P2.16-33 - What Influences Patient Decision-Making About Lung-Cancer Treatment? A Discrete Choice Experiment (Now Available) (ID 485)
10:15 - 18:15 | Author(s): Richard De Abreu Lourenco
- Abstract
Background
Despite major advances in radiotherapy, surgery remains the treatment of choice for patients with stage I non-small cell lung cancer. We sought to investigate what influenced preferences for surgery or SABR among cancer patients.
Method
Using a discrete choice experiment (DCE) survey, we asked cancer patients to choose between lung cancer treatment options described by: type of treatment, chance of being cancer free for 12 months, chance of experiencing life threatening complications, chance of ongoing complications, impact on usual activities, who recommended treatment, whether treatment is usual care and out-of-pocket (OOP) costs. Each respondent completed nine choice questions. Choices were analysed using latent class analysis.
Result
A total of 204 responses were received (57% female). Of these, 20 reported a diagnosis of lung cancer; the rest had been diagnosed with other cancers, including 53 with melanoma. Overall, the chance of being without cancer was considered the most important attribute and costs the least. The latent class analysis identified three groups: Group 1 (21%) was focussed on costs and the doctor’s recommendation; Group 2 (60%) focused on the intervention (with a preference for surgery over radiotherapy), efficacy, side effects, functioning, doctor’s recommendation and the highest level of OOP costs; Group 3 members (19%) were focused on the doctor’s recommendation only. Women are more likely to be in Group 1 relative to 3, and those with higher educational attainment are more likely to be in Group 2 than 3. A more substantive analysis showed further differences between groups in terms of their tumour status, gender, educational attainment and health-care card status.
Conclusion
The results of this study show that a doctor’s recommendation is a vital factor in patients’ decision-making. The importance of this finding is emphasised by the fact that Group 2, representing 60% of respondents, preferred surgery over radiotherapy. Advocates of radiotherapy as a curative intervention for lung cancer need to educate doctors as well as patients about its potential side-effects, benefits and costs.
