New MLK hospital program brings amputations to zero for at-risk diabetic patients

More than three decades after a diagnosis of Type 2 diabetes, Michelle Caldwell says her disease is better controlled than ever.

She keeps regular appointments with her endocrinologist, primary care provider, dietician and pharmacist at MLK Community Medical Group, the outpatient arm of MLK Community Healthcare.

She picks up weekly produce deliveries in the South Los Angeles hospital’s cafeteria and attends its occasional cooking classes. She has learned to decode nutrition labels and developed a taste for salads and nuts.

Just one hurdle remains: the shoes.

Diabetes can damage foot nerves, making it easier for patients to miss small scratches and wounds that could lead to serious infections. Her care team was gently urging her to switch to supportive, closed-toe footwear.

But Caldwell loves a sandal, and the podiatrist-approved options were crimping her style.

“It doesn’t have to be, like, fashion fashion,” she said with a laugh during a recent visit with primary care provider Dr. Edward Cardenas at his East Compton office. But were there any options that didn’t look like “Frankenstein feet”?

That down-to-the-toes level of care is a feature of a program that has transformed the way MLK Community Healthcare treats diabetes, a chronic condition that affects one in every six South Los Angeles residents and nearly a quarter of MLK’s outpatients.

Four years after MLK launched an intensive management program for the most at-risk patients, more than 80% of enrollees have seen blood sugar levels decline. More than 70% have brought their blood pressure under control.

And diabetic-related amputations — which are painful and life-altering procedure that were the hospital’s most common surgery for years — have plummeted to zero for program patients.

No novel medications or treatments are behind these results, said Dr. Jorge Reyno, MLK’s senior vice president for population health.

Rather, a relatively modest one-time grant has allowed the hospital system — whose service area includes some of L.A.’s poorest and most disadvantaged neighborhoods — to provide the same level of care for its diabetic patients that people in wealthier areas would expect as standard.

“What we’ve demonstrated here is that we can get best-in-class care — we can even beat national benchmarks for care — if there’s the appropriate commitment and investment. And that people’s health doesn’t have to be determined just by their zip code,” Reyno said. “Because what we’ve created here is not necessarily incredibly innovative. It’s just what needs to be available — and is available in other locations.”

Some 1.3 million people live in MLK’s South Los Angeles service area. More than 90% are Black or Latino, and nearly 70% are either uninsured or have health coverage through Medi-Cal, Medicare or both.

Medi-Cal’s low provider payment rates is one reason South L.A. has only one-third of the full-time physicians necessary to treat a population of its size — a 1,500-doctor shortage, according to MLK’s research.

For many locals, MLK’s emergency department is about the only place they can see a doctor, given the challenge they face securing a timely appointment with a physician who accepts their health coverage.

Roughly 123,000 patients arrived last year at the hospital’s emergency department, which was designed to treat 40,000 people annually. About 40% were seeking primary care.

Emergency room physicians were diagnosing diabetes in severely ill people who did not know they had the disease and treating life-threatening complications for those whose disease had long gone unmanaged.

Patients arrived with gangrenous foot wounds that harried providers elsewhere brushed off as athlete’s foot. Rates of diabetic ketoacidosis, a life-threatening complication that occurs when insulin levels are so low that cells can no longer convert glucose into energy, were three times that of the rest of Los Angeles County.

For many, care arrived too late to prevent one of the disease’s most serious complications: amputation.

Nerve damage means a blister or pebble in the shoe can go unnoticed until it creates a serious wound. High blood sugar impairs immune function and narrows vessels that carry oxygen-rich blood, making it harder for skin to heal. Once serious infection sets in, amputating a foot or limb may be the only option to save a patient’s life. Across the U.S., diabetes complications are responsible for roughly 80% of all non-trauma related amputations, according to the Centers for Disease Control and Prevention.

Broaching amputation with a patient “is really tough,” Cardenas said. “You’re taking such a big part of them away. It’s identity, it’s confidence, it’s [the] ability to walk and do things for themselves. It’s a huge, huge thing.”

It’s also costly. Diabetes cost $306.6 billion in U.S. direct medical spending in 2022, the most recent year for which numbers are available, and foot ulcer-related issues were responsible for about one-third of that, said Dr. David G. Armstrong, director of USC’s limb preservation program and the Southwestern Academic Limb Salvage Alliance.

Indirect costs are also steep. One study of post-surgery outcomes found that only about one-third of patients were able to return to work after the amputation surgery, despite an average age of 54.

“The economic ramifications aren’t just the fact that you’re not working. It’s also that people in your family are taking off of work to be able to help accommodate this, or having to provide extra resources that they previously weren’t having to, so it has sort of a multi-generational effect,” said Dr. Caitlin Hicks, a vascular surgeon and director of research at Johns Hopkins University’s Multidisciplinary Diabetic Foot and Wound Clinic.

In California, the households most likely to bear that cost are those that can least afford it.

Diabetic residents in MLK’s service area and other economically impoverished parts of California were more than 10 times more likely to have a toe, foot or leg amputated than diabetic people in more affluent areas, according to one 2014 UCLA study.

“The finding that residents living in lower income areas bear a disproportionate share of disability and disfigurement from amputations is deeply disturbing in a society that espouses equality and outspends all other nations on health care for its more affluent citizens,” the paper’s authors wrote.

It was a problem MLK decided to do something about.

The hospital secured a $2 million grant from the Good Hope Medical Foundation, a private foundation based in Pasadena, with additional funding from the Rose Hills Foundation and L.A. Care Health Plan.

In October 2021, it began officially enrolling patients in its Diabetes Management Center of Excellence. Within this was an intensive-management program for a subset of high-risk patients, including those with Type 1 diabetes, gestational diabetes or hemoglobin A1C levels — an indicator of blood sugar — at 9.0% or more. (For people without diabetes, a level below 5.7% is considered normal.)

For the most part, the system already had the endocrinologists, nephrologists and primary care physicians it needed. The money let MLK build a network of dedicated support staff who could take care of diabetic patients outside the exam room.

Between visits, patients in the intensive-management program had access to a clinical care pharmacist who reviewed and coordinated medications; a diabetes educator who walked them through blood sugar monitoring, meal planning and other daily concerns; community health workers who could make home visits; and a nurse care manager who served as their primary advocate and point of contact.

Through the hospital’s Recipes for Health program, they could pick up weekly bundles of fresh produce and take bimonthly classes on diabetic-friendly recipes.

They were more likely to stick to their treatment plan, and had more time at doctor visits to discuss medical issues.

“We have multiple people reaching out and interacting with the patients in between physician visits,” said MLK endocrinologist Dr. Megan Jacobs. “They have someone reaching out to them [and] talking to them about the social aspects of things — how they have to take into account their diabetes when they go out to dinner and when they’re at a party.”

By year three, 66% of patients in the intensive-management program had lower blood sugar levels than they did at enrollment; by the fourth year, 81% did. In the third year 63% of patients had brought their blood pressure under control, rising to 71% the following year.

Four years after the program started, appointment compliance hit 84%, up from 50% at baseline. The hospital’s most severely diabetic patients were hospitalized for diabetes at less than half the rate of the area’s general population.

Most significantly, amputations among the intensive-management group dropped to virtually zero.

Over the course of four years, only one of the 1,165 patients in the high-risk group required an amputation. The surgery took place less than a month after their enrollment, indicating they likely entered the program with a wound at critical levels.

Diabetic-related amputations and wound care are now MLK’s third-most common type of surgical procedures, after holding the top spot since the hospital’s 2015 opening.

“This is absolutely, positively spectacular,” USC’s Armstrong said of MLK’s results. “This is life affirming stuff.”

The primary grant ends next year. After that, the program’s future is uncertain.

MLK is eligible to reapply to the Good Hope Medical Foundation, which has been “very happy” with the program’s outcomes, said Howard A. Kahn, the foundation’s chair.

The hospital is also talking to L.A. Care, the largest publicly operated health plan in the U.S., about a potential partnership, Reyno said. It could be a win for both sides.

“The benefit of cost savings usually goes to the state Medicaid plan or to the insurance carrier, who doesn’t have as high a cost to pay,” Reyno said. “If a program like this could be replicated in other safety net communities and have a wider impact, then certainly the return on investment would be even greater.”

Care providers also said they see improvements the data doesn’t capture.

“I hear [patients] say, ‘Oh, I walked to the park with my grandchildren,’ or ‘I was able to move around because I’ve lost the weight’ … maybe they had a sore on their foot that was kind of questionable, [and] ‘Now it’s healed because my sugars are under control,” said nurse care manager Monica Garcia. “Just seeing the benefits when they are compliant is the satisfaction.”

Back at the clinic office in East Compton — the shoe issue set aside for now — Cardenas examined Caldwell’s feet and lower limbs.

The doctor was optimistic that Caldwell’s recent discomfort came from tight muscles, rather than nerve damage, and recommended a stretching and strengthening regimen.

“It shouldn’t be painful, just like a tug,” he said, demonstrating a standing calf stretch. “If you like, I can refer you to physical therapy as well.”

Having providers take the time to explain her disease, rather than just scribbling out prescriptions, has made a world of difference for Caldwell, she said.

“It’s an awesome experience. I’ve changed my eating habits, I’m learning to read labels more clearly,” she said. “Even at my age, you think you know, but you don’t know.”

Nobel Prize winner leaving UC Berkeley for new role in China

Nobel Prize recipient Omar Yaghi is leaving his role at UC Berkeley to lead the development of a new artificial intelligence institute at Tsinghua University in Beijing, the Chinese university announced.

Yaghi will head the AI Chemistry and Materials Research Institute at Tsinghua, where he was appointed an honorary professor in 2022. Known as AIMATRY (AI × Materials × Chemistry), the new center will focus on material design and synthesis through artificial intelligence, according to a statement from the university.

In 2025, Yaghi shared the Nobel Prize in chemistry with Susumu Kitagawa of Kyoto University and Richard Robson of the University of Melbourne for their development of metal-organic frameworks, a type of super-porous material in which metal ions and carbon-based molecules combine to form crystals with exceptionally large surface areas.

The material has the potential to combat climate change by capturing and storing carbon or other pollutants, and by extracting water from the atmosphere in water-scarce areas. Upon awarding the prize, a member of the Nobel committee likened the technology’s ability to store enormous amounts of stuff in seemingly compact spaces to Hermione Granger’s enchanted handbag in the Harry Potter series.

Yaghi’s Irvine-based company, Atoco, has said it will start taking orders later this year for its technology that harvests water from the air.

A representative for Yaghi said he was not yet available to respond to questions.

China is one of several countries that has been actively recruiting scientists from the U.S., where the Trump administration has slashed science funding, suspended research grants, fired science advisors and tightened immigration restrictions.

“For many, many years, our funding was very competitive; if you worked hard and you were doing good research, you would get funding,” Yaghi said of the U.S. in an interview with Scientific American earlier this year. “The current state is not so encouraging because of the cutting back on grants and support of science by the very agencies that many university researchers rely on.”

Yaghi was born in Jordan to Palestinian refugees, and immigrated to the U.S. when he was 15 to study.

“We’ve learned over and over in human civilization that scholars can move across borders,” Yaghi told the New York Times last year. “This is how knowledge spread and how vast regions of the world lifted themselves out of poverty.”

Trump administration seeks to limit federal funding that doesn’t ‘advance’ presidential policies

Trump administration seeks to limit federal funding that doesn’t ‘advance’ presidential policies

A new rule proposed by the White House Office of Management and Budget would fundamentally overhaul the way federal grants are awarded and overseen — a sweeping change that one scientific society said “would all but end the use of scientific merit in the selection of grants and programs across the government.”

Proposed in late May, the rule would give political appointees unprecedented control over federal grants for research, education and infrastructure, and specifies that government funds can only be spent on projects “aligned with administration policies and priorities,” according to a copy of the proposed rule.

The rule would also restrict research topics, limit U.S. scientists’ ability to collaborate with colleagues in other countries and make it easier for the government to suspend or cancel grants at any time.

The changes are intended to improve “transparency, accountability, and oversight for Federal awards” while “ensuring that American tax dollars are not wasted or misused,” according to the White House office.

But critics say that if the rule is implemented, the final sign-off for grants will no longer be in the hands of subject-matter experts within individual agencies, but in those of political appointees.

“This touches all parts of American life,” said Dr. Eric Rafla-Yuan, a psychiatrist who practices at the Veterans Administration and San Diego County’s psychiatric hospital.

“Control of how all of the federal grants and programs are funded will fall under a small group of highly partisan individuals who would have very few limits on how they spend these billions of taxpayer dollars,” said Rafla-Yuan, who also chairs the Committee to Protect Public Mental Health advocacy group. “This touches everyone’s life, even if they don’t realize it.”

OMB published the proposed rule May 29, opening a 45-day comment period that closes July 13.

Opposition to the proposed rule has mobilized multiple sectors of society. Professional groups representing cancer researchers, civil engineers, county governments, medical schools, housing agencies, city and municipal governments, nonprofits and others have publicly expressed concerns about potential consequences.

By midday Thursday, the Federal Register logged nearly 100,000 comments about the proposal, many of them expressing concern.

“I understand the need for oversight, fiscal responsibility, and accountability. That is not the issue,” wrote Jack Feldman, a neuroscientist who holds the David Geffen School of Medicine Chair in Neuroscience at UCLA. “The issue is whether scientific research is to be judged by scientific merit, or whether it can be approved, denied, or terminated according to broad political criteria that may change from one administration to the next.”

Crucially, the rule converts policies governing federal grants from “guidance” into binding regulations that all agencies would be required to follow. It would give political appointees power to override federal agencies’ merit-based reviews and mandate that a political appointee review decisions to ensure that all awards “demonstrably advance the President’s policy priorities.”

The elevation of political appointees in what were previously merit-based decisions has alarmed many scientists.

“The proposed rule changes would all but end the use of scientific merit in the selection of grants and programs across the government,” read a statement from the Planetary Society, a nonprofit dedicated to space research.

Researchers and science groups have also expressed concern about a section of the rule prohibiting the promotion of “theories of disparate-impact liability” — a legal concept that refers to policies that appear neutral but cause disproportionate harm to certain groups.

The section’s vague language and many loopholes could have a chilling effect on any research that studies the effects of a disease, policy or public health intervention on any specific group of people, Rafla-Yuan said.

As an example, he said, “if there’s a specific age range that is at higher risk for suicide, and we want to figure out, well, what’s going on with people that are aged 14 to 19 … we can’t do that under the wording in this rule.”

New restrictions on collaborations with scientists in other countries would hinder opportunities for U.S. researchers and limit innovation, said Joanne Padrón Carney, chief government relations officer for the American Assn. for the Advancement of Science.

“Science is a global enterprise. Especially in biomedical and public health fields, diseases don’t care about borders or government policies,” she said.

California’s congressional delegation sent a letter Wednesday asking OMB to rescind the proposal, outlining concerns about its impact on scientific innovation, U.S. competitiveness and the fiscal stability of local governments, many of which rely on federal grants for local services.

The proposed rule grants the federal government broad powers to suspend or cancel grants for any reason, introducing “unprecedented unpredictability into local governance,” the lawmakers wrote, “leaving vital infrastructure projects unfinished and abandoning vulnerable populations who rely on these services.”

Republican Sen. Susan Collins has also asked the White House to withdraw certain parts of the letter and extend the public comment period, saying the proposed rule as written would “harm small and rural communities, undermine scientific and biomedical research, and conflict with Congress’ control over the federal funding process.”
