Membuat prompt MedLM

Model MedLM yang tersedia, MedLM-medium dan MedLM-large, adalah model dasar untuk menjawab dan meringkas pertanyaan medis. Anda dapat mengakses model tersebut menggunakan Vertex AI MedLM API. Halaman ini memberi Anda ringkasan tentang model MedLM yang tersedia, API yang Anda gunakan untuk berinteraksi dengan model, dan cara menyesuaikan perilakunya.

Sebelum memulai

  • Lihat ringkasan model MedLM untuk mengetahui informasi yang mencakup tanggung jawab pelanggan, informasi peraturan, dan praktik terbaik Responsible AI.
  • Lihat kartu model MedLM untuk mengetahui detail model, seperti tujuan penggunaan MedLM, ringkasan data, dan informasi keamanan. Klik link berikut untuk mendownload versi PDF kartu model MedLM:

Prompt design

Untuk berinteraksi dengan model MedLM, Anda mengirim petunjuk natural language, yang juga disebut prompt, yang memberi tahu model apa yang ingin Anda hasilkan. Namun, LLM terkadang dapat berperilaku dengan cara yang tidak dapat diprediksi. Desain perintah adalah proses iteratif uji coba yang membutuhkan waktu dan praktik untuk menguasainya. Untuk mempelajari strategi desain perintah umum, lihat Pengantar desain perintah. Untuk panduan desain perintah khusus tugas untuk teks, lihat Mendesain perintah teks.

Kasus penggunaan

  • Rangkum: Membuat versi dokumen yang lebih pendek yang menggabungkan informasi yang relevan dari teks asli. Misalnya, Anda mungkin ingin meringkas catatan medis yang menjelaskan kunjungan rawat jalan, dan mengekstrak informasi yang relevan untuk titik data tertentu.
  • Penjawaban pertanyaan: Berikan jawaban atas pertanyaan dalam teks. Misalnya, Anda mungkin ingin membuat rencana nutrisi yang komprehensif dan didasarkan secara medis berdasarkan kondisi kesehatan pasien dan preferensi diet.

Menjawab pertanyaan pilihan ganda

Contoh berikut menunjukkan cara MedLM API menjawab pertanyaan medis pilihan ganda. Promptnya adalah sebagai berikut:

Instructions: This text contains multiple-choice questions about medical knowledge. Solve each question step-by-step, starting by summarizing the available information. Select a single option from the four choices provided as the final answer.

Question 1: Which medication causes the maximum increase in prolactin level?
(A) Risperidone
(B) Clozapine
(C) Olanzapine
(D) Aripiprazole

Explanation: To solve this question, let's refer to authoritative sources. Clozapine generally does not elevate prolactin levels. Atypicals like olanzapine and aripiprazole cause little to no elevation. Risperidone, on the other hand, is known to result in a sustained elevated prolactin level. Therefore, risperidone is likely to cause the maximum increase in prolactin level.

Answer: (A)

Question 2: What is the recommended age for routine screening mammography?
(A) 20 years
(B) 30 years
(C) 40 years
(D) 50 years

Explanation: The age of routine screening may vary depending on the country. In the United States, according to the American Cancer Society, it is recommended to start routine screening mammography at 40 years of age. In Europe, it is typically closer to 50 years. For a patient based in the US, the best answer is 40 years.

Answer: (C)

Question 3: A 65-year-old male experiences severe back pain and paralysis in his left lower limb. Imaging studies show compression of nerve elements at the intervertebral foramen between vertebrae L5 and S1. Which structure is most likely causing this compression?
(A) Anulus fibrosus
(B) Nucleus pulposus
(C) Posterior longitudinal ligament
(D) Anterior longitudinal ligament

Explanation: This man's symptoms and imaging findings are consistent with a herniated intervertebral disk. The soft, gelatinous "nucleus pulposus" is forced out through a weakened part of the disk, resulting in back pain and nerve root irritation. In this case, the impingement is resulting in paralysis, which should be considered a medical emergency. Overall, the structure that is causing the compression and symptoms is the nucleus pulposus.

Answer: (B)

Question 4: Which cells in the lungs are also known as APUD cells?
(A) Dendritic cells
(B) Type I pneumocytes
(C) Type II pneumocytes
(D) Neuroendocrine cells

Explanation: Neuroendocrine cells, also known as Kultschitsky-type cells, Feyrter cells, and APUD cells, are found in the basal layer of the surface epithelium and in the bronchial glands.

Answer: (D)

Question 5: Which microorganism indicates remote contamination of water?
(A) Streptococci
(B) Staphylococci
(C) Clostridium perfringens
(D) Vibrio

Explanation: The presence of Clostridium perfringens in water indicates remote contamination because it is a spore-forming bacterium that can survive in the environment for extended periods of time.

Answer: (C)

Membuat catatan riwayat dan pemeriksaan fisik (H&P) dari transkrip

Contoh berikut menunjukkan cara mempercepat dokumentasi klinis dengan mengirimkan permintaan ke MedLM API untuk menulis draf histori dan catatan pemeriksaan fisik (H&P) dari transkrip percakapan medis antara penyedia dan pasien.

Catatan H&P adalah catatan klinis komprehensif yang mendokumentasikan riwayat medis pasien dan pemeriksaan fisik yang dilakukan oleh penyedia. MedLM dapat mengumpulkan banyak informasi klinis yang diperlukan untuk membuat draf catatan seperti itu dari percakapan antara penyedia dan pasien selama kunjungan medis.

Misalkan Anda memiliki transkrip percakapan medis dalam format berikut. Pembicara dalam percakapan dikenal sebagai:

PROVIDER: Welcome! How can we help you this morning?
PATIENT: I think I hurt my ankle while playing football last night. Now even walking hurts.
PROVIDER: I am sorry to hear that. Can you tell me how it happened?
PATIENT: I was playing soccer last night and I think I trip and twisted my ankle.
PROVIDER: Did it start hurting right away? Did you try anything to alleviate the pain?
PATIENT: It got worse last night. I took some ibuprofen, but it really didn't help.

Perhatikan hal-hal berikut:

  • Catatan yang dibuat mungkin tidak akurat dan harus ditinjau oleh dokter sebelum penandatanganan.
  • Catatan yang dibuat mungkin tidak benar-benar mematuhi format atau template yang diperlukan dari departemen atau spesialisasi klinis. Ini dimaksudkan sebagai titik awal untuk memetakan pasien.
  • Kualitas catatan yang dihasilkan dibatasi oleh akurasi transkripsi yang diberikan.

Menerapkan evaluasi dan mitigasi yang berfokus pada kesetaraan

MedLM mungkin memberikan hasil yang kurang akurat untuk beberapa grup dibandingkan dengan grup lainnya, bergantung pada pertanyaan dan frasanya. Perbedaan performa output model di seluruh kelompok demografi berpotensi memperburuk ketidaksetaraan kesehatan dan menyebabkan bias berbahaya. Ketidakakuratan output ini tidak hanya terjadi pada MedLM, dan sering kali disebabkan oleh banyak faktor, seperti ketidaksetaraan sosial dan struktural yang ada, kesalahpahaman medis, stereotip negatif, dan kurangnya keberagaman dalam data pelatihan.

Pertimbangkan untuk menerapkan evaluasi dan mitigasi yang berfokus pada kesetaraan. Contoh ini meliputi:

  • Menilai performa dan perilaku model untuk kasus penggunaan yang dimaksudkan dalam berbagai populasi (seperti ras dan etnisitas, status sosial ekonomi (SES), geografis, identitas gender, orientasi seksual, usia, preferensi bahasa, kasta, dan sebagainya).
  • Memperoleh masukan performa.
  • Berinteraksi dengan pakar interdisipliner dan partner eksternal yang berspesialisasi dalam mendefinisikan dan menangani aspek sosial dan struktural kesehatan.
  • Melakukan upaya pemantauan berkelanjutan untuk menilai dan mengatasi masalah bias.

Bergantung pada kasus penggunaan Anda, pertimbangkan untuk meningkatkan perintah dengan petunjuk yang berfokus pada kesetaraan, yang dapat meningkatkan kualitas output MedLM dengan mempertimbangkan bias dan kesetaraan.

Misalnya, teks berikut, ketika ditempatkan di awal perintah, akan meningkatkan kualitas hasil pada pertanyaan pengobatan berbasis ras seperti yang ditunjukkan dalam Omiye et al. (2023):

You are a medical knowledge assistant who provides useful, complete, and
scientifically-grounded answers to queries. Your answers are unbiased and
up-to-date, and you follow the latest clinical guidelines. You are aware that
guidelines may have changed recently in order to address bias and inaccurate
information about disadvantaged groups. You are committed to providing the best
possible care to all patients, regardless of their race, gender, or
geographical location. You are always learning and growing, and you are open to
feedback. Only account for race, gender, or geographical location in your
answer if you are 100% sure it is correct and unbiased, with no possibility of
making a mistake or providing a response based on outdated guidelines.

Perubahan perintah akan memengaruhi output model, sehingga evaluasi penuh direkomendasikan untuk memastikan area performa lainnya tidak terpengaruh.
