exercises. This training involved three visits to a daycare center that New ERA had organized. The
biomarker training included measurement of hemoglobin levels in women age 15–49 and children age 6–
59 months through collection of capillary blood. Blood pressure measurements were taken for adults age15
and above.
A separate session was held for the supervisors and the quality control teams on December 17 and
December 23, 2021, to provide training on fieldwork management and data quality monitoring. These
sessions included discussions on roles and responsibilities, preparation and mobilization for fieldwork,
managing assignments for biomarker specialists and facilitating remeasurements, completing biomarker
checklists, conducting re-interviews in CAPI, and monitoring the progress and workload of team members.
On completion of the training, field practice was carried out in Chandranigahapur, in the terai ecological
zone, about 100 miles from Kathmandu City, where all three languages could be practiced. The teams
departed on December 24, 2021, and the field practice was carried out from December 25 to December 28,
2021. Nineteen teams, consisting of a supervisor, one male interviewer, three female interviewers, and one
biomarker specialist carried out the field practice. A review session was held on December 29, 2021, to
discuss the experience and feedback from the field practice. Overall, it was a fruitful exercise whereby the
teams could experience real field conditions and be prepared before being mobilized for the actual data
collection.
2.6 FIELDWORK
Data collection for the 2022 NDHS was carried out by 19 teams. Each team consisted of a supervisor, one
male interviewer, three female interviewers, and one biomarker specialist. The teams were first deployed
in locations away from Kathmandu because at that time the capital city was a COVID-19 hotspot. The
fieldwork began on January 5, 2022, in two central locations—Itahari and Chitwan—under close
supervision. On completion of the fieldwork in these first locations, a review session was held on January
9, 2022, and the teams departed to their respective assigned clusters on January 10, 2022, to continue with
data collection for the survey. Caution was taken while mobilizing the teams throughout the data collection
period to mitigate the risk of COVID-19. Except for few mild cases, there were no major impacts of
COVID-19 during data collection. The fieldwork was slightly disrupted when local elections took place.
The field teams had to go home to cast their votes, and the local people were engaged in election activities.
Data collection activities were completed on June 22, 2022.
Fieldwork monitoring was an integral part of the 2022 NDHS, and several rounds of monitoring were
carried out by the New ERA core team and quality control teams. ICF provided technical assistance during
the data collection period through weekly virtual meetings. The technical teams from the Ministry of
Health and Population, Nepal Health Research Council, and USAID Nepal made several field visits to
ensure data collection was carried according to the protocol. Regular feedback was provided to the teams
by the New ERA core team.
2.7 DATA PROCESSING
Data capture for the 2022 NDHS was carried out with Microsoft Surface Go 2 tablets running Windows
10.1. Software was prepared for the survey using the Census and Survey Processing System (CSPro). The
processing of the 2022 NDHS data began shortly after the fieldwork started. When data collection was
completed in each cluster, the electronic data files were transferred via the internet file streaming system
(IFSS) to the New ERA central office in Kathmandu. The data files were registered and checked for
inconsistencies, incompleteness, and outliers. Errors and inconsistencies were immediately communicated
to the field teams for review so those problems would be mitigated going forward. Secondary editing,
carried out in the central office at New ERA, involved resolving inconsistencies and coding the open-
ended questions. The New ERA senior data processor coordinated the exercise at the central office. The
NDHS core team members assisted with the secondary editing. The paper Biomarker Questionnaires were
compared with the electronic data file to check for any inconsistencies in data entry. The pictures of
