RESECT-90 Score calculator

Enter the published formula inputs below to calculate and interpret this score.

Clinical inputs

Age

years

Allowed range: 18–100 years

Sex

Performance status

grade

Allowed range: 0–4 grade

WHO or ECOG grade from 0 to 4. Each grade adds 0.183 to the logit.

Percent predicted DLCO

% predicted

Allowed range: 5–200 % predicted

Diffusing capacity of the lung for carbon monoxide, as a percent of the predicted value.

Body mass index

kg/m2

Allowed range: 10–70 kg/m2

Serum creatinine

mg/dL

Allowed range: 0.23–16.97 mg/dL

The model uses µmol/L. A value typed in mg/dL is multiplied by 88.4 before the coefficient 0.005 is applied.

Haemoglobin

g/dL

Allowed range: 4–22 g/dL

The model uses g/L. Anaemia is haemoglobin below 120 g/L in women and below 130 g/L in men. A value at the threshold is not anaemic. A value typed in g/dL is multiplied by 10.

Preoperative arrhythmia

Right-sided resection

Resected bronchopulmonary segments

segments

Allowed range: 0–20 segments

Count of bronchopulmonary segments removed. Each segment adds 0.179 to the logit.

Open thoracotomy

Malignant diagnosis, confirmed or suspected

Taylor M et al. Development and internal validation of a clinical prediction model for 90-day mortality after lung resection: the RESECT-90 score. Interact Cardiovasc Thorac Surg. DOI: 10.1093/icvts/ivab200. PMID: 34324664. The printed equation is logit = −6.036 + 0.041×age in years + 0.493 if male + 0.183×performance status + −0.029×percent predicted DLCO + −0.056×BMI in kg/m2 + 0.005×creatinine in µmol/L + 0.242 if anaemic + 0.608 if arrhythmia + 0.379 if the resection is right-sided + 0.179×number of resected bronchopulmonary segments + 0.634 if thoracotomy + 0.769 if the diagnosis is malignant. Probability = 1 / (1 + exp(−logit)). Table 3 lists the same coefficients. Anaemia is haemoglobin below 120 g/L in women and below 130 g/L in men. The paper does not print a probability cutoff. (2021)

Scope: Adults undergoing lung resection, including wedge resection, segmentectomy, lobectomy, bilobectomy, or pneumonectomy. Creatinine is entered in µmol/L. Haemoglobin is entered in g/L.
