A complex study requiring routine blood sampling for 63 patients across six sites in the UK including London, Midlands, Yorkshire and Scotland, two weekly for two years, visits alternating between hospital, outpatient and home.

The MRN trained 25 nurses to provide continual cover, including weekends and bank holidays. All centres utilising homecare achieved average recruitment of 11 patients per site over an 18 month recruitment period. One patient dropped out due to pregnancy. The centres which did not use home care recruited seven patients over the same time period, demonstrating in this case a 63% improvement in recruitment rates with home care.
