monthly expenditure of the health workers on mobile top‐up cards broken down by money spent on
voice, data and SMS. Interestingly, the number of SMSs sent by HEWs and midwives was very low. doi:

Input from the health workers was critical in the development of the protocol forms,
which questions should be asked and clarifying any misunderstanding and
ambiguities in the questions and response options. After producing an initial draft of
the protocols, we made several revisions of each protocol form and its questions, based
on input from the health workers and analysis of how they were using the forms for
practice data entry. These iterations allowed us to identify potential problems before
starting to collect data on real patients.
In using ODK for gathering information over an extended period of time, with different
forms completed at different times, we are essentially forcing ODK to do something it
was not designed for. Although ODK assigns a unique identification number to each
form submitted, there is not a built‐in way to link different form instances, either of
the same or different form types, submitted at different times, which is required for
gathering longitudinal information, hence we used the patient id to match up forms.
Since the patient records were not permanently on the phones, we were depending on
