Objective: To assess the factors which result in increased mortality following a femoral neck fracture.

Design: Patients were sequentially recruited on admission to the fracture units and followed up at 2 weeks, 3 months, 6 months and 1 year.

Setting: The fracture units of two major Belfast teaching hospitals, The Royal Victoria and Belfast City Hospital (which have since amalgamated)

Subjects: All patients over the age of 65 years between 27th October 1997 and 30th November 1998 and who were admitted to the fracture units within 28 days of having sustained a fracture.

Outcome measures: Patients were assessed by: Barthel score, mental score, home circumstances. Mobility and mortality

Results: 748 patients (male/female 153/595). Mean age 82.1 years ± s.d. 7.4 years.

The overall 1-year mortality was 31.4% (235/748) and the sex distribution (male 73/153 [47.7%] female 162/595 [27.2%]).

27/748 patients who did not undergo surgical intervention had a 1-year mortality of 85.2%.

Factors which were associated with an increased 1 year mortality were: male sex (p< 0.0005), High ASA score (p< 0.0005), low Barthel score (p< 0.0005), poor mental score (p< 0.0005), decreased mobility (p< 0.0005), increased dependency in home circumstances (p< 0.0005), increased age (p< 0.0005), increased delay to surgery (p< 0.0005) and living alone (p< 0.0005).

Marital status, fracture type and type of operative intervention had no statistical effect on mortality.

Using logistic regression male sex, high ASA score, increased age, increased delay to surgery and poor mental score all remained independently associated with an increased mortality at 1 year.

Conclusion: The majority of factors which are associated with increased mortality following a femoral neck fracture are outside our control, namely age, sex and mental score. It should however be possible to reduce surgical delay and improve the patients pre-operative medical status (ASA score). A balance has to be struck between optimisation of the patient and delaying surgery unduly. The optimal timing of surgery requires further investigation.
