I am a physician. These two areas of health care are the most underserviced in our current system. Improvement to delivery systems, new models of care, community based care, targeted for these groups, will benefit all areas of health care, especially wait times everywhere. That is because the bulk of the inefficiencies in our current system arises from failure to address the deserving needs of those with mental illness and addictions, and those people with chronic diseases and disabilities who prefer to remain in their own homes than in much more expensive institutional care. All these people, while needlessly suffering, (multiply them by the number affected in their families) are derided for clogging up hospitals. They do but because we ignore their health needs; they are poor, second class citizens in health care. A hospital bed costs $1500/day (and still not enough staff to talk to patients/families). It is cheaper and more effective to fix/stabilize earlier in community.  Do it!!
