The Typing Mistake and the Empty Notebook
In General Surgery Ward 4's station, an endless cascade of treatment orders flooded the EMR system screen. It was three in the afternoon, and Baek Ijun stared into the monitor's blue glow as he cross-verified the medication lists for the newly admitted patients. Data from dozens of patients flowed through Ijun's optic nerves with cold precision, like passing through a vast computational circuit.
His gaze halted at the medication order window for the patient in room 602. She was a woman in her sixties, admitted for deep vein thrombosis and receiving a continuous infusion of the anticoagulant heparin.
At that moment, the Archive's fourth tab, which had been idling at the edge of his vision, flashed with a faint red light from the Warning icon.
Target: Room 602 Heparin Administration Dosage
Observation: Input dosage exceeds appropriate level by 10 times relative to patient's weight and coagulation values. Fatal systemic bleeding trajectory predicted.
The order displayed on screen called for 15,000 units per hour. Based on the patient's biological markers and standard treatment algorithms, the correct figure was 1,500 units. A simple but most lethal variable—one extra zero in a clear case of data entry error.
If the prescription passed through the network to the ward and entered the patient's vein, she would face an uncontrollable catastrophe—cerebral hemorrhage or massive internal bleeding—within hours.
Ijun closed the screen at once and walked over to Chief Resident Oh Jae-hyeong, who was drafting a consultation request at the back of the desk.
"Sir, I've confirmed that an extra zero was added to the heparin IV order for the patient in room 602, resulting in a tenfold dosage," Ijun said. His voice carried no trace of accusation or urgency, only the dry, precise delivery of information.
Oh Jae-hyeong's hand froze above the mouse. He immediately pulled up the chart for room 602. As his eyes scanned the screen, a heavy blend of bewilderment and chill swept across his face.
The air in the station grew thick. After several seconds of taut silence, Oh Jae-hyeong clicked the cancel button and re-entered the order with the correct dosage.
"It's just a typing mistake," Oh Jae-hyeong muttered, his voice a tone lower and drier than usual. It was the defensive reflex of someone higher in the system, attempting to bury a potentially lethal error beneath a single innocuous phrase.
Ijun did not press into the emotions or sense of authority lurking behind those words.
"I will immediately notify the nursing station of the corrected order at the proper dosage to ensure prompt administration and completion of treatment."
With that single sentence clearly mapping his next action, Ijun returned to his station. Oh Jae-hyeong offered no reply, eyes fixed on his monitor.
The error was quietly corrected within the system, and the patient's hemodynamic safety was secured. To Ijun's calculations, the incident had been perfectly resolved.
Yet the vast system of a university hospital did not run with the transparent honesty of a mathematical equation.
At eleven that night, when the on-duty shift began in earnest, Ijun's call phone vibrated with such violence it seemed ready to shatter. The caller was the night chief, Oh Jae-hyeong.
"Three patients transferred from another department to Ward 7. Write up all their admission summaries yourself and upload them to the system."
It was a brutal administrative burden—taking histories, deciphering surgical records from other hospitals, untangling complex current medications, and condensing everything into dozens of pages of coherent chart notes. The call cut off before Ijun could respond.
The transferred patients' past records might as well have been written in code. Decoding illegible abbreviations scrawled by other departments and reconstructing fragmented patient histories into logical medical documents demanded enormous mental energy.
The Archive excelled at revealing intra-abdominal pressure or subtle signs of vascular rupture, but it remained completely silent when faced with the daunting task of filling digital fields with text.
An hour later, halfway through the first summary, the phone rang again.
"Intestinal obstruction case just came up from the ER to room 508. Go insert an L-tube and start decompression right now."
Ijun minimized his current window, grabbed the nasogastric tube kit, and ran to room 508. The patient, wracked with severe nausea and abdominal pain, offered zero cooperation. During the minute it took to advance the thick plastic tube through the nose, esophagus, and into the stomach, the patient's retching and saliva soaked Ijun's gown sleeve.
No matter how perfectly he visualized the anatomical path, controlling a writhing, suffering body while advancing the tube was pure emotional labor and physical drain.
"Sir, once this tube is in, the gas trapped in your stomach will be released and you'll breathe much easier," Ijun said in a calm, generous tone, finally completing the procedure.
The moment he confirmed the cloudy exudate draining from the patient's stomach and sat back at the station, the third call came.
"The guardian consent form for room 412 is missing a signature. Get it again and scan it in."
It could not be officially classified as retaliation. Every order fell within the legitimate scope of on-duty responsibilities for a first-year resident. Oh Jae-hyeong was simply dumping every minor, time-consuming task he could have handled himself—or would normally have delegated to an intern—directly onto Ijun.
He was masking his displeasure at having his earlier critical error discovered by a first-year beneath a barrage of legitimate work.
The guardian unleashed sharp irritation at being woken at three in the morning to sign administrative papers. Ijun absorbed every emotional blow in silence and upheld the hospital's protocols to the end.
Two in the morning. Three in the morning. Ijun's footsteps traveling the length of the ward grew heavier, like lead weights.
When it came to opening abdomens, analyzing vascular tension, or detecting invisible trajectories of inflammation, the Archive implanted in his brain shone brilliantly. But in the grueling war of attrition—restraining dementia patients' limbs to complete procedures, absorbing the complaint-filled irritation of guardians roused at dawn, and patiently explaining hospital principles—the Archive offered no solutions.
The hospital's true system was entangled not only with biological errors called disease but with boundless human emotions, power relations, and the chains of merciless administration.
In this uncontrollable swamp, the cutting-edge visualization layer was as powerless as a machine with its plug pulled.
At four in the morning, after uploading the scanned files of the final administrative order Oh Jae-hyeong had thrown at him, Ijun sank into a simple chair in the empty on-call room.
Beyond the window, the pitch-black darkness before dawn lay heavy. Every muscle screamed. The nonstop computational load in his brain had reached its limit and now creaked dully. Even the old fluorescent light in the on-call room felt like it was stabbing his retinas.
Ijun slowly slipped his hand into the inner pocket of his sweat-soaked, crumpled gown. His fingertips brushed against a small, worn notebook—one he had carried constantly but never opened.
He took it out and laid it across his lap. Turning the frayed cover revealed a blank white page with a rough, fibrous texture.
The Archive perfectly revealed the anatomical truths and pathological errors of the human body. In predicting hemodynamic collapse and guiding the scalpel's path, it touched the realm of the divine.
Yet when faced with the irrational trajectories of the giant organism known as Korea University Hospital and the variables of human groups, it was utterly blind.
Oh Jae-hyeong's typing mistake. The legitimate dawn violence unleashed by systemic power to bury that fatal error. The verbal blows from dissatisfied guardians and the crushing responsibility shifted onto a first-year resident.
To navigate these undercurrents and survive, he needed something beyond the Archive's lens—a new algorithm of his own.
He had to record it.
The system's blind spots. The unpredictable variables born from other people's emotions. The new survival formula a first-year resident with meager authority must construct to endure the political dynamics of this massive hospital.
But Ijun did not reach for the pen in his chest pocket. He could not even define the first proposition to write on that blank page.
Machine error codes were intuitive and clear, but the power-based errors of a hospital system woven from human relationships had not yet been fully translated into his language.
In the on-call room where silence lay heavy at dawn, Ijun simply held the empty notebook open, silently watching the cold blue light of daybreak gradually spread beyond the narrow window.
A new battlefield—impossible to decode with machine power or medical textbooks—lay spread before him, vast and daunting.
