This manual has been developed to support the provincial programme managers, district programme managers, PHC supervisors, local area managers and PHC facility managers in improving the quality of PHC services rendered through the implementation of the ICDM and in ensuring sustainability of the ICDM. The manual is written as a step-by-step guide, although many aspects of the implementation may occur simultaneously. The manual aims to assist facility operational managers in ensuring compliance and in implementing the six priority areas of the National Core Quality Standards for Health Establishments, namely improving staff values and attitudes, waiting times, cleanliness, patient safety and security, infection prevention and control, and the availability of medicines and supplies. This manual provides a step-by-step guide for the implementation of ICDM by facilities without external service provider support. This comprehensive user manual has been developed to support health service ownership, accountability and sustainability in the implementation of the ICDM model. In addition, it aims to foster a common understanding and strong team work in the provision of quality services to patients with all chronic illnesses.
