The use of DALYs and QALYs is not specifically utilitarian. They can be used in other frameworks. The difference is how they are weighted. For example, a utilitarian may only care about the net gain across the whole population, whereas someone motivated by (say) a Rawlsian perspective would place more moral weight on achieving gains to the worst off.
