Using a Chinese time trade-off approach to explore the health utility level and quality of life of cancer patients in urban China: a multicentre cross-sectional study.

PURPOSE: A quality of life assessment is useful in identifying a specific health impact on patients who are suffering from various medical conditions. This study estimated the quality of life among patients with cancers of the lungs, breast, colorectum, oesophagus, liver, and stomach in urban China and evaluates the associated factors.

METHODS

This study employed a random cluster sampling strategy to recruit patients with lung, breast, colorectal, oesophageal, liver, or stomach cancer from eleven third-grade class-A (the highest level) hospitals in Beijing between October 2013 and May 2014. We performed a quality of life survey that included solicitation of sociodemographic and clinical information and the use of a EuroQoL five-dimension three-level questionnaire. We applied the Chinese time trade-off method to calculate the health utility values, which were transformed into binary variables (using the median as the cut-off). In addition, multivariable logistic regression analysis was used to examine the factors associated with the quality of life.

RESULTS

A total of 637 patients (91 with lung cancer, 152 with breast cancer, 60 with colorectal cancer, 108 with oesophageal cancer, 154 with liver cancer, and 72 with stomach cancer) were included in this study; the medians of the health utility values were 0.780, 0.800, 0.800, 0.860, 0.800, and 0.870, respectively. The most common concerns for patients of all six cancer types were pain/discomfort and anxiety/depression. The reported health status of patients was associated with various demographic and clinical variables.

CONCLUSION

This study highlighted that pain relief and psychological support are important aspects of patient management for those with these types of cancer. Individuals with factors associated with a poorer quality of life should be targets for additional support.
