Operative related infection rates for ventriculoperitoneal shunt procedures in a children's hospital
Insights
Cerebrospinal fluid (CSF) shunt infection rates averaged 13.3% between 1982-1984. Strict definitions are crucial for accurate infection rate comparisons in CSF shunt procedures.
Area of Science:
- Neurosurgery
- Infectious Disease Epidemiology
Background:
- Cerebrospinal fluid (CSF) shunts are critical for managing hydrocephalus.
- Accurate infection rates are essential for evaluating surgical outcomes and patient safety.
Purpose of the Study:
- To determine operative-related CSF shunt infection rates at our institution from 1982 to 1984.
- To highlight the impact of numerator and denominator definitions on reported infection rates.
Main Methods:
- Retrospective analysis of CSF shunt procedures over a 3-year period.
- Strictly defined numerator (infection) and denominator (at-risk patients) data were utilized.
- A minimum 12-month post-operative follow-up was enforced.
Main Results:
- The overall average operative-related CSF shunt infection rate was 13.3%.
- Annual infection rates remained consistent (13.8%, 13.2%, 12.9%), but quarterly and surgeon-specific rates showed significant variability (5.7%–23.3%).
- Traditional calculation methods yielded considerably lower rates (6.5%–9.2%).
Conclusions:
- Operative-related CSF shunt infection rates vary significantly based on calculation methodology.
- Strictly defined numerator and denominator values are imperative for valid comparisons of published CSF shunt infection rates.
- Standardized reporting is necessary to accurately assess surgical site infections in CSF shunt procedures.
Abstract:
We determined the operative related cerebrospinal fluid (CSF) shunt infection rates for our institution over a 3-year period (1982 to 1984) using strictly defined numerator and denominator data. The minimum post-operative follow-up period was 12 months. The average surgical infection risk for a CSF shunt procedure at our institution during the study period was 13.3%. Annual infection rates were relatively constant (13.8%, 13.2% and 12.9%), however both quarterly (5.7% to 23.3%) and surgeon-specific (5.7% to 22.8%) rates varied widely. Infection rates calculated by using "traditional" numerator and denominator data were considerably lower (6.5% to 9.2%). Operative related CSF shunt infection rates should be determined by utilizing strictly defined numerator and denominator values in order to allow valid comparisons of published rates.
