Summary
A recent study indicates that stroke survival is associated with the number of nurses available at weekends, but not the frequency of doctors’ ward rounds. The importance of the so-called “weekend effect” is widely recognised across many areas of medicine, particularly with regard the importance of 24/7 consultant input in reducing weekend mortality rates; in contrast this study points to the relatively higher importance of nurse staffing levels for stroke care.
The researchers speculate that one of the main the reasons behind the particular importance of the nurse to patients ratio for mortality in stroke units at weekends may be the significant impact of better attention to patient hydration and nutrition upon post-stroke survival.
