Chest infection linked to death after hip fracture surgery

Infection before surgery was linked to higher relative death rates than no infection, with adjusted hazard ratios of 2.68 at 30 days and 1.71 at one year.Infection before surgery was linked to higher relative death rates than no infection, with adjusted hazard ratios of 2.68 at 30 days and 1.71 at one year.
