The CHAP accreditation process was established to provide an objective, external process for evaluating an organization's effectiveness in meeting its own mission, while the organization was providing services that meet national care standards. The entire CHAP review process is based on a nursing model of care--that of organizational assessment, strength and weakness identification, appropriate organizational interventions, and evaluation that provides a holistic approach to an organization's performance. CHAP expects to see a home care or hospice organization providing effective services that are appropriate for the patient population and communities it serves.
