The role of medical generalism in the New Zealand health system into the future.

New Zealand hospitals are facing medical workforce shortages and an ageing population with increasing multimorbidity. To be sustainable in the future, the future medical workforce will need expertise in dealing with the complexity of people living with multiple physical and mental health issues. This will require a greater focus on generalism within the speciality colleges, and generalist doctors within the hospital settings, as well as their traditional home of community settings. Doctors' career choices will need to be matched to changing community need. The Transalpine Health Services generalist, specialist and sub-specialist workforce model developed by the West Coast and Canterbury health systems points the way to future sustainable provision of a quality patient hospital experience as close to home as possible, for people who live in provincial New Zealand, through a regional network approach. System-wide changes are suggested to support a more balanced future medical workforce. These include greater valuing of careers in generalism, aligning of incentives to promote medical careers based in generalism, developing regional networks that cross existing District Health Board boundaries to provide patient care, and application of system outcome metrics that measure quality of care and patient outcomes in an integrated health system.
