Abstract
Aims
This retrospective study aimed to determine the causes of in-hospital death after Neck of Femur (NOF) fracture in Southampton General Hospital (SGH) over a 6 year period, comparing the clinical cause of death with findings at post-mortem. A previous study showed discrepancies between pre-mortem clinical diagnosis and autopsy findings after in-hospital deaths in SGH.
Methods
The study included all patients who died in SGH after NOF fracture from 2007–2013. Case notes were reviewed to determine the pre-mortem clinical diagnosis and compared with the autopsy findings to analyse major and minor discrepancies. Data were also analysed from the period 1997–2003 in order to compare the causes of death.
Results
43 cases were referred for autopsy after NOF fracture during the 6 year study period, of which 39 cases (90.1%) were available for analysis. There was complete agreement between pre-mortem clinical diagnosis and autopsy findings in 64.1% of cases. Major discrepancies were found in 35.9% of cases and minor discrepancies in 23.1% of cases. Causes of death due to bronchopneumonia and pulmonary embolism had decreased significantly during the recent 6 year period when compared with the previous study period. No pulmonary emboli were identified as the primary causes of death between 2007 and 2013.
Conclusion
Deaths due to pulmonary emboli after NOF have declined significantly. The reasons for this are unclear and are the subject of an ongoing study which will be discussed. Discrepancies between pre- and post-mortem diagnoses highlight the importance of autopsy findings. The current study revealed a similar rate of major discrepancies compared to the previous study.
