Nursing Fatigue, Work Hours, and Practice Errors: A Study Review
This paper critically examines a study by Thomas (2005) that investigated the relationship between nursing work hours, fatigue, and practice errors among nurses reported to the National Council of State Boards of Nursing. Using the TERCAP methodology and questionnaire data from 122 nurses and 117 employers, the study's surface findings suggested no significant link between overtime and errors. However, qualitative responses revealed that nurses described feeling overwhelmed, rushed, and stressed — states that may constitute fatigue by another name. The paper explores the study's limitations, its implications for nursing practice, and how its findings both challenged and reinforced assumptions about workload, fatigue, and the risk of errors during 12-hour shifts.

What makes this paper effective
- The paper goes beyond surface-level findings to interrogate the methodology and self-reported nature of the data, demonstrating critical thinking about research limitations.
- It distinguishes between quantitative TERCAP data and qualitative open-ended responses, showing awareness of how different data types can tell different stories.
- The conclusion directly ties back to the opening assumptions, clearly identifying which were strengthened and which were weakened by the study's findings.
Key academic technique demonstrated
The paper models source critique effectively: it summarizes the study's findings faithfully but then identifies internal contradictions — particularly that nurses who denied fatigue nonetheless described feeling "overwhelmed and rushed," which the author argues is fatigue under a different label. This move from summary to critique to implication is a strong undergraduate analytical pattern.
Structure breakdown
The paper opens with a summary of the study's scope and participant data, moves into methodology, then presents findings with critical commentary woven in throughout. A dedicated limitations section addresses reliability concerns, followed by practice implications and a closing synthesis that maps findings back to original assumptions. The single source is handled in depth rather than breadth.
Overview of the Thomas (2005) Study
Thomas (2005) analyzes the responses of nurses who were reported to the National Council of State Boards of Nursing for nursing errors. The responses were gathered from questionnaires delivered to both the reported nurses and their employers. The focus of the questionnaires was to identify any relationship — if one existed — between the number of working hours of the reported nurses, the incidents in question, and nursing fatigue.
A total of 117 employers and 122 nurses responded. The responses indicated that almost all nurses who were reported for incidents worked 40 or fewer hours per week in total — that is, taking into account any and all jobs a nurse might hold — and that "the vast majority of nurses denied experiencing fatigue" (Thomas, 2005, p. 2). The questionnaire responses thus suggested no relation between nursing incidents or errors and nursing fatigue, mainly because nearly 70% of the nurses who responded reported working only 40 hours or fewer per week. Twenty percent reported working between 40 and 50 hours per week, 7% reported working between 50 and 60 hours per week, and 5% reported working more than 60 hours per week. That means only about one-third of respondents actually worked more than what is considered a full work week's load.
However, this is not a fair assessment of whether a nurse experiences fatigue. As Thomas points out, many nurses may have felt pressure to respond that they did not feel fatigued in the questionnaire's open-ended section, which introduces a measure of unreliability to the study overall. In short, the study is helpful in showing how many nurses reported for errors worked overtime, yet it does not definitively determine whether fatigue was or was not a variable in the errors committed.
