Quality Measure Dashboard

Overview

Calculate formal HEDIS and CMS quality measures using FHIR R4 data. Apply numerator/denominator/exclusion logic per measure specification. Report measure rates, compare against benchmarks, identify patients falling out of compliance, and track trends. Supports measures for diabetes care (A1c, eye exam, nephropathy), hypertension control, breast cancer screening, colorectal cancer screening, depression screening, statin therapy, and tobacco cessation. See references/hedis-measure-definitions.md for full specifications.

Instructions

Step 1: Select Measures to Calculate

Determine which measures the user wants. If unspecified, calculate the core set:

•HBD - Hemoglobin A1c Control for Patients with Diabetes (A1c < 8%)
•CBP - Controlling High Blood Pressure (BP < 140/90)
•BCS - Breast Cancer Screening (mammogram in 27 months)
•COL - Colorectal Cancer Screening (per USPSTF intervals)
•DSF - Depression Screening and Follow-Up
•SPD - Statin Therapy for Patients with Diabetes
•TCC - Tobacco Cessation Counseling

Step 2: Build Denominator Population

For each measure, query the eligible population per specification. See references/hedis-measure-definitions.md for detailed criteria.

HBD - Diabetes A1c Control:

code

Tool: fhir_search
resourceType: "Condition"
queryParams: "code=http://snomed.info/sct|44054006,http://snomed.info/sct|46635009&clinical-status=active&_count=200"

SNOMED 44054006 = Type 2 DM, 46635009 = Type 1 DM. Denominator = patients 18-75 with active diabetes.

CBP - Blood Pressure Control:

code

Tool: fhir_search
resourceType: "Condition"
queryParams: "code=http://snomed.info/sct|38341003&clinical-status=active&_count=200"

Denominator = patients 18-85 with active hypertension diagnosis.

BCS - Breast Cancer Screening:

code

Tool: fhir_search
resourceType: "Patient"
queryParams: "gender=female&birthdate=ge[73-years-ago]&birthdate=le[52-years-ago]&_count=200"

Denominator = females age 52-74.

Filter each denominator by age using Patient.birthDate.

Step 3: Apply Exclusions

For each measure, query and remove excluded patients.

HBD exclusions (hospice, ESRD):

code

Tool: fhir_search
resourceType: "Condition"
queryParams: "code=http://snomed.info/sct|46177005&clinical-status=active&_count=100"

SNOMED 46177005 = End-stage renal disease.

code

Tool: fhir_search
resourceType: "Encounter"
queryParams: "type=http://snomed.info/sct|385763009&date=ge[measurement-year-start]&_count=100"

SNOMED 385763009 = Hospice care.

BCS exclusions (bilateral mastectomy):

code

Tool: fhir_search
resourceType: "Procedure"
queryParams: "code=http://snomed.info/sct|27865001&_count=100"

SNOMED 27865001 = Bilateral mastectomy.

Remove excluded patients from the denominator.

Step 4: Calculate Numerator

Query evidence of compliance for denominator patients.

HBD numerator (A1c < 8%):

code

Tool: fhir_search
resourceType: "Observation"
queryParams: "code=http://loinc.org|4548-4&date=ge[measurement-year-start]&_sort=-date&_count=200"

LOINC 4548-4 = HbA1c. Take most recent per patient. Numerator = patients with A1c < 8.0%.

CBP numerator (BP < 140/90):

code

Tool: fhir_search
resourceType: "Observation"
queryParams: "code=http://loinc.org|85354-9&date=ge[measurement-year-start]&_sort=-date&_count=200"

LOINC 85354-9 = Blood pressure panel. Numerator = most recent systolic < 140 AND diastolic < 90.

BCS numerator (mammogram in 27 months):

code

Tool: fhir_search
resourceType: "DiagnosticReport"
queryParams: "code=http://loinc.org|24606-6&date=ge[27-months-ago]&_count=200"

LOINC 24606-6 = Breast screening mammogram. If no DiagnosticReport, try Procedure:

code

Tool: fhir_search
resourceType: "Procedure"
queryParams: "code=http://snomed.info/sct|71651007&date=ge[27-months-ago]&_count=200"

COL numerator:

code

Tool: fhir_search
resourceType: "Procedure"
queryParams: "code=http://snomed.info/sct|73761001&date=ge[10-years-ago]&_count=200"

SNOMED 73761001 = Colonoscopy (within 10 years). Also check FIT/FOBT within 1 year (LOINC 29771-3) and flexible sigmoidoscopy within 5 years (SNOMED 44441009).

Step 5: Compute Measure Rates

For each measure:

•Rate = Numerator / (Denominator - Exclusions) * 100
•Gap count = Denominator - Exclusions - Numerator
•Gap-to-goal = Target rate - Current rate

Use benchmarks from references/quality-reporting.md.

Step 6: Identify Non-Compliant Patients

For each measure, list patients in the denominator but NOT in the numerator (after exclusions). These are the "gaps in care."

Sort by:

•Measures with most gaps first
•Within each measure, patients with longest time since last compliant event

Step 7: Present Dashboard

Example 2: Single Measure Deep Dive

User says: "How are we doing on A1c control? Show me who's not at goal."

Actions:

•Query diabetes Conditions (active T1DM + T2DM). Returns 87 patients.
•Filter ages 18-75. Remove hospice/ESRD exclusions (3 excluded).
•Query A1c observations in measurement year. Take most recent per patient.
•Classify: < 7% (well controlled), 7-8% (at HEDIS goal), 8-9% (above goal), > 9% (poorly controlled), no data.

Result:

code

A1c CONTROL MEASURE - DEEP DIVE
================================
Denominator: 87 | Exclusions: 3 | Eligible: 84
Numerator (A1c < 8%): 68 | Rate: 81.0% | Target: 85.0%

A1c DISTRIBUTION
----------------
< 7.0% (well controlled):    52 (61.9%)
7.0-7.9% (at HEDIS goal):    16 (19.0%)
8.0-8.9% (above goal):        7 (8.3%)
>= 9.0% (poorly controlled):  5 (6.0%)
No A1c this year:              4 (4.8%)

NON-COMPLIANT PATIENTS (16):
1. Marcus Hall (MRN: 55102) - A1c: 11.8% (2024-03-15) - On metformin only - RECOMMEND: Add second agent
2. Nancy Chen (MRN: 44290) - A1c: 10.2% (2024-06-01) - On metformin + glipizide - RECOMMEND: Switch to GLP-1/SGLT2
3. Thomas Brown (MRN: 33871) - A1c: 9.6% (2024-08-20) - Not on any diabetes meds - RECOMMEND: Start therapy
4. Susan Park (MRN: 22150) - No A1c since 2023-09-01 - RECOMMEND: Order stat A1c
...

CLOSING THE GAP:
- 4 patients need A1c ordered (quick win)
- 5 patients with A1c > 9% need urgent therapy intensification
- 7 patients with A1c 8.0-8.9% need follow-up within 3 months

Troubleshooting

Measure denominator is unexpectedly small or zero

•The FHIR server may not use SNOMED codes. Try ICD-10: code=http://hl7.org/fhir/sid/icd-10-cm|E11 for diabetes, I10 for hypertension.
•Some servers require exact code match. For diabetes, also include: E11.0, E11.1, E11.2, etc. Use prefix matching if supported: code=http://hl7.org/fhir/sid/icd-10-cm|E11.
•Check that clinical-status is populated. Some systems leave it blank for active conditions.

DiagnosticReport not available for screening measures

•Not all FHIR servers expose DiagnosticReport. Fall back to Procedure searches for the screening event itself.
•Check if the server stores mammograms as Observation resources with imaging LOINC codes.
•For colonoscopy, also search Procedure with CPT code: code=http://www.ama-assn.org/go/cpt|45378.

Numerator count seems too low despite patients being treated

•Verify date range. HEDIS measurement year is typically calendar year. Ensure date=ge[year-start] covers the correct period.
•Some measures accept lookback beyond the measurement year (e.g., colonoscopy 10 years). Adjust date filter accordingly.
•Lab results may be stored with effectiveDateTime outside the search range if the specimen was collected near year boundaries.
