Abstract:
|
Over the past decades the medical field developed rapidly. Emergence of new tests and technologies altered treatment and care patterns. Surveys collecting data over a long time have to respond to these changes. Responsive survey design refers to design with multiple phases, with each phase implementing a different survey. The changes in these surveys include the emergence of new survey questions, or refinement of existing ones, and hence results in data missing by design We propose a tailored multiple imputation approach that allows to combine different phases of survey data into a single data set for analysis purposes. The Individualized Cancer Care Study is a multi-phase study conducting surveys to examine breast cancer treatment experiences and decision making in year 2013-2015. We use this study to demonstrate our multiple imputation approach which consists of three stages: imputation of common variables, stratifying subjects on their propensity being surveyed on the later phase, and imputation of phase-specific variables and imputation of missing values arisen from combining different but related questions between phases.
