Background/Objectives: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive fibrotic interstitial lung disease with high mortality and limited treatment options. Despite recent therapeutic advances, predicting survival remains challenging. Given the challenge of predicting disease progression in IPF, identifying reliable prognostic markers may support individualized treatment strategies, guide follow-up intensity, and improve clinical decision making. This study aimed to evaluate mortality rates and factors associated with poor prognosis in patients with IPF over a 10-year period at a tertiary care center. Methods: Medical records of 268 patients diagnosed with IPF between 2015 and 2024 were retrospectively reviewed. Demographic characteristics, comorbidities, radiological findings, pulmonary function test results, frequency of exacerbations and hospitalizations, treatment details, and survival outcomes were analyzed. Univariate and multivariate logistic regression analyses were performed to identify predictors of mortality. Results: This study included 268 patients (77.2% male; median age, 72 years). During a median follow-up of 24 months, 44% (n = 118) of patients died. Deceased patients were older (p < 0.001) and had higher rates of coronary artery disease, pulmonary embolism, pulmonary hypertension, and malignancy (all p < 0.05). A definite UIP pattern was more common among deceased patients (71.2% vs. 52.4%, p = 0.02). Acute exacerbations (23.3% vs. 8.1%) and hospitalizations (61.9% vs. 23.3%) were significantly more frequent in this group (p < 0.001). In multivariate analysis, GAP score (OR 11.68, p = 0.001), pulmonary hypertension (OR 15.39, p = 0.02), history of exacerbation (OR 56.2, p = 0.04), baseline FVC (OR 1.10, p = 0.02), mean platelet volume (OR 0.29, p = 0.01), and AST level (OR 1.12, p = 0.04) were independent predictors of mortality. Conclusions: Despite advances in management, IPF continues to carry a high mortality risk. This study represents one of the largest single-center IPF cohorts from our region with long-term real-life follow-up and additionally evaluates laboratory biomarkers such as MPV and AST, which have not been widely investigated as prognostic indicators in IPF. Advanced age, reduced pulmonary function, comorbidities, and acute exacerbations are major prognostic factors. Early recognition and proactive management of these parameters may help improve survival outcomes.
