Systematic Review of Artificial Intelligence Applications in Healthcare
The technology known as Artificial Intelligence in Healthcare is now considered to be one of the most innovative and revolutionary tools in modern-day healthcare. AI is defined as a computer system able to complete those tasks which generally would require human intellect such as learning, making conclusions, decision making, and recognizing patterns. During the last decade, thanks to developments in Machine Learning in Healthcare, deep learning (DL), natural language processing (NLP), and computer vision, healthcare services have greatly benefited in terms of accuracy and speed.[1]
Healthcare providers more and more use AI technology to facilitate Clinical Decision Support, decrease the number of mistakes, increase efficiency, and improve patient outcomes. At the same time, questions about data protection, ethics, transparency of algorithms, and other regulatory aspects are still the biggest issues. This Systematic Review AI highlights the current state of Healthcare Artificial Intelligence in terms of its application, benefits, limitations, and future perspectives.
1. Methodology
A systematic literature review was carried out by searching for scientific articles from peer-reviewed journals published from 2019 to 2025. Relevant search engines like PubMed, Scopus, Web of Science, IEEE Xplore, and Google Scholar were explored through the following keywords:
- Artificial Intelligence
- Machine Learning
- Deep Learning
- Healthcare
- Clinical Decision Support
- Medical Imaging
Inclusion Criteria
- English language articles
- Research articles and systematic reviews
- Studies focusing on AI application in healthcare
Exclusion Criteria
- Editorials
- Conference abstracts
- Duplicate studies
- Non-healthcare AI applications
After searching the existing literature, the relevant literature was critically analyzed for the identification of AI applications, benefits, challenges, and future prospects.
2. Applications of Artificial Intelligence in Healthcare
There is tremendous potential of artificial intelligence in several aspects of healthcare.[2]
Diagnostic Imaging: AI in Medical Imaging help the radiologists to detect various illnesses like cancer, stroke, pneumonia, and diabetic retinopathy using automatic image interpretation techniques. Deep learning systems provide diagnosis at an accuracy level equivalent to that of trained professionals.
Clinical Decision Support Systems: Clinical Decision Support systems analyze patients’ data including test results, imaging and clinical history to suggest effective treatment choices without making medical mistakes.
Drug Discovery: Developing a drug using conventional processes takes more than 10 years and huge amounts of money. AI helps identify targets, screen molecules, predict their toxicity, and optimize clinical trials.
Personalized Medicine: Personalized Medicine AI combines genomic, clinical, and lifestyle data to provide individualized treatment by increasing effectiveness and decreasing adverse drug effects. [3]
Remote Patient Monitoring: Wearable gadgets fitted with AI systems continuously monitor heart rate, blood glucose, blood pressure, oxygen saturation and physical activities to detect any irregularities.
Robotic Surgery: AI-driven robotic surgery improves surgical accuracy through enhanced visualization and instruments control.[4]
3. Major Applications of AI in Healthcare
| Application | AI Technology | Clinical Benefit |
| Medical Imaging | Deep Learning | Improved diagnostic accuracy |
| Clinical Decision Support | Machine Learning | Evidence-based treatment decisions |
| Drug Discovery | Predictive Analytics | Faster drug development |
| Personalized Medicine | Genomic AI | Individualized therapies |
| Remote Monitoring | Wearable AI | Early disease detection |
| Robotic Surgery | Computer Vision | Increased surgical precision |
4. Benefits and Challenges of AI in Healthcare
Healthcare organizations must develop robust governance frameworks to ensure responsible AI deployment while maintaining patient confidentiality and regulatory compliance.
5. Future Perspectives
However, the future of Artificial Intelligence in Healthcare looks very bright. Future technologies such as XAI, federated learning, generative AI, and digital twins are anticipated to make the process more transparent, secure, and personalized in terms of healthcare delivery. The integration of AI with EHRs, wearable technologies, and IoMT devices will help provide real-time analytics and precision medicine.
It is crucial for further research to develop an algorithm which would be equitable, transparent, and interpretable. In addition, regulatory guidelines need to be developed. It will be necessary to collaborate with clinicians, engineers, policymakers, and researchers.
