Effects of COVID-19 Pandemic on Personal and Public Health and Functioning of Health Care System: Case Study of the CirculatORy System in LiThuania

Brief Summary

Detailed Description

COVID-19 pandemic has greatly affected the world and changed health care in almost every country. During the spring of 2020, first pandemic wave was of different scale in different countries. In countries affected by the virus the most, a majority of the studies focused on the direct impact of COVID-19 on community health. It was noticed promptly that the novel virus is especially high-risk for patients with cardiovascular comorbidities. Furthermore, the collateral damage of COVID-19 pandemic on the provision of cardiovascular (CV) care and cardiovascular mortality was also reported early in several nationwide and selected cohort studies. The research was mostly focused on acute cardiovascular conditions; changes in hospital admissions and early mortality after myocardial infarction were also often analysed. Meanwhile, a substantial proportion of routine appointments, diagnostic and therapeutic procedures was cancelled. Data on the changes in total national CV services, including out- and in-patient health care facilities, acute and chronic conditions, during the outbreak, between the two pandemic waves and onwards are scarce. First case of COVID-19 in Lithuania was confirmed on 28th February 2020. First nationwide quarantine was introduced by Lithuanian government on 16th March and ended on 16th June. In that period, although Lithuania was reported among the least affected countries according to World Health Organization - 1 773 COVID-19 cases were recorded and 86 patients (of whom 10 patients died from other causes after testing positive for SARS-CoV-2) had died before the end of quarantine, Lithuanian government limited contact appointments to urgent conditions only. The utmost efforts to provide triage, follow-up care by telephone call and e-prescriptions were recommended. This greatly affected availability of cardiovascular care. The second pandemic wave in Lithuania was substantially more severe. Consequently, the second nationwide quarantine was implemented on 7th November, 2020. Contact appointments were not limited by the government; however, the scope of CV care was again negatively affected, mostly by the strained health care system. We analysed the indirect impact of the COVID-19 pandemic in a country, which was hit by two very different pandemic waves. The objectives of this population-based study were: (1) to assess the impact of the COVID-19 pandemic on CV care (2) to compare rates of outpatient care visits and hospitalisations of cardiovascular patients in different periods of 2019 and 2020 (3) to compare the rates of CV mortality in Lithuania in different periods of 2019 and 2020 (4) to investigate sex and age differences in CV care and CV mortality

Primary Outcomes

Secondary Outcomes

• Evaluation of sex and age differences in changes of CV care provision and CV deaths during the pandemic and comparison between 2019 and 2020(2 years)
• In-hospital mortality rates in Lithuania in 2019 and 2020(2 years)
• Comparison of distribution of death places in Lithuania in 2019 and 2020(2 years)
• Comparison of all-cause mortality during the hospital stay and at 3 months of follow-up in patients presenting to a tertiary care centre with acute coronary syndrome during the first quarantine in 2020 and in a corresponding period of 2019(3 months)
