Data analytics in healthcare refers to the process of systematically examining vast amounts of health-related data to uncover patterns, correlations, and insights that can lead to informed decision-making. This involves collecting, processing, and analyzing data from various sources, including electronic health records (EHRs), wearable devices, medical imaging, patient surveys, and more. The ultimate goal is to use these insights to enhance patient care, streamline operations, and drive innovation in medical research.
Healthcare data analytics combines various data types, such as structured data (numerical or categorical data) and unstructured data (free-text entries, medical images), to generate actionable insights. The process involves several stages, including data collection, data cleaning, data integration, data analysis, and data visualization. Each stage plays a crucial role in ensuring the accuracy and reliability of the insights derived.
Applications of Data Analytics in Healthcare
