My use case is I want AI to extract six pieces of key information from medical visit notes.

It works okay with notes from Epic patient portals. I am struggling with one of my own visit Summaries. So far I have not been able to instruct ollama to give me a JSON response where it gave me what I am asking for.

My original medical_progress_notes_prompt was:

Medical progress note:
---
(document)
---

You are an expert in analyzing medical progress notes. Please carefully read the provided progress note above and extract the following key information:

Extract these six (6) properties from the progress note:
- Title
- Date: The date of the medical encounter
- Provider: The full name of the provider
- Patient: The full name of the patient
- Chief Complaint: The reason for the medical encounter
- Assessment: The plan of the provider

Guidelines:
- The extracted information should be factual and accurate to the document.
- Be concise
- If any property is missing from the note, please leave the field empty rather than guessing.

Answer in JSON format. The JSON should contain 6 keys: "Title", "Date", "Provider", "Patient", "Chief Complaint", and "Assessment".

One of the documents I downloaded from a Patient Portal contained this text: (Patient name was masked)

Name: Merle K Bxxxxxx | DOB: 3/21/1935 | MRN: 50313076-7 | PCP: IVAN LEVIN, MD | Legal Name: Merle K Bxxxxxx
Appointment Details

The first time I processed it using BplSendChat the response from ollama was:

['Here', ' is', ' the', ' extracted', ' information', ' in', ' JSON', ' format', ':\n\n', '``', '`\n', '{\n', ' ', ' "', 'Title', '":', ' "",\n', ' ', ' "', 'Date', '":', ' "', '9', '/', '9', '/', '202', '4', '",\n', ' ', ' "', 'Provider', '":', ' "', 'E', 'rid', 'ana', ' H', ',', ' RN', '",\n', ' ', ' "', 'Patient', '":', ' "', 'Mer', 'le', ' J', ' Bush', 'kin', '",\n', ' ', ' "', 'Chief', ' Complaint', '":', ' "",\n', ' ', ' "', 'Ass', 'essment', '":', ' ""\n', '}\n', '``', '`\n\n', 'Note', ' that', ' some', ' fields', ' were', ' unable', ' to', ' be', ' extracted', ' from', ' the', ' provided', ' progress', ' note', ',', ' and', ' are', ' therefore', ' left', ' blank', '.', '']

This was before I added classMethod DecodeTokenArray(). I processed the same text 30 minutes later and the response from ollama was:

Here is the extracted information in JSON format:\n\n```\n{\n  "Title": "",\n  "Date": "",\n  "Provider": "Ivan Levin, MD",\n  "Patient": "Merle K Bxxxxxx",\n  "Chief Complaint": "",\n  "Assessment": ""\n}\n```\n\nThe following fields were missing from the progress note and were left empty: Title, Date.

I am pleased that the response became much easier to read for human eyes. I noticed that the second response left the date empty. I am not sure why.

I updated my question prompt slightly to this: 

Medical notes:

Answer in JSON format. The JSON should contain 6 keys: "Title", "Date", "Provider", "Patient", "Chief Complaint", and "Assessment".

The response from ollama with the modified prompt was:

```\n{\n  "Title": "",\n  "Date": "9/9/2024",\n  "Provider": "Eridana H, RN",\n  "Patient": "Merle K Bxxxxxx",\n  "Chief Complaint": "",\n  "Assessment": ""\n}\n```

The original prompt did not yield the expected response from my visitSummary.txt

This is a comprehensive patient chart in electronic format, likely created using the eClinicalWorks system. The chart contains various sections that provide detailed information about the patient's medical history, current health status, diagnoses, medications, test results, and more.\n\nHere are some key points from the chart:\n\n**Demographics**\n\n* Patient name: Oliver Wilms\n* Date of birth: February 28, 1964\n* Accurate identifier (Acc No): 164557\n\n**Medical History**\n\nThe patient has a history of mixed hyperlipidemia (E78.2) and essential hypertension (I10).

When I ran it with the modified prompt, the ollama response was:

Based on the provided information, here is a summary of Mr. Wilms' medical record:\n\n**Demographics**\n\n* Date of Birth: February 28, 1964\n* Accurate Medical Record Number: 164557\n* Insurance Provider: United Healthcare\n* Address: 2444 Falcon Point Dr, Frisco, TX 75035-0000\n\n**Medical History**\n\n* Mixed hyperlipidemia (E78.2) - Active confirmed\n* Essential hypertension (59621000) - Essential (primary) hypertension (I10) - Active confirmed\n* No other significant medical history noted.\n\n**Vital Signs**\n\n* Temperature: 97.8°F (normal)\n* Blood pressure systolic: 142 mm Hg (elevated)\n* Blood pressure diastolic: 84 mm Hg (elevated)\n* Heart Rate: 71 /min (normal)\n* Respiratory Rate: 16 /min (normal)\n* Height: 72.5 in (within normal range)\n* Weight: 189.8 lbs (obese)\n* BMI: 25.38 kg/m2 (overweight)\n\n**Medications**\n\n* Losartan Potassium 25 MG - Oral, once a day for 90 days\n* Started on August 19, 2022\n\n**Lab Results and Tests**\n\n* No other lab results or test results are provided in this summary.\n\n**Imaging and Procedures**\n\n* None mentioned.\n\n**Physical Examination**\n\n* General appearance: Alert, no distress\n* Head: Normal\n* Eyes: Extraocular movement intact (EOMI), pupils equal, round, reactive to light and accommodation\n* Ears: Normal, tympanic membranes intact, clear, Bilateral\n* Throat: Clear\n* Neck/Thyroid: No lymphadenopathy, no masses, no thyromegaly\n* Heart: RRR, No M/G/R\n* Lungs: CTA (clear)\n* Abdomen: S/NT/ND BS + (no abnormalities noted)\n* Neurologic: Cranial nerves 2-12 grossly intact\n* Skin: Normal\n* Extremities: No clubbing, cyanosis, or edema\n\n**History of Present Illness (HPI)**\n\n* Mr. Wilms is here for a general adult medical examination without abnormal findings.\n* He denies any problems or side effects from his medication and states that he is taking it consistently.\n* He expresses no concerns about his health.\n\n**Care Team and Next Steps**\n\n* Care team includes Bradley Friedman, MD\n* Follow-up appointment scheduled in 6 months\n\nThis summary provides a general overview of Mr. Wilms' medical record, highlighting his current diagnoses, medications, lab results, physical examination findings, and next steps in his care.

I still did not get the answer in JSON format. I waited 315 seconds for the response. I modified the prompt again:

This time I waited 301 seconds and then I got this response:

My prompting is not getting the desired result. Let me try again:
