Flowchart for creating a community health worker (CHW) mobile phone follow-up request. If a patient complaint (illness or pregnancy-related) was not resolved at the clinic, a referral to a higher level of care or a follow-up clinic appointment could be scheduled. For those patients who had initial clinic visits that met the criteria for severity, a potential CHW follow-up was generated by the software. If a patient then missed the return clinic appointment or had been referred to a higher-level facility, a short-term additional window was then given for the patient to return to the clinic. If the patient did not return to the clinic in this window, the follow-up request was then released to the CHW mobile phone.
