Background: The Health Information System (HIS) is a set of computerized tools for the collection, storage, management, and transmission of health data. The role of such tools in supporting the modernization of health systems, improving access to quality healthcare, and reducing costs in developing countries is unquestionable, but their implementation faces several challenges. In Gabon, a unique national electronic HIS has been launched. It will connect healthcare institutions and providers at all levels in the whole country., Objective: This study aims to explore and identify the factors influencing healthcare providers' perceptions of the national electronic HIS in Gabon., Methods: A 44-item questionnaire based on the Information System Success Model (ISSM) was administered between February and April 2018 among 2600 healthcare providers across the country. The questions assessed the different aspects of the HIS that could influence its perceived impact on a 5-level Likert scale (from fully agree to totally disagree). The reliability and construct validity of the questionnaire were checked using Cronbach alpha and congeneric reliability coefficients. A logistic regression was used to identify the factors influencing healthcare providers' perceptions of the system., Results: A total of 2327 questionnaires were completed (i.e. 89.5% response rate). The logistic regression identified five elements that significantly influenced perceived system impact: System Quality (Odds Ratio-OR = 1.70), Information Quality (OR = 1.69), Actual Use (OR = 1.41), Support Quality (OR = 1.37), and Useful Functions (OR = 1.14). The model explained 30% of the variance in providers' perception that the national HIS leads to positive impacts., Discussion: The results show that healthcare providers' perceptions regarding the positive impact of the national HIS in Gabon are influenced by their previous use of an HIS, the scope of their usage, and the quality of the system, information, and support provided to users. These results could inform the development of strategies to ensure adequate change of management and user experience for the implementation of the national HIS in Gabon, and eventually in other low resource environments.

Objective: The need for an efficient and reliable health information system motivated Gabon, with the support of the World Bank, to finance a project to reinforce its health information system. An audit of this system was required to report on the reality of the existing system and tools., Methods: Over the course of two periods, May to September 2016 and April to May 2018, information was collected using both qualitative and quantitative approaches. In this framework, were carried out successively: participative workshops including health actors in Gabon, a survey of health care workers, an analysis of reference documents relating to national health policies, and an analysis of the strengths, weaknesses, opportunities, and threats to the system., Results: In total, 171 health care professionals participated in the different workshops, and 770 others were questioned among 150 health care establishments from 10 health care regions of the country. At the end of this research work, organizational and technical problems were noted at the level of the health information system of Gabon, notably the absence of a judicial framework defining the roles and responsibilities of the different actors of the system, weak data management, a stovepipe information system, several non-interoperable IT applications, and weak completeness rate, at 30%. Among the 770 health care professionals surveyed, 539 (70%) were favorable to a new information system. As for the main assets, we noted the existence of computing equipment and acceptable internet coverage, 31.5% of the health care establishments are connected via cable., Conclusion: This research sheds light on the existing health information system and should enable the implementation of a new system.
