“…These 2 cost effectiveness can be analyzed and the difference between them is the ICER (difference in costs by the difference in effectiveness). Probability of femoral neck fracture complications 0.200 0.00 0.50 1-6, 9, 12, 13, 16-20 Probability of reconstruction nail complications 0.010 0.00 0.02 16,22 Probability of death from femur fracture 0.035 0.00 0.10 21 Probability of missed femoral neck fracture 0.370 0.00 0.60 1-6, 9, 12, 13, 16-20 Probability of ipsilateral hip fracture 0.068 0.00 0.20 1-6, 9, 12, 13, 16-20 Utilities Reconstruction nail 0.969 0.800 1.000 16,27 Reconstruction nail complications 0.820 0.500 1.000 12,16,27 Complications such as a revision of an endoprosthesis. The authors assumed that the morbidity associated with the above major complications would be a disutility of 0.3 or 24 weeks at 0.5 QALY.…”
