ABSTRACT
BACKGROUND: Reconfiguration of the Irish acute hospital sector resulted in the establishment of a Medical Assessment Unit (MAU) in Mallow General Hospital (MGH). We developed a protocol whereby certain patients deemed to be low risk for clinical deterioration could be brought by the National Ambulance Service (NAS) to the MAU following a 999 or 112 call. AIMS: The aim of this paper is to report on the initial experience of this quality improvement initiative. METHODS: The Plan-Do-Study-Act (PDSA) Cycle for quality improvement was implemented when undertaking this project. A pathway was established whereby, following discussion between paramedic and physician, patients for whom a 999 or 112 call had been made could be brought directly to the MAU in MGH. Strict inclusion and exclusion criteria were agreed. The protocol was implemented from the 1st of September 2022 for a 3-month pilot period. RESULTS: Of 39 patients discussed, 29 were accepted for review in the MAU. One of the 29 accepted patients declined transfer to MAU. Of 28 patients reviewed in the MAU, 7 were discharged home. One patient required same day transfer to a model 4 centre. Twenty patients were admitted to MGH with an average length of stay of 8 days. Frailty and falls accounted for 7 of the admissions and the mean length of stay for these patients was 12 days. CONCLUSIONS: Our results have demonstrated the safety, feasibility and effectiveness of this pathway. With increased resourcing, upscaling of this initiative is possible and should be considered.

OBJECTIVES: The goal of this study was to identify the factors responsible for embolic complications of direct current (DC) cardioversion of atrial arrhythmias. BACKGROUND: Direct current cardioversion of atrial fibrillation (AF) carries a risk of thromboembolism, which is reduced, but not eliminated, by anticoagulation. The risk of embolism after conversion of atrial flutter is believed to be lower. No series to date has included enough patients receiving anticoagulants or enough patients with atrial flutter to estimate the risk in these groups. METHODS: We reviewed the case records of 1,950 patients who underwent 2,639 attempts at DC cardioversion. RESULTS: Cardioversion was performed within two days of the apparent onset of the arrhythmia in 443 episodes, 352 without subsequent prolonged anticoagulation with one embolic complication. Cardioversion was preceded by warfarin therapy for > or = 3 weeks in 1,932 instances. No embolic complication occurred in 779 attempts performed with an international normalized ratio (INR) of > or = 2.5 (95% confidence limits 0% to 0.48%). Of 756 cases in which the INR was <2.5 or was not measured before conversion, nine were complicated by thromboembolism. Embolism was significantly more common at an INR of 1.5 to 2.4 than at an INR > or = 2.5 (0.93% vs. 0%, p = 0.012). The incidence of embolism after conversion of atrial flutter or tachycardia was similar to that after cardioversion of AF (0.72% vs. 0.46%, p = NS). CONCLUSIONS: The INR should be > or = 2.5 at the time of cardioversion if the duration of AF is uncertain or >2 days. Cardioversion of atrial flutter presents similar risks and requires similar anticoagulation.
