Randomized Controlled Trial Multicenter StudyThe effect of postal questionnaire burden on response rate and answer patterns following admission to intensive care: a randomised controlled trial.
The effects of postal questionnaire burden on return rates and answers given are unclear following treatment on an intensive care unit (ICU). We aimed to establish the effects of different postal questionnaire burdens on return rates and answers given. ⋯ In survivors of intensive care, questionnaire burden had no effect on return rates. However, questionnaire burden affected answers to the same questionnaire (EQ-5D-3 L).
