Other Healthcare Associated Infections Measures



Surgical Site Infections from Abdominal Hysterectomy

What are we measuring and why?

Healthcare associated infections (HAI) are infections that patients acquire while receiving medical treatment in a healthcare facility. These infections are often harmful and costly to treat, but can usually be prevented through the use of proper precautions and infection control practices. The Centers for Medicare and Medicaid Services (CMS) publishes hospital HAI results, which are increasingly used to assess the quality and safety of patient care. Data are reported as a standardized infection ratio (SIR), which compares a hospital’s observed number of infections to its predicted number of infections, after adjusting for institutional characteristics known to cause differences in incidence. A lower SIR is better, with the ultimate goal of zero infections.

How are we doing and how do we compare to best practice?

Surgical Site Infections (SSI) occur in the wound created by an invasive surgical procedure, giving rise to local signs and symptoms. These infections can affect the skin around the incision, as well as the tissues, muscles, and organs beneath its surface. SSIs can be largely prevented by following recommended sterilization and infection control procedures. 

SSI rates are publicly reported for select procedures and include adult patients (aged 18+) with deep incisional and/or organ space infections occurring within 30 days of surgery. For abdominal hysterectomy, MGH’s SIR (2.30) was statistically worse than the national benchmark (1.0) in 2017. Events are rare, which causes performance to fluctuate over time. Early data for 2018 show that the number of infections is declining.

What are we doing to improve?

To reduce SSIs after abdominal hysterectomy surgery, MGH has multidisciplinary projects underway that focus on enrolling eligible women in Enhanced Recovery after Surgery pathways and on assuring optimal timing and selection of prophylactic antibiotics for women undergoing this procedure.
