Close to half of the Houston area's general acute-care hospitals are at the top of their class, according to new safety grades assigned to U.S. hospitals. But one hospital in the region is failing on the safety front, the grades show.

In its fall 2019 report card for acute-care hospitals, The Leapfrog Group gives letter grades of A, B, C, D, and F based on the hospitals' ability to shield patients from avoidable errors, injuries, accidents, and infections. The nonprofit represents hundreds of public and private employers that buy healthcare benefits.

In the Houston area, 19 hospitals earned an A, with 14 receiving a B, seven getting a C, one picking up a D and one being slapped with an F.

Chris Skisak, executive director of the Houston Business Coalition on Health, notes that 23 percent of hospitals in the Houston areas saw their Leapfrog grades go up while just 11 percent saw their grades go down. The coalition is a regional leader for The Leapfrog Group.

"Houston-area hospitals do care about their grades," Skisak says, "and going back to 2016, most obtained a higher grade after receiving a lower grade the previous assessment period. Houston is fortunate to have [about] 50 percent of its hospitals earn consistent A grades."

For the first time in at least four years, The Leapfrog Group did hit one Houston-area hospital — Huntsville Memorial Hospital — with an F. On the spring 2019 report card, the hospital received a D. In the fall of 2018, the mark was a C.

Huntsville Memorial Hospital currently is combating what's been described as a "dire financial situation."

In a November 1 statement, the Walker County Hospital District, which owns the Huntsville hospital, said the separate nonprofit entity that runs the hospital — Walker County Hospital Corp. — was beset by monetary woes and was on the verge of declaring Chapter 11 bankruptcy. As a result, the district warned, the hospital might close.

According to The Huntsville Item, a proposed rescue of the hospital would place ownership and management in the hands of a joint venture between the hospital district and Plano-based Community Hospital Corp., a hospital management company. The nonprofit Plano company provides supply-chain services to a Huntsville medical practice, Huntsville Orthopedic Surgery and Sports Medicine PLLC.

In the statement, the district's board says it "remains committed to maintaining a viable hospital for the community and to improving hospital operations and services."

The Leapfrog Group graded a total of 42 hospitals in the Houston area. The nonprofit released its fall 2019 report card on November 7.

Houston-area hospitals that earned an A were:

  • Houston Methodist Baytown Hospital
  • HCA Houston Healthcare Conroe
  • HCA Houston Healthcare West
  • Houston Methodist Hospital
  • Houston Methodist West Hospital
  • Houston Methodist Willowbrook Hospital
  • Memorial Hermann Southeast
  • Memorial Hermann Southwest Hospital
  • Memorial Hermann Northeast, Humble
  • Memorial Hermann Katy Hospital
  • HCA Houston Healthcare Kingwood
  • CHI St. Luke's Health Memorial Livingston
  • Houston Methodist Clear Lake Hospital in Nassau Bay
  • HCA Houston Healthcare Pearland
  • Houston Methodist Sugar Land Hospital
  • CHI St. Luke's Health The Woodlands Hospital
  • Houston Methodist The Woodlands Hospital
  • Memorial Hermann The Woodlands Hospital
  • HCA Houston Healthcare Clear Lake in Webster

Skisak says the Leapfrog report card "is a valuable resource for employers to share with their employees so that they can self-navigate to the safest and highest quality hospitals."

"The Leapfrog Hospital Safety Grade offers critical patient safety information to consumers, in an easily digestible way, so that they can make informed decisions about where they seek care in the Houston area," he says in a release.

The Leapfrog Group bases its twice-a-year grades for hospital safety on 28 sets of publicly available data from more than 2,600 U.S. hospitals.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
