CHOPR Research Wins Prestigious Awards and Endorsements

Investigators saw a surge of interest as projects into health outcomes and quality of care came to the forefront due to increased scrutiny on the impact of working conditions for nurses.

Paper on the effects of staffing size on nurse and patient outcomes is the 2003 AcademyHealth Article of the Year

CHOPR Investigators, Linda H. Aiken, Sean P. Clarke, Douglas Sloane, Julie Sochalski, and Jeffrey Silber, published the groundbreaking research in The Journal of the American Medical Association (JAMA). Ten thousand nurses in 168 Pennsylvania hospitals were surveyed for the study. Researchers looked for the effects of staffing size on nurse and patient outcomes and identified a link between patient load and mortality. The landmark paper went on to win several awards including the American Academy of Nursing Media Award and the 2003 AcademyHealth Article of the Year Award. In an accompanying JAMA Editorial, “Meeting the Challenge of Nursing and the Nation’s Health”, co-authors, Dr. Edward O’Neil and Dr. Jean Ann Seago said, 

“Aiken et al. have provided an important piece of scholarship that helps us to understand more completely the contributions of more intensive nurse staffing to patient safety, outcomes, and the job satisfaction of nurses.”

Key healthcare orgs. endorse the Practice Environment Scale of the Nurse Working Index as the standard measure of quality of care

The paper, by CHOPR Associate Director, Dr. Eileen Lake, titled Development of the Practice Environment Scale (PES) of the Nursing Work Index (NWI), introduced a new instrument from two prior instruments: the Nursing Work Index (NWI) by Kramer and Hafner (1989); and, the Revised Nursing Work Index (NWI-R) by Aiken and Patrician (2000). The National Quality Forum (NQF, 2004) selected the revised PES-NWI as a national voluntary standard of nursing performance in 2003. It is one of only twelve nursing standards with NQF endorsement out of over 750 currently-endorsed measures. Today, over 150 studies have utilized PES data to demonstrate that the nurse work environment is a key foundation for health care quality.

“The ultimate goal was to create and sustain practice environments that facilitate professional nursing practice, enhance the quality of patient care, and improve outcomes for both nurses and patients.” Eileen T. Lake, PhD, RN
