The adoption of telehealth services has exploded over the past few years, fueled by the COVID-19 pandemic and advancements in technology. With telehealth, patients can conveniently consult with doctors through video chat, phone calls, and messaging without having to visit the clinic or hospital.
According to research from McKinsey, the total annual US spending on telehealth is expected to grow to more than $250 billion after the pandemic, which is a massive increase from $3 billion in 2019.
While telehealth improves accessibility for patients, it also presents new challenges for healthcare providers. Doctors now need to diagnose and treat patients remotely, often without access to vital signs or test results that would be available during an in-person visit. This is where artificial intelligence (AI) and real-time analytics come in.

AI has the potential to augment and enhance nearly every aspect of telehealth:
- Symptom checking - AI chatbots can interview patients to collect information about their symptoms before their telehealth visit. The chatbot can then analyze the symptoms and give recommendations to the patient and highlight potential issues to the doctor ahead of the visit.
- Remote monitoring - Wearables and sensors that connect to smartphones can track key vitals signs and health data like heart rate, blood pressure, blood oxygen levels, etc. AI algorithms can monitor this real-time data to flag any anomalies to the doctors.
- Medical imaging diagnostics - Algorithms can analyze medical images like X-rays, MRIs, and CT scans to detect abnormalities and highlight areas of interest to support doctors in making faster and more accurate diagnoses.
- Documentation and administration - Voice recognition AI can automatically transcribe doctor-patient conversations into medical notes and records. Chatbots and virtual assistants can help with scheduling appointments, prescription refills, billing, and other administrative tasks.
- Triage and referrals - Based on symptoms and medical history, AI can help identify patients in need of urgent care and recommend specialists for certain conditions when a referral is required. This allows doctors to focus on the patients who need them most.
- Precision medicine - Analyzing diverse health data from sensors, medical records, genetics, and more can help AI models personalize diagnosis and treatment for each patient. This is the future of data-driven, personalized medicine.
The benefits here are two-fold. AI augments the capabilities of doctors to improve patient outcomes. It also increases efficiency and allows doctors to handle more patients safely.

Real-Time Data is Key for Effective AI
![](https://assets-global.website-files.com/5ee50f2ef83ac07f0cb7fb44/653a0334186416d03920b395_image-21.png)
To enable the AI applications above, healthcare organizations need access to real-time patient data. Data is the fuel that powers AI algorithms. Without quality data, even the most advanced AI won't reach its full potential.
Here are some of the key real-time data streams that are essential for AI-driven telehealth:
- Video - Recording video interactions creates data that AI can analyze for visual diagnostics and documentation.
- Audio - Transcribing conversations into text documents using speech recognition.
- Vital signs - Temperature, blood pressure, pulse rate, respiratory rate, etc. measured by connected devices.
- Lab tests - Results of blood tests, cultures, biopsies, etc. from external labs.
- Medical imagery - X-rays, MRIs, CT scans, ultrasounds images and associated reports.
- Health history - Electronic health records with medical, family, and prescription history.
- Genomics - Gene sequencing results to enable personalized medicine.
- Behavioral data - Activity tracking and sleep monitoring through wearables.
- Contextual data - Weather, location, traffic, and other real-world information.
- Pharmacy info - Medication adherence and refill data from pharmacies.
The diversity and volume of data required makes integrating all these streams very challenging. Just collecting the data is not enough either. It needs to be normalized, structured, and contextualized so it's useful for downstream analytics and machine learning models.
This requires a real-time data platform capable of ingesting, processing, and analyzing disparate data streams in real-time.

Challenges of Real-Time Analytics in Healthcare
Healthcare organizations have traditionally relied on batch processing and data warehouses for analytics. While these work for billing, regulatory reporting, and hindsight analysis, they fall short in supporting real-time clinical and operational use cases.
Here are some of the challenges faced:
- Data latency - Batch processing introduces delays between data generation and availability for analysis. This hinders real-time use cases.
- Poor analytics performance - Large databases with complex queries lead to slow response times. Unacceptable for real-time monitoring.
- Inflexible costs - Data warehouses require provisioning for peak capacity. The fixed costs are unable to scale up and down with variable workloads.
- Siloed data - Data from IoT devices, EHR systems, labs, pharmacies, etc. is isolated in disparate systems. Provides an incomplete view.
- Skill gaps - Specialized skills needed for data warehousing and traditional analytics restrict developer productivity.
- Compliance risks - Meeting stringent healthcare data compliance requirements like HIPAA is difficult with fragmented analytics systems.
The pieces required to build a real-time analytics solution end up becoming an expensive patchwork of cloud services, databases, and custom integration code. Managing and monitoring all these complex pieces introduces operational burdens for healthcare IT teams.

To overcome these challenges, healthcare organizations need a real-time data platform purpose-built to simplify collecting, processing, analyzing, and acting on data in real-time.
Here are the key capabilities such a platform needs:
- Flexible data ingestion - Should support standard interfaces like REST APIs, database streams, log files, and messaging systems to integrate with existing data sources.
- Real-time processing - Data needs to be processed as soon as it is received with sub-second latency for real-time use.
- Scalable storage - Store and query large volumes of streaming data cost efficiently. Auto-scale capacity up and down.
- Unified analytics - Analyze streaming, historical, and context data together to derive real-time insights.
- Dashboards and alerts - Visual analytics and alerts to monitor healthcare operations and patient health in real-time.
- Portability - Runs equally well on cloud and on-prem. Makes transitioning between environments or adopting hybrid cloud straightforward.
- Security - Fine-grained access controls, encryption, data masking that adhere to healthcare security and compliance regulations.
- Management - Out-of-the-box monitoring, logging, and troubleshooting capabilities to operate the system reliably.
With a purpose-built real-time data platform, healthcare organizations can make the best use of data to increase the quality and efficiency of telehealth services powered by AI.
