This qualitative document analysis used a rhetorical analysis based on the theory of argumentation of Perelman and Obrecht’s-Tyteca (2005), which considered that discursive techniques and convincing arguments overlap the spoken language. Moreover, spoken language can develop using pre-selected persuasive elements as a starting point for an argument, that is the articulation of ideas, dialogues, and controversies, these being essential requirements for a pluralistic society. The rhetorical analysis consists of looking for the conditions that allow qualifying the speech about an action or a rule; it means determining what is valid and deserves to be adopted in human relationships. This approval depends on how the arguments are used to motivate the audience to make certain choices over others and, above all, to justify these, so that they become acceptable and approved by others (Lima JdC 2020).
The rhetorical analysis considered the analysis of techniques and arguments aimed at managers and health professionals (private auditorium) by WHO and PAHO (universal speakers), and MH, CFM, and COFEN (private speakers).
The document analysis considered the social context and health crisis of the COVID-19 pandemic to search for official publications from WHO, PAHO, MH, CFM, and COFEN regarding digital health as care, coping, and solving strategy of PHC. PHC teams in Brazil must have at least a physician and a nurse, justifying the inclusion of documents from CFM and COFEN (Brasil 2017).
The scheme for document search is presented in Fig. 1. The documents were searched and selected between December 2021 and June 2022 on the official websites of WHO (https://apps.who.int/iris/), PAHO (https://www.paho.org/pt), MH (https://www.gov.br/saude/pt-br), CFM (https://portal.cfm.org.br), and COFEN (http://www.cofen.gov.br/). The search terms individually used were “digital health”, “telehealth”, “telemedicine”, “e-health”, “telessaúde”, “telenfermagem”, “telemedicina”, and “saúde digital.” Two independent researchers (AJdA and IdSS) scanned the websites twice and found 47 documents. For inclusion in the study considered the following documents for analysis: recommendations, informative pages, guidelines, resolutions, laws, and ordinances published from March 1, 2020, to June 3, 2022. After applying the selection criteria, 27 documents were excluded for not complying with the pre-analysis of the documents.
The documents met the premises proposed by Cellard (2012) before document analysis: elements of the problem or theoretical framework (theme), context (year of publication), authors (institutional agency), interests, authenticity and reliability (title and source of access), nature of the text (type of document), and key concepts (summary).
Twenty documents met the eligibility criteria, of which three were from WHO (one informative page and two guidelines), four from PAHO (four informative pages), seven from MH (one law and six ordinances), three from CFM, and three from COFEN. The critical pre-analysis of documents is presented in Chart 1.
Data were accessible to the public and directed to the universal auditorium of health systems. Data also composed the second stage of a broader study entitled "Evaluation of the quality of telemedicine in Primary Health Care in the context of COVID-19", which was approved by the research ethics committee of the Hospital Universitário Onofre Lopes of the Federal University of Rio Grande do Norte, Brazil (registry no. 48655521.9.0000.52).
CONTEXTUALIZATION AND ANALYSIS OF THE DOCUMENTS
In this sense, WHO and PAHO developed instructional and informative pages (01, PAHO; 02, PAHO; 03, PAHO; 04, PAHO; 05, WHO; 06, WHO) with linking arguments that led to agreements related to the real and preferable context considering the coexistence of the pandemic with health needs. The arguments were based and justified on the structure of reality and contained strategies and guidelines for using ICTs as a digital solution to manage the new challenges in health care during the COVID-19 pandemic. In addition, the WHO launched the "Global strategy on digital health 2020–2025" (07, WHO) to help governments, ministries, and secretaries improve health using the development, adoption, and access to digital solutions. The aim was also to prevent, detect, and respond to epidemics and pandemics using infrastructure and applications that allowed countries to use data for promotion and well-being and achieve health-related sustainable development goals.
In March and April 2020, PAHO released information about teleconsultations during the COVID-19 pandemic, using the information pages “Teleconsultation during a pandemic” and “The potential of frequently used information technologies during the pandemic.” The documents encouraged diagnostic or therapeutic counseling using digital health, considering it an important strategy for public health emergencies. In addition, PAHO predicted the collapse of health services, defended the use of ICTs for information and interaction, stimulated teleconsultation to virtually help services or situations, and indicated minimum requirements for its use in PHC (01, PAHO; 02, PAHO).
On May 23, 2020, PAHO released an informative page (03, PAHO) arguing that a solid health information system may help the PHC in health promotion, prevention, and rehabilitation during the COVID-19 pandemic. In addition, the focus should be on responding to COVID-19 by integrating national and local systems, digital health, and ICTs to effectively identify, inform, and analyze cases and contacts, promptly search and detect cases, and identify and follow up on the population at risk. A solid health information system would maintain essential services during the COVID-19 pandemic and allow hospital discharge using teleconsultations. Besides, the hospital discharge would rely on follow-up, control, and rehabilitation monitoring, using medical records and electronic prescriptions in high-risk groups for severe COVID-19. Moreover, PAHO indicated that ICTs improve the cost-effectiveness of treatments, enabling the regular and uninterrupted operation of essential services.
On August 11, 2020, PAHO published the document “Digital health: a strategy to maintain health care for people living with non-communicable diseases during COVID-19” (04, PAHO), containing the three types of linking arguments. The document evidenced, with examples, how digital health tools may be applied in PHC for people with non-communicable diseases (e.g., cardiovascular or respiratory diseases, cancer, diabetes, smoking) to encourage the continuity of care during the COVID-19 pandemic. The document also considered the relocation of health professionals to combat COVID-19 and the interruption of the offer of essential services, such as public transportation (hampering the commuting of individuals and health professionals), outpatient clinics, and appointments.
The WHO published two documents (05, WHO; 06, WHO) addressing the importance of digital solutions for proximity and contact tracing. With universal writing and based on the structure of reality, the WHO stated that member States could use digital health to achieve public health goals, protect fundamental rights, and consider ethical principles (e.g., transparency, data minimization, and data storage that preserves privacy, security, accountability, and social engagement). As universal speakers, PAHO and WHO used connection arguments that influenced countries to develop digital health solutions that possibly improved and managed the quality of health care services.
Regarding the adoption of digital health in PHC by Brazilian health agencies, the initiatives were mostly conditioned to the exceptionality of the pandemic moment. The MH published Ordinance No. 467 of March 20, 2020 (08, MH), about the exceptional and temporary use of telemedicine to regulate and operationalize the SUS and supplementary and private health. This ordinance was endorsed with Law No. 13989 of April 15, 2020 (09, MH), which deliberated the use of telemedicine during a public health emergency of international importance. In addition, Ordinance No. 1768/2021 (12, MH) integrated the National Health Information and Informatics Policy (PNIIS) to assist information systems in health, support a digital transformation of the work process, improve governance in the use of information, ICT solutions, and digital health, and maintain transparency, security, and access to health information by the population.
With connection arguments based on the structure of reality, Ordinance No. 467 (08, MH) and Law No. 13989 (09, MH) stated that remote interaction could contemplate pre-clinical care, support assistance, consultation, monitoring, and diagnosis using ICTs. Also, the law determined that telemedicine should follow the usual normative and ethical standards of face-to-face care, including financial ones, since telemedicine was a medical exercise to assist, research, prevent disease and injury, and promote health.
Law No. 13989 (09, MH) encouraged the expansion of digital health along with the CFM, which regulated the emission of digital medical documents and established an integrated system to collect them with Resolutions No. 2299 (16, CFM) and 2296 (17, CFM). These resolutions guided the medical activity during the validity of Law No. 13989, aiming to improve communication between the CFM and professionals and data security and standardize the emission of digital medical documents.
COFEN standardized telenursing during the pandemic by Resolution No. 634/2020 of March 26, 2020 (15, COFEN). Supported by arguments based on the structure of reality, the decision of the autarchy aimed to regulate population access to nursing consultations and minimize the risks of COVID-19 transmission.
On February 3, 2022, COFEN published Resolution No. 689/2022 (18, COFEN), which regulated electronic prescriptions by the nursing team. In this context, on May 4, 2022, the CFM released Resolution No. 2314/2022 (19, CFM), regulating telemedicine for physicians in Brazil. The resolution resulted from a debate with medical entities and specialists and regulated digital health regardless of the health crisis, replacing CFM Resolution No. 1643/2002. Furthermore, COFEN published Resolution No. 696/2022 (20, COFEN), standardizing the permanent use of telenursing. Via arguments based on the structure of reality (e.g., evidence proving the effectiveness of use and strict ethical, technical, and legal parameters), professional councils, as private speakers, aimed to adapt to the Brazilian scenario and strengthen the implementation of digital health.
On June 2, 2022, the MH published Ordinance No. 1348 (13, MS), regulating the definitive use of digital health in Brazil. Following COFEN and CFM, the MH reinforced the importance of digital health as a complementary strategy in health actions. It also launched a pilot project entitled Basic Digital Health Unit (BDHU) to encourage municipalities to adopt digital health in PHC, considering the national geographic diversity and remote municipalities with poor access to essential services. The pilot project was regulated by its ordinance, and criteria were established for adherence and funding based on PNIIS and the National Policy for Primary Care.
BDHU was established in PHC using Ordinance No. 1355 of June 3, 2022 (14, MH), aiming at remote rural municipalities. The goal was to spread digital health in basic health units to expand access, solvability, and integration of PHC services with Health Care Networks. With this ordinance, the MH showed city managers interest in financing and encouraging digital health implementation in PHC from 2020 to 2028, starting in remote municipalities and expanding to the entire Brazilian territory.
