Current Challenges of Data Analytics in Healthcare Healthcare data analytics faces major obstacles that limit its potential. These challenges affect how organizations collect, process, and use patient information for better care.
Security breaches remain the biggest threat In 2024, the USA alone had 585 incidents of data breaches with 180 million compromised user records. The numbers are staggering. In 2024, there were 14 data breaches involving more than 1 million healthcare records, including the biggest healthcare data breach of all time that affected an estimated 190,000,000 million individuals. Between January and September 2024, healthcare organizations in the United States saw 491 large-scale data breaches, resulting in the loss of over 500 records.
Data fragmentation creates operational nightmares One of the biggest challenges in developing such apps is the distribution of health information among many databases, or “data structure.” Patient records sit in separate systems that don’t talk to each other. Electronic health records, lab results, imaging data, and pharmacy information exist in isolated silos.
