Artificial Intelligence (AI) in healthcare has significantly enhanced our ability to monitor, predict, and respond to health crises. During COVID-19 – a crisis that affected more than 760 million people worldwide, AI provided mission-critical assistance in managing the pandemic, showcasing the capabilities of AI for pandemic preparedness and response.
Despite the significant AI advancements, there is a compelling need to improve AI technologies before the next pandemic. We need systems that can effectively respond to outbreaks in real time. We need to refine AI models, expand data sources, and increase computational power to improve our AI readiness, such as identifying the origin of infectious outbreaks or predicting future pandemics.
Let’s do a detailed discussion on the role of AI in the pandemic and what limitations it can face during future outbreaks.
AI During the COVID-19 Pandemic
Governments and health organizations extensively used AI predictive models to estimate the spread, reproducibility, and trajectory of COVID-19. These models informed public health policies, including targeted lockdowns, social distancing measures, and vaccination campaigns.
AI and healthcare researchers made significant contributions during the pandemic, such as:
- They developed highly accurate AI diagnostic tools to assist in diagnosis via chest X-Ray and CT images.
- These tools enhanced the screening and testing capabilities of health centers while enabling early detection and isolation of infected individuals.
- AI models were used to identify the severity and prognosis of the disease.
- Researchers used AI to assist in drug discovery and vaccine development during COVID-19.
- AI also assisted in identifying existing drugs that were effective against the virus (a process known as drug repurposing).
Such AI initiatives played a crucial role in preventing the collapse of the global health infrastructure during the COVID-19 pandemic.
The Role of AI in Pandemic Preparedness: 5 Major Components
The world witnessed the deadliest healthcare crisis of this century, with more than 6.8 million deaths globally, as of May 2023. In the ongoing economic repercussions caused by this pandemic, the role of AI-based systems, such as robotics, AI chatbots, and predictive analytics, in prevention and management cannot be overstated.
With the ability to process vast amounts of data, detect patterns, and make informed decisions in real-time, AI-powered technologies offer promising solutions to enhance our response to future pandemics. These solutions are:
1. Early Detection & Monitoring Systems
One of the critical aspects of managing viral outbreaks is early detection. And, once the affected regions are marked, they must be monitored 24/7 proactively.
What role can AI play?
- AI analytics can analyze diverse medical data sources, including healthcare records, environmental data, and even social media to identify patterns and detect potential disease outbreaks early.
- AI can assist in identifying potential hotspots by monitoring symptoms, travel patterns, and demographic information, enabling authorities to take timely preventive measures and allocate resources effectively.
2. AI-powered Resource Management: Rapid Response & Resource Allocation
During a pandemic, the allocation of resources is crucial as infectious diseases can quickly overrun the capacity of healthcare systems.
What role can AI play?
- AI-powered systems can optimize resource management by analyzing real-time data on hospital capacity, medical supply inventory, and staffing.
- With this information, healthcare providers can make informed decisions regarding the allocation of beds, ventilators, and medical personnel, ensuring resources are efficiently distributed among the vulnerable population.
- AI can help streamline supply chains by identifying bottlenecks and facilitating the timely procurement and delivery of essential medical supplies.
3. AI Robots & Chatbots: Social Distancing Measures
During a pandemic, any service or process that requires human involvement is severely affected due to forced lockdowns.
What role can AI play in the event of another pandemic?
- AI-powered robots and chatbots can take over routine tasks that involve human contact.
- In healthcare, AI robots can assist in minimizing human contact by performing routine tasks such as disinfection, sample collection, and drug delivery.
- Autonomous robots can be used to deliver food and groceries, as a few instances have been reported already.
- AI chatbots can serve as virtual assistants, delivering reliable information on symptoms, preventive measures, and the latest guidelines from health authorities.
- Chatbots can provide personalized information, triage patients, and reduce the burden on healthcare hotlines.
But these initiatives must be taken on a global scale to facilitate maximum world population. That is where AI pandemic preparedness is tested.
4. AI-Assisted Vaccine Development & Distribution
The rapid development and distribution of vaccines are essential to achieving immunity against pandemics and zoonotic outbreaks.
What role can AI play?
- AI-powered predictive analytics can aid vaccine development by analyzing vast amounts of genetic and clinical data, accelerating the identification of potential vaccine candidates.
- AI can contribute to efficient and equitable vaccine deployment by identifying high-priority areas and streamlining the distribution network.
5. AI-Powered Pandemic Modeling & Forecasting
Data forecasting and modeling can enhance our understanding of public health challenges, enabling proactive measures to improve population health.
What role can AI play in the next pandemic?
- AI-driven prediction models can leverage large datasets, including epidemiology information, population demographics, and environmental variables.
- The outcome of prediction models can inform the decisions made by public health workers and policymakers on a global scale.
- AI models can aid in allocating resources, implementing interventions, and developing effective containment tactics.
AI for Pandemic Preparedness: What are the Major Limitations?
While modern AI systems offer significant potential for pandemic preparedness, several limitations must be addressed.
1. AI Disease Surveillance
AI solutions for the pandemic require rapid response, but AI algorithms built using low-quality data can produce misleading or harmful clinical recommendations. For example, in the US, a lack of accurate racial information in health surveillance databases led to under-reported COVID-19 mortality rates of up to 60% for Black and Hispanic patients. Any AI system built on such data would generate unjust outcomes.
2. Biases in AI Systems
AI algorithms can inherit biases from the training data, leading to discriminatory outcomes in healthcare delivery. Hence, mitigating biases is essential to ensuring success in AI-enabled relief efforts during a pandemic.
3. Data Security & Privacy
People are increasingly embracing wearable technologies and connected health gadgets. These devices generate loads of data that can be sensitive such as personal health data. Often, companies analyze this data to improve their services. As more people interact with the digital world, efforts for privacy protection should be prioritized.
4. Ethical Concerns of AI in Healthcare
When data is involved, ethical issues arise. Regulatory bodies need to provide a global ethical framework around doctor-patient privilege and legal and moral accountability for responsible medical AI adoption. AI implementation should adhere to ethical guidelines, ensuring fairness, transparency, and accountability.
5. Lack of Global Collaboration, Context & Interpretation
AI systems struggle to capture nuanced information, such as cultural practices, social behaviors, and local healthcare infrastructure, which can significantly impact effective response strategies globally. Many decision tools available today are not universally applicable. Also, countries and regions have different data governance policies and data localization laws that can limit collaboration on global data initiatives.
The COVID-19 pandemic has highlighted the significant role of AI in combating wide-scale infectious disease outbreaks. But efforts are needed to scale it globally by building comprehensive and diverse data sources and facilitating data sharing across regions. These initiatives can enable real-time interventions to save lives, protect communities, and build a resilient global healthcare infrastructure. Hopefully, future developments in AI will further enhance our pandemic preparedness.
