While vulnerable populations are most susceptible to lack of health care and inadequate services, all consumers are potentially at risk. Social workers and front line health care workers can help solve these problems, but effective advocacy is a learned skill. Best-selling author and award-winning researcher Bruce Janssen uses an intervention framework and first-person case studies from a variety of health care workers and consumers to illustrate how everyone in the health care system can advocate effectively not just for individual clients, but for policy change as well.
