The state released its first report yesterday on hospital infections, showing that patients developed 134 infections last year while being treated for another condition -- a number lower than expected, based on national data. The report, the result of a 2006 state law, examined infections during 2009 that developed from central lines -- catheters inserted in blood vessels near the heart or other major vessel -- and their insertion practices. The report also looked at infections that developed after heart, colon and knee surgeries, and at influenza vaccination rates among hospital staff. Officials said the number infected overall was 26% lower than expected, based on national data from 2006 to 2008. The report said officials expected to see 180 infections at New Hampshire hospitals in that time period.
