Réunion Island, Lockdown, Social Inequalities in Health

['This study was designed and conducted by the clinical investigation center of la Réunion (CIC1410). Phone data collection layed on its survey platform comprising 3 creole-speaking investigators. This platform was reinforced by the enrollment of 2 temporary workers. The database development was done by a datamanager of the team using the Ennov Clinical® software. Data hosting was ISO 9001:2008 certified. Ennov Clinical® integrates its customers' applications in a datacenter located on two mirror sites (Poitiers and Roubaix) offering optimal security conditions. Access to the datacenter is strictly controlled, uninterrupted power supply is guaranteed, weather conditions are controlled and a fire safety system is included (regularly updated and checked). The servers are protected by a firewall and an updated anti-virus system. Customer data is managed in strict compliance with the rules of confidentiality, access is controlled by SSL certificate and all exchanges are encrypted. Ennov Clinical® complies with FDA recommendations regarding "Guidance for computerized systems used in clinical trials", electronic signature (21 CFR Part 11?) and international standards for health data hosting. In the Ré-Conf-ISS study, access to the database was secured (personal identifier and password) with different levels of security depending on the roles assigned to users. The data were entered on the eCRF (CS Online module Ennov Clinical® software) by data entry operators of the CIC. A data entry guide was made available to operators. A data validation plan, jointly defined between the coordinating investigator and the Methodology and Data Management center, was developed and described in detail the controls to be executed for each variable. The quality control of data being entered was exhaustive. Once the entry was made, the consistency of the data was checked, errors, omissions or inconsistencies were mentioned (CS Tests module). The data freeze / thaw process was performed in accordance with the procedure implemented in the Center for Methodology and Data Management.']
