AJN's Annual Year in Review: 2010: Editor's note: Each January AJN examines the major stories affecting nurses and health care during the previous year. This past year was dominated by stories about health and health care: health insurance, health reform, the mental health problems of soldiers returning from combat, and the sustainability of Medicare and Medicaid. Diabetes and obesity, along with smoking, are still the major focuses for disease prevention efforts. The nursing shortage abated with the poor economy, which gave states some time to develop and implement strategies to increase workforce capacity. And at year's end, the Institute of Medicine threw its considerable weight behind nursing as a key to health reform.
