Key result
Higher nurse staffing after cardiac surgery links to fewer unplanned ICU readmissions and lower mortality.
Why the study?
The impact of nurse staffing levels on unplanned readmissions and postoperative in-hospital mortality in cardiac surgery patients was not well established.
Do higher nurse staffing levels reduce unplanned readmissions and in-hospital mortality in postoperative cardiac surgery patients?
Do higher nurse staffing levels reduce unplanned readmissions and in-hospital mortality in postoperative cardiac surgery patients?
Higher nurse staffing levels in postoperative cardiac surgery care are associated with reduced in-hospital mortality and unplanned readmissions.
May support higher staffing in cardiac surgery units; leaves open confirmation of broader effects in larger international studies.
Implications for practice and research: Higher nurse staffing levels for postoperative care of cardiac surgery patients reduces the risk of unplanned re-admission to the intensive care or operating theatre and in-hospital mortality. Larger international studies are needed to assess the effect of nurse staffing levels and risk of hospital-wide adverse events.

Frost et al. (2012) studied this question. Higher nurse staffing levels for postoperative cardiac surgery patients reduce the risk of unplanned readmission to the ICU or operating theatre and in-hospital mortality.
