Four years of data from MLK Community Healthcare show what happens when you build diabetic foot care around the patient — in exactly the place the map says amputations should be worst.
I started writing this from our Limb Preservation Clinic, where I had just finished seeing a patient facing a high-level amputation. We are working like mad to keep him moving through the world. It is the kind of fight that defines our days — and, too often, the kind we enter too late.
A few hours later a report crossed my desk that made me sit back and grin, then read it again, then reach for the blog. The headline is a single, gorgeous number: zero.
Over the fourth year of its diabetes program, MLK Community Healthcare (MLKCH) in South Los Angeles recorded zero diabetic lower-extremity amputations among the highest-risk patients in its intensive management program. Not a low number. Zero. In a community where, just a few years ago, amputation was among the most common operations the hospital performed.
If you have spent any time in this field, you know how hard that word is to earn.
What MLK built
South LA carries one of the heaviest diabetes burdens in the country — roughly 37% higher prevalence than Los Angeles County overall — layered on top of the access barriers that turn a manageable chronic condition into a surgical emergency. This is Service Planning Area 6: predominantly Latino and Black, predominantly low-income, and historically underserved by specialty care.
In 2021, with lead support from the Good Hope Medical Foundation and matching support from the Rose Hills Foundation, MLKCH launched a Diabetes Management Center of Excellence. The four-year analysis — authored by Jorge Reyno, MD, MHA, and Kristalee Lio, MS, and independently reviewed by the UCLA Center for Health Policy Research — covers nearly 5,931 enrolled patients, including 1,165 in intensive disease management, in a population that is about 63% Hispanic/Latino and 23% African American.
The model is refreshingly unglamorous. Every patient with diabetes is enrolled in a coordinated registry. The highest-risk patients — type 1, gestational, an A1c of 9.0% or above, or a physician’s gut feeling — graduate up into intensive management with a dedicated, multidisciplinary team. And once they are stable, housed, and self-managing, they graduate out, freeing the slot for the next person who needs it. Of the 19 who have graduated so far, 91% have held their A1c control.
The number that matters
Here is the contrast that should stop you:
- Intensive cohort, Year 4: 0 amputations.
- Regular cohort: 363 per 100,000 (90-day rate).
- Surrounding SPA 6 community: 494 per 100,000 residents with diabetes.
Across the entire four-year grant period, the intensive cohort’s cumulative amputation rate (AHRQ’s PQI-16, 90-day window) was 86 per 100,000 — against 390 for the region. The single amputation that did occur in that cohort over four years happened 29 days after enrollment, in a patient who walked in the door with advanced peripheral arterial disease already well underway. In other words: the program didn’t fail him; the clock had run out before he ever arrived.
And the amputation numbers don’t stand alone. They sit on a foundation of the things that prevent amputations:
- 81% A1c control in the intensive cohort (85% for those enrolled nine months or longer) — beating the CMS national Medicaid benchmark of 64% and the LA Care benchmark of 68%. A safety-net population is not supposed to outscore the nation. This one does.
- 71–74% blood pressure control, also above benchmark.
- Foot exams up from 46% to 65% in a single year, and nephropathy monitoring at 95%.
- Appointment compliance of 84%, up from a 50% pre-program baseline — which, if you ask me, is the quiet hero of the whole report. Outcomes follow relationships.
Why this isn’t luck
Regular readers know my hobbyhorses, so let me connect the dots.
About 80% of diabetes-related amputations are preceded by a foot ulcer (Armstrong, Tan, Boulton, Bus, JAMA, 2023). That single fact is the most hopeful in our field, because it means the amputation is the last domino — and there are many earlier ones we can knock down. MLK knocked them down on purpose:
- A true toe-and-flow, team-based model — primary care, endocrinology, a clinical pharmacist optimizing medications, RN care managers, a diabetes educator, behavioral health, and community health workers (Promotores) doing home visits.
- Remote monitoring with BlueDrop thermovisual foot scanning, catching ulcers at Stage 1, before the patient even feels them. This is exactly the “predict and prevent” posture we keep arguing the field must adopt.
- Social determinants treated as clinical variables, not afterthoughts: the Recipe for Health food-access program, the Know Your Basics mobile screening van (1,508 screenings in Year 4 alone), and the wonderful ManUp! barbershop health-education program meeting people where they actually are.
None of these is exotic. The achievement is that someone funded them, integrated them, and stuck with them for four years in the population that needed them most.
What a limb is worth
We don’t talk about the money enough, so let’s. The team estimates that preventing a single lower-extremity amputation avoids somewhere between $70,000 and $500,000 in direct and indirect costs; the recent literature pegs five-year costs per amputee at north of $500,000 — nearly double the lifetime cost of a comparable person without limb loss.
Zoom out and it’s even starker. Roughly one-third of the direct medical costs of diabetes in the United States are spent on the lower extremity — on the order of $100 billion a year when applied to the most recent ADA figures. That is, by itself, comparable to what we spend on all of cancer. And the mortality matches the price tag: five-year mortality after a major amputation runs near 57%, rivaling or exceeding many cancers.
Which is why I keep insisting we reframe the healed foot the way oncology reframes the healed patient — not “cured,” but in remission. A state that demands structured surveillance, not a discharge and a handshake. MLK’s graduation-and-monitoring model is, functionally, a diabetic-foot survivorship program. They may not have called it that. But that’s what it is.
The honest part
I want to be the scientist as well as the cheerleader, because credibility is the only currency that matters here.
This is a single-system program report, not a randomized trial. The comparisons lean on historical baselines and regional benchmarks rather than a concurrent control group, and the intensive cohort was selected by severity. The authors say all of this themselves, plainly, which is exactly what gives me confidence in the rest.
And note the direction of that selection bias: the intensive cohort is the sickest group — 70% with cardiovascular disease, 31% with chronic kidney disease. Sicker patients should have more amputations, not fewer. They had zero. That doesn’t weaken the result. It makes it louder.
ZIP code, meet genetic code
I have said for years that, when it comes to amputation, your ZIP code is a more powerful predictor than your genetic code. The data are unkind about it: Black Americans with diabetes are up to four times more likely to lose a limb than their white counterparts, and in our cities every $10,000 drop in neighborhood income tracks with a measurably higher amputation rate. The map of American amputation is, to a heartbreaking degree, a map of American poverty.
So here is what makes this report sing. It didn’t happen in a gleaming academic tower. It happened in 90059 — in precisely the ZIP code the map says should be worst. The communities at the bottom of every disparity chart are also the communities where prevention buys the most. MLK just proved it, four years running.
Zero is not a fluke, and it is not a finish line. It is a demonstration. It says that ulcer-free, hospital-free, activity-rich days are achievable for the people most likely to be told they’re impossible — if we are willing to build the team, fund the boring parts, and stay.
Hats off to Dr. Reyno, Kristalee Lio, the entire MLKCH diabetes team, and the foundations who bet on them. This is life-affirming stuff. Go read it.
