Early Results of Using the Digital System on Data Integrity in Lagos, Nigeria

Characteristics	Feature	Result
Completeness and consistency	Form validation	The platform has been able to achieve 100% completeness on all required fields.
Accuracy	Address validation	91% of all addresses (location) entered on the platform were validated. They all contain the state, local government area, and area details; and can be located on Google maps.
	Phone number validation and SMS communications	The platform was able to validate and verify 100% of all phone numbers.
Security and privacy	Strict access control	The platform has strict user access levels that allow us to ensure that only physicians and lab managers have access to test results.
	Data anonymization	To protect the patient's privacy, their data are anonymized for users who do not require them. For example, those who run tests and upload results do not have access to the patients’ personal information.
Timeliness	Real-time data collection and delivery	All data collected are made available on the dashboard in real-time with no delays.
Validity	Duplicate entries restriction	At the launch of the system, the platform received 75% unique submissions. However, after introducing the duplicate entry restriction feature in April 2020, this improved to 79% and by June 2020, we had up to 99% unique submissions.
