Audit in infection control--data analysis and infections in the intensive care unit
1Public Health Laboratory, Derriford Hospital, Plymouth, Devon, UK.
Abstract:
The importance of high standards of infection control practices in intensive care units is widely accepted. Despite this, few objective measures of the efficacy of such practices have been developed. This hampers clinical audit, which is essential if nosocomial infections are to be kept to a minimum. Small sample size, multiple dependent variables, difficulty in matching populations, and the covert effects of confounding factors and bias, all add to the problems of designing meaningful audit programmes in intensive care settings. Nevertheless, useful analysis can be attempted now that appropriate standards and scoring systems are available. Computer systems can simplify data collection, analysis and reporting but they are no substitute for careful preparation and good statistical technique.
Insights
Implementing effective infection control in intensive care units (ICUs) is crucial. Objective measures are needed to audit these practices and minimize hospital-acquired infections, despite challenges in data collection and analysis.
Area of Science:
- Healthcare Management
- Infection Prevention and Control
- Critical Care Medicine
Background:
- High standards of infection control are vital in intensive care units (ICUs).
- Objective measures to assess the efficacy of infection control practices are currently lacking.
- This deficiency hinders effective clinical audit and the minimization of nosocomial infections.
Purpose of the Study:
- To highlight the challenges in designing audit programs for intensive care settings.
- To emphasize the need for objective measures to evaluate infection control practices.
- To discuss the potential of available standards, scoring systems, and computer technology in facilitating meaningful analysis.
Main Methods:
- Acknowledging the difficulties in audit program design, including small sample sizes, multiple variables, population matching issues, and confounding factors.
- Discussing the utility of established standards and scoring systems for analysis.
- Recognizing the role of computer systems in data management and reporting.
Main Results:
- Despite inherent complexities, useful analysis of infection control practices is achievable.
- Appropriate standards and scoring systems are now available to support such analysis.
- Computer systems can aid data collection and reporting but require careful preparation and statistical expertise.
Conclusions:
- Objective measurement and auditing of infection control practices in ICUs are essential for reducing nosocomial infections.
- While challenges exist, current tools and methodologies enable more effective evaluation.
- Successful implementation requires rigorous planning and sound statistical approaches, complemented by technology.
