Review12 h shifts and rates of error among nurses: A systematic review
Section snippets
Introduction/background
Work schedules should be optimised for both employees and patients. The introduction of 12-h shifts into rostering/scheduling systems has been one approach implemented in workplaces with the intention of improving the flexibility of work hours for nurses. The approach has proven popular, with many proponents citing good quality time off work, ease of travel to work, improved relationships with patients, and better family time as benefits (Estryn-Béhar et al., 2012, O’Connor, 2011, Richardson et
Literature review
Previous reviews have explored links between shift length and patient outcomes with results described as inconclusive (Bae and Fabry, 2014, Estabrooks et al., 2009). Bae and Fabry examined the relationship between nurse work hours/overtime and nurse and patient outcomes. They determined there is strong evidence supporting a positive relationship between working long hours and adverse nurse outcomes; however, their findings regarding shift length were not definitive – while they note that
Aim
The aim of this systematic review was to determine the effect of working 12 h or more on a single shift in an acute care hospital setting compared with working less than 12 h on rates of error among nurses. The question posed was: what is the effect of working 12 h or more on a single shift in an acute care hospital setting compared with working less than 12 h on rates of error among nurses?
Method
The review is based on the Joanna Briggs Institute systematic review process. This approach covers search strategy, inclusion/exclusion criteria, methodological quality, results and data synthesis.
Description of studies
Of the 13 studies included, two were from Japan (Arimura et al., 2010, Tanaka et al., 2010), one was from Australia (Dorrian et al., 2006), one was from Canada (Wilkins and Shields, 2008), one was from Europe (Griffiths et al., 2014), and eight were from the United States of America (Mills et al., 1983, Ritter, 1981, Rogers et al., 2004, Scott et al., 2006, Stone et al., 2006, Trinkoff et al., 2007, Witkoski Stimpfel et al., 2012, Witkoski Stimpfel et al., 2013). For the purposes of critical
Discussion
This systematic review has examined the relationship between shift length and error amongst nurses working in acute care settings. While earlier studies have examined the relationship between nurse work hours/overtime and nurse and patient outcomes (Bae and Fabry, 2014) and between shift length on quality of patient care (Estabrooks et al., 2009), a specific review of studies examining 12 h shifts, error and nurses has not previously been done. Our findings regarding shift length and error
Conclusion
In conclusion, this review shows that rates of error appear higher among nurses working 12 h or more on a single shift in an acute care hospital. Although this review did not explore other potential variables that may mediate or moderate this pathway such as fatigue, stress, skill mix or scheduling practices, it is clear that a relationship does exist. As such, we recommend workplaces review current scheduling practices with a view to limiting shift length to 8–10 h where possible. We also

2020, International Journal of Nursing StudiesCitation Excerpt :This is also in line with results from a Danish self-rostering study (Garde et al., 2012). Among nurses, working long shifts has been associated with negative outcomes, such as fatigue (Dall'Ora et al. 2016) and higher error rates (Clendon and Gibbons 2015). However, in this study, the proportion of long work shifts of all shifts was low (< 10% of all shifts in the participatory scheduling) and the results showed no other differences in excessive sleepiness except for evening shifts according to whether the scheduling was participatory or traditional.

2019, Applied Nursing ResearchCitation Excerpt :The second review stated that nurse fatigue was associated with multiple factors comprising of work-related, personal, and organizational matters (Smith-Miller, Shaw-Kokot, Curro, et al., 2014). The third review concluded that 12-h shift nurses were at higher risk of making errors (Clendon & Gibbons, 2015). The discussion above shows that literature on nurses working 12-h shifts has focused on studying the factors associated with fatigue, such as sleep debt, shift schedules, heavy workload, and lack of social support.
