|---|---|---|---|---|---|---|---|---|---|---|
| 1 | lab catalog creation at the lab |
| N/A SM: LIS to everything else? or LIVD to LIS?
This are historic paper catalogs, but most labs now publish electronic version on websites, or have different file structures where they can be downloaded by customers (i.e. EHR for use in CPOE). However, much manual work per ONC/ACLA study/calculator: Highlighting a Way to Advance Interoperability and Reduce Costs for Lab Tests - Health IT Buzz | IVD vendor
| LIS | spreadsheet | SM: LOINC, units of measure, UDI, Traceability (RM: what data element is tracking this?), RM: Performed test name, test kit identifcation, instrument identifiation, all expected result values, all applicable units of measure, allowable specimen, ordered test name? | LIVD JSON / spreadsheet format | SOLOR / Terminology services LOINC search / RELMA IVD package inserts with info on each assay/aalyte/test | ARP: Is this creation of the CAP/CLIA Specimen Collection Manual, aka laboratory compendium, where each lab distinguishes tests on their menu or something else? If lab compendium, there are CLIA requirements, and eDOS (Electronic Directory of Service) in HL7 v2.51 format or Service Catalog in FHIR provide electronic specifications, but not yet widely adopted. |

|
|
| 12 | result use in provider setting | creating flow sheets | ?? Performing lab provides provider results in their EHR. At the doorstep, the lab result of record is preserved to show CMS/CLIA inspectors. HL7 message is remapped into EHR database and original message destroyed. Often performing lab naming conventions are “transformed” to EHR naming conventions. Data are presented to providers depending on EHR functionality/screen view (i.e. flow sheet, results review, graphs, tables, POV), all which may differ in how lab results/data are presented/utilized | Hospital |
|
|
|
|
| ARP: Is this only EHR flow sheets or does it include Problem Oriented View and other “results review” EHR functionality? see http://problemlist.org
|
| 13 | result use in research (FDA pre-market?) |

| 16 | Patient Performed Testing (home) | patient collected specimens sent to CLIA lab for drug screening, COVID, genetic/ancestry testing. Kits purchased online and delivered to pt or purchased in pharmacy/store. Unique identifier code for specimen container, is registered to patient email so they receive results. patient collects specimen and mails to vendor/lab. Lab results mailed, emailed back to patient. Public health reportables (i.e. std, covid testing) may not receive patient info (i.e. contact info/address, demographics, AOEs, age) |

|
| patient collected specimens sent to CLIA lab |
| 17 | Pathologist reporting | For pathology and cancer reporting, AJCC 8th edition/CAP eCC content is collected/reported on specimens per the different Cancer Protocols, including Biomarkers. | Pathologist generated report sent to EHR, and downstream hospital cancer registrar report sent to central cancer registrar reporting (may need to split these into separate use cases) |
| Anatomic Pathology and Laboratory Information Systems to EHRs | CAP eCC for cancer reports, APLIS pathology reports (non cancer) |
| LOINC, SNOMED CT, ICD-O3, other code systems (i.e. HUGO for genomics) |
| Clinical lab tests (i.e. PSA, WBC, CA125, BRCA, Her2, Neu, ER, PR, KRAS, other markers) mapped to LOINC codes in the clinical lab (using LIVD) should flow into the APLIS/path reports, which then should flow into cancer registry reports, mCODE (EHR), etc. and be all aligned on coding. Currently PSA LOINC encoded is entered in text and CAP eCC is being SCT encoded, NAACCR data elements also use LOINC so 3 steps of mapping/remapping/contributing to burdens/inoperability. |
| 18 | HHS/COVID reporting first part | LIS/lab reporting to public health jurisdiction (may overlap with ELR for labs, may not for pt reported results), WATERS connectathon systems, EHRs (cvs, walgreens), home grown systems, IVD vendor systems (i.e. lumira, abbott) | lis, app, ehr to public health | testing entity/ performing lab (traditional/nontraditional) , public health | LIS, EHR, Public Health systems, LIMS, |
| Results, AOEs, etc |
| ELR, Waters Connectathon solutions, APHL template | All original sources of COVID data/results, AOEs |

| 20 | Electronic Case Reporting (eCR) on e of the standards to use for use case #11 |
| MD EHR to CDC/Public Health | providers | EHR | EHR functionality, CDC FHIR app |
| HL7 ECR guide CDC FHIR app |
| Once this is more pervasive functionality, the extra items in ELR/HHS reporting can be moved to eCR where it is better suited. |
| 21 | Genomics/Molecular reporting | performing lab to EHR -oncology systems. performing lab to public health (where done on reportable condition, such as COVID variant sequencing, infectious diseases | performing lab to EHR -oncology systems (where mCODE used). performing lab to public health (where done on reportable condition, such as COVID variant sequencing), Cancer reporting/systems/cancer registries
| Performing labs, oncology systems, oncologists, | LIS/APLIS, EHRs, CG modules, |
|
| HL7 CG IG, mCODE (receiver/secondary system) |
| Mapping to LOINC/codesystems a bit different for genetic testing. Dr. Alexis Carter can add much more here too |
| 22 | Healthcare Associated Infection (HAI) Reporting | Hospital (EHR) to CDC NHSN. reporting. | EHR to CDC NHSN |
| Hospital (EHR) |
|
| HAI CDA IG |
| Note. remapping of post coordinated results from LIS to EHR occurs in EHR to support CDA IG needs. For example a VRE from LIS (to ELR and EHR) may be a vanc antibiotic mapped to LOINC, the resistant value mapped to SCT qualifier, and SCT org code mapped to Enterococcus faecalis, while HAI CDA requires precoordinated SCT organism code for Vancomycin Resistant Enterococcus to be sent (notice specific organism info lost). |
| 23 | Transfers of Care (TOC) = provider to provider | provider/facility EHR generates a transfer of care doc in CDA which includes LOINC encoded lab results, meds, etc. It is sent with patient when transferred to another (i.e. SNF, rehab, another hospital, long term care facility,) (If patient returns/readmitted, expect the opposite flow would occur from facility to hospital too) |
| hospitals, long tern care (LTC), Skilled Nursing facility (SNF), sub acute rehab hospital, etc. | EHR | some print a paper summary and tuck in the back of the patient’s wheelchair/bed when transferred by ambulance between the entities. Admitting nurse will type in data into receiving EHR system |
| TOC CDA (CCDA) IG |
|
|
| 24 | LIS reporting to HIE | Some labs report from their LIS to an HIE to exchange data with providers, or to send ELR to public health | LIS to HIE | labs, HIEs, providers, public health |
| variable |
|
|
| Some HIEs add LOINC, SCT codes, |
| 25 | Providers reporting lab results to HIEs | Some providers send EHR data to HIEs. Need to confirm, but I think some may order labs this way too. May also involve one provider’s patient results sent to another such as a specialist | EHR to HIE |
|
|
|
|
|
|
|
| 26 | Hospital Lab referral testing (orders) | Referral lab order requests from smaller hospital lab to large lab/academic medical center, public health lab, blood bank (ab testing) or reference lab |
|
|
|
|
|
| If set up electronically HL7 v2.x. some have web portals |
|
| 27 | Consumer performed lab tests (part 1a) | Test kit smartphone reader paired w vendor web portal to collect info form consumer. eventually reported back to pt via consumer portal/app below. |
|
|
|
|
|
|
| UA, Alb/CR, WBC, Neut% LOINCs needed for consumer/app results to distinguish those from health professional performed in EHR |
| 28 | Consumer collected/lab performed lab tests (aka Direct Access Testing, ) part 1b | Consumer collected/lab performed lab tests (aka Direct Access Testing,) | performing lab LIS- > Consumer web portal for results , app, or paper report |
|
|
|
|
|
| Is data discrete or pdf? Is data encoded? Home COVID-19 kits, 23 and me-genetic testing, etc.
|
| 29 | Consumer test results communicated to provider EHR (part 2) | Consumer web portal, scanned/uploaded reports into EHR patient portal, consumer app import into EHR, consumer device to EHR transmission etc |
|
|
|
|
|
|
| Monitoring of pt daily gluc levels w decision support to alert providers of issues or MD manual rvw.
ie.. how are cosumer performed covid tests integrated/received into EHR from home testing? EHRs don’t have capability to receive FHIR app results currently. |
