The information needs of people attending for computed tomography (CT): what are they and how can they be met?

To establish patients' knowledge of CT, their views of information provided and explore the role of information in imaging.

A sample of 150 first-time outpatients attending for CT scanning at a Scottish hospital. The study had three phases: a questionnaire survey; structured interviews pre-scan and face-to-face interviews post-scan.

One hundred and twelve questionnaires were returned with 82 deemed usable. Sixty and 53 respondents participated in the pre-scan and post-scan interviews, respectively. Thirty percent of questionnaire respondents and 57.4% of pre-scan interviewees identified accurately the type of scan to be received. Scores on the knowledge test improved by the time of the pre-scan interview. During all stages of the study family members were described as a source of information. Patients reported clinicians as providing few details about the scan, and there was confusion about how results were communicated. Most interviewees thought the leaflet had prepared them for the procedure.

The study revealed a lack of familiarity with CT scanning, diverse informational needs, and the importance of personal contact in information giving.

The study raised wide-ranging issues and highlights the key role of information in the provision of diagnostic health services.
