[Medical Human Story – Episode 71] The Last Breath Missed by AI: Systemic Sclerosis-2
Part II:
Clinical Intuition vs. Algorithmic Data
Time Omitted from the Dataset
"Why on earth did the artificial intelligence fail to
notice this?"
Inside the university hospital’s residency staff room, the voice
of Do-hyun, the young resident, shook with raw frustration.
His words carried a complex mix of deep bewilderment toward
cutting-edge technology and a sense of betrayal, as if he had been abandoned by
a system he believed to be infallible.
Having worshipped the absolute precision of medical informatics
and data-driven diagnostics since medical school, the psychological impact of
Seo-yeon’s misdiagnosis was staggeringly profound.
"Medical AI boasts about surpassing human limitations by
processing hundreds of millions, even tens of trillions of operations per
second. So why did it completely miss such definitive signs of systemic
sclerosis, dismissing them as mere dermatitis or transient
vasoconstriction?"
On the computer monitor, the analysis of a photograph of
Seo-yeon’s hands taken three months prior—generated by the AI diagnostic
software—remained on screen.
The AI’s final verdict read: Mild contact dermatitis
accompanied by Raynaud’s phenomenon, probability 89.4%.
The fatal term systemic sclerosis
had failed to appear even within the bottom 1% list of diagnostic
possibilities.
Watching this silently, Ji-hoon, the senior professor, let out a
heavy sigh and clicked his mouse.
With a sharp snap, the monitor screen went entirely dark.
Upon the pitch-black liquid crystal screen, the heavy, somber
faces of the two physicians—shadowed with the deep exhaustion of overnight
duty—were reflected like a mirror.
"Do-hyun, do you want to know why the AI failed? Computers
merely calculate two-dimensional patterns within fixed images and the
probabilities locked inside frozen pixels. Because it has learned from tens of
thousands of datasets, it can mimic the superficial appearance. But AI does not
understand 'time'."
"Time...? What do you mean by that? All timestamp data was
fully integrated into the system."
Do-hyun countered, visibly confused.
Ji-hoon leaned back against his chair and closed his weary eyes.
"The time I am speaking of cannot be quantified by numbers.
I am talking about the destructive sense of velocity—the sheer, cruel speed
with which this disease invaded that patient's fragile body, petrifying her
cells. I am talking about the inexplicable terror she must have felt turning
off the living room lights each night, watching her fingers freeze in the dark.
I am talking about the suffocating weight of time and the agonizing regret of a
family weeping tears of blood on the ICU floor, wishing they had come just a
little sooner... None of these human emotions or the organic flow of a person's
life exists within those flashy datasets and parameters. Data is always a mere
remnant of the past; it can never fully capture the living, breathing present
of a patient."
Do-hyun felt a heavy, suffocating constriction in his chest.
His mentor’s words were undeniably accurate, yet they served as
a brutal reminder of their harsh reality.
"Then... who ultimately bears the responsibility for this
catastrophic situation? Who is to blame for delaying the definitive diagnostic
window because we were blinded by the false high probability presented by the
AI? Is it the developer who wrote the algorithm, the machine that guided the
judgment, or the physician who signed off because they trusted the
numbers?"
Ji-hoon could not easily offer an answer to Do-hyun’s piercing,
heavy question.
To deliberate on blame was futile; the patient’s condition had
already drifted far too close to the precipice.
Inside the room, only the cold silence of the deactivated
monitor and the heavy respiration of the two men remained.
The Heat of the Multidisciplinary Conference
There was no more time to waste.
On the ICU monitors, Seo-yeon’s oxygen saturation levels were
tracing a steady, downward arc, her breaths growing shallower and more labored
by the minute.
At 2:00 PM, the doors to the Multidisciplinary Conference Room
on the fifth floor of the main building swung open heavily.
To grasp at the fraying thread of Seo-yeon’s life, leading
specialists from Rheumatology, Radiology, Pulmonology, and Critical Care
Medicine gathered in urgent haste.
On the massive screens lining the conference room walls,
Seo-yeon’s high-resolution chest CT (HRCT) scans and blood panels were
frantically displayed.
"If the radiological reading is correct, and this acute
respiratory failure is indeed due to Acute Progressive Interstitial
Lung Disease (ILD) secondary to systemic sclerosis, the situation is
catastrophic. We have no time to hesitate. We must initiate high-dose Methylprednisolone Pulse Therapy tonight, flooding her
system with steroids for three consecutive days, alongside aggressive
administration of cytotoxic immunosuppressants!"
The Rheumatology professor argued fiercely, his bloodshot eyes
fixed on the chart as he tapped the table with nervous energy. In his view,
halting the violent storm of immune cells was the absolute priority.
Instantly, the Pulmonology professor sitting across from him
furrowed his brow and shot back a counterargument.
"I object! Look at the imaging lines. The pulmonary
fibrosis has already progressed to a point of no return, rapidly approaching
the honeycombing stage. There is virtually no functional
lung tissue left. If we administer excessive immunosuppressants that completely
paralyze her immune system in this decimated state, a nosocomial opportunistic
infection or sepsis will kill her on the spot before we can even lift a finger!
Are we trying to treat the patient, or accelerate her death?"
"Then are you suggesting we sit on our hands and watch her
suffocate to death from respiratory failure? Is a doctor someone who abandons
treatment out of a fear of infection?"
The opinions of the two specialties clashed rigidly, neither
side willing to yield an inch.
The air inside the sprawling room grew instantly scalding, thick
with explosive tension.
Lost within the gray maze of a medical dilemma where no
statistical right answer existed, these human physicians agonized, hitting a
wall built of their own specialized knowledge and clinical convictions.
A machine would have effortlessly spat out a cold conclusion
based on a single number—like Survival Probability: 42%—but
because they were human, they could see the life of a woman and the future of
two young children hidden behind that statistic. They could not move their
hands so callously.
Yet, the time allowed to Seo-yeon was winding down to mere
hours. As the debate reached its boiling point, Ji-hoon, who had been silently
monitoring the volatile exchange, struck the table firmly and stood up.
The room fell into an instantaneous hush.
"If we waste any more time debating here, the patient will
succumb to respiratory failure tonight, long before we ever have the chance to
worry about an infection. If we refuse to wield the blade simply because we
fear its double edge, then we have no reason to exist as physicians. I will
take full responsibility as the attending faculty. Initiate the high-dose
steroid pulse therapy immediately."
It was not a safe, calculated course of treatment derived from
polished data or mathematical algorithms.
It was the product of a human physician's raw, agonizing tribulation—staking
an entire medical career to save a life for the sake of a single, solitary
percent of hope, despite the crippling fear of a fatal complication.
It was a blood-soaked, heavy 'decision' that only a human could
make—a true manifestation of noble responsibility.
