Solving Problems Due to Hurricane Maria and COVID-19: CT Trends in Puerto Rico Before, During, and Beyond Public Health Crises

Our objective was to evaluate the impact of recent public health crises on radiology CT services in Puerto Rico. We gathered and analyzed CT statistics from 2 of Puerto Rico's major private hospital groups and obtained monthly data from January 2016 to March 2021. We quantified short- and long-term impacts of Hurricane Maria (September 2016-August 2017, September 2017-August 2018, September 2018-August 2019) and COVID-19 (April 2019-March 2020, April 2020-March 2021) by calculating month-to-month and year-to-year percentage differences for each hospital and all hospitals combined for the dates leading up to, in the immediate aftermath, and following these major events. Despite short-term effects throughout September from Hurricane Maria, there were no noticeable year-to-year differences in the total number of CT studies performed. Both March and April 2020 highlighted the instantaneous impact caused by COVID-19; these months contributed less than 6% of the total yearly scans performed between April 2019 and March 2020 and April 2020-March 2021 for all the hospitals individually. Hurricane Maria exerted a short-term impact on CT studies performed throughout September 2017. COVID-19 also demonstrated immediate yet prolonged effects on the number of CT studies performed with all 3 hospitals reporting decreases between a full pandemic year and the year prior. Our results support fortifying medical and societal infrastructure to better prepare for future natural and public health disasters, particularly in Puerto Rico and similarly resourced areas, to maintain steady, if somewhat diminished, radiology services such as CT for regular and emergency purposes.
