If you are a doctor, you can log into a patient’s file and instantly see trends over days or weeks. You could notice if a patient's heart rate has been unusually high over the past couple of days. This integration allows you to make better-informed decisions quickly, without waiting for the patient to come in for a visit.

Smart pill bottles are another exciting component. They track medication adherence and can flag missed doses. With an integrated EHR, these alerts are recorded straight into the patient’s medical history. 

Let’s say a patient frequently misses their evening dose. This information is right there, part of the record, giving healthcare providers a comprehensive view of the patient’s adherence patterns. 

In hospitals, the integration of IoMT with EHR can transform patient care. Consider mobile imaging devices. These devices capture diagnostic images and upload them directly to EHRs in real time. 

So, when an MRI is done, there's no waiting for scans to be manually entered into the system. Specialists can access these images immediately, regardless of where they are, and begin assessing a patient’s condition. It's like having a digital expressway connecting diagnostic tools directly to patient files.

Even smart beds contribute significantly here. These beds monitor a patient’s movement and vital signs and can send this data right to their EHR. So, for a patient with fluctuating blood pressure, the bed captures this variance and updates it into the record continuously. 

Medical staff can then access this information, providing insights into the patient’s condition without needing to hover over monitors constantly. It’s practically like having a continuous health diary being written directly into the patient’s file.

The integration of IoMT with EHR is all about making healthcare more efficient, accurate, and timely. It turns isolated data points into a comprehensive health narrative, allowing both everyday observations from smart devices and critical medical insights to coexist and enrich the patient’s health record.
