![]() Thus, it represents an attractive option for researchers, governments, non-governmental organizations and others interested in large-scale data collection. Additionally, the use of mobile phones may help to reinforce both clinical and non-clinical processes, leading to improved quality of care and greater efficiency. This class of techniques, known as electronic data capture (EDC) has been shown to be feasible among users with little or no prior experience with data collection or mobile phone use in a number of different settings, provided that they are given some basic training, and has been largely seen as acceptable by managers, users, and data collection subjects. Potential advantages of electronic methods over paper-based methods include lower error rates, reduced likelihood of data loss, higher data completeness, reduced time needed for data collection, feasibility of advanced data quality strategies, and in some cases decreased costs. Mobile phones and personal digital assistants have been used for data collection in developing world settings for over three decades, and have become increasingly common. #Odk destination sign board software#This led us to create and implement an EDC software tool that allows for completely offline data transfer and application updating. However, few tools exist that can be used indefinitely in fully-disconnected settings, where a user will never have access to the internet or a cell network. Many existing EDC mobile software tools are built for occasionally-disconnected settings, allowing a user to collect data while out of range of a cell tower and transmit data to a central server when he/she regains a network connection. This is the case in rural Liberia, where many health workers live and work in areas without any access to cellular connectivity or reliable power. ![]() However, the use of electronic data capture (EDC) through mobile phones is limited in many areas by inconsistent network connectivity and poor access to electricity, which thwart data transmission and device usage. ![]() ![]()
