Table 1.

Information collected from callers.

Introductory block	Allowed the interviewer to introduce her/himself and ask the caller to answer questions with as much information as possible, noting that every detail helped to locate the loved one in the records. Confidentiality was also addressed.
Block A (A1–A3)	Collected information about the caller: address and phone numbers and a phone number for an additional contact person (substitute).
Block B (B1–B13)	Demographic information about the loved one: his/her address, phone number, occupation, and a name of the head of the household. If the loved one was under 15 years old, additional questions were asked about the mother and father of the child.
Block C (C1–C5)	Inquired about the time of death and circumstances before death of the loved one.
Blocks D–F are asked depending on responses to the questions in Block C
Block D (D1–D3, loved one passed away at home)	Asked if the deceased was picked up by ambulance and if the family had any records left by the district surveillance officer or burial team member.
Block E (E1–E3, loved one passed away in a medical facility)	Name of the medical facility.
Block F (F1–F2, loved one was alive when transported by the ambulance from home)	Name of the medical facility where the loved one was taken.
Conclusion block	Gave an opportunity to the caller to provide any additional information and to ask questions. The interviewer also informed the caller that sometimes the information the family seeks cannot be found or does not exist but regardless, the project team would call back to inform them about the results of the search.
