National guidelines suggest which investigations should be performed for patients admitted with an acute hip fracture. We have observed practice often deviates from these guidelines. Our study aims to identify the incidence of deviation with regards to blood investigations and review the effect of deviation on management, and the financial burden on the healthcare system.

A total of 250 acute hip fracture admissions over 12-months period reviewed retrospectively. Admission blood tests, time of presentation, and time of operation were recorded. The cost of admission blood investigations was calculated.

Seventy-nine percent of admissions had one or more non-routine blood investigation tested. Twenty-Nine percent of these tests had abnormal results and these were found to be clinically relevant in 6% of patients. The most commonly requested non-routine investigations were: LFT in 79%, Coagulation screen in 56%, and CRP in 48%. Fifteen percent of patients did not have surgery within the time frame of 36 hours. The total cost of non-routine investigations was £1995.04.

Deviation from admission investigations guidelines for hip fractures without clinical indication adds little clinical value, has no effect on management, and can be a potential cause of unnecessary investigations. This in turn leads to further delays and extra costs.
