Abstract Background Accurate diagnosis of idiopathic pulmonary fibrosis (IPF) is essential to inform prognosis and treatment. In 2018, the ATS/ERS/JRS/ALAT and Fleischner Society released new diagnostic guidelines for usual interstitial pneumonitis (UIP)/IPF, adding Probable UIP as a CT category based on prior studies demonstrating this category had relatively high positive predictive value (PPV) for histopathologic UIP/Probable UIP. This study applies the 2018 ATS/ERS/JRS/ALAT and Fleischner Society guidelines to determine test characteristics of CT categories in academic clinical practice. Methods CT and histopathology were evaluated by three thoracic radiologists and two thoracic pathologists. Comparison of consensus categorization by the 2018 ATS and Fleischner Society guidelines by CT and histopathology was performed. Results Of patients with CT UIP, 87% (PPV, 95% CI: 60–98%) had histopathologic UIP with 97% (CI: 90–100%) specificity. Of patients with CT Probable UIP, 38% (PPV, CI: 14–68%) had histopathologic UIP and 46% (PPV, CI: 19–75%) had either histopathologic UIP or Probable UIP, with 88% (CI: 77–95%) specificity. Patients with CT Indeterminate and Alternative Diagnosis had histopathologic UIP in 27% (PPV, CI: 6–61%) and 21% (PPV, CI: 11–33%) of cases with specificities of 90% (CI: 80–96%) and 25% (CI: 16–37%). Interobserver variability (kappa) between radiologists ranged 0.32–0.81. Conclusions CT UIP and Probable UIP have high specificity for histopathologic UIP, and CT UIP has high PPV for histopathologic UIP. PPV of CT Probable UIP was 46% for combined histopathologic UIP/Probable UIP. Our results indicate that additional studies are needed to further assess and refine the guideline criteria to improve classification performance.

Idiopathic pulmonary fibrosis (IPF) is a specific form of chronic, progressively fibrosing interstitial pneumonia that is associated with a significantly worse prognosis than other forms of chronic interstitial pneumonia. An early and accurate diagnosis of IPF is important to enable the initiation of disease-specific therapies, which have the potential to reduce disease progression, and the avoidance of inappropriate and potentially harmful drugs. Establishing an accurate diagnosis of IPF can be challenging. Recent studies and international guidelines advocate the importance of a multidisciplinary team (MDT) in the initial diagnostic assessment of patients with suspected IPF. Typical MDT members include a pulmonologist, a radiologist and a pathologist, with further input from a thoracic surgeon, a rheumatologist, a specialist nurse and an occupational physician where appropriate. Multidisciplinary diagnosis is considered the gold standard because it can improve the accuracy of diagnosis of IPF, avoid unnecessary testing (e.g. lung biopsy), and optimise patient management. Here we highlight the strengths and limitations of the multidisciplinary approach to IPF diagnosis through MDT discussion of two patient cases.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, and fatal lung disease of unknown origin. Despite recent advancements, the diagnosis and management of IPF remains a distinct clinical challenge; as a result, patients often experience considerable delays in receiving an accurate diagnosis and confusion regarding prognosis and the availability of treatment options. In order to gain further insights regarding patients' perspectives on the diagnostic process, disease education, emotional well-being, and quality of life, we conducted a qualitative in-depth survey among IPF patients in Europe. Patients with a physician-confirmed IPF diagnosis were recruited to participate in an in-depth interview conducted by a trained facilitator who used a qualitative topic guide. A total of 45 patients from 5 European countries participated in the survey. The median reported time from initial presentation to confirmed diagnosis of IPF was 1.5 years (range <1 week to 12 years); in 58% of cases there was a delay of >1 year between initial presentation and a confirmed diagnosis of IPF. Additionally, 55% of patients reported consulting ≥3 physicians before receiving an IPF diagnosis. Patient satisfaction with medical care and disease education appeared to be higher among patients who were receiving care at a recognized center of excellence. Patients generally had reasonable expectations regarding the goals of therapy, with most recognizing the irreversibility of the disease and the limited prospects for achieving a cure. The most common unmet needs cited by participants were disease education resources, access to centers of excellence, and familial support programs. Our findings suggest that patients with IPF commonly experience protracted delays in receiving an accurate diagnosis and generally perceive the level of medical care as suboptimal, despite expressing reasonable expectations regarding the goals of therapy. These results support the need for further improvement in the areas of diagnosis, disease management, and patient education.

Chronic hypersensitivity pneumonitis (HP) arises from repeated exposure to causative antigens. Although HP can be challenging to diagnose, it is important to differentiate from idiopathic pulmonary fibrosis and idiopathic non-specific interstitial pneumonia. HP has a unique management approach and portends a unique prognosis. The present article summarizes the recent published literature on chronic HP and highlights the features that may be helpful in distinguishing it from other chronic interstitial lung diseases.
