Racial Disparities in Stroke Readmissions Reduced in Hospitals With Better Nurse Staffing.

The study is cross-sectional and observational, so it cannot prove that better nurse staffing caused smaller disparities. It used claims data and did not measure stroke severity, quality of thrombolytic programs, care coordination, or transitional care support. It did not account for the roles of occupational therapists, physical therapists, neurologists, or intensivists. Nurse staffing was estimated from nurses' reports of their last shift and averaged to the hospital level, so it provides limited detail about actual care during the stroke admission. Race was taken from state discharge records, not self-reported, so misattribution is possible. The study included only Black and White patients aged 65 and older with ischemic stroke in four states, so it may not apply to other groups or settings.

The authors declare no conflicts of interest. The article is tagged as supported by N.I.H., Extramural.

Do not conclude that raising nurse staffing will reduce racial disparities in stroke readmissions. The study is observational and found a link, not proof of cause. It also did not measure the nursing care, discharge education, or social support that might explain the difference.
