Abstract / Description of output

Doctors' knowledge provides the basis to support good practice in infection prevention and control. However, there exists a paucity of validated knowledge assessment tools that can be reliably employed to identify poor knowledge levels of Clostridium difficile infection (CDI) within populations of doctors, preventing the effective identification of knowledge deficiencies and focused targeting of educational interventions. Here, we describe a development process to validate a novel CDI knowledge assessment tool for doctors. Two previously published CD! knowledge questionnaires were amalgamated to produce a combined questionnaire. Content was further evaluated by a panel of CDI experts, producing the 'Lothian' questionnaire. These questionnaires were tested in control populations comprising either infection control nurse (ICN) specialists or non-clinically trained individuals, and a cohort of medical staff. We compared the efficacy of the 'Lothian' questionnaire against that of previous questionnaire reports. We found that all of the questionnaires studied significantly discriminated between non-clinical and clinical populations (ICNs and medical staff) (P <0.001) and had similar levels of sensitivity and specificity in discrimination between these targeted populations. This study describes the development of a robust CD! knowledge assessment tool that can be used to evaluate knowledge levels among doctors, compare populations and assist the targeting of educational interventions and plot trends following such interventions.
