Mortality after Hip Fractures
Open accessAbstract
A survey was made of 1592 patients, over the age of 50 years, who had sustained a fracture of the hip. The mean age was found to be 77 years, and 76.9 per cent (1224/1592) of the patients were women. Trochanteric fractures accounted for 52.5 per cent (836/1592) of the cases and these patients had a higher mean age than those with femoral neck fractures. The average hospitalization time was 24 days and the mortality during the hospital stay was 8.6 per cent (137/1592). Statistical analysis revealed that the hospital mortality rate was related exclusively to the age and the sex. The mortality after 3 months was 17 per cent and that after 6 months 21.5 per cent. The survival rates paralleled the expected rate after 1.6 years but were found to be higher than expected after 2.8 years. The mortality after 1 year was 27 per cent, after 3 years 43 per cent and after 5 years 56 per cent.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
