什么是医疗数据隐私法（GDPR、HIPAA、PIPEDA）？

Healthcare data privacy laws vary by region but share common principles: protecting patient information, requiring informed consent, ensuring secure storage, and mandating breach notifications. Key regulations include GDPR (European Union) covering all personal data with strict consent requirements, HIPAA (United States) governing protected health information, PIPEDA (Canada) for private-sector health data, and various national laws worldwide. Dental practices operating internationally or treating foreign patients must understand which regulations apply to them and ensure their systems meet compliance requirements across jurisdictions.
