Impact of the Covid-19 pandemic on the device therapy for patients with the heart failure

Abstract

\n \n \n Hospital admissions of patients with cardiovascular disease were markedly reduced in the UK in 2020 during the Covid-19 pandemic. In many institutions, including ours, patient care was redistributed from a specialty-based approach to a ward-based system, meaning some patients being admitted and managed under the care of non-specialist teams.\n \n \n \n We wished to examine the impact of these changes on heart failure (HF) patients presenting during the pandemic and on appropriate delivery of complex device therapies.\n \n \n \n The study was undertaken in a large UK teaching hospital. The institution audit programme includes cardiac device therapy provision, aiming to ensure that implantable cardioverter defibrillators and cardiac resynchronisation therapy are offered to the target population in accordance with NICE guidance [Technology Appraisal 314]. In accordance with the guidance, patients admitted to hospital with serious ventricular arrhythmia, familial cardiac condition with high risk of sudden cardiac death (SCD), surgical repair of congenital heart disease (CHD) and patients with HF and LVEF<36% were identified from hospital coding. Findings during the pandemic (March to August 2020) were compared with the same period in 2019. Fisher s exact test was used to compare proportions.\n \n \n \n Among non-HF patients, device therapy prescription was consistent in the two periods observed. Table 1 shows how many patients were eligible for device therapy and how many were offered it. Table 2 contains details of HF admissions, showing an 8% reduction in admissions during the pandemic. The proportion of patients eligible for device therapy did not change significantly. However, there was a significant reduction in the proportion of eligible patients who were offered device therapy (79% vs 94% p=0.03). In addition, during the pandemic there was a trend towards a greater chance of patients being considered too frail for device therapy (p=0.08). Among 12 patients overlooked for device therapy, 10 were not under the care of Cardiology. Among 31 patients considered too frail for device therapy, 26 were not under the care of Cardiology.\n \n \n \n During the Covid-19 pandemic, a modest reduction in HF hospital admission was observed with a marked fall in identification of patients eligible for device therapy. Possible explanations include intense pressure to discharge patients quickly, an increased perception of patient frailty during a crisis and the lack of recognition of indications for device therapy when patients are under the care of non-specialists. These findings suggest that cardiac services should actively look for HF patients who may have missed out on life-saving device therapies during the pandemic.\n \n \n \n Type of funding sources: None.\n
