Chronic Obstructive Pulmonary Disease (COPD), afflicting over 300 million people globally, constitutes a significant contributor to morbidity and mortality, with patients manifesting severe COPD having a 2-year survival rate of 50%. COPD is characterized by chronic respiratory symptoms like difficulty breathing, cough and fluid filled airways, at times worsening rapidly in episodes known as exacerbations. Despite treatment advancements, generic "one size fits all" approaches fail to prevent COPD exacerbations in most patients, emphasizing the need for personalized treatment strategies due to the disease's varied pathogenesis. The primary goal of my project was to use electronic health record (EHR) data to characterize COPD exacerbations, apply computational methods for identifying patient clusters with similar disease indicators, and develop personalized treatment strategies to enhance patient outcomes. Data from over 8300 participants was extracted from deidentified clinical notes through natural language processing techniques and approximately 20 clinical features were extracted per patient. K-means clustering was then used to categorize the cohort into three distinct and homogenous subgroups based on disease indicators such as serum biomarkers, comorbidities, symptoms, demographics, and respiratory characteristics. Forced Expiratory Volume (FEV1) and breath sounds were the key differential indicators that were identified among these subgroups as identified through Principal Component Analysis. Random forest and Bayesian optimization were employed to build a predictive model in patient subgroups, considering the presence or absence of exacerbations alongside treatment data, aiming to predict personalized treatment approaches while incorporating real-time breath sounds and FEV data for enhanced efficacy. Prognostic matching was then employed alongside the predictive model to further optimize treatment plans based on empirical data. These results were then validated by physicians with a high level of confidence, significantly higher than the physician prescribed treatment plans for the same patient. Further, in collaboration with a telemedicine startup, efforts are underway to integrate these models into EHR modules to enable patient-specific treatments, improving outcomes and survival rates. This methodology marks a significant improvement in the treatment plan of Chronic Respiratory Diseases, helping physicians in their decision making process.
