Some Long Islanders are frustrated with the quality of care at their nearest hospitals after a LeapFrog Group study rated hospitals across the country.

Celia Whitfield lives in Hempstead. Two of her closest hospitals, Mercy Hospital and Nassau University Medical Center, received "D" grades on the recent safety analysis.

She says she takes her mother all the way to Manhasset to get better care.

"I usually take her out to North Shore, which is a good 20 minutes or so drive for me from Hempstead," Whitfield says. "But I would like to see her get the best care and I feel like that's where I have to take her."

Many of the "A" and "B" rated hospitals are concentrated on the wealthier North Shore while the "C" and "D" rated hospitals are closer to areas like Hempstead and the South Shore.

Good Samaritan Hospital received a "D," in for part for having too many MRSA infections, while Nassau University Medical Center was given a "D" for higher number of deaths from treatable complications.

Mercy Hospital was given a low grade for leaving dangerous objects in patients' bodies after surgery.

Jeff Reynolds. of the Family & Children's Associations, says the study shows the inequality in the health care system that the pandemic helped to identify.

"These grades are a clarion call I think to fix the disparities coming out of COVID to make sure we do it better," Reynolds says

In response to the study, Nassau University Medical Center said the scores are misleading because they rely on data that is more than a year old. They anticipate better scores going forward.

Catholic Health Services is the group in charge of Mercy Hospital and Good Samaritan Hospital. They highlighted the "A" rating St. Francis Hospital received and said areas for focused improvement have been identified.
