Study finds that blacks are readmitted more often than white peers.

Older black adults were more likely to be readmitted to a hospital after an elective hip or knee replacement and are more adversely affected by insufficient hospital nurse staffing, a new study has found.

Older black adults have a 30% increased likelihood of readmission compared with their white counterparts, according to the University of Pennsylvania School of Nursing.

Investigators found that each additional patient in a nurse’s workload was associated with an 8% readmission odds increase among whites but a 15% increase in odds among older black patients.
