New Jersey once more has two hospitals on U.S. News and World Report's newest list of best children's hospitals nationwide.

Hackensack University Medical Center's children's facility is now on the magazine's 2017 list, joining Robert Wood Johnson University's children's hospital in New Brunswick.

Bristol-Myers Squibb Children's Hospital of RWJ Hospital is ranked 39th nationally in the field of pediatric urology. Joseph Sanzari Children's Hospital, part of Hackensack, is ranked 45th in the field of pediatric neurology and neurosurgery.

Of the nation's top 10 chiildren's hospitals ranked by the magazine, the nearest one to New Jersey families is Children's Hospital of Philadelphia, or CHOP. That hospital also has a partnership with New Jersey's largest chain of hospitals, RWJBarnabas Health.

While six New York City hospitals get high marks in various specialties, none made the Top 10 list. Heading the overall list again this year is Boston Children's Hospital.

At Hackensack, Dr. Ariel Sherbany, section chief of pediatric neurology, said a key strength of the hospital is its sub-specialitists: doctors who focus on pediatric oncology, pediatric movement disorders, and neurological disorders that include pediatric epilepsy.

Its Institute for Child Development also provides diagnostic and research services related to autism.

Hackensack's children's hospital had been in the Top 50 list for several years, but had been edged out by other hospitals for the past two years. Tuesday's announcement means it has resumed its place on the list.

"I just found out this happened, and I'm very excited about it," Sherbany said.

The magazine's 11th annual rankings list the top 50 hospitals for children in each of 10 specialties. The rankings will be published in the magazine's "Best Hospitals 2018" guidebook, scheduled to be published in September.

A total of 89 hospitals placed on at least one of those specialty lists this year. That's up from last year, when 80 hospitals were recognized for their expertise in at least one specialty.

In compiling their rankings, the editors factor in a combination of clinical data and an annual survey of specialists in the field of pediatrics. The rankings also take into account mortality and infection rates, efficiency and coordination of care, along with adherence to "best practices."
