Review of Irish patients meeting ST elevation criteria during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic has seen the introduction of important public health measures to minimise the spread of the virus. We aim to identify the impact government restrictions and hospital-based infection control procedures on ST elevation myocardial infarction (STEMI) care during the COVID-19 pandemic.

Methods: Patients meeting ST elevation criteria and undergoing primary percutaneous coronary intervention from 27 March 2020, the day initial national lockdown measures were announced in Ireland, were included in the study. Patients presenting after the lockdown period, from 18 May to 31 June 2020, were also examined. Time from symptom onset to first medical contact (FMC), transfer time and time of wire cross was noted. Additionally, patient characteristics, left ventricular ejection fraction, mortality and biochemical parameters were documented. Outcomes and characteristics were compared against a control group of patients meeting ST elevation criteria during the month of January.

Results: A total of 42 patients presented with STEMI during the lockdown period. A significant increase in total ischaemic time (TIT) was noted versus controls (8.81 hours (±16.4) vs 2.99 hours (±1.39), p=0.03), with increases driven largely by delays in seeking FMC (7.13 hours (±16.4) vs 1.98 hours (±1.46), p=0.049). TIT remained significantly elevated during the postlockdown period (6.1 hours (±5.3), p=0.05), however, an improvement in patient delays was seen versus the control group (3.99 hours (±4.5), p=0.06). There was no difference seen in transfer times and door to wire cross time during lockdown, however, a significant increase in transfer times was seen postlockdown versus controls (1.81 hours (±1.0) vs 1.1 hours (±0.87), p=0.004).

Conclusion: A significant increase in TIT was seen during the lockdown period driven mainly by patient factors highlighting the significance of public health messages on public perception. Additionally, a significant delay in transfer times to our centre was seen postlockdown.

Trends in the treatment of chronic kidney disease-associated anaemia in a cohort of haemodialysis patients: the Irish experience.

Ir J Med Sci 2019 Feb 27;188(1):223-230. Epub 2018 Apr 27.

Background: Anaemia among haemodialysis patients is treated with iron and erythropoietin-stimulating agents (ESAs). ESAs reduce requirements for blood transfusions but are also expensive and overzealous use may be associated with adverse outcomes. Recent international trends have been characterised by reduced ESA doses and a greater reliance on intravenous (IV) iron. We determined trends in prescribing patterns of ESAs and IV iron for the treatment of anaemia in two representative Irish dialysis centres and correlated with current guidelines and international trends.

Methods: Patient data was accessed from the Kidney Disease Clinical Patient Management System (KDCPMS) for the period 2012 to 2014. We generated reports on ESA and iron doses, lab data (haemoglobin (Hb), transferrin saturation (TSAT) and ferritin) and patient population characteristics. We mapped the trends in ESA, iron dosing and lab parameters achieved. A linear mixed model determined the significance of these trends over time.

Results: ESA dosing became lower in the second, third and fourth quarters of 2014. Dosing of iron increased throughout but a large increase was seen in the third and fourth quarters of 2014. Ferritin levels decreased and TSAT and haemoglobin levels increased. Changes in iron dosing were significant with p value of < 0.05.

Conclusions: Our findings are consistent with recent global trends toward increasing iron use. Such trends may have economic implications given the high cost of ESAs and the relative affordability of iron. In addition, the potential harm of excessive iron dosing may need to be considered.
