Four Long Island hospitals rated poorly when it comes to critical patient safety measures, according to a new federal report.

The government ranked facilities on a scale of 1-10 with 10 being the worst. Stony Brook University Hospital, North Shore University Hospital in Manhasset, Southside Hospital in Bay Shore and Plainview Hospital all scored within the 8 range for hospital-acquired conditions, such as infections and patient injuries.

As a penalty, Manhasset will lose $3 million in Medicare payments for a year.

North Shore LIJ, which includes Manhasset, Southside and Plainview hospitals, issued a statement that said in part, "Whenever the state or federal governments or hospital report cards identify a quality issue, we are already aware of it and working aggressively to resolve it."

Stony Brook, which says it will lose more than $1.5 million, says it's already made changes.

"Still we know that there is always room for improvement, that no complication is acceptable, and we actively support and implement industry initiatives to enhance safety and quality," said a Stony Brook spokesperson.

The state health department maintains a website that profiles all hospitals, home health agencies, nursing homes and physicians in the state. Visitors to the site can check quality scores for different departments, complaints, inspections and any citation or enforcement actions.
