My current areas of research interest lie within the development of clinical pathways and patient care systems in the specialities of diabetes mellitus and acute medicine in Tallaght University Hospital (TUH). I have a busy clinical workload within the Acute Medical Unit, and couple this with specialty interest in Type 2 diabetes, so have developed research output focusing, initially on the development of care pathways for diabetic ketoacidosis, with regular audit and revision. This has lead to the introduction of new improved guidelines which are re-evaluated and updated regularly. In this work, I have been the senior investigator and lead, but have supervised undergraduate TCD medical students, as well as post-graduate doctors at both Senior House Officer and Registrar level to develop, undertake and analyse the audit material. I am now embarking on further development of the IV insulin provision within the ICU, in collaboration with my ICU colleagues in medical, nursing, pharmacy and dietetics fields. Again, this involved the supervision of undergraduate TCD students to undertake audit, and now develop a new protocol with ongoing involvement and implementation. Further plans for development of diabetes services within TUH include improved overall management of inpatients with Type 2 diabetes, utilising the limited international evidence there is on this cohort, with the intention to focus on such areas as steroid-induced hyperglycaemia management, and appropriate cessation and recommencement of diabetic medications for patients during their inpatient stay. My other area of research interest is in the development of the Acute Medical Unit in TUH, working in collaboration with my AMU colleagues and the rest of the Acute Floor. This has the potential to dramatically change the patient experience of acute medical presentations, and improve care and flow through the unscheduled care streams.
