Abstract
An audit identifying all surgical bone donors over a 10 year period was conducted. Postcodes were used to link data from the index of multiple deprivation (IMD) 2007 to give each donor a deprivation score. An audit from 2000 to 2010 of primary total hip replacement (THR) patients was also conducted, and similarly a deprivation score was identified for each patient. IMD scores are split into quintiles. A high IMD score indicates a high degree of social deprivation. Conversely low IMD scores indicate a more affluent community. The mean IMD 2007 score was 13.36 (95% CI 13.12-13.60). The national mean IMD score is 21.7 (CI 21.52-21.88). The difference is significant (p < 0.0001). The mean IMD 2007 score of primary THR patients identified in the arthroplasty database was 19.19 (CI 19.00-19.38). The difference between the mean arthroplasty score and the mean score of donors is significant (p < 0.0001). The donation rate increases as social deprivation decreases from quintile to quintile in both: the older patients (CI 1.08-1.14; p < 0.0001) and the general population (CI 1.20-1.25; p < 0.0001). Bone donors are substantially less deprived than their donor pool of THR patients. Donor rates are consistently lower in quintiles which are more deprived.
