In a 2003 study, later confirmed in 2011, Dr. Aiken found that a 10% increase in the number of BSN-prepared nurses at a hospital reduced the likelihood of patient deaths by 5%. In direct comparison between hospitals that hired BSN-prepared nurses with those that didn’t between 1999 and 2006, Dr. Aiken found more evidence that hospitals with BSN-prepared nurses had greater declines in mortality rates.
Additionally, her research demonstrated a 7% increase in 30-day mortality after common surgical procedures with each additional patient added to a nurse’s workload. Dr. Aiken’s team also discovered that with in-hospital cardiac arrest patients, every patient added to a nurse’s workload is associated with a 5% decrease in the likelihood of surviving discharge.
Experts today are recognizing the importance of hiring nurses who are prepared with a BSN. Based on Dr. Aiken’s research, more education is associated with more knowledge and ability to navigate the consistently changing and complex healthcare system. In fact, the National Academy of Medicine’s 2010 report recommends that 80% of U.S. nurses have a bachelor’s degree by the year 2020. This report was influenced by Dr. Aiken’s research.
