The study is planned in two parts: Part A will be a simultaneous control study occurring in the "transition" period comparing endpoints in those health establishments with e-Chasqui access to those in matched health establishments without e-Chasqui access. Part B will be an historical control study comparing endpoints in the establishments which gain initial e-Chasqui access, before (historical control) and after (intervention) the implementation. Data sources include: patient charts, interview with health providers to confirm or clarify accuracy of data in patient charts, microbiology registries at local, regional and national laboratories, and the information system database. The total number of subjects to be enrolled study-wide is 1849.
