Calculators

Renal function for drug dosing. Both equations always compute. Result pushes to Drugs session context so the next drug lookup is renal-adjusted automatically.

8-element bedside deterioration score. Scale 1 + Scale 2 (COPD/Type-2 RF). Auto-banner amber at ≥5, red at ≥7.

Winters' / compensation, anion gap (with albumin correction), delta-delta, P/F + A-a. qwen 14b synthesizes the ranked differential and next workup.

Glucose-corrected Na (Katz/Hillier), tonicity, free-water excess, ODS-risk ceiling. qwen 14b ranked differential keyed to volume status + meds.

Live countdown + per-element status. Optional qwen 14b evidence sidebar cached 7 days per user. No LLM on the main path.

11-item bedside stroke severity score (0-42). Bands: no stroke / minor / moderate / moderate-severe / severe — drives tPA candidacy and disposition.

Age, BP, clinical features, duration, diabetes. Three bands (low / moderate / high) drive admission vs urgent outpatient workup.

Confusion, Urea, RR, BP, age ≥65. Maps directly to outpatient / short inpatient / hospitalize with mortality bands.

Nine positive + one negative criterion (alt diagnosis). Three-tier band sets the D-dimer vs compression-US threshold.

Decimal weights across 7 items. Reports BOTH three-tier (low / moderate / high) AND two-tier (likely vs unlikely) bands.

History, ECG, Age, Risk factors, Troponin. 0-10 score with low / moderate / high MACE bands — discharge vs admit vs invasive.

7 binary items, score 0-7 with per-score 14-day MACE bands from the original TIMI 11B / ESSENCE cohorts.

6 organ systems × 0-4 = 0-24. Mortality bands plus optional qSOFA chip — flags positive at ≥2/3 bedside criteria.

All three formulas computed in parallel. Sex-specific Bazett band; any-method >500 ms flags high TdP risk.

8 clinical / lab items (T and L worth 2 pts each). Bands map directly to discharge / observe / surgical consult / surgery.
