Abstract
Introduction
National guidance suggests that all patients with neck of femur fractures (NOFF) should be mobilised day one post-operatively (NICE, 2023, QS16). This reduces rates of delirium, pneumonia and length of stay (Sallehuddin & Ong, Age and Ageing, 2021, 50, 356-357). Hypotension is a leading cause of immobilisation post-operatively. National guidance advises appropriate fluid resuscitation and review of polypharmacy when indicated (British Orthopaedic Association, 2007). This quality improvement project aimed to reduce post-operative hypotension and improve day one post-operative mobilisation in NOFF patients.
Method
Three months of NOFF patients were retrospectively reviewed pre-intervention. Those who did not receive surgical intervention were excluded. The proportion of NOFF patients that were unable to mobilise due to post-operative hypotension on day one was identified. We reviewed if intravenous fluids were given pre-operatively and if anti-hypertensives were held. An intervention was then implemented including educational posters and teaching sessions for doctors and nurses to encourage prescription of fluids on admission, holding of antihypertensives pre-operatively and detection and escalation of oliguria or hypotension post-operatively. Data were then re-collected in a three-month period post-intervention to ascertain if there was any change in practice.
Results
70 patients underwent NOFF repair pre-intervention compared to 54 patients post-intervention. There was a decrease in the proportion of patients unable to mobilise day one post-operatively due to hypotension from 15.7% pre-intervention to 9.3% post-intervention. There was an increase in the proportion of patients who received pre-operative intravenous fluids from 64.3% pre-intervention to 77.8% post-intervention. Of those patients who took anti-hypertensive medication, a higher proportion had this suspended pre-operatively, increasing from 82.9% pre-intervention to 88.2% post-intervention.
Conclusion
Simple educational interventions can reduce post-operative hypotension in NOFF patients. Developing local guidelines may facilitate persistent clinical change, as improvements following poster distribution and teaching sessions may be transient.
