Home therapy pathway - safe and streamlined method of initial management of ankle fractures.

BACKGROUND

Ankle fractures requiring operative fixation often swell up after 24h and surgery during this period is not feasible as there are several associated risks including infection and wound breakdown. The affected limb is kept elevated usually in hospital and once the swelling has sufficiently subsided then the operation takes place. We conducted a study looking at the impact of a home therapy ankle pathway on the length of stay and safety of patients with ankle fractures requiring surgical fixation.

METHODS

The length of stay of a control group was studied from December 2009 to March 2010. The home therapy ankle pathway was then introduced in August 2010. If patients could not have their operation within 24h then they were placed in a Plaster of Paris back slab in casualty with the ankle reduced, limb care advice given - elevation, cooling and DVT thromboprophylaxis - and the patient was discharged home on crutches after a slot was determined on the trauma list typically six days later. The patient was also given an emergency contact number in case an untoward event occurred, and they were called at least once during their home stay by hospital staff to ensure all was well. Patients who were unsafe to be discharged on home therapy were admitted. This cohort of patients was studied between August 2010 and December 2011 RESULTS: In the control group, 49 ankle fractures required operative intervention. The mean pre-operative length of stay was 2.88 days and the mean post op length of stay was 5 days. Between August 2010 and December 2011, after implementation of the pathway, 176 ankle fractures requiring operative treatment presented to the orthopaedic department. Of these, 105 were eligible for home therapy on the ankle pathway prior to surgery. The average pre-operative length of stay on the pathway was 0.17 days. The average post op length of stay was 1.72 days (P<0.001 in all modalities). Home therapy was carried out for an average of 6.63 days. Challenges of home therapy included persistent swelling and blistering (11), loss of reduction (4), poor pain management whilst at home (4) and cancellation due to lack of availability of a theatre slot (6).

CONCLUSION

With patients in whom it is indicated, the home therapy ankle pathway has proved to be a safe and resource sparing method of managing ankle fractures prior to surgery.
