Text: the proposed research will obtain data from 400 patients with chronic obstructive pulmonary disease and 100 of their caregivers from new york city and chicago, il. the final dataset will include self-reported data on demographic characteristics, disease-severity, self-management behaviors, cognition, and health literacy, as well as medication and disease data obtained from electronic records abstractions. given that we will have data linking caregivers with patients, and patients to specific hospitals and hospitalization events, there is a remote possibility of deductive disclosure of subjects, even after de-identifying the dataset. thus, we will make the data and associated documentation available to users only under a data-sharing agreement that provides for: (1) a commitment to using the data only for research purposes and not to identify any individual participant; (2) a commitment to securing the data using appropriate computer technology; and (3) a commitment to destroying or returning the data after analyses are completed. the data underlying this specific study will be available on request at the time of publication. juan p wisnivesky may be contacted if data is requested.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
