Established in 1989 as one of the first centers to scale up rigorous research on the impact of nursing on patient outcomes, the Center uses evidence to inform policy and produces the next generation of scientists.

Ischemic stroke patients spend less time in the hospital and are less likely to be readmitted when the hospital has better nurse work environments.

Margo Brooks Carthon, PhD, RN, FAAN, Associate Professor of Nursing and co-author..In a new study from the Center for Health Outcomes and Policy Research (CHOPR), researchers evaluated the association between the nurse work environment and readmission and length of stay for close to 200,000 hospitalized adult ischemic stroke patients in more than 500 hospitals. They found that in hospitals with better nurse work environments, ischemic stroke patients experienced lower odds of 7‐ and 30‐day readmissions and lower lengths of stay.

Their research has been published in the journal Research in Nursing & Health. The article “Better Nurse Work Environments Associated with Fewer Readmissions and Shorter Length of Stay Among Adults with Ischemic Stroke: A Cross‐Sectional Analysis of United States Hospitals” is available online.

“The work environment is a modifiable feature of hospitals that should be considered when providing comprehensive stroke care and improving post‐stroke outcomes,” says Heather Brom, PhD, RN, NP-C, lecturer at Penn Nursing and lead author of the article. “Our findings have important implications for quality improvement initiatives for stroke care management.”

Closing the Racial Disparity Gap in Survival After In-Hospital Cardiac Arrest

In-hospital cardiac arrests (IHCA) represent catastrophic and often terminal events. Despite investments to improve the quality of resuscitation efforts, fewer than 25 percent of all patients that experience cardiac arrests in hospitals survive to discharge, and survival varies significantly across hospitals and by race. Until now, few have been able to specify reasons for the between-hospital differences. More

“The effect of being cared for in hospitals with better medical-surgical staffing has a greater effect on black patients than white patients, and differences in survival to discharge after an IHCA between black and white patients are more pronounced in poorly staffed hospitals than in well-staffed hospitals.”

According to a new study published in Medical Care, improving hospital nurse staffing as proposed in pending legislation in New York state would likely save lives. The cost of improving nurse staffing would be offset by savings achieved by reducing hospital readmissions and length of hospital stays. More

The study was carried out by the Center for Health Outcomes and Policy Research, University of Pennsylvania School of Nursing in partnership with the National Council of State Boards of Nursing. Funding for the study was from the National Council of State Boards of Nursing, the National Institute of Nursing Research/NIH, and the Leonard Davis Institute of Health Economics at the University of Pennsylvania.
