Technical Summary

Reliable assessment of the interplay of genetic and major lifestyle factors in common diseases requires particularly large studies: for example, study of 0.5M healthy adults in the #60M UK Biobank study should yield 10,000 incident cases of myocardial infarction for analyses after several years of follow-up. The current proposal is for a pilot study to determine the feasibility and acceptability of establishing large bioresources by involving individuals accessing health services for other purposes. IN particular, it is proposed to explore linkage of: (i) millions of blood samples collected through the NHS blood and transplant (NHSBT, formerly the National Blood Service), and (ii) disease outcomes recorded in electronic records, notably the Myocardial Infarction National Audit Project. The proposed pilot study will focus on: (i) the potential impact of health questionnaires, genetic studies and data linkage on blood donation (i.e., assessment of acceptability to blood donors and to the NHSBT), (ii) feasibility of database linkage, and (iii) processing and storage of biological material. In addition to informing decisions about the potential conduct of a large study of blood donors, this pilot study should yield generalisable knowledge about the potential for embedding aspects of population health research into routine health services.
 
Description COMPARE study
Geographic Reach National 
Policy Influence Type Influenced training of practitioners or researchers
Impact The COMPARE study provided NHS Blood and Transplant with the first evidence from a randomised trial (of 30,000 blood donors) as to the most effective way to measure haemoglobin (Hb) levels in blood donors and the effects on the health service and quality of life/health of blood donors of the different methods of Hb measurement and the consequential levels of incorrect bleeding or deferral.
 
Description INTERVAL study
Geographic Reach National 
Policy Influence Type Influenced training of practitioners or researchers
Impact The INTERVAL study provided NHS Blood and Transplant with the first data from a randomised trial of the effects of different blood donation intervals. The quantitative data produced from INTERVAL (and published in The Lancet) include data on the amount of blood collected from donors and the health and well being of blood donors and will inform NHSBT policy on blood donation strategies and policy.
 
Title COMPARE 
Description COMPARE is a study of 30,000 English blood donors set up to determine for NHS Blood and Transplant the most effective way of measuring haemaglobin levels in blood donors. Additionally, participants in the study have consented to have the blood samples used in research and data from genetic and biomarker assays and through linkage with electronic health records will be used across a range of research projects.

Title INTERVAL Bioresource 
Description INTERVAL is a randomised controlled trial in up to 50,000 whole-blood donors recruited at 25 locations across England. Participants are involved in a two-year intervention during which they are invited to give blood either at usual donation intervals or more often. The primary aim of the intervention is to establish whether donors can safely and acceptably give blood more often than is now collected by NHS Blood and Transplant. A further aim of INTERVAL is to create a national epidemiological bioresource, including a recall-by-genotype (phenotype) resource, which will enable detailed study of the health of blood donors and broader public health and biomedical issues. Participant recruitment commenced in June 2012. Our target of 50,000 study participants was reached two years later, in June 2014. Participants have consented to: use of their data and biological samples for a wide range of analyses, invitation to further biomedical studies, and long-term linkage to e-health records. Funding that has been awarded from NHSBT and NIHR will allow the study of the following factors in 50,000 participants i) extended haematological profile (>200 parameters) ii) lifestyle profiling, including assessment of smoking, alcohol consumption, dietary intake, and, in large subsets, monitoring of physical activity through the use of worn accelerometry devices; (iii) cognitive function traits related to different domains of mental function and well-being; and (iv) linkage with e-health records, eg, various morbidity registers, hospital discharge records (v) a novel gene array containing 850,000 single nucleotide variants (SNVs), which includes many functional SNVs and a GWAS scaffold to deliver imputation of ~20 million variants; (vi) ~200 candidate biomarkers related to haematological traits and other pathways for a wide range of disease processes (eg, liver and renal function; autoimmunity; hormonal status).

Impact Serum samples collected during the study have been used to measure the levels of ferritin in participants. DNA has been used in a genome-wide association study of haemoglobin concentration and related parameters, and genotyping of the HFE gene.
