Integrating AI into existing EHR systems, hospital workflows, and medical imaging platforms necessitates major investments in software, training, and infrastructure changes [78]. Additionally, interoperability concerns across different healthcare systems complicate AI deployment. Standardizing AI implementation and creating interoperable frameworks can help to easy integration [79].
5.5 Regulatory and Legal Challenges
The use of AI in medicine creates significant legal and regulatory issues. Current medical rules are frequently not built to support AI-driven diagnosis and treatment suggestions, making it difficult to develop guidelines for AI approval and supervision [80]. Regulatory authorities like as the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) are developing frameworks to ensure AI-powered healthcare solutions meet safety, efficacy, and ethical requirements [81, 82]. However, striking a balance between innovation and patient safety remains a major challenge.
5.6 Ethical Considerations for AI-Driven Healthcare
The ethical implications of AI in medicine go beyond privacy and bias to include concerns like patient autonomy, informed consent, and liability [83]. For example, if an AI system provides an inaccurate diagnosis or treatment prescription, deciding who is to blame—the AI developer, the healthcare professional, or the institution—becomes a legal and ethical quandary [84]. Furthermore, AI should supplement, not replace, human decision-making, ensuring that physicians maintain control over patient care. Ethical AI guidelines should be developed to guide the responsible application of AI in healthcare [85].
The future of AI in medicine seems bright, with advances in deep learning, predictive analytics, and robotic systems continuing to change healthcare. As AI technologies advance, they will improve early disease detection, precision medicine, and patient-centered treatment.
