Prospective Determination of COVID-19 Infection Rate in a Chemotherapy Unit in Mexico.

February 23, 2022 updated by: David Huitzil m, Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran

Prospective Determination of COVID-19 Infection Rate in Patients With Solid Tumors and Healthcare Workers of the Chemotherapy and Radiotherapy Unit at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador.

Cancer patients are considered vulnerable to COVID-19 infection. During the pandemic, cancer patients may need to continue their regular treatment of chemotherapy and / or radiotherapy and therefore must visit a hospital unit. As such, they may be at risk for SARS-CoV-2 infection by means of close contact to other patients and health care workers. Hospitals may implement policies to identify symptomatic subjects and limit their access to the chemotherapy / radiotherapy unit. However, asymptomatic COVID-19 positive patients may escape these filters and potentially be contagious to other patients and their health-related workers that care for other several patients. Therefore, there is a real risk of an outbreak that affects a particularly fragile patient population. Patients and their doctors need to know what is the risk associated to visiting a chemotherapy unit in order to decide if the risk outweighs the benefits of cancer treatment in their particular case. To date, this risk is unknown. The study will test patients and health care workers for COVID-19 infection during the peak of the pandemic in a chemotherapy unit in Mexico in order to determine this risk.

Study Overview

Status

Completed

Conditions

Detailed Description

In this is prospective cohort, patients with solid tumors and healthcare workers of the chemotherapy and radiotherapy unit at our center will be followed with a daily digital survey and optionally with biweekly PCR tests for SARS-CoV-2. People with symptoms and / or with a positive PCR test for SARS-CoV-2 will be notified and recommendations according to clinical state will be emitted.

Hypothesis: COVID-19 infection rate among patients with solid tumors treated with chemotherapy and / or radiotherapy will be less than 5% during the pandemic period.
