In healthcare, there’s no such thing as being too attentive to a patient’s needs — and real-time patient monitoring is here to prove it. Emerging technology and the utilization of real-time data enable medical professionals to monitor a patient’s prognosis quickly and with minimal interruption. The best part is that it enables prompt intervention, allowing medical professionals to take a proactive rather than reactive approach to healthcare. This can make a significant difference in a patient’s outcome.

Today, we’ll walk you through everything you need to know regarding real-time patient monitoring, how inference models play a part, and how immediate care solutions are enabled by both of these.

Understanding Real-Time Patient Monitoring

Real-time patient monitoring involves the utilization of advanced medical devices that enable continuous observation and analysis of a patient’s health data. It differs from patient monitoring of the past by providing immediate care solutions the moment an anomaly is detected.

With real-time patient monitoring, doctors gain access to continuous, instantaneous data. Traditionally, healthcare professionals needed to rely on intermittent readings taken during periodic check-ups, which delayed the detection of critical changes in a patient’s condition.

In contrast, real-time monitoring utilizes advanced technologies like wearable sensors and telemetry systems to provide immediate insights, enabling healthcare providers to respond swiftly to any abnormalities detected.

Another benefit of leveraging real-time patient monitoring is that it reduces hospital readmissions and improves overall patient management. By leveraging real-time data, healthcare providers can make informed decisions more rapidly than ever before.

The Role of Inference Models in Healthcare

To fully comprehend the role inference models play in healthcare, it’s critical to first understand what they are.

An inference model is a form of machine learning model that leverages algorithms to analyze data. From there, it can make predictions or decisions based on that information. In the healthcare industry specifically, these models process real-time patient data to detect patterns, predict potential health issues, and suggest immediate care solutions to healthcare providers.

How Inference Models Work 

Inference models work by applying algorithms to analyze large datasets, deriving meaningful insights that inform decision-making. Typically built using machine learning techniques, these models are trained on historical data to recognize new patterns and correlations. Once trained, they can effectively apply this knowledge to analyze new and incoming data. 

Inference models, crucial for real-time patient monitoring, utilize advanced techniques such as neural networks and deep learning. For more context, check out our AI and machine learning solutions page. 

For real-time patient monitoring, inference models utilize both supervised and unsupervised learning approaches. Supervised learning involves training the model with labeled data, where known outcomes help establish relationships between input data (for instance, a patient’s heart rate, blood pressure) and expected outputs (the likelihood of a heart attack, for example). On the other hand, unsupervised learning enables models to identify patterns and anomalies in unlabeled data, which is critical for detecting unexpected health issues.

Advanced inference models incorporate techniques such as neural networks and deep learning to enhance predictive capabilities significantly. Beyond initial training, these models continuously update their algorithms through online learning as new data arrives. This process guarantees that models stay adaptive and maintain their efficiency. 

What’s an Example of Inference Models in Healthcare?

Imagine you’re a healthcare professional treating a patient with a heart condition. Naturally, you want to mitigate any problems before they arise — so you leverage devices that continuously monitor your patient’s heart rhythm and rate.

These systems typically integrate inference models. These models can analyze the data and predict issues before they arise. Moreover, you can integrate inference models that analyze real-time data alongside historical health information, including genetic predispositions to heart conditions. For instance, if a patient has a family history of heart disease, the monitoring system can adjust its algorithms to be more vigilant, detecting subtle patterns and anomalies that might indicate early signs of potential issues.

The primary purpose of using inference models in healthcare is to predict problems before they arise, making healthcare more efficient.

How Does Real-Time Data Enable the Successful Utilization of Inference Models?

Without real-time data, inference models wouldn’t be as effective. This is because real-time data offers a continuous stream of up-to-date information, which is crucial for making timely, accurate predictions. Without fresh data, inference models cannot detect patterns and anomalies that indicate a patient may experience a health episode soon.

Thanks to real-time data, inference models can process information the moment it is generated, allowing for timely analysis and immediate care solutions. Continuous data flow ensures that inference models are working with the most up-to-date, comprehensive data, increasing the reliability and accuracy of their predictions.

There’s also the aspect of adaptability. With new data continuously fed to your inference model, it can learn and adjust its algorithms in real-time. This ongoing process means that models stay accurate even as patient conditions shift or new health trends emerge.

Real-Time Patient Monitoring Fuels Immediate Care Solutions

In a world without inference models, healthcare systems would not be able to proactively address concerns and take action to mitigate potential problems before they manifest. By leveraging real-time data, healthcare systems can ensure that their inference models remain effective tools for predicting and managing patient health, ultimately leading to better and more personalized care.

Ready to take the next step to get your data where it needs to be? Book a demo today to learn how Striim can help you make data integration and streaming as seamless as possible.

Data pipelines can be tricky business —failed jobs, re-syncs, out-of-memory errors, complex jar dependencies, making them not only messy but often disastrously unreliable. Data teams want to innovate and do awesome things for their company, but they get pulled back into firefighting and negotiating technical debt.

The Power of Declarative Streaming Pipelines

Declarative pipelines allow developers to specify what they want to achieve in concise, expressive code. This approach simplifies the creation, management, and maintenance of data pipelines. With Striim, users can leverage SQL-based configurations to define source connectors, target endpoints, and processing logic, making the entire process intuitive and accessible, all while delivering highly consistent, real-time data applied as merges and append-only change-records.

How Striim pipelines work

Striim pipelines streamline the process of data integration and real-time analytics. A pipeline starts with defining a source, which could be a database, log, or other data stream. Striim supports advanced recovery semantics such as A1P (At Least Once Processing) or E1P (Exactly Once Processing) to ensure data reliability.

You can see the full list of connectors stream supports here. →

The data flows into an output stream, which can be configured to reside in-memory for low-latency operations or be Kafka-based for distributed processing. Continuous queries on these materialized streams allow real-time insights and actions. Windowing functions enable efficient data aggregation over specific timeframes. As the data is processed, it is materialized into downstream targets such as databases or data lakes. Striim ensures data accuracy by performing merges with updates and deletes, maintaining a true and consistent view of the data across all targets.

Here we’ll look at an application that reads data from Stripe, replicates data to BigQuery in real-time, then while the data is in flight, detect declined transactions and send slack alerts in real-time.

Striim’s Stripe Analytics Pipeline

Let’s dive into a practical example showcasing the power and simplicity of Striim’s streaming pipelines. The following is a Stripe analytics application that reads data from Stripe, processes it for fraudulent transactions, and generates alerts.

Application Setup

The first step is to create an application that manages the data streaming process. The `StripeAnalytics` application is designed to handle Stripe data, process fraudulent transactions, and generate alerts.

This statement initializes the `StripeAnalytics` application with an automatic recovery interval of 5 seconds, ensuring resilience and reliability. You can see we define ‘Recovery 5 second interval’. This handles the checkpointing for at least once or exactly once deliver from source to target with transactional support.

Reading from Stripe

Next, we define the source to read data from Stripe. The `StripeReaderSource` reads data at 10-second intervals and outputs it to a stream called `StripeStream`. The ‘automated’ mode denotes that schemas will be propagated to downstream targets (data warehouses, databases), an initial load of historical data will load, before starting the live CDC.

Striim streams are in-memory by default, but can be backed up to our managed Kafka or to your external Confluent Kafka cluster.

Writing to BigQuery

The processed data is then written to BigQuery for storage and analysis. The `BigQueryWriter` takes data from the `StripeStream` and loads it into BigQuery, automatically creating the necessary schemas.

Fraud Detection

To detect fraudulent transactions, we use a jumping window to keep the last two rows for each `customer_id`. This window is defined over a stream called `FraudulentStream`.

A continuous query (`FetchFraudulentTransactions`) is then created to pull declined transactions from the `StripeStream` and insert them into the `FraudulentStream`.

Generating Alerts

To notify the relevant parties about fraudulent transactions, we generate alert events. The `GenerateAlertEvents` query groups the declined transactions by `customer_id` and inserts them into the `FraudulentAlertStream`.

Sending Alerts to Slack

Finally, we create a subscription to send these alerts to a Slack channel. The `FraudulentWebAlertSubscription` uses the `SlackAlertAdapter` to deliver alerts to the specified channel.

Completing the Application

We conclude the application definition with the `END APPLICATION` statement.

Striim’s declarative approach offers several benefits:

1. Simplicity: SQL-based streaming pipelines make it easy to define rich processing logic.

Feature engineering involves creating new variables (features) that can improve the predictive power of the models.

The next phase is model development. Predictive models are developed using various techniques, including regression analysis, time series analysis, and machine learning algorithms such as decision trees, neural networks, and clustering. From there, the models learn from historical data to identify patterns.

In the logistics industry, common predictive models might include demand forecasting models, which predict future product demand based on historical sales data and external factors like seasonal trends, and risk management models, which identify potential supply chain disruptions by analyzing historical incidents and external risk indicators.

From there, the models are validated using a subset of data to ensure they’re capable of accurately predicting outcomes on unseen data. After, models are deployed into production environments where they can process real-time data streams. Continuous monitoring and maintenance are essential to ensure the models remain accurate over time.

As new data becomes available, models may need to be retrained to adapt to changing patterns. This process, referred to as continuous or incremental learning, enables models to adapt to changing patterns, trends, and anomalies in real time.

Lastly, predictive models generate forecasts and risk assessments that business leaders use to inform decision-making processes. Demand predictions enable proactive inventory management, reducing stockouts and overstock situations. Risk predictions allow for preemptive actions to mitigate potential supply chain disruptions.
