How this service works
Peterson 2010 GWTG-HF Figure 2 integer points for in-hospital mortality in hospitalized heart failure: age 0-28, systolic BP 0-28, BUN 0-28, sodium 0-4, heart rate 0-8, COPD +2, caller-assigned nonblack (black=false) +3. Total 0-100. magent does not assign race. Not a diagnosis.
Output
Returns the GWTG-HF integer point total (0–100) composed of age points (0–28), systolic BP points (0–28), BUN points (0–28), sodium points (0–4), heart rate points (0–8), COPD bonus (+2 if true), and nonblack race bonus (+3 if black=false). Higher scores indicate greater predicted in-hospital mortality risk. Not a diagnosis.
Example use cases
ED triage risk stratification for HF
“This patient was just admitted to the ED with acute decompensated heart failure — age 65, systolic BP 130 mmHg, BUN 25 mg/dL, sodium 138 mmol/L, heart rate 92 bpm, no COPD, caller-assigned nonblack. What is their GWTG-HF in-hospital mortality score?”
ICU admission decision support
“We have an elderly 84-year-old heart failure patient in the ICU, systolic BP of 88 mmHg, BUN of 55 mg/dL, serum sodium 131 mmol/L, heart rate 100 bpm, with COPD, caller-assigned nonblack. Can you give me the Peterson 2010 GWTG-HF mortality integer score?”
Cardiology ward prognostic documentation
“For my heart failure patient, age 58, systolic blood pressure 160 mmHg, BUN 18 mg/dL, sodium 140 mmol/L, heart rate 76 bpm, no COPD, caller-assigned black — what is the GWTG-HF score per Peterson 2010?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/gwtg_hfWhen to prefer
Use this endpoint when you need the standardized Peterson 2010 GWTG-HF integer point score for an admitted heart failure patient, particularly when integrating a validated clinical risk tool into an automated clinical decision support workflow. Prefer this over ad-hoc risk estimates when you need a reproducible, published scoring system. Note that the caller must supply all clinical values (BUN, sodium, BP, etc.) — this endpoint does not retrieve lab values or diagnose conditions.
Side effects
- Missing required query parameters (age, sbp_mm_hg, bun_mg_dl, sodium_mmol_l, heart_rate_bpm, copd, black) returns validation error
- Out-of-range integers (e.g. age <18 or >120, BUN >200) may return error or clamped result
- Non-integer values passed for integer fields cause schema validation failure
- Payment failure (x402) if USDC not provided or insufficient balance
- Network timeout if the service is temporarily unavailable
