SEU Expert systems and decision support Discussion

Expert Solution Preview

Introduction:

As a Harvard University Professor, my role is to design and conduct lectures, evaluate student performance, and provide feedback through examinations and assignments. In this assignment, I shall answer three questions related to public health, health informatics, and data security in the healthcare industry.

1. Decision support and expert systems are needed in public health for three basic reasons. Identify, explain, and provide an example of each reason?

The three basic reasons why decision support and expert systems are essential in public health are as follows:

i. To improve decision-making: Decision support systems help healthcare professionals make informed, evidence-based decisions that improve patient outcomes. For example, clinical decision support tools alert doctors if a patient’s medication has the potential to interact with another medicine they are taking.

ii. To enhance efficiency: Expert systems can automate routine tasks, reducing the workload on healthcare providers and freeing them up for more complex tasks. For instance, an expert system can help in medical image analysis, making it easier for radiologists to diagnose cancer.

iii. To reduce errors: Decision support and expert systems can help identify errors before they happen, prevent incorrect diagnoses, and avoid adverse events like medication errors. An example of this is the use of an automated surveillance system to monitor and alert healthcare providers about potential infections.

2. There are many ways to view the discipline of global health informatics. What are two of the defining attributes that set the discipline of global health informatics apart from other informatics disciplines?

The two defining attributes that set the discipline of global health informatics apart from other informatics disciplines are:

i. Focus on global health disparities: Global health informatics focuses on addressing health disparities that exist between developed and underdeveloped regions. Global health informatics researchers work to develop technological solutions to improve access to health information in low and middle-income countries.

ii. Interdisciplinary approach: Health informatics draws from various fields of study, including computer science, medicine, and public health, to develop technologies that can improve health outcomes. In the context of global health informatics, international collaboration between researchers, policymakers, and health professionals can aid in the development of novel approaches to healthcare delivery.

3. What are the risks to the security of health-related data? What are the roles of information technology to help protect them?

The risks to the security of health-related data include:

i. Unauthorized access: Hackers can gain unauthorized access to sensitive patient data, such as social security numbers and medical histories.

ii. Malware attacks: Malware attacks, such as ransomware and phishing, can occur when hackers use malicious software to gain access to sensitive data.

iii. Internal threats: Unauthorized employees accessing patient records can also pose a security threat.

Information technology plays a crucial role in safeguarding health-related data by:

i. Implementing access-control measures: Access control measures, such as username and password authentication, can prevent unauthorized access to sensitive patient data.

ii. Encryption: The use of encryption technology can help protect patient data when it is being transferred or stored.

iii. Regular software updates: Keeping software up-to-date can prevent malware attacks by patching vulnerabilities in the system.

Conclusion:

As a Harvard University Professor, I believe that these are crucial topics that health informatics students need to understand. By understanding the challenges and potential solutions in this field, students can be better equipped to develop innovative technologies that improve patient outcomes and contribute to global health equity.
