Abstract
Background: Ankle fractures are the second commonest lower limb fractures after hip fractures and as opposed to the latter occur commonly in younger population of working age. Due to a host of different factors including the state of soft tissues and delayed presentation, there is often a delay of several days between fracture and operation, resulting in longer admissions. It is hypothesised that early intervention may shorten hospital stay and hence save on hospital resources.
Aims: To ascertain the impact of timing of ankle fracture surgery on length of post operative and total hospital stay and its implication on resources.
Methodology: Consecutive ankle fractures that underwent open reduction and internal fixation at Newcastle General Hospital over a 4-year period were studied as a retrospective cohort. Data collection from Theatre records, PAS system, case notes and radiographs was undertaken and entered in SPSS database.
Results: 431 cases of ankle fracture open reduction and internal fixation were included in the study. 41% were female and 59% were male patients, with a mean age of 39.1 years (SD±17.8), with age range from 16 to 89 years.
298 patients were operated within 48 hours of admission (early surgery group), and 136 patients after 48 hours (delayed surgery group). The mean hospital stay in the early operation group was mean 5.3 days (SD±4.9) and in the delayed surgery group it was 12.2 days (SD±8.4). The patients who were operated early had shorter total hospital stay (p< 0.001) and also had shorter post-operative stay (p< 0.05). Increasing age and female gender appeared to predispose to longer hospital stay but this was not statistically significant. Mean age, gender and ASA grade, fracture class and operating surgeon’s grade distribution were not significantly different in the early and late surgery groups.
Each patient in delayed surgery group spent an extra 6.9 days in hospital stay compared to the early surgery group, translating into an extra 937 hospital bed days. The average extra cost of hospital stay per case in the delayed surgery group (£1414) exceeds the average expense of surgery per case in that group. The delayed surgery group resulted in added expenditure of £192085 to the trauma division solely for extra hospital stay.
Conclusion: Timing of surgery in ankle fracture appears to be the most significant determinant affecting the hospital stay. This has a significant resource implication, financially and in freeing up of hospital resources, as well as impacting on the lives of this large group of patients.
