decision support software is less likely to impact the work of surgeons and other procedure-oriented physicians. The work of surgeons has already been aided by the robotic surgery industry (i.e. Intuitive Surgical's Da Vinci robot), but it's unlikely that robots will ever be able to completely replace surgeons (at least not in the next 50 years).

Khosla is not saying anything new. Health care is already becoming more data-driven, and his comments are designed to put more focus into this area. Certain biotech drugs (like Genentech's Herceptin) are based on genetic tests to determine what type of cancer a patient has. In this case, Herceptin is prescribed for patients with Her II+ breast cancer. This type of product would probably satisfy Khosla's desire for "data-driven medicine". Herceptin is just one of many examples of drugs prescribed based on genetic testst.

While I'm confident that we can develop the algorithms to help physicians make the right diagnosis and prescribe the right treatment, the challenge will be gathering the inputs to the algorithm. The inputs will come from potentially numerous tests that patients must endure to ensure adequate information for the treatment algorithm. If some of the data is missing, the output of the algorithm will be less trustworthy and the physician will likely "go with his gut" for the diagnosis and treatment (defeating the purose of the decision support algorithm). So, the question becomes how can we make it easier / cheaper to perform these tests on the patient.  Once the data is acquired, it needs to be stored in a central location which the doctor can access to decide what to do next. The data can even be transmitted back to an implanted devices that change their treatment process based on this information (closed loop feedback).

Khosla's firm has invested in several diagnostic company focused on making data capture easier. For example, AliveCor sells a portable heart monitor that can be snapped onto your iPhone. This monitor records ECGs (Electrocardiograms) and transmits them to your doctor. Currently, AliveCor's product does not provide a diagnosis. However, in time, the device could do this as well. If it does, a significant portion of cardiologists' value would be eliminated. If it does, reimbursement for cardiologist office vists would need to be reduced drastically. In fact, there may be fewer visits to the cardiologist period. Mid-level practioners (who don't diagnosis but who are involved with the therapy) may see an increase in business or expanded roles. Even now, AliveCor's product is bad news for medical device manufacturers of in-office ECGs and for physicians who can bill for performing the ECG.

Making health care more data driven will empower patients as well. As a medical device marketing professional, I'm amazed at how little some patients know about what is happening to them and what is being implanted in them. The advice of the physician is often trusted blindly. Unfortunately, physicians themselves are not always well-educated on therapies, and may make their decisions based on a relationship with a particular manufacturer more than what is best for the patient. Patients, on the other hand, have no other incentive than to choose the therapy that makes them feel better. If patients are given more information on their condition, they may also be more motivated to follow through on the therapy as they get more quantitative feedback on key metrics.

Khosla is right. We should strive for data-driven health care diagnoses and treatments. However, just as auto mechanics have a variety of tests that can be run on cars to diagnosis the problem, the conclusions of the tests are not a substitute for hearing from the mechanic himself. And, for problems with the human body, human interaction is even more craved. Still, when more data is available, patients can play a greater role in their own health.
