Houston may be home to the world's largest medical center, but a new study indicates the region is also home to one of the lowest rates of health care workers among major U.S. metro areas.

The study, released by credit-building loan platform Self, shows the Houston metro area has 3.35 health care workers for every 100 residents. That places Houston at No. 10 on the study's list of the major metro areas (at least 1 million residents) with the lowest share of health care workers per capita, including doctors, nurses, and therapists.

The only other major metro area in Texas sitting toward the bottom rung of the ladder is Austin, with 3.17 health care workers per 100 residents. That puts Austin at No. 4 for the lowest rate of health care workers among major metro areas.

Houston's ranking in the Self study is juxtaposed with the city's status as a world-famous health care hub. Over 106,000 people work at the more than 60 institutions within the Texas Medical Center, which includes the University of Texas MD Anderson Cancer Center, Texas Children's Hospital, and the Baylor College of Medicine.

The 1,345-acre medical complex pumps an estimated $25 billion a year into the regional economy.

Despite Houston's stature as a medical magnet, the metro area is witnessing an escalating shortage of doctors and nurses.

A 2016 report from the Texas Department of State Health Services envisions the supply of registered nurses (RNs) — the largest group of nursing professionals — will climb 38 percent from 2015 to 2030 in the Gulf Coast public health region, compared with a 60.5 percent surge in demand. That equates to a projected shortage of 13,877 RNs in 2030. The Gulf Coast region includes the Houston area.

From 2017 to 2030, the supply of primary care physicians in the Gulf Coast region will increase 19.8 percent while demand will spike 27.5 percent, according to a 2018 report from the Texas Department of State Health Services. Ten years from now, the region will suffer a shortage of 694 primary care physicians, the report predicts.

In a 2019 survey commissioned by the Texas Medical Center Health Policy Institute, about 90 percent of primary care physicians across the country predicted a shortage in their field within five years. Seventy-eight of specialty physicians anticipated a shortage of specialists.

On the consumer side, the survey found 19 percent of patients reported difficulty scheduling an initial visit with a primary care physician, and 15 percent ran into trouble setting up a new visit with a specialist.

"The best way to tell if we have a doctor shortage is by asking patients whether they can easily get an appointment," Dr. Arthur "Tim" Garson Jr., director of the Texas Medical Center Health Policy Institute in Houston, said in a 2019 release. "For now, they overwhelmingly say 'yes.'"

By 2030, Texas will experience the third largest shortage of physicians among the states (20,420 jobs), according to a study published in 2020 in the journal Human Resources for Health. Only California and Florida will see worse shortages, the study predicts. The physician shortage in Texas is being driven by a growing population, an aging population and an aging pool of doctors, according to the study.

Noting the country's growing and aging population, a study published in 2019 by the Association of American Medical Colleges predicts the U.S. confronts a shortage of up to 121,900 physicians by 2032.

The looming national shortage of RNs is also acute.

The country's RN workforce is projected to grow from 2.9 million in 2016 to 3.4 million in 2026, or 15 percent, according to the U.S. Bureau of Labor Statistics. However, the bureau predicts the need for another 203,700 RNs each year from 2016 through 2026 to fill newly created positions and to replace retiring nurses.

"With patient care growing more complex, ensuring a sufficient RN workforce is not merely a matter of how many nurses are needed, but rather an issue of preparing an adequate number of nurses with the right level of education to meet health care demands," Ann Cary, dean of the Marieb College of Health and Human Services at Florida Gulf Coast University, said in a 2019 release

Houston medical device company heads to clinical trials following recent $2.8 million raise

HEalth tech

A Houston-based medical device startup is on a twofold mission to reduce healthcare costs and improve the safety of complex medical procedures involving blood vessels.

Saranas Inc. currently is testing its Early Bird Bleed Monitoring System, which is designed to detect and track bleeding complications related to endovascular procedures. These medical procedures treat problems, such as aneurysms, that affect blood vessels.

"What attracted me to Saranas is that our solution has the potential to meaningfully reduce serious bleeding complications that worsen clinical outcomes and drive up healthcare costs," says Zaffer Syed, president and CEO of Saranas. "In addition, our device may support access of important minimally invasive cardiac procedures by allowing them to be performed more safely."

Dr. Mehdi Razavi, a cardiologist with the Texas Heart Institute at Houston's Texas Medical Center, invented the device. It's being tested by the institute and other medical facilities in the U.S. As many as 100 patients will participate in the clinical trial, which is expected to last several months.

If all goes well, the U.S. Food and Drug Administration will approve Early Bird in 2019, Syed says. Then, the device would be made widely available to medical facilities across the country.

In May, Saranas said it received $2.8 million in funding from investors to enable testing of Early Bird. In all, the startup has collected $12 million from investors. A month after the funding announcement, Saranas was one of 50 startups chosen for the MedTech Innovator program, which nurtures medical technology companies.

As explained by the Texas Heart Institute, the Early Bird employs a sheath — a plastic tube that helps keep arteries and vessels open — embedded with sensors that measure the electrical resistance across a blood vessel. When the Early Bird senses a change in the electrical resistance, medical professionals get audible and visual notifications about potential internal bleeding. If detected early, this bleeding can be halted or prevented.

"There is a risk of bleeding that occurs when some of these coronary interventions are performed through the femoral artery, which is in the upper thigh," Syed says.

In a release, Texas Heart Institute cardiologist Dr. Joggy George says internal bleeding "remains the Achilles' heel" of advances in noninvasive endovascular procedures.

Syed says there's an underappreciation for how often bleeding occurs during nonsurgical procedures that provide access to a patient's blood vessels. Each year, doctors perform these procedures on more than 20 million patients in the U.S.; of those, about 1 million experience severe complications from bleeding. Those complications can lead to longer, more expensive hospital stays along with a higher risk of death.

Initially, Saranas is targeting high-risk endovascular procedures done with large sheaths, rather than endovascular procedures performed with sheaths of all sizes, Syed says.

Syed took the helm of Saranas in February 2017. He's spent nearly 20 years in the medical device industry, including four years at Bellaire-based OrthoAccel Technologies Inc.

For the time being, Syed is one of just a handful of employees at Saranas, which was founded in 2013 and has benefited from its affiliation with the Texas Medical Center Innovation Institute. Syed expects to grow the Saranas team in 2019 once the Early Bird gains clearance from the FDA.

During his tenure in the medical device sector, Syed has been "keenly interested" in bringing impactful innovations to the market, such as the Early Bird device.

"It is especially important to me that such innovation not only improves health outcomes but also aims to drive down healthcare costs," he says. "We are in a healthcare environment where if you don't have a health economic benefit coupled with a clinical outcome, it is very challenging to get adoption of new technology."

Efficient referrals from doctor to doctor could save a life, so this Houston company is setting out to create a network of medical professionals all accessible in an app. Getty Images

Houston-based company is connecting the dots on patient referrals

Diagnosing doctors

When your doctor recommends that you visit another practitioner, it's only natural that you trust the suggestion. But it's one case in which your physician isn't always an expert. Married doctors Justin Bird, an orthopedic surgeon, and Terri-Ann Samuels, a specialist in female pelvic medicine and reconstructive surgery, have long noted that patients are often referred incorrectly.

No big deal, right? Just go to another doctor. But not everyone has that luxury. Bird and Samuels never intended to start their own company. But when Bird lost a patient due to faulty referrals, they knew something had to be done.

"He believes that if she hadn't been bounced around from doctor to doctor, they could have saved her life," says Chris E. Staffel, chief operating officer of Patients We Share, the app that the couple created to fix the broken aspect of the health care system.

In 2015, Bird and Samuels began their company when they were shocked to realize that such an app didn't already exist.

"They started working with physicians around the country who said, 'We really, really need this,' and they also invested in it," recounts Staffel. From those friends, they built a physician advisory board of 15 investors.

Prescribing growth
The project was accepted into Johnson & Johnson's incubator, JLABS in 2016, then TMCx's digital startup program in the spring of 2018.

"They started realizing it was gaining momentum and realized they needed to have business people on board," says Staffel.

They hired Michael Antonoff, a Rice University M.B.A., as CEO. He invited former classmate Staffel to join as COO. Having come from a background in oil and gas, Staffel jumped at the chance to try her hand in a different industry.

With new business clout behind PWS, the company is growing quickly. Currently, PWS is entering its next seed round of $2.5 million that will allow the company to pay salaries of new team members and bring some tech development in-house. Until now, the making of the app itself has been outsourced to Mobisoft Infotech, a company based in Houston and India, which has worked on many projects at the Texas Medical Center. Local Black + Grey Studio is responsible for the design.

PWS has been working with both those teams in recent months to get a prototype app ready for launch. Currently, 100 physicians around the country are part of an invite-only pilot program. Soon, Staffel hopes to allow early adopter doctors who haven't been invited to enroll in the program for free. It will likely be in 2020 that patients will start joining the community, too.

How it works
An index of all the providers on the app allows doctors to easily find practitioners in a particular specialty. But there's more to it. Detailed profiles contribute to machine learning that assures the optimal match every time. Patient reviews will also play a role.

Though referrals were the impetus for the creation of PWS, it may be even more important as a communication tool between doctors, fellow clinicians (anyone from nurse practitioners to physical therapists may be invited to join), and patients. Staffel says participants in the pilot program are already using the messaging system to compare notes on cases, even sending photos from surgery to consult on patient issues.

The app's encryption means that it's HIPAA-compliant. Patients provide permission to discuss their cases via the app. And they can be confident of the quality of care they'll receive. Likely, the app will remain largely invite-only, and everyone who joins will share their National Provider Identifier licenses to be vetted against the federal database.

Doctors will communicate directly with patients through the app, but will also share resources digitally. Instead of making copy after copy of information about post-surgical care, for instance, the physician need only press a button to share a link.

Eventually, the goal is for PWS to be used not just nationally, but internationally, not just by individuals, but by whole hospital systems. A world in which doctors can compare notes around globe could be a little safer for us all.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”
