The Triage Override

The ethics committee meets in a windowless room on the third floor, which Luana has always suspected is deliberate. Today's agenda has one item, printed in bold. It asks whether the hospital's triage ranking, which sorts the emergency department's waiting patients by predicted risk, may be overridden by a nurse's judgement and, if so, on what terms. Luana, the committee's lay member and a retired statistician, has read the validation report twice. She trusts the numbers. What she does not yet trust is the sentence "the system is correct in ninety-four per cent of cases".

Komite etik bertemu di ruangan tanpa jendela di lantai tiga, yang menurut Luana selalu patut dicurigai disengaja. Agenda hari ini hanya satu butir, dicetak tebal. Isinya menanyakan apakah peringkat triase rumah sakit, yang mengurutkan pasien yang menunggu di instalasi gawat darurat menurut prediksi risiko, boleh dikesampingkan oleh penilaian seorang perawat dan, bila boleh, dengan syarat apa. Luana, anggota awam komite sekaligus statistikawan pensiunan, sudah membaca laporan validasinya dua kali. Ia memercayai angka-angkanya. Yang belum ia percayai adalah kalimat "sistem ini benar pada sembilan puluh empat persen kasus".

The case that has forced the issue is described by the chair in careful, non-graphic terms. Three weeks ago a man in his sixties arrived with a vague discomfort in his chest and normal first readings, and the system placed him fourth in the queue. Toril, a senior nurse with twenty-six years on the floor, moved him to first, writing only "doesn't look right" in the notes. Within the hour he was found to need urgent treatment, and he is now recovering at home.

Kasus yang memaksa persoalan ini muncul diuraikan oleh ketua dengan istilah hati-hati dan tidak vulgar. Tiga minggu lalu seorang pria berusia enam puluhan datang dengan rasa tak nyaman samar di dada dan hasil pemeriksaan awal yang normal, dan sistem menempatkannya di urutan keempat dalam antrean. Toril, seorang perawat senior dengan dua puluh enam tahun pengalaman di lapangan, memindahkannya ke urutan pertama, hanya menulis "tampaknya ada yang tidak beres" di catatan. Dalam satu jam ia diketahui membutuhkan penanganan darurat, dan kini ia pulih di rumah.

Toril has been invited to speak, and she does so without notes. She cannot say exactly what she saw, she admits; perhaps the greyness around his mouth, perhaps the way he kept apologising for taking up a chair. "If I had waited for the number to change, I would have been waiting for the wrong thing," she says. A young doctor objects, politely. Nurses have been wrong too, he points out, and the system exists precisely because tired people see patterns that are not there.

Toril diundang berbicara, dan ia melakukannya tanpa catatan. Ia mengaku tak bisa mengatakan persis apa yang ia lihat; mungkin warna kelabu di sekitar mulutnya, mungkin caranya terus meminta maaf karena menempati sebuah kursi. "Kalau saya menunggu angkanya berubah, saya akan menunggu hal yang salah," katanya. Seorang dokter muda keberatan, dengan sopan. Perawat pun bisa keliru, ujarnya, dan sistem itu ada justru karena orang yang lelah melihat pola yang sebenarnya tidak ada.

Luana asks for the override log. There have been eighty-one in two years, and what strikes her, turning the pages, is that the nurses were right far more often than not, and wrong in a pattern. The overrides that proved unnecessary cluster among patients who were articulate, calm and easy to like. Had the system been left unchallenged, the man with the chest discomfort would have waited; had the nurses never been checked, the people who are easy to like would always have been seen first.

Luana meminta catatan penggantian peringkat. Ada delapan puluh satu dalam dua tahun, dan yang mengejutkannya, sambil membuka halaman demi halaman, adalah bahwa para perawat jauh lebih sering benar daripada salah, dan salahnya berpola. Penggantian yang ternyata tak perlu menggerombol pada pasien yang pandai bicara, tenang, dan mudah disukai. Seandainya sistem dibiarkan tanpa tantangan, pria dengan rasa tak nyaman di dada itu akan menunggu; seandainya para perawat tak pernah diperiksa, orang-orang yang mudah disukai akan selalu dilayani lebih dulu.

"Both of those are true," she hears herself say, to her own surprise, "and neither of them is an argument for choosing one."

"Keduanya benar," ia mendengar dirinya berkata, yang mengejutkannya sendiri, "dan tak satu pun merupakan argumen untuk memilih salah satunya."

Not until two hours have passed does the committee reach an answer, and it is neither a victory nor a compromise in the usual sense. Any nurse may override a ranking at once, without asking permission, but she must record one line of reasoning. The system, for its part, will display its own uncertainty beside every rank instead of hiding it behind a single tidy number. Each month the overrides will be reviewed by pattern rather than by person, and the algorithm's misses will be audited in the same meeting, at the same table.

Baru setelah dua jam berlalu komite mencapai jawaban, dan itu bukan kemenangan maupun kompromi dalam arti biasa. Setiap perawat boleh mengganti peringkat seketika, tanpa meminta izin, tetapi ia harus mencatat satu baris alasan. Sistem, di pihaknya, akan menampilkan ketidakpastiannya sendiri di samping setiap peringkat alih-alih menyembunyikannya di balik satu angka yang rapi. Setiap bulan penggantian itu akan ditinjau menurut pola, bukan menurut orang, dan kesalahan algoritma akan diaudit dalam rapat yang sama, di meja yang sama.

Toril reads the draft over Luana's shoulder. "One line of reasoning," she says. "I can do that. Most nights the reason is only a feeling."

Toril membaca rancangan itu dari balik bahu Luana. "Satu baris alasan," katanya. "Itu bisa saya lakukan. Kebanyakan malam alasannya hanya firasat."

"Write it down anyway," Luana says. "Then we can find out what the feeling was made of."

"Tetap tuliskan," kata Luana. "Supaya kita bisa mencari tahu firasat itu terbuat dari apa."

Toril nods slowly and asks whether there will be a place on the form for the nights she is wrong. Luana turns the page. There is already a box at the bottom, small and unremarkable, labelled "What I missed."

Toril mengangguk pelan dan bertanya apakah akan ada tempat di formulir untuk malam-malam ketika ia salah. Luana membalik halaman. Sudah ada sebuah kotak di bagian bawah, kecil dan tak mencolok, berlabel "Yang saya lewatkan."
