Cardiovascular Diseases, Heart Failure
Conditions
Brief summary
The design included 152 patients with confirmed heart failure (HF) evaluated in two different periods of time: a baseline before the outbreak, and other during the outbreak of which 76 patients were randomized in each group. A care and follow-up guide was used as an instrument through a face-to-face survey (baseline group) and telemedicine (group outbreak). The primary outcome was the comparison of functional class modification observed in patients
Detailed description
Population and Data Sources All patients included, confirmed diagnosis of HF, according with the ESC guidelines criteria, both genders, above 18 years, who agreed to participate. All HF outpatients belonged to an open follow-up cohort of the HF clinic of the National Institute of Cardiology of Mexico, which started enrollment since September 2016. Periodic determinations were planned, clinical, functional, therapeutic evaluations, and emotional distress. The present design is a nested comparative analysis through a care and follow-up guide to HF patients. Data collection and outcomes Interventions were recorded in two groups of patients, who were randomly selected, in two different periods of time. The basal group was intervened from 15 May to 15 June 2019, a pandemic-free period. The outbreak group from 15 May to 15 June 2020, corresponding to increased activity of contagiousness and mortality associated with COVID-19, in general population in Mexico. Basal measurement was performed in a face to face method. In Outbreak period, under social isolation conditions, patients were evaluated by telephone. The assessments were performed out by medical staff with specialized training, with evaluations to which patients were accustomed by regular cohort assessments. The questions were ordered and systematized in a patient evaluation, care, and follow-up guide . A causality association question of emotional distress perception was added. Investigators recorded mortality and rehospitalization. The primary outcome was comparison of functional class modification, secondary outcomes were Clinical alterations related to HF worsening, Therapeutic modifications, Daily physical activities, and Self-perception of health status. The protocol conducted to hypothesize that the clinical alarm data reported by patients, in an alternative in-home model, with tele-medical assistance, is a useful tool in follow-up, as in detecting therapeutic performances, and associated with the HF deterioration. Protocol was approved by the ethics and investigational committees. All patients previously signed informed consent. Additionally, prior to the telephone survey, a verbal assent was requested. Absolute confidentiality of all patient data was declared.
Interventions
Interventions were recorded in two groups of patients, who were randomly selected, in two different periods of time. The basal group was intervened from 15 May to 15 June 2019, a pandemic-free period. The outbreak group from 15 May to 15 June 2020, corresponding to increased activity of contagiousness and mortality associated with COVID-19, in general population in Mexico14 Basal measurement was performed in a face to face method. In Outbreak period, under social isolation conditions, patients were evaluated by telephone. The assessments were performed out by medical staff with specialized training, with evaluations to which patients were accustomed by regular cohort assessments. The questions were ordered and systematized in a patient evaluation, care, and follow-up guide (appendix). A causality association question of emotional distress perception was added. We recorded mortality and rehospitalization
