Abstract

Objective

This study aimed to determine stakeholders’ decision criteria preferences for formulary decisions of cancer drugs in the Ministry of Health. The secondary objective was to identify the outcome measures of interest for assessment of clinical benefits for cancer drugs.

Methods

A survey questionnaire was administered online and as hard copy using purposive sampling to 32 healthcare facilities providing cancer services and the Formulary Management Branch in the Ministry of Health. Respondents reported whether a criterion “will be considered” and weighted its relative importance on a 5-point scale. The choice of safety and efficacy/effectiveness outcomes were ranked from 1 to 5, and the minimum value of benefit for the efficacy/effectiveness outcome ranked 1 was provided. Trade-offs between survival and quality of life were also explored. Inferential statistics were used to explore difference in responses.

Results

A total of 316 healthcare professionals responded to the survey. The most important criteria for value assessment of cancer drug were safety and effectiveness. Other criteria deemed important were quality of evidence, disease severity, and patient-reported outcomes. There was no difference in the criteria preference and weights across the various respondent groups. Overall survival was the most preferred clinical benefit outcome. Overall, willingness to pay was higher for life-prolonging treatment than treatment that improved quality of life.

Conclusions

This study revealed that a wide range of criteria beyond the traditional decision-making criteria of efficacy, safety, and cost-effectiveness are important for value assessment of cancer drugs for the purpose of formulary decisions.
