The Extended Salford Lung Study (“Ex-SLS”) Data Access Project

Overview

The Salford Lung Study (SLS) subjects represent a group of COPD and asthma patients whose disease is extremely well-characterised over a short time period. Subjects in the SLS originally consented for information relevant to the study to be shared with the sponsor (GSK). These data were limited to three years prior to randomisation and the twelve-month interventional treatment period. Broadened access to patients' data would allow SLS subjects' entire disease journey to be researched, presenting a rare opportunity to improve scientific and clinical understanding of COPD/asthma disease risk, treatment and progression. This proposal seeks to collect additional subject-level data from SLS patients via their electronic medical records (encompassing past and future data for up to 10 years from the date of consent) and via a one-off patient questionnaire administered at the time of consent.

Clinical Trial Outcome Measures

Primary Measures

  • Retrospective EMR data
    • Time Frame: Up to 10 years
    • All historical data from consent until the beginning of patients’ electronic health records, encompassing all routinely-available electronic demographic and health-related data back to a patients’ earliest available electronic record.
  • Prospective EMR data
    • Time Frame: Up to 10 years
    • Prospective longitudinal data, encompassing collection of future routinely-recorded electronic demographic and health-related data for a period of ten years from this consent or until a patient is either lost to follow up or at the time of their death.
  • Risk factor questionnaire
    • Time Frame: Up to 10 years
    • Historical demographic, COPD/asthma risk factor information and clinical data not routinely available. Collected via paper questionnaire.
