Objective:
To explore adult medical oncology outpatients' understanding of and preferences for the format of health risk information.
Methods:
Two surveys, one assessing sociodemographic characteristics and a second survey examining perceptions of risk information.
Results:
Of the 361 (74%) consenting patients, 210 completed at least one question on risk communication. 17% to 65% of patients understood numeric risk information, depending on the format of the information. More than 50% of people interpreted a "very good" chance of remission as greater than 80%, greater than 90% or 100%. The most preferred format of information was in both words and numbers (38% to 43%) followed by words alone (28% to 30%).
Conclusion:
Numeric risk information is understood by 17% to 65% of respondents, depending on the format. Interpretation of verbal risk information is highly variable, posing a risk of misunderstanding. Provision of information in both words and numbers may assist in aiding comprehension.
