Using national surveys, administrative data, and nearly 120 original interviews with workers, employers, advocates, and policymakers, Osterman finds that direct care workers are marginalized and often invisible in the health care system. While doctors and families alike agree that good home care aides and CNAs are crucial to the well-being of their patients, the workers report poverty-level wages, erratic schedules, exclusion from care teams, and frequent incidences of physical injury on the job. Direct care workers are also highly constrained by policies that specify what they are allowed to do on the job, and in some states are even prevented from simple tasks such as administering eye drops.

Osterman concludes that broadening the scope of care workers' duties will simultaneously boost the quality of care for patients and lead to better jobs and higher wages. He proposes integrating home care aides and CNAs into larger medical teams and training them as "health coaches" who educate patients on concerns such as managing chronic conditions and transitioning out of hospitals. Osterman shows that restructuring direct care workers' jobs, and providing the appropriate training, could lower health spending in the long term by reducing unnecessary emergency room and hospital visits, limiting the use of nursing homes, and lowering the rate of turnover among care workers.

As the Baby Boom generation ages, Who Will Care for Us? demonstrates the importance of restructuring the long-term care industry and establishing a new relationship between direct care workers, patients, and the medical system.
