Concord, NH – The New Hampshire Department of Health and Human Services (DHHS), Division of Public Health Services (DPHS) today released the 2012 Healthcare-Associated Infections (HAIs) Hospital Report and the 2012 Healthcare-Associated Infections (HAIs) Ambulatory Surgery Center (ASC) Report based on data from the 31 hospitals and 27 ASCs in the State. The reports, mandated by law, look at the rates of specific HAIs. For hospitals, central line–associated bloodstream infections, catheter-associated urinary tract infections, and surgical site infections following heart, colon, abdominal hysterectomy, and knee surgeries are reported. For ASCs, surgical site infections following breast, hernia, and open reduction of fracture procedures are reported.

The reports also provide data on hospitals’ and ASCs’ compliance with measures that are put in place to protect patients from acquiring infections. These data include infection prevention practices during central line insertions in hospitals, the appropriate use of antimicrobials during surgical procedures in hospitals and ASCs, and influenza vaccination rates among hospital and ASC staff.

"The numbers for hospitals are showing improvement over last year so we are encouraged by that and hope to see continued improvement in the future,” said Dr. José Montero, Director of Public Health at DHHS. “It is also good to get data from Ambulatory Surgical Centers for the first time. The intent of this data tracking is to find out how we are doing as a State and to make improvements to better protect the health of New Hampshire’s citizens and we are pleased that that is happening."


Overall, statewide infection rates in hospitals are showing improvement compared with national data. A total of 198 HAIs were reported by hospitals in 2012, compared with 110 in 2011, 114 in 2010, and 134 in 2009. There were more infections reported in 2012 as hospital reporting requirements were expanded in 2012. The overall observed number of HAIs in New Hampshire hospitals was 25% lower than expected based on national data; there were 54% fewer central line-associated bloodstream infections and 29% fewer surgical site infections. There were 11% more catheter-associated urinary tract infections but this difference is not statistically significant and the number of infections observed is considered similar to national data.

Statewide hospital adherence to four infection-prevention practices during central line insertions was 96.2% (similar to 2011). Antimicrobial prophylaxis was given accurately more often than the national average (over 97%). The overall staff influenza vaccination rate in hospitals was 91.2%, which has been significantly improving since 2008 and exceeds the Healthy People 2020 goal of 90%.

Ambulatory Surgery Centers:

Overall, statewide infection rates in ASCs are similar compared with national data. A total of four surgical site infections were reported by ASCs for 2012 and the overall observed number of surgical site infections in NH ASCs was 43% fewer than expected based on national data. This difference is not significant and considered similar to national data. Statewide ASC adherence to intravenous antibiotic prophylactic timing guidelines to prevent surgical site infection was 98.4%. The overall staff influenza vaccination rate in ASCs was 83.5%.

The collection of the data is meant to be a tool for hospitals and ambulatory surgery centers to track their progress and identify areas that require special attention, for DHHS to see where improvements can be made, and to help inform consumers. To view the report, visit
