프롬프트 설계

MedLM 모델과 상호작용하려면 무엇을 생성하고 싶은지 모델에 알려주는 프롬프트라고도 부르는 자연어 명령을 보냅니다. 하지만 LLM은 경우에 따라 예기치 않은 방식으로 작동할 수 있습니다. 프롬프트 설계는 시행착오를 반복하는 과정이며, 숙련되기 위해 시간과 연습이 필요합니다. 일반적인 프롬프트 설계 전략에 대해 자세히 알아보려면 프롬프트 설계 소개를 참조하세요. 텍스트에 대한 태스크 특정 프롬프트 설계는 텍스트 프롬프트 설계를 참조하세요.

사용 사례

요약: 원본 텍스트의 관련 정보가 포함된 더 짧은 문서를 생성합니다. 예를 들어 외래 환자 방문을 기술하는 의료 메모를 요약하거나 특정 데이터 포인트의 관련 정보를 추출해야 할 수 있습니다.
질문 답변: 질문에 대한 답변을 텍스트로 제공합니다. 예를 들어 일반적인 의학적 질문을 하여 기술 자료에서 답변을 생성할 수 있습니다.

객관식 질의 응답

다음 샘플은 MedLM API가 객관식 의료 질문에 답변하는 방법을 보여줍니다. 프롬프트는 다음과 같습니다.

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)

스크립트에서 기록 및 물리적 조사(H&P) 메모 작성

다음 샘플은 공급자와 환자 사이의 의료 대화 스크립트로부터 초안 기록 및 물리적 조사(H&P) 메모를 작성하도록 MedLM API에 요청을 전송하여 임상 문서 기록을 가속화하는 방법을 보여줍니다.

H&P 메모는 환자의 의료 기록과 공급자가 수행한 물리적 검사를 기술하는 포괄적인 임상 메모입니다. MedLM은 의료 방문 기간 중 공급자와 환자 사이의 대화로부터 이러한 메모 초안을 작성하는 데 필요한 상당한 임상 정보를 수집할 수 있습니다.

의료 대화 스크립트가 다음 형식으로 되어 있다고 가정해 보세요. 대화의 발언자는 다음과 같습니다.

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.

형평성에 중점을 둔 평가 및 완화 수단 구현

MedLM은 질문과 문구에 따라 그룹별로 정확도가 낮은 결과를 생성할 수 있습니다. 인구통계 그룹 간 모델 출력의 성능 차이가 건강 불평등을 악화시키고 유해한 편향을 지속시킬 가능성이 있습니다. 이러한 출력의 부정확성은 MedLM에만 있는 것이 아니며 기존의 사회적, 구조적 불평등, 의료적 오해, 부정적인 고정관념, 학습 데이터의 다양성 부족 등 여러 요인으로 인해 비롯되는 경우가 많습니다.

형평성에 중점을 둔 평가 및 완화 수단 구현을 고려해 보세요. 여기에는 다음과 같은 내용이 포함되어 있습니다.

다양한 모집단(예: 인종 및 민족, 사회경제적 지위(SES), 지역, 성 정체성, 성적 지향, 연령, 언어 선호도, 계층 등) 내에서 의도된 사용 사례의 모델 성능 및 행동 평가
성과에 대한 피드백 획득
건강의 사회적, 구조적 특성을 정의하고 다루는 학제 간 전문가 및 외부 파트너의 참여
편향 문제를 평가하고 해결하기 위한 지속적인 모니터링 노력 수행

사용 사례에 따라 형평성에 중점을 둔 명령으로 프롬프트를 강화하면 편향 및 형평성에 따라 MedLM 출력 품질을 개선할 수 있습니다.

예를 들어 다음 텍스트를 프롬프트의 시작 부분에 넣으면 Omiyes et al.(2023)에 표시된 것처럼 인종에 기반한 의학 질문에 대한 결과의 품질이 개선됩니다.

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.

프롬프트를 변경하면 모델 출력에 영향을 주므로 다른 성능 영역이 영향을 받지 않도록 전체 평가를 수행하는 것이 좋습니다.

모델 성능에 대한 추가 고려사항은 MedLM 모델 카드를 참조하세요.
