Implementing electronic data collection platform for household surveys in resource-constrained settings

Abstract

Background In resource-constrained settings, quality and timeliness of data are the main concerns related to the use of information systems for decision making. Many different tools are available to improve such systems, but their usefulness is only been recently explored. In this paper, we describe our implementation of an electronic platform, open data kit (ODK) for data collection and its feasibility in data management for a population-based household health expenditure survey. Methods We evaluated the use of ODK based data collection in households located in two areas (one urban and one rural) in Vellore, Tamil Nadu, India. From each area, we selected a sample of 60 households for piloting the ODK based questionnaires. The household survey questionnaires were programmed using the Microsoft Excel for data collection in the ODK collect android application. The ODK aggregate was used for data storage and data transfer. A team of six field workers was recruited, and trained to use the ODK collect application for survey data collection. After the training, the field workers pilot tested the questionnaires, both in the form of mock surveys and real on-field testing. Results Under mock-interviews, there were no significant differences in time –to completion between the six field workers. A total of 60 households participated in field testing that showed field workers were able to complete the questionnaires in a timely manner, (mean 32 minutes (SD=18)) with minimal errors, and all field workers found the ODK form easy to use. There were no major technical issues in the ODK implementation or with electronic devices. Conclusions Results from both mock interviews and on-field testing of our data collection platform show the feasibility of using this approach in resource-constrained settings. The approach used to implement, integrate, and test this platform can benefit other health researchers in developing settings intending to move from paper-based methods toward electronic data collection systems.

Lessons learned on data collection for a digital health intervention—insights and challenges from Nigeria

“…This is comparable to a study by Bokonda et al 4 in nine developing countries, where they reported the successful use of electronic data collection in health research in about 73% of total usage. Premkumar et al 13 reported a very successful use and implementation of digital data collection in household data collection with no major technical issues, while Maleghemi et al 14 credit the increased surveillance of Acute Flaccid Paralysis (AFP) in South Sudan to the use of electronic data collection method. Generally, when electronic data collection is coded properly, the data quality will always be impressive, especially in terms of data completeness.…”

“…After obtaining consent, face-to-face interviews were conducted using electronic data collection forms created using Open Data Kit (Premkumar et al 2021). On recruitment, households were only interviewed about the baseline sociodemographic characteristics, wealth status, self-reported health status, and presence of any major chronic disease conditions.…”

“…A structured questionnaire was developed using Open Data Kit (ODK) tool through an excel sheet. ODK is an electronic platform for data collection which works both online and offline, easy to use and involves no major technical issues [13]. Questions were divided into modules, and responses were stored in Google drive.…”
