Face-to-face [f2f]
Data Collection Notes
Training of enumerators (known as filed interviewres in Mibita HDSS site) is routinely done before the start of any new round.
This is usually done to familiarize with the system updates on the programme or any additional changes that may seem necessary and necessitate smooth running of the data collection criteria or inform the enumarotors of the anychanges that they may have suggested for the smooth running of data collection process.
- Usually interview may take about 30mins to about 45mins depending on whether there were any additional questionaires added to their routine data collection method.
- Community mobilization and sensitization was first done before data collection at the baseline.
- In addition, more involvement was done to inform community leaders especially the chiefs, leaders and community heads (including policy makers) of the objectives of the HDSS programe.
- The data collection team has usually been conducted by field interviewers (FI) 17 in number guided by immediate supervisors that are named as field interviewer manager (FIM) who are 3 in number.
- Supervisory team comprising of a data manager at the field station and an asdministrator would oversee the whole process and they may seek intervention by community leaders in areas where the community may not seem intrested or refusing to accept enumaration.
- Interview is normally done in local language (Luo) or in Swahili where there find in-migrants.
Questionnaires
The questionnaire is divided into several parts. The 1st part consists of the baseline census dealing mainly with demographic information, such as compounds, household and members. The second part is made up of questions on migrations, health, diseases, causes of death, and other health and hygiene related information.
These processes are repeated to accumulate demographic and health related information for several years.
Data collection in the field uses electronic devices pda.
These devises support field interviewers' data collection activities and execute data consistency checks with regard to questionnaire items on site.
Assumed variables of questionnaire are:
ø information for individual identification
ø demographic information
ø household information
ø migration information
ø pregnancy information
ø health related information
ø vital event information
Collected data is accumulated in the field stations and sent to data management centre in the central office in nairobi, and are subjected to detail-verification check by data managers.
If inconsistent data or unverified data are detected, those data and error codes (or explanation) are sent back to the field.
Verbal Autopsy Questionaires design was made with some modifications but adapted from the recommended WHO questionnaire

Supervision
Enumerators (field interviewers) were organized in teams per working areas and regions which they are assigned to all interviwers!
All enumarators report to a supervisor(field interviewer manager) who is assigned about 6 enumarators and he/she is able to manage them by using an assigned motorbike to move from one working area to the other.
The field interviewer manager (supervisor) roles include the following: coordinate data collection, supplies of equipment and gadgets, coordinating with local authorities, quality assuarance report including checking empty houses/structures, conducting verbal autopsy after the mourning period has passed and following up on skipped houses which may have been skipped by enumarotors if for some reasons owners were absent or only minors were available during the visit.
The data manager at the field station was responsible for the transfer of collected data to our remote server for cleaning before synchronization of the data and backup.
The data manager would go through the quality check reports generated automatically by the system and assignes duties to field interviewer manager based on the results for updates and corrections.
Upper management from the (Nairobi) managing the core data set visited the field once every month and after every round had been completed.
