Timely discharge prediction is important for surgical unit operations. Using 3,928 postoperative patient notes (32.2% positive), we compared TF-IDF models, sentence embeddings, and LoRA-fine-tuned small language models (SLMs). TF-IDF with LightGBM performed best (F11 = 0.47, AUC = 0.80), while embeddings and SLMs showed limited sensitivity, with only modest recall gains from LoRA. Overall, lightweight and interpretable text models outperformed transformer-based approaches in this imbalanced next-day discharge prediction task.
