Management of your data protection risks is critical for growing businesses. It helps build serious patient/customer trust, minimises the risks of regulatory fines and reduces the impact of a cyber-attack. A key question that I’m asked at least once a week is ‘When do I need to appoint a Data Protection Officer (DPO)?’

A DPO is a person responsible for compliance with data protection laws. Under the UK GDPR, a DPO has a set of specific tasks to help them carry out their aim of protecting individuals from the harm that can arise when personal data is misused, lost or stolen. 

When Is a DPO Required?

Under UK GDPR, a DPO is a statutory obligation and mandatory if your business:

  • Is a public body
  • Processes patient data on a large scale, including health records, genetic, or biometric data
  • Engages in systematic monitoring of patients, such as health tracking apps, large-scale CCTV or online monitoring 

Given the significance of harm and the impact of a major data breach or cyber-attack on the business, even when not legally required, businesses that handle particularly sensitive data, such as health or biometric data, should consider appointing a DPO or assigning responsibility to an existing member of staff to ensure the risk is appropriately managed. 

Signs You’re ready to appoint a DPO

Your clinic or healthcare business will benefit from a DPO if you:

  • Handle sensitive patient data regularly
  • Have multiple staff members processing patient information
  • Use complex IT systems or cloud-based record management
  • Have received frequent data requests or have dealt with a data breach

Benefits of Appointing a DPO

  • Ensure compliance with GDPR and reduce the risk of fines
  • Streamline responses to patient data requests and breaches
  • Build patient trust by demonstrating strong data protection practices

Internal vs External DPO

  • Internal: A staff member with sufficient data protection expertise
  • External: A consultant providing expert guidance, which can often be more cost-effective for growing clinics.

Conclusion
If you're regularly using the health information of thousands of people or you monitor behaviour on a large scale, you need to consider introducing a data protection officer to support your long-term growth plan. Smaller practices or businesses can benefit from thinking about this risk early and taking steps to prepare for future growth, data protection officer
