Routine Data "routine data" is data collected as byproducts of clinical care by the clinician and as an integral part of the process of care. Williams JG, BMJ 1995;310;665-666 Secondary data : collected by someone else then used by researcher
From birth to death
Why use routine data? Already collected in many different healthcare and administrative settings Collection process not intrusive to target population Retrospective data available which is regularly updated Studies can be done now Costs of using data lower than for prospective collection Potential for datasets to be linked giving rich source of information about large numbers of patients with different conditions across diverse geographical and healthcare settings Collected in a consistent way Ethical and consent issues can be less problematic
Epidemiology Identify patients with specific disease or taking a specific treatment Use hospitalisations and death data to build-up clinical histories and investigate outcomes Support clinical trials Support feasibility studies and patient recruitment Passive follow-up of subjects : cheaper, maximises follow-up Support other research methods Cross-sectoral linkage Act as sampling frame for qualitative studies Research Using Routinely Collected Data
Women with breast cancer using endocrine therapy were missing tablets Study: Linking prescribing records to hospital discharge, cancer registry, cancer clinic data and mortality records Results: Low adherence was associated with poorer survival (HR=1.20; 95% CI=1.03 1.40, P=0.019) Adherence to medication in women with breast cancer
WOSCOPS follow-up % Landmark trial of statin use in patients with no previous CHD Study: Use record linkage of trial data to hospital discharge, cancer registry, and mortality records Results: 0 5 10 15 20 25 30 Placebo Pravastatin 0 2 4 6 8 10 12 14 16 Years since randomisation CHD death or CHD event
Cancer Screening in Women in Glasgow Lower uptake of bowel screening in women than for breast or cervical screening Study: Link screening records and examine difference in characteristics for uptake. Invite women for interview to explain why they use other cancer screening services but not bowel National Awareness and Early Diagnosis Initiative (NAEDI)
