e18807 Background:Since December 2019, the world is facing a pandemic caused by a novel coronavirus (SARS-CoV-2). We sought to analyze the behavior of cancer treatments and procedures in breast cancer in Brazil after the beginning of the COVID-19 pandemic through an artificial intelligence platform with real life data. Methods:Data evaluation was performed using the TechTrials platform. This platform created a unique healthcare data warehouse containing hundreds of different publicly available data sources about Brazilian Public Health System and with proprietary technology, developed several analytics products that explore and release real-world data (RWD) insights. For this analysis data were extracted from DATASUS – SIA (outpatients information system). For each outcome, data from January 2011 to February 2020 were used to adjust a time series to predict values for March to November 2020. Those values were compared with the observed ones. Results: Biopsies, mammograms and procedures showed a sharp decrease (41.9%, 73.7% and 31.1%, respectively), in April 2020 (following month of the first COVID-19 case in Brazil) with some recovering in the following months. All observed values of biopsies, the number of mammograms from March to October and the number of procedures in April and May were significantly smaller than the predicted ones. Number of women undergoing chemotherapy began to decline in August and remained falling until the last month of available data.(Table). Conclusions: This study is the first one that analyzes RWD of breast cancer screening, diagnosis and treatment in Brazil as a result of the COVID-19 pandemic. The impact of the decrease observed in screening and diagnosis is already evident in the number of women undergoing chemotherapy. These data will continue to be monitored in the coming months when only then will data be available for staging at diagnosis.[Table: see text]
Patient Reported Outcomes (PROs) are a report that comes from patients on a specific subject, describing how they feel about a condition or therapy. The term includes a range of constructions and methodology and can cover concepts such as symptoms to physical assessment, well-being and social involvement. The process can be described as a measure of patient reported outcome (Patient Reported Outcome Measure -PROM). In oncology, PROMs help healthcare professionals and systems to reduce the impact of treatment on patient's quality of life. In recent years, several studies have shown improvement in the evaluated outcomes. In our country, there is still little information on this subject, especially when it comes to cancer patients. Hence, we think that it is of utmost importance to review the particularities of this tool, in order to stimulate further discussion of the subject in our country.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
