The median number of years nurses have been working at their organizations dropped from 3.58 in 2021 to 2.78 in 2022, according to a new study by Epic Research—reflecting the continuation of significant nurse turnover.
Study details and key findings
For the study, researchers analyzed data for more than 26 million 12-hour nursing shifts from 539,765 RNs at 189 U.S. health care organizations.
To measure turnover, the researchers calculated the median length of time nurses have been at their current organizations. Overall, the researchers found that the median tenure for nurses dropped from 3.58 years in March 2021 to 2.78 years in March 2022—an almost 20% decline over the course of the past year.
Although this decrease in median nurse tenure was seen across the United States, it was most prominent in the West, which saw a 32.2% decline in median tenure between March 2021 and March 2022. In comparison, the Northeast, Midwest, and South saw a 17.7%, 16.4%, and 11.3% decline, respectively, over the same period.
In addition to median tenure, the researchers also measured nurse turnover by calculating the percentage of shifts covered by new nurses, or a nurse who started working at an organization in the last 30 days.
The shifts covered by new nurses increased in all U.S. regions, with the largest increases seen in the South and West. In the South, the percentage of shifts covered by new nurses peaked in September 2021 at just under 5%. In the West, the percentage of shifts covered by new nurses peaked in February 2022 at around 5.5%. In March 2022, 3.4% of shifts in the South were covered by new nurses, followed by 2.9% in the Midwest, 2.6% in the West, and 2.6% in the Northeast.
The researchers also analyzed the distribution of shifts based on a nurse's tenure at an organization. Nurses who had less than one year of tenure worked the largest number of 12-hour shifts, and this number increased by 55.5% between March 2021 and March 2022. This change occurred across all U.S. regions, but was most prominent in the South and West. (Davis, HealthLeaders Media, 6/6; Thayer et al., Epic Research, 6/2; Cacciaglia, Epic Share, 5/9)
