ABSTRACT
Background: The economic impact associated with the treatment strategies of coronavirus disease-2019 (COVID-19) patients by hospitals and health-care systems in Brazil is unknown and difficult to estimate. This research describes the investments made to absorb the demand for treatment and the changes in occupation rates and billing in Brazilian hospitals. Methods: This research covers the initial findings of "COVID-19 hospital costs and the proposition of a bundled reimbursement strategy for the health-care system," which includes 10 hospitals. The chief financial officer, the chief medical officer, and hospital executives of each participating hospital provided information regarding investments attributed to COVID-19 patient treatment. The analysis included variations in occupation rates and billing from 2019 to 2020 observed in each institution, and the investments for medical equipment, individual protection materials and building construction per patient treated. Results: The majority of hospitals registered a decrease in hospitalization rates and revenue from 2019 to 2020. For intensive care units (ICUs), the mean occupancy rate ranged from 88% to 83%, and for wards, it ranged from 85% to 73%. Monthly average revenue decreased by 10%. The mean hospital investment per COVID-19 inpatient was I$6800 (standard deviation 7664), with the purchase of ventilators as the most common investment. For this item, the mean, highest and lowest acquisition cost per ventilator were, respectively, I$31â¯468, I$48â¯881 and I$17â¯777. Conclusion: There was significant variability in acquisition costs and investments by institution for responding to the COVID-19 pandemic. These findings highlight the importance of continuing microeconomic studies for a comprehensive assessment of hospital costs. Only with more detailed analyses, will it be possible to define and drive sustainable strategies to manage and reimburse COVID-19 treatment in health-care systems.
ABSTRACT
Objetivos: Avaliar o foto-eletrocardiograma (foto-ECG), como uma ferramenta de segunda opinião formativa a distância.Métodos: Cinquenta eletrocardiogramas (ECGs) em papel milimetrado foram fotografados duas vezes, a primeira utilizando-se uma câmera digital Canon, na resolução 0,3 megapixel, e a segunda com um celular Nokia com câmera acoplada, na resolução 2,0 megapixels, gerando 100 foto-ECGs. Por meio de estudos-piloto, definiu-se o método de aquisição das imagens. Os 100 foto-ECGs foram randomizados, criptografados e enviados a um cardiologista remoto por e-mail; enquanto os 50 ECGs em papel milimetrado lhe foram entregues pessoalmente, sem randomização. Sexo e idade foram as únicas informações dos pacientes disponibilizadas ao especialista.Resultados: A análise dos dados demonstrou divergência em 14 dos 50 laudos (28%) na comparação dos ECGs originais com os foto-ECGs adquiridos pela câmera Canon e de 13 dos 50 laudos (26%) entre os laudos dos ECGs originais e dos foto-ECGs capturados pelo celular Nokia. Houve concordância considerável (Kappa=0,356) entre as interpretações de foto-ECGs e ECGs em papel, tanto para o celular Nokia quanto para a câmera Canon.Conclusões: A concordância entre o foto-ECG e os traçados originais demonstrou que o método descrito nesse estudo tem potencial de ser utilizado como uma ferramenta de auxílio à prática clínica, desde que a obtenção dos foto-ECGs seja adaptada de forma a melhorar as imagens dos exames. Apenas com concordância boa a ótima em relação aos ECGs originais, o foto-ECG possibilitará a segunda opinião formativa a distância, conferindo melhores opções diagnósticas e terapêuticas...
Aims: This study aimed to evaluate the photo-electrocardiogram (photo-ECG), as an alternative tool to enable remote formative second opinion in cardiology.Methods: Fifty paper electrocardiograms (ECGs) were photographed two times, the first using a Canon digital camera, 0.3 megapixel resolution, and the second using a Nokia mobile phone integrated camera, 2.0 megapixel resolution, resulting in 100 Photo-ECGs. A pilot study was responsible for determining the acquisition method. The 100 Photo-ECGs were randomized, encrypted and sent by e-mail to a remote cardiologist, while the 50 paper ECGs were delivered to him in person, without randomization. Gender and age were the only patient information made available to the specialist.Results: Data analysis demonstrated a disagreement in 14 of 50 interpretations (28%) when comparing paper ECGs to the Canon camera photo-ECGs and in 13 of 50 interpretations (26%) when comparing paper ECGs to the Nokia camera photo-ECGs. The Kappa test revealed a fair agreement (Kappa=0.356) between interpretations when comparing the original ECGs to their respective photo-ECGs for both camera devices.Conclusion: The concordance between photo-ECGs and original tracings demonstrated that the method described herein has the potential for use as a tool to assist clinical practice, provided that the acquisition of photo-ECGs is adapted so as to improve exam images. Only with good to very good concordance between the original ECGs and photo-ECGs will remote formative second opinion be possible, giving better diagnostic and therapeutic options...
