Inquirer reporter Sarah Gantz uses Pennsylvania hospital inspection reports and data tools to investigate patient safety across Philadelphia-area hospitals. Her reporting has uncovered serious issues such as medical errors, neglect, unsafe practices, and systemic problems in hospital care, including cases that led to patient harm or death. By building a database and regularly tracking violations, she has created a public accountability system that helps surface recurring safety failures and prompts hospital responses. Her work has led to deeper scrutiny of hospital practices, changes in some cases, and broader attention to how reporting systems and hospital culture affect patient safety.
