RESUMO
Abstract COVID-19 pandemic implied new biosafety recommendations to avoid dissemination of SARS-CoV-2 virus within healthcare centers. Changes on recommended personal protective equipment (PPE), decontamination protocols and organization of patient demand resulted may result in cost variation. Based on this, the present study aimed to evaluate the economic impact of new biosafety recommendations for oral healthcare assistance during COVID-19. An Activity Based Costing evaluation was used to calculate the acquisition of PPE and decontamination solutions recommended for dental practice during COVID-19 pandemic in Brazil. PPE and decontamination solutions quantity and frequency of use were based on the newly COVID-19 recommendations. Costs (in Brazilian Real - R$) for biosafety recommendations pre- and post-COVID-19 were outlined and calculated for each patient, service shift and year. A sensitivity analysis considered 20% variation of direct costs. Previously to COVID-19 pandemic, direct costs of biosafety recommendations consisted of R$0.84 per patient, R$6.69 per service shift and R$3,413.94 per year. Post-COVID-19 costs of biosafety recommendations resulted in R$16.01 per patient, R$128.07 per service shift, and R$32,657.96 per year. Yearly costs can vary between R$26,126.37 and R$39,189.56. The annual budget increase necessary to adopt post-COVID biosafety recommendations was R$29,244.02. Newly biosafety recommendations increased significantly the costs of oral healthcare assistance during COVID-19 pandemic. Decision making of healthcare managers must consider rational and equity allocation of financial resources.
