Allocation of priorities for public health research and policy requires quantification of the relative impact of health problems. Methods include disability weights, which measure the level of disability for a health state, and utility weights, which estimate the effect on quality of life with a lower utility weight associated with greater loss in quality of life. These values have been calculated for few orthopaedic conditions. This study aims to calculate the disability weight and country-specific utility weights for Developmental Dysplasia of the Hip (DDH). Participants were fully licensed Orthopedic surgeons contacted through national and international Orthopedic organizations. A survey utilised three exercises to estimate disability weight of DDH: preference-ranking exercise, time trade-off exercise and visual analogue scale. A global disability weight was calculated using a random effects model through an inverse-variance approach. A country-specific utility weight was calculated as 1 minus the country-specific disability weight given by the time trade-off exercise and visual analogue scale. 181 surgeons participated over four months with 116 surgeons included in the final analysis. The global disability weight for DDH was calculated to be 0.18 (range, 0.11 to 0.24). Compared to other musculoskeletal conditions, this disability weight falls between amputation of one leg (disability weight: 0.173) and severe neck pain (disability weight: 0.229). Country-specific utility weights for DDH ranged from 0.26 in Morocco to 0.89 in Finland. This is the first time that a global disability weight and utility weights have been estimated for DDH. The methodology may be applied to other surgical conditions.
