For the County to achieve the goal and objectives set out in County Health Sector Strategic Plan (CHSSIP) 2018 - 2023, a robust and efficient HIS/ M&E system is crucial. It is with this backdrop that the sector through the stewardship of the County Department of Health and Sanitation sought to bring all stakeholders in health together to forge a common course for M&E. The purpose of the M&E Plan is to steward the sector towards establishing one M&E system for improved accountability in health at all levels. The sector has made notable investments in strengthening the routine reporting system to make it more responsive and useful for sector performance monitoring. The Department has shown increased commitment to a single unified HIS by developing or adopting key HIS/ M&E policies. New technologies, realigning to UHC, measurement priorities, and national commitments to strengthening HIS present a major opportunity. HIS subsystems including TIBU (Program Management System for Tuberculosis), Community AIDS Program Reporting (CAPR), Logistics Management Information System (LMIS), Community Health Information System (CHIS), and Integrated Disease Surveillance and Response (IDSR) are now integrated into DHIS2 making it the default routine reporting system.
