The influence of social deprivation on bone donation: a 10 year retrospective study
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.
