Changes in State Specific SIRs for Colon Surgery Infections 2012-2013

$79 / year

The Standardized Infection Ratio (SIR) is a statistic used to track healthcare associated infections (HAIs) over time, at a national, state, or facility level. The SIR compares the actual number of HAIs at each hospital, to the predicted number of infections. The predicted number is an estimate based on national baseline data, and it is risk adjusted. Risk adjustment takes into account that some hospitals treat sicker patients than others.

Complexity

A surgical site infection like colon surgery is an infection that occurs after surgery in the part of the body where the surgery took place. Surgical site infections can sometimes be superficial infections involving the skin only. Other surgical site infections are more serious and can involve tissues under the skin, organs, or implanted material. Centers For Disease Control and Prevention (CDC) provides guidelines and tools to the healthcare community to help end surgical site infections and resources to help the public understand these infections and take measures to safeguard their own health when possible.

The Standardized Infection Ratio (SIR) is a statistic used to track healthcare-associated infections (HAIs) over time, at a national, state, or facility level. lower SIRs are better.
If the SIR is 1, then the number of actual infections is the same as the number of predicted infections.
If the SIR is less than 1, then the number of actual infections is less than the number of predicted infections.
If the SIR is greater than 1, then the number of actual infections is greater than the number of predicted infections.
Usually, a low SIR reflects the results of robust HAI prevention strategies. These scenarios are exciting, and CDC is working with facilities and states to learn and share best practices.
