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.

Hospitals with More Inpatient Nurse Practitioners Linked to Better Outcomes, More Satisfied Patients

According to a new study published in the prestigious Medical Care, hospitals that employ more inpatient nurse practitioners have lower surgical mortality, higher patient satisfaction, and lower costs of care. Nurse practitioners are registered nurses with advanced graduate education and expanded legal scope of practice to prescribe treatments including pain medications. 

“This is the first large study to document the significant added value of hospitals employing nurse practitioners in acute inpatient hospital care as well as having good RN staffing,” said lead author Professor Linda Aiken, PhD, RN of Penn’s Center for Health Outcomes and Policy Research and the Leonard Davis Institute of Health Economics.

“This important study shows that nurse practitioners enhance hospitals’ success achieving clinical excellence, patient satisfaction, and lower per patient expenditures while also contributing positively to overall clinician wellbeing during challenging times,” said co-author Regina Cunningham, PhD, RN, Chief Executive Officer of the Hospital of the University of Pennsylvania. ”

Safe Nurse Staffing Standards in Hospitals Saves Lives and Lowers Costs

A new study published in The Lancet Global Health showed that establishing safe nurse staffing standards in hospitals in Chile could save lives, prevent readmissions, shorten hospital stays, and reduce costs.

July 6, 2021 | The study, by the Center for Health Outcomes and Policy Research (CHOPR) at the University of Pennsylvania School of Nursing, and the Universidad de los Andes - Chile School of Nursing, found very large variations in patient to nurse staffing across 40 hospitals located throughout Chile. Nurse staffing was significantly better in private compared to public hospitals. Differences in nurse staffing across public hospitals were found to be associated with avoidable deaths and higher than necessary costs. More

Minimum Nurse-to-Patient Ratios Policy Saves Lives and Lowers Costs

The study, by the Center for Health Outcomes and Policy Research (CHOPR) at the University of Pennsylvania School of Nursing, and the Queensland University of Technology School of Nursing, evaluated legislation enacted in 2016 as a safety measure. The new policy limited the average number of patients per nurse to four, similar to pending legislation in New York and Illinois. “The positive results in Queensland should inform policies in the U.S. and elsewhere,” said lead-author Matthew McHugh, PhD, the Independence Chair for Nursing Education and CHOPR Director.

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

J. Margo Brooks Carthon, PhD, RN, FAAN, Associate Professor of Nursing and co-author..J. 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.”
