- Table 1. Mortality risk scoring system for patients with idiopathic pulmonary fibrosis
Risk factors Score Age years ≥70 8 60–69 4 <60 0 Recent respiratory hospitalisation Yes 14 No 0 Baseline FVC % predicted ≤50 18 51–65 13 66–79 8 ≥80 0 24-week change in FVC % predicted ≤ -10 21 -5 to -9.9 10 > -4.9 0 FVC: forced vital capacity. Sum the individual scores corresponding to the level of each risk factor for a given patient, e.g. the total score for a patient aged 70 years, with no history of respiratory hospitalisation, FVC 51–65% predicted, and a 24-week change in FVC of -5 to -9.9% predicted is 8+0+13+10=31.

Total risk score Expected 1-year probability of death % 0–4 <2 8–14 2–5 16–21 5–10 22–29 10–20 30–33 20–30 34–37 30–40 38–40 40–50 41–43 50–60 44–45 60–70 47–49 70–80 >50 >80 The total points from table 1 are used to calculate the expected 1-year probability of death, e.g. a patient with a total risk score of 31 has a predicted 1-year probability of death of 20–30%.
