Schema/module for storing test results from medical devices

[Rakshit Wadhwa]

Greetings!

We are building a system in which the data is taken directly from medical devices such as pulse-oximeter, ecg etc, and shall be stored in a repository along with the patients' information. Since, the data can be just a unique number like heart rate, or temporal data which changes extremely frequently within a reading such as ECG or any other combination. What is the advised schema for such a use case? Shall we store this data under a field say results, which can have key value pairs which in which a value can be anything like text, number(like heart rate), image(for ECG, and similar results) etc, as various keys will have their own type of values, or we shall adhere to some other structure.

Also, if some module already exist which can cater our needs, then it will be great to know.

We are actually new to OpenMRS,and any kind of help is appreciated.

Thanks and regards!

Roger, what implications does this have for the information model and the concept dictionary. It would seem that storing these results as complex ops would still require concept tagging. For vitals, passing a SBP, DBP, Pulse from the device to three numeric concepts would be easy. Recording an ECG is another matter entirely (although there is a concept for ECG, but the results are only the qualified metadata such as "normal, atrial fibrillation, etc."

Andy, I didn't really think about that, I haven't looked at the protocol in quite a while.  I mostly wanted Rakshit Wadhwa to think in terms of designing the module as a protocol handler configurable for particular devices rather than pulse oximeter module.
