Protecting patient data: practical controls for clinics and hospitals.

Health information is among the most sensitive data a business can hold. Its protection is a duty, and a trust issue.

Principles

The widely used safeguards, reflected in frameworks such as HIPAA and in India’s DPDP Act, fall into familiar groups: administrative (policies, training, risk assessment), physical (rooms, devices) and technical (access control, audit, integrity and transmission security).

Who should see what

Design access so that only the consulting doctor and the patient can open a given record. Other staff see only what their role requires. Emergency access can exist, but through a “break-glass” process that is logged and reviewed afterwards.

Technical controls

• Encrypt the patient database and backups, and encrypt data in transit.
• Use multi-factor authentication for clinical staff and administrators.
• Keep an audit trail of every view, change and export.
• Separate networks for clinical systems, medical devices, administration and guests.
• Use private, secure links between the hospital, laboratories and partner organisations.
• Mask or de-identify data used for reports and analytics.

Day-to-day practice

Lock screens, limit shared logins, secure printers, control removable media and dispose of old devices through verified erasure.

Vendors and tie-ups

Laboratories and pharmacies handling your patients’ data should work under written agreements that set confidentiality and security expectations.

Be honest about claims

Designs can be aligned to these safeguards, but formal compliance is something your own compliance advisers assess.
