the password protected zone of the USB flash drive was defective and she could not
access the data kept in that zone. Instead of reporting the incident to the relevant
supervisor, she chose to copy the data again from the master computer file and stored
it in the non-password protected zone of the USB flash drive, which was later lost. The
Commissioner found that HA, as the employer of the nurse, had breached DPP4 in failing
to take all practicable steps to protect patients’ personal data in view of the deficiency
of policies and practices regulating the use of mobile electronic storage devices and
the lack of training provided to its staff. The series of reported data breach incidents in
2008 concerning the loss of patients’ personal data revealed the inadequacies of the
patients’ data security system operated by HA. This prompted the Commissioner to carry
out a self-initiated inspection under section 36 of the Ordinance resulting in a number of
recommendations for HA to improve its data security system for patients’ data.

More recently, an investigation
20
was carried out by the Commissioner against HA which
resulted in an enforcement notice being served to HA for contravention of DPP4. The
investigation stemmed from two data leakage incidents in which hospital waste
containing patients’ personal data and shredded strips of medical appointment slips
were found abandoned outside the shredding factory of a waste disposal service
provider engaged by HA. The Commissioner concluded that the precise cause of
abandonment of the hospital waste was unknown but the leakage of the personal data
in question was clearly an outcome of incomplete or improper shredding of the hospital
waste. By virtue of section 65(2) of the Ordinance, even though HA had entrusted its
service provider with the task of hospital waste collection, destruction and disposal, HA
remained accountable as data user for any unauthorised or accidental access of the
personal data in question. Furthermore, the contract between HA and its service
provider was found by the Commissioner to be inadequate to ensure proper and
complete shredding of hospital waste, and HA failed to competently manage the
contract. The Commissioner therefore concluded that HA had contravened DPP4 as it
had failed to take all reasonably practicable steps to ensure that patients’ personal
data were protected against unauthorised or accidental access. HA was directed
under the enforcement notice to exercise its reasonable endeavors to retrieve and
destroy the abandoned hospital waste identified in the two incidents, review and revise
the hospital waste disposal procedures and implement a series of improvement
measures, etc., within a specified period.

In another case, a patient visited a clinic and discovered that his file containing his
medical records had been lost. The clinic tried to track and trace the records but to no
avail and it was unable to ascertain when the loss had occurred and who had caused
the data loss. The Commissioner found that the clinic had no system in place to monitor
the movement of the files containing medical records and, owing to the busy
movement of these files during consultation periods, any loss would easily escape the
