Mohamed Ali Saleh Abomhara

PhD Candidate

The thesis Mohamed Ali Saleh Abomhara defends for his PhD investigates how health care professionals can access the patient information they need to perform their duties without accessing sensitive patient information.

Mohamed Ali Saleh Abomhara defends his PhD thesis An Access Control Model to Facilitate Healthcare Information Access in Context of Team Collaboration on Tuesday 18 December 2018.

He has been enrolled in the doctoral programme of the Department of ICT at the Faculty of Engineering and Science.

This is how the PhD Candidate expresses the main points of his thesis:

Healthcare teams and secure access to patient information

The delivery of healthcare relies on the sharing of patients’ information among a group of healthcare professionals.

At present, electronic health records (EHRs) are widely utilized system to create, manage and share patient healthcare information among healthcare teams.

Accidental or intentional abuse

While it is necessary to provide healthcare professionals (members of the healthcare team) with privileges to access patient health information, providing too many privileges may backfire when healthcare professionals accidentally or intentionally abuse their privileges.

Ensuring patient privacy and improving patient care quality are two of the most significant challenges faced by healthcare systems around the world. Hence, finding a middle ground, where the necessary privileges are provided and malicious usage is avoided, is necessary.

PhD focus: Collaborative activities

This PhD study highlights the access control matters in the collaborative healthcare domain.

Focus is mainly on the collaborative activities that are best accomplished by organized healthcare team within or among healthcare organizations with an objective of accomplishing a specific task (patient treatment).

We investigate the importance and challenges of effective healthcare team treatment, the sharing of patient health records in healthcare delivery, patient data confidentiality and the need for flexible access of the members of the team corresponding to the requirements to fulfil their duties.

The focus is on developing an access control model that balances between healthcare team collaboration and safeguarding sensitive patient information.

Access control model

The major contributions of our access control model include ensuring that access rights are adapted to the actual needs of healthcare providers and providing fine-grained control of access with the minimum necessary standard, whereby healthcare providers are granted minimal access to carry out their duties.
