I am currently working on a project and which requires collecting patient information from the field and provide them a barcoded referral form. When the referred patient will visit the health centre for test, we need to scan the barcode and autofill with the information of that patient and them update the form with some additional information. I know there are some existing documentation. However, I am quite confused about the whole process. Some simple stepped instruction may help me a lot to move forward.

Another quick question is there any way of using my home printer instead of zebra for test purpose for the time being? -mobile-bluetooth-printer-ios-compatible-3-wide-m3i-0ub00010-00-1/ is it the right Zebra printer?

As @Trung says, you can build and print the code any way you want. For example you could use something like -generator.org/. The Zebra printer is if you want to use the form to collect data and print a code from it. For example @Mic has a form for registering participants and prints name badges for them.

What I would do in your case is create a CSV with the first column being the ID that will be in the code and then the next columns for whatever data you need preloaded. Then you can use pulldata to look up the id from the code and populate the corresponding fields in your form. See -loading-csv-data for documentation on pulling data from CSVs.

Edit: it seems you do want to also print a code on the initial encounter. The printers supported by the Zebra print drivers are at -series.html. So yes, the one you linked to would work. You could also use a computer and regular printer since you'll most likely want to encode just an ID.

Thanks a lot for your guidance. However, it's just me take some time to understand things. I have tried preloading the example forms and tried to follow the instructions. Now I have few questions as the following:

I am a little confused about some basic things. Can I include multiple information in a barcode? Does a barcode represent set of information or just a code? If it's just a code, how do I know, who is appearing for test. For example, the field workers referred 4 (W,X,Y and Z) suspects for the day. By scanning the code, how do I know, who appeared for a screening?

@Trung's idea of having pre-printed barcodes with unique identifiers is a really interesting one that could dramatically simplify the workflow depending on your needs. For example, the first form could ask for id, name, contact_number, etc and to scan the pre-created barcode that the patient will be given. That would associate the random unique ID in the barcode with the patient.

At the health facility the form could then ask for barcode scan and test results. Then the information could be linked through the unique ID from the barcode by someone doing data analysis. This is a simple system that plays well to ODK's strengths and works entirely offline.

The downside is that name/contact_number/DOB/etc won't be verified at the health facility. If that is necessary, then you could encode the information in the barcode and print it from the intake form using a Zebra printer. You could then read that from the health facility and ask the patient to confirm each field and give them an opportunity to update the info if needed.

To directly answer your questions. You can include quite a bit of information in a QR code but encoding just a unique identifier could lead to a simpler workflow. You would then use that unique identifier to link the health facility record to the patient info record.

Thanks so much for all the information you have provided so far. In fact, I need to go for option 2: include name/contact_number/DOB etc in a QR code and print that using Zebra printer and once the referred suspect will appear at the health centre, retrieve patient information using the unique identifier to link the health facility record to the patient info record.

Is there any example guideline or example form available to include few columns of data into a QR code and print them and guideline and example form for the health facility to scan the QR code and retrieve patient information. One thing I would like to mention here: the referred person is not pre-registered at the health facility record. I need to scan the QR code and view the information on screen and input result.

Hi @LN, thanks for your comment. I agree with most of your points, except for the quoted one. Maybe I haven't fully got it, but I don't see that it's necessarily has the downside. There are a few things to note:

I am attaching a form mockup we have used developed for a traceability use case FYI (I'm sorry for the labels in Vietnamese, but the one I highlighted is in English for your information).

Here is a sample intake form. It asks for some identifying information and then sends that to be printed as a QR code. I don't have access to a Zebra printer so I can't verify the barcode but I believe I did it right (hah! I hope so at least!).

Note that I'm kind of abusing selected-at in order to separate out the different fields. Using select-at means the QR code must contain space-separated values which also means the values themselves can't contain spaces. If that's a problem we can explore some alternatives.

Handing out pre-printed codes is simpler and less likely to fail. It doesn't sound like you're collecting much patient data so you could just have both the intake and the health facility forms ask for the info and verify that the records match later. Remember that they will be linked by the QR code identifier. This is common -- even in the US I seem to have to fill out the same info every time I see a health provider. And on a piece of paper, too!

Thanks so much, this is exactly something I was looking for. This is a complete solution to move forward. Of course, it's my turn now to make it better. And for this case, I will keep posting my real life experiences here, so that others can also learn.

If I collect data using this method at the field level for the suspected patients. Once they will come to the facility for a screening test, a receptionist will screen the QR code and enter the test results once the test has been performed. Here I have another issue: I need to make sure that the person has been referred for a test, appeared at the health facility for a test. How do I link two entries? Instead if using two different forms, I am using one form for referral and for the health facility. Please see the attached form active_case_finding.xlsx (16.8 KB)

One thing you could do is introduce a calculate field with uuid() in the calculation column for the first form. This will generate a unique identifier. You could include that in the barcode and read it like you do the other fields from the second form. That will let you connect the two records on analysis.

I Also dont understand where the issue is exactly...

ODK is for collecting the data, the unique identifier links them...

And then you have an analytic program that helps you filtering, manupulating, fusing, making nice graphics.

So an Example how it can be done:

For a Community Center we register the participating children with the form that i attached.

It generates a barcode consisting of an ID and a random Badge Number that are written in a Barcode. You can compose whatever string you like in the barcode.

Then the registration Data is in the Database and the barcode is unique.

Then in the analytic program, in our Case PowerBI (i really suggest this one :)) we have a filter mask to search for a participant and see which events she/he visited.

If you are looking for a printer... Zebra MZ220 is generally working but from time to time it loses connection to the device and the device must be restarted.

For an Acer ZEST Plus this happens quite often...

For an Acer Iconia tab 10 its much more stable.

I think the crashes are a memory overflow or something in the printer driver. Depending on your use you should invest a bit more in the Android device

Your supports were really helpful and exactly what I was looking for to identify the participation of the TB suspects registered using my form. In my case I combined both forms (example forms created by Hlne for me) and added an option at the beginning, so that I can use the same form for data collection and to include results of the TB suspects have been referred for screening. The reason I combined both forms to ensure that I can see both entries on the same page and to identify the number of suspects turned up for screening and number of suspects are missing.
