MedicalResearch.com: What is the background for this study?
Response: The idea that adding lower skilled and lower wage caregivers to hospitals instead of increasing the number of professional nurses could save money without adversely affecting care outcomes is intuitively appealing to mangers and policymakers but evidence is lacking on whether this strategy is safe or saves money.

Medical Research: What is the background for this study?
Response: We wanted to test whether hospitals with better nursing work environments displayed better outcomes and value than those with worse nursing environments, and to determine whether these results depended on how sick patients were when first admitted to the hospital.
Medical Research: What are the main findings?
Response: Hospitals with better nursing work environments (defined by Magnet status), and staffing that was above average (a nurse-to-bed ratio greater than or equal to 1), had lower mortality than those hospitals with worse nursing environments and below average staffing levels. The mortality rate in Medicare patients undergoing general surgery was 4.8% in the hospitals with the better nursing environments versus 5.8% in those hospitals with worse nursing environments. Furthermore, cost per patient was similar. We found that better nursing environments were also associated with lower need to use the Intensive Care Unit. The greatest mortality benefit occurred in patients in the highest risk groups.
