The study also ranked managers by changes in productivity that occurred when they were added or removed from a team, as well as changes in productivity of workers who moved from one boss to another.
Replacing a low-performing boss with a high-performing boss raised productivity by 12%. Also, assigning a tenth worker to the team raised productivity about 11%. This finding is consistent with other nursing-related research which finds a higher nurse-patient ratio is associated with better outcomes.
For example, a study published over the summer in the American Journal of Infection Control found that hospitals with more nurses and lower patient-nurse ratios had fewer infections than hospitals with fewer nurses.
The effect of good nurse leaders can't be overstated, and this new study about high-quality bosses is only one piece of evidence to support that fact. It's something that it's my job to think about.
