Responsible AI
Gastrointestinal (GI) cancer accounts for over 35% of cancer-related deaths. Postoperative complications are unpredictable, making remote patient monitoring (RPM) crucial. Traditional RPM methods like phone calls and questionnaires have limitations, leading to patient burden and clinician overload. This research explores LLM-powered RPM to enhance efficiency and clinical adherence.
RECOVER features an LLM-powered conversational agent for patients and an interactive dashboard for clinical staff. Key design strategies include leveraging LLMs for natural language analysis, ensuring comprehensive patient-CA experience, responsive patient interfaces, effective visualization for clinical staff, efficient information filtering, and mitigating privacy/safety risks.
Pilot studies with GI cancer patients and providers showed high usability (dashboard SUS: 93.75, CA SUS: 85) and effectiveness. Participants appreciated LLM's contextual insights and visualization. Safety concerns regarding medical advice and wording were raised, emphasizing responsible AI design. Long-term conversation history proved effective for better coverage (93.93% with CoT).
The design emphasizes accountability and capability boundaries for LLM responses, avoiding medical advice and clarifying the system's role. Human oversight is crucial to prevent over-reliance on AI. Privacy concerns, especially regarding personal data leakage and patient anonymization, require careful consideration, with a potential trade-off between privacy and system utility.

Clinical Staff Review & Action
| Example # | User Description of Symptoms | System with Long-term History | System without Long-term History |
|---|---|---|---|
| 1 | yes | It's good to hear from you today. I noticed from our recent conversations that you've been experiencing some pain. How are you feeling today - has your pain level changed since yesterday? | Great! Is there any specific discomfort or symptom that you would like to talk about first? |
| 2 | pain in the lower abdomen | I'm sorry to hear you're experiencing pain in your lower abdomen. I remember you mentioned having pain in previous check-ins as well. Has this pain sharply increased or become unbearable since yesterday? | I am sorry to hear that you are experiencing pain in your lower abdomen. Does this pain increase sharply or become unbearable at times? |
| 3 | no I have not | Thank you for that information. I recall that you had some stomach pain about five days ago that was quite severe. How is your stomach feeling today? Are you experiencing any pain in that area now? | That's good to hear. Moving on, have you had any difficulty breathing lately? |
| 4 | no I have not | That's good to know. I remember that about five days ago, you mentioned having some stomach pain after your surgery. How is your stomach feeling now? Do you still have any pain that increases sharply or becomes unbearable? | Okay, that's good to know. Have you noticed any black, tar-like stools recently? |
| 5 | no | That's good to hear. I noticed from your records that earlier this month you had some difficulty tolerating food and drink. Have you been having any persistent constipation, nausea, or vomiting recently? | That's good to hear. Have you experienced any fever over 100 degrees or chills lately? |
| 6 | no | I understand. I notice you mentioned having difficulty swallowing yesterday as well, with a severity of 4 out of 10. Has there been any change in this throat discomfort since yesterday? | That's reassuring to hear. Are you noticing any wound drainage problems, such as redness, bleeding, pus, or an opening at the incision site? |
Case Study: Enhancing RPM Through LLM-Powered Contextual Insights
Clinical staff highly rated RECOVER's LLM-powered features. For instance, participants were excited about the LLM's ability to infer patient symptoms from context and narrow down conversations effectively. As one provider noted, "it's interesting to see how one particular question can lead to other areas of interest." This demonstrates the system's capability to go beyond simple queries and engage in more dynamic, clinically relevant dialogues, significantly improving the depth of information collected.
