Summary
This study introduces dynamic access rules for healthcare systems by integrating workflow data. This approach aims to improve patient privacy and reduce emergency access overrides in hospitals.
Area of Science:
- Health Informatics
- Computer Science
Background:
- Healthcare information systems require robust access control for patient privacy and professional access.
- Existing access control mechanisms are often static and fail to adapt to real-world hospital operations.
Purpose of the Study:
- To develop dynamic access rules for healthcare information systems.
- To adapt access control to the actual workflow within a hospital.
- To minimize the reliance on "break the glass" access procedures.
Main Methods:
- Combining workflow information from medical guidelines.
- Utilizing observations and audit logs.
- Creating adaptive, dynamic access rules.
Main Results:
- Proposed a novel method for dynamic access rule generation.
- Demonstrated potential for adapting access control to hospital workflows.
- Aimed to reduce the frequency of "break the glass" access events.
Conclusions:
- Dynamic access rules offer a more adaptive solution to healthcare information system security.
- Integrating workflow data enhances the relevance and effectiveness of access control.
- The proposed approach can improve patient privacy and streamline professional access.

01:25Ethical Standards I
The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

01:20Integrated Healthcare System
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

The legal guidelines for nursing documentation are essential for ensuring accurate, professional, and ethical recording of patient care. The guidelines are discussed here:
01:29Issues And Trends In Healthcare Delivery System
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
