Prevention of Surgical Site Infections

2014-08-26 22:43:28 | BioPortfolio


The primary research question is whether interventions to prevent caregiver and system errors will increase the proportion of laparotomy patients who receive recommended measures to prevent surgical site infections.


Background: Surgical site infections (SSIs) cause significant and largely preventable morbidity, mortality, and resource use due to failure to comply with evidence-based guidelines. Quality improvement programs report increased compliance with these guidelines, but are subject to a variety of biases.

Hypothesis: The primary hypothesis is that a targeted intervention program will increase the proportion of patients in a county hospital who receive recommended interventions to prevent SSIs, when assessed in the most rigorous feasible clinical trial. The specific aims of the trial are to establish practical surveillance measures to determine the percentage of patients whose care complies with 5 major guidelines to prevent SSIs; to use chart review, direct observation, attitude surveys, and focus groups to identify, quantify, and address latent and active errors linked to non-compliance, and to develop, implement, and assess the effectiveness of an intervention program to increase guideline compliance.

Study Design: An innovative trial design will be performed with 3 staggered phases in the two major county hospitals in Houston, TX. This design allows for adjustment for temporal trends and hospital differences in assessing the intervention program in a large, high-risk, disadvantaged urban population. Based on a compliance goal of 95%, this design has adequate power to detect even a small absolute increase ( >= 5%) above baseline in the percentage of patients receiving all 5 recommended preventive measures.

Medical and Biotech [MESH] Definitions

Infection occurring at the site of a surgical incision.

Pathologic process consisting of a partial or complete disruption of the layers of a surgical wound.

Intraocular infection caused mainly by pus-producing bacteria and rarely by fungi. The infection may be caused by an injury or surgical wound (exogenous) or by endogenous septic emboli in such diseases as bacterial endocarditis or meningococcemia.

The application of a vacuum across the surface of a wound through a foam dressing cut to fit the wound. This removes wound exudates, reduces build-up of inflammatory mediators, and increases the flow of nutrients to the wound thus promoting healing.

Removal of degenerated and necrotic epithelium and underlying connective tissue of a periodontal pocket in an effort to convert a chronic ulcerated wound to an acute surgical wound, thereby insuring wound healing and attachment or epithelial adhesion, and shrinkage of the marginal gingiva. The term is sometimes used in connection with smoothing of a root surface or ROOT PLANING. (Jablonski; Illustrated Dictionary of Dentistry, 1982)
