161 CLEAR DISCHARGE PRESCRIBING IN STROKE PATIENTS: A RETROSPECTIVE AUDIT OF DUAL ANTIPLATELET DURATION AT FIRST FOLLOW-UP APPOINTMENT

Abstract

Abstract Background The risk of further ischaemic events post stroke and TIA is high in the following weeks. Short term treatment with Dual Anti-Platelet Therapy (DAPT) in appropriate patients has been shown to decrease the incidence of recurrent ischaemic events. However continuing DAPT longer than six weeks increases the risk of haemorrhagic complications. Methods Retrospective analysis of patients admitted to the Acute Stroke Unit over 4 months in a tertiary referral centre, reviewing discharge summaries and follow-up Outpatient Department (OPD) clinic letters on the online hospital computer system. Results We analysed data from 205 patients. 57 patients were discharged on DAPT. Of those, 18(31.6%) did not have a recommended duration of DAPT documented in their discharge summary. 40 patients returned to OPD for review, 16 patients had no documented follow-up, 11 were repatriated to a referring hospital for follow-up locally. The average time of OPD review was 4 months post discharge. Of those 40 patients who attended OPD follow up appointment, 33(82.5%) had documented evidence of a medication review in clinic. 9 of those patients (27.3%) were still inappropriately on DAPT, 5 of whom (55.6%) had no DAPT duration instructions documented in the discharge summary. Conclusion Treatment with DAPT puts patients at risk of haemorrhagic complications with longer term use. Clear documentation of treatment duration and communication with the patient and the patient’s GP is vital to ensure medication errors and unnecessary complications for the patient are avoided. Intervention: Following these results, we organised an education session for the Stroke Department staff and re-designed the stroke discharge summary template to highlight instructions on DAPT duration. We also emphasised the importance of communication with the patient’s GP and medication counselling with patients.
