摘要
We have studied the mortality after total hip replacement (THR) of 39,543 patients, having a mean age of 69 years, who were reported to the Norwegian Ar- throplasty Register. The median follow-up time was 5.2 (0-10.4) years. 323 of 6201 deaths occurred during the first 60 postoperative days. The patient mortality was compared with the mortality in the Norwegian popula- tion, using standardized mortality ratios (SMR). The SMRs were compared and adjusted for age, gender, and other possible confounders in a Cox regression model in- corporating the population mortality. We observed a lower mortality in patients with THR than in the Norwegian population (8-year patient mor- tality was 25%, versus 30% in the corresponding Nor- wegian population. SMR†= 0.81). There was an in- creased standardized mortality ratio in patients less than 50 years (SMR†= 2.50), patients 50-59 years (SMR†= 1.16), patients with THR due to rheumatoid ar- thritis (SMR†= 1.48), and patients with femoral neck fracture (SMR†= 1.11). The SMR decreased with in- creasing age at the time of THR surgery. After revi- sion surgery, the SMR was similar to that after the first primary operation, whereas a second primary operation in the opposite hip was associated with a further reduction in the SMR (SMR†= 0.65). During the first 60 postoperative days, all patient categories had a higher mortality than the general population (0.8% mortality, SMR†= 1.39). n
