AbstractIdiopathic pulmonary fibrosis (IPF) is the most common idiopathic interstitial pneumonia, a form of interstitial lung disease characterized by abnormal wound healing in the lung that leads to progressive scarring and loss of lung function. Comorbidities are highly prevalent in IPF and often lead to further complications and worse outcomes. In fact, undetected and untreated comorbidities are independently associated with poor outcomes. IPF not only affects patient quality of life (QOL) but also requires significant cost for delivering care. Given the potential for rapid progression of IPF and the associated risk for mortality, early diagnosis is critical for retaining the highest lung function and QOL for as long as possible. Delayed diagnosis of IPF is associated with increased costs in terms of investigations performed, and delayed referral can result in lower survival rates independent of disease severity or associated prognostic factors. Significant progress has been made in understanding IPF pathogenesis, which has, in turn, led to the development of novel therapeutic options that improve outcomes, extend life, and minimize disease burden on patients' daily lives. For patients with IPF in the absence of underlying liver disease, pirfenidone and nintedanib are licensed for the treatment of IPF. Additionally, a number of investigational therapeutic options are currently in development. The extent of clinical effectiveness compared with the cost of therapy has led to a lack of consensus on the cost-vs-benefit analyses for the drugs.
