In the long term EDC is likely to be cheaper (as skills in form development increase, and hardware costs are written off), and perceived higher data quality makes it justifiable (9).
The increase in the availability of bandwidth for wireless links, network integration, and the computational power on fixed and mobile platforms at affordable costs allows nowadays for the handling of audio and video data, their quality making them suitable for medical application.
The databases contain valuable information and improvements in data quality would make them even more useful.
A scoring metric allows for direct comparison of data quantity and data quality, and makes transparent the effort made by different sensor operators.
For policy makers and researchers, it is also crucial to check the data quality before making policy measures or conducting their own research.
This area is particularly challenging because of the difficulty of controlling these multisensory stimuli, and in the case of human neuroimaging, maintaining data quality while making movements.
Although data quality checks have been made on incoming data over the years, and feedback provided to the data suppliers, the WDC is ultimately a depository.
Regardless the PMU data quality issue, to make these methods applicable in practice, the detection accuracy of arrival time, the impact from the non-constant wave speed throughout the network and the adaptability to different network topologies should be first investigated and guaranteed.
Thirdly, publication bias is likely to impact the evidence-base of P4P effectiveness and data quality bias may make the comparison of results across P4P programs problematic[ 140].
Putting the reproductive health needs and priorities of adolescents at the heart of efforts to strengthen health systems, promoting equitable access to services and improving data quality will help make the end of preventable maternal mortality a reality.
