PMID 33650707WHAT IT FOUND
Hospitals with better nurse work environments had lower 7- and 30-day readmissions and shorter stays for stroke patients.
Improving nursing supports, autonomy, and teamwork may help patients recover and go home sooner.
Key findings
01Better nurse work environments were associated with 4% lower odds of 7-day readmission and 3% lower odds of 30-day readmission.
02Better nurse work environments were associated with 3% lower likelihood of longer hospital stays.
03Nurse staffing levels alone showed no significant association with stroke patient outcomes.

What it does not show
The study is cross-sectional, so it shows an association but cannot prove that improving the work environment directly causes better patient outcomes. Researchers could not link specific patients to the individual nurses who cared for them, so the analysis treats the work environment as a general hospital characteristic rather than a unit-level or individual-level factor. The data lacked measures of stroke severity and specific care timing, such as how quickly anticoagulation was started, which are key drivers of outcomes. The nurse survey had a low response rate of 26%, which may introduce bias if only nurses with certain views on their work environment responded.
Declared interests
The authors declare no conflicts of interest. The study was supported by an NIH grant.
The easy way to misread this
Do not assume that simply reducing the number of patients per nurse will lower readmissions. The study found that nurse staffing levels had no significant association with outcomes; the benefit came from the broader work environment, including leadership support and autonomy.
