Understanding nurse performance in a longitudinal study
|Day:||Wed 3 Jul|
Increasingly biological data collection is included in large longitudinal studies. Typically, this is done using nurse visits at the respondent’s home. In this paper we investigate to what degree there is variation in the performance of nurses in the nurse visit, consent to blood and blood collection. Additionally, we investigate to what the degree this performance is consistent in time and in the activity and if it predicts performance in future waves. Using waves 2, 4, 6 and 8 of the English Longitudinal Study of Ageing we use multilevel models to create performance indicators. We further investigate how stable these are in time and if they can predict performance in wave 8. We conclude with a discussion about how this information can be used to design longitudinal biological data collection and how this can be used in the future by the UKHLS team.
