A new study gives some Long Island hospitals poor marks when it comes to patient care, and some residents say they're not surprised.

A study by The Alliance for Quality Health Care and the Niagara Health Quality Coalition gives Nassau University Medical Center and Stony Brook University Medical Center below average grades. The study, based on data from two nonprofit state health groups, found Stony Brook scored poorly for safety, including infections due to medical care. NUMC also received bad marks for factors including mortality rates from acute stroke and hip fractures.

Stony Brook did score above average when it comes to treating heart attacks.

A spokesperson for Stony Brook says the hospital is trying to verify the accuracy of the data, adding the facility is taking steps to improve performance. NUMC maintains the data is from 2005 and is inaccurate today.

While some Long Islanders say they feel perfectly safe going to either facility, others say they are not shocked by the report.
