The probability of death following a fracture of the hip

Abstract

All patients 45 years of age and over admitted with fractures of the hip to hospitals in the Atlantic Health Region of Nova Scotia were followed up over a two-year period. Actuarial methods were used to estimate survivorship from the date of fracture in 202 patients.Over-all, it was estimated that only 63.8% would be alive by one year post-fracture. This is 70% of the survival rate expected in the general population of corresponding age and sex. The period of greatest mortality was within the first 12 weeks. Patients surviving to one year could be considered "cured", for after that their survivorship was at least as favourable as that of the "normal" population.Mortality was greatest in males in those 75 years of age and over and especially in patients who were relatively immobilized prior to their fracture. In this "dependent" group the relative survival ratio at one year was only 38%.
