Infection prevention and control in computed tomography: creating a national survey

Infection prevention and control (IPC) is essential for quality healthcare, with healthcare associated infections (HAI) a known risk to patients requiring medical imaging (MI). To date, few papers have adopted a national approach to understanding or benchmarking the knowledge of, attitudes toward, and practice (KAP) of IPC in the context of MI and no validated surveys or scales are identified in the literature. The Computed Tomography (CT) suite is a unique MI environment where radiographers deliver prescription medicines to patients via intravenous (IV) means through an injector system. This paper describes the development of a survey that informs the use of IPC processes in the CT suite.

Standard Precautions via current national guidelines formed the benchmark of the survey, with a KAP survey used as the framework to explore IPC. The questions and associated responses are developed based on the National Health and Medical Research Council (NHMRC) guidelines, industry/professional protocols and adapted to the equipment and practices commonly used in the CT suite of MI departments by radiographers and nurses.

Key survey development steps are described to include the justification of the benchmarking source, the survey framework and design. Detailed information is given to show the evolution of truth statements and sources, KAP question variations, and rationales for the methodology of question responses. National guidelines are mapped to survey questions and responses and pilot testing reflections are included.

This paper reports on the construction of a standardised KAP survey for IPC specific to the CT suite in the Australian healthcare setting. The survey is ready for dissemination amongst MI departments. Documented use will aid validation and reliability as a survey tool to measure and map IPC specifically in relation to IV contrast administration.
