Surgical wound infections documented after hospital discharge
Abstract:
Shorter lengths of hospitalization may result in more surgical wound infections being documented after hospital discharge. The current investigation analyzed 1644 surgical procedures performed over a 3-month period, and documented surgical wound infections both before and for 1 month after hospital discharge. Physician and patient questionnaires were used. One hundred eight infections were noted, of which 50 (46%) were seen after hospital discharge by either the patient or the surgeon. Rates of infection were 5.2%, 7.5%, and 7.5% for clean, clean-contaminated, and contaminated-dirty categories, respectively. Had postdischarge surveillance not been used, rates would have appeared to be 2.5%, 6.5%, and 6.8% for the same surgical classes. Infections following clean and clean-contaminated procedures were more likely to be noticed after hospital discharge. Excluding those that were patient-documented, wound infection rates would have been 4.2% (clean), 6.3% (clean-contaminated) and 6.8% (contaminated-dirty). Postdischarge surveillance is imperative to meaningfully document true rates of surgical wound infection, inasmuch as increasing numbers are likely to occur only after patients leave the hospital.
Insights
Post-discharge surveillance is crucial for accurately tracking surgical wound infections. Many infections are identified after patients leave the hospital, impacting true infection rate calculations.
Area of Science:
- Surgical Infection Surveillance
- Healthcare Quality Improvement
Background:
- Shorter hospital stays may increase the incidence of surgical wound infections detected post-discharge.
- Accurate documentation of surgical site infections (SSIs) is essential for patient safety and healthcare quality.
Purpose of the Study:
- To evaluate the impact of post-discharge surveillance on the documented rates of surgical wound infections.
- To determine the proportion of surgical wound infections identified after hospital discharge.
Main Methods:
- Analysis of 1644 surgical procedures over a 3-month period.
- Collection of surgical wound infection data before and for one month after hospital discharge.
- Utilized physician and patient questionnaires for data collection.
Main Results:
- 108 infections were identified, with 46% detected after discharge.
- Actual infection rates were 5.2% (clean), 7.5% (clean-contaminated), and 7.5% (contaminated-dirty).
- Without post-discharge surveillance, rates would have been underestimated (2.5%, 6.5%, 6.8% respectively).
Conclusions:
- Post-discharge surveillance is imperative for accurate surgical wound infection rate documentation.
- A significant number of surgical wound infections occur after patients are discharged.
- Underestimation of infection rates occurs when post-discharge surveillance is not implemented.
