Aim. To examine the relationship between nurse stafﬁng and nurse-rated quality of nursing care and job outcomes.
Background. Nurse stafﬁng has been reported to inﬂuence patient and nurse outcomes.
Design. A cross-sectional study with a survey conducted August–October 2007.
Methods. The survey included 1365 nurses from 65 intensive care units in 22 hospitals in Korea. Stafﬁng was measured using two indicators: the number of patients per nurse measured at the unit level and perception of stafﬁng adequacy at the nurse level. Quality of care and job dissatisfaction were measured with a four-point scale and burnout measured by the Maslach
Burnout Inventory. Multilevel logistic regression models were used to determine the relationships between stafﬁng and quality of care and job outcomes.
Results. The average patient-to-nurse ratio was 2Æ8 patients per nurse. A ﬁfth of nurses perceived that there were enough nurses to provide quality care, one third were dissatisﬁed, half were highly burnt out and a quarter planned to leave in the next year.
Nurses were more likely to rate quality of care as high when they cared for two or fewer patients (odds ratio, 3Æ26; 95% conﬁdence interval, 1Æ14–9Æ31) or 2Æ0–2Æ5 patients (odds ratio, 2Æ44; 95% conﬁdence interval, 1Æ32–4Æ52), compared with having more than three patients. Perceived adequate stafﬁng was related to a threefold increase (odds ratio, 2Æ97; 95% conﬁdence interval, 2Æ22–3Æ97) in the odds of nurses’ rating high quality and decreases in the odds of dissatisfaction (odds ratio,
0Æ30; 95% conﬁdence interval, 0Æ23–0Æ40), burnout (odds ratio, 0Æ50; 95% conﬁdence interval, 0Æ34–0Æ73) and plan to leave
(odds ratio, 0Æ40; 95% conﬁdence interval, 0Æ28–0Æ56).
Conclusions. Nurse stafﬁng was associated with quality of care and job outcomes in the context of Korean intensive care units.
Relevance to clinical practice. Adequate stafﬁng must be assured to achieve better quality of care and job outcomes.
Key words: burnout, intensive care unit, intention to leave, job dissatisfaction, nurse stafﬁng, quality

Providing adequate nurse stafﬁng has been discussed as a key working condition of hospital nurses. However, nurses in many countries have continuously reported that hospitals are

not staffed with enough nurses. Aiken et al. (2001a) pointed out that the proportion of nurses reporting that there were enough registered nurses on staff to provide quality patient care decreased from 98% in 1986 to 51% in 1998. In an international comparison of ﬁve developed countries, only
