Key result
A preoperative risk assessment system effectively stratified hospitalization mortality risk in surgically treated hip fractures, with rates of 2.5%, 11.9%, and 44.1% across three risk groups.
Why the study?
Does a preoperative risk assessment system accurately predict mortality and medical complications in patients with surgically treated hip fractures?
Observational (n=317)
Does a preoperative risk assessment system accurately predict mortality and medical complications in patients with surgically treated hip fractures?
A preoperative risk assessment system based on routine clinical data effectively stratifies patients with surgically treated hip fractures into distinct risk groups for in-hospital mortality and medical complications.
May inform preoperative counseling in hip fracture surgery; leaves open prospective validation before practice change.
There have appeared no objective means by which preoperative risk in patients with fractures of the hip can be quantitatively predicted. The developed risk's core is based on medical history, physical examination, chest radiograph, and screening laboratory data. This system reproducibly assigns patients into one of three groups. Three hundred seventeen patients with surgically treated hip fractures (93 femoral head, 166 neck, 58 intertrochanteric fractures) were analyzed in this study. Surgical treatment included 102 Ender-pinnings, 43 Böhler-nails, 79 dynamic hip screws, and 93 endoprostheses of the hip (according to fracture type). Overall mortality rate during hospitalization was 9.5%. The mortality rate in Group I was 2.5%; in Group II, 11.9%; and in Group III, 44.1%. The medical complications in Group I were 12.6%; in Group II, 28.6%; and in Group III, 67.6%. The difference for each group was significant. This preoperative risk assessment appears effective in more accurately identifying patient risk.

Miller et al. (1993) conducted an observational in Surgically treated hip fractures (n=317). Preoperative risk assessment system was evaluated on Mortality rate during hospitalization. A preoperative risk assessment system effectively stratified hospitalization mortality risk in surgically treated hip fractures, with rates of 2.5%, 11.9%, and 44.1% across three risk groups.
