Abstract

Background: Access to cardiac treatments has been documented to vary with patients' age. It is unknown whether these variations reflect patients' treatment preferences. We aimed to investigate patients' preferences for cardiology treatments and develop a Patients' Preferences Questionnaire.

Methods: Semi-structured interviews with primary care patients with diagnosed angina with postal follow-up. The resulting Patients' Preferences Questionnaire was tested with newly admitted inpatients with acute coronary syndrome and with patients in primary care.

Results: The Patients' Preferences Questionnaire was psychometrically sound. Analyses of preference subscale scores showed that the most positive preference scores were for medication. Angioplasty scored highest at the negative end of the scale. Detailed analyses showed that older people and women were less likely to prefer coronary artery bypass surgery (CABG), reflecting its greater level of invasiveness. Older people (aged over 75 years, compared to people aged under 75 years), but not women, were also more cautious in their strength of preference for angioplasty. More positive attitudes towards CABG surgery, and more negative attitudes towards medication, were associated with greater impact of the condition on life.

Conclusions: The research resulted in a psychometrically sound Patients' Preferences Questionnaire. There was some evidence to support the view that older people's weaker preferences for CABG may contribute slightly to variations in the provision of re-vascularization. There was also variation in preferences within age groups, cautioning against the assumption that all or most older people are more reluctant than younger people to undergo invasive procedures.
