Here, data sources include patients’ and caregivers’ conversations, surgical footage, audio, and video recordings of patients.
- Genomic and Biological Data: This data is essential for precision medicines, as it provides insights into patients’ genetic profiles, proteins, metabolite profiles, biomarker data, and DNA/RNA sequencing data.
Real-World Examples & Research Trends
Many studies have been conducted and achieved results that multimodal AI improves diagnostic accuracy compared to single-modal AI.
- According to a report published by the International Institute of Clinical Research and Studies (IICRS), multimodal AI diagnoses give 15-30% higher precision compared to single modality analysis for rare disease diagnosis. Also, it reported a 6–33% performance gain across a large set of 14,324 independent models.
- According to a report published by the Nature Publishing Group, a multimodal approach increases performance accuracy from ~1.2% to 27.7% compared to using a single modality approach.
- A report published by the Nature Publishing Group evaluated that a chatbot-powered multimodal AI system diagnoses eye diseases using text and image input data, generating ~80% more accurate results compared to taking input only in text form.
- According to a report published on ResearchGate, real-time AI dashboards for ICU monitoring and alerting have improved by about 30% compared to prior systems.
- According to a report published by PubMed Central, the median critical alert turnaround time (TAT) to ICU, emergency, and IPD was reduced from 5 minutes to 3 minutes, which represents a 40% reduction in response time for ICU alerts and similar clinical areas.
- An article published by The Economic Times stated that a ~79% reduction of documentation time was achieved by using AI. It can help reduce doctors’ workload by fixing healthcare documentation in India.
Multimodal AI Use Cases in Healthcare
- Streamlined drug development: Multimodal AI in medicine research and development accelerates timelines by improving accurate target identification. Researchers can prioritize viable drug targets and design more effective therapeutic interventions earlier in the development pipeline. Using these models can reduce manufacturing costs, increase success rates, help research teams to generate new molecular structures, and predict drug interactions in a short period of time.
- Personalized and Predictive Care: These AI models track patients’ lifestyle, genetic information, history, and symptoms through wearable, real-time vital monitor devices. These models help forecast disease based on symptoms and create personalized treatment plans for an individual patient.
- Better patient outcomes: Earlier systems only understood one language, but things have changed now with the help of multimodal virtual assistants. Patients can interact in their native language, and these models can understand multiple languages and analyse their biometric inputs, which helps doctors to understand patients and achieve better results easily.
- Higher diagnostic accuracy: While treating a patient, doctors analyse multiple reports, including medical images, text reports, and the patient’s history. This is a time-consuming process. With the help of multimodal machine learning in healthcare, doctors can visualize patients’ health more accurately, diagnose diseases with more precision, and treat in a proper, fast, accurate, and reliable way. These models can help detect complex or rare conditions that single-modality approaches might miss.
- Reduce burden on caregivers: In healthcare, AI has already improved workflow efficiency, and integrating multimodal technology helps healthcare professionals focus on direct patient care. It automates administrative tasks, such as documentation and report generation, and streamlines clinical workflows like ER(Emergency Room) triage optimization and surgical planning.
According to a report published by Oracle Health, multimodal AI systems can reduce documentation workflow by up to 30%, directly reducing the burden on clinicians and enhancing their performance to focus on patients and provide better care.
Challenges and limitations of multimodal AI in healthcare
Data Privacy and Compliance: Data privacy is a significant concern in healthcare. The data used by the multimodal systems is stored in these systems. It is not easy to keep all this diverse data safe, always at high risk of data breaches and cyber attacks. You must follow standards and compliance such as the DPDP Act, GDPR, and HIPAA.
Data integration complexity: Connecting several devices and transferring data among them is a challenging task. Sometimes, seamless integration of these devices, such as EHRs, RIS, LIMS, HIMS, medical claims, pharmacy software, and wearable devices, is quite difficult due to the different formats and standards.
Model bias and reliability: We are still in the early phase of the AI models era. There is a high chance that the system can generate biased output because these systems are still learning. They don’t have data for complex and rare cases. So it’s important to double-check that the output generated is correct
High infrastructure cost: It is expensive to run and maintain a multimodal AI. To run this system, multiple technological resources are included, such as a 5G network, cybersecurity cells, cloud storage, high-power servers, and a GPU. Due to high running and maintenance costs, not every hospital can access this.
Regulatory approvals: The legal sanction processes are complex, costly, and time-consuming. Due to these challenges, small-scale hospitals are afraid to adopt this model.
Role of Synthetic Data in Training Multimodal AI
Synthetic data plays a crucial role in training multimodal generative AI. The data should be of high quality; if the data is biased or incomplete, the multimodal AI models will reflect these shortcomings. Also, it may lead to fairness issues in AI models. Here are a few points on how synthetic data is reshaping multimodal AI:
- Synthetic data enables faster AI model development
