I’ve spent a lot of time thinking about the “last mile.” In logistics, that phrase means the final leg of a delivery. It is the point where a package leaves the distribution hub and actually lands on the customer’s doorstep (all those Amazon trucks you see every day). It’s the most expensive, unpredictable, and failure-prone part of the supply chain. Oddly enough, after years in podiatry, I’ve realized it’s not that different from what we do with diabetic foot care. Healing the wound is one thing. Keeping it healed, now that’s the last mile.
When I studied logistics in business school, I learned that the last mile could make or break the entire operation. You could have perfect inventory management, efficient routing software, polished warehouse systems, but if the driver can’t find the address, or the customer isn’t home, none of that matters. The product doesn’t reach the person it’s meant for. The last mile is where the sole meets the surface. In diabetic wound care, it’s the same. Everything we do leading up to wound closure (the offloading, debridement, infection control, etc.) means little if the patient doesn’t make it that final step to staying healed at home. That’s the last mile in medicine.
At WeTreatFeet, I see this play out often. A patient comes in with a chronic wound, usually a crazy history) something like my dog licked my right foot and now I have a wound on the left). We build a plan, execute it carefully, maybe even perform a minor surgical procedure when necessary. Then the wound granulates, the margins contract, the skin re-epithelializes, success! The wound is closed. But a month later, sometimes they’re back (it was the cat this time). Same area, same problem. That’s when I know we didn’t fully manage the “last mile.”
In logistics, the weak points are always the handoffs. Points where there is machine to human transfer, truck to porch, etc. In healthcare, it’s clinician to patient. The transition from clinic to home is our critical handoff. I’ll admit, it’s where many care plans falter. Once the patient leaves the controlled environment of our office, the variables explode: offloading compliance, blood sugar fluctuations, poorly fitting shoes, even how their floors are at home (I didn’t realize there was a tack strip holding down my carpet). These small, easily overlooked details can derail weeks of progress. I’ve had patients heal beautifully only to develop a new callus in the same spot because they went back to an old pair of sneakers. That was their version of the driver missing the turn.
One thing logistics taught me is to never assume the process ends when the truck leaves the warehouse. You track, confirm, and follow up. We should take that same mindset to diabetic wound care. I’ve started thinking about discharge from wound care the same way I used to think about delivery confirmation. There’s a protocol, a checklist, a final verification that the care plan is being executed where it matters, the patient’s day-to-day environment.
This is where education and accountability come in. Patients who stay healed typically have one thing in common, they understand the “why” behind every instruction. I can tell someone to wear their diabetic shoes 100 times, but unless they connect that to real consequences (This relieves pressure where the tissue broke down), it doesn’t stick. In logistics, technology helps track that endpoint, barcode scanning, delivery photos, GPS markers. In medicine, we rely on something less tangible, trust and repetition. Sometimes it’s a phone call. Sometimes it’s a follow-up visit sooner than we would like. Whatever it takes to make sure that “package” (healing), arrives safely and stays there.
Of course, the analogy isn’t perfect. Healing human tissue involves biology and behavior, not just route optimization. But the systems-thinking part of me loves the comparison because it forces us to consider efficiency, reliability, and sustainability as clinical goals. Healing a wound is an achievement. Keeping it healed is a system.
I’ll give you an example that still sticks in my mind. A retired bus driver with long-standing diabetes came to us after two failed wound treatments elsewhere. Big plantar ulcer. Debrided, infected, and unhealthy. I started the treatment (the order) and worked to reduce weight and improve glucose control (the delivery). After eight weeks, he was healed (package in hand). We celebrated this achievement. Then, three months later, he returned with another ulcer, same location. Turns out his daughter had bought him a pair of shoes she thought would help (extra wide, they have a different definition of this than I did) without an offloading insert. That one small deviation reopened everything. That’s the “missed delivery.” Everything before that had gone according to plan, right up to the final handoff. I learned that day to never assume the last mile is in place until I see it myself.
In logistics, you map routes meticulously, but the street-level variables still get you: weather, traffic, construction, misplaced addresses. Same idea goes for wound healing. The vascular flow can look great, the A1C numbers can be acceptable, but one pressure point under a metatarsal head can undo everything. So, like a logistics manager anticipating delays, I’ve learned to plan redundancies. I allow for extra follow-up appointments, shoe evaluations, nursing check-ins. If there’s one thing that I’ve learned in 25 years of treating diabetic feet, it is that healing is a process, but staying healed is a promise we make together.
There’s another parallel to also consider. It is the data. In logistics, you track every metric: cost per mile, on-time rate, failed deliveries. In diabetic wound management, we also have data, items like wound size, duration, ABI, infection markers. What we rarely measure is post-healing durability. How long does the wound stay closed? This is the metric I want to optimize. A “healing durability index,” if you will. Because once we start measuring it, we can improve it. That’s how logistics transformed from guesswork into precision science, and in medicine, we should do the same.
Something else I’ve taken from my business training, lean courses, (school of hard knocks ) is to take pride in the small victories. A perfectly delivered package. A healed wound that stays closed for a year. Neither happens by luck, they both happen because of dozens of tiny decisions lined up just right. The driver took the time to triple-check the address. The patient decided not to walk barefoot, even once. These micro-choices define whether success holds.
Honestly, that’s where the human side of medicine still amazes me. You can design the best offloading device, optimize the antibiotic regimen, digitize every wound photo, and it is still about relationships. Logistics systems depend on drivers showing up and customers being home. My clinical outcomes depend on patients showing up, both mentally as much as physically. When they understand that “last mile” belongs to them, healing shifts from something I do for them to something we do together.
So if there’s one thing these very different, yet exactly the same concepts have taught me, it’s this, systems fail where communication ends. In logistics, that means an undelivered box. In diabetic wound care, it means a patient who heals but doesn’t stay healed. Every time I see a wound close now, I think about the delivery truck pulling up to the house. The job isn’t done until it’s safely inside (and the amazon drivers stop blocking each other in).
That’s the last mile. And for anyone living with diabetes, that mile is where everything counts. It is the difference between healing and hospital, between independence and another round of treatment. So as a doctor, my job isn’t just to close wounds. It’s to make sure the healing gets delivered, and stays delivered.
