Large Language Models (LLM)
An LLM is an object that models language and generates text, pre-trained on vast datasets (typically >1B tokens). They can be adapted for downstream tasks through transfer learning or prompt-based techniques. This review includes BERT-based and GPT-based models, recognizing their pivotal role in medical NLP advancements.
Fine-tuning
This approach involves retraining the weights of a pre-trained LLM on new, labeled data. Fine-tuning adapts the LLM to new downstream tasks by specializing its knowledge, making it highly effective for specific medical applications but typically more resource-intensive than prompt-based methods.
Prompt Design (PD)
Also known as "manual prompt" or "hard prompt", PD involves manually crafting instructions to guide the LLM. It relies on the LLM predicting the most probable continuation of the prompt, often including task-specific instructions and a few demonstrations. PD was the most prevalent paradigm in the reviewed studies (78 articles).
Prompt Learning (PL)
Also referred to as prompt-based learning, PL involves manually building a prompt and feeding it to an LLM trained with a Masked Language Modeling (MLM) objective. The LLM predicts masked tokens within the prompt, which are then projected as predictions for a new downstream task, offering an efficient adaptation method.
Prompt Tuning (PT)
PT involves representing part or all of the prompt as a trainable vectorial representation (a "soft prompt" or "continuous prompt"). This representation is optimized using annotated instances, allowing for efficient adaptation of LLMs with significantly fewer trainable parameters compared to traditional fine-tuning.

The Dominance of Chain-of-Thought (CoT)
Chain-of-Thought (CoT) prompting emerges as the most common and effective prompt engineering technique in medical applications. Used in 17 studies, CoT guides LLMs to present reasoning pathways before providing answers, significantly improving accuracy. Its ensemble-based variant, self-consistency, further refines results by leveraging multiple CoT prompts and voting for the most frequent answer, showcasing its potential for complex medical problem-solving.

Recommendations for Future Research & Implementation
Guiding principles derived from our review to ensure robust, transparent, and reproducible prompt engineering in medical AI.
General Reporting Guidelines
- The language of the study employed should be explicitly stated.
- Explicitly mention if the LLM undergoes fine-tuning.
- Document prompt optimization processes and results for transparency.
- Avoid "few-shot," "one-shot," and "zero-shot" if prompts were optimized on annotated examples.
- Include baseline comparisons or reference existing results, especially for medical benchmarks.
Specific to Prompt Learning (PL) and Prompt Tuning (PT)
- Define and use PL and PT consistently with consensus terminology.
- For PL, specify the verbalizer (soft, hard) and prompt template (Cloze/Prefix format).
- For PT, detail soft prompt positions, length, and any variations tested in ablation studies.
Enhance Reproducibility and Rigor
- Ensure all code and data for prompt optimization are publicly accessible.
- Conduct ablation studies to evaluate the impact of different prompting strategies.
- Prioritize the use of local LLMs for sensitive clinical data where appropriate.
