Nursing Magazine reported results of a survey of more than 1800 nurses across the country concerning job satisfaction and retention. Nurses from magnet hospitals (hospitals that successfully attract and retain nurses) describe the staffing situation in their units as follows:
|1. Desperately short of help—patient care has suffered||12|
|2. Short, but patient care hasn’t suffered||32|
