Progress Note Writer

Overview

Generate structured daily inpatient progress notes by pulling 24-hour data windows from FHIR resources. Assemble vitals trends, intake and output, laboratory results, imaging results, medication changes, and overnight events into a problem-oriented format. Include standing order status for DVT prophylaxis, GI prophylaxis, diet, activity level, and code status. Flag critical values and significant changes from prior day.

FHIR Resources Used

Instructions

Step 1: Retrieve Encounter and Calculate Hospital Day

Tool: fhir_read
resourceType: "Encounter"
id: "[encounter-id]"

Calculate hospital day: (today - period.start) + 1. Extract admitting diagnosis from reasonCode.

If encounter ID unknown:

Tool: fhir_search
resourceType: "Encounter"
queryParams: "patient=[patient-id]&class=IMP&status=in-progress&_sort=-date&_count=1"

Step 2: Retrieve Patient Demographics

Tool: fhir_read
resourceType: "Patient"
id: "[patient-id]"

Step 3: Pull 24-Hour Vital Signs Trends

Define the 24-hour window: [today 00:00] to [now], or [yesterday same-time] to [now].

Tool: fhir_search
resourceType: "Observation"
queryParams: "patient=[patient-id]&category=vital-signs&date=ge[24h-ago]&_sort=date&_count=100"

Present as trends:

• Temperature: Tmax, Tcurrent (flag if Tmax >= 38.0 C / 100.4 F)
• Heart rate: Range (low-high), current
• Blood pressure: Range, current (flag if MAP < 65 or SBP > 180)
• Respiratory rate: Range, current
• SpO2: Range, current, oxygen delivery method if available
• Pain score (LOINC 72514-3): Most recent

Step 4: Pull Intake and Output

Tool: fhir_search
resourceType: "Observation"
queryParams: "patient=[patient-id]&code=http://loinc.org|9187-6&date=ge[24h-ago]"

LOINC codes for I&O:

• 9187-6: Fluid intake 24h
• 9192-6: Fluid output 24h
• Also search: code=http://loinc.org|9192-6

Calculate net fluid balance. Flag if net positive > 1L or net negative > 2L.

If I&O Observations not available, note: "I&O data not captured in structured FHIR observations -- obtain from nursing flowsheet."

Step 5: Pull Laboratory Results (24h)

Tool: fhir_search
resourceType: "Observation"
queryParams: "patient=[patient-id]&category=laboratory&date=ge[24h-ago]&_sort=-date&_count=50"

Group by panel. For each result:

• Compare to prior value if available (trend direction)
• Flag abnormal values with reference range
• Highlight critical values (e.g., K < 3.0 or > 6.0, Na < 125 or > 155, Hgb < 7, platelets < 50k, lactate > 4)

Step 6: Pull Imaging and Diagnostic Reports (24h)

Tool: fhir_search
resourceType: "DiagnosticReport"
queryParams: "patient=[patient-id]&date=ge[24h-ago]&_sort=-date"

Extract conclusion or presentedForm text. If results reference Observation resources in result, follow references with fhir_read.

Step 7: Pull Active Medications and 24h Changes

7a: Current active orders

Tool: fhir_search
resourceType: "MedicationRequest"
queryParams: "patient=[patient-id]&status=active&_count=100"

7b: Medications administered in 24h

Tool: fhir_search
resourceType: "MedicationAdministration"
queryParams: "patient=[patient-id]&effective-time=ge[24h-ago]&_count=100"

Identify:

• New medications started in 24h (authoredOn within window)
• Dose changes
• Discontinued medications (status=stopped with authoredOn in window)
• PRN medications administered with frequency

Step 8: Pull Procedures Performed in 24h

Tool: fhir_search
resourceType: "Procedure"
queryParams: "patient=[patient-id]&date=ge[24h-ago]"

Step 9: Pull Active Problem List

Tool: fhir_search
resourceType: "Condition"
queryParams: "patient=[patient-id]&clinical-status=active"

Step 10: Check Standing Orders and Prophylaxis

Search for prophylaxis orders:

DVT prophylaxis:

Tool: fhir_search
resourceType: "MedicationRequest"
queryParams: "patient=[patient-id]&status=active&code=http://www.nlm.nih.gov/research/umls/rxnorm|67108"

RxNorm 67108 = enoxaparin. Also check: 11289 (heparin).

GI prophylaxis:

Tool: fhir_search
resourceType: "MedicationRequest"
queryParams: "patient=[patient-id]&status=active&code=http://www.nlm.nih.gov/research/umls/rxnorm|40790"

RxNorm 40790 = pantoprazole. Also check: 29046 (famotidine).

If prophylaxis not found, flag as gap.

Diet and activity: Check CarePlan resources:

Tool: fhir_search
resourceType: "CarePlan"
queryParams: "patient=[patient-id]&status=active&category=http://hl7.org/fhir/us/core/CodeSystem/careplan-category|assess-plan"

Troubleshooting

MedicationAdministration not available on the FHIR server

• This resource is optional in many FHIR implementations. Rely on MedicationRequest with status=active for the medication list.
• Note in the progress note that administered medication data could not be verified. PRN usage will need to be obtained from nursing documentation.
• Check if the encounter-level medication list is available through a different resource type.

I&O data not captured in FHIR Observations

• Intake/output is frequently not stored as discrete FHIR Observations. It may exist only in nursing flowsheets within the EHR.
• Flag as: "I&O: Not available in structured FHIR data -- obtain from nursing flowsheet."
• Do not fabricate I&O values. The note should explicitly state data is unavailable.

DiagnosticReport returns references but no conclusion text

• Follow DiagnosticReport.result references to individual Observation resources using fhir_read.
• Check DiagnosticReport.presentedForm for full text attachments.
• If neither is available, note: "[Study type] performed [date] -- result pending or not available in structured data."
