Pennsylvania, New Jersey hospitals’ mistakes are going unreported

For several years now, Pennsylvania and New Jersey hospitals have been required to report medical mistakes and serious complications to state agencies charged with reducing medical errors. But some hospitals aren't fully complying, experts say. In New Jersey, five of the state's 80 hospitals failed to report a single preventable mistake in 2007, officials said. In Pennsylvania, some facilities didn't report any serious events or even near misses that might have harmed patients.
