v1.0.0 · Open source · MIT

A REDCap instrument ready to import.

Pre-built data dictionary and XML instrument for the peer-reviewed HEARTLAND Protocol. Five forms, 75 variables, a weighted 0-18 risk score, and 12 monthly follow-ups — so any rural hospital or research institution can start collecting structured heart failure data on day one.

For clinicians and researchers with institutional REDCap access. All sample data is synthetic — no PHI is ever transmitted or collected by this template.

What's inside

Five forms, one shared workflow.

Clinical definitions match the published Protocol v3.3 exactly. Calculated fields, branching logic, and a 20-row synthetic sample dataset are all included so your first import validates cleanly.

  • 01

    Enrollment

    Facility information, consent, demographics, geographic context (state, county FIPS, USDA RUCA rurality).

  • 02

    Baseline

    The ten HEARTLAND risk variables and a weighted 0-18 score with automatic tier assignment (low / moderate / high).

  • 03

    GDMT Status

    RAS inhibitor, beta-blocker, MRA, and SGLT2i tracked with target doses, start dates, and the generic $4 bridge option.

  • 04

    Monthly follow-up

    Repeating instrument, months 1-12. Vitals, optional labs, GDMT titrations, red flags, hospitalizations, KCCQ-12.

  • 05

    12-month outcomes

    Mortality, HF hospitalizations, HF ED visits, days alive and out of hospital, and GDMT optimization rate.

Quickstart

Three steps, fifteen minutes.

REDCap 14.x or newer is recommended. A 13.x instance works with minor caveats documented in the import guide.

  1. 01

    Create an empty REDCap project

    In your institutional REDCap, pick New Project → Research → name it (e.g. “HEARTLAND Validation — Site X”).

  2. 02

    Upload the data dictionary

    Project Setup → Data Dictionary → Upload. Select heartland_data_dictionary.csv from the GitHub release.

  3. 03

    Enable the repeating instrument

    Project Setup → Enable optional modules → Repeatable instruments and events. Mark monthly_followup as repeating.

Clinical foundation

Every field traces back to the peer-reviewed protocol.

The data dictionary mirrors HEARTLAND Protocol v3.3 exactly. The codebook PDF cites the specific module or table for every variable, so reviewers and adjudicators can verify clinical fidelity without leaving the repo.

  • Protocol v3.3

    Ferreira VM. HEARTLAND Protocol: A Tiered Clinical Implementation Toolkit.

  • Risk score

    Weighted 0-18 points across ten variables, three tiers.

Suggested validation study

A reference design you can hand to your IRB.

A pre-written, STROBE-aligned observational protocol ships alongside the instrument. Primary endpoint, statistical plan, and inclusion criteria are ready to adapt — no blank page to fight on a Sunday night.
