Weight-based dose with ideal and adjusted dosing weight: obesity band threshold · case 01

Patients a few kilograms over ideal weight are dosed on an adjusted weight instead of ideal weight.

ROOT CAUSE

The adjusted-weight branch triggers on any weight above IBW rather than only above 120% of IBW.

VERIFIED REPAIR

Enter the adjusted branch only when actual weight is strictly greater than 1.2 x IBW.

Unsuccessful approach: Using >= 1.2 x IBW restores the percentage but moves a patient at exactly 120% into the adjusted band, contrary to the inclusive ideal band.

Case contract

Input {sex, height_in, weight, unit ("kg" or "lb", 1 kg = 2.2 lb), mg_per_kg, max_mg}. Toy rule: IBW = 50 kg (sex "M") or 45.5 kg (otherwise) + 2.3 kg per inch above 60 in (never below the base). Dosing weight is actual weight when below IBW, IBW when actual is within 100-120% of IBW inclusive, and IBW + 0.4*(actual-IBW) when actual exceeds 120% of IBW. Dose = mg_per_kg * dosing weight rounded half-up to the nearest 5 mg, then capped at max_mg. Return {basis, dosing_weight_kg (1 decimal), dose_mg}.

Why this case matters

Weight-based ordering tools must choose the stipulated dosing weight band, convert units exactly, and apply the ceiling after the final rounding step.

Verification & scope

A deterministic toy software model with explicitly stipulated thresholds and formulas; it is not clinical guidance, not a validated medical calculator, and makes no claim of conformance to any published protocol. Numbered variants vary patient and order inputs. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
