Definition

START is a clinical decision support criteria set used in EHR systems to identify potentially appropriate medications for older adults, complementing the STOPP criteria. Data engineers encounter START codes in pharmacogenomics, medication management, and geriatric care management datasets within EHR and PBM platforms to support polypharmacy audits.

Standard Abbreviation

START

Database Usage

-- Example column naming
CREATE TABLE claims (
  clm_id VARCHAR(50),
  start VARCHAR(100),  -- Screening Tool to Alert to Right Treatment (max 100 chars)
  ...
);

-- Example in SELECT
SELECT
  clm_id,
  start as screening_tool_to_alert_to_right_treatment
FROM claims;

Example database column name

ISO-11179 snake_case standard

-- Recommended column name
start

-- Example DDL
CREATE TABLE healthcare_data (
  record_id   VARCHAR(50)   NOT NULL,
  start        VARCHAR(100),  -- Screening Tool to Alert to Right Treatment (max 100 chars)
  created_dt  TIMESTAMP     NOT NULL DEFAULT NOW()
);

Column names follow the ISO-11179 naming convention: lowercase, underscore-separated, using the standard abbreviation as a prefix where applicable.

Why This Term Matters

Clinical terms are the building blocks of risk adjustment, quality measurement, and value-based care analytics. A data engineer who understands this terminology can design schemas that correctly capture patient conditions, procedures, and encounters — enabling accurate HCC scoring, HEDIS measure attribution, and CMS reporting. Misclassifying clinical fields in a data warehouse cascades into incorrect RAF scores and failed regulatory submissions.

Common uses in healthcare data

Risk stratification and population health analytics
CMS-HCC risk adjustment and RAF score calculation
Quality measure attribution and HEDIS reporting
Clinical data warehouse schema design
Value-based care contract performance tracking
Epic MyChart and Cerner PowerChart clinical data extraction for analytics pipelines
Snowflake VARIANT column mapping for semi-structured HL7 FHIR clinical payloads
Databricks Delta Lake pipeline orchestration for longitudinal patient cohort analysis

Related Healthcare Standards

HL7 FHIR R4

Defines clinical resource models (Patient, Condition, Observation, Encounter) that map directly to clinical data warehouse schemas and interoperability pipelines.

ICD-10-CM / ICD-10-PCS

The diagnosis and procedure coding systems mandated for all clinical documentation and claims in the US healthcare system.

HEDIS (NCQA)

Specifies clinical quality measure definitions that determine how clinical data is collected, attributed, and reported for Stars and value-based care contracts.

Data Quality Considerations

ICD-10-CM codes are frequently entered with invalid trailing characters or missing decimal points — validate against the current CMS ICD code reference table before loading into your clinical data warehouse.
Clinical date fields (admit date, discharge date, procedure date) often arrive with timezone offsets stripped — standardize to UTC at ingestion and store as TIMESTAMP_NTZ in Snowflake or TIMESTAMP in Databricks.
Null vs. unknown must be distinguished in clinical data: a missing diagnosis code may mean 'not documented' rather than 'not applicable' — use explicit sentinel values and document the distinction in your data dictionary.
