ABSTRACT
Introduction: Cancer patients have a high risk of severe COVID-19 and complications from it. Although the COVID-19 pandemic has led to an increase in the conduction of clinical trials (CTs), there is a scarcity of data on CT participation among cancer patients. We aimed to describe the level of participation in a COVID-19 CT, willingness to participate, as well as trust in sources of information for CTs among persons with and without a previous cancer diagnosis in Puerto Rico. Method(s): Data collected from November 2021 to March 2022 from two cross-sectional studies were merged and used for analysis. Informed consent, telephone, face-to-face, and online interviews were conducted among participants >=18 years old living in Puerto Rico (n=987). Descriptive statistics and bivariate analysis (Fisher's exact text and chi-squared test) was done to describe the outcomes of interest, overall and by cancer status. Result(s): Mean age of participants was 41+/-15.5 years. Most participants were women (71.3%), with an educational level greater than high school (89.5%) and with an annual family income below $20,000 (75.1%). Overall, 4.4% of participants (n=43) reported history of cancer diagnosis. Only 1.8% of the population reported to have participated in a COVID-19 CT to receive either a treatment or vaccine;stratifying by cancer, none of the cancer patients had participated in a COVID-19 CT, and only 1.9% of non-cancer patients participated. While 37.0% of the participants indicated being very willing to sign up for a CT assessing COVID-19 treatment, willingness was higher in cancer patients (55.8%) than among participants without cancer (36.1%). Regarding trust in sources of information for CTs, the level of trust ("a great deal/a fair amount") was higher for their physicians (87.6%), researchers (87.0%), the National Institute of Health (86.7%), their local clinics (82.9%), and a university hospital (82.7%), while it was lower for a pharmaceutical company (64.0%), and for friend, relative, or community leader (37.6%);no differences were observed by cancer status. Conclusion(s): While participation in COVID-19 CTs was extremely low in the study population, the willingness to participate was higher among cancer patients. Education on CTs and their availability are necessary to increase participation in this understudied group. Such efforts will enhance the representation of Hispanic and vulnerable populations, such as cancer patients, on COVID-19 CTs, and thus proper generalizability of study findings in the future.
ABSTRACT
INTRODUCTION: Puerto Rico has endured three major environmental and public health crises (Hurricane Irma, Hurricane Maria, the unprecedented seismic activity of January 2020) and the coronavirus disease 2019 (COVID-19) pandemic during the past 5 years. All these events might lead to an unquestionable deleterious impact in the prevention of cancer and across the cancer continuum, exacerbating cancer health disparities in the future. Cancer screening plays a critical role in early cancer detection. COVID-19 has significantly hampered screening programs in many countries' cancer screening infrastructure and services, affecting adherence. Cancer is the leading cause of morbidity and mortality in Puerto Rico. Limited information is available about the impact the current pandemic on colorectal cancer screening. In this study, we aim to describe the impact of the COVID-19 pandemic on colorectal cancer screening in 2020 and assess if this impact varied by health regions. METHOD(S): This study analyzed administrative data claims from the Public Health System of Puerto Rico which is managed by the Government of Puerto Rico through the Health Insurance Administration. The Current Procedural Terminology (CPT) codes included for this study were (81528, 82270, G0104, G0105, G0121, G0328, G0464). To assess changes in the numbers of colorectal cancer screening claims between the incurred year (2016 and 2020), Poisson regression was used. Initially, we fitted this model with only the incurred year as the predictor and offsetting the model with the annual average of total insured (univariate model). Based on this model, we estimate the magnitude of association between the number of claims and incurred year using the Prevalence Ratio (PR) of claims. Lastly, Poisson univariate regression model were used for each of the seven health regions (Ponce, Bayamon, Caguas, Mayaguez, Metro, Arecibo and Fajardo) to assess potential geographic disparities. RESULT(S): The numbers of colorectal cancer screening claims significantly decreased by 40% (PRcrude: 0.60, 95%CI: 0.59, 0.62) in 2020 when compared to 2016. However, when adjusting for claim incurred month, sex, health region and offsetting the model with the annual average of total insured, the numbers of colorectal cancer screening claims significantly decreased by 34%, (PRadj: 0.66, 95%CI: 0.64, 0.67). The numbers of colorectal cancer screening claims significantly decreased in all health regions in 2020 when compared to 2016 (p<0.05). However, the most impacted region was the Eastern region, Fajardo, with a 64% (PRFajardocrude: 0.36, 95%CI: 0.30, 0.42) significant decrease in numbers of colorectal cancer screening claims. CONCLUSION(S): COVID-19 had a profound negative effect on colorectal screening in Puerto Rico. Moreover, despite the beneficiaries of this governmental health plan sharing similar sociodemographic and socioeconomic background, regional differences were observed.
