University Hospitals Coventry and Warwickshire is a large acute teaching NHS trust which serves a population of over 1 million. There has been an ILD MDT since 2006. In July 2010 a consultant with an interest in ILD was appointed. The MDT constitutes a thoracic surgeon, pathologist and radiologist with expressed interest in ILD.
To describe the spectrum of ILD presenting in secondary care.
It is departmental policy to discuss all incident cases of ILD in the MDT. Diagnoses were made according to BTS guidelines, and by consensus. Numbers were compared by χ2, and ages by Mann-Whitney U-test.
From September 2010 to July 2011, 89 suspected cases were discussed in the ILD MDT, 10 of whom proved not to have significant ILD. The diagnoses of the remaining 79 are given in table below.

DiagnosisNumberMedian AgeRange
Hypersensitivity Pnuemonitis257.546-69
Idiopathic Pulmonary fibrosis (IPF)127757-81
Other Idiopathic Interstial Pnuemonia336644-84
Smoking Related95035-70

Definite IPF made up 15% of the cohort, with a median age of 77. Smoking related ILD — Respiratory Bronchiolitis associated ILD and Desquamative Interstitial Pneumonia — account for (11%) of cases. The median age of diagnosis is 27 years younger than those with IPF (p<0.001).
Smoking related ILD makes a significant proportion of cases discussed at the ILD MDT. Patients are significantly younger than those with IPF. This may reflect an increasing awareness of the radiological and pathological appearance of these diseases.
