Advanced AI-powered tools swiftly analyze patient data in medical charts for identifying suitable candidates more precisely compared to traditional human approaches [11]. Advanced natural language processing techniques improve hiring processes by identifying pertinent health data embedded in informal healthcare records [12]. Moreover, these strategies contribute positively towards enhancing the inclusion of various demographic groups in healthcare services. [13].

2. 3 Clinical Data Monitoring and Management

Artificial intelligence showcases substantial benefits by streamlining tasks such as managing medical records efficiently, ensuring accuracy through automated data verification, identifying errors promptly, and maintaining uniformity across datasets [14]. Systems utilizing risk assessment through artificial intelligence pinpoint critical locations and unusual data patterns for focused scrutiny while minimizing surveillance expenses [15].

2. 4 Safety Surveillance and Pharmacovigilance

Advanced technologies leveraging artificial intelligence are being employed more frequently for early detection of potential risks through analysis of incident records, patient histories, and ongoing health assessments after product release [16]. Advanced machine-learning techniques surpass traditional methods in detecting early warning signs of risks, facilitating prompt intervention for security purposes [17]. Enhancing these features strengthens safeguarding patients' rights and ensures adherence to regulations [18].

2. 5 Advanced Data Analysis and Precision Medicine

Artificial intelligence facilitates intricate examination of complex data sets, aiding in categorizing patients, forecasting treatments' effectiveness, and identifying biological markers [19]. Advanced machine-learning methods excel at merging medical records, diagnostic images, and genetic information for tailoring treatments specifically to individual patients [20]. Nevertheless, issues concerning model explainability continue[21].

3. Opportunities for AI Integration
