LITERATURE REVIEW

In the past few decades, artificial intelligence (AI) has been widely accepted as a transforming force in the healthcare sector. Advances in AI technologies over the past decades have led to its widespread use in all dimensions of healthcare: diagnosis, treatment planning, and management of patients.

Overview of AI in Healthcare History the history of AI in healthcare began in the 1970s, starting with the development of expert systems, including MYCIN and INTERNIST-1, intended to aid in medical diagnostics and decision-making. This created the foundational work for further innovative developments in AI. Ever since machine learning algorithms and big data analytics integration have propelled it into mainstream healthcare applications.

Key Theories and Models. Machine learning, deep learning, natural language processing, and computer vision are some of the main theories and models upon which AI in healthcare is founded. Algorithms that fall under the category of machine learning include decision trees, support vector machines, and neural networks, all of which have produced impressive accuracy when predicting disease outcomes and identifying risk factors. Deep learning models have achieved a par excellence in recognizing images and speeches with models including CNN and RNN.

Latest Trends in Recent Years Within AI-driven applications of healthcare, several developments took place within a span of very less time. From the diagnostics arena, two diagnostic tools made outstanding contributions toward a precise detection of diseases including cancers, diabetic retinopathy, and heart ailments with AI applications such as IBM Watson Health and Google’s Deep Mind Health. AI-based treatment planning systems, including PathAI and Oncora Medical, are the new face of personalized medicine through tailored treatment plans based on an individual patient profile. AI-based telemedicine platforms and virtual health assistants are further improving patient engagement and access to healthcare services.

Challenges and Limitations: Despite the promises of AI in healthcare, many challenges and limitations persist. The lack of transparency and interpretability of AI models is perhaps one of the most significant issues, often labelled as the “black-box” problem. A critical challenge relates to the need for robustness and reliability in AI systems operating in diverse clinical settings. Lastly, ethical issues such as the protection of patients’ privacy and security of their data, bias in algorithms, must be adequately addressed to enhance trust and acceptance of AI among healthcare providers and patients.

APPLICATION OF AI IN HEALTH CARE 

Artificial intelligence has been a game changer in healthcare and has brought forward innovative applications for diagnostics, treatment planning, patient monitoring, drug discovery, and administrative tasks.                 Some of the key applications of AI in healthcare are as follows:

Diagnostics: AI algorithms can analyze medical images (X-rays, MRIs, CT scans) to detect diseases such as cancer, pneumonia, and cardiovascular conditions with high accuracy.                                                                AI-powered diagnostic tools can identify patterns and anomalies in medical data, aiding in early disease detection and improving patient outcomes.

Treatment Planning: AI systems can analyze patient data and recommend personalized treatment plans based on individual patient profiles, ensuring more effective and tailored therapies.                                                   Predictive analytics can forecast patient responses to treatments, enabling healthcare providers to adjust treatment strategies proactively.

Patient Monitoring: With AI-enabled wearable devices and sensors, the patient’s vital signs can be monitored uninterruptedly for abnormal signals in real-time.                                                                                                 AI-powered remote monitoring can intervene promptly, thus reducing the rate of hospital readmission due to alerting the service providers of potential health issues arising.

Drug Discovery: AI optimizes the discovery process of drugs through the evaluation of large data analysis, identifying the candidate drugs, and predicting their efficacy.                                                                      Machine learning algorithms may be used for simulating drug interactions and optimizing chemical structures, saving time and money in discovering new drugs.

Administrative Activities: Artificial intelligence can automate routine administrative activities such as scheduling appointments, managing patient records, and processing insurance claims, thus improving efficiency and reducing administrative burdens.                                                                                                              Natural language processing can assist in the transcription of medical notes and extract information from EHRs, thus smoothing out documentation processes.
