Background: In the 21st century, one of the key elements for providing quality services in healthcare institutions is undoubtedly "knowledge management". Knowledge management is crucial for overall management in any organization given its advantages in terms of competitiveness and productivity. Aim: To analyze the perception of healthcare professionals about the processes of knowledge management at hospitals and the advantages of using such processes as a tool to improve the quality of healthcare services in Haiti. Methods: To achieve that goal, a questionnaire was administered to a total of 295 healthcare professionals in three renowned hospitals located in Port-au-Prince, the capital city of Haiti. Correlation, regression, t-test, and Anova analyses are used. Results: It is observed that most of the participants think that the storage of knowledge is very useful in hospitals while they believe that the use of information collected through knowledge management is currently less beneficial in their daily activities. There is poor correlation between knowledge management processes and perception of health professionals on the benefits of the use of hospital information systems, Conclusions: Health information systems are still dependent on tools such as written documents, some computer hardware tools, and office programs in Haiti. So it doesn't provide clinical, administrative and decision support to health professionals because of the lack of integrated systems in Haiti.
