1. INTRODUCTION
University hospitals (UHs) are centers for training human resources and developing technologies for the health field. These hospitals are dedicated to teaching, research, and extension. Their adequate provision of services to the population enables constant care and technical protocols for various pathologies. Their continuing education programs offer opportunities for technical updates to health system professionals (Educação, 2018).
Every UH has particularities and is highly heterogeneous in terms of installed capacity, technological incorporation, and comprehensive care. All UHs have a prominent role in the community in which they function (Educação, 2018). Of fifty Brazilian UHs, the Empresa Brasileira de Serviços Hospitalares (EBSERH) currently manages forty-one. Since 2011, when the Brazilian government established EBSERH, there have been significant challenges in managing the resources and policies of these university hospitals. The Hospital das Clínicas of the Federal University of Pernambuco (HC-UFPE) is a large UH (with an area of 64,000 m2) managed by EBSERH, with 2,823 employees, of which 1,124 are UFPE employees, 1,137 are EBSERH public employees, and 562 are outsourced, working in medium- and high-complexity pathologies. The HC-UFPE has 418 beds and performs a monthly average of 5,600 outpatient consultations and 748 hospitalizations. (BRAZIL, 2021).
Information and communications technology (ICT) plays a fundamental role in these hospitals, as observing the growing immersion of technology in health is easy, which facilitates medical procedures and optimizes administrative and governance processes, adding value to the hospital’s business. However, as they are primarily public institutions whose main area of activity is health, encountering some resistance regarding investments in technology is still common, in addition to the lack of strategic ICT alignment with other hospital areas. This problem is reflected in the provision of services to patients and in the acquisition and management of technological resources that streamline and improve the hospital’s business processes. Talmon et al. (2009) stated that health information is a significant investment area in the health sector and potentially affects all professionals and patients. Developing countries face several challenges compared with developed countries, such as a lack of infrastructure, time, cost, skilled labor, and regulatory policies in the health information field (Anwar & Shamim, 2011). Therefore, understanding these bottlenecks is necessary to improve business processes and effectively address strategic issues.
Therefore, an alternative for enabling projects that can minimize this gap is to implement enterprise architecture (EA). Gartner (2020) defined EA as a discipline for holistically leading corporate responses to disruptive forces by identifying and analyzing the execution of changes towards desired business visions and outcomes. EA aims to align a company’s strategy and configure its IT assets (Weil, 2007). EA allows organizations to see themselves in terms of a holistic and integrated view of their strategic direction, business practices, information flows, and technological resources (Bernard, 2012). Some countries’ governments have introduced EA to address IT challenges (Shaanika and Iyamu, 2015).
EA can offer subsidies to assist hospital management in decision-making. Strategic projects for the acquisition of ICT goods and services that align with corporate business and stakeholders’ needs are also expected. The Information and Communications Technology Strategic Plan (ICTSP) is a formal document that defines the entire strategic field in which hospital ICT must operate, including goals, strategic objectives, and guiding pillars of ICT governance in UHs. Implementing the ICTSP leads an organization along a path designed to enable it to fully leverage and exploit information technology (IT) for opportunities that manifest in the market (Gabriel and Lupiana, 2018).
Concerning EA, building information systems (IS) architecture is a phase of the architecture development method (ADM) to be achieved, according to The Open Group Architecture Framework (TOGAF) (Group, 2020). In this phase, we describe the information system architecture for an architectural project, including the development of data and application architecture. Its main objectives are to develop the target data architecture that enables the business architecture and architecture vision to address the statement of architecture work and stakeholder concerns and identify candidate architecture roadmap components based on gaps between the baseline and target data architectures (Group, 2020).
Although several frameworks are available in the literature to support the implementation of EA, which we found during a Systematic Review of the Literature (SLR), which will be presented later, still lacking models that provide adequate support to assist in the construction of the IS architecture in UHs. We miss a model that provides a well-defined step-by-step guide so that professionals and researchers can guide themselves during the construction of EA artifacts. Similarly, empirical studies on EA remain lacking (Boh and Yellin, 2007; Bradley et al., 2011; Kappelman et al., 2008); Niemi, 2006; Radeke, 2010; Tamm et al., 2011). A significant challenge in the area is the lack of integration between
