The Massachusetts General Care Management Program (Mass General CMP or CMP) was designed as a federally supported demonstration to test the impact of intensive, practice-based care management on high-cost Medicare fee-for-service (FFS) beneficiaries-primarily older persons-with multiple hospitalisations and multiple chronic conditions. The Massachusetts General Care Management Program operated over a 6-year period in two phases (3 years each). It started during the first phase at Massachusetts General Hospital, a major academic medical centre in Boston, Massachusetts in collaboration with Massachusetts General Physicians Organisation. During the second phase, the programme expanded to two more affiliated sites in and around the Boston area, including a community hospital, as well as incorporated several modifications primarily focused on the management of transitions to post-acute care in skilled nursing facilities. At the close of the demonstration in July 2012, Mass General Massachusetts General Care Management Program became a component of a new Pioneer accountable care organisation (ACO). The Massachusetts General Care Management Program is focused on individuals meeting defined eligibility criteria who are offered care that is integrated by a case manager embedded in a primary care practice. The demonstration project showed substantial cost savings compared to fee-for-service patients served in the traditional Medicare system but no impact on hospital readmissions. The Massachusetts General Care Management Program does not rest upon a "whole systems" approach to integrated care. It is an excellent example of how an innovative care co-ordination programme can be implemented in an existing health-care organisation without making fundamental changes in its underlying structure or the way in which direct patient care services are paid for. The accountable care organisation version of the Massachusetts General Care Management Program includes the staffing structure, standards of practice, collaborative approach to care transitions and information technology tools that were used in the original demonstration project.
