Insomnia and fatigue were measured with validated instruments, and participants reported recent overtime work and medication errors over the previous three months across twelve error types. Negative binomial regression examined associations, adjusting for demographic and work\u2010related characteristics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Clinically significant insomnia was present in one\u2010quarter of nurses, fatigue in two\u2010thirds, and recent overtime in four in five. In adjusted analysis, insomnia and fatigue were significantly associated with higher summed self\u2010reported medication\u2010error\u2010type frequency scores, whereas overtime work was not. Estimates remained directionally consistent across sensitivity analyses, although the insomnia association was not significant when the outcome was dichotomized.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Clinically significant insomnia and fatigue were associated with a higher summed self\u2010reported medication\u2010error\u2010type frequency score, whereas an association with overtime work was not supported.
